preparation example Construction

[0041] A preparation method of the above-mentioned molded cushion, the preparation method comprises the following steps in sequence:

[0042]Step 1: Lay down the exterior coating material 2 on the lower mold first, and then lay honeycomb cotton in the middle of the lower exterior coating material 2. Spray hot-melt adhesive or hot-melt powder on the edge where the edge portion 4 of the cushion is preformed, and then spread the upper surface coating material 1 on the honeycomb cotton to form a blank body, and the upper surface coating The positions of material 1 and lower surface coating material 2 correspond to each other;

[0043] Step 2: Start the upper mold and the lower mold to hot press the blank body. During hot pressing, the air pressure in the space surrounded by the upper mold and the lower mold is lower than atmospheric pressure. The temperature of hot pressing is 180-230°C. The pressing time is 20-180 seconds;

[0044] Step 3: Cool after the hot pressing is complet...

Embodiment 1

[0061] see figure 1 - image 3 , a molded seat cushion, comprising an upper surface covering material 1, a lower surface covering material 2 and an inner container 3, an inner liner is arranged between the middle part of the upper surface covering material 1 and the middle part of the lower surface covering material 2 liner 3, and the edges of the upper surface covering material 1 and the lower surface covering material 2 are connected to each other to form the cushion edge 4;

[0062] The inner liner 3 is honeycomb cotton, the upper surface covering material 1 and the lower outer surface covering material 2 are woven fabrics, knitted fabrics, non-woven fabrics or leather; the inner liner 3 is a formed three-dimensional structure, The bottom surface of the middle part of the upper surface covering material 1 is connected to the top surface of the inner container 3, and the bottom surface of the inner container 3 is connected with the top surface of the middle part of the lowe...

Embodiment 2

[0069] Basic content is the same as embodiment 1, the difference is:

[0070] On the product—both the top surface of the middle part of the upper surface covering material 1 and the bottom surface of the middle part of the lower surface covering material 2 are provided with printing or one of them is provided with printing.

[0071] In the preparation method——in the second step, before hot pressing the blank body, transfer printing paper is provided on the top and bottom surfaces of the blank body, or one of the two is provided with transfer printing paper. The dye on the pattern in the transfer printing paper is heat-treated to transfer the dye to the blank body to form a print; in the third step, after the heat pressing is completed, the printed transfer printing paper needs to be removed.

[0072] When printing, it can be printed on the top surface and the bottom surface of the cushion at the same time, or it can be printed on only one of the top surface or the bottom surfa...

Abstract

The invention discloses a compression-molded cushion. The compression-molded cushion comprises an upper outer surface coating material, a lower outer surface coating material, and a liner manufactured by honeycomb cottons therebetween; the edges of the upper and lower outer surface coating materials are connected as cushion edge parts; the liner is a molded three-dimensional structure; the middle parts of the upper and lower outer surface coating materials are respectively connected with the top and bottom surfaces of the liner; a concave-convex three-dimensional structure of the cushion is embodied by concave-convex three-dimensional structures on the outer surface coating materials and the liner; during preparing, the outer surface coating materials and the honeycomb cottons are once molded by the mold to obtain the cushion; and the printing can be also considered. The compression-molded cushion is higher in preparation efficiency, lower in production cost, higher in combination firmness and better in environmental protecting performance, achieves the advantages of high elasticity and resilience, and is high in third dimension, excellent in support performance and excellent in beauty.

Description

technical field [0001] The invention relates to a seat cushion and a preparation method thereof, belonging to the field of nonwoven fabrics, in particular to a molded seat cushion and a preparation method thereof, which are particularly suitable for improving preparation efficiency and reducing production costs. Background technique [0002] Cushions are fiber products that people come into contact with almost every day. With the rapid development of my country's economy and society, people's living standards are improving day by day. Not only do they have higher requirements for the material and comfort of the cushions, but they also have higher requirements for the aesthetics and decoration of the cushions. come higher. Cushions are used in a wide range of applications, such as car cushions, sofa cushions, seat cushions, etc. [0003] The structure of the cushion is generally composed of outer covering material and filling material, and its shape is generally square, round...
