Problems solved by technology

[0002] Most of the existing dyeing and finishing methods for rayon fabrics use reactive dyes for direct printing, and the small floral pattern is acceptable in the market, but when it comes to patterns with dark background and light-colored small flowers, the printing effect is blurry and rough, and the three-dimensional effect is poor. Market reaction is not ideal

Embodiment Construction

[0014] The present invention is described in detail below: the present invention has the following steps:

[0015] 1): Pretreatment of semi-finished rayon products: singeing semi-finished rayon products on a singeing machine, the singeing method is one positive and one reverse, the speed of the singeing machine is 100m / min; the enzyme is rolled in the singeing machine trough ( Chuanhua CL-88G), adding a refining agent with a concentration of 4g / l (Demei DM-1239), a desizing agent with a concentration of 2g / l, controlling the liquid squeeze rate to 70%, and stacking in the drop car for 2 hours Then the stacked rayon semi-finished product is further processed by the air intake machine and added with a desizing agent, a penetrating agent and a refining agent with a concentration of 4g / l. The water temperature is controlled at 90°C for 30 minutes, and finally the temperature is lowered and washed with water. Used; the purpose is to clean the pulp impurities contained in the semi-f...

Abstract

The dyeing and finishing method of discharge print of the spun rayon fabric comprises the following steps that (1) singeing of spun rayon semi-finished products is carried out on a singeing frame, the spun rayon semi-finished products are stacked on a doffing trolley, and the stacked spun rayon semi-finished products enter an air flow machine to be further processed, and are cooled and washed with water to be used; (2) the spun rayon semi-finished products washed with the water are guided into an overflowing machine, are guided out in a cold wash mode, and enter a rope form washing machine to be processed in a soaping mode; (3) the wet spun rayon semi-finished products processed in the soaping mode are fed into a setting machine and are wound to form rolls; (4) discharge print is carried out on the set spun rayon semi-finished products with indanthrene dye, reduction washing is carried out on the spun rayon semi-finished products on the rope form washing machine, and the spun rayon semi-finished products are dried; (5) dried print fabrics are fed into the setting machine, softness arrangement is carried out on the dried print fabrics, and the width, needed by a client, of the print fabrics is well controlled. The dyeing and finishing method of discharge print of the spun rayon fabric has the advantages that the printing effect of the discharge print technology is ensured, and the number of defectives is reduced as much as possible; the spun rayon fabric has better hand feeling, perfect products are produced, and the demand of the client is met.

Description

technical field [0001] The invention relates to a fabric dyeing and finishing method, in particular to a dyeing and finishing method of rayon fabric discharge printing. Background technique [0002] Most of the existing dyeing and finishing methods for rayon fabrics use reactive dyes for direct printing, and the small floral pattern is acceptable in the market, but when it comes to patterns with dark background and light-colored small flowers, the printing effect is blurry and rough, and the three-dimensional effect is poor. The market reaction was far from ideal. Contents of the invention [0003] The purpose of the present invention is to change the above situation, choose Shihlin dyes to discharge reactive dyed cloth, and do the opposite, so as to provide a rayon that allows the pattern of dark-colored and light-colored flowers to obtain a strong three-dimensional effect Dyeing and finishing method of fabric discharge printing. [0004] The object of the present inven...
