Embodiment 1

[0009] Referring to Fig. 1, the flax long fibers are combed into slivers of about 18cm, and the slivers are passed through multiple drawing frames: in the first drawing, the second drawing, the third drawing, the fourth In the drawing frame, the flax fiber is continuously drawn and merged, and the bamboo fiber is mixed in the fifth drawing frame. The bamboo fiber is uniform in length, accounting for 8% of the blended yarn mass, and the bamboo fiber and the flax are drawn. Stretched and combined into roving. The roving is scoured and bleached, and the scoured and bleached process includes two processes of sub-bleaching and oxygen bleaching, and the sodium chlorite NaCLO of 1.5g / L is added in water earlier. 2 , the pH value is 2.5, the initial temperature is 30°C, it takes 30 minutes to raise the temperature to 50°C, keep warm for 30 minutes, wash with water, then carry out oxygen bleaching, add 3.5g / L hydrogen peroxide H 2 o 2 , pH value 10, initial temperature: 50°C, take 30...

Embodiment 2

[0011] Referring to Fig. 1, the flax long fibers are combed into slivers of about 18cm, and the slivers are passed through multiple drawing frames: in the first drawing, the second drawing, the third drawing, the fourth In the drawing frame, the flax fiber is continuously drawn and merged, and the bamboo fiber is mixed in the fifth drawing frame. The bamboo fiber is uniform in length and accounts for 40% of the blended yarn mass. Stretched and combined into roving. The roving is scoured and bleached, and the scoured and bleached process includes two processes of sub-bleaching and oxygen bleaching, and the sodium chlorite NaCLO of 1.5g / L is added in water earlier. 2 , the pH value is 3, the initial temperature is 30°C, it takes 30 minutes to raise the temperature to 50°C, keep warm for 40 minutes, wash with water, then carry out oxygen bleaching, add 3.5g / L hydrogen peroxide H 2 o 2 , pH value 10, initial temperature: 50°C, take 30 minutes to raise the temperature to 95°C, ke...

Embodiment 3

[0013] Referring to Fig. 1, the flax long fibers are combed into slivers of about 18cm, and the slivers are passed through multiple drawing frames: in the first drawing, the second drawing, the third drawing, the fourth The flax fiber is continuously drawn and merged in the drawing frame of the first pass, and the bamboo fiber is mixed in the drawing process of the fifth pass. The length of the bamboo fiber is uniform, accounting for 75% of the blended yarn mass percentage. Stretched and combined into roving. The roving is scoured and bleached, and the scoured and bleached process includes two processes of sub-bleaching and oxygen bleaching, and the sodium chlorite NaCLO of 1.5g / L is added in water earlier. 2 , the pH value is 3.5, the initial temperature is 30°C, it takes 30 minutes to raise the temperature to 50°C, keep warm for 25 minutes, wash with water, then carry out oxygen bleaching, add 3.5g / L hydrogen peroxide H 2 o 2 , pH value 10.5, initial temperature: 50°C, tak...

Abstract

The invention discloses a method for producing flax blended yarn used in clothes and face fabric, comprising that: preparing flax long fiber into flax bars; combing bars via at least five processes; adding bamboo fibers into combining process, while the bamboo fibers are 8-75mass% of total blended yarn mass; combing them and drawing to prepare rove; boiling and bleaching the rove; spinning into spun yarn; drying, coiling and shaping. The invention has simple process, while the product has uniform bars, beautiful appearance and smooth surface.

Description

technical field [0001] The invention relates to a weaving method, in particular to a production process of flax blended yarn used for clothing and home textile fabrics. Background technique [0002] Flax is a rare natural species. Natural flax fiber has strong hygroscopicity, good heat dissipation and air permeability, anti-mildew and moth resistance, no static electricity, no chemical components, and unique characteristics of inhibiting bacterial growth and effectively blocking ultraviolet penetration. The world is known as the "Fiber Queen". However, pure flax spun yarn has rough appearance, uneven evenness, poor spinnability, monotonous color, no luster, hard hand and no smooth feeling. At the same time, there are certain technical difficulties in spinning high-count yarns from pure flax. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art and provide a production process of fl...
