Problems solved by technology

[0007] 1: Large pollution to the environment, more organic volatile gases and other harmful substances remain
[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

[0051] Such as Figure 1-4 Shown, the production technology of this automobile fabric two-point coating composite sponge comprises the steps:

[0052] A. Gluing: Put the water-repellent treated automotive fabric 1 on the unwinding frame of the double-point coating machine after the coating surface is judged, and put on the cloth, and process it on the coating surface through the double-point coating process. Double-point coating 2 and the coating amount of double-point coating 2 on the coating surface of automobile fabric 1 is 14-20 grams per square meter, that is, the automobile fabric with coating on one side is made; Wherein, the double-point coating Coating 2 is formed by the following steps:

[0053] a1. Choose a 30-40-mesh computer-designed double-point coated circular screen with a hole density of 150-200 holes / cm² and a hole diameter between 0.2-0.3 mm, and the wall thickness of the rotary screen is between 0.15-0.22 mm. ; Such dots are small and dense, the amount of...

Embodiment 2

[0077] 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:

[0078] In above-mentioned A step, described automobile fabric 1 is the warp-knitted automobile fabric of water-repellent treatment, and the warp-knitted automobile fabric with a door width of 156 centimeters and a specification of 170 grams per square meter is placed on the double Put the cloth on the unwinding rack of the dot coating machine, set the speed of the double dot coating machine at 22 m / min, and raise the temperature of the drying room to 180-185°C; choose 180 holes / square centimeter arranged randomly by computer , a round screen with a wall thickness of 0.18 mm and an aperture of 0.22 mm; select polyacrylate primer and adjust the machine parameters according to the solid content of polyacrylate of 4.0-4.5 grams per square meter of primer, and apply the polyacrylate base through the round screen The slur...

Embodiment 3

[0085] 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:

[0086] In the above-mentioned step A, the automobile fabric 1 is a water-repellent black and white interwoven and dyed warp knitted automobile fabric, and the warp knitted automobile fabric with a door width of 156 cm and a specification of 150 grams per square meter is judged to be good for painting. Put it on the unwinding frame of the double-point coating machine after layering 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; the computer random point arrangement is used 180 holes / square centimeter, wall thickness 0.18 mm and hole diameter 0.22 mm; choose polyacrylate primer and adjust the machine parameters according to the solid content of polyacrylate of 3.5-4 grams per square meter of primer, through the circl...

Abstract

The invention especially relates to a production process for a double-dot coating composite sponge used for an automobile fabric and an automobile composite fabric, belonging to the technical field of fabrics. The production process overcomes the problems of proneness to generation of pits, environment unfriendliness and the like in the prior art. The production process for the double-dot coating composite sponge comprises the following steps: A, gluing; and B, compounding. The automobile composite fabric is prepared by using the production process. The invention has the advantages that manufacturing cost is reduced; pits are prevented; peeling strength is improved; and environmental protection is better realized.

Description

technical field [0001] The invention belongs to the technical field of fabrics, and in particular relates to a production process of a double-point coated composite sponge for automobile fabrics and a composite fabric for automobiles. Background technique [0002] Warp-knitted automotive composite 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, and more smoke and toxic decomposition products will be generated, which will increase the organic volatile substances remaining in the co...
