Embodiment 1

[0018] A cupro ammonia fiber cloth, wherein the cupro ammonia fiber single fiber fineness of the cupro ammonia fiber cloth should be below 2.2DTEX, the fabric structure design is reasonable, the tightness ratio: plain weave is less than or equal to 1.1, twill weave is less than or equal to 1.45, and its dyeing method includes the following step:

[0019] (1) Water washing process: roll the cupro ammonia fiber cloth into the dyeing jigger for cleaning, and add an appropriate amount of cleaning agent, and at a water temperature of about 60°C, wrap the cloth roll in the dyeing jigger in forward and reverse directions. The second time, the overflow water comes out of the cloth.

[0020] (2) Refining process: inject 2,500 liters of water into the dyeing machine, send the unrolled and washed cloth into the dyeing machine, soak and circulate it; % sodium hydroxide solution 200kg and degreasing spirit, so that the pH value of the solution is 13.5-14.5. After 10 minutes, start to heat...

Abstract

The present invention relates to a dyeing method of cuprammonium rayon fabric. Said method successively includes the water washing process, scouring process and dyeing process. The water washing process is used for debatching and primarily cleaning the grease and blob on the fabric surface, and the scouring process is used for removing size mixture and grease contained in the cuprammonium rayon fabric and blob on the fabric surface and can be used for raising permeability of coloring agent and uniformity of color absorption.

Description

technical field [0001] The invention mainly relates to a method for dyeing cloth, in particular to a method for dyeing cupro ammonia fiber cloth. Background technique [0002] In the modern textile industry, people have been trying to explore and develop an excellent regenerated natural plant fiber fabric to supplement and replace expensive and limited silk fabrics to meet market demand. At present, the most common method is to use viscose filaments and chemically synthesized polyester filament fabrics instead. However, due to the thick single fiber of viscose filament fibers, low wet strength, and high elongation, polyester fabrics have poor hygroscopicity and are prone to static electricity. Achieve the style and character of silk fabrics. Cupro fiber belongs to natural regenerated cellulose fiber, which is single and fine, has high hygroscopicity and wet strength, and does not generate static electricity, so it becomes an ideal substitute. Bu...
