DESCRIPTION OF EMBODIMENTS
<First Embodiment>
[0026] A first embodiment that embodies a polyester synthetic fiber treatment agent of the
present invention (also referred to hereinafter as treatment agent) will now be described.
The treatment agent of the present embodiment contains a silicone (A), a silicone
(B), and an anionic ingredient. The treatment agent may optionally further contain
a silicone (C). The treatment agent may further contain a nonionic surfactant and/or
a silicone (D).
(Silicone (A))
[0027] The silicone (A) used in the treatment agent of the present embodiment is a modified
silicone having an amino group in the molecule. It may be a terminal type amino-modified
silicone, in which an amino group is introduced to a terminal silicon atom of polydimethylsiloxane
that is the main chain, or may be a side-chain type amino-modified silicone, in which
an amino group is introduced to a silicon atom other than the terminal of the main
chain. As the silicone (A), a commercial product specified by viscosity and functional
group equivalent weight may be used.
[0028] The silicone (A) has a viscosity at 25°C of preferably not less than 10 mPa·s and
not more than 30,000 mPa·s and more preferably not less than 25 mPa·s and not more
than 10,000 mPa·s. Any combination of the upper and lower limits may be used. By specifying
to be in such range, the handleability of formulation is improved and benefits of
the present invention can be exhibited more effectively.
[0029] The silicone (A) has a functional group equivalent weight of preferably not less
than 100 g/mol and not more than 20,000 g/mol and more preferably not less than 500
g/mol and not more than 150,00 g/mol. Any combination of the upper and lower limits
may be used. By specifying to be in such range, the compatibility with polyester synthetic
fibers is improved and the flexibility of fibers with the treatment agent adhered
thereto can be exhibited more effectively.
[0030] The silicone (A) may be used either alone or in combination of two or more types
as appropriate.
[0031] The lower limit of the silicone (A) content in the treatment agent is preferably
not less than 3% by mass and more preferably not less than 5% by mass. When this content
is not less than 3% by mass, the flexibility of fibers with the treatment agent adhered
thereto can be improved. The upper limit of the silicone (A) content in the treatment
agent is preferably not more than 85% by mass and more preferably not more than 80%
by mass. When this content is not more than 85% by mass, the bulkiness of fibers with
the treatment agent adhered thereto can be improved. Any combination of the upper
and lower limits may be used.
(Silicone (B))
[0032] The silicone (B) used in the treatment agent of the present embodiment is a silane
coupling agent having at least one functional group selected from the group consisting
of a methoxy group, an ethoxy group, an amino group, and an isocyanate group but not
including an epoxy group in the molecule. The silicone (B) can improve the flexibility
of fibers with the treatment agent applied thereto. Specific examples of the silicone
(B) include N-2-(aminoethyl)-3-aminopropylmethyldimethoxysilane, 3-aminopropyltriethoxysilane,
N-2-(aminoethyl)-3-aminopropyltrimethoxysilane, methyltrimethoxysilane, methyltriethoxysilane,
and 3-isocyanatopropyltriethoxysilane.
[0033] The silicone (B) may be used either alone or in combination of two or more types
as appropriate.
[0034] The lower limit of the silicone (B) content in the treatment agent is preferably
not less than 0.5% by mass and more preferably not less than 1% by mass. When this
content is not less than 0.5% by mass, the flexibility of fibers with the treatment
agent applied thereto can be improved. The upper limit of the silicone (B) content
in the treatment agent is preferably not more than 30% by mass and more preferably
not more than 25% by mass. When this content is not more than 30% by mass, the stability
of the treatment agent during use, especially the emulsion stability when the treatment
agent is put in an emulsion state can be improved. Any combination of the upper and
lower limits may be used.
[0035] The lower limit of the silicone (B) content in the treatment agent assuming that
the silicone (A) content in the treatment agent is 100 parts by mass is preferably
not less than 5 parts by mass and more preferably not less than 6 parts by mass. When
this content is not less than 5 parts by mass, the flexibility of fibers with the
treatment agent applied thereto can be improved. The upper limit of the silicone (B)
content in the treatment agent assuming that the silicone (A) content in the treatment
agent is 100 parts by mass is preferably not more than 200 parts by mass and more
preferably not more than 150 parts by mass. When this content is not more than 200
parts by mass, the flexibility of fibers with the treatment agent applied thereto
can be improved.

[0036] The silicone (C) used in the treatment agent of the present embodiment is at least
one selected from the group consisting of silicone resins, dimethyl silicones, and
alkyl-modified silicones. The silicone (C) may be contained optionally in the treatment
agent.
[0037] Examples of the silicone resins include MQ silicone resins, MDQ silicone resins,
T silicone resins, and MTQ silicone resins.

be arranged as a two-component treatment agent or a three-component treatment agent
such as described below.
[0082] The two-component treatment agent is arranged as a set that includes a first component
of the two-component polyester synthetic fiber treatment agent (referred to hereinafter
as "first-of-two-component treatment agent") containing the silicone (A), the anionic
ingredient, and optionally the silicone (C) and a second component of the two-component
polyester synthetic fiber treatment agent (referred to hereinafter as "second-of-two-component
treatment agent") containing the silicone (B). The first-of-two-component treatment
agent contains the silicone (C) such that its content in a mixture of the first-of-two-component
treatment agent and the second-of-two-component treatment agent is less than 10% by
mass. The first-of-two-component treatment agent may also further contain the silicone
(D) and/or the nonionic surfactant. The two-component treatment agent is constituted
of the first-of-two-component treatment agent and the second-of-two-component treatment
agent that are separate from each other before use, for example, during preservation
or during distribution. In use, the first-of-two-component treatment agent and the
second-of-two-component treatment agent are mixed with each other to prepare the two-component
treatment agent.
[0083] The three-component treatment agent is arranged as a set that includes a first component
of the three-component polyester synthetic fiber treatment agent (referred to hereinafter
as "first-of-three-component treatment agent") containing the silicone (A), the anionic
ingredient, and optionally the silicone (C), a second component of the three-component
polyester synthetic fiber treatment agent (referred to hereinafter as "second-of-three-component
treatment agent") containing the silicone (D), and a third component of the three-component
polyester synthetic fiber treatment agent (referred to hereinafter as "third-of-three-component
treatment agent") containing the silicone (B).
[0084] The first-of-three-component treatment agent contains the silicone (C) such that
its content in a mixture of the first-of-three-component treatment agent, the second-of-three-component
treatment agent, and the third-of-three-component treatment agent is less than 10%
by mass. One of either or both of the first-of-three-component treatment agent and
the second-of-three-component treatment agent may contain the nonionic surfactant.
The anionic ingredient may also be contained in the second-of-three-component treatment
agent.
[0085] The three-component treatment agent is constituted of the first-of-three-component
treatment agent, the second-of-three-component treatment agent, and the third-of-three-component
treatment agent that are separate from one another before use, for example, during
preservation or during distribution. In use, the first-of-three-component treatment
agent, the second-of-three-component treatment agent, and the third-of-three-component
treatment agent are mixed with one another to prepare the three-component type treatment
agent.
(Solvent)
[0086] The treatment agent of the present embodiment may be mixed as necessary with a solvent
to prepare a composition containing a polyester synthetic fiber treatment agent (hereinafter
referred to as "treatment agent-containing composition") and be preserved or distributed
in the form of the treatment agent-containing composition.
[0087] The solvent is a solvent having a boiling point at atmospheric pressure of not more
than 105°C. Examples of the solvent include water and an organic solvent. Specific
examples of the organic solvent include lower alcohols, such as ethanol and propanol,
and low polarity solvents, such as hexane. The solvent may be used either alone or
in combination of two or more types as appropriate. Among these, a polar solvent,
such as water or a lower alcohol, is preferable from a standpoint of being excellent
in terms of the dispersibility and solubility of the respective ingredients and water
is more preferable from a standpoint of being excellent in handleability.
[0088] Assuming that the sum of the amounts of the treatment agent and the solvent contained
in the treatment agent-containing composition is 100 parts by mass, the amount of
the treatment agent contained in the treatment agent-containing composition is not
less than 10 parts by mass and not more than 80 parts by mass.
[0089] Effects of the treatment agent of the first embodiment will now be described.
(1-1) The treatment agent of the first embodiment contains the specific silicones
and the anionic ingredient described above. Therefore, the antistatic property and
the flexibility of fibers with the treatment agent applied thereto can be improved.
Also, the stability of the treatment agent, especially the emulsion stability when
the treatment agent is put in an emulsion state can be improved. Also, the bulkiness
of fibers with the treatment agent applied thereto can be improved.
(1-2) The treatment agent of the first embodiment may be arranged as a set that includes
the first-of-two-component treatment agent containing the silicone (A), the anionic
ingredient, and optionally the silicone (C) and the second-of-two-component treatment
agent containing the silicone (B). By such an arrangement, the formulation stability
and especially the preservation stability of the treatment agent can be improved.
(1-3) If the treatment agent of the first embodiment contains the silicone (D) and
the nonionic surfactant, it may be arranged as a set that includes the first-of-three-component
treatment agent containing the silicone (A), the anionic ingredient, and optionally
the silicone (C), the second-of-three-component treatment agent containing the silicone
(D), and the third-of-three-component treatment agent containing the silicone (B).
The nonionic surfactant may be contained in one of either or both of the first-of-three-component
treatment agent and the second-of-three-component treatment agent. By such an arrangement,

<Seventh Embodiment>
[0121] Next, a seventh embodiment that embodies a method for treating a polyester synthetic
fiber of the present invention (hereinafter referred to as "fiber treatment method")
will be described.
[0122] The fiber treatment method of the present embodiment is characterized in that in
a case of a two-component treatment agent, a treatment agent dilute liquid containing
a solvent, the first-of-two-component treatment agent of the second embodiment, and
the second-of-two-component treatment agent of the third embodiment is applied to
a polyester synthetic fiber. The dilute liquid is prepared by, for example, adding
the first-of-two-component treatment agent or the first-of-two-component treatment
agent-containing composition and the second-of-two-component treatment agent to the
solvent. The dilute liquid is preferably prepared by adding the first-of-two-component
treatment agent-containing composition of the second embodiment and the second-of-two-component
treatment agent of the third embodiment to the solvent. The ratio of the first-of-two-component
treatment agent content and the second-of-two-component treatment agent content is
preferably such that as a mass ratio of nonvolatile contents, first-of-two-component
treatment agent/second-of-two-component treatment agent = 99.5/0.5 to 70/30. By specifying
to be in such range, the handleability can be improved. The term a nonvolatile content
as used herein refers to residue after sufficient removal of volatile matter by heat
treating an object at 105°C for 2 hours, that is, to absolutely dry matter.
[0123] The fiber treatment method of the present embodiment is characterized in that in
a case of a three-component treatment agent, a treatment agent dilute liquid containing
a solvent, the first-of-three-component treatment agent of the fourth embodiment,
the second-of-three-component treatment agent of the fifth embodiment, and the third-of-three-component
treatment agent of the sixth embodiment is applied to a polyester synthetic fiber.
The dilute liquid is prepared by, for example, adding the first-of-three-component
treatment agent or the first-of-three-component treatment agent-containing composition,
the second-of-three-component treatment agent or the second-of-three-component treatment
agent-containing composition, and the third-of-three-component treatment agent to
the solvent. The dilute liquid is preferably prepared by adding the first-of-three-component
treatment agent-containing composition of the fourth embodiment, the second-of-three-component
treatment agent-containing composition of the fifth embodiment, and the third-of-three-component
treatment agent of the sixth embodiment to the solvent.
[0124] The solvent used for producing the dilute liquid can be the same as exemplified in
the first embodiment. The dilute liquid preferably has a nonvolatile content of not
less than 0.01% by mass and not more than 10% by mass from a standpoint of, for example,
the handleability.
[0125] By using the first-of-two-component treatment agent and the second-of-two-component
treatment agent in combination or the first-of-three-component treatment agent, the
second-of-three-component treatment agent, and the third-of-three-component treatment
agent in combination, the mixing ratio of the respective components can be changed
as desired. Therefore, even if production conditions differ due to differences in
production equipment or differences in climate such as temperature and humidity, the
mixing ratio can be adjusted finely such that it is easy to prepare the treatment
agent or the dilute liquid for always imparting optimal fiber characteristics or fiber
production characteristics.
[0126] To emulsify the treatment agent, the respective treatment agents or compositions
may be mixed with the solvent and stirred using a known stirrer such as a homomixer,
a homogenizer, a colloidal mill, or a line mixer.
[0127] The fiber treatment method includes applying to a fiber the dilute liquid obtained
as described above, for example, in a spun yarn production step constituted of a fiber
spinning or drawing step or a finishing step.
[0128] Examples of the fiber to which the dilute liquid is applied include a polyester synthetic
fiber. Specific examples of the polyester synthetic fiber include polyethylene terephthalate
(PET), polytrimethylene terephthalate, polybutylene terephthalate, polyethylene naphthalate,
polylactic acid, and a composite fiber containing these polyester resins.
[0129] Use of the fiber is not restricted in particular, and example thereof include wadding,
a short fiber, a long fiber, a spun yarn, and a nonwoven fabric. Short fibers correspond
to those that are generally called staples and do not include long fibers that are
generally called filaments. The length of the short fiber is not restricted in particular
as long as it corresponds to that of short fiber in the art and is, for example, not
more than 100 mm. Among these, the dilute liquid of the present invention is preferably
applied to a polyester synthetic fiber for wadding. By being applied to a polyester
synthetic fiber for wadding, texture such as smoothness can be imparted to wadding,
for example, for stuffed toys, futons, and clothing.
[0130] The proportion of adhering the dilute liquid to the fibers is not limited in particular,
and the dilute liquid is adhered such that a final solids content is preferably not
less than 0.01% by mass and not more than 10% by mass and more preferably not less
than 0.1% by mass and not more than 3% by mass with respect to the fiber. By such
arrangement, the benefits due to the respective ingredients can be exhibited effectively.
The method for adhering the dilute liquid is not limited in particular, and a known
method such as a roller lubricating method, a guide lubricating method using a metering
pump, an immersion lubricating method, or a spray lubricating method can be used in
accordance with, for example, type, form, and use of the fiber. When an immersion
lubricating method is used, the immersion time is preferably not less than 1 minute
and not more than 5 minutes.
[0131] The fiber to which the dilute liquid has been adhered may be dried or heat-treated
using a known method. Water and other solvents are volatilized by the drying or heat
treatment, and the fiber to which the ingredients contained in the first treatment
agent, the second treatment agent, and the third treatment agent are adhered is thereby
obtained.
[0132] The heat treatment is performed to form a silicone coating on the fiber surface.
The heat treatment is preferably performed under a condition of not less than 100°C
and not more than 200°C. The heating time is set as appropriate in accordance with,
for example, treatment temperature and is preferably not less than 1 minute and not
more than 20 minutes and more preferably not less than 1 minute and not more than
15 minutes. By such heat treatment, the reaction between the silicone (A) and the
silicone (B) is promoted, and the silicone coating that is constituted of a crosslinked
polymer compound is formed on the fiber.
[0133] Effects of the fiber treatment method of the seventh embodiment will now be described.
With the seventh embodiment, the effects described below are provided in addition
to the effects of the above-described embodiments.
[0134] (7-1) The fiber treatment method of the seventh embodiment includes applying the
dilute liquid to a fiber, for example, in a spun yarn production step constituted
of a fiber spinning or drawing step or a finishing step. In particular, the dilute
liquid prepared by adding the first-of-two-component treatment agent or the first-of-two-component
treatment agent-containing composition of the second embodiment and the second-of-two-component
treatment agent of the third embodiment to the solvent is excellent in emulsion stability.
Alternatively, the dilute liquid prepared by adding the first-of-three-component treatment
agent or the first-of-three-component treatment agent-containing composition of the
fourth embodiment, the second-of-three-component treatment agent or the second-of-three-component
treatment agent-containing composition of the fifth embodiment, and the third-of-three-component
treatment agent of the sixth embodiment to the solvent is excellent in emulsion stability.
Benefits due to the respective ingredients on wadding, a short fiber, a long fiber,
a spun yarn, and a nonwoven fabric can thus be exhibited effectively.
[0135] (7-2) With the fiber treatment method of the seventh embodiment, the fiber to which
the treatment agent dilute liquid has been adhered may be heat-treated at not less
than 100°C and not more than 200°C. By such heat treatment, the reaction between the
silicone (A) and the silicone (B) is promoted, and the silicone coating that is constituted
of a crosslinked polymer compound is formed on the fiber. The more durable coating
thus formed can improve the flexibility of the fiber.
[0136] The above-described embodiments may be modified as follows. The embodiments can be
implemented in combination with the modifications described below within a range that
is not technically inconsistent.
· The method for preparing the treatment agent dilute liquid of the embodiments is
not limited in particular, and a method for preparation other than that described
in the section on the fiber treatment method of the seventh embodiment may be used.
For example, the respective silicones, the nonionic surfactant, and the anionic ingredient
described above may be mixed with one another and thereafter mixed with the solvent.
[0137] · The respective treatment agents, respective compositions, or dilute liquid of the
embodiments may further include another solvent, a stabilizer, an antistatic agent,
a binder, an antioxidant, an ultraviolet absorber, an organic acid, a surfactant other
than those mentioned above, and other ingredients that are ordinarily used in treatment
agents or the like as other ingredients for quality maintenance of the respective
treatment agents, respective compositions, or dilute liquid within a range that does
not impair the effects of the present invention. The other ingredients that are ordinarily
used in treatment agents other than the solvent are preferably of not more than 10%
by mass in each treatment agent from a standpoint of efficiently exhibiting the benefits
of the present invention.

Experimental Part 2 (Emulsifiability)
[0149] Each treatment agent prepared in Experimental Part 1 was diluted using ion exchanged
water to prepare a dilute liquid (emulsion) with a nonvolatile content of 1.0%. Emulsifiability
was evaluated as stability using the dilute liquid.
[0150] With the dilute liquid of each treatment agent, light transmittance (%) at a wavelength
of 750 nm was measured under conditions of 20°C and 60% RH. As a measuring device,
a spectrophotometer, UV-1800 SPECTROPHOTOMETER, manufactured by Shimadzu Corporation
was used. The emulsifiability of the dilute liquid was evaluated according to criteria
indicated below. The results are indicated in the "Emulsifiability" column of Table
1.
· Evaluation criteria of emulsifiability
[0151]
⊚ (satisfactory): There was no separation and the light transmittance was not less
than 50%.
∘ (fair): There was no separation and the light transmittance was not less than 30%
but less than 50%.
× (poor): There was separation.
Experimental Part 3 (Flexibility)
[0152] A wad of polyester synthetic fibers of 7 denier and a cut length of 32 mm generally
used for cushion wadding, futons, etc., was used for evaluation. The evaluation was
performed after first performing a washing operation with warm water of 40°C and then
drying for 2 hours at 80°C to eliminate influence of lubricants, etc., used in producing
the polyester synthetic fibers.
[0153] The treatment agent of each example prepared in Experimental Part 1 was diluted such
as to be of an effective ingredient concentration of 12.5% to prepare a dilute liquid
of emulsion form. 2.4 g of the emulsion were sprayed uniformly onto 100 g of the wad
of polyester synthetic fibers. Thereafter, heat treatment (drying) at 180°C was performed
for 10 minutes to prepare a sample wad for evaluation. 0.3 g of the treatment agent
are adhered to 100 g of the wad.
· Evaluation of flexibility
[0154] Flexibility of each dried sample wad was scored according to criteria indicated below
by five experts of texture evaluation of fibers and an average score of the five experts
was calculated by rounding off to two significant digits. The flexibility was evaluated
according to criteria indicated below based on the calculated average score. The results
are indicated in the "Flexibility" column of Table 1.
1 point: Has approximately the same flexibility as the wad of polyester synthetic
fibers without the treatment agent adhered thereto.
2 points: More flexibility is felt than the wad of polyester synthetic fibers without
the treatment agent adhered thereto.
3 points: Much more flexibility is felt than the wad of polyester synthetic fibers
without the treatment agent adhered thereto.
⊚ (satisfactory): The average score of the five experts was not less than 2.5 points.
∘ (fair): The average score of the five experts was not less than 2.0 points but less
than 2.5 points.
× (poor): The average score of the five experts was less than 2.0 points.
Experimental Part 4 (Antistatic property)
[0155] With each of the sample wads with the respective treatment agents adhered thereto
prepared in Experimental Part 3, 5 g were moisture conditioned for 24 hours inside
a thermostatic chamber at 20°C and 45% relative humidity. Thereafter, electrical resistances
of the polyester synthetic fibers were measured using a known resistance measuring
device and evaluated according to evaluation criteria indicated below. The results
are indicated in the "Antistatic property" column of Table 1.
· Evaluation criteria of antistatic property
[0156]
⊚ (satisfactory): Surface resistance was less than 1.0×1011 Ω.
∘ (fair): Surface resistance was not less than 1.0×1011 Ω but less than 1.0×1012 Ω.
× (poor): Surface resistance was not less than 1.0×1012 Ω.
Experimental Part 5 (Bulkiness)
[0157] Bulkiness was evaluated by measuring compressive elastic recovery rate. The compressive
elastic recovery rate was measured by a test method similar to that of JIS L2001.
[0158] With each of the sample wads with the respective treatment agents adhered thereto
prepared in Experimental Part 3, 40 g were fed into a roller carding machine to prepare
web of 30 cm × 100 cm with the corresponding treatment agent adhered thereto. The
web was cut out to prepare four sheets of fabric of 15 cm × 15 cm. The four sheets
of fabric were overlapped such that fiber directions were mutually orthogonal to prepare
a rectangular parallelepiped body.
[0159] After leaving still for 30 minutes at 20°C and 40% RH, a metal plate (135 g) of 15
cm × 15 cm was placed on the rectangular parallelepiped body and a height (h1) of
the rectangular parallelepiped body after 1 minute was recorded in 0.1 cm units. Further,
a weight of 1,125 g was placed on the metal plate and, after leaving still for 24
hours, was removed upon recording the height (h2). The height (h3) of the rectangular
parallelepiped body 1 minute after removing the weight was recorded.
[0160] The recovery rate was calculated by a formula indicated below.

[0161] It was judged that the higher the recovery rate, the better the bulkiness of the
test wad.
@ (satisfactory): The recovery rate (%) was not less than 80%.
∘ (fair): The recovery rate (%) was not less than 50% but less than 80%.
× (poor): The recovery rate (%) was less than 50%.
Experimental Part 6 (Preparation of first-of-two-component treatment agents)
(First-of-two-component treatment agent (P-1))
[0162] A first-of-two-component treatment agent (P-1) containing 6.3 parts (%) of the modified
silicone having an amino group (side-chain type; viscosity: 6,000 mPa·s, functional
group equivalent weight: 11,000 g/mol) (A-1) as the silicone (A), 84.2 parts (%) of
the both-terminal silanol-modified silicone (number average molecular weight: 100,000)
(D-1) as the silicone (D), 4.2 parts (%) of sodium dodecyl sulfonate (E-1) as the
anionic ingredient, and 5.3 parts (%) of polyoxyethylene (6) polyoxypropylene (2)
dodecyl ether (F-1) as the nonionic surfactant was prepared.
(First-of-two-component treatment agents P-2 to P-31)
[0163] First-of-two-component treatment agents P-2 to P-31 were prepared in the same manner
as the first-of-two-component treatment agent (P-1) such as to contain the silicones
(A), the silicones (C), the silicones (D), the anionic ingredients, and the nonionic
surfactants at the amounts indicated in Table 2.
[0164] The types and contents of the silicones (A), the types and contents of the silicones
(C), the types and contents of the silicones (D), the types and contents of the anionic
ingredients, and the types and contents of the nonionic surfactants are respectively
indicated in the "Silicone (A)" column, the "Silicone (C)" column, the "Silicone (D)"
column, the "Anionic ingredient" column, and the "Nonionic surfactant" column of Table
2.
