[Industrial Application Field] The present invention relates to a method for epoxidizing animal fiber materials. To explain in more detail,
The present invention provides an epoxidation treatment method that can protect the epidermal tissue of a material containing animal fibers having scale in the epidermal tissue and impart shrink-proofing properties to the material without reducing its water repellency or mechanical strength. It is related to. [Prior Art] Generally, the cause of animal fibers becoming felt is not simple and involves various factors, but the main factor is anisotropy in the coefficient of friction caused by the form of scale-like scales present on the surface of animal fibers. Something is well known. In other words, the larger the difference between the coefficient of friction μ 1 of the animal fiber in the direction toward the hair tip and the coefficient of friction μ 2 in the direction toward the hair root, the more easily the animal fiber becomes felt. For this reason, in the shrink-proofing of animal fibers, it is generally difficult to make the above-mentioned μ 1 and μ 2 equal. Generally, the degree of shrink-proofing is expressed by the anisotropy of friction coefficient (DFE) defined as below. DFE = μ 2 − μ 1 / μ 2 + μ 1 Another principle method for shrink-proofing animal fiber materials is to align all the fibers in a certain direction (hair root → hair tip) to produce a product, such as in sheepskin. It is known that by doing this, the resulting product will not become felt. However, in animal fiber materials, the fiber direction becomes random during the spinning process, for example, so it is extremely difficult to implement the above method. Therefore, at present, a practical method for shrink-proofing animal fiber materials is to eliminate the anisotropy of the coefficient of friction on the fiber surface. As such shrink prevention methods, those listed in Table 1 are known.

法。[Scope of Claims] 1. A material containing animal fibers is treated with a first stage treatment bath consisting of a saturated aqueous solution of a substantially neutral inorganic salt to remove the epidermal tissue of the animal fibers without swelling them. Then, a second stage treatment bath prepared by adding an inorganic reducing agent consisting of at least one selected from acidic sodium sulfite, sodium sulfite, and sodium thiosulfate to the first stage treatment bath, The moistened epidermal tissue of the animal fibers is subjected to a reduction treatment, and then a third-stage treatment solution prepared by adding a polyfunctional epoxy compound to the second-stage treatment bath is used to reduce the epidermis of the reduced animal fibers. A method for epoxidizing animal fiber materials, comprising: subjecting tissue to a cross-linking polymerization treatment.
