Problems solved by technology

The traditional bast fiber mostly adopts chemical degumming, the degumming form is single, the production environment is poor, the labor intensity is high, and the pollution to the water area is serious, and because the degumming process is difficult to control, the degumming quality of the bast fiber is often unstable.

Abstract

The invention relates to a degumming method and a degumming device for bast fibers. The degumming method comprises the following steps of: mechanically degumming, biologically degumming and / or degumming through high-temperature cooking, sintering at high temperature, and distributing fiber and washing with water; and the degumming device comprises a mechanical degumming device, an inoculated fermentation device, a high-temperature liquid circulating device, a fiber distributing and water washing device and a yarn hanging device. The method and the device have the advantages of reasonable procedures, obvious degumming effect, good homogenization and consistence, high degumming operating efficiency, strong controllability, and neat bulk fiber processed. The invention can effectively reduce environmental pollution, so the invention can be widely applied to the degumming process of various bast fibers.

Description

technical field [0001] The invention relates to a degumming method and device, in particular to a bast fiber degumming method and device. Background technique [0002] Since the beginning of the 21st century, the various problems brought about by the development of modern industry at the cost of resource consumption and environmental problems have been widely concerned by human beings, and the sustainable development of society and the rational use of resources have been highly valued by countries all over the world. Since synthetic fibers produced from petroleum, coal, natural gas, etc. are non-renewable resources, they will eventually be exhausted. Therefore, renewable, recyclable, green and environmentally friendly renewable resources have attracted more and more attention. Bast fiber has unique functions such as antibacterial, health care, anti-ultraviolet radiation, moisture absorption, breathability, softness, and comfort. Therefore, research and development of bast fi...
