[0002] With the improvement of living standards and the progress of society, people's requirements for fabrics are getting higher and higher. Textiles made of highly elastic filaments or fiber yarns such as spandex, Sorona fiber yarn, PA66, etc. have good elasticity. Elastic fabrics are very popular because of their comfort. Suede fabrics can be used to replace natural leather because of their good imitation leather effect, and are also widely used in the fields of clothing and household goods. Today's suede fabrics with four-sided elasticity usually use spandex filaments as the core yarn, but if the spandex filaments break during use, the elasticity of the suede fabric will decrease. How to prepare a spandex four-sided elastic suede fabric to reduce the impact of spandex breakage has become a problem to be solved. Utility Model Content

[0017] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] Embodiment 1

[0019] Combination Figure 1 The present embodiment is described in detail. The present embodiment involves a spandex four-way stretch suede fabric, comprising a composite surface elastic suede fabric 1, a four-way stretch fabric base layer 2 and an inner elastic antibacterial fabric layer 3.

[0020] The surface elastic suede fabric 1 is formed by interweaving the first elastic core-spun yarn as warp yarn and weft yarn, wherein the first elastic core-spun yarn includes a first core yarn and a first wrapping yarn wrapped around the outside of the core yarn; the first core yarn is a strand formed by twisting spandex filament and Sorona fiber yarn, and the wrapping yarn is PTT polyester filament.
