Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples.

Example (b):

this waterproof cold-proof dacron, as shown in fig. 1 and 2, including surface course 1 and fixed connection at the waterproof membrane 2 of its top surface, waterproof membrane 2 adopts the pu material, and the top surface of waterproof membrane 2 is provided with a plurality of thin fine hair 3, and the specific heat capacity of thin fine hair 3 is 20 times of the specific heat capacity of waterproof membrane 2 at least, and thin fine hair 3 constitutes through a plurality of dacron short fibers that bond at the 2 top surfaces of waterproof membrane.

The surface layer 1 is formed by warp and weft weaving of a contact yarn I and a contact yarn II, and the surface layer 1 is in a satin weave structure.

As shown in fig. 3, the first contact yarn comprises a first core layer 4, and a silver fiber 7 and a nylon fiber 8 spirally wound on the outer side of the first core layer in the same direction, wherein the thickness of the silver fiber 7 is smaller than that of the nylon fiber 8, the first core layer 4 is formed by twisting a first polyester fiber 5 and a first spandex fiber 6, and the first contact yarn further comprises a second polyester fiber 9 wound on the outermost side.

As shown in fig. 4, the second contact yarn includes a second core layer 10, and a chitin fiber 13, a cotton fiber 14 and an acrylic fiber 15 spirally wound on the outer side of the second contact yarn in the same direction, and an outer covering yarn 16 is wound on the outermost side of the second contact yarn, the second core layer 10 is formed by twisting two second spandex fibers 11, the outer covering coating 12 is coated on the outer side of the second spandex fibers 11, the outer covering coating 12 is made of a rubber material, and the outer covering yarn 16 is formed by false twisting a plurality of superfine polyester fibers 17.

When preparing the terylene cloth, firstly, a surface layer 1 is obtained, and the surface layer 1 is obtained by spraying and weaving a contact yarn I and a contact yarn II by a spraying weaving machine according to a weaving mode of a satin weave.

And contact yarn is first when production, twist earlier polyester fiber 5 and spandex fibre 6 and obtain sandwich layer 4, then with silver-colored fibre 7 and nylon fiber 8 syntropy spiral winding in the outside of sandwich layer 4, and because silver-colored fibre 7's thickness is less than nylon fiber 8's thickness, thereby make through two 9 reverse windings of polyester fiber when the outside forms contact yarn one, can make one of contact yarn forms a plurality of narrow and small spaces in, silver-colored fibre 7's setting makes one of contact yarn be difficult for appearing the condition that bacterial growing simultaneously, and nylon fiber 8 makes the cold-proof effect that makes contact yarn one obtain promoting.

When producing the second contact yarn, firstly coating the outer sides of two spandex fibers 11 with the rubber outer coating 12, then feeding the two spandex fibers 11 coated with the rubber outer coating 12 into a twisting machine to twist, enabling the core layer two 10 to twist and effectively increasing the elastic stiffness of the two spandex fibers, after obtaining the core layer two 10, then spirally winding the chitin fibers 13, the cotton fibers 14 and the acrylic fibers 15 on the outer sides in the same direction through a spindle spinner, enabling the second contact yarn to have an antibacterial and bacteriostatic effect through the chitin fibers 13, ensuring the heat preservation effect of the second contact yarn through the cotton fibers 14 and the acrylic fibers 15, finally carrying out air spinning on a plurality of superfine polyester fibers 17 through an air spinning machine to obtain the second outer coating yarn 16, winding the outer coating yarn 16 on the outermost side through a twisting machine to obtain the second contact yarn, and keeping the outer coating yarn 16 in a fluffy state, the second contact yarn has better warm-keeping effect.

After the waterproof membrane 2 is bonded on the top surface of the surface layer 1, the adhesive layer is coated on the top surface of the waterproof membrane 2, and then the polyester staple fibers are sprayed, so that the thin velvet 3 is formed on the top surface of the waterproof membrane 2, and then people can not feel cool when touching.
