Embodiment 1

[0009] Precoating liquid formula: (weight ratio)

[0010] Cationic resin (20% solid content): 40 parts

[0011] Silica 20 parts

[0012] Silicone dispersant 0.2 parts

[0013] Polyvinyl alcohol (18% solid content) 30 parts

[0014] 10 parts deionized water

[0015] Add a certain amount of deionized water into the reactor, add an appropriate amount of silicone dispersant, add silica powder while stirring at high speed, filter after stirring for 30 to 60 minutes, and then mix the dispersed silica aqueous solution, water-based cationic resin , polyvinyl alcohol aqueous solution, and deionized water were added to the reactor in turn and stirred fully for 30 minutes. After stirring for 10 minutes, let it stand still for use. After spraying the pre-coating liquid evenly on the surface of the cotton to be ink-jet printed, ink-jet printing was performed, and the printing was completed. Finally, bake at 130°C for 5 minutes to obtain the finished product.

Embodiment 2

[0017] Cationic styrene-acrylic resin (40% solid content) 30 parts

[0018] Light calcium carbonate 15 parts

[0019] Silicone dispersant 0.3 parts

[0020] 10 parts methyl cellulose

[0021] Polyvinyl alcohol aqueous solution (20%) 20 parts

[0022] 25 parts deionized water

[0023] Add a certain amount of deionized water into the reactor, add an appropriate amount of silicone dispersant, add light calcium carbonate powder while stirring at high speed, filter after stirring for 30 to 60 minutes, and then mix the dispersed light calcium carbonate aqueous solution, Cationic styrene-acrylic resin emulsion, methyl cellulose aqueous solution, polyvinyl alcohol aqueous solution, and deionized water were sequentially added to the reactor and stirred for 30 minutes. After stirring for 10 minutes, let it stand for use. Ink-jet printing is carried out after the pre-coating solution, and the finished product is obtained by baking at 120°C for 6 minutes after printing.

Embodiment 3

[0025] Cationic polyurethane resin (40% solid content) 40 parts

[0026] Silicon dioxide 10 parts

[0027] Silicone dispersant 0.2 parts

[0028] Polyvinyl alcohol aqueous solution (20%) 30 parts

[0029] 20 parts deionized water

[0030] Add a certain amount of deionized water into the reactor, add an appropriate amount of silicone dispersant, add silicon dioxide powder while stirring at high speed, filter after stirring for 30-60 minutes, and then mix the dispersed silicon dioxide aqueous solution and cationic polyurethane resin Emulsion, polyvinyl alcohol aqueous solution, and deionized water were added to the reactor in turn and stirred for 30 minutes. After stirring for 10 minutes, let it stand still for use. After spraying the pre-coating liquid evenly on the surface of the cotton to be ink-jet printed, ink-jet printing was carried out. After the end, bake at 100°C for 10 minutes to get the finished product.

Abstract

The invention relates to pre-coating solution for digital jet printing for cotton, belongs to the field of fabric printing, and provides the pre-coating solution for the digital jet printing of aqueous ink for cotton textiles. The cotton textiles processed by the pre-coating solution are subjected to jet printing and proper heat treatment to form printing products with clear colors and good wash fastness.

Description

technical field [0001] The invention relates to a digital printing precoating solution for cotton, which belongs to the field of textile chemical industry. Background technique [0002] Whether it is flat screen or rotary screen, traditional printing has disadvantages such as long production process, high labor intensity, and serious environmental pollution. In recent years, with the development of related technologies such as computers, materials, information and precision machinery manufacturing, digital inkjet printing technology has attracted more and more attention. [0003] Use scanners, digital cameras, digital cameras and other input means to input the pattern into the computer in digital form, after image software processing, and then use the digital inkjet printing machine controlled by the computer to directly spray the printing ink onto various fiber fabrics, Print out the required various patterns, this printing technology is called digital inkjet printing. ...
