Problems solved by technology

[0003] In addition, my country is a big peppermint producer in the world. For a long time, the peppermint industry as an agricultural product has only entered the market with primary products such as peppermint oil. On the one hand, the price is low and the economic benefits are not high. At the bottom, the market price fluctuates greatly, which is not conducive to the stable development of the mint industry

Abstract

The invention provides a preparation method of flax-viscose-mint heat-insulating fiber. The preparation method comprises the following steps: dipping flax pulp, and carrying out pressing and smashing to obtain alkali cellulose, wherein the average degree of polymerization of the flax pulp is 400 to 450; yellowing the alkali cellulose, adding a bamboo charcoal-mint emulsion and phase change microcapsules, and carrying out dissolving and filtering to obtain a spinning solution; spinning with the spinning solution to obtain the flax-viscose-mint heat-insulating fiber. As the bamboo charcoal-mint emulsion and the phase change microcapsules are added after yellowing, the performance of the flax-viscose-mint heat-insulating fiber can be improved; moreover, as bamboo charcoal and mint have a health-care function and a refreshing fragrance, and the microcapsules can be used for remaining the refreshing fragrance, a sock made of the flax-viscose-mint heat-insulating fiber can be endowed with a health function, and can perform a cool and comfortable effect all the time when being worn by a user.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a preparation method of hemp viscose mint thermal insulation fiber and socks. Background technique [0002] Viscose fiber has a long history. As early as the end of the 19th century, British scientists Cross, Bevan, and Beadle invented the method for preparing cellulose sulfonate. For more than 100 years, viscose fiber raw material natural cellulose has a wide range of sources and is a renewable resource. The product has good wearing performance, and has a series of advantages such as moisture absorption, breathability, softness, easy dyeing, and antistatic, making it very comfortable to wear; moreover, viscose fiber can be degraded naturally and will not cause environmental pollution. Hemp viscose fiber is a viscose fiber obtained from hemp pulp. It has become a research hotspot due to its light texture, soft luster, antibacterial and antibacterial properties. [0003] In addition, my ...
