Abstract
The invention relates to a novel seamless waterproof zipper, which comprises a zipper belt and zipper teeth. The zipper is zipped so that the zipper teeth are meshed with each other; the zipper is stretched transversely to eliminate the buffering distance between the zipper teeth; thermoplastic polyurethane (TPU) granules are melted into liquid state which is pressurized and extruded to be coated on the back of the zipper, including the zipper belt and the zipper teeth, and is infiltrated sufficiently; and the zipper is cooled by water, and a TPU layer on the back of the zipper is divided along the midline so that the seamless water zipper is produced.
Description
Technical field
The present invention relates to the slide fastener technical field, a kind of specifically waterproof slide fastener.
Background technology
Normally used waterproof slide fastener substantially all is the chain belt that adopts waterproof material to make, and by the fixing chain belt of sprocket, plays waterproof effect.Now the zipper strip waterproof material that uses on the market is very expensive, and many environment is polluted.Also have a kind of method to utilize waterproof membrane exactly, be pasted on the chain belt, but this product just is very easy to come off through washing back waterproof membrane.And owing to have certain buffer distance after the sprocket engagement, after slide fastener laterally bore certain pulling force, the slit can appear in the engaging piece of sprocket, caused water resistance to reduce greatly.Product of the present invention is the improvement of carrying out on this basis, makes waterproof slide fastener become big at tension force, under the condition that latter's intensity stretches, and waterproof more.
Summary of the invention
Purpose of the present invention is for providing a kind of water resistance high novel seamless waterproof zipper.
The technical scheme that realizes the foregoing invention purpose is as follows:
A kind of novel seamless waterproof zipper comprises chain belt and sprocket, and slide fastener is pulled on, and makes the sprocket engagement; With the slide fastener cross directional stretch, eliminate the buffer distance between the sprocket; To become liquid state after TPU (thermoplastic polyurethane) particles fuse, the pressurization squeezing and coating comprise chain belt and sprocket at the slide fastener back side, and it is fully permeated; With the slide fastener water cooling, the TPU layer at the slide fastener back side is scratched along center line, seamless waterproof zipper.
The present invention is by eliminating the buffering distance between the sprocket, make slide fastener when being subjected to lateral pull, the slit can not occur, adopt TPU one deck waterproof membrane of filming at the slide fastener back side simultaneously, because TPU can fully penetrate in the slit of chain belt inside and sprocket, so be not easy to come off, integral waterproofing effect of the present invention improves greatly, and durable wearability improves long service life.
Description of drawings
Fig. 1 is the sprocket portion structure chart of existing slide fastener
Fig. 2 is the structure chart of the sprocket portion of slide fastener of the present invention
Fig. 3 is a structural representation of the present invention
L length is the buffer distance of sprocket among the figure; R is the length of sprocket barb.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing, specific embodiment and Comparative Examples.
As shown in Figure 1, the length of the barb of the sprocket of existing slide fastener is R, when sprocket meshes, have certain buffer distance L between the barb of both sides sprocket, when slide fastener was subjected to lateral pull, buffer distance shortened, make between sprocket and the chain belt slit to occur, the water resistance of slide fastener is destroyed.
As shown in Figure 2, novel seamless waterproof zipper of the present invention comprises chain belt 3 and sprocket 2 and pull head 1, and slide fastener is pulled on, and makes sprocket 2 engagements; With the slide fastener cross directional stretch, eliminate the buffer distance between the sprocket; With becoming liquid state after TPU (thermoplastic polyurethane) particles fuse, be coated in the slide fastener back side, comprise chain belt and sprocket, it is fully permeated form thermoplastic polyurethane layer 4; With the slide fastener water cooling, the TPU layer 4 at the slide fastener back side is scratched along center line, seamless waterproof zipper.
