A kind of preparation method of latex-free machine-woven carpet

technical field

The invention belongs to the field of household products, and in particular relates to a preparation method of a latex-free woven carpet.

Background technique

With the improvement of modern living standards, the requirements for comfort, fashion, and environmental protection of home decoration are also getting higher and higher. The utilization rate of carpets in 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 and comfort. Because the carpet is a fabric rich in elastic fibers, it has a plump, thick, and soft texture. , so it will have better resilience when walking on it, and it feels comfortable and soft. At the same time, the carpet has an aesthetic function, and the texture is plump. After the carpet with a gorgeous appearance is laid, the ground can look dignified and rich, and an excellent decorative effect can be obtained. There are many types of carpets, such as wool carpets, chemical fiber carpets, leather carpets, rubber carpets, natural fiber carpets and so on. Each has its own characteristics and advantages.

Woven Wilton carpets are made by interlacing warp yarns, weft yarns, and pile yarns, and finishing through subsequent processes such as gluing and shearing. Woven Axminster carpets are also made by interweaving warp, weft and pile yarns, and then finishing by gluing, shearing and other processes. The use of latex coatings poses some problems in the manufacture and recycling of carpets, namely waste water disposal problems and unpleasant odours. Latex adhesive layers are sometimes mixed with calcium carbonate to reduce costs, but this poses a problem when the waste is incinerated with non-flammable fillers.

After the three yarns of warp, weft and pile are interwoven, they are heated to melt the hot-melt fibers, bond the pile, cool and solidify and post-process to obtain the carpet.

The core yarn is various filament yarns or short fiber yarns meeting the needs of the carpet.

The melting point of the hot-melt fiber is 110-170°C, which is lower than the softening temperature of other fibers used in the carpet.

The hot-melt fiber is selected from polypropylene, polyamide fiber, polyester fiber, polyolefin fiber, polyvinyl chloride fiber or combinations thereof.

The solvent is ethanol, and the dispersant is PVP.

The heating method is hot air heating, hot roller heating, or far infrared heating.

The carpet prepared by the method.

Compared with the prior art, the present invention has the advantages of not using the traditional latex adhesive layer, solving the problems of waste water pollution and air pollution in the process of producing and recycling carpets, and being conducive to environmental protection, and adopting nano-reinforced materials to enhance the strength of the carpet. Wear resistance, and the reinforcing material is prepared in the form of slurry, which improves the degree of dispersion, reduces the degree of agglomeration, and effectively ensures the uniform performance of the carpet.
