Problems solved by technology

[0002] The existing overflow cylinder dyeing production process cannot meet the production requirements of low-denier multi-strand fiber fabrics, and problems such as snagging, doubling, and color flowering generally occur, and the hand feeling of the fabric is hard, and the anti-pilling level is low. The problem has a lot to do with spinning equipment, surface accuracy of dyeing vats, dyes, auxiliaries and process control conditions

Embodiment 1

[0024] An anti-snag and anti-pilling fiber fabric dyeing process comprises the following steps:

[0025] A. Cylinder distribution: When the gray cloth of 20D / 48F polyester high elastic yarn is put into the warehouse, the cloth rack should be wrapped with plastic paper or cloth, and the operator should wear white knitted gloves when moving the cloth. The cloth needs to be wrapped with a special cloth cover, and a certain amount of gray cloth is matched for each dyeing vat to ensure that the phenomenon of snagging is reduced;

[0026] B, chemical dyes: use sandpaper to polish the non-smooth surface of the dyeing vat to prevent snagging, add 40 ℃ warm water to the chemical material vat, add dyes according to the concentration requirement of 2.5g / L, stir for 30 minutes, and use a filter Net filter to ensure that all dyes have been dissolved;

[0027] C. Adding dyes: At room temperature, add water and 2g / L of emulsified degreasing agent produced by Wuxi Debang to the dye vat, then...

Embodiment 2

[0035] An anti-snag and anti-pilling fiber fabric dyeing process comprises the following steps:

[0036] A. Cylinder distribution: When the gray cloth of 30D / 96F polyester high elastic yarn is put into the warehouse, the cloth rack should be wrapped with plastic paper or cloth, and the operator should wear white knitted gloves when moving the cloth. The cloth needs to be wrapped with a special cloth cover, and a certain amount of gray cloth is matched for each dyeing vat to ensure that the phenomenon of snagging is reduced;

[0037] B. Chemical dyes: use sandpaper to smooth the rough surface of the dyeing vat to prevent snagging, add 50 ℃ warm water to the chemical material vat, add dyes according to the concentration requirement of 4g / L, stir for 40 minutes, and use a filter screen Filter to ensure that all dye has dissolved;

[0038] C. Adding dyes: At room temperature, add water and 4g / L of emulsified degreasing agent produced by Wuxi Debang to the dye vat, then add 4g / L o...

Abstract

The invention discloses a snagging-prevention and anti-pilling fiber fabric dyeing technology. The technology comprises the following steps of vat distributing, dye melting, dye adding, warming, heat preservation, cooling, color fixing, acid pickling and finished-product shaping. The shaping temperature is controlled to be 130-170 DEG C, and the shaping padder speed is controlled to be 25-28 m per minute. Meanwhile, a four-in-one softening agent of 1-5 g/L is added, plain cloth passes through a padder, and thus the hand feeling of fabric is made soft. In this way, 20D or 30D dacron high-stretch-yarn fabric obtained through the snagging-prevention and anti-pilling fiber fabric dyeing technology is soft and comfortable, the hand feeling is similar to that of cotton, and the phenomena of snagging and defect dyeing of fabric of 48 F or above are effectively reduced; besides, the anti-pilling grade is high, and the dyeing quality of the fabric is good.

Description

technical field [0001] The invention relates to the field of fabric dyeing, in particular to an anti-snag and anti-pilling fiber fabric dyeing process. Background technique [0002] The existing overflow cylinder dyeing production process cannot meet the production requirements of low-denier multi-strand fiber fabrics, and problems such as snagging, doubling, and color flowering generally occur, and the hand feeling of the fabric is hard, and the anti-pilling level is low. The problem has a lot to do with spinning equipment, surface accuracy of dyeing vats, dyes, auxiliaries and process control conditions. [0003] During the dyeing process of low-denier fabrics, since the single-fiber fineness of yarn above 48F is below 05 denier, the fibers shrink and fluff, so under the action of external force, the fibers are easy to break or float on the surface of the yarn, resulting in snagging and fluffing Problems such as low balls need to be improved on the dyeing process.
