[0018] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] Combination Figure 1 and Figure 2 , this embodiment is described in detail. The present invention relates to a method for preparing a fabric for a fiber micromechanical bonding fastener, wherein the single-sided adhesive webbing comprises a base fabric 1 and a fluff layer 2 fixedly arranged on one side of the base fabric 1, and the ends of the fluff fibers in the fluff layer 2 have protruding ends 3 formed by melting and solidification; the edge position of the protruding ends 3 protrudes from the fluff fibers. The fluff fibers used are hot-melt synthetic fibers, and the protruding ends 3 are formed by the hot-melt fibers being melted and solidified after being irradiated by a laser beam. When the single-sided adhesive webbing is used, when the adhesive webbing has one side of the fluff layer in contact, the presence of the protruding ends 3 will increase the bonding force between the webbings.

[0020] The preparation method comprises the following steps:

[0021] S1. Weaving of grey cloth: The grey cloth is woven by a weaving device; the grey cloth comprises an upper grey cloth 11 and a lower grey cloth 12, and a connecting pile warp 13 for connecting the upper grey cloth 11 and the lower grey cloth 12; the connecting pile warp 13 is a hot-melt synthetic fiber filament. The weaving device used in this embodiment is a weaving machine, and the weaving is performed according to the double-layer fabric.

[0022] Further, the heat-fusible synthetic fiber filaments are polyamide filaments, polyester filaments, polypropylene filaments, polyethylene filaments or polylactic acid filaments. In this embodiment, polyamide filaments are selected, specifically nylon 6 fiber filaments.

[0023] S2. Laser cutting: A laser emitting device 14 is provided on the weaving equipment to melt and cut the connecting pile warps to form a single-sided adhesive webbing. When the laser beam is irradiated onto the connecting pile warps, the connecting pile warps can be cut at the irradiated position, and the connecting pile warps are heated, which causes the connecting pile warps at the cut position to melt, and after melting, pile fibers are formed, thereby forming a pile layer 2. The ends of the upper grey cloth 11 and the lower grey cloth 12 are formed, and after melting, the ends of the pile fibers flow, thereby forming a protruding end 3, thereby changing the end morphology of the pile fibers. Figure 4 As shown, in the prior art, a velvet cutting knife 15 is used to move in the width direction to cut the connecting velvet warps 13. The power of the laser emitting device 14 can be adjusted according to the different materials of the hot-melt synthetic fiber filaments used.

[0024] Furthermore, the laser emitting device 14 moves linearly along the width direction of the ribbon. During the movement, the laser emitting device 14 can cut off the connecting pile warp 13 to form two pieces of fabric, which are then rolled up separately.

[0025] Furthermore, the laser emitting device 14 can also be fixed on a swing device and swing within the width of the ribbon. The laser emitting device 14 swings left and right to cut the connected fleece warp to form two pieces of fabric, and then reel them up separately.

[0026] Furthermore, the base fabric 1 is an elastic webbing, but it can also be an inelastic webbing. Whether the base fabric 1 is elastic depends on the raw materials used for the upper grey fabric 11 and the lower grey fabric 12. The upper grey fabric 11 is interwoven with the upper warp yarn and the upper weft yarn, and the connecting velvet warp 13 in the upper grey fabric is V-shaped or W-shaped consolidation of the upper weft yarn. The lower grey fabric 12 is interwoven with the lower warp yarn and the lower weft yarn, and the connecting velvet warp 13 in the lower grey fabric is V-shaped or W-shaped consolidation of the lower weft yarn.

[0027] When the upper warp yarn and the lower warp yarn can be selected as elastic core-spun yarn, the prepared upper grey cloth and the lower grey cloth have warp elasticity.

[0028] The preferred specific embodiments of the present invention are described in detail above. It should be understood that a person skilled in the art can make many modifications and changes based on the concept of the present invention without creative work. Therefore, any technical solution that can be obtained by a person skilled in the art through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of the prior art should be within the scope of protection determined by the claims.
