What is chemical fiber? How to detect?- Xinghui Chemical Fiber Group Co., Ltd.

The full name of chemical fiber is chemical fiber, which refers to the fiber made from natural or synthetic polymer materials. According to the different source of raw materials, it can be divided into man-made fiber with natural polymer material as raw material and synthetic fiber with synthetic polymer material as raw material.

The preparation of chemical fiber is usually made of natural or synthetic polymer materials or inorganic materials into spinning melt or solution, and then filtered, measured, extruded into liquid stream by the spinneret (plate), and then solidified into fiber. Right NOW THE FIBER IS CALLED PRIMARY fiber, ITS mechanical properties are very poor, MUST PASS A SERIES OF after PROCESSING WORKING PROCEDURE ABILITY ACCORDS WITH TEXTILE PROCESSING AND USE REQUIREMENT. Post-processing is mainly aimed at fiber stretching and heat shaping to improve the mechanical properties and dimensional stability of the fiber. Stretching is to Orient macromolecules or structural units in the primary fiber along the fiber axis. Heat setting is mainly to relax the internal stress in the fiber.

The post-processing of wet spinning fiber also includes washing, oiling, drying and other processes. When spinning filament, it can be wound into a barrel by the above procedure; It is necessary to add crimping, cutting and packing when spinning short fiber. Today, 100 check network for you to introduce the knowledge of the relevant detection. Baijian network to provide authoritative and effective testing reports, the main business scope includes food, agricultural products, environmental soil, environmental protection and industry standard training, retailer services, etc., to provide you with convenient testing services. You can contact us if you need anything.

Its testing items include

Composition analysis: chemical fiber composition identification, chemical fiber chemical composition, quantitative chemical analysis, qualitative chemical analysis, etc.

Physical and chemical indexes: fiber birefringence, melting point, solubility, purity, oil content, density gradient, etc.

Flame retardant performance: combustion performance, combustion grade, flame retardant performance, etc.

Electrical properties: anti - static, conductive properties, etc.
