preparation example Construction

[0027] The preparation process of the hyperbranched polyester thickener is as follows: put 1 part of pentaerythritol and 4 parts of bismethylol propionic acid into the reaction kettle, then put in the catalyst toluenesulfonic acid, react at 150°C for 1 hour, and then put in 8 parts Two methylolpropionic acid, the product is obtained after the reaction.

[0028] Wherein, the high-performance foam stabilizer is at least one of linear azobenzene polyoxyethylene ether PEP-600, azobenzene polyoxyethylene ether PIP-1000, and sodium lauryl sulfate.

[0029] The molecular structural formula of the linear azobenzene polyoxyethylene ether PEP-600 is shown in formula (II).

[0030]

[0031] The molecular structural formula of the azobenzene polyoxyethylene ether PIP-1000 is shown in formula (III).

[0032]

[0033] Wherein, the composite foaming agent is azodicarbonamide.

[0034] The present invention also provides a printing method using the above-mentioned water-free foam prin...

Embodiment 1

[0038] The non-washing foam printing color paste of the present embodiment 1 comprises the following components according to the mass percentage: nanometer liquid dispersion black MX-DBN 6%, PEP-600 0.5%, azodicarbonamide 1.5%, thickener 2%, remove Ionized water balance. The above-mentioned components were weighed according to the above-mentioned mass percentages, and all the components were stirred and mixed evenly to obtain the water-free printing color paste.

[0039] The method for carrying out foam printing using the water-free foam printing color paste of the present embodiment 1 comprises the following steps:

[0040] (1) Add the water-free foam printing color paste to the foaming machine for foaming to make printing foam. The printing foam is transported from the duct of the foaming machine to the foam applicator, and the foam applicator is used to accurately supply the liquid, and then the printing foam is sprayed with a scraper. uniformly distributed on the surface ...

Abstract

The invention discloses washing-free foam printing paste. The washing-free foam printing paste comprises the following components in percentage by mass of 1%-15% of nano liquid disperse dye, 0.5%-10% of a high-performance foam stabilizer, 0.3%-5% of a composite foaming agent, 3%-5% of a high-performance thickener and the balance of deionized water. The invention also discloses a printing method for printing by using the washing-free foam printing paste. According to the printing paste, the high-performance foam stabilizer is adopted, the half-life period of foamed foam is controlled to be in the optimal interval, the printing quality is improved, the dye liquid carrying amount of the formed foam is low, and printed patterns cannot permeate; and meanwhile, the printing paste adopts the nano liquid disperse dye and the high-performance hyperbranched thickener, so that the consumption of the thickener and the total consumption of the paste during printing are reduced, the subsequent washing procedure of printed patterns is omitted, the washing-free effect is achieved, and the purposes of saving water and energy to the maximum extent and improving economic benefits are achieved.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, and in particular relates to a water-free foam printing color paste and a printing method. Background technique [0002] Polyester is the largest and most widely used synthetic fiber variety in the world. Currently, polyester accounts for more than 60% of the world's synthetic fiber output. Disperse dyes for polyester dyeing are the most important category in the dye industry. Conventional disperse dyes require cumbersome and lengthy post-washing and reduction cleaning processes in the polyester dyeing or printing process in order to obtain better color fastness for fabrics. However, a large amount of printing and dyeing wastewater will be produced in the subsequent cleaning process, which contains a large amount of hydrosulfite, caustic soda and incompletely colored dyes; the wastewater is not only difficult to treat, but also easily pollutes the environment. Therefore, it ...
