Snap-in braid and preparation method thereof

Abstract

The invention discloses a snap-in braid and a preparation method thereof, relating to a braid preparation technology. The snap-in braid comprises a band and a bottom band, a plurality of circular holes are formed in the band through laser perforation, a shading reinforcing structure and a mushroom head are formed on the bottom band in a PU injection molding mode at a time. A reflective film is hot-pressed on the band; a plurality of hasp holes are formed in the reflective film through laser perforation and are arranged corresponding to the circular holes. According to the invention, injectionmolding is carried out through a PU (polyurethane) material, the mushroom head is formed at one time, the mushroom head has the characteristics of thickness, wear resistance, lightness and toughness,the service life of the snap-in braid is prolonged, and the circular holes corresponding to the mushroom head are formed in the surface of the braid through laser, so that the mushroom head and the braid can be accurately paired and more firmly snap-in. The laser through holes enable the reflective film to form a thermoplastic protective layer after hot melting and cooling, the surfaces of the circular holes can be protected against fuzzing, the bottom band is woven with the thermofuses, the laser through holes enable the inner walls of the circular holes to form a thermosetting protective layer, the inner walls of the circular holes are protected against fuzzing, and it is guaranteed that the hook-and-loop fastener performance of the braid is stable for a long time.

Description

technical field [0001] The invention relates to the technical field of webbing preparation, in particular to a buckle type webbing and a preparation method thereof. Background technique [0002] One of the accessories used in traditional luggage and shoe materials is straps, which have the function of tightening and restraining. Most of these accessories are made of Velcro, with rough surfaces and hook surfaces. This type of material is wear-resistant and The service life is not so ideal. After a long time of use, the rough surface will fluff, and the hooks on the hook surface will gradually wear off and fall off, which will reduce the adhesive performance of the accessories and affect the user experience. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a buckle webbing so as to improve user performance and experience. [0004] Technical solution: In order to achieve the ab...
