[0019] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0020] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.

[0021] This embodiment relates to a down-proof fabric. Figure 1, comprising: a face cloth 100, a base cloth 200, and a bonding portion 300 bonded between the face cloth 100 and the base cloth 200, wherein the bonding portion 300 is in a long strip shape, and both ends are arranged in an arc shape. In this embodiment, the bonding portion 300 is used to bond the face cloth 100 and the base cloth 200 together, and the bonding portion 300 is arranged in a long strip shape to increase the bonding area between the face cloth 100 and the base cloth 200, so that the face cloth 100 and the base cloth 200 are better bonded together. Compared with the existing rectangular gluing edges at both ends of the adhesion part 300, the gluing edges at both ends of the adhesion part 300 in this embodiment are arc-shaped, so that when the surface cloth 100 and the base cloth 200 are peeled off, the pulling force can be evenly shared by the arc edges, thereby enhancing the bonding strength between the surface cloth 100 and the base cloth 200, making the two more effectively bonded, and avoiding the occurrence of cracks at the bonding point between the adhesion part 300 and the surface cloth 100 or the base cloth 200 during subsequent filling and use by consumers.

[0022] Further, refer to Figure 1-Figure 2 The adhesive part 300 is provided with a groove 310, which passes through the upper edge and the lower edge of the adhesive part 300. Since the surface cloth 100 and the base cloth 200 are made of different materials, their shrinkage is inconsistent after being subjected to high temperature. If the adhesive part 300 is set to be fully bonded, bubbles may be generated at the bonding point between the adhesive part 300 and the surface cloth 100 or the base cloth 200 during the bonding process of the surface cloth 100 and the base cloth 200, affecting the bonding strength between the adhesive part 300 and the fabric, thereby affecting the bonding strength between the surface cloth 100 and the base cloth 200. A groove 310 is provided on the adhesive portion 300, which helps to avoid the generation of bubbles at the joint between the adhesive portion 300 and the surface cloth 100 or the base cloth 200. The groove 310 passes through the upper and lower edges of the adhesive portion 300, which helps to increase the discharge of bubbles during gluing, reduce empty bags, and improve the bonding strength between the adhesive portion 300 and the surface cloth 100 or the base cloth 200, thereby improving the bonding strength between the surface cloth 100 and the base cloth 200.

[0023] Furthermore, a plurality of grooves 310 are provided to quickly discharge bubbles generated during the glue pressing. Figure 2 , multiple grooves 310 are arranged in parallel. Specifically, multiple grooves 310 are parallel and evenly distributed on the bonding portion 300. Compared with the design of a single groove 310 or a non-parallel groove 310, multiple parallel grooves 310 can cover a wider glue pressing area, thereby ensuring that bubbles can be effectively and quickly removed on the entire glue pressing bonding interface.

[0024] In this embodiment, refer to Figure 2The groove 310 is arranged obliquely to increase the discharge area of ​​bubbles during glue pressing and speed up the bubble discharge speed. At the same time, the oblique groove 310 design allows bubbles to be discharged smoothly along the oblique direction of the groove 310 during the glue pressing process, avoiding the obstruction and accumulation of bubbles in the horizontal groove 310. On the other hand, the oblique arrangement of the groove 310 also prevents glue from seeping into the base fabric 200. In some embodiments, the groove 310 can also be arranged longitudinally.

[0025] Further, refer to Figure 2 The inclination angle of the groove 310 is 30°-60°, the air bubble discharge path is smoother, and the retention time of the air bubble in the glue pressing process is reduced, thereby improving the air bubble discharge efficiency. In other embodiments, the inclination angle of the groove 310 can also be set to other angle ranges.

[0026] In this embodiment, the radial peeling strength between the face fabric 100 and the base fabric 200 is greater than 10 N, and the weft peeling strength is greater than 7 N. In this embodiment, by improving the design of the adhesive portion 300, the radial peeling strength and the weft peeling strength between the face fabric 100 and the base fabric 200 are greater, so that the face fabric 100 and the base fabric 200 maintain good adhesion, and the face fabric 100 and the base fabric 200 are more effectively adhered.

[0027] In this embodiment, one of the surface fabric 100 and the base fabric 200 is a composite fabric, and the other is a calendered fabric. The composite fabric is made of polyester matte high elastic yarn composite TPU hot melt film; the calendered fabric is made of polyester semi-gloss yarn and semi-gloss T800 yarn through calendering. The anti-velvet fabric in this embodiment uses the composite fabric and the calendered fabric, which has a good three-dimensional sense, certain elasticity and good air permeability. The composite material and calendered material mentioned in this embodiment are both commercially available fabrics, and the manufacturing process of the fabrics used is also existing technology.

[0028] In this embodiment, refer to Figure 1 There are multiple bonding parts 300, which are evenly distributed and bonded between the surface cloth 100 and the base cloth 200, so as to facilitate the subsequent filling work and the anti-down effect of the bonding parts 300 bonding the surface cloth 100 and the base cloth 200 after the filling, while ensuring the beauty of the fabric surface and the down, duck down and other warm materials are evenly filled between the base cloth 200 and the surface cloth 100 during the filling process.

[0029] In this embodiment, the glue is heated and rolled on the pattern roller through the existing glue pressing process. The pattern roller is provided with a diagonal raised portion having the same structure as the adhesion portion 300. The glue is applied on the diagonal raised portion. There are multiple diagonal raised portions, which are evenly distributed on the surface of the pattern roller. The diagonal raised portion is provided with multiple diagonal raised portions, and the diagonal grooves between the diagonal raised portions correspond to the grooves 310 of the adhesion portion 300.

[0030] After the base fabric 200 contacts the pattern roller and is coated with glue, the base fabric 200 is compounded with the surface fabric 100 to maintain a certain tension and pressure so that they are bonded together. Wherein, the pattern roller is an existing product.

[0031] In this embodiment, the material of the adhesive portion 300 is commercially available PUR glue with stronger adhesion.

[0032] Further, a filler is provided between the surface fabric 100 and the base fabric 200. In this embodiment, the filler is down. In some embodiments, the filler can also be warming materials such as duck down and goose down.

[0033] The advantages of the utility model are: the bonding part 300 bonded between the surface cloth 100 and the base cloth 200 is in the shape of a long strip and the two ends are in an arc shape. The long strip shape increases the bonding area between the surface cloth 100 and the base cloth 200, so that the surface cloth 100 and the base cloth 200 are better fitted together; and the two ends are in an arc shape so that when the surface cloth 100 and the base cloth 200 are peeled off, the tension can be evenly shared by the arc edge, thereby enhancing the bonding strength between the surface cloth 100 and the base cloth 200, so that the two can be more effectively bonded. The oblique groove 310 in the bonding part 300 is designed to increase the removal of bubbles during gluing, reduce empty bags, and further improve the bonding strength between the surface cloth 100 and the base cloth 200.

[0034] The above is only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
