Problems solved by technology

[0003] At present, most of the carpets on the market use the carpet surface to attach to the non-woven fabric or PVC substrate, but the non-woven fabric is relatively soft and has poor dimensional stability, so it is easy to produce edge warping during use. When PVC is used as the base material of the carpet, although the hardness of the carpet is improved, the user's comfort is not good due to the high quality of PVC.

Embodiment 1-5

[0063] A kind of preparation method of multi-level three-dimensional carpet is as follows:

[0064] S1. Make the regenerated fiber monofilaments into several regenerated fiber monofilaments, weave the regenerated fiber monofilaments of different lengths on the glass fiber mesh cloth by acupuncture method, and the regenerated fibers of different lengths form a three-dimensional pattern, thereby obtaining a three-dimensional carpet surface;

[0065] S2. Coating the modified water-based polyurethane on the bottom surface of the carpet surface, so that part of the modified water-based polyurethane penetrates into the bottom surface of the carpet surface, and the coating amount of the modified water-based polyurethane is 500-700g / ㎡ ;

[0066] S3, drying the modified water-based polyurethane to obtain a back glue layer;

[0067] S4. Apply modified water-based polyurethane on the side of the adhesive layer away from the carpet surface, and evenly adhere the anti-skid particles to th...

Abstract

The invention relates to the technical field of carpets, and particularly discloses a multi-layer three-dimensional carpet and a preparation method thereof. The multi-layer three-dimensional carpet sequentially comprises a carpet surface, a back gum layer and an anti-skid layer from top to bottom, wherein the back gum layer is prepared from modified waterborne polyurethane, the viscosity of the modified waterborne polyurethane is 1500 to 2000 mPa.s, the modified waterborne polyurethane is prepared from the following raw materials in parts by weight: 70-90 parts of waterborne polyurethane, 2-6 parts of epoxy resin, 3-10 parts of a cross-linking agent, 5-10 parts of a flame retardant, and 0.2-0.4 part of an antioxidant, the viscosity of the waterborne polyurethane ranges from 100 mPa.S to 300 mPa.S, and the viscosity of the epoxy resin is 8000 to 10000 mPa.S. According to the multi-layer three-dimensional carpet, the hardness and mechanical strength of the carpet are improved; and the modified waterborne polyurethane in the back gum layer is high in bonding strength and good in elasticity, and the hardness is slightly changed along with the temperature, so that the risk that the carpet surface and the anti-skid layer fall off from the back gum layer is reduced, the edge warping phenomenon of the carpet in the using process is reduced, and the carpet surface of the carpet is relatively flat and is not easy to wrinkle.

Description

technical field [0001] The application relates to the technical field of carpets, more specifically, it relates to a multi-layered three-dimensional carpet and a preparation method thereof. Background technique [0002] Carpet is a floor covering made of cotton, linen, wool, silk, grass yarn and other natural fibers or chemical synthetic fiber materials, which are knitted, cut or woven by hand or mechanically. It is one of the arts and crafts categories with a long history and tradition in the world. It has the advantages of reducing noise, heat insulation and decorative effects, improving foot feel, preventing slipping, and textile air pollution. [0003] At present, most of the carpets on the market use the carpet surface to attach to the non-woven fabric or PVC substrate, but the non-woven fabric is relatively soft and has poor dimensional stability, so it is easy to produce edge warping during use. situation; and when PVC is used as the base material of the carpet, alth...
