Problems solved by technology

In addition, with the development of textile technology, the types of blended and interwoven fabrics of various cotton and chemical fibers have increased greatly, and the size components on the fabrics have become more and more complex. If they cannot be effectively removed, it will cause adverse effects on the subsequent dyeing and printing processes. influences
[0003] The current conventional cold pad batch process takes 24 hours, which takes a long time. The whiteness, capillary effect, and strength of the product are easily affected by other factors and are unstable, and a high-temperature hot-alkali treatment process of short-term steaming is still required to achieve The required pre-processing effect and high energy consumption
Moreover, the quality of semi-finished products processed by the cold pad batch process is not high, the size and impurities can not be removed completely, and the gross effect is low, which greatly affects the quality of the subsequent dyeing and finishing process. Lack of serialization, specialization, standardization and unified test standards, corresponding additives cannot meet the development requirements of cold pad batch process

Embodiment 1

[0032] The pretreatment process of textile fabrics specifically includes: singeing→rolling and cold-stacking working fluid (temperature 30°C)→stacking→hot water washing for 7-10 grids, temperature (98°C)→cold water washing→drying.

[0033] (1) Singeing: wind the dried fabric on the roll of the singeing machine, and use the gas singeing machine for singeing treatment; at the same time, turn the dust removal roller to perform dust removal treatment on the singeed fabric surface;

[0034] (2) Padding and cold-batch working liquid: the fabric after singeing is subjected to one dipping and one padding process; the dyeing tank is filled with padding liquid (temperature 30°C);

[0035] (3) Stacking: Roll the padded fabric on a coiling machine, and then stack it for 2 hours after wrapping;

[0036] (4) Then wash with hot water at 98°C for 7 compartments; then wash with cold water;

[0037] (5) Finally dry.

[0038] Among them, the liquid carrying rate of the padding liquid is ≥85%, ...

Embodiment 2

[0047] The pre-treatment process of textile fabrics specifically includes: singeing→rolling and cold-stacking working fluid→stacking→hot water washing for 8 grids, temperature (98°C)→cold water washing→drying.

[0048] (1) Singeing: wind the dried fabric on the roll of the singeing machine, and use the gas singeing machine for singeing treatment; at the same time, turn the dust removal roller to perform dust removal treatment on the singeed fabric surface;

[0049] (2) Padding and cold-batch working liquid: the fabric after singeing is subjected to one dipping and one padding process; the padding liquid is filled with a temperature of 30~40°C in the dyeing tank;

[0050] (3) Stacking: roll the padded fabric on a coiling machine, and then stack it for 4 hours after wrapping;

[0051] (4) Then wash in hot water at 98°C for 8 compartments; then wash in cold water;

[0052] (5) Finally dry.

[0053] Among them, the liquid carrying rate of the padding liquid is ≥85%, and its spec...

[0062] The pretreatment process of textile fabrics specifically includes: singeing→rolling and cold stacking working fluid→stacking→hot water washing for 10 grids, temperature (98°C)→cold water washing→drying.

[0063] (1) Singeing: wind the dried fabric on the roll of the singeing machine, and use the gas singeing machine for singeing treatment; at the same time, turn the dust removal roller to perform dust removal treatment on the singeed fabric surface;

[0064] (2) Padding and cold-batch working liquid: the fabric after singeing is subjected to a dipping and padding process; the dyeing tank is filled with padding liquid (temperature 40°C);

[0065] (3) Stacking: roll the padded fabric on a coiling machine, and then stack it for 6 hours after wrapping;

[0066] (4) Then wash in hot water at 98°C for 10 grids; then wash in cold water;

[0067] (5) Finally dry.

[0068] Among them, the liquid carrying rate of the padding liquid is ≥85%, and its specific components include:

Abstract

The invention belongs to the technical field of the dyeing pre-treatment of textile fabric, and particularly relates to a pre-treatment process for the textile fabric. The pre-treatment process for the textile fabric specifically comprises the following steps: singeing; rolling cold-batch working solution; piling; washing in 7-10 grids by hot water, wherein the temperature is 98 DEG C; washing bycold water; and drying. The pre-treatment process is capable of, through a DF-boiling and bleaching agent and other assistants, preparing the continuous, rapid, low-temperature, and low-alkaline efficient pre-treatment working solution, the working solution is extensively applied to a pre-treatment processing technology of textiles, such as pure cotton, polyester cotton, brocade cotton, rayon, non-woven fabric, dacron, and tencel, so the piling time can be reduced from 20-24 hours of a traditional cold-batch process to 2-6 hours, and the refining effect of cotton fabrics and the uniformity ofdyeing are greatly improved. The dye-uptake of the dyeing effect is improved by 10%-20%, and the hand feeling is softer.

Description

technical field [0001] The invention belongs to the technical field of dyeing pretreatment of textile fabrics, and in particular relates to a pretreatment process of textile fabrics. Background technique [0002] Fabric dyeing pretreatment is the basic process in the dyeing and finishing production process. It plays an important role in improving the product quality of the subsequent process. Its processing purpose is to remove natural impurities on the fabric and additional sizing and auxiliary agents in the textile process. and taint. Among them, cotton fabrics contain a large amount of cottonseed hulls, colloids, waxy substances, and a small amount of nitrogen-containing substances and other impurities; half of polyester-cotton and other chemical fiber fabrics contain synthetic pulp and additives such as PVA, CMC, and PA. In addition, with the development of textile technology, the types of blended and interwoven fabrics of various cotton and chemical fibers have increas...
