Problems solved by technology

[0004] Direct printing is the main way of printing at present. It is a traditional processing technology that prepares commercially available dyes, pastes and additives into a printing paste with a certain viscosity, and then performs printing, drying, steaming and multi-channel washing; With the development of synthetic thickeners with high viscosity and low solid content, the amount of synthetic thickeners in printing pastes can be reduced. However, due to the poor compatibility between existing disperse dyes and synthetic thickeners, in order to obtain a certain Viscosity printing pastes still need to be equipped with synthetic thickener printing pastes with high solid content (such as 5-6%) to prevent the viscosity of the printing medium from decreasing
Due to the increase in the amount of synthetic thickeners in printing pastes, the utilization rate of direct printing dyes is low, and the printed fabrics need to be washed with a lot of water in the subsequent process to remove the floating colors on the surface of the fabrics, so as to improve the color fastness of polyester printed products and obtain softness. Therefore, the biggest disadvantage of direct printing is: due to the high content of solids in the printing paste, steaming treatment is required to complete the dyeing of the dye on the fiber; printed products have serious floating color and hard hand feeling, and post-washing treatment is required. Removing untransferred organic matter and dyes consumes a lot of water resources (accounting for 70% of the printing and dyeing process), and the discharge of wastewater is huge. The color of the wastewater is darker and the COD value is higher.
Existing pigment printing is a traditional processing technology that prepares commercially available paint, synthetic paste and additives (binders and crosslinking agents) into a printing paste with a certain viscosity, and then performs printing, drying, and hi

[0059] Example one

[0060] Combine 15g butyl acrylate, 3g ethyl acrylate, 3g acrylonitrile, 0.5g acrylic acid, 0.5g methacrylic acid, 0.5g N-methylol acrylamide, 0.5g 1,4-cyclohexanedimethanol diacrylate, 0.5g Bis-trimethylolpropane tetraacrylate, 0.5g emulsifier SP-80, 0.5g sodium dodecyl sulfonate, 0.5g isotridecyl alcohol polyoxyethylene ether (12) and 60g water mix, and fully Stir to form an emulsion. Dissolve 1 g of ammonium persulfate in 15 g of water at room temperature, and fully stir to form an initiator solution. Take half of the mass of the emulsion and half of the mass of the initiator solution into the reaction device of the three-necked biscuits, stir while heating, and raise the temperature to 70°C. When the temperature reaches 70°C, under stirring, slowly add a mixture of half the mass of the remaining emulsion and the mass of the initiator solution at the same time. The addition time is 100-120min. After the dripping is completed, continue stirring at 73°C ± ...

Abstract

The invention discloses a trace amount of printing paste and a preparation method and application thereof. The printing paste is composed of liquid disperse dyes, a function prepolymer, a synthetic thickener, a functional addition agent and water. The trace amount of prepared printing paste can finish printing of a polyester fabric on a conventional rotary screen printing machine or a screen printing machine; high-temperature processing is performed through a tentering heat setting machine, the temperature is 180-210 DEG C, the time is 45-120 seconds, and a polyester printing fabric is prepared. The printing paste is used for printing and is characterized in that the printing process is short, the fabric is soft in touch, afttertreatment is not needed, plenty of water resources are saved, plenty of energy consumption is reduced, and there is almost no waste water emission. Processing devices are all conventional devices, and the preparation method is a green printing processing technology.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, and in particular relates to a small amount of printing paste and its preparation method and application, which are used in the short process of polyester fabric printing, energy-saving and emission-reducing printing technology. Background technique [0002] With the development of the synthetic fiber industry, the mass production of various synthetic fibers and their blended fabrics puts forward new requirements for printing pastes. For example, the pigment printing of textiles, because the paint itself has no affinity, it needs the help of other substances to adhere to the surface of the fiber to form a film, and the color to form a pattern. In the textile printing and dyeing industry, powdery dyes are commonly used. When mixing pulp or preparing dye liquor, the dye dust is flying, which not only hinders environmental protection, but also often adheres to the ingredients use...
