Digital paint printing technology

Abstract

The invention discloses a digital paint printing technology, which is characterized by comprising following steps: (1) pretreatment: subjecting semi-finished cloth to a online counterpoint spray printing pretreatment: spraying a pretreatment liquid on cloth according to the shade of a pattern in a counterpoint spray printing mode; (2) drying: drying the preprocessed cloth; (3) spray printing a paint: spray printing a paint on the surface of dried cloth; (4) post treatment: adopting a wet counterpoint spray printing post treatment liquid, and spray printing the post treatment liquid on the cloth according to the shade of the pattern; (5) drying and baking: baking the cloth for 3 to 5 minutes at a temperature of 150 to 170 DEG C by a drying-baking integrated machine; and (6) moulding and stretching: softly stretching the cloth by a moulding machine.

Description

technical field [0001] The invention relates to the field of textile digital printing equipment, in particular to a digital paint printing process. Background technique [0002] In the textile printing of the prior art, pigment printing has been widely used in traditional and digital printing, but no matter which printing has certain shortcomings, it is mainly manifested in the poor hand feeling of pigment printing, the fastness to washing, and the poor fastness to wet and dry. , the hair color also has limitations, so it is often difficult to meet the requirements, and the technology of digital paint printing has been developed for many years. It has the advantage of paint ink, that is, it does not need finishing, so there is no sewage problem, which is beneficial Environmental protection requirements, but the above problems also exist. At present, digital pigment printing has poor hand feeling, poor hair color, various washing fastness, dry and wet fastness can not meet th...

[0002] In the textile printing of the prior art, pigment printing has been widely used in traditional and digital printing, but no matter which printing has certain shortcomings, it is mainly manifested in the poor hand feeling of pigment printing, the fastness to washing, and the poor fastness to wet and dry. , the hair color also has limitations, so it is often difficult to meet the requirements, and the technology of digital paint printing has been developed for many years. It has the advantage of paint ink, that is, it does not need finishing, so there is no sewage problem, which is beneficial Environmental protection requirements, but the above problems also exist. At present, digital pigment printing has poor hand feeling, poor hair color, various washing fastness, dry and wet fastness can not meet the requirements, and the process is more complicated and not energy-saving enough.
