Embodiment Construction

[0016] Sequential steps:

[0017] 1) Yarn loose warping;

[0018] 2) The yarn is pre-treated in the dyeing vat;

[0019] 3) Dyeing and forming a loose dyeing axis;

[0020] 4) Roll up and stack for 16-18 hours at an ambient temperature of 20-30°C;

[0021] 5) Soaping and dehydration in the dye vat;

[0022] 6) Sizing the warp beam on the sizing machine to form a weaving beam.

[0023] in:

[0024] 1. The amount of dyeing solution:

[0025] Reactive dye Xg / l

[0026] Reactive leveling and dispersing agent 1-3ml / l

Abstract

The invention provides a loose type yarn beam salt-free cold-stacking dyeing processing technique, which relates to the technical field of textiles, in particular to a technique and a method for yarn dyeing. The technique comprises the following sequential steps: warping yarn in a loose type, carrying out preliminary treatment on the yarn in an dye vat, dyeing, and forming a loose type dyeing beam, coiling and stacking for 16-18 hours under a condition of the environmental temperature of 20-30 DEG C, soaping and dewatering in the dye vat, sizing by a yarn beam on a sizing machine and forming a loom beam. The invention changes the traditional production mode and procedure of colored woven cloth, does not use salt during dyeing and is beneficial to the subsequent sewage treatment, and the coloration rate of dye is as high as 90%. In the invention, yarn is coiled into a beam for stacking during dyeing, subjected to dyeing at normal temperature and does not need steam; the invention also saves electricity and has obvious advantages in the aspects of energy saving and consumption reduction.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a yarn dyeing process and method. Background technique [0002] At present, the dip-dyeing process commonly used in yarn dyeing is divided into three types: skein dyeing, package dyeing and warp beam dyeing. These three methods all have the defects of high energy consumption and high pressure of sewage treatment. In addition, the color yield of the existing exhaust dyeing process is only 70%, which is not conducive to saving dyestuffs. [0003] With the development of technology, dyes suitable for cold-batch dyeing have come out one after another, and have been maturely applied in the pad dyeing industry. Contents of the invention [0004] The purpose of the invention is to reduce the high energy consumption of yarn dyeing and the difficulty of sewage treatment in a yarn loose warp beam salt-free cold-batch dyeing process. [0005] The present invention comprises the followi...
