Preparation method of latex-free woven carpet

Abstract

The invention discloses a preparation method of a latex-free woven carpet. According to the preparation method, filament yarn formed by hot-melting fibers or staple fiber yarn is used as a second cladding layer, polyester fiber filament yarn or staple fiber yarn is used as a first cladding layer, the mass of the second cladding layer accounts for 20-50% of the total mass of composite yarn, the mass of the first cladding layer accounts for 10-15% of the total mass of the composite yarn, the balance is core yarn, and in this way, pile weft yarn is prepared. As the latex-free carpet is produced by using hot-melting copolymer fibers as a bonding material, and the pile yarn prepared from nylon fibers or wool is cooperatively used, the hot-melting copolymer fibers are molten when heated to the melting point of the hot-melting copolymer fibers or above in the hot-press process, the fiber macromolecular chain conformation is changed, through transition of chain segments, the whole macromolecular chain is glided and viscously flows, and after solidification, pile and weft yarn are effectively solidified, and the weft yarn and warp yarn are effectively solidified. Accordingly, the pulling-out force of the pile is enhanced, and the shape preserving performance and the size stability of the carpet are improved, so that the backing process in the carpet preparation process is omitted, and the carpet obtained by using the method 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 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 so...

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 large space, the amount of glue used is large, and the energy consumption is high. The production cost of the carpet is lowered; (3) the traditional carpet adopts the method of applying glue on the back of the embryo carpet, and the glue needs to be infiltrated into the pile yarn through the embryo carpet base cloth. This leads to problems such as insufficient pull-out strength, poor dimensional stability, and easy deformation of the pile yarn

At the same time, in order to reduce the cost and improve the stiffness of the carpet, the glue bonding layer is generally mixed with calcium carbonate during the gluing process. The problem brought by this method is that it is not easy to reuse, and when the waste is burned, the waste contains flame retardant filler
