Embodiment 1

[0009] It is processed by a multi-functional dyeing machine with a small liquor ratio. The multi-functional dyeing machine consists of a frame, a padding car, a No. 1 cloth guide roller, a No. 2 cloth guide roller and a dye vat; There is also a No. 1 cloth guide roller on the frame on the opposite side of the car, and a dye vat is located directly below the frame. There is No. 2 cloth guide roller; acid fiber opening solution is added into the liquid setting tank, and the fiber opening solution contains 5 g / L of sulfuric acid.

Embodiment 2

[0011] It is processed by a multi-functional dyeing machine with a small liquor ratio. The multi-functional dyeing machine consists of a frame, a padding car, a No. 1 cloth guide roller, a No. 2 cloth guide roller and a dye vat; There is also a No. 1 cloth guide roller on the frame on the opposite side of the car, and a dye vat is located directly below the frame. There is No. 2 cloth guide roller; acid fiber opening solution is added into the liquid setting tank, and the fiber opening solution contains 8 g / L of sulfuric acid, and the fabric is treated at 80°C for 60 minutes by a multi-functional dyeing machine, and the bath ratio is 1:3.

Embodiment 3

[0013] It is processed by a multi-functional dyeing machine with a small liquor ratio.

Abstract

The invention relates to the technical field of fabric dyeing and finishing, in particular to a splitting process for modal and cuprammonium rayon. The process comprises the following specific steps:a multifunctional dyeing machine with small bath ratio is adopted for processing and comprises a rack, a padder, a cloth guide roller I, a cloth guide roller II and a dye vat, wherein the padder is arranged at one end of the rack, the cloth guide roller I is arranged on the side, opposite to the padder, of the rack, the dye vat is arranged under the rack, a downwards concave liquid storage grooveis formed in the bottom of the dye vat, and the cloth guide roller II is arranged in the liquid storage groove; an acidic splitting solution is added to the liquid storage groove and contains sulfuricacid with concentration of 5-10 g / L, fabric is processed by the multifunctional dyeing machine at 80 DEG C for 60 min, and the bath ratio is 1:3. The multifunctional dyeing machine with small bath ratio is adopted for splitting processing and is low in rotation speed and tension, the fabric is in a loose state, and iron-shine marks and crease marks cannot be produced.

Description

technical field [0001] The invention relates to the technical field of fabric dyeing and finishing, in particular to a fiber-opening process for fabrics. Background technique [0002] The principle of modal and cupro fiber opening: Under acidic conditions, cellulose is hydrolyzed, which makes the fabric fluffy and distressed. The stronger the acidity, the higher the temperature, the greater the hydrolysis, which will cause the fabric to lose its strength and lose its wearability. . The existing fiber-opening process of modal and cupro filaments is carried out in a high-temperature and high-pressure jet overflow tank, and the process conditions are: adding sulfuric acid 1-2 g / L, bath ratio 1:10, and treating at 110 ° C for 30 minutes. The disadvantage of this process is that the cylinder is easily damaged, and at the same time, the cloth is easily brittle, and it is easy to produce aurora marks and wrinkle marks. SUMMARY OF THE INVENTION [0003] The purpose of the presen...
