Description

Technical Field

[0001] This utility model relates to the field of leather base fabric technology, specifically to a functional elastic leather base fabric. Background Technology

[0002] Currently, China's production capacity of artificial and synthetic leather accounts for more than 70% of the world's total output. With the continuous emergence of new technologies, the synthesis technology of artificial and synthetic leather is also constantly developing. Now, most artificial and synthetic leathers are composite materials made by coating or impregnation, using fiber-based fabric as reinforcement material and polymer resin as matrix. The performance and development of the base fabric determine the development of the artificial leather industry.

[0003] For some special applications, synthetic composite leather base fabric has greater advantages. Current leather furniture usually uses simple synthetic composite leather for covering. On the inside of the surface leather, there is also a cotton layer to enhance the elasticity and soft touch. However, the elasticity of the cotton layer is not particularly good. Moreover, the cotton fiber layer is prone to damage and deformation when it is damp or subjected to excessive pressure in a localized area, and it cannot rebound. Utility Model Content

[0004] In view of the prior art, the purpose of this utility model is to provide a functional furniture outer covering leather base fabric structure design with durable elasticity.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a functional elastic leather base fabric, comprising a base fabric, an elastic layer, and a surface base fabric, wherein a woven layer is provided between the base fabric, the elastic layer, and the surface base fabric; the elastic layer comprises a cavity layer and a cover layer; the cavity layer comprises a cavity and a support portion; the cover layer and the support portion are glued together to seal the opening of the cavity to form a sealed air cavity.

[0006] As a further feature of the above solution, the support portion is also provided with a grid groove, and the cover layer is provided with a mesh-like protrusion that matches the grid groove.

[0007] As a further feature of the above scheme, the woven layer includes two interlaced fabric strips with filling gaps between adjacent fabric strips.

[0008] As a further feature of the above scheme, the elastic layer is made of polyurethane material, and adhesive is brushed on both sides of the braided layer. The adhesive also flows relative to both sides of the braided layer through filling gaps.

[0009] Beneficial effects: The elastic leather base fabric of this utility model forms an elastic layer of air spring by composite in the inner layer. The inner layer of the leather base fabric has a continuous and stable rebound performance. A cross-shaped hollow woven layer is also set as an interlayer adhesive composite. The woven layer increases the composite strength. The air spring can maintain the elasticity of the fiber for a long time. After being covered on the outer surface of furniture, it provides a softer and more elastic touch. Attached Figure Description

[0015] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, where there is no conflict, the embodiments and features described in these embodiments can be combined with each other.

[0016] like Figure 1-4 The functional elastic leather base fabric shown includes a base fabric 1, an elastic layer 2, and a surface base fabric 4, with a woven layer 3 disposed between the base fabric 1, the elastic layer 2, and the surface base fabric 4. The elastic layer 2 includes a cavity layer 22 and a cover layer 21. The cavity layer 22 includes a cavity 23 and a support portion 24. The cover layer 21 and the support portion 24 are glued to seal the opening of the cavity 23 to form a sealed air cavity.

[0017] With the above-described structural design, the leather base fabric of this utility model is manufactured by applying adhesive to both sides of the woven layer 3 to bond the multiple layers together. For the elastic layer 2, which mainly constitutes the elasticity, adhesive is applied to the corresponding composite surfaces of the cover layer 21 and the cavity layer 22. Then, the two are bonded together and the adhesive is used to seal the cover layer 21 and the support part 24, so that the cavity 23 forms a sealed air cavity. Under external pressure, the air inside forms an air spring. The support part 24 maintains the shape of the elastic layer 2. Compared with ordinary elastic cotton, the thermal conductivity of polyurethane material itself is much lower than that of air, and it can also provide some heat preservation. Its aging resistance and other characteristics allow it to maintain stable and long-term rebound ability without damaging the seal.

[0018] As a further improvement to the above solution, the support portion 24 is also provided with a grid groove 25, and the cover layer 21 is provided with a mesh protrusion 26 that matches the grid groove 25. In this embodiment, the support portion 24 is provided with a grid groove 25 in both directions, and the cover layer 21 is provided with a mesh protrusion 26 for filling. Adhesive is also applied before filling, which can improve the sealing of the cover layer 21 and the cavity layer 22, allowing the bladder 23 to maintain airtightness independently, preventing the trapped air inside from flowing to each other, and improving the durability of use.

[0019] As a further feature of the above scheme, the braided layer 3 includes two interlaced fabric strips 31 with a filling gap 32 between adjacent fabric strips 31. The elastic layer 2 is made of polyurethane material. Adhesive is brushed on both sides of the braided layer 3. The adhesive also flows relative to both sides of the braided layer 3 through the filling gap 32. The filling gap 32 allows the adhesive brushed on both sides of the braided layer 3 to flow, thereby improving the composite strength between the upper and lower layers and the braided layer 3 during lamination.

[0020] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of this utility model and its equivalents, this utility model also intends to include these modifications and variations.
