Preparation method of woven carpet without gumming process

Abstract

The invention discloses a preparation method of a woven carpet without a gumming process. A second coating layer is a hot-melt fiber-formed filament or a staple fibre yarn, a first coating layer is apolyester fiber filament or a staple fibre yarn, the second coating layer accounts for 20%-50% of the total mass of a composite yarn, the first coating layer accounts for 10%-15% of the total mass ofthe composite yarn, the balance is a core yarn, and a pile weft yarn is obtained by adopting the manner. When the non-adhesive carpet is produced by using a hot-melt copolyester fiber as a bonding material in combination with the pile yarn made of a polyester fiber, the melting occurs when the hot-melt copolyester fiber is heated to be higher than the melting point in a hot pressing process, the conformation of a fiber macromolecular chain is changed, the whole macromolecular chain slips through the transition of chain segments, viscous flow occurs, the pile and weft yarns as well as the weftyarns and warp yarns are effectively solidified after curing, and the pull strength of the pile and the shape retention and dimensional stability of the carpet are enhanced, so that the gumming process in the carpet preparation process is omitted, and the produced carpet is more environmentally friendly.

Description

technical field [0001] The invention relates to the field of household articles, in particular to a preparation method of a woven carpet without a back glue process. 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 plu...

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 a
