Detailed Description
The utility model is further described with reference to the following figures and specific examples.
Example one
The present embodiment will be described in detail with reference to fig. 1 to 4. The antistatic polyester fabric comprises a fabric base layer 1, wherein a polylactic acid nanofiber layer 2 and a waterproof breathable layer 3 are compounded on two sides of the fabric base layer 1 respectively. The polylactic acid nanofiber layer 2 is made of polylactic acid, and the polylactic acid has a good antibacterial effect and can avoid bacterial breeding.
In the embodiment, the fabric base layer 1 is formed by interweaving warp yarns and weft yarns, wherein the warp yarns comprise polyester filaments with antistatic polyester modifiers attached to the surfaces, and the weft yarns are antistatic low-shrinkage polyester fibers.
Antistatic low shrinkage polyester fiber includes the interior silk of outer silk 11 and the carbon fiber material of dacron material, and the interior silk is formed by behind 15-30 carbon fiber 12 twists, and interior silk twist 120 supplyes 170T/m, and outer silk 11 spiral wraps in the outside of interior silk, and the inside cavity of outer silk 11 is equipped with a plurality of beads 13 on the global of outer silk 1.
And wrapping the outer yarn made of the polyester material on the inner yarn formed by the carbon fiber yarn so as to obtain the antistatic low-shrinkage polyester fiber. The carbon fiber yarn has good conductivity, so that static electricity is not easy to generate in the polyester fiber, and the fabric manufactured by the utility model is not easy to generate static electricity and is not easy to cause secondary fire due to the static electricity; the carbon fiber has large elastic modulus and is not easy to shrink when being heated, so that the polyester fiber is not easy to shrink when being heated, and the practical fabric is not easy to shrink and deform when being heated.
