Composition and production methods of artificial hair (11) with natural organic material, comprising a core (12), surrounded by a mantle (9), whereby the core comprises a strong fiber with one or more filaments (13) and whereby the mantle comprises one or more layers of shellac and liquefied hydrolysed human hair, combined with crosslinkers that are attached to the core that can be composed of natural fibroin fibers or of fibers of a high performance synthetic polymer.

Provided is a strand extending in the longitudinal direction, wherein the strand includes filaments of one type having a gradient-length effect through spiral rotational twists and an irregular fine texture through self-thermal shrinking. The filaments of the strand have natural coiling characteristics that are very similar to those of natural hair of black people, and these characteristics are caused by the facts that the filaments have 3-dimensional waveforms occurred due to many fine and irregular windings or projections and that the waveforms exhibit fractal structure features and a fine kinky texture.

Provided is an artificial hair fiber which can prevent detachment between core and sheath, having superior texture close to human hair, and having superior curl retention. An artificial hair fiber has a core-sheath structure, including: a core; and a sheath covering the core; and: the core includes a core resin composition including polyester; the sheath includes a sheath resin composition including polyamide; the core and the sheath have a core/sheath mass ratio of 40/60 to 90/10; and when a melt viscosity of the polyester of the core is expressed as a, and a melt viscosity of the polyamide of the sheath is expressed as b, a viscosity ratio a/b is 0.5 to 2.5.

Provided are a strand which extends in one direction and includes 30 to 8,000 strands of thermoplastic polymer filaments including an amorphous organic polymer, a semi-crystalline organic polymer, or an alloy thereof, wherein each of the filaments has a fineness of 10 to 100 denier and the filaments are bonded to one another by surface fusion; and a method of preparing the same. Provided also are a weft using the strand, a wet look wig using the same, and a method of preparing the wig. When the strand is used, the filaments thereof may be bonded to one another through thermal surface-fusion using thermal properties of the filaments even without using a conventional water-soluble adhesive (binder), and thus a wet look wig washable with water even when worn by a user may be prepared by a simple and economical method.

A fiber bundle for artificial hair that has good curl setting characteristics, good combing property, tactile sensation and glossiness similar to human hair, and flame retardancy is provided. According to the present invention, provided is a fiber bundle for artificial hair is comprising 20 to 90 parts by mass of a polyester fiber and 10 to 80 parts by mass of a polyamide fiber, wherein the polyester fiber contains a polyester resin (A), a flame retardant (C1) and an auxiliary flame retardant (D1), and the polyamide fiber contains a polyamide resin (B), a flame retardant (C2) and an auxiliary flame retardant (D2).

The color-coded instructional wig system includes a wig cap configured to cover at least a portion of a scalp, wherein the wig cap includes an inner surface for contacting the scalp and an outer surface, a plurality of hair segments extending from the outer surface of the wig body, wherein each hair segment is a different color than the adjacent hair segment, and a style instruction including a plurality of steps for a user to perform to result in a final braided hair style.

For presenting the hair having a natural hair form when applied to the wig, there are provided a method of processing a hair for a wig, a method of manufacturing the wig and a manufactured wig, comprising: a cutting step of cutting a human hair that is a person's hair, in a predetermined length; an alignment step of expanding a plurality of cut human hairs and arraying the plurality of cut human hairs in a line; a fixing step of attaching and fixing the plurality of arrayed human hairs to a fixing pad so that the human hair is not detached; and a polishing step of polishing both longitudinal side portions of the human hair to make the side portions pointed using a polishing member including a polishing roller such that the side portions include tapered portions that are made thinner toward a tip of hair.

The present invention is an apparatus for head wear comprising a swimming cap portion that is breathable, and protects the hair and scalp of the user from water and other watery substance(s); and a wig portion that has the versatility/appearance of natural hair, and retains a desired style even after multiple use.

Protein fibers for artificial hair include a polycation, wherein the protein fibers for artificial hair are crosslinked with an organic compound and/or a metal salt, and the protein fibers for artificial hair have curls. A method for producing the protein fibers for artificial hair includes treating artificial protein fibers that are crosslinked with an organic compound and/or a metal salt with a treatment solution containing a polycation, and curling the artificial protein fibers, or curling artificial protein fibers that are crosslinked with an organic compound and/or a metal salt, and treating the curled artificial protein fibers with a treatment solution containing a polycation.

The present disclosure provides a flame retardant and antistatic regenerated polyester wig fiber and a preparation method thereof, and relates to the field of simulated wig technology. A composite flame retardant composed of poly(sulfonyldiphenylene phenylphosphonate) (PSPPP), a derivative of 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO-FT), and 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide triphosphonitrile (DOPO-TPN), and biomass-derived graphene are subjected to a re-polymerization reaction with an alcoholysis product BHET of a waste PET bottle flake, respectively to obtain an in-situ modified flame retardant regenerated masterbatch and an antistatic regenerated polyester masterbatch. The masterbatches are blended and melt-spun with regenerated polyester, so that the obtained wig fiber has good flame retardant property, better flame retardant coefficient and antistatic property, and a significant antibacterial effect, thereby increasing the safety of the wig. The recycled and regenerated polyester from the PET bottle is utilized, effectively reducing environmental pollution caused by waste polyester, and contributing to resource conservation and sustainable development.
