Problems solved by technology

Due to the poor cohesion and weak strength of the hemp fiber, in the spinning process, it is easy to cause uneven force in the drafting area of ​​the spinning frame, and the spun yarn is not fluffy after spinning, and the texture is relatively hard, which reduces the winding efficiency and affects the subsequent spun yarn dyeing. The end-break rate in the weaving process is reduced and the textile efficiency is reduced. Therefore, increasing the research on lubricants for processing flax or hemp roving will help to improve textile efficiency and promote the development of the hemp spinning industry

Abstract

The invention relates to the technical field of hemp textiles, in particular to a lubricant for treating hemp roving and a preparation method thereof. The lubricant is prepared from the following components in weight percent: tetraester group quaternary ammonium salt 3%-6 %; polyoxyethylene ether 8809 2%‑3%; silicone wax 6%‑9%; silane coupling agent KN‑550 3%‑5%; catalyst T‑50 2‑3%; D4 octamethylcyclotetrasilicon Oxygen 15%-20%; Glacial acetic acid 0.5%-1.5%; Deionized water balance. The preparation method of the lubricant is to weigh according to the proportion of the formula, adopt staged stirring, heating, and debugging to obtain the finished product. The invention improves the minimum strength of the roving, reduces the strong CV value, and makes the force in the drafting area of ​​the spinning frame more tend to be Even, the spun yarn is fluffy and soft after spinning, improves the winding efficiency, has no effect on the subsequent dyeing of the spun yarn, reduces the breakage rate in the weaving process, and effectively improves the textile efficiency.

Description

technical field [0001] The invention relates to the technical field of hemp spinning, in particular to a lubricant for treating hemp roving and a preparation method thereof. Background technique [0002] China is a big country of hemp textiles. The Yangtze River Delta and Pearl River Delta regions have become the world's most important flax production centers. Linen cloth is a fabric made of flax fiber. Various spinning processes into yarn. Hemp fibers for spinning include bast fibers and leaf fibers. Bast fibers include ramie, jute, kenaf, velvet, flax, hemp, etc. Leaf fiber has sisal, abaca and so on. Hemp fibers are rich in resources and have the characteristics of long fibers, small elongation, and fast moisture absorption and release. The spun yarns can be made into various hemp fabrics, hoses, conveyor belts, and various sewing hemp threads, etc., for clothing, decoration, It is widely used in industrial and agricultural production and national defense construction...
