Embodiment 1

[0017] Use enzymes, desizing agents, degreasing scouring agents and penetrating agents to cold pile gray fabrics, wash them with water washing machines, and use Fong's Monforts sizing machines for presetting treatment. After the above treatments, the fabrics are sprayed and pressure treated in machine cylinders. The water level is controlled at 3.5 tons, the bath ratio is 1:15, the speed of the fabric is adjusted by spraying pressure when the vat is running, and then 98% concentrated sulfuric acid, the dosage is 0.6g / L, added to the auxiliary vat to dilute and stir evenly. Then slowly add it into the above-mentioned machine vat, raise the temperature to 90°C, and keep it warm for 80 minutes to pickle, wash with water after pickling, neutralize with soda ash to neutrality, and then dye, and the fabric after opening can be obtained after setting.

Embodiment 2

[0019] Use enzymes, desizing agents, degreasing scouring agents and penetrating agents to cold pile gray fabrics, wash them with water washing machines, and use Fong's Monforts sizing machines for presetting treatment. After the above treatments, the fabrics are sprayed and pressure treated in machine cylinders. The water level is controlled at 4 tons, the bath ratio is 1:18, the speed of the fabric is adjusted by spraying pressure when the vat is running, and then 98% concentrated sulfuric acid is added to the auxiliary vat to dilute and stir evenly. Then slowly add it into the above-mentioned machine vat, raise the temperature to 105°C, and keep it warm for 100 minutes to pickle, wash with water after pickling, neutralize with soda ash to neutral, then dye, and set the shape to get the fabric after opening.

Embodiment 3

[0021] Use enzymes, desizing agents, degreasing scouring agents and penetrating agents to cold pile gray fabrics, wash them with water washing machines, and use Fong's Monforts sizing machines for presetting treatment. After the above treatments, the fabrics are sprayed and pressure treated in machine cylinders. Choose the water level to be controlled at 4.5 tons, and the bath ratio to be 1:20. The speed of the fabric is adjusted by spraying pressure when the vat is running, and then add 98% concentrated sulfuric acid at a dosage of 1.2g / L to the auxiliary vat to dilute and stir evenly. Then slowly add it into the above-mentioned machine vat, raise the temperature to 120°C, and keep it warm for 120 minutes for pickling, after pickling, wash with water, neutralize with soda ash to neutral, then dye, and set the shape to get the fabric after opening.

Abstract

The invention relates to a modal woven fabric splitting process which comprises the following steps: performing cold-batch treatment on a cloth blank by using enzyme, a desizing agent, a scouring agent and a penetrant, washing in water and preforming, performing spraying and pressing treatment on the treated cloth blank in a cylinder, controlling the water level to be within 3.5-4.5 tons and the bath ratio to be 1:(15-20), adding sulfuric acid into a secondary cylinder, diluting and uniformly stirring, subsequently slowly adding into the cylinder, heating up, keeping the temperature and pickling, further washing the pickled cloth blank in water, neutralizing by using sodium carbonate so as to obtain a split fabric. The split fabric prepared by using the process overcomes the defects of the prior art, impurity fibers on the surface of the cloth can be completely eliminated, moreover the fabric is soft in hand feeling and high in velvet feeling, the process is simple and feasible, and fur removing and splitting can be performed simultaneously.

Description

technical field [0001] The invention belongs to the field of dyeing and finishing engineering in the textile industry, and in particular relates to a fiber opening process for modal woven fabrics. Background technique [0002] Modal is a cellulose regenerated fiber of viscose fiber with high wet modulus. The raw material of this fiber is beech wood, which is first made into wood pulp, and then processed into fiber through a special spinning process. The raw materials of this product are all natural materials. It is harmless to the human body, can be decomposed naturally, and is harmless to the environment. In addition, it also has the advantages of air permeability and water absorption, so it has a wide range of applications in today's society. Woven fabrics are composed of yarns interlaced in the warp and weft directions. They have the advantages of stable structure, smooth cloth surface, and generally no drooping phenomenon when hanging, and are in a leading position in th...
