Problems solved by technology

[0003] The existing polishing and dyeing process mainly includes boiling and bleaching→polishing→hot washing→washing→dyeing with five water steps. The process is complicated and the water consumption is huge, which does not meet the requirements of energy saving and cost reduction of modern technology.

Embodiment 1

[0024] Boiling and bleaching: first heat the first bath to 60°C, then add penetrant, then put the cotton fabric gray cloth into the first bath, and then add a cooking and bleaching aid: alkali in the first bath and H 2 o 2 , and then heat the first bath solution with added bleaching aid to 80°C and keep it warm for 40 minutes; drain into water: drain the first bath solution after bleaching and put it into the second bath solution; polishing and dyeing: put the first bath solution Keep the second bath liquid at 52°C, adjust the pH range of the second bath liquid between 6 and 8; then add the same bath enzyme hair remover to the second bath liquid; then add dye, and mix for 18 minutes, Run the machine for 5 minutes; then add Yuanming powder, mix the material for 22 minutes, and run the machine for 6 minutes; then add alkali, adjust the pH value range of the second bath to 11±0.5; finally heat the second bath to 60°C and keep warm for 20-30 minutes.

Embodiment 2

[0026] Boiling and bleaching: first heat the first bath to 60°C, then add penetrant, then put the cotton fabric gray cloth into the first bath, and then add a cooking and bleaching aid: alkali in the first bath and H 2 o 2 , and then heat the first bath solution with added bleaching aid to 80°C and keep it warm for 40 minutes; drain into water: drain the first bath solution after bleaching and put it into the second bath solution; polishing and dyeing: put the first bath solution Keep the second bath at 55°C, adjust the pH range of the second bath to be between 6 and 8; then add the same bath enzyme hair remover to the second bath; then add dye, and mix for 20 minutes, Run the machine for 6 minutes; then add Yuanming powder, and change the material for 25 minutes, and run the machine for 6 minutes; then add alkali, adjust the pH range of the second bath to 11±0.5; finally heat the second bath to 60°C and keep warm for 20-30 minutes.

Embodiment 3

[0028] Blanching and bleaching: first heat the first bath to 60°C, then add penetrating agent, then put the gray fabric of cotton-polyester blended fabric into the first bath, and then add scouring and bleaching aids in the first bath: base and H 2 o 2 , and then heat the first bath solution with added bleaching aid to 80°C and keep it warm for 40 minutes; drain into water: drain the first bath solution after bleaching and put it into the second bath solution; polishing and dyeing: put the first bath solution Keep the second bath liquid at 58°C, adjust the pH range of the second bath liquid between 6 and 8; then add the same bath enzyme hair remover to the second bath liquid; then add dye, and mix for 22 minutes, Run the machine for 8 minutes; then add Yuanming powder, mix the material for 28 minutes, and run the machine for 8 minutes; then add alkali, adjust the pH value range of the second bath to 11±0.5; finally heat the second bath to 60°C and keep warm for 20-30 minutes...

Abstract

The invention discloses a polishing and dyeing one-bath process for a fabric. The method comprises the following specific steps of: 1, boiling and bleaching: boiling and bleaching grey cloth; 2, discharging water and introducing water: discharging primary boiled and bleached bath foam, and introducing secondary bath foam; and 3, polishing and dyeing: keeping the temperature of the secondary bath foam at 52-58 DEG C, and adjusting the PH value of the secondary bath foam to 6-8; adding a one-bath enzyme fur eliminating agent into the secondary bath foam; adding a dye stuff, dissolving for 18-22minutes, and running for 5-8 minutes; adding anhydrous sodium sulphate, dissolving for 22-28 minutes, and running for 5-8 minutes; adding alkali, and adjusting the PH value of the secondary bath foam to 11+ / -0.5; and heating the secondary bath foam to 60 DEG C, and preserving heat for 20-30 minutes. Due to the adoption of the polishing and dyeing one-bath process, polishing and dyeing one-bath can be realized, the entire process can be finished by only adding water twice, and energy and cost are saved.

Description

technical field [0001] The invention relates to the field of fabric treatment, in particular to a one-bath method for fabric polishing and dyeing. Background technique [0002] Before the fabric is dyed, it is usually polished to improve the surface quality of the fabric, so that the surface finish of the fabric is improved, thereby increasing the quality grade of the fabric. The existing polishing and dyeing process is mainly to add glacial acetic acid to adjust the pH value of the bath solution to between 4 and 5 after boiling and bleaching, and then add a depilatory agent to polish the fabric. In the dyeing process, for example, cotton fiber dyeing requires The pH value is between 6 and 8, so the polishing and dyeing process cannot be completed in one water, and two waters are required. At the same time, after the fabric is polished, the fiber hair ends will fall off in strips. In order to avoid the strip hair ends sticking to the surface of the fabric, it is necessary t...
