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 no-wash high color fastness pad dyeing process of heavy polyester blanket fabric includes the following steps:

[0040]1) Preparation of microcapsule-like liquid dyes: put 100g of dry powder disperse dye (red 4RL) filter cake in a ball mill, grind it to fine powder for 20min at a high speed of 1200r / min, add 6g of dispersant NNO and continue to follow The above-mentioned speed was ball-milled for 10min, then controlled at a feeding speed of 30g / min, and then added polybutene powder 10g and glycerin 3g, continued to be ball-milled at the above-mentioned speed for 30min, added ultrapure water to the ball-milled powder, under ultrasonic 300W, 2*10 4 Under the condition of HZ ultrasonic for 30 minutes, the microcapsule-like liquid dye with a concentration of 50% by mass was prepared.

[0041] The liquid dye prepared by the above method is a microcapsule-like type, and the particle size distribution is between 300-820 nm. The particle size distribution is figure 2 As...

Embodiment 2

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

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

[0050]

[0051] It can be seen from Table 2 that the amount of penetrant has a significant effect on the levelness of color paste-dyed polyester blankets, and with the increase of the amount of penetrant, the levelness gradually improves. When the amount of penetrant is 0.1g / L (Example 1), the levelness reaches the best; however, as the amount of the penetrant increases, the levelness gradually deteriorates. This is mainly be...

Embodiment 3

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

Abstract

The invention provides a water-free high color fastness pad dyeing process for heavy polyester blankets, comprising the following steps: 1) preparation of microcapsule-like liquid dyes: after ball-milling powder disperse dyes, adding dispersants to continue ball-milling, and then adding Polybutene powder and glycerin, continue ball milling, add water to obtain microcapsule-like liquid dye; 2) prepare dyeing paste; 3) padding; 4) pre-bake; ~210s. Compared with the prior art, the present invention relies on the high penetrability of the nano-particle size of the liquid dye particles to realize the deep penetration dyeing of the polyester polymer polymer; in addition, the pad dyeing process designed by the invention enables the dyeing fabric to have the highest K / S value. , excellent color fastness and color brightness.

Description

technical field [0001] The invention belongs to a printing and dyeing process, and in particular relates to a water-free high color fastness pad dyeing process for heavy polyester blankets. Background technique [0002] Polyester fabric has the advantages of high strength, friction resistance, non-deformation, quick drying and low cost, and is widely used in clothing, home textiles, decorative fabrics and other fields. Among them, heavy 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's export of blankets reached 465 million, earning over 3.25 billion foreign exchange. Dollar. [0003] The dope dyeing method does not have the advantage of cost-effectiveness, and the proportion is very small. Dyeing is an important way to obtain colored blankets. At present, the dyeing and processing of poly...
