Preparation method of pine needle fibers

Abstract

The invention relates to a preparation method of pine needle fibers. The preparation method comprises the following steps of (1) preparing a pine needle extract solution; (2) performing swelling treatment on cationic viscose fibers; (3) preparing pine needle extract fibers; (4) spraying soft water; (5) spraying a softening agent; and (6) post-treatment. According to the preparation method of the fibers, firstly, the pine needle extract powder is uniformly dispersed in deionized water to prepare the pine needle extract solution, then the pine needle fiber is prepared in a spraying mode, no strong acid or strong base is involved in the process that the pine needle extract is adsorbed, high temperature is not needed, effective components in the pine needle extract cannot be damaged, the content of the pine needle extract in the prepared fiber is high, and the prepared composite fiber has good properties of expanding arterial blood vessels, increasing the oxygen carrying capacity of red blood cells, promoting blood circulation, improving capillary functions, improving immunity, increasing hormone secretion, strengthening essence and rejuvenating body tissues.

Description

technical field [0001] The invention belongs to the field of light industry textiles, and in particular relates to a preparation method of pine needle fibers. Background technique [0002] The textile industry is a traditional industry in China. With the rapid development of clothing, household and industrial textiles, the differentiation and individualization of textile products have become the focus of the development of various enterprises. Functional fibers as high-grade textile raw materials are generally improved by means of physical modification, chemical modification and molecular design to obtain fibers with specific properties, so that the original viscose fibers are stable in light and heat, conductive, Flame retardant, dyeing, antistatic, moisture absorption, fluffy, anti-pilling, anti-fouling and other aspects have been greatly improved. [0003] Regenerated cellulose fiber is made of natural cellulose (cotton, hemp, bamboo, tree, shrub) as raw material, withou...

Problems solved by technology

[0004] At present, most of the fibers with modified functions are added to the regenerated cellulose fibers by blending plant extracts. This process will inevitably come into contact with strong acid and strong alkali environments during the production process, which will damage the extracts and fibers. Cause damage and damage, and in the fiber forming process, the extract will be partially lost; through the way of injection before blending, the original color of the pine needle extract is not obvious, if too much is added, it will affect the fiber. spinnability, so that the prepared pine needle fiber has high defects, and the physical performance index of the fiber becomes worse
