Description

Fiber treatment agent Technical Field The present invention relates to a fiber treatment agent. Background Natural source fibers generally differ from synthetic fibers in that they have a natural hand and appearance derived from natural materials. The regenerated protein fibers, for example, regenerated collagen fibers, among the natural source fibers are usually produced by dissolving acid-soluble collagen or insoluble collagen with alkali or an enzyme to prepare a spinning dope, discharging the spinning dope from a spinning nozzle into a coagulation bath to carry out fiberization, and then drying the fibrous collagen in a final step. However, natural fibers are generally hydrophilic and therefore have a high water absorption rate as compared with synthetic fibers, and in a state where they contain a large amount of water, the mechanical strength is generally low, and in particular, the mechanical strength of regenerated protein fibers is extremely low. Therefore, the mechanical strength is significantly reduced due to high water absorption during cleaning, and breakage or the like occurs at the time of drying with a blower thereafter, resulting in reduced applicability as a headwear product. In addition, the regenerated protein fiber has a problem of low heat resistance, for example, shrinkage or curling occurs when shaping is performed at the same high temperature as human hair in heat shaping using a hair iron or the like, and aesthetic properties are impaired. Further, although the synthetic fiber made of plastic can keep its shape (has thermal shape memory ability) even after washing by a hair iron or the like when heat-setting is performed, the natural fiber has a disadvantage in that the shape disappears (does not have thermal shape memory ability) in one washing after heat-setting by a hair iron or the like, and thus there is a disadvantage in view of the degree of freedom of molding compared with the conventional synthetic fiber made of plastic. These problems have been a factor that has prevented the popularization of fibers of natural origin, particularly regenerated protein fibers, in fiber products such as head gear products. Accordingly, various studies have been made to solve the above-mentioned problems of the natural source fibers. For example, it has been reported that, in a fabric containing at least 10 wt% of wool, the wool is crosslinked by an acrylic resin, whereby loss (fuzzing) due to friction at the time of washing can be suppressed (patent document 1). It has also been reported that the above-mentioned problems regarding water resistance, heat resistance and thermal shape memory ability, which are specific to natural source fibers, can be solved by treating natural source fibers with a fiber treatment agent containing a specific methylol compound and a specific phenol compound (patent document 2).
