Embodiment

[0017] The specific implementation steps are as follows:

[0018] a) Preparation of warp yarn and weft yarn: cotton fiber and hemp fiber are selected as raw materials for warp yarn and weft yarn. Before spinning, the hemp fiber is pre-combed to remove some thick fibers and improve the yarn quality, and then add a certain amount of softener to the hemp for health treatment to improve its spinnability, the amount of softener It’s enough to just cover the hemp. Cotton / hemp is spun by vortex spinning at a ratio of 65:35, and the fineness of both warp and weft is 14.8tex.

[0019] b) Dyeing: The dyeing process mainly includes: pretreatment, dyeing, color fixing and drying. Among them, the pretreatment process adopts low-alkali high-temperature oxygen bleaching and gentle process to remove pectin and lignin in the hemp fiber without destroying the strength of the fiber. The process condition is 110°C×45min, and the amount of caustic soda is 1.5g / L; The dyeing is carried out on th...

Abstract

The invention discloses a production process of cotton-hemp blended yarn-dyed woven fabric. The production process mainly includes the steps of a, producing warps and wefts; b, dyeing; c, sizing; d, weaving fabric; e, finishing the fabric. The production process has the advantages that hemp fiber is treated reasonably so that spinnability and spinning quality of the hemp fiber are improved; the warps and wefts are produced by the unique production method according to a unique raw material ratio, so that the blended fabric produced has excellent properties such as softness in touch, breathability, high wearing comfort, mildew resistance and microbial proofing.

Description

technical field [0001] The invention relates to the technical field of fabric fabrics, in particular to a preparation process of cotton / hemp blended yarn-dyed woven fabrics. Background technique [0002] Hemp is a kind of green functional fiber, which has the characteristics of moisture absorption, breathability, cool feel, antistatic, anti-mildew and antibacterial, etc. With its excellent performance, many functional textiles can be developed. [0003] Under the current international economic background, it is difficult for textiles with a single raw material to stand out, so increasing the development of blended products is an inevitable trend. Blending hemp fiber with other natural fibers, synthetic fibers and new fibers, such as blending hemp with cotton, wool, tencel, modal, bamboo pulp fiber, microporous polyester fiber, etc., can achieve complementary advantages and develop unique High value-added clothing textiles. [0004] However, the hemp fiber has high rigidity...
