In the figure: 1. an inner layer; 2. a middle layer; 3. an outer layer; 4. and (3) an adhesive.

Detailed Description

The utility model is further described with reference to the following figures and specific examples.

As shown in fig. 1, an antibacterial polyester filament sofa leather base fabric is characterized by comprising: an inner layer 1, a middle layer 2 and an outer layer 3;

the inner layer 1 is a soft elastic layer, the soft elastic layer is formed by blending and weaving four fabric fibers including novel nylon bi-component fibers, novel superfine denier fibers, cotton satin fibers and plush fibers, and the woven fabric has the characteristics of soft texture, high elasticity, moisture absorption, air permeability, thickness, wear resistance, stiffness, no wrinkle and the like. The inner layer 1 is the bottom layer of the sofa leather base cloth, the upper part of the inner layer is sequentially provided with a middle layer 2 and an outer layer 3, and the outer layer 3 is provided with a leather surface. The inner layer 1 mainly has the functions of improving the structural strength and elasticity of the sofa leather base cloth and improving the softness and comfort degree of the sofa leather base cloth to a certain extent.

The middle layer 2 is an antibacterial polyester layer, the antibacterial polyester layer is formed by interweaving warp yarns and weft yarns, the warp yarns are antibacterial polyester filaments, the weft yarns comprise first weft yarns and second weft yarns, the first weft yarns are antibacterial polyester filaments, and the second weft yarns are flame-retardant polyester filaments; the first weft yarns and the second weft yarns are mutually doubled wefts, and the warp yarns, the first weft yarns and the second weft yarns are interwoven in a sinking and floating manner to form a weft duplex structure; preferably, the weft double-weave surface layer is formed by weaving four warp yarns and four first weft yarns in a right oblique manner; the weft double-weave inner layer is formed by weaving warp yarns and second weft yarns in a left oblique crossing mode through four wefts; the arrangement ratio of the first weft yarns to the second weft yarns is 1: 1.
