Production method of woven carpet with no latex

Abstract

The invention discloses a production method of a woven carpet with no latex. A second covering layer is made with hot-melt fiber filaments or staple yarns; a first covering layer is made with high-density polyethylene fiber filaments or staple yarns; the second covering layer accounts for 20-50% of total mass of composite yarn; the first covering layer accounts for 10-15% of the total mass of thecomposite yarn; the balance is core yarns; pile wefts are therefore produced. During the production of a no-gum carpet with hot-melt low-density polyethylene fiber as an adhesive material, pile yarnsare made in conjunction with nylon fiber or wool; the hot-melt low-density polyethylene fiber melts down when heated to above its melting point in a hot pressing step, and fiber macromolecular chain conformation varies; segmer transition allows the whole macromolecular chain to slide, a viscous flow occurs, piles, wefts and warps are effectively fixed after solidifying, pull-out strength of the piles is enhanced, and shape-maintaining property and dimensional stability are enhanced for the carpet; therefore, the gumming step in the carpet production process is omitted, so that the carpet produced is more environmentally friendly.

Description

technical field [0001] The invention relates to the field of household articles, in particular to a method for preparing a latex-free woven carpet. Background technique [0002] With the improvement of modern living standards, the requirements for the comfort, fashion and environmental protection of some public places and home decoration are also getting higher and higher. The utilization rate of carpets in some public places and home decoration accounts for a large part. Carpets have the function of heat preservation and regulation. Large-area carpets can reduce the heat lost through the ground in the room, block the invasion of cold air on the ground, and make people feel warm and comfortable. At the same time, it has a sound-absorbing function. The rich texture of the carpet and the surface of the plush tufts have a good sound-absorbing effect, and can properly reduce the impact of noise. Since the carpet is a fabric rich in elastic fibers, it has a plump, thick, and sof...

AI Technical Summary

Problems solved by technology

Woven Wilton carpets are made by interweaving warp yarns, weft yarns, and pile yarns, and are finished by subsequent processes such as gluing, shearing, etc., so that the warp yarns, weft yarns, and pile yarns are mechanically bonded. It is also made by interweaving warp yarn, weft yarn and pile yarn, and then finishing through gluing, shearing and other processes. In the gluing process, organic solvents are needed to dissolve and dilute the glue. Therefore, in the gluing process, there are the following problems: ⑴ During the gluing process, volatile harmful gases pollute the environment and affect the health of workers; (2) The gluing and drying and curing process is long and takes a long time, which limits the production speed, the equipment occupies...
