Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

Please refer to FIG. 1, an embodiment provided by the present utility model: an elastic yarn, comprising a yarn core 1, a winding part 2 wound around the yarn core 1, and the winding part 2 is made of spandex and flax fibers twisted together. Flax fiber has a fast moisture absorption and dehumidification speed, which can adjust the ecological temperature environment of the human skin surface in time. When it comes into contact with the skin, it will produce pores, which can help the skin to perspire and clean the skin. Spandex has excellent elasticity and is more flexible. Resistant to chemical degradation, spandex has good acid and alkali resistance, sweat resistance, seawater resistance, dry cleaning resistance, and abrasion resistance, so that the entire yarn has good elasticity and abrasion resistance. A breathable layer 3 is arranged between the parts 2, the breathable layer 3 is a sleeve structure, and the breathable layer 3 is a mesh structure woven from polyamide fibers and seaweed fibers.
