Embodiment Construction

[0015] A kind of preparation method of bleached hemp polyester wool yarn, it comprises the following steps:

[0016] Step 1: Pre-wet the natural cannabis for 10-14 hours;

[0017] Step 2: Bleaching natural cannabis;

[0018] Step 3: Mix wool, polyester and bleached hemp at a ratio of 0.5:0.35:0.15 to produce evenly mixed mixed strips;

[0019] Step 4: Merge, draft and comb the mixed sliver 3-5 times by using the needle board, combing machine and circular comb to obtain a dry yarn; The total input amount is adjusted from the conventional 200g to 175g. The slivers are arranged in a double-row cross arrangement, and the ratio of crude oil and crude oil is optimized. The yarn count is adjusted to about 46, and the twist coefficient is between 105T / M-110T / M.

[0020] Step 5: In the process of dry-spinning the yarn, reverse-twist yarn technology is used to obtain worsted yarn.

[0021] Pre-wetting is carried out before each step, and the cohesion force of the hemp fiber is poor, ...

Abstract

The invention relates to a preparation method of blanched hemp, polyester and wool yarn. The preparation method comprises steps as follows: S1: natural hemp is pre-wetted for 10-14 h; S2: the naturalhemp is blanched; S3: wool, polyester and the blanched hemp are mixed in the ratio of 0.5:0.35:0.15, and uniformly mixed silvers are produced; S4: the mixed silvers are mixed, drafted and carded 3-5 times through a needle board, a combing machine and a circular combing machine, and yarn strands are obtained; S5: a countertwisting technology is adopted in the spinning process of the yarn strands, and spun yarn is obtained. Pre-wetting is performed separately before each step, superfine wool is selected as the wool, and dumbbell-shaped low-temperature cation tingible polyester fiber is selectedas the polyester. The method has the advantages as follows: the yarn keeps the warm-keeping and comfortable advantages of the wool and also has the moisture absorption and sweat releasing property ofthe polyester and the environment-friendly antibacterial property of the hemp, advantages of different fibers are played, the functionability of a product is improved, and different demands of the yarn market are met.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a method for preparing bleached hemp polyester wool yarn. Background technique [0002] Wool-polyester blending is one of the more common blended yarns at present. It can maintain the advantages of wool and give full play to the advantages of polyester. The blending ratio can be adjusted according to the needs of the fabric. Under wet conditions, the elasticity and wear resistance are good. However, under the pressure of shortage of raw materials and environmental pollution, people began to turn their attention to green resources that have no environmental pollution and can be recycled. Hemp fiber is a high-quality cellulose The fiber has ecological characteristics such as moisture absorption, breathability, UV protection, antistatic and antibacterial health functions, and has won the favor of consumers. [0003] In this research and development, a certain proportion of wool, hemp and po...
