Embodiment 1

[0052] A fiber with a single fineness of 65 dtex was obtained through the following steps in sequence: (a) 100 parts by mass of vinyl chloride resin (manufactured by Dayang Polyvinyl Chloride Co., Ltd., TH-1000, viscosity-average degree of polymerization 1000), polylactic acid resin (Unitika Co., Ltd., Terramac TE-4000, melting point 170°C) 50 parts by mass, hydrotalcite-based composite heat stabilizer (Nissan Chemical Industry Co., Ltd., CP-410A) 1 part by mass, ester-based lubricant (Riken Vitamin EW-100 (manufactured by the company) 0.75 parts by mass of the mixture is stirred using a Henschel mixer and heated up to 100°C to obtain a resin composition; (b) using a circular nozzle with a nozzle hole cross-sectional area of ​​0.05 mm 2 And a spinning die with 180 nozzle holes, and a 40mm single-screw extruder controlled at 175-185°C, melt-spun with a die temperature of 190°C and an extrusion rate of 15kg / hour to obtain an average fineness of 150 points The process of a speci...

Embodiment 2～10

[0054] Fibers were obtained in the same manner as in Example 1, using the blending amounts of the vinyl chloride-based resin and polyester-based resin shown in Table 1.

Embodiment 11

[0056] Fibers were obtained in the same manner as in Example 1, except that the vinyl chloride-based resin was changed to a vinyl chloride resin with a low degree of polymerization (TH-700, manufactured by Dayang Polyvinyl Chloride Co., Ltd., viscosity-average degree of polymerization: 700).

Abstract

Disclosed is a fiber made of a vinyl chloride resin, which is excellent in heat resistance and thus hardly shrinks thermally even at a temperature higher than 100 DEG C. Specifically disclosed is a fiber obtained by melt-spinning a resin composition containing a vinyl chloride resin and 1-300 parts by mass of a polyester resin per 100 parts by mass of the vinyl chloride resin. The vinyl chloride resin has a viscosity-average polymerization degree of 600-2500. The polyester resin is composed of a polylactic acid resin, and has a melting point of 100-300 DEG C.

Description

technical field [0001] The present invention relates to a vinyl chloride-based resin fiber having excellent heat resistance, which is less heat-shrinkable, and a method for producing the same. Background technique [0002] Conventionally, vinyl chloride-based resins have been used as typical general-purpose plastics for various applications because they are excellent in weather resistance, transparency, flame retardancy, and chemical resistance, and are inexpensive. Since the fiber is close to natural hair in strength, extensibility, touch, etc., it is often used as a fiber for artificial hair such as hair wigs and doll hair, for example. [0003] However, in order to make it more similar to natural hair, various fiber secondary processing is performed, but as a result, there is a problem that heat shrinks more than necessary in the processing process of hair wigs and the like. As a method to solve it, a vinyl chloride-based fiber composed of a vinyl chloride resin and a ch...
