Problems solved by technology

In order to improve the style and increase the added value, people have carried out a lot of special style finishing methods on the double-sided super soft fleece, such as burnt-out, cut flowers, embossing and other finishing methods that produce concave-convex three-dimensional effects on the wool surface, but these finishing methods all exist. Certain disadvantages, such as environmental protection problems, the problem of not durable enough patterns, the problem of high cost, etc.

Abstract

The invention discloses a production process of laser-carving double-faced super-flexible short flosses. The production process comprises the following steps: preparing a gray fabric; pre-setting; galling and combing on the front face; carrying out laser-carving; galling on the back face; setting; dyeing; carrying out water washing and softening; drying; combing on front and back faces and ironing and shearing; and setting a finished product. By virtue of a laser-carving method. An instantaneous high temperature of over 1000 DEG C is generated by using laser to melt polyester fibers, so that a concave-convex three-dimensional pattern is generated on the front face of the super-flexible floss and the floss on the front face is pulled to the back to form the super-flexible flosses with concave-convex three-dimensional patterns on two faces. The production process disclosed by the invention can be used for solving the problem that the quality in the large-scale production process is hard to control. And the ratio of top quality goods is improved from 80% to over 94% and the problem of determining the optimal process parameters of laser-carving is solved, so that the carving depth can be well controlled, and the problem that the back is non-uniformly galled is solved; the processing steps are shortened, the production rate is improved and the cost is lowered; the environmental pollution is reduced and the sewage treatment cost is lowered.

Description

technical field [0001] The invention specifically relates to a production process of laser-engraved double-sided supersoft short plush. Background technique [0002] Double-sided ultra-soft short plush, soft, comfortable, and warm. There are fluff on both sides, which is light, fluffy, and warm. It has changed the history that double-layer fabrics must be laminated by flame or glue. Disadvantages of high cost, not environmental protection, and poor hand feeling. Double-sided super soft short plush is mostly used in home textiles and pajamas. The front and back sides are covered with a layer of plump and fine fluff without revealing texture. It feels soft, fluffy, plump, and the suede is fine. In order to improve the style and increase the added value, people have carried out a lot of special style finishing methods on the double-sided super soft fleece, such as burnt-out, cut flowers, embossing and other finishing methods that produce concave-convex three-dimensional effect...
