Embodiment 1

[0034] Heat 100g of nylon-cotton blended fabric at 90°C for 10 minutes for pretreatment, then add 1000g of water, 3g of C.I. reactive red 8, and 0.4g of potassium octadecanoate soap after cooling, control the temperature at 25°C, and keep it warm for 10 minutes , then add sodium sulfate and keep warm for 10 minutes, then heat up to 80°C at a rate of 1°C / min, then keep warm at 80°C for 30 minutes, add 20g of soda ash, and keep warm for 30 minutes; after the heat preservation is completed, drain the residual liquid , wash with cold water at 0-5°C for 10 minutes, heat up to 98°C for soaping for 10 minutes, drain the residue, wash with cold water at 0-5°C, adjust the pH to 5.0 with glacial acetic acid, and then rinse with cold water at 0-5°C Wash for 10 minutes and dry to obtain the dyed finished product. The brocade staining reaches grade 5. The test method adopts the national standard GB251-2008-T gray sample card for staining.

Embodiment 2

[0036] Heat 100g of nylon-cotton blended fabric at 90°C for 10 minutes for pretreatment, then add 1000g of water, 3g of C.I. active red 8, and 0.4g of pull-off powder BX after cooling, control the temperature at 25°C, and keep it warm for 10 minutes. After adding sodium sulfite and keeping it warm for 10 minutes, heat it up to 80°C at a rate of 1°C / min, then keep it warm at 80°C for 30 minutes, add 20g of soda ash, and keep it warm for 30 minutes; after the heat preservation is completed, drain the residual liquid, Wash with cold water at 0-5°C for 10 minutes, heat up to 98°C for soaping for 10 minutes, drain the residue, wash with cold water at 0-5°C, adjust the pH to 5.0 with glacial acetic acid, and wash with cold water at 0-5°C After drying for 10 minutes, the dyed finished product is obtained, and its brocade reaches 4 grades.

Embodiment 3

[0038] Heat 100g of nylon-cotton blended fabric at 90°C for 10 minutes for pretreatment, then add 1000g of water, 3g of C.I. active yellow 3, and 0.4g of sodium tetradecenyl sulfonate after cooling, keep warm for 10 minutes, and then add elemental After keeping the powder warm for 10 minutes, raise the temperature to 80°C at a rate of 1°C / min, then keep it at 80°C for 30 minutes, add 20g of soda ash, and keep it warm for 30 minutes; Wash in cold water at 5°C for 10 minutes, heat up to 98°C for soaping for 10 minutes, drain the residue, wash with cold water at 0-5°C, adjust the pH to 5.0 with glacial acetic acid, and wash with cold water at 0-5°C for 10 minutes. Dried to obtain dyed finished products, the brocade reached 5 grades.

Abstract

The invention discloses an anti-staining dyeing process for a nylon-cotton blended fabric. The process comprises: adding a nylon-cotton blended fabric, a dye and an auxiliary agent to water, controlling a temperature at 20-30 DEG C, adding anhydrous sodium sulfate under a stirring condition, uniformly heating to achieve a temperature of 80-90 DEG C, carrying out thermal insulation for 0.5-1 h, adding an alkali to adjust the pH value to 9-11, continuously carrying out thermal insulation for 0.5-1 h, cooling to achieve a room temperature, removing the residue liquid, sequentially carrying out water washing, soaping and water washing, adopting glacial acetic acid to adjust the pH value to 5.0, and carrying out water washing and drying to obtain the dyed finished product, wherein the auxiliary agent is an anionic surfactant. According to the present invention, the used auxiliary agent anionic surfactant can be combined with NH<3+> on the nylon fibers in a salt type bond form, such that the reaction between the amino group on the nylon fibers and the active group of the active dye can be reduced, the combination of the nylon and the dye during the cotton dyeing process can be prevented, and the nylon staining grade is improved.

Description

technical field [0001] The invention belongs to the field of dye compositions, and in particular relates to an anti-staining dyeing process for nylon-cotton blended fabrics. Background technique [0002] Cotton nylon fabric is currently a popular clothing fabric. Among them, cotton fiber feels soft, has good air permeability and moisture absorption, and is comfortable to wear, but it is easy to wrinkle; nylon fiber has high resilience and fatigue resistance, and has good moisture absorption performance. After interweaving cotton and nylon, the fabric can not only have the advantages of nylon and cotton fibers, but also overcome their respective shortcomings, showing a strong body and smooth feel. When dyeing cotton nylon fabric, due to the difference in chemical structure of nylon fiber and cotton fiber, its dyeing process has particularity. [0003] Reactive dyes are one of the main dyes for cotton fiber dyeing. Since the appearance of commercial products in 1956, the vari...
