High-count ring compact spun pure flax yarn and manufacturing process thereof

Abstract

The invention discloses a high-count ring compact spun pure flax yarn, consisting of 100 percent flax fiber. In the pure flax yarn, the yarn count is 42-60s, the uniform variance coefficient (CV) value of yarn evenness is 30-40 percent, the single yarn strength is 70-90N, the irregularity of the strength is 20-30 percent, the difference among spindles (CVb) is 2-4 percent, the number of slub endsper kilometer is 7500 to 8500, the number of neps per kilometer is 5000 to 6000, the number of fine end per kilometer is 4500 to 5000, and the twist is (100-150) / 10 centimeters. The invention also discloses a manufacturing process of the pure flax yarn, comprising the process flows of raw material selection, raw material pre-treatment, pure cotton opening, cotton carding, drawing, roving, spinning and automatic doffing. The pure flax yarn has the advantages of moisture absorption, heat dispersion, health protection, bacteria inhibition, dirty resistance, static electricity resistance, ultraviolet ray protection and excellent flame-retardant effect. A flax product has the characteristics of air permeability, smoothness, straightness and bacteria inhibition and killing, is difficult to produce static electricity to absorb dust and is not easily b corroded and damaged by worms and the like. Moreover, the manufacturing process is simple and ordered and can realize industrialized production due to the adoption of chemical treatment and mechanical processing.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a high-count pure linen yarn by ring-spinning compact spinning and a manufacturing process thereof. Background technique [0002] Flax fiber has many excellent properties. It absorbs moisture and dissipates heat, maintains health and inhibits bacteria, is anti-fouling, anti-static, anti-ultraviolet, and has excellent flame retardant effect. [0003] The outstanding feature of flax is that its fibers can absorb moisture equivalent to 1 / 5 of its own dry weight, and its surface does not feel wet. When it is heated, it can discharge volatilization faster than other fibers, and has better heat insulation function. Flax has far-infrared effect and anti-magnetic and anti-radiation properties. The medical dressing material made of flax not only has a certain anti-radiation ability and prevents the deposition of heavy metals, but also its outer layer can produce a special pr...

Problems solved by technology

Once the flax content exceeds 20%, there will be a sharp drop in production efficiency, and there will be many yarn defects, which will make weaving difficult, let alone the production of pure flax fiber products.
