A production method for multi-level color concave-convex offset silk velvet double-sided printing

Abstract

The invention discloses a production method for embossed offset-printed spun silk velvet duplex prints with multi-level colors. The method comprises the following steps of carding fuzzy fibers on the surface of a fabric to realize the untwisting and standing of the fuzzy fibers; performing natural luster finishing on the untwisted and standing fuzzy fibers in advance under the driving of a hauling woven belt, wherein a tail weaving feeding mode is adopted for the natural luster finishing, and the fuzzy fibers are all straightened; and offset-printing and drying the back surface of the fabric after natural luster finishing, printing the front surface of the fabric, washing the printed fabric, uniformly napping 30 to 50 percent of the fuzzy fibers on the front surface to the back surface by using a napping machine, performing carding, natural luster finishing and back surface nap cutting on the fuzzy fibers on the front and back surfaces, and performing finishing and width fixation on the fuzzy fibers on the surface of the fabric in a direction opposite to that of the naps to obtain a finished product. According to the method, the pre-treated fabric is subjected to back surface offset-printing and front surface printing for secondary printing treatment, so that the diversity of product styles is improved, a compound sewing process is eliminated, the labor intensity is reduced, and the defect rate of the product is reduced.

Description

technical field [0001] The invention relates to a printing and dyeing technology, in particular to a production method for multi-level color concave-convex offset printing silk velvet double-sided printing. Background technique [0002] The traditional printing and dyeing process combines the discharge printing technology and the cutting process to print the reverse side of the fabric. The discharge printing technology is to print a slurry containing a reducing agent or an oxidizing agent on the dyed fabric to destroy its ground color and partially expose it. White ground or colored patterns, but its reducing agent is corrosive to the flower roller, the selection range of dyeing materials is small, the color spectrum is incomplete, the cost is high, the production process is long and complicated, and the equipment occupies a lot of land; while the flower cutting process is to cut flowers by hand. Make the suede surface concave and convex, so that it has a three-dimensional ...

[0002] The traditional printing and dyeing process combines the discharge printing technology and the cutting process to print the reverse side of the fabric. The discharge printing technology is to print a slurry containing a reducing agent or an oxidizing agent on the dyed fabric to destroy its ground color and partially expose it. White ground or colored patterns, but its reducing agent is corrosive to the flower roller, the selection range of dyeing materials is small, the color spectrum is incomplete, the cost is high, the production process is long and complicated, and the equipment occupies a lot of land; while the flower cutting process is to cut flowers by hand. Make the suede surface concave and convex, so that it has a three-dimensional effect, but its labor intensity is high, and human operation errors are prone to occur, resulting in an increase in defective cut flower products

For the front printing of the fabric, the front wool is pulled to the back by fluffing the back, so that the front and back patterns are the same, but the color of the back graphic is lighter than the color of the front graphic, and the feel on the back is not as smooth and plump as the front
