Problems solved by technology

In this method, although an acrylic fiber having an animal hair-like feel can be obtained through one-step treatment, especially in fibers with a thin fineness or a special-shaped cross-section that tends to generate static electricity, the processability such as entanglement in the spinning process is poor.

Embodiment 1

[0074] A polymer obtained by copolymerizing 90% of acrylonitrile, 9.8% of methyl acrylate and 0.2% of sodium methallylsulfonate (intrinsic viscosity [η] in dimethylformamide at 30°C: 1.4) was dissolved in 50 % concentration of sodium thiocyanate aqueous solution, the production of polymer concentration of 12% of the spinning stock solution, the use of circular nozzle hole shape, the spinning in -3 ℃, 15% sodium thiocyanate aqueous solution The stock solution is spun, and washed, stretched, heat-treated, etc. are carried out according to conventional methods to prepare fiber tow.

[0075]Next, dilute the fiber treatment agent A described in Table 1 so that the total component concentration (total solid content) is 1.2% by weight, and after dipping the fiber tow in the diluted treatment agent, carry out tie-dyeing so that the adhesion amount of the treatment agent 50% relative to the dry weight of the fiber, then dried under hot air at 125°C for 15 minutes, cut into lengths rang...

Embodiment 2

[0078] Except having used the processing agent B-G for fibers described in Table 1, it carried out similarly to Example 1, and produced the fiber sample (2-7). These evaluation results are described together in Table 1.

[0079] It is clear from Table 2 that among fiber Nos. 1 to 4, 6 and 7 using the fiber treating agent used in the present invention, fiber Nos. 4 and 7 are excellent in both hand feeling and spinnability. Fiber No. 1, 2, 3 and 6 with slightly less amino-modified polyorganosiloxane had slightly poorer smoothness, and fiber No. 3 without added spinning oil had slightly poorer spinnability, but it could be used in used in practice. On the other hand, fiber No. 5 using a treatment agent that does not contain an imidazolium salt compound or a fatty amide contained a large amount of amino-modified polyorganosiloxane, and although it was excellent in smoothness, entanglement and the like occurred during spinning. Spinnability is poor.

Embodiment 3

[0081] A polymer obtained by copolymerizing 90% of acrylonitrile, 9.8% of methyl acrylate and 0.2% of sodium methallylsulfonate (intrinsic viscosity [η] in dimethylformamide at 30°C: 1.4) was dissolved in 50 % concentration of sodium thiocyanate aqueous solution, the production of polymer concentration of 12% of the spinning stock solution, the use of circular nozzle hole shape, the spinning in -3 ℃, 15% sodium thiocyanate aqueous solution The stock solution is spun, and washed, stretched, heat-treated, etc. are carried out according to conventional methods to prepare fiber tow.

[0082] Next, dilute the fiber treatment agent F described in Table 1 so that the total component concentration (total solid content) is 1.2% by weight, and after dipping the fiber tow in the diluted treatment agent, carry out tie-dyeing so that the adhesion amount of the treatment agent is relatively The dry weight of the fiber was 50%, followed by drying under hot air at 125° C. for 20 minutes, and ...

Abstract

The present invention provides an acrylonitrile fiber which is excellent in processability and has a smooth feel like animal hair. The acrylonitrile fiber is characterized in that it contains 2-12% by weight of a specific imidazolium salt compound, 10-35% by weight of a specific fatty amide derivative, and 10-50% by weight of a specific amino-modified polyorganosiloxane and 8 to 25% by weight of nonionic surfactants, and a fiber treatment agent containing a total of 40% by weight or more of these substances, relative to the dry weight of the fiber, 0.1 to 2.0% by weight of the total solid content of the fiber treatment agent is attached %.

Description

technical field [0001] The present invention relates to an acrylonitrile fiber having a smooth feel like animal hair and excellent processability. technical background [0002] It is well known that knitted fabrics made of animal hair fibers such as wool, cashmere, and angora fur have an excellent handle based on a unique smooth feel, and even synthetic fibers such as acrylic fibers have been proposed to impart a unique feel to the animal hair fiber. As this method, it is proposed to add an amino-modified organopolysiloxane to acrylic synthetic fibers in a gel-swollen state in an emulsion state of a specific composition, dry and densify them, and then add a spinning oil. method (Patent Document 1). In addition, it is proposed to mix and stir an emulsifier selected from POE=(n') alkylphenyl phosphate with a specific silicone resin, and add water at the same time to form a weakly acidic emulsion. A method in which the obtained swollen gel-like acrylic fiber is dried immediat...
