Problems solved by technology

However, this method requires special devices in the production process, such as high voltage of more than 100,000 electron volts or the use of radioactive substances, which has hidden dangers for safe production. eclipse
[0008] CN101748600A discloses that the rabbit hair fiber is chemically treated with sodium dichloroisocyanurate, although this method improves the spinnability of the rabbit hair fiber, but due to the chemical treatment process, the integrity of the scales on the surface of the rabbit hair fiber is destroyed , causing rabbit hair fibers to break easily
[0010] The method in the above-mentioned patent has achieved certain results in solving the problem of poor cohesion of rabbit hair fibers, but it may not be applicable in actual production, or cause rabbit hair fibers to break easily, or reduce the natural color and luster of rabbit hair products. feel

Abstract

The invention provides a rabbit hair fiber processing method. The rabbit hair fiber processing method has the advantages that rabbit hair fibers are dyed after oxidation treatment, enzyme treatment and reduction treatment, so that the rabbit hair fibers are bright in color and luster, clear in grain, soft in hand feeling, high in elasticity, free from hair shedding and machine washable, cleaning and flattening effects on the rabbit hair fibers are achieved, intertwining of the rabbit hair fibers during spinning is reduced, high durability is achieved, and the rabbit hair fibers do not fade and discolor during long-term use.

Description

technical field [0001] The invention relates to the technical field of rabbit hair processing, in particular to a method for processing long-haired rabbit hair fibers. Background technique [0002] With the continuous development of our country's economy and the continuous improvement of living consumption ability, the people's requirements for clothing products are developing in the direction of "light, soft, warm, beautiful and dry", and rabbit fur clothing products all have the above advantages. The advantage of rabbit hair is that cotton, chemical fiber, and other animal hairs are incomparable. In particular, the fur of long-haired rabbits is not only thinner than the finest wool, clothing made of long-haired rabbits has strong moisture absorption capacity, light and soft, and is beautiful and generous. [0003] my country's long-haired rabbit breeds were first introduced in the 1980s from German Angora long-haired rabbits, French Angora long-haired rabbits, and Japanes...
