Problems solved by technology

For a long time, the traditional polyester silk calico has been subjected to high-temperature steaming and then reduction cleaning. After all the paste, floating color, and impurities on the surface of the gray cloth are cleaned, the finishing can be carried out. A large amount of cleaning wastewater is virtually produced, and the wastewater Disposal creates higher costs and efflux pressure
Therefore, it is considered to reduce the washing after printing, but without washing, the residual paste on the cloth surface will make the finished product feel harder, the more paste, the harder the hand feel, and the increase of paste will also affect the water pressure resistance of the subsequent coating index
The existing printed fabrics have not undergone depaste and surface floating color reduction cleaning, which will have a serious impact on the color fastness in the subsequent waterproof finishing and coating finishing

Embodiment

[0015] A disperse dye non-steaming and cleaning printing process, using non-washing dyes for rotary screen roller printing, non-washing dyes include: dye 3-4%, non-washing paste 2% and the rest of water, non-washing paste includes: acrylic acid 42% polymer, 4% stabilizer, 4% emulsion dispersant and 50% solvent naphtha, the viscosity of printing paste is controlled at 30000cps.

[0016] The pressure roller of rotary screen cylinder printing is a heatable pressure roller. The heating range of the pressure roller covers the boundary of this printing. The heating temperature of the pressure roller is controlled at 60°C, and the printing speed is controlled at 50m / min. . When printing, the pressure between the printing cylinder and the pressure roller is controlled at 0.3MPa, the slurry suction rate is 50kg / h, the permeability is ≥85%, and the sizing rate is ≥3%. A warming belt is embedded on the surface of the pressure bearing roller, and a heating pipeline is arranged inside the...

Abstract

The invention relates to a disperse dye steaming-washing-free cleaning printing process. A washing-free dye is used for rotary screen roller printing, and comprises 3 to 4 percent of a dye, 2 percent of a washing-free paste and the balance of water; the washing-free paste comprises 42 percent of an acrylic polymer, 4 percent of a stabilizer, 4 percent of an emulsion dispersant and 50 percent of solvent oil; the viscosity of a printing paste is controlled to be 30000 cps; a pressure-bearing roller for rotary screen roller printing is a heatable pressure-bearing roller, the heating range of the pressure-bearing roller covers the boundary of the printing, the heating temperature of the pressure-bearing roller is controlled to be 60 DEG C, and the printing speed is controlled to be 50 m / min; and the drying temperature after printing is controlled at 180 DEG C. The washing-free paste has certain viscosity, and the pressure-bearing roller is a heatable pressure-bearing roller, so that the color paste for printing each time is quickly dried, and permeation caused by the capillary effect of a fabric can be partially counteracted, thereby ensuring the contour smoothness of patterns, preventing the paste, surface dyeing and impurities from being adhered to the surface of the fabric, avoiding ageing and washing, and reducing various consumptions used in the reduction cleaning process.

Description

technical field [0001] The invention belongs to the field of printing, and in particular relates to a disperse dye non-steaming and cleaning printing process. Background technique [0002] The base fabrics are all white or other single colors, and the visual effect is low. Therefore, people have developed printed fabrics. Printed fabrics are a kind of fabric with patterns, and its patterns are various, beautiful and fashionable. It not only eliminates the singleness of pure color fabrics, but also greatly enriches people's material life enjoyment. [0003] As the state monitors the environmental protection production of the printing and dyeing industry more and more strictly, energy conservation and emission reduction has become the focus of the long-term development of the printing and dyeing industry. For a long time, the traditional polyester silk calico has been subjected to high-temperature steaming and then reduction cleaning. After all the paste, floating color, and ...
