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. Select the water level to be controlled at 4 tons, and the bath ratio to be 1:18. 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 0.9g / L to the auxiliary vat to dilute and stir evenly. Then slowly add it into the above machine vat, raise the temperature to 105°C, and keep it warm for 100 minutes for pickling, after pickling, wash with water, and neutralize with soda ash until 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 to pickle. After pickling, wash with water, neutralize with soda ash to neutral, and then dye, and the fabric after opening can be obtained after setting.

Abstract

The invention relates to a process for opening fibers of modal woven fabrics, which comprises the following process steps: using enzymes, desizing agents, scouring agents and penetrating agents to cold pile gray fabrics, washing with water and presetting; Pressure spraying treatment is carried out in the tank, the water level is selected to be controlled between 3.5~4.5 tons, and the bath ratio is 1:15~20; add sulfuric acid to the auxiliary tank to dilute and stir evenly, then slowly add it to the above-mentioned machine tank, heat up, and keep warm for pickling; the pickled fabric is then washed with water and neutralized with soda ash to obtain the fabric after opening. The opening fabric prepared by this process overcomes the shortcomings of the prior art and can make the cloth surface The impurity wool on the hairiness is removed cleanly, and the fabric feels soft and has a strong velvet feel. This process is simple and easy, and realizes the simultaneous progress of hair removal and fiber opening.

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...
