Problems solved by technology

However, the scale layer of cashmere fiber contains lipid substances, and at the same time contains a large number of disulfide bond network crosslinks to form a dense structure, which hinders the diffusion of dye molecules and other reagent molecules to the internal structure of cashmere fibers, affecting the dyeing performance of fibers

Embodiment 1

[0029] A combination process of digital printing of cashmere fabric and traditional tie-dyeing, comprising the following steps:

[0030] 1) Establish a plan: decompose the original traditional tie-dye graphics stored in the computer, then recombine to complete the pattern design, decompose the completed pattern design again, and determine the tie-dyeing method, tie-dyeing color and printing pattern;

[0031] 2) Tie-dyeing: Put the tied cashmere fabric into the dyeing pot for dyeing. The dyeing process is: at room temperature, the dye and water are proportioned to form a dye solution, and the dye solution is heated at a heating rate of 2°C / min. Warm up to 36°C, add tied cashmere fabric, soak for 35min, add soda ash and sodium sulfate, the amounts of soda ash and sodium sulfate are respectively 0.6% and 0.8% of the quality of cashmere fabric; then heat up to 75°C, keep warm for 40min; finally lower the temperature to room temperature at a cooling rate of 3°C / min, and the dyeing ...

[0036] A combination process of digital printing of cashmere fabric and traditional tie-dyeing, comprising the following steps:

[0037] 1) Establish a plan: decompose the original traditional tie-dye graphics stored in the computer, then recombine to complete the pattern design, decompose the completed pattern design again, and determine the tie-dyeing method, tie-dyeing color and printing pattern;

[0038] 2) Tie-dyeing: Put the tied cashmere fabric into the dyeing pot for dyeing. The dyeing process is: at room temperature, the dye and water are proportioned to form a dye solution, and the dye solution is heated at a heating rate of 2°C / min. Heat up to 40°C, add tied cashmere fabric, soak for 30min, add soda ash and sodium sulfate, the amount of soda ash and sodium sulfate is respectively 0.5% and 1% of the quality of cashmere fabric; then heat up to 77°C, keep warm for 40 minutes; finally lower the temperature to room temperature at a cooling rate of 4°C / min, and the dyeing...

Embodiment 3

[0043]A combination process of digital printing of cashmere fabric and traditional tie-dyeing, comprising the following steps:

[0044] 1) Establish a plan: decompose the original traditional tie-dye graphics stored in the computer, then recombine to complete the pattern design, decompose the completed pattern design again, and determine the tie-dyeing method, tie-dyeing color and printing pattern;

[0045] 2) Tie-dyeing: Put the tied cashmere fabric into the dyeing pot for dyeing. The dyeing process is: at room temperature, the dye and water are proportioned to form a dye solution, and the dye solution is heated at a heating rate of 2°C / min. Warm up to 38°C, add tied cashmere fabric, soak for 32min, add soda ash and sodium sulfate, the amounts of soda ash and sodium sulfate are respectively 0.4% and 1.2% of the quality of cashmere fabric; then heat up to 75°C, keep warm for 40 minutes; finally lower the temperature to room temperature at a cooling rate of 5°C / min, and the dye...

Abstract

The invention discloses a digital printing and traditional dyeing combined process of a cashmere fabric. The process comprises the following steps: (1) establishing a scheme; (2) tie-dyeing; (3) performing the primary color fixation; (4) digitally printing; and (5) performing the secondary color fixation. The digital printing is effectively combined with the traditional dyeing, so that not only can the skin texture and the natural unvarnished style of the traditional manual dyeing be reasonably reserved, but also the patterns with rich shapes can be freely innovatively designed, the productionefficiency can be increased, the production cost is decreased, and the quality and artistic charm of the dyed fabric can be continuously ensured. The invention provides a dyeing process of the cashmere fabric. The phenomenon that the coloring rate after the cashmere fabric is dyed is low and the cashmere fabric is easy to fade in the use process can be apparently improved, and the patterns of thedyed fabric are fresher and more vivid.

Description

technical field [0001] The invention relates to the technical field of tie-dyeing printing, in particular to a combination process of digital printing of cashmere fabrics and traditional tie-dyeing. Background technique [0002] Tie-dyeing is an ancient folk traditional hand-made printing and dyeing process in my country. Tie-dyeing was called "zhaxie", "twisted valerian" or "twisted dyeing" in ancient times, commonly known as calico. Tie-dyeing is the process of tying, sewing, and knotting the fabric with needles and threads, so that the dye solution can freely penetrate and show a natural and colorful special effect. A dyeing method. Hu Sansheng, a native of the Yuan Dynasty, said in his "Zi Zhi Tong Jian Yin Zhu": "Picking, picking and knotting with thread, and then dyeing, once dyed, untie the knot, all knots are the original color, and the rest are dyed." , this passage clearly explains the traditional tie-dyeing process and process. [0003] With its unique artistic...
