Problems solved by technology

[0003] Due to the small moisture regain of corn fiber, it is easy to generate static electricity, which leads to hairiness in the spinning process. On the other hand, the cohesion of corn fiber is small, and it is easy to produce relative slippage during processing, resulting in accidental drafting of the sliver, resulting in easy spinning. Knots not only affect the spinnability of corn fiber, but also lead to poor yarn strength and wear resistance
The existing processing methods generally only make adaptive adjustments from the process and equipment, not only does not improve the spinnability much, but also the yarn quality is unstable and the difference between batches is large, which leads to poor yarn quality performance

Abstract

The invention relates to a corn fiber spinning process. The process comprises the following process steps of firstly, pretreating and mixing corn fiber, nano chitosan and water, then carrying out opening picking, cotton carding, drawing, roving, spinning and spooling processes, and meanwhile controlling the temperature and humidity conditions of a processing environment. Obtained corn fiber yarn has excellent spinning performance, and the strength and wear resistance of resultant yarn are enhanced.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a process for making corn fiber into yarn. Background technique [0002] The chemical name of corn fiber is polylactic acid fiber (abbreviated as PLA in English), which is a new type of eco-friendly fiber. Corn fiber is made from cornstarch through biodegradation and fermentation to obtain lactic acid, which is polymerized under appropriate conditions to produce high-purity polylactic acid, and then polylactic acid is used as raw material to spin into polylactic acid fiber. The raw material comes from renewable plant resources. Corn fiber has good biochemical decomposition performance, and can be decomposed into carbon dioxide and water by microorganisms in soil or water, without destroying resources and polluting the environment. It is in line with the direction of human sustainable development. It is of great significance to vigorously develop corn fiber and its textiles. [...
