The utility model is further configured to: the core layer is formed by twisting a plurality of fibers with special-shaped cross sections, and the fibers with special-shaped cross sections are made of terylene.

Through adopting above-mentioned technical scheme, form the sandwich layer by a plurality of dysmorphism cross-section fibre twists, dysmorphism cross-section fibre has fine fluffiness, and dysmorphism cross-section fibre is made by the dacron, has strengthened the elastic effect of sandwich layer to guarantee holistic structural strength.

The utility model is further configured to: the cross section of the profiled cross section fiber is of a five-leaf type.

By adopting the technical scheme, the cross section of the fiber with the special-shaped cross section is set to be a five-leaf type, the special-shaped degree is high, the cohesive force of the twisted fiber with the special-shaped cross section is increased, the strength of the whole structure is enhanced, and the anti-wrinkle effect is achieved.

The utility model is further configured to: the number of the special-shaped cross section fibers is three, and a triangular structure is formed.

Through adopting above-mentioned technical scheme, the triangle-shaped structure is comparatively stable, has guaranteed the intensity of whole sandwich layer.

In conclusion, the utility model has the following beneficial effects:

the coating includes the anti-wrinkle yarn of inseparable winding in the sandwich layer outside, first compound yarn includes the yarn core and dissolves portion and winding part around the inseparable winding alkali of yarn core, soak first compound yarn in alkaline solution, the alkali that dissolves the portion on the first compound yarn is met alkali and is dissolved, only leave the winding part, the winding part is spiral winding around the yarn core, first compound yarn twisting after will a plurality of alkali washes again forms anti-wrinkle yarn, a plurality of first compound yarn twisting backs, the winding part on every first compound yarn laminates each other, contact area has been increased, thereby the cohesive force of first compound yarn has been increased, thereby play and prevent the balling-up, the effect of fluff, thereby make the sewing thread wear the needle more easily.
