Cotton stalk bark fiber and method for processing cotton stalk bark

Abstract

Taught is a cotton stalk bark fiber. The fiber is a natural textile fiber made of cotton stalk balk. The length of the fiber is 5 mm-65 mm. The fineness thereof is 0.3-2.5 D. The intensity thereof is 0.284-0.432 N/tex. The breaking elongation rate thereof is 3%-6%. Taught is further a method for processing cotton stalk bark fiber comprising peeling, skimming, degumming, preserving, cutting, tanning, opening, carding, baking, boxing and classifying, and packaging. The invention provides an inexpensive natural fiber having wide applications in the textile industry. The fiber has a similar performance to bast fiber, higher intensity than cotton fiber, and may be blended with other natural fiber, man-made fibers and recycled fiber to form fiber yarn for various purposes. This method changes waste into a commodity, and brings about economic and social benefits.
