Abstract

The invention discloses a short flax fiber degumming and bleaching process. The process is characterized by taking short flax fibers as the processed objects and comprises the following steps in sequence: washing, alkali boiling, oxygen bleaching and cleaning. The process is mainly characterized by also comprising the steps of acid washing and sodium chlorite bleaching in sequence before the step of short flax fiber washing. The process has the following beneficial effects: not only does the process have good degumming and bleaching effects, but also the short flax fibers are characterized in that the short flax fibers can be used for spinning medium / high count yarns; and a simple and effective way is provided for utilization of the short flax spun fibers.

Description

technical field

[0001] The invention relates to a flax short fiber degumming and bleaching process, which belongs to the flax spinning raw material processing technology. Background technique

[0002] The short flax fiber in the present invention refers to the short flax fiber with a length of 50-70mm produced after the flax fiber is carded by a carding machine.

[0003] At present, the treatment methods of flax staple fiber mainly include mechanical method and chemical degumming method. The fibers processed by the mechanical method cannot remove the symbiosis such as pectin, lignin and hemicellulose of the flax fiber, so that the short fibers are thick, hard, and poor in spinnability and dyeability; the chemical degumming method is specifically processed The processing steps are: water washing→soda boiling→oxygen bleaching→cleaning. This method goes through a series of treatments. Although it can remove impurities such as fiber symbionts and hemp husks and hemp dust, this...
