AI Technical Summary

Problems solved by technology

The filaments obtained by this process are uniform and fully drawn non-elastic filaments, and special effects cannot be obtained, such as slub filaments
In addition, due to the high spinning speed and high draw ratio of the existing FDY process, there are relatively many wool and broken ends

Abstract

The invention relates to a dyeing process for chinlon bamboo joint fabric cotton fibre. The dyeing process comprises the steps of carrying out earlier stage processing, refining, dyeing, drying and aftertreatment on cotton fibre, wherein during dyeing step, reactive dyes are adopted, specifically, the process comprises the following steps: putting the dyes and anhydrous sodium sulphate into a dye vat for mixing for 20-30 minutes according to different color requirements and ratio of various dyes, running for 10-30 minutes under normal temperature, rising the temperature till reaching the temperature needed by dyeing at the speed of 0.5-3 DEG C / minute, selecting a proper alkali adding ratio curve according to different characteristic of dyes, adding alkali liquids by adopting automatic alkali adding equipment, keeping the temperature for 15-30 DEG C, discharging residual liquid and carrying out aftertreatment. A fabric manufactured by the cotton fibre has advantages of good abrasive resistance, washability, good colour fastness and the like.

Description

technical field [0001] The invention relates to a dyeing process, in particular to a dyeing process of cotton fibers of nylon slub cloth with slub effects. Background technique [0002] Functional textile varieties are constantly coming out, such as sofa releases, curtain fabrics, decorative fabrics and other home textile fabrics. The filaments used in such fabrics require good dyeability, bright color, good luster, good drape, and individual style. [0003] Polyester FDY spinning process uses semi-dull or glossy polyester slices as raw materials, and the filaments are sprayed out through a circular hole spinneret, and then stretched uniformly by the differential speed of the drafting roller and the setting roller. The temperature of the drafting roller is usually 90- 95°C, roll speed 1800-2300 m / min, forming roll temperature is usually 130-145°C, roll speed 4500-4900 m / min, and then through the main network to increase the cohesion of the wire, winding and forming. In orde...
