Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of composite fabric, specifically relates to a ventilative composite sofa fabric. BACKGROUND

[0002] The composite fabric is a new type of material formed by bonding one or more layers of textile material, non-woven material and other functional materials, which is suitable for making sofas, clothes and other textiles and is one of the indispensable fabrics for people's home life.

[0003] The existing composite fabric for the surface of the sofa is bonded by glue, which results in poor overall ventilation. UTILITY MODEL CONTENT

[0004] The utility model discloses a ventilative composite sofa fabric, can guarantee the overall composite strength under the premise, and the overall ventilation is good.

[0005] The utility model discloses a ventilative composite sofa fabric, including no. 1 fabric layer, no. 2 fabric layer, sponge layer, the upper end face of sponge layer is intervally provided with the section arc no. 1 strip shape convex, the position of the lower end face of sponge layer corresponds no. 1 strip shape convex and is provided with the section arc no. 2 strip shape convex, the upside of sponge layer is provided with no. 1 fabric layer, the downside of sponge layer is provided with no. 2 fabric layer, no. 1 strip shape convex, no. 2 strip shape convex are immersed in the adhesive, and no. 1 fabric layer and sponge layer are fixed by the adhesive in no. 1 strip shape convex and are bonded, and no. 2 fabric layer and sponge layer are fixed by the adhesive in no. 2 strip shape convex and are bonded.

[0006] The principle of the above technical solution is that no. 1 fabric layer and sponge layer are fixed by the adhesive in no. 1 strip shape convex and are bonded, and no. 2 fabric layer and sponge layer are fixed by the adhesive in no. 2 strip shape convex and are bonded, no. 1 strip shape convex and no. 2 strip shape convex are intervally arranged correspondingly, so that the ventilation of no. 1 fabric layer, sponge layer and no. 2 fabric layer between adjacent no. 1 strip shape convex is not affected, and the ventilation is better, when making sofa surface fabric, people sit on no. 1 fabric layer, because the section of no. 1 strip shape convex is arc-shaped, and the adhesive in no. 1 strip shape convex is not easy to deform after solidification, so no. 1 strip shape convex will sink under pressure, and there will be a gap between the two sides of no. 1 strip shape convex and the human body, which is convenient for air circulation and good ventilation, and the adhesive is immersed in no. 1 strip shape convex and no. 2 strip shape convex, no. 1 fabric layer and sponge layer are fixed by the adhesive in no. 1 strip shape convex and are bonded, and no. 2 fabric layer and sponge layer are fixed by the adhesive in no. 2 strip shape convex and are bonded, so the adhesive strength is high, and the overall composite strength is guaranteed.

[0007] Preferably, the distance between adjacent first strip-shaped protrusions is 1 cm, and the width of the first strip-shaped protrusion is 0.3 cm, so as to ensure the overall composite strength and the overall air permeability.

[0008] Further, the first fabric layer is made of wear-resistant fabric to increase the wear resistance of the surface.

[0009] The air-permeable composite sofa fabric has the advantages that the first fabric layer and the sponge layer are fixed by the adhesive in the first strip-shaped protrusion, the second fabric layer and the sponge layer are fixed by the adhesive in the second strip-shaped protrusion, the adhesive strength is high, the overall composite strength is ensured, the first fabric layer, the sponge layer and the second fabric layer between adjacent first strip-shaped protrusions are not bonded together, the air permeability is good, and there is a gap between the two sides of the first strip-shaped protrusion and the human body during use, so that the air circulation is facilitated and the air permeability is good.

[0013] In order to further illustrate the technical means and effects adopted by the utility model to achieve the predetermined utility model purposes, the specific embodiments, structures, features and effects according to the utility model are described in detail as follows in combination with the drawings and preferred embodiments.

[0014] Embodiment 1:

[0015] As shown in Figure 1 , 2 , 3, the utility model discloses an air-permeable composite sofa fabric, including first fabric layer 1, second fabric layer 3, sponge layer 2, the upper end face of sponge layer 2 is spaced apart and is provided with the first strip-shaped protrusion 4 of arc cross section, the distance between adjacent first strip-shaped protrusions 4 is 1 cm, the width of first strip-shaped protrusion 4 is 0.3 cm, the position of the lower end face of sponge layer 2 corresponding first strip-shaped protrusion 4 is provided with the second strip-shaped protrusion 5 of arc cross section, the upside of sponge layer 2 is provided with first fabric layer 1, first fabric layer 1 uses wear-resistant fabric, the downside of sponge layer 2 is provided with second fabric layer 3, first strip-shaped protrusion 4, second strip-shaped protrusion 5 is soaked in adhesive, first fabric layer 1 and sponge layer 2 are fixed by the adhesive in first strip-shaped protrusion 4 and are bonded, second fabric layer 3 and sponge layer 2 are fixed by the adhesive in second strip-shaped protrusion 5 and are bonded.

[0016] The principle of the technical scheme is that the first fabric layer 1 and the sponge layer 2 are fixed by the adhesive in the first strip-shaped protrusion 4, the second fabric layer 3 and the sponge layer 2 are fixed by the adhesive in the second strip-shaped protrusion 5, and the first strip-shaped protrusion 4 and the second strip-shaped protrusion 5 are arranged in correspondence with intervals. Therefore, the air permeability of the first fabric layer 1, the sponge layer 2 and the second fabric layer 3 between adjacent first strip-shaped protrusions 4 is not affected, and the air permeability is good. When the sofa surface layer fabric is made, a person sits on the first fabric layer 1. Since the cross section of the first strip-shaped protrusion 4 is arc-shaped, and the adhesive in the first strip-shaped protrusion 4 is not easy to deform after solidification, the first strip-shaped protrusion 4 will sink under pressure, and there will be a gap between the two sides of the first strip-shaped protrusion 4 and the human body, which is convenient for air circulation and has good air permeability. Moreover, the adhesive is soaked in the first strip-shaped protrusion 4 and the second strip-shaped protrusion 5, the first fabric layer 1 and the sponge layer 2 are fixed by the adhesive in the first strip-shaped protrusion 4, the second fabric layer 3 and the sponge layer 2 are fixed by the adhesive in the second strip-shaped protrusion 5, the adhesive strength is high, and the overall high composite strength is ensured.
