The utilization of special animal fibers including cashmere,yak hair,camel hair,rabbit hair and feathers is illustrated by literature and the archaeological discoveries.

It specifically states the technological features of polypropylene fibers,polyester fibers,specialty polymer fibers,fluoropolymer fibers as well as polymeric nanofibers and their application status in the filtration area.

So the development characteristics of fibers used in non-woven are analized,especially focusing on the features of some special fibers and its application in non-woven industry.

This article introduces the properties of some special fibers such as inorganic fiber,organic fiber and metal fiber etc.

The company concentrated from an early date on the manufacture of specialty fibers that means fibers which are unique, they have unusual properties and fulfill more far-reaching and different functions than standard fibers.

Research on the development and application of n“非汉字符号”--A new kind of animal fibers;

Bleaching of pigmented wool and special animal fibers;

Several kind of animal fiber's shape structure and distinguishes

Based on the principle of twice image formation of scanning electron microscopy(SEM),the scale thickness,ratio of diameter to height,scale density of special animal fibers and wool fiber are determined.
