Problems solved by technology

[0007] 1: Large environmental pollution, organic volatile and other harmful residues
[0008] 2: In order to remove the smell, additional baking and degassing treatment is required, which also pollutes the air
[0009] 3: When the flame is compounded, the flame will burn the sponge itself with a thickness of about 2-3mm, which is also a waste
[0010] 4: Flame compounding is prone to quality problems such as carbon black pollution
[0011] 5: High requirements on combustion nozzle and airflow control, easy to cause quality problems
Therefore, the automotive fabric composite field is basically unable to adopt

Embodiment 1

[0077] In the above step A, the water-repellent automotive fabric 2 is a gray warp-knitted water-repellent automotive fabric. After the gray warp-knitted water-repellent automotive fabric with a door width of 156 cm and a specification of 145 g / square meter is judged to be coated Put it on the unwinding frame of the double-point coating machine and put on the cloth. The speed of the double-point coating machine is set at 22 m / min, and the temperature of the drying room is raised to 180-185 °C; 180 holes arranged randomly by the computer are selected. / square centimeter, a wall thickness of 0.18 mm and a hole diameter of 0.22 mm, that is, a cp180 rotary screen; select polyacrylate primer and adjust the machine parameters according to the solid content of polyacrylate of 3.5-4.0 g / square meter of primer, The polyacrylate primer is transferred through the rotary screen and dot-coated on the coating surface of the gray warp-knitted water-repellent automotive fabric. The polyacrylat...

Embodiment 2

[0088] The structure and principle of this embodiment are basically the same as those of Embodiment 1, so they will not be repeated here. The difference lies in:

[0089] In the above-mentioned step A, the water-repellent automotive fabric 2 is a warp-knitted water-repellent automotive fabric, and the warp-knitted water-repellent automotive fabric with a width of 156 cm and a specification of 180 g / square meter is placed on the coated surface after being judged. Put the cloth on the unwinding rack of the double-point coating machine, set the speed of the double-point coating machine at 20 m / min, and raise the temperature of the drying room to 180-185°C; choose 180 holes / square arranged randomly by computer Centimeter, wall thickness 0.18 mm and hole diameter 0.22 mm; select polyacrylate primer and adjust the machine parameters according to the solid content of polyacrylate of 4.0-4.5 g / m2 of primer, pass the polyacrylate base through the cylinder The slurry is transferred and ...

Embodiment 3

[0097] The structure and principle of this embodiment are basically the same as those of Embodiment 1, so they will not be repeated here. The difference lies in:

[0098] In the above-mentioned step A, the water-repellent automotive fabric 2 is a warp-knitted water-repellent automotive fabric, and the warp-knitted water-repellent automotive fabric with a width of 156 cm and a specification of 160 g / square meter is placed on the coated surface after being judged. Put the cloth on the unwinding frame of the double-point coating machine, set the speed of the double-point coating machine at 22 m / min, and raise the temperature of the drying room to 180-185°C; choose 180 holes / square arranged randomly by computer Centimeter, wall thickness 0.18mm and hole diameter 0.22mm; choose polyacrylate primer and adjust the machine parameters according to the solid content of polyacrylate of 3.5-4.0 g / m2 of the primer, and pass the polyacrylate base through the cylinder The slurry is transferr...

Abstract

The invention belongs to the technical field of fabrics and in particular relates to a three-layered composite automotive interior fabric and a production process thereof, and aims at solving the problems in the prior art that pocks are easy to generate and the fabric is not environment-friendly and the like. The three-layered composite automotive interior fabric comprises sponge, a water-repelling automotive fabric and a non-woven fabric; a first double-point coating is arranged on one face of the water-repelling automotive fabric and the water-repelling automotive fabric is compounded on one face of the sponge through the first double-point coating; a second double-point coating is arranged on one face of the non-woven fabric and the non-woven fabric is compounded on the other face of the sponge through the second double-point coating. The production process of the three-layered composite automotive interior fabric comprises the following steps: A, gluing; B, compounding. The three-layered composite automotive interior fabric and the production process thereof have the advantages that the manufacturing cost can be reduced and the pocks can be avoided; the peeling strength can be improved and the fabric is more environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of fabrics, in particular to a three-layer composite automotive interior fabric and a production process thereof. Background technique [0002] Warp-knitted automotive interior fabrics are widely used in automotive interiors, and the parts with higher requirements are pillars, door panels and ceilings. The warp-knitted automotive fabrics on the ceiling generally need to be laminated with the PUR sponge bottom layer before being laminated or laminated with the laminated bottom plate. The composite method of PUR sponge and fabric is to burn and melt the surface of sponge with flame and then immediately composite with automotive fabric. [0003] The surface of the sponge will be burnt and melted during flame compounding, which will generate more smoke and toxic decomposition products, which will increase the organic volatile substances remaining in the compound, which is very unfavorable for new cars to preven...
