Production method of all-wool yarn knitted fabric

Abstract

The invention relates to a production method of all-wool yarn knitted fabric. The method comprises the steps of: preparing wool tops into fabric sequentially by dyeing and re-combing, spinning, weaving, and after treating processes; the dyeing step in the dyeing and re-combing processes comprises the steps of: filling the wool tops into a dye vat, adding water, heating and maintaining the temperature at 35-40 DEG C, adding acetic acid to adjust pH value of dye bath to 4-5, then adding a low temperature fast dyeing assistant and a lanasol dye, and operating for 5-15min; then heating at a speed of 2.0 DEG C / min to 3.0 DEG C / min to 80-90 DEG C, and maintaining the temperature for 30-50min; a compact spun yarn spinning device is adopted in a spun yarn step in the spinning process; a circular knitting machine is adopted in the weaving process; and the after treating process comprises a heat setting step and a flat washing and flat cooking step. The fabric prepared by the production method of all-wool yarn knitted fabric provided by the invention is good in rebound resilience, stable in size and level in fabric face, and the fluffing and pilling phenomena are completely improved.

Description

technical field [0001] The invention relates to a fabric weaving method, belonging to the technical field of wool weaving. Background technique [0002] With the continuous improvement of living standards, all-wool knitted fabrics have attracted more and more attention as a high-grade fabric. All-wool knitted fabric is a fabric formed by bending all-wool yarns into loops with knitting needles and interlacing them with each other. There are extremely strict requirements for the entire weaving process of the fabric, from spinning to weaving to finishing. Guarantee the high quality and high quality of the fabric. However, the full wool knitted fabrics on the market are often due to the unsuitable weaving method, which greatly reduces the quality of the fabrics. The common problem is the use of mordant dyeing process. Although the color is uniform, the color fastness is good, and the cost is low, the dyeing temperature is high, the time is long, the damage to the wool is great...

AI Technical Summary

Problems solved by technology

This dyeing method is low temperature and fast, but the dyeing with mordant dyes needs to add mordant dyes and mordant dyes in multiple steps. The steps are relatively cumbersome, and the high temperature and heat preservation time is long, which is still not conducive to the protection of wool.
