Problems solved by technology

[0004] Although there have been reports on the washing-free dyeing process of polyester fabrics, the above-mentioned processes are all based on the dyeing and processing of conventional light and thin polyester fabrics, and there are no reports on the washing-free processing technology of heavy polyester fabrics, especially heavy blankets. For special styles such as fullness and napping, the non-washing dyeing process based on bonding and film formation will destroy the original style of the blanket

Embodiment 1

[0039] The washing-free high color fastness pad dyeing process of thick polyester blanket comprises the following steps:

[0040]1) Preparation of microcapsule-like liquid dye: put 100 g of dry powder disperse dye (red 4RL) filter cake in a ball mill, and ball mill it to a fine powder for 20 min at a high speed of 1200 r / min, then add 6 g of dispersant NNO and continue according to Ball mill at the above speed for 10 minutes, then add 10 g of polybutene powder and 3 g of glycerin under the control of the feeding speed of 30 g / min, continue to mill at the above speed for 30 minutes, add ultrapure water to the powder after ball milling, 2*10 4 Under the condition of HZ ultrasonication for 30 minutes, the solution was aided, and the concentration of the liquid dye with a mass concentration of 50% was prepared.

[0041] The liquid dye prepared by the above method is microcapsule-like, and the particle size distribution is between 300-820nm. Particle size distribution as figure...

Embodiment 2

[0048] Except that the concentration of the penetrant in the dyeing paste is different, the others are the same as in Example 1. Change penetrating agent concentration to be respectively 0,0.3,0.5g / L, carry out pad dyeing to polyester blanket according to the same pad dyeing process as embodiment 1, finish blanket dyeing; The fluffy and plump hand side) is tested for color index, and its color fastness is evaluated, and the results are shown in Table 1.

[0049] Table 1 Dyeing properties of blankets with different concentrations of penetrants

[0050]

[0051] It can be seen from Table 2 that the amount of penetrant has a significant impact on the level dyeing property of color paste dyed polyester blanket, and with the increase of penetrant amount, the level dyeing property gradually becomes better. When the penetrant amount is 0.1g / L (Example 1), the levelness reached the best; but increasing the amount of penetrating agent, its levelness gradually deteriorated. This is...

Embodiment 3

[0063] Except for the dyeing and baking temperature, the others are the same as in Example 1, and the baking color development temperature is changed to 170° C. respectively.

Abstract

The invention provides a washing-free high color fastness pad-dyeing process for heavy polyester blanket cloth, comprising the steps of: 1) preparing a microcapsule liquid dye, to be specific, ball-milling a powder dispersion dye, adding a dispersing agent, continue to carry out ball milling, adding polybutene powder and glycerol, continue to carry out ball milling, and adding water to obtain a microcapsule-like liquid dye; 2) preparing dyeing color paste; 3) padding; 4) pre-baking; and 5) developing color at 170-200 DEG C for 80 s-210 s. Compared with the prior art, the process enables polyester polymer macromolecules to be deeply soaked and dyed by virtue of high penetrability of nano particle size of the liquid dye particles; in addition, the pad-dyeing process designed by the inventionenables K / S value of the dyed cloth to be the highest, and color fastness and color vividness are excellent.

Description

technical field [0001] The invention belongs to the printing and dyeing process, and in particular relates to a washing-free high color fastness pad dyeing process for heavy polyester blanket. Background technique [0002] Polyester fabrics have the advantages of high strength, friction resistance, non-deformation, quick drying, and low cost, and are widely used in clothing, home textiles, and decorative fabrics. Among them, thick polyester blankets can be used to process carpets, blankets, plush toys, car interiors and other products. In recent years, the market demand has continued to be strong. According to statistics, from January to October 2018, my country exported 465 million blankets, earning more than 3.25 billion Dollar. [0003] The raw solution dyeing method has no cost-effective advantage in processing polyester blankets, and the proportion is very small. Dyeing is an important way to obtain colored blankets. At present, the dyeing process of polyester blankets...
