Problems solved by technology

Therefore, there is a problem that the orientation of the fibers is uniform on the curved surface, and the glossy feeling tends to become unnatural, and it is difficult to express a three-dimensional effect when the roll is provided. The dense feeling of the cross-sectional shape of the fibers proposed in Patent Documents 2 and 3 is improved, but Cracks and broken wires are prone to occur due to external force, and the durability is unsatisfactory

Embodiment 1

[0089] Polyterephthalate containing 2.5% by mass of aggregated silica particles (average particle size: 2.43 μm) and an intrinsic viscosity (measured at 25°C in a 1:1 mixed solvent of phenol and tetrachloroethane) of 0.97 The ethylene glycol formate chips were dried in vacuo at 165°C for 9 hours. The chips were supplied to an extrusion-type spinning machine at 285° C., and the heated and melted resin composition was obtained from figure 1 (a) Extruded through a 3-lobe nozzle with the cross-sectional shape of the filament, immediately cooled in 30°C water, then stretched to 4.1 times in warm water at 55°C and dry heat at 100°C, and then relaxed in a dry heat atmosphere heat treatment.

[0090] Next, as an alkali treatment, the coiled monofilament was immersed in a sodium hydroxide solution, the surface of the wool material was dissolved, washed with water, and dried to obtain a straight polyester monofilament.

[0091] The polyester monofilament was dyed black by a convention...

Embodiment 2

[0094] Using polyethylene terephthalate chips containing 1.5% by mass of colloidal silica (Syrisia 730 manufactured by Fuji Silisia Chemical Co., Ltd.) and having an intrinsic viscosity of 1.10, the extrusion nozzle was changed to correspond to figure 1 A straight monofilament for artificial hair was obtained in the same manner as in Example 1 except for the three-leaf nozzle having the filament cross-sectional shape in (c).

[0095] Table 1 shows the properties of the obtained filament for artificial hair.

Embodiment 3、4

[0096] [Examples 3 and 4, Comparative Examples 1 to 3]

[0097] Straight monofilaments for artificial hair were obtained in the same manner as in Example 2 except that the extrusion nozzle was changed to one corresponding to each shape shown in Table 1.

[0098] Table 1 shows the properties of the obtained filament for artificial hair.

[0099] [Table 1]

[0100]

[0101] From Table 1, it was confirmed that the filaments for artificial hair according to the examples of the present invention are excellent in volume and luster, and are less prone to tearing and breaking.

[0102] On the other hand, the filaments for artificial hair (Comparative Examples 1 to 3) having a cross-sectional shape that does not satisfy the conditions of the present invention not only have an unnatural sense of volume and luster, but are also prone to tearing and breaking, and are not suitable for use as artificial hair. Use filament.

Abstract

The invention addresses the issue of providing a filament for artificial hair, that has an excellent feeling of volume and glossiness and has little thread splitting or breakage. This thermoplastic resin filament has a cross-sectional shape in a direction orthogonal to the fiber shaft that is a multi-leaf shape having at least three delamination sections. The width (W2) of the delamination sections is 10%-60% of the width (W1) of the filament and the depth (H2) of the delamination sections is 5%-30% of the height (H1) of the filament.

Description

technical field [0001] The present invention relates to false headgear ( ),wig( ) or fibers for artificial hair used in hair extensions, etc. Background technique [0002] Conventionally, modacrylic fibers, vinyl chloride fibers, vinylidene chloride fibers, polyester fibers, nylon fibers, and the like have been used as fibers for artificial hair. When using these fibers to produce artificial hair products such as wigs, wigs, and hair extensions, we have repeatedly developed fibers suitable for these products, and have repeatedly studied and improved the cross-sectional shape of the fibers. [0003] For example, fibers for artificial hair having a concavity-shaped cross-sectional shape such as a cocoon shape and a glasses shape have been proposed (for example, refer to Patent Document 1). [0004] Fibers with a Y-shaped cross-section (for example, see Patent Document 2), fibers with a rounded Y-shaped cross-section (for example, see Patent Document 3), and the like have ...
