What are the Basic Concepts and Codes of Chemical Fibres?

Basic Concepts of Chemical Fibres 1. Fibre Fiber is a long and thin substance with relative flexibility. The diameter of the typical textile fiber is from several microns to dozens of microns. The length is more than 25mm. The density is 10-5g/mm. For textile fibers, there should be a larger elongation at break, which is between 10%
