Embodiment 1

[0024] Step 1: Reasonably design the structure of the hook and loop fastener. The arrangement of the warp yarns in the fabric is 2 nylon multifilament warp yarns: 1 nylon hot-melt yarn monofilament warp yarn: 1 nylon monofilament hook yarn: 1 nylon hot-melt yarn single Silk warp yarns are arranged in such a cycle; the weft yarns in the fabric are arranged in the following way: 3 nylon multifilament weft yarns: 1 nylon hot-melt filament monofilament weft yarn, so circularly arranged.

[0025] Step 2: Optimize the raw material parameters of the hook and loop fastener. The linear density of the nylon multifilament warp yarn is 200D, the diameter of the nylon monofilament hook yarn is 0.15mm, the linear density of the nylon hot-melt monofilament is 50D, and the melting temperature is 70°C. The linear density of the multifilament weft yarn is 250D.

[0026] Step 3: Three pan heads are required for warping, one pan head for nylon hot-melt monofilament, one pan head for nylon monofil...

[0030] Step 1: Reasonably design the structure of the hook and loop fastener. The arrangement of the warp yarns in the fabric is 2 nylon multifilament warp yarns: 1 nylon hot-melt yarn monofilament warp yarn: 1 nylon monofilament hook yarn: 1 nylon hot-melt yarn single Silk warp yarns are arranged in such a cycle; the weft yarns in the fabric are arranged in the following way: 3 nylon multifilament weft yarns: 1 nylon hot-melt filament monofilament weft yarn, so circularly arranged.

[0031] Step 2: Optimizing the raw material parameters of the hook and loop, the linear density of nylon multifilament warp yarn is 230D, the diameter of nylon monofilament hook yarn is 0.20mm, the linear density of nylon hot-melt monofilament is 75D, and the linear density of nylon multifilament weft yarn for 280D.

[0036] Step 1: Reasonably design the structure of the hook and loop fastener. The arrangement of the warp yarns in the fabric is 2 nylon multifilament warp yarns: 1 nylon hot-melt yarn monofilament warp yarn: 1 nylon monofilament hook yarn: 1 nylon hot-melt yarn single Silk warp yarns are arranged in such a cycle; the weft yarns in the fabric are arranged in the following way: 3 nylon multifilament weft yarns: 1 nylon hot-melt filament monofilament weft yarn, so circularly arranged.

[0037] Step 2: Optimize the raw material parameters of the hook and loop fastener. The linear density of the nylon multifilament warp yarn is 260D, the diameter of the nylon monofilament hook yarn is 0.30mm, the linear density of the nylon hot-melt monofilament is 100D, and the linear density of the nylon multifilament weft yarn It is 300D.

Abstract

The present invention is applicable to the textile field, and provides a hot-melt non-adhesive nylon Velcro and its manufacturing method. Melt at a high temperature and make the adjacent nylon filaments bond together. By adopting this structure of the hook and loop fastener, it can not only achieve the purpose of no burr when cutting, and no loosening during use, but also does not need to coat the bottom of the hook and loop fastener Polyurethane resin glue technology avoids the harm of environmental pollution caused by the volatilization of organic solvents into the air during drying, and realizes that the hook and loop fastener is breathable and thin, and there is no problem of hydrolysis of the glue when used in water.

Description

technical field [0001] The invention belongs to the field of textiles, and in particular relates to a hot-melt non-adhesive nylon hook and loop and a manufacturing method thereof. Background technique [0002] The hook and loop fasteners circulating in the domestic and foreign markets all need to coat the bottom of the hook and loop with polyurethane resin glue, so that the structure of the hook and loop can be consolidated into one, so that there is no burr when cutting, and it will not fall apart during use, but polyurethane Resin glue should be diluted with organic solvent, and it will volatilize into the air during drying, which will cause certain environmental pollution hazards. Contents of the invention [0003] The object of the present invention is to provide a hot-melt non-adhesive nylon Velcro, which aims to solve the problem that the existing Velcro needs to be coated with polyurethane resin glue on the bottom, which is easy to pollute the environment. [0004]...
