Production process of velvet containing spiral pile

Abstract

The invention discloses a production process of velvet containing spiral pile. The production process comprises the steps of preparing spiral pile warps, carrying out heat setting, performing weavingaccording to velvet tissues by adopting a double-shed rapier loom, and carrying out after-treatment such as velvet cutting and hydrolysis, so that the surface of the prepared velvet fabric has the spiral pile. The production process in the invention adopts wrapping yarns taking hydrolytic polyester yarns as core yarns to be subjected to processes of heat setting and hydrolysis, so that the surfaceof the velvet fabric can form the pile with a spiral shape, and the velvet fabric has three-dimensional vision, soft hand feeling and rich elasticity. The improvement that looping equipment needs tobe additionally arranged is avoided, the defect that water-soluble vinylon cannot be shaped at high temperature or the melting point would be shifted is overcome, the pile fastness of loop fabric in loop cutting and pile forming is improved, the disorder of piles which are bent due to different shrinkage rates and the piles of bent yarns is improved, the manufacturing is convenient, and the production process of the velvet containing the spiral pile is popular with people.

Description

technical field [0001] The invention relates to the technical field of velvet fabric production, and relates to a production process containing spiral pile velvet. Background technique [0002] The existing velvet varieties have become more and more perfect with the improvement of living standards, continuous improvement of equipment, and exquisite craftsmanship step by step. Especially a kind of loop velvet, due to the roughness of the loop and the fineness of the velvet, the visual contrast of the velvet combined with the two loops is refreshing and very attractive, but the velvet fabric must be looped, and the velvet loom It is necessary to modify and install a looping device, such as a shuttle box or a cloth-moving device for long beating and short beating, which is troublesome, especially for double-shed velvet looms, or weaving loops directly on towel looms , the fabric is cut and circled, but the pile of cut pile is not very firm. Recently, water-soluble vinylon has...

Problems solved by technology

Especially a kind of loop velvet, due to the roughness of the loop and the fineness of the velvet, the visual contrast of the velvet combined with the two loops is refreshing and very attractive, but the velvet fabric must be looped, and the velvet loom It is necessary to modify and install a looping device, such as a shuttle box or a cloth-moving device for long beating and short beating, which is troublesome, especially for double-shed velvet looms, or weaving loops directly on towel looms , the fabric is processed by cutting loops, but the fluff of the cut pile is not very firm

Recently, water-soluble vinylon has also appeared to assist looping, but the size of the loop is also limited, and it pollutes the environment to some extent, and the loops of the above loops are basically vertical

On the market, there is also a kind of two kinds of raw material yarns with different shrinkage rates that are entangled together to form buckling through humidification and heating, and there is also a kind of elbow yarn that is bent and then heat-set, but these two kinds of piles are relatively messy, so look It doesn’t fit well. Recently, as in the 2010105501163 patent, it is more cumbersome to shape the suede warp like knitting socks, and then disassemble it for weaving.
