Definitions
- the present invention relates to a fiber-treating agent for imparting water resistance, heat resistance and heat shape memory ability to naturally derived fibers which are used for hair ornament products such as wigs and extensions.
- Naturally derived fibers examples include hair ornament products such as wigs and extensions.
- naturally derived fibers have natural texture and appearance originating from a natural material.
- regenerated protein fibers for example, regenerated collagen fibers are obtained by solubilizing acid-soluble collagen or insoluble collagen with an alkali or an enzyme to obtain a spinning stock solution, and discharging the spinning stock solution into a coagulation bath through a spinning nozzle to form fibers.
- regenerated collagen fibers generally have higher hydrophilicity and hence higher water absorption as compared to synthetic fibers, and the fibers have extremely low mechanical strength when they contain a large amount of water. This leads to deterioration of suitability as a hair ornament product such that during shampooing, mechanical strength significantly decreases because of the high water absorption, and during subsequent blowing with a hair drier, rupture occurs.
- Regenerated collagen fibers also have the problem of low heat resistance, so that if a set using a hair iron is performed at a temperature as high as that for human hair, shrinkage or crimping occurs, resulting in impairment of visual quality.
- plastic synthetic fibers the shape in a heat set with a hair iron or the like is continuously memorized even after subsequent hair washing (there is heat shape memory ability), whereas in regenerated collagen fibers, the shape in a heat set with a hair iron or the like is lost through subsequent hair washing (there is no heat shape memory ability). Therefore, regenerated collagen fibers are inferior to conventional plastic synthetic fibers in terms of degree of freedom of styling.
- Patent Literature 1 JP-A-2019-143281
- the present invention provides a fiber-treating agent comprising the following components (A) to (C) and having a turbidity of 1,000 NTU or less, wherein a part or all of the components (A) and (B) are optionally a condensate formed from the components:
- the present invention provides a method for treating fibers, comprising the following step (i):
- the present invention provides a method for producing fibers for hair ornament products, comprising a step of treating fibers by the method for treating fibers.
- the present invention provides a method for producing a hair ornament product, comprising a step of treating fibers by the method for treating fibers.
- the present invention provides a fiber for hair ornament products, comprising a condensate formed from the components (A) and (B).
- the present invention provides a hair ornament product having, as a constituent element, fibers comprising a condensate formed from the components (A) and (B).
- the present invention relates to a fiber-treating agent for producing fibers for hair ornament products in which the water resistance and the heat resistance of naturally derived fibers typified by regenerated collagen fibers are improved, heat shape memory ability is imparted, and the fibers are excellent in stretchability (tenacity).
- Patent Literature 1 when the fiber-treating agent disclosed in Patent Literature 1 is handled on the basis of the method for treating fibers in this document, a composition in which the fibers are immersed is changed through two-step phases. That is, in the phase 1, formaldehyde and a phenolic compound are present while reacting independently of each other, and in the phase 2, the formaldehyde and the phenolic compound grow while reacting with each other to form a condensation product, so that the turbidity of the composition increases.
- the present inventor found that when naturally derived fibers are brought into contact with the composition in the phase 2, a hard resin layer is formed on the surfaces of the fibers, and thus motions, such as bending and stretching, of the fibers are restricted, so that it is difficult to maintain the stretchability (tenacity) of the naturally derived fibers, and the feel of the fiber surfaces is deteriorated.
- the present inventor has further conducted studies on the basis of the above-described findings, and resultantly found that by treating naturally derived fibers with a composition containing formaldehyde and a specific phenolic compound and having a turbidity of 1,000 NTU or less while maintaining a state in which the turbidity of the treating agent is 1,000 NTU or less, not only the water resistance and the heat resistance of the naturally derived fibers are improved, so that heat shape memory ability can be imparted, but also surprisingly, the stretchability (tenacity) of the naturally derived fibers is improved as compared to that before the treatment, and can be enhanced to a level close to that of human hair, and the feel of the fiber surfaces can also be improved, leading to completion of the present invention.
- a fiber-treating agent for producing fibers for hair ornament products in which the water resistance and the heat resistance of naturally derived fibers are improved, heat shape memory ability is imparted, and stretchability (tenacity) is improved.
- Fibers to be treated with the fiber-treating agent of the present invention may be either synthetic fibers or naturally derived fibers, and are preferably naturally derived fibers.
- the naturally derived fiber refers to fibers which are taken from a natural animal or plant, or artificially produced using keratin, collagen, casein, soybeans, peanuts, corn, silk flocks, silk fibroin or the like as a raw material and which are used for production of a hair ornament product.
- fibers produced using keratin, collagen, casein, soybeans, peanuts, corn, silk flocks, silk fibroin or the like as a raw material are preferable
- regenerated protein fibers such as regenerated collagen fibers made from collagen as a raw material or regenerated silk fibers made from silk fibroin as a raw material are more preferable
- regenerated collagen fibers are further more preferable.
- Regenerated collagen fibers can be produced by a known technique, are not required to have a composition of collagen 100%, and may contain a natural or synthetic polymer and additives for improvement of quality.
- the regenerated collagen fibers may be post-processed.
- Regenerated collagen fibers are preferably in the form of filaments. Filaments are generally taken from fibers wound around a bobbin or packed in a box. It is also possible to directly use filaments coming out from a drying step in a production process of regenerated collagen fibers.
- formaldehyde as a component (A) and a phenolic compound as a component (B) may be contained as the compounds themselves, or may be contained with a part or all of the components (A) and (B) being a condensate formed from the components.
- the condensate may include water-soluble condensates having a small molecular weight, and water-insoluble condensates formed by linkage of the water-soluble condensates as long as the turbidity is 1,000 NTU or less.
- the condensate includes both water-soluble and water-insoluble condensates when referred to simply as a "condensate".
