Description of the Related Art
[0002] For example, patent document 1 discloses a technique of knitting Afghan knitted fabric
in which hue changes in a complex manner depending on the viewing angle by forming
a low region section lowered in a recessed form and a high region section raised in
a projecting form on the surface of the Afghan knitted fabric, using different colors
between the low region section and the high region section, by hand knitting using
crochet hook. The change in hue occurs when the low region section appears and disappears
depending on the angle of viewing the Afghan knitted fabric.

SUMMARY OF THE INVENTION
[0004] However, a technique of knitting a knitted fabric in which the appearance differs
depending on the viewing angle using a flat knitting machine is not currently proposed.
The inventors of the present invention considered a knitting method of a knitted fabric
to knit a projecting knitted structure formed by bringing two stitches adjacent in
a knitting width direction closer in a direction of approaching each other to project
out to a surface of the knitted fabric. It was believed that, if the projecting knitted
structure could be knitted in the knitted fabric, a knitted fabric that appears differently
when seen from the left and when seen from the right should be obtained by having
the knitting yarn configuring one stitch in the projecting knitted structure and the
knitting yarn configuring the other stitch as different types.
[0005] In light of the foregoing, it is an object of the present invention to provide a
knitting method of a knitted fabric for knitting a projecting knitted structure formed
by bringing two stitches adjacent in a knitting width direction closer in a direction
approaching each other to project out to the surface side of the knitted fabric.
[0006] The present invention is a knitting method of a knitted fabric for knitting a knitted
fabric using a flat knitting machine including at least a pair of a front and a back
needle bed and in which one of the front and back needle beds is capable of being
racked in a traverse direction. The knitting method of the knitted fabric of the present
invention performs steps α and β from a state in which a stitch A
0 and a stitch Z
0 are held in order toward a right side on one of the needle beds and a stitch P
0 is held at a position between the stitch A
0 and the stitch Z
0 on the other needle bed.
[step α]... obtaining a state in which the position of the stitch P
0 is on a left side of the stitch A
0, and continuously performing knitting of a new stitch A
1 following the stitch A
0 and knitting of a new stitch P
1 following the stitch P
0. The stitch P
1 may be a tuck stitch.
[step β] ... obtaining a state in which a position of the stitch P
1 is on a right side of the stitch Z
0 and continuously performing knitting of a new stitch Z
1 following the stitch Z
0 and knitting of a new stitch P
2 following the stitch P
1. The stitch P
2 may be a tuck stitch.
The step α and the step β are performed to bring the stitch A
1 and the stitch Z
1 closer in a direction of approaching each other in a knitting width direction to
form a projecting knitted structure raised in a projecting form in a thickness direction
of the knitted fabric.
[0007] The step α and the step β are interchangeable, and when performing the step β first,
the stitch P
1 and the stitch P
2 in the step β are replaced with the stitch P
0 and the stitch P
1, and the stitch P
0 and the stitch P
1 in the step α are replaced with the stitch P1 and the stitch P
2 (see description below).
[step β] ... obtaining a state in which a position of the stitch P
0 is on a right side of the stitch Z
0 and continuously performing knitting of a new stitch Z
1 following the stitch Z
0 and knitting of a new stitch P
1 following the stitch P
0.
[step α]... obtaining a state in which the position of the stitch P
1 is on a left side of the stitch A
0, and continuously performing knitting of a new stitch A
1 following the stitch A
0 and knitting of a new stitch P
2 following the stitch P
1.
[0008] According to one aspect of the knitting method of the knitted fabric of the present
invention, the step α and the step β are performed from a state in which two or more
units, each unit having the stitch A
0 and the stitch Z
0 held on one needle bed and the stitch P
0 and a stitch Q
0 held on the other needle bed as one unit, are lined in the knitting width direction,
and the stitch Q
0 is at a position on a right side of the stitch P
0 and on the left side of the stitch Z
0. In this case, in the step β, the stitch Q
0 is positioned on the right side of the stitch Z
0 and the stitch P
2 is newly knitted following the stitch Q
0 (in this configuration, the stitches are not replaced even if the step β is performed
first; see second embodiment). Accordingly, the stitch A
1 of the unit on the right side and the stitch Z
1 of the unit on the left side are brought closer in the direction of approaching each
other in the knitting width direction to form the projecting knitted structure raised
in a projecting form in the thickness direction of the knitted fabric.
[0009] According to another aspect of the knitting method of the knitted fabric of the present
invention, a knitting yarn for knitting the stitch A
1 and the stitch P
1 and a knitting yarn for knitting the stitch Z
1 and the stitch P
2 are different types of knitting yarns. Of course, the knitting yarn for knitting
the stitch A
1 and the stitch P
1 and the knitting yarn for knitting the stitch Z
1 and the stitch P
2 may be the same type of knitting yarns.
[0010] According to another aspect of the knitting method of the knitted fabric of the present
invention, the projecting knitted structure is formed over the entire surface of the
knitted fabric.
[0011] A knitted fabric of the present invention is a knitted fabric knitted using a flat
knitting machine including at least a pair of a front and a back needle bed, and in
which one of the front and back needle beds is capable of being racked in a traverse
direction, the knitted fabric including a projecting knitted structure formed by bringing
a left side stitch and a right side stitch adjacent in a knitting width direction
closer in a direction of approaching each other in the knitting width direction. The
left side stitch is rotated in a clockwise direction with a wale direction as an axis
by having two cross-over yarns that are different in length and extending from the
left side stitch and connecting to the stitches arranged on a back side of the knitted
fabric. The right side stitch is rotated in a counterclockwise direction with the
wale direction as an axis by having two cross-over yarns that are different in length
and extending from the right side stitch and connecting to the stitches arranged on
the back side of the knitted fabric. The left side stitch and the right side stitch
lean against each other in a back to back state, and a portion on a boundary side
of the left side stitch and the right side stitch in the projecting knitted structure
projects out toward a surface side of the knitted fabric
[0012] According to the knitting method of the knitted fabric of the present invention,
the knitted fabric of the present invention including the projecting knitted structure
formed by bringing the stitch A
1 and the stitch Z
1 closer in a direction of approaching each other to project out to the surface of
the knitted fabric can be knitted. In the projecting knitted structure, the appearance
of when the knitted fabric is viewed from the left side and the appearance of when
the knitted fabric is viewed from the right side can be differed by having the knitting
yarn configuring the stitch A
1 and the knitting yarn configuring the stitch Z1 as different types of knitting yarns
(e.g., knitting yarn of different color, knitting yarn of different material, knitting
yarn of different thickness).
[0013] While the projecting knitted structure is invented in an aim of changing the appearance
of when viewed from the left side of the knitted fabric and the appearance of when
viewed from the right side of the knitted fabric, it also has a knitted structure
having a novel structure that has not been proposed in the past. Thus, even if the
type of the knitting yarn of the stitch A
1 and the type of the knitting yarn of the stitch Z
1 configuring the projecting knitted structure are not different, the projecting knitted
structure has a visual effect on the basis of such novel structure.
[0014] In the knitting method of the knitted fabric of the present invention, the projecting
knitted structure is formed over the entire surface of the knitted fabric to apply
the effect of the projecting knitted structure over the entire surface of the knitted
fabric. In particular, the iridescent colored knitted fabric in which the hue changes
depending on the viewing angle can be knitted by using different colors between the
knitting yarn of the stitch A
1 and the knitting yarn of the stitch Z
1 configuring the projecting knitted structure.
[0015] When the stitch Q
0 exists at the start of the step α, and the step β and the stitch P
2 is newly knitted following the stitch Q
0 in the step β, a thick projecting knitted structure can be obtained compared to when
the stitch Q
0 is not used. On the contrary, if the stitch Q
0 is not used, the number of stitches in the knitting width direction on the back side
of the knitted fabric (side opposite to the side in which the projecting knitted structure
projects out) is few compared to when the stitch Q
0 is used, and hence a thin projecting knitted structure can be obtained.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0017] An embodiment of a knitting method of a knitted fabric of the present invention will
be hereinafter described based on the drawings. In the embodiment, a knitting example
using a two-bed flat knitting machine including a front needle bed (hereinafter referred
to as "FB") and a back needle bed (hereinafter referred to as "BB") extending in a
traverse direction and disposed opposite to each other in a cross direction, and in
which the BB can be racked in the traverse direction will be described. The flat knitting
machine to be used is not, of course, limited to the two-bed flat knitting machine,
and may be a four-bed flat knitting machine.
<First embodiment>
[0018] In the first embodiment, an example of knitting a knitted fabric in which alphabets
stand out when the knitted fabric is seen from the left side as shown in Fig. 1(A)
and in which numbers stand out when the knitted fabric is seen from the right side
as shown in Fig. 1(B) will be described. In order to obtain such a knitted fabric,
a special knitted structure needs to be formed on the surface of the knitted fabric.
[0019] As shown in an enlarged photograph of Fig. 2, a projecting knitted structure 1 formed
by bringing two adjacent stitches (left side stitch 2, right side stitch 3) closer
in a direction of approaching each other is continuously arranged in plurals in a
wale direction and a course direction of the knitted fabric on the surface of the
knitted fabric of Fig. 1. The left side stitch 2 of the projecting knitted structure
1 contacts with the right side stitch 3 of the projecting knitted structure 1 in a
state of the left side stitch 2 rotating in a clockwise direction with a wale direction
as an axis and the right side stitch 3 rotating in a counterclockwise direction with
the wale direction as an axis, so that a portion on a boundary side of the stitches
2, 3 projects out at the surface of the knitted fabric. Looking at a cross-section
of the projecting knitted structure 1, the projecting knitted structure 1 is raised
in a substantially triangular shape to the surface side of the knitted fabric. Thus,
the left side stitch 2 can be seen more than the right side stitch 3 when the projecting
knitted structure 1 is seen from the left side, while the right side stitch 3 can
be seen more than the left side stitch 2 when the projecting knitted structure 1 is
seen from the right side. That is, a knitted fabric in which the pattern that can
be recognized differs in the right and left sides as shown in Fig. 1 can be knitted
by partially changing the color of the left side stitch 2 and the color of the right
side stitch 3 in the knitted fabric.
[0020] A knitting procedure of the projecting knitted structure 1 will now be described
based on a knitting step diagram of Fig. 3. "Alphabet + number" in Fig. 3 indicates
the number of the knitting step, a horizontal bar indicates a front needle bed (hereinafter
referred to as "FB") and a back needle bed (hereinafter referred to as "BB"), ○ indicates
a stitch held on the FB and the BB, and • indicates a newly formed stitch. The illustration
of a knitting needle arranged in the needle bed is omitted.
[0021] S1 of Fig. 3 shows a state in which the stitch A
0 and the stitch Z
0 are held in order toward the right side on the FB, and the stitch P
0 is held between the stitch A
0 and the stitch Z
0 in the BB. In S1, three units, each unit having the stitches A
0, Z
0, P
0 as one unit, are lined in a knitting width direction in a plane of drawing.
[0022] In S2, the BB is racked in the traverse direction to obtain a state in which the
stitch P
0 is positioned on the left side of the stitch A
0 (correspond to the first half of the step α). Furthermore, in S2, knitting of a new
stitch A
1 following the stitch A
0 and knitting of a new stitch P
1 following the stitch P
0 are continuously carried out (correspond to the second half of the step α). According
to S2, the stitch A
1 is knitted continuously in the wale direction of the stitch A
0, and the stitch P
1 is knitted continuously in the wale direction of the stitch P
0. In this case, a moving direction of a yarn feeder for supplying the knitting yarn
to the FB and the BB is not limited. For example, when performing S2, the yarn feeder
is moved toward the right side (left side) if the yarn feeder is on the left side
(right side) of the stitch A
0 and the stitch P
0 to knit the stitch P
1 (stitch A
1), and then the stitch A
1 (stitch P
1) is knitted following thereto. The stitch P
1 may be a tuck stitch. If the stitch P
1 is a tuck stitch, knitting is performed on the stitch P
1 with a knitting yarn different from the knitting yarn of the tuck stitch to fix the
tuck stitch before the next tuck knitting.
[0023] In S3, the BB is racked toward the right side, so that the stitch P
1 is positioned on the right side of the stitch Z
0 (correspond to the first half of the step β). Furthermore, in S3, the knitting of
a new stitch Z
1 following the stitch Z
0 and the knitting of a new stitch P
2 following the stitch P
1 are continuously carried out (correspond to the second half of the step β). According
to S3, the stitch P
2 is knitted continuously in the wale direction of the stitch P
1, and the stitch Z
1 is knitted continuously in the wale direction of the stitch Z
0. The moving direction of the yarn feeder in the step β is not limited. The moving
direction of the yarn feeder in S3 is determined merely by whether the yarn feeder
is on the left side or the right side of the stitch P
1 and the stitch Z
0 when performing S3. The stitch P
2 may be a tuck stitch. If the stitch P
2 is a tuck stitch, knitting is performed on the relevant tuck stitch before the next
tuck knitting to fix the tuck stitch.
[0024] S2 and S3 are thereafter repeated to form the next projecting knitted structure in
the wale direction of the projecting knitted structure. In the process of shifting
from nth (n is a natural number greater than or equal to 1) S3 to n+1th S2, the arrangement
of the stitches A
1, Z
1, P
2 in S3 becomes the same state as the stitches A
0, Z
0, P
0 in S1 (see S3'). That is, the nth stitches A
1, Z
1, P
2 can be assumed as the n+1th stitches A
0, Z
0, P
0.
[0025] In what state the stitches A
1, Z
1, P
2 formed in S3 are actually in the knitted fabric will be described based on Fig. 4.
Fig. 4 is a loop diagram simply showing the state of stitches in the cross-section
of the knitted fabric. In Fig. 4, the stitches are shown in a deformed manner so that
a deformed state of the stitches and the connection of the cross-over yarns between
the stitches can be recognized, and the vertical relationship of the knitting yarn
is ignored.
[0026] As shown in Fig. 4, the stitch A
1 of one unit is connected to the stitch P
1 of the same unit and the stitch P
1 of another unit adjacent on the right in the drawing with cross-over yarns, where
the former cross-over yarn is shorter than the latter cross-over yarn. As a result,
the stitch A
1 is rotated in the clockwise direction with the wale direction as the axis to get
closer to the stitch Z
1. The stitch Z
1 of one unit is connected to the stitch P
2 of the same unit and the stitch P
2 of another unit adjacent on the left in the drawing with cross-over yarns, where
the former cross-over yarn is shorter than the latter cross-over yarn. As a result,
the stitch Z
1 is rotated in the counterclockwise direction with the wale direction as the axis
to get closer to the stitch A
1. The stitch A
1 (the left side stitch 2) and the stitch Z
1 (the right side stitch 3) rotate in opposite directions to each other, and thus lean
against each other in a back to back state. As a result, the projecting knitted structure
1 configured by the stitches A
1, Z
1 projects out to the surface side of the knitted fabric.
[0027] When repeating the knitting steps described above, the knitted fabric shown in Fig.
1 can be knitted by changing the colors between the knitting yarn for knitting the
stitch A
1 and the stitch P
1 and the knitting yarn for knitting the stitch Z
1 and the stitch P
2 when forming the pattern in the knitted fabric. As apparent from Figs. 1(A) and 1(B),
the appearance of the knitted fabric changes depending on the viewing angle. Furthermore,
the knitted fabric has a line-shaped bump lined in the wale direction of the knitted
fabric, and thus has a unique appearance based on the bump. The projecting knitted
structure 1 is knitted using the front and back needle beds and is projected out to
the surface side of the knitted fabric, and thus the knitted fabric of the present
embodiment is thick but has high flexibility considering the thickness.
<Second Embodiment>
[0028] In the second embodiment, the arrangement state of the stitches before performing
the step α and the step β differs from the first embodiment, and the knitting procedure
of the knitted fabric in which the step β is performed before the step α will be described
based on Fig. 5. The way of viewing Fig. 5 is the same as the way of viewing Fig.
3.
[0029] T1 shows a state in which the stitch A
0 and the stitch Z
0 are held on the FB, and the stitch P
0 and the stitch Q
0 are held on the BB. The stitch Q
0 of the BB is arranged on the right side of the stitch P
0 and on the left side of the stitch Z
0 in the knitting width direction. In T1, two units, each unit having the stitches
A
0, Z
0, P
0, Q
0 as one unit, are lined in the knitting width direction in the drawing.
[0030] In T2, the BB is racked toward the right side so that the stitch Q
0 is positioned on the right side of the stitch Z
0, and the stitch Z
1 continuing in the wale direction of the stitch Z
0 and the stitch P
2 continuing in the wale direction of the stitch Q
0 are continuously knitted (correspond to the step β). The stitch P
2 may be a tuck stitch.
[0031] In T3, the BB is racked toward the left side so that the stitch P
0 is positioned on the left side of the stitch A
0, and the stitch A
1 continuing in the wale direction of the stitch A
0 and the stitch P
1 continuing in the wale direction of the stitch P
0 are continuously knitted (correspond to the step α). The stitch P
1 may be a tuck stitch.
[0032] T2 and T3 are thereafter repeated to form the next projecting knitted structure following
in the wale direction of the projecting knitted structure. In the process of shifting
from the nth T3 to the n+1th T2, the arrangement of the stitches A
1, Z
1, P
1, P
2 in T3 becomes the same state as the stitches A
0, Z
0, P
0, Q
0 in T1 (see T3'). That is, the nth stitches A
1, Z
1, P
1, P
2 can be assumed as the n+1th stitches A
0, Z
0, P
0, Q
0.
[0033] In what state the stitches A
1, Z
1, P
1, P
2 formed in T3 actually are in the knitted fabric will be described based on Fig. 6.
The way of viewing Fig. 6 is the same as the way of viewing Fig. 4.
[0034] As shown in Fig. 4, the stitch A
1 in a unit on the right side of the drawing is connected to the stitch P
1 of the same unit and the stitch P
1 of another unit adjacent on the left side of the drawing with cross-over yarns, where
the former cross-over yarn is shorter than the latter cross-over yarn. As a result,
the stitch A
1 of the unit on the right side is rotated in the counterclockwise direction with the
wale direction as the axis to get closer to the stitch Z
1 of the unit on the left side. The stitch Z
1 of one unit on the left side of the drawing is connected with the stitch P
2 of the same unit and the stitch P
2 of another unit adjacent on the right side of the drawing with cross-over yarns,
where the former cross-over yarn is shorter than the latter cross-over yarn. As a
result, the stitch Z
1 is rotated in the clockwise direction with the wale direction as the axis to get
closer to the stitch A
1 of the unit on the right side. The stitch Z
1 (left side stitch 2) and the stitch A
1 (right side stitch 3) rotate in opposite directions to each other, and thus lean
against each other in a back to back state. As a result, the projecting knitted structure
1 configured by the stitches A
1, Z
1 projects out to the surface side of the knitted fabric.
[0035] According to the knitting steps described above, a knitted fabric more stable than
the knitted fabric knitted with the knitting steps of the first embodiment is obtained.
This is because the number of stitches in the knitting width direction on the back
side of the knitted fabric of the second embodiment is greater than that of the first
embodiment.
[0036] A novel jacquard pattern that appears and disappears depending on the viewing angle
as shown in Fig. 1 can be formed as a visual pattern by partially changing the colors
and materials of the knitting yarns.
<Third Embodiment>
[0037] The color of the knitting yarn for knitting the left side stitch 2 and the color
of the knitting yarn for knitting the right side stitch 3 in Fig. 2 may be different
over the entire knitted fabric. For example, by knitting the knitted fabric with a
red knitting yarn for the left side stitch 2 and with a green knitting yarn for the
right side stitch 3, a knitted fabric in which color gradation forms at a portion
(a portion which is wrinkled, slacked, or curved along the human body) that curves
when the knitted fabric is worn can be obtained. The gradation forms because the proportion
the left side stitch 2 and the right side stitch 3 can be seen gradually changes according
to the degree of curve of the knitted fabric. Such knitted fabric is an iridescent
colored knitted fabric in which the hue partially changes in a complex manner depending
on the extent of wrinkles and slacks when worn.
[0038] The positions of the stitches were changed only using the racking of the needle bed
in the first to third embodiments, but the positions of the stitches may be changed
using the racking of the needle bed and the transferring of stitches.
