Example

Example 1

[0127]First, 100 parts by mass of a nylon 6 resin (1013B, manufactured by UBE INDUSTRIES, LTD.) and 5 parts by mass of crosslinked acryl particles (MXB-2B, manufactured by SEKISUI CHEMICAL CO. LTD.) were blended with a hand. Then, the mixture was subjected to melt-spinning by using a spinning spinneret having a round nozzle shape, a nozzle cross sectional area of 0.2 mm2, and a hole number of 20, at a cylinder temperature of 280° C. and at an extrusion amount of 1.0 kg / hour. After that, the fibers were stretched to 300% under an atmosphere of air at 100° C., and were subjected to thermal relaxing treatment under an atmosphere of air at 150° C. to yield polyamide fibers having a fineness of monofilament and a flexural rigidity value as shown in Table 1.

Example 2

[0128]First, 100 parts by mass of a vinyl chloride resin (TH-1000, manufactured by TAIYO VINYL CORP.), 3 parts by mass of a hydrotalcite type composite stabilizer (CP-410A, manufactured by Nissan Chemical Industries, Ltd.) (the thermal stabilizer component had 1.5 parts by mass), 0.5 parts by mass of an epoxidized soybean oil (O-130P, manufactured by Asahi Denka Kogyo K. K.), and 0.8 parts by mass of an ester lubricant (EW-100, manufactured by Riken Vitamin Co., Ltd.) were formulated into a vinyl chloride resin composition. Then, the composition was subjected to melt-spinning by using a spinning spinneret having a round nozzle shape, a nozzle cross sectional area of 0.06 mm2, and a hole number of 120, at a cylinder temperature of 180° C. and at an extrusion amount of 10 kg / hour. After that, the fibers were stretched to 300% under an atmosphere of air at 100° C., and were subjected to thermal relaxing treatment under an atmosphere of air at 120° C. until the entire length of...

Comparative Example 1, Comparative Example 2

[0129]A fiber bundle for artificial hair was obtained in the same manner as in Example 1 except that the flexural rigidity and the fineness of monofilament as shown in Table 1 were achieved using melt-spinning by changing the nozzle shape to an elliptical shape in Comparative Example 1 and by changing the nozzle shape to an H-shape in Comparative Example 2.

Abstract

The present invention provides an artificial hair fiber having a good balance between a feel and a curly characteristic. The present invention also provides an artificial hair fiber having a better hackling efficiency and weaving efficiency, a fiber bundle for artificial hair, and a process for producing the same. Artificial hair fibers possess desired properties, the fibers having a flexural rigidity of from 0.001 to 0.01 gf·cm2 or being subjected to crimping in which a crimp wave shape satisfies the following formulae: 0.2 mm≦R≦3 mm, 1 mm≦L≦15 mm, (wherein R is a length from the top to the bottom of a crimp wave shape), and (wherein L is a length between the tops (or between the bottoms) of a crimp wave shape).

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a National Phase of PCT International Patent Application No PCT / JP2010 / 055266, filed Mar. 25, 2010, and Japanese Patent Application No 2009-100448 filed Apr. 17, 2009, in the Japanese Patent Office, the disclosures of which are incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to artificial hair fibers used for a hair decoration[0004]2. Description of the Related Art[0005]As an artificial hair fiber, a variety of fibers are commercially available, including a polyvinyl chloride fiber, a polyamide fiber, a polyester fiber, and the like. The fibers are properly used depending on their style or use.[0006]Research has been conducted that allows an artificial hair fiber to approach a texture of natural hair or that imparts superior performance than that of the natural hair to the artificial hair fiber. Examples of evaluation items for the artificia...
