Problems solved by technology

[0002] In the printing and dyeing industry, the traditional printing and dyeing method for jacquard cotton is relatively mature, but the jacquard cotton printed and dyed by the existing method will have the following disadvantages: 1. The color of the jacquard cotton after printing and dyeing is relatively single, and the color of the jacquard and non-jacquard parts is close , it is impossible to realize the unevenness of the jacquard. 2. The color of the same area unit in different positions of the jacquard cotton cloth is inconsistent, and the color difference in the same area unit is relatively large
Due to the above shortcomings, the existing jacquard cotton products have low added value and low variety, making it difficult to make high-gloss jacquard cotton fabrics enter the high-end market

Embodiment 1

[0014] The printing and dyeing method of the multi-color jacquard cotton cloth described in this example: the first step, liquid alkali pre-shrinkage, the jacquard cotton cloth is immersed in the liquid alkali solution to shrink; the second step, reduction dyeing, the jacquard cloth after the first step treatment The cotton cloth is dyed with vat dyes, then reduced with oxidant, and finally the pH value is adjusted; the third step is dehydration, and the jacquard cotton cloth treated in the second step is dehydrated and dried; after the above three steps are completed, sizing and shaping: the dried The jacquard cotton cloth is sized and then shaped by a sizing machine; then calendered by a calender to obtain multi-color jacquard cotton cloth.

[0015] The jacquard cotton cloth adopts high-count yarn jacquard cotton cloth including more than 60 yarns.

[0016] For vat dyeing, first soak jacquard cotton cloth in water, the mass ratio of cloth to water is 1:30, add leveling agent...

Embodiment 2

[0019] The printing and dyeing method of the multi-color jacquard cotton cloth described in this embodiment, the first step, liquid alkali pre-shrinkage, the concentration of the liquid alkali solution used is 10%, the immersion temperature is 90 degrees Celsius, the immersion time is 60 minutes, and the immersion is completed Finally, wash the cloth with clean water.

[0020] The second step is reduction dyeing. First, the jacquard cotton cloth is soaked in water. The mass ratio of cloth to water is 1:30. The ratio of ether) and water is 0.8 g / liter, soak for 12 minutes, then add alkali-resistant vat dyes, heat up, and start to add hydrosulfite when the temperature reaches 45 degrees Celsius (the ratio of hydrosulfite to water is 4 grams / liter) liter), then add glucose (the ratio of the amount of glucose to water is 0.8 g / l), and then add sodium hydrosulfite (the ratio of the amount of sodium hydrosulfate to water is 4 g / l) or reducing agent GR300 (the amount of reducing agen...

Embodiment 3

[0026] The printing and dyeing method of the multi-color jacquard cotton cloth described in this embodiment, the first step, liquid caustic soda pre-shrinkage, the concentration of the used liquid caustic solution is 30%, immersion temperature is normal temperature, immersion time is 1 minute, after immersion is finished Rinse the cloth with clean water.

[0027] The second step is reduction dyeing. First, the jacquard cotton cloth is soaked in water. The mass ratio of cloth to water is 1:30. The ratio of ether) and water is 1.2 grams / liter, soaks for 8 minutes, then adds alkali-resistant vat dye, heats up, when temperature reaches 45 degrees Celsius, starts to add hydrosulfite (the ratio of hydrosulfite to water is 6 grams / liter) liter), then add glucose (the ratio of the amount of glucose to water is 1.2 g / liter), and then add sodium hydrosulfate (the ratio of the amount of sodium hydrosulfite to water is 6 g / liter) or reducing agent GR300 (the amount of reducing agent GR300...

Abstract

The invention designs a printing and dyeing method for multicolor jacquard cotton cloth. The method comprises: the first step, liquid alkali preshrinking; the second step, reduction and dyeing; the third step, dehydration; the fourth step, sizing and shaping; the fifth step, calendaring, thus obtaining the multicolor jacquard cotton cloth. According to the printing and dyeing method for multicolor jacquard cotton cloth, liquid alkali preshrinking is adopted before reduction and dyeing so as to make white jacquard cotton cloth shrunk, and the density of the jacquard part is further increased while the density of the jacquard-free part is further reduced, so that a multicolor state can be presented after dyeing, boundaries among different colors are distinct, and the color within one area unit is consistent. In this way, the color of the jacquard part can be made prominent effectively so as to endow the jacquard with a sense of concave-convex. After finishing liquid alkali preshrinking, the jacquard cotton cloth is cleaned with clear water, and the using amount of the reduction dye can be effectively reduced during reduction and dyeing. In addition, the jacquard cotton cloth treated with the printing and dyeing method of the invention can has a consistent color in a same area unit of different positions, thus effectively improving the quality of the jacquard cotton cloth.

Description

technical field [0001] The invention relates to the field of fabric printing and dyeing, in particular to a method for printing and dyeing multi-color jacquard cotton cloth. Background technique [0002] In the printing and dyeing industry, the traditional printing and dyeing method for jacquard cotton is relatively mature, but the jacquard cotton printed and dyed by the existing method will have the following disadvantages: 1. The color of the jacquard cotton after printing and dyeing is relatively single, and the color of the jacquard and non-jacquard parts is close , it is impossible to realize the concave-convex feeling at the jacquard. 2. The color of the same area unit in different positions of the jacquard cotton cloth is inconsistent, and the color difference in the same area unit is relatively large. Due to the above-mentioned shortcoming, the product added value of existing jacquard cotton cloth is low, and the variety is low, it is difficult to make high-gloss jac...
