Printing and dyeing method of multicolor jacquard cotton cloth

Abstract

The invention discloses a printing and dyeing method of multicolor jacquard cotton cloth. The printing and dyeing method comprises the following steps of S1, preshrinking a liquid caustic soda; S2, carrying out reduction dyeing; S3, dewatering; S4, sizing and shaping; and S5, calendaring to obtain the multicolor jacquard cotton cloth. According to the printing and dyeing method of the multicolor jacquard cotton cloth, before reduction dyeing, the liquid caustic soda is adopted for preshrinking, so that the white jacquard cotton cloth is shrunk, the density of a jacquard part is further increased, the density of a non-jacquard part is further reduced, the multicolor state is shown after dyeing, the boundaries between different colors are clear, and the colors in the same area unit are consistent, so that the color of the jacquard parts can be effectively highlighted, the jacquard has a concave-convex feeling; after liquid caustic soda preshrinking is completed, the jacquard cotton clothis cleaned with clear water, and the usage amount of vat dye in the vat dyeing process can be effectively reduced; and in addition, the colors of the same area units at different positions of the jacquard cotton cloth printed and dyed through the method are consistent, and the quality of the jacquard cotton cloth can be effectively improved.

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...

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 multi-color jacquard cotton cloth described in this embodiment, the first step, liquid alkali pre-shrinkage, the concentration of the liquid alkali solution adopted is 30%, immersion temperature is normal temperature, immersion time is 1 minute, after immersion is completed 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 g / liter, soak for 8 minutes, then add alkali-resistant vat dye, heat up, when the temperature reaches 45 degrees Celsius, start to add sodium hydrosulfite (the ratio of sodium hydrosulfite to water is 6 grams / liter) liter), then add glucose (the ratio of the amount of glucose to water is 1.2 g / l), and then add sodium hydrosulfate (the ratio of the amount of sodium hydrosulfate to water is 6 g / l) or reducing agent GR300 (the amount of reducing agent GR300 The...
