Abstract

The invention discloses a gravure roller coating and knife coating alternate printing technique, including: subjecting fabric to gravure roller printing prior to pre-drying, flattening with a presserroller under the temperature of 100-130 DEG C and the pressure of 2-2.5 MPa, drying, performing knife coating, and drying to obtain a finished product. The manufactured fabric has the differential andspecial printing features of dryness, coolness, softness and smoothness, has excellent color fastness, has effectively improved grade and added value and has improved competitiveness.

Description

technical field [0001] The invention relates to a gravure printing process, in particular to a gravure roller coating and knife coating cross printing process. Background technique [0002] Traditional printing is generally a processing method in which dyes such as reactive dyes or paints are directly printed on fabrics through a nickel mesh. The effect obtained by this printing method is a traditional flat effect, which lacks three-dimensionality and is not flexible enough. On this basis, gravure roll coating is produced. Gravure roll coating is a special printing method. Through materials and processing methods such as color paste, PU paste, pearlescent, and glitter sheets, a printing effect with obvious three-dimensional effect can be obtained. Combined with different The gravure process can achieve a three-dimensional effect with distinct layers, giving the pattern a "lifelike" visual experience. However, the printing effect of the existing fabrics obtained by gravure ...
