Example one

The present embodiment will be described in detail with reference to fig. 1 to 3. The semi-elastic pongee fabric comprises a pongee fabric body 1 formed by interweaving warp yarns and weft yarns, and an e-PTFE waterproof breathable film 2 compounded on one side of the pongee fabric body 1. The warp yarns used by the kasugan fabric body are combined filament yarns, and the weft yarns used by the kasugan fabric body are DTY polyester filament yarns. The weft yarn of the semi-elastic shorea-made fabric is DTY polyester filament, so that the fabric has certain elasticity in the weft direction. The used e-PTFE waterproof breathable film 2 has good elasticity, and after being compounded with the Chunzi fabric body 1, the compound fabric still can have certain elasticity.

The combined filament yarn comprises polyester POY filament and polyester FDY filament, and the POY filament and the FDY filament are provided with bonding points formed by ultrasonic waves. The specification of the selected POY filament is 100-150D/36-144F, and the specification of the selected FDY filament is 100-150D/48-96F; both the POY filaments and the FDY filaments selected were untwisted. The preparation process of the POY and FDY combined filament yarn comprises the following steps: (1) raw material selection, (2) preparation of a cabling ply, (3) air deformation, (4) double twisting, (5) twisting and shaping, and (6) plying.

Further, the used DTY polyester filament is 100D/36F, and the used raw material is modified PET. The molecular chain of the modified PET consists of a PTA chain segment, an EG chain segment, a SIPA chain segment and a pentanediol chain segment, and titanium dioxide is dispersed among the molecular chains of the modified PET; because the PET contains titanium dioxide which is a flatting agent, the polyester fiber has similar luster with cotton fiber; because the molecular chain of the PET contains SIPA chain segment and pentanediol chain segment, the moisture absorption performance of the polyester fiber is similar to that of cotton fiber; therefore, the polyester fiber has good cotton-like effect.

Further, the cross section of at least one monofilament in the selected polyester FDY filaments comprises a single fiber 21 with a circular cross section and a protrusion 22 arranged on the outer peripheral surface of the single fiber 21. The polyester yarn with the special-shaped cross section can enable light rays to be reflected unevenly on the surface of the yarn, so that the silk-like fabric prepared from the silk-like spandex core-spun yarn has soft hand feeling and luster close to that of silk. And the monofilament forming the terylene FDY fully drawn yarn has a hollow structure, so that the terylene FDY fully drawn yarn has a certain warm-keeping function, and the defect that the imitated silk fabric is not warm-keeping can be overcome.

Further, the cross section of at least one monofilament in the selected DTY polyester yarns is of a three-leaf special shape and comprises a leaf I23, a leaf II 24 and a leaf III 25; the length ratio of the leaf I23 to the leaf II 24 to the leaf III 25 is 1.0:1.1:2.5, the width ratio of the leaf I23 to the leaf II is 1:1.8:1, the length to the width ratio of the leaf I23 is 3.5:1, and the included angle of the center lines of two adjacent leaves is 120 degrees. So that the light rays are irregularly refracted on the surface of the yarn, and the yarn has luster similar to that of real silk.

This embodiment will be described in detail with reference to fig. 4. The difference between the semi-elastic pongee related in the embodiment and the embodiment one is that: an antibacterial coating 3 is arranged between the pongee fabric body 1 and the e-PTFE waterproof breathable film 2.

The foregoing detailed description of the preferred embodiments of the utility model has been presented. It should be understood that numerous modifications and variations could be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts. Therefore, the technical solutions available to those skilled in the art through logic analysis, reasoning and limited experiments based on the prior art according to the concept of the present invention should be within the scope of protection defined by the claims.
