Problems solved by technology

[0002] The manufacture method of carpet also does not have relevant literature to report at present, and, although existing carpet on the market is simple in structure, production cost is low, but has following shortcoming:
[0003] 1. Poor flatness, stable size and easy deformation;
[0004] 2. Can not be water-proof, waterproof, easy to breed mold;
[0005] 3. The product itself is hard and cannot be used as a coil

Embodiment 1

[0030] First, the first layer of yarn balls 1 (which can be nylon filaments, polyester staple non-woven short filaments or nylon PP flat filaments) is combined with the second layer of base fabric 2 by conventional tufting or needle-making methods; At 120°C, the third layer of waterproof layer 3 (which can be modified asphalt) is compounded on the bottom surface of the second layer of base fabric 2; brick) on the bottom surface of the cooled third layer of waterproof layer 3, then preheat the bottom surface of the fourth layer of shaping layer 4 to 15°C, and then apply polyurethane raw materials to the aforementioned preheated fourth layer at 0°C. The bottom surface of the layer shaping layer 4 forms the fifth layer of polyurethane foam layer 5; finally, the sixth layer of non-slip 6 (which can be short-filament needle-punched non-woven fabric, polyester or polypropylene fiber) is compounded on the fifth layer of polyester foam layer 5 on the bottom surface, cooling to obtain ...

Embodiment 2

[0032] The temperature in the second step is set at 180°C, the preheating temperature in the fourth step is 50°C, and the coating temperature is 50°C. The rest are the same as step 1, and the environment-friendly soft carpet of the present invention is also obtained.

Embodiment 3

[0034] The temperature in the second step is set at 150°C, the preheating temperature in the fourth step is 25°C, and the coating temperature is 20°C. The rest are the same as step 1, and the environmental protection soft floor carpet of the present invention is also obtained.

Abstract

The production process of environment protecting soft bottom carpet includes the following steps: combining the first layer of yarn with the second base cloth layer via conventional tufting or knitting; compounding the third waterproof layer to the bottom of the second base cloth layer at 120-180 deg.c for 1-30 min; spreading the fourth setting layer to the bottom of the third layer; preheating the bottom of the fourth setting layer to 15-50 deg.c and painting polyurethane at 0-50 deg.c to form the fifth foamed polyurethane layer; and finally compounding the sixth skidproof layer to the bottom of the fifth layer and cooling. Through the simple process, high quality skidproof, waterproof, silent and pressure-resistant carpet may be produced.

Description

technical field [0001] The invention relates to a carpet manufacturing technology, in particular to a manufacturing method of an environment-friendly soft-bottomed carpet. Background technique [0002] The manufacture method of carpet also does not have relevant literature to report at present, and, although existing carpet on the market is simple in structure, production cost is low, but has following shortcoming: [0003] 1. Poor flatness, stable size and easy deformation; [0004] 2. Can not be water-proof, waterproof, easy to breed mold; [0005] 3. The product itself is hard and cannot be used as a coil. [0006] Therefore need a kind of new carpet manufacturing method to produce better carpet. Contents of the invention [0007] The purpose of the present invention is to overcome the defective of above-mentioned prior art, a kind of novel environment-friendly soft bottom carpet manufacturing method is provided. [0008] The object of the present invention is achie...
