Embodiment 1

[0012] Pre-treatment of viscose fiber fabrics, using continuous pad dyeing equipment, including singeing, desizing, tentering and pre-shrinking processes:

[0013] Singeing: Singeing is performed on viscose fabrics, and strong singeing is not allowed.

[0014] Desizing: add caustic soda 9g per liter of water, chelating dispersant cm-5 2g, wax remover WR 4g, refining agent 88ECO 4g.

[0015] The desizing machine must have a damp cloth, that is, the fabric comes out of the desizing machine with a moisture content of more than 50%. And adjust the pressure of each rolling car of the desizing machine at 0.1-0.2MPa.

[0016] Bleaching: Add 2.5 g of 100% hydrogen peroxide, 7 g of stabilizer, and 8 g of soda ash per liter of water. Soda ash acts as a softener on the inside, adjusting the pH to 10-10.5.

[0017] The stenter is soft and pre-shrunk, and the stenter frame is not allowed to wear a rolling car.

Embodiment 2

[0019] In the desizing process, add 10g of caustic soda, 1.5g of chelating dispersant cm-5, 5g of wax remover WR, and 3g of refining agent 88ECO per liter of water.

[0020] In the bleaching process, add 3g of 100% hydrogen peroxide, 8g of stabilizer and 7g of soda ash per liter of water.

[0021] All the other are with embodiment 1.

Embodiment 3

[0023] In the desizing process, add 8g of caustic soda, 2.5g of chelating dispersant cm-5, 3g of wax remover WR, and 5g of refining agent 88ECO per liter of water.

[0024] In the bleaching process, 2 g of 100% hydrogen peroxide, 6 g of stabilizer and 9 g of soda ash are added per liter of water.

[0025] All the other are with embodiment 1.

Abstract

The invention relates to a blended fabric dyeing and finishing technology, and particularly relates to a viscose fabric pretreatment method. The invention aims at providing a fabric dyeing and finishing technology to solve the problems of hard hand feeling in high temperature, efficient soaping, long technological processes and the like of the viscose fabric. The viscose fabric pretreatment method adopts continuous pad dyeing equipment and comprises the steps of singeing, desizing, tentering, preshrinking and the like, wherein caustic soda, chelating dispersing agent, dewaxing agent and refining agent are added in the desizing process; and 100% hydrogen peroxide, stabilizer and soda ash are added in the bleaching process. The method provided by the invention successfully solves the problems of hard hand feeling in high temperature, efficient soaping, long technological processes and the like of the viscose fabric. Through the method, the fabric dyeing process is more reasonable, the production is clean and environment-friendly, and the product quality is stable.

Description

Technical field [0001] The present invention involves a blended material printing and dyeing process, which is specifically a pre -treatment method of a glue fiber fabric. Background technique [0002] Nianjiao fiber (Viscose Fiber) has high strength and wet mold volume, moderate stretching and good curling properties, plus the adhesive fiber itself has excellent humidity, permeability, not static electricity, not static electricity, and not static electricity.The characteristics of good dyeing performance, fibrousness and length can be flexibly adjusted. It is a more comprehensive textile fiber raw material.The moisture absorption performance of sticky fiber is closely related to the dyeing performance and the fiber itself. It has a close relationship with a large amount of hydroxyl (—OH). The hydroxyl (—OH) group adsorb a large number of water molecules or other molecules.The sticky fiber has cracking fiber macromolecules due to the major physical and chemical reactions during ...
