Problems solved by technology

Since the water-repellent zipper is coated or the waterproof film is attached to the surface of the zipper tape under a certain temperature and pressure through the adhesive, the operation is troublesome and the softness of the tape is destroyed. At the same time, the coated zipper tape The thickness has increased, which affects the smoothness of the zipper; the water-repellent zipper realized by soaking or spraying chemical liquid, after a period of use, the surface chemical agent will become invalid, thus losing the water-repellent function

Embodiment 1

[0060] Use polyamide hot-melt adhesive with a melting point of 95°C on the market, heat it in a metal container until the hot-melt adhesive completely melts and becomes liquid, disperse and soak conventional 300D polyester filaments into the hot-melt adhesive solution, take it out, and let it dry naturally About 30 seconds, when the surface of the yarn is slightly solidified, the obtained adhesive layer yarn is coiled into rolls for use.

[0061]Use the above-mentioned adhesive layer yarns as warp and weft threads to weave zipper tapes, sew the teeth to form zipper codes; steam iron the zipper codes, the pressure of steam ironing is 0.4MPa ~ 0.5MPa, and the surface temperature is 100 At ~130°C, the No. 7 water-repellent zipper is obtained by cutting and assembling the slider in the rear channel.

[0062] According to the above test method, test the water-repellent performance and smoothness of the water-repellent zipper. The test results are: the anti-splashing water reaches ...

Embodiment 2

[0064] Use 150D polyester hot-melt yarn with a melting point of 95°C on the market, mix it with regular 300D polyester yarn as weft, and weave it with the warp of regular 300D polyester yarn to form a zipper tape. The hot-melt yarn is fully in contact with the warp and weft, Teeth form the zip closure. Put the zipper into a steam ironing belt, the pressure of steam ironing is 0.4MPa-0.5MPa, the surface temperature is about 100-130℃, and the slider is cut and assembled in the rear channel to make the No. 7 water-repellent zipper.

[0065] According to the above test method, test the water-repellent performance and smoothness of the water-repellent zipper. The test results are: the water repellency reaches level 4, and the smoothness is lower than 6N.

[0066] It can be seen from the above examples that the present invention provides a water-repellent cloth tape, which is prepared by the following method: weaving the yarn containing hot melt adhesive, molding it with ironing ta...

Abstract

The invention provides a water-repellent cloth tape and a water-repellent zipper. The water-repellent cloth tape is prepared by the following method: weaving yarns containing hot melt adhesive, molding the tape to obtain cloth tape; The yarn is made by the following method: attaching hot melt adhesive to the surface of a single-ply polyester yarn to obtain a yarn containing hot melt adhesive; the material of the hot melt adhesive is selected from polyamide and / or polyester; or the said hot melt adhesive contains The hot-melt adhesive yarn is produced by the following method: polyester yarn and hot-melt yarn are intermixed, and the yarn containing hot-melt adhesive is obtained by weaving; the material of the hot-melt yarn is selected from polyamide and / or polyester. The zipper made of the water-repellent cloth tape provided by the invention has relatively excellent water-repellent performance. It also has excellent smoothness. The water-repellent grade of the water-repellent zipper reaches 4~5, and the smoothness is lower than 6N.

Description

technical field [0001] The invention relates to the technical field of zippers, in particular to a water-repellent cloth tape and a water-repellent zipper. Background technique [0002] Due to the development needs of outdoor sporting goods, products with special functions such as water-repellent are more and more widely used, and zippers, as clothing accessories, also need to meet their special requirements in special clothing and other products. Then it is required that the whole can be water-repellent, especially the cloth belt part. [0003] At present, the methods of water-repellent cloth tapes include: first, use a waterproof coating or waterproof film to attach the surface of the zipper tape under a certain temperature and pressure through adhesive, so that the surface has the function of water-repellent; second, After soaking or spraying with chemical potion, it has the function of water repelling. Since the water-repellent zipper is coated or the waterproof film i...
