Processing agents and methods for synthetic fibers

Description

Background of the Invention

[0001] This invention relates to agents for the processing of synthetic fibers and methods of processing synthetic fibers.

[0002] With the recent increase in the speed of spinning and fabrication processes for synthetic fibers, occurrence of fluffs and breaking in produced yarns, as well as uneven dyeing of the fabric is becoming even more frequent. In order to prevent such occurrence of fluffs, yarn breaking and uneven dyeing, it has been known to increase the content of a functional improvement agent serving as a processing agent for the synthetic fibers to be applied thereto or to increase the amount of such a processing agent to be applied but such prior art attempts have not been sufficient in view of the recent increase in the speed. It is therefore an object of this invention to provide improved processing agents and methods for synthetic fibers capable of sufficiently preventing the occurrence of fluffs, yarn breaking and uneven dyeing.

[0003] It has been known to use processing agents containing a lubricant and a functional improvement agent for synthetic fibers. Known examples of processing agents containing a functional improvement agent for preventing the occurrence of fluffs, yarn breaking and uneven dyeing include those described in Japanese Patent Publications. Tokkai 1-298281, 2-47372, 60-181368, 2000-136448, 60-9971, 1-306684, 2-269878 and 62-85076 and US patents 6,432, 144B1 and 5,472,623A. These processing agents are not sufficiently capable of the occurence of fluffs, yarn breaking and uneven dyeing in view of the requirement of the recent years due to increased processing speed.

[0004] EP 0 953 673 discloses a method of processing synthetic fibers which are subjected to a heat treatment. The method comprises the step of applying an agent containing a polyether compound, a straight-chain polyether modified polyorganosiloxane compound of a specified kind, and an ionic surfactant to the synthetic fibers.

[0005] JP 02 269878 discloses a method of processing polyester fibers comprising the application of an agent comprising: a polyether compound obtained from propylene oxide and ethylene oxide in a specified ratio and a monohydric alcohol of specified molecular weight; a mixture of specified anionic surfactants; and a polyoxyethylene/polyoxypropylene-modified silicone.

Part 2

Attachment of processing agent onto synthetic fibers

[0055] Each of the processing agents prepared in Part 1 was diluted with water to prepare a 10% aqueous solution. After polyethylene terephthalate chips with intrinsic viscosity of 0.64 and containing titanium oxide by 0.2% were dried by a known method, they were spun at 295°C by using an extruder. The 10% aqueous solution thus prepared was applied onto the yarns extruded out of the nozzle to be cooled and solidified by a guide oiling method using a measuring pump such that the attached amount of the processing agent became as shown in Tables 8 and 9. Thereafter, the yarns were collected by means of a guide and wound up at the rate of 3000m/minute without any drawing by a mechanical means to obtain partially drawn 128 decitex-36 filament yarns as wound cakes of 10kg.

False twisting

[0056] The cakes thus obtained as described above were subjected to a false twisting process under the conditions described below by using a false twister of the contact heater type (product name of SDS1200 produced by Teijinseiki Co., Ltd.):

Fabrication speeds:

800m/minute and 1200m/minute;

Draw ratio:

1.652;

Twisting system:

Three-axis disk friction method (with one guide disk on the inlet side, one guide disk on the outlet side and four hard polyurethane disks);

Heater on twisting

side: Length of 2.5m with surface temperature of 210°C;

Heater on untwisting

side; None;

Target number of

twisting; 3300T/m.

The false twisting process was carried out under the conditions given above by a continuous operation of 25 days.

Evaluation of fluffs

[0057] In the aforementioned false twisting process, the number of fluffs per hour was measured by means of a fly counter (product name of DT-105 produced by Toray Engineering Co., Ltd.) before the false twisted yarns were wound up and evaluated according to the standards as described below:

AAA: The measured number of fluffs was zero;

AA: The measured number of fluffs was less than 1 (exclusive of zero);

A: The measured number of fluffs was 1-2;

B: The measured number of fluffs was 3-9;

C: The measured number of fluffs was 10 or greater.

The results of the measurement are shown in Tables 10 and 11.

Evaluation of yarn breaking

[0058] The number of occurrences of yarn breaking during the 25 days of operation in the false twisting process described above was converted into the number per day and such converted numbers were evaluated according to the standards as described below:

AAA: The number of occurrence was zero;

AA: The number of occurrence was less than 0.5 (exclusive of zero);

A: The number of occurrence was 0.5 or greater and less than 1;

B: The number of occurrence was 1 or greater and less than 5;

C: The number of occurrence was 5 or greater.

The results are shown in -Tables 10 and 11.

Dyeing property

[0059] A fabric with diameter of 70mm and length of 1.2mm was produced from the false-twisted yarns on which fluffs were measured as above by using a knitting machine for tubular fabric. The fabric thus produced was dyed by a high temperature and high pressure dyeing method by using disperse dyes (product name of Kayalon Polyester Blue-EBL-E produced by Nippon Kayaku Co. Ltd.). The dyed fabrics were washed with water, subjected to a reduction clearing process and dried according to a known routine and were thereafter set on an iron cylinder with diameter 70mm and length 1m. An inspection process for visually counting the number of points of densely dyed potion on the fabric surface was repeated five times and the evaluation results thus obtained were converted into the number of points per sheet of fabric. The evaluation was carried out according to the following standards:

AAA: There was no densely dyed portion;

AA: There was 1 point of densely dyed portion;

A: There were 2 points of densely dyed portion;

B: There were 3-6 points of densely dyed portion;

C: There were 7 or more points of densely dyed portion.

The results are shown in Tables 10 and 11.

[0060] From the results shown in Tables 10 and 11, it should be clear that the present invention has the favorable effects of sufficiently preventing the occurrence of fluffs, yard breaking and uneven dyeing although the speed of the spinning and fabrication processes of synthetic fibers is increased in recent years.
