Embodiment 1

[0019] (1) Select polyester-cotton 65:35 blended fabric (specification: 40×40 13396); prepare an acid treatment solution, add 50ml of concentrated sulfuric acid (98%) to 1L of water, cool to room temperature for later use;

[0020] (2) Grasping, kneading and pickling method at random: place the fabric flat on the table, start from any side or corner of the fabric, use both hands to randomly grasp and knead the whole fabric into a ball, and immerse it in the pre-prepared acid treatment solution. If the kneading is more detailed, the pattern after burnt-out will be smaller; otherwise, a larger pattern will be formed;

[0021] (3) Bake the acid-treated polyester-cotton blended fabric at 110°C for 120s, fully wash it with water, and use the beating method to wash off the brown or even black carbonized cotton fiber shavings on the fabric, and dry it;

[0022] (4) Dyeing: Boil dyeing in reactive dye solution, add a little salt after dyeing for 10 minutes, continue dyeing for 20 minu...

Embodiment 2

[0024] (1) Select polyester-cotton 65:35 blended fabric (specification: 45×45 13372); prepare an acid treatment solution, add 60ml of concentrated sulfuric acid (98%) to 1L of water, cool to room temperature for later use;

[0025] (2) Geometric folding pickling method: Fold the fabric into geometric figures in a certain way, and then immerse part of it in the acid treatment solution. Square folding method, triangular folding method and parallelogram folding method can be used. After that, a circular pattern with the pickling place as the center will be formed;

[0026] (3) Bake the acid-treated polyester-cotton blended fabric at 110°C for 90s, wash it with water fully, and use the rubbing method to wash off the brown or even black carbonized cotton fiber shavings on the fabric, and dry it;

[0027] (4) Dyeing: Boiling dyeing in reactive dye solution, add a little salt after dyeing for 10 minutes, continue dyeing for 20 minutes, add sodium carbonate to adjust the pH value of t...

Embodiment 3

[0029] (1) Select polyester-cotton 65:35 blended fabric (specification: 45×45 13372); prepare an acid treatment solution, add 30ml of concentrated sulfuric acid (98%) to 1L of water, cool to room temperature for later use;

[0030] (2) Brush acid method and needle acid injection method: use a brush or needle to dip or inhale the acid treatment solution, and brush it to the position where burnt-out is required or inject it to the position where burnt-out is required. The solution is brushed onto the edge of the folded fabric, and after carbonization, a burnt-out pattern along the hem will be formed;

[0031] (3) Bake the acid-treated polyester-cotton blended fabric at 110°C for 100s, wash it with water, and use a brushing method to wash off the brown or even black carbonized cotton fiber shavings on the fabric, and dry it;

[0032] (4) Dyeing: Boiling dyeing in reactive dye solution, add a little salt after dyeing for 10 minutes, continue dyeing for 20 minutes, add sodium carbo...

Abstract

The invention relates to a burnt-out printing / tie dyeing method of cotton-polyester blended fabric, which reforms and develops the traditional burnt-out printing process and tie dyeing process based on principles and technologies in the fields of modern esthetics, textile materials, textile processing chemistry, dyeing and finishing processes, and the like so as to maintain the traditional characteristics and be full of modern tastes. The burnt-out printing / tie dyeing fabric can be conveniently dyed in various colors by selecting the type and the color of various chemical dyes to meet the specific requirements and can have both clear patterns and exquisite chromatic halo effects, and stereoscopic effects on the surface of the fabric formed by a chemical method can not be weakened with the increase of the wearing time and the washing frequency. The method can be widely used in the fields of clothing, indoor soft decoration, fiber art, and the like, and has good generalization and application prospects.

Description

technical field [0001] The invention relates to the technical field of textile technology, in particular to a burn-out / tie-dyeing method of polyester-cotton blended fabrics. Background technique [0002] Tie-dyeing is a traditional folk printing and dyeing process in China. The world-renowned Chinese silk is inseparable from the superb tie-dyeing technology in ancient times. However, traditional tie-dye techniques have encountered bottlenecks in development in various places. Since the traditional tie-dyeing process originates from the original cultural and geographical environment of each place, the materials are mostly made of local woven fabrics (mostly cotton and linen fabrics) that are easily obtained locally, and the dyes are processed with bluegrass, madder, comfrey, soap bucket, gallnut, etc. The resulting vegetable dyes are mainly based on local ethnic groups, folk themes, animals and plants. They lack the flavor of the times, and the products are separated from th...
