Referring to Fig. 5, the difference between this embodiment and the preceding embodiments is that the base 11 that each chain cloth 1 comprises can be a fabric, and the waterproof structure 13 can be all outer surfaces of the covering fabric, that is, the base 11 and The stamen 12 is completely covered by the waterproof structure 13 . The waterproof structure 13 can be, for example, a completely waterproof plastic material such as thermoplastic polyurethane (Thermoplastic polyurethanes, TPU).

Please refer to Fig. 6, the difference between this embodiment and the foregoing embodiments is that each chain cloth 1 may only include a core portion 12 and a waterproof structure 13, the waterproof structure 13 covers the core portion 12, and the thickness of the core portion 12 is greater than that of the waterproof structure 13 thickness. The waterproof structure 13 can be, for example, a completely waterproof plastic material such as thermoplastic polyurethane (Thermoplastic polyurethanes, TPU). Wherein, the appearance of the portion of the waterproof structure 13 that does not cover the core portion 12 may be similar to the appearance of the base portion 11 shown in FIG. 5 , but is not limited thereto.

Please refer to Fig. 7, the difference between this embodiment and the preceding embodiments is that the chain cloth 1 may only include a waterproof structure 13, and the waterproof structure 13 is divided into a base portion 131 and a pistil portion 132 according to different thicknesses; wherein, the pistil portion The thickness of 132 is greater than the thickness of base 131 . The waterproof structure 13 can be, for example, a completely waterproof plastic material such as thermoplastic polyurethane (Thermoplastic polyurethanes, TPU).

According to the above, the waterproof structure 13 of the chain cloth 1 shown in FIG. 4 is only provided on one of the wide sides 111 of the base 11, and this chain cloth 1 can be used in garments, as shown in FIGS. 5 to 7 The chain cloth 1 shown can be suitable for use in products that require waterproofing on both sides, such as ice packs, waterproof bags, and the like.

Please refer to Fig. 8 and Fig. 9, in the manufacturing process of the conventional waterproof zipper Z, the molten plastic material will enter the through hole Z11 of the cloth body Z1, and the high temperature material will enter the through hole Z11 of the cloth body Z1 When the through hole Z11 is deformed, and in the cooling process of the plastic material, the solidified plastic material may deform the side of the cloth body Z1, while the part of the cloth body Z1 that is not formed with the sprocket Z2 will not For this reason, the side Z12 of the cloth body Z1 will finally appear as an irregular wave shape. Since the two fabrics Z1 present irregular wavy sides Z12, they will eventually lean against each other to form a water-retaining wall. Therefore, it is obvious that the water-retaining wall formed by the sides Z12 of the two fabrics Z1 It will be difficult for the wall to be fully sealed, and external liquid will easily enter the other side of the waterproof zipper Z through the unsealed position of the side Z12 of the two cloth bodies Z1. For this reason, in the process of manufacturing the waterproof zipper Z, the relevant manufacturers must make the two abutting surfaces Z12 have a relatively large amount of interference through design, so that the waterproof zipper Z can achieve the same waterproof effect. When the abutting surface Z12 has a relatively large amount of interference, the sliding performance of the slide fastener will be deteriorated.

On the other hand, looking back at the waterproof zipper 100 of the present invention, the formation of each abutment surface 221 is basically only related to the design of the mold, and relevant personnel can easily control the flatness of the abutment surface 221. Therefore, the waterproof zipper of the present invention The 100 can have a relatively good waterproof effect when there is very little interference when the two abutting surfaces 221 abut against each other.

In a preferred application, the material of the chain tooth row 2 may include thermoplastic polyurethane (TPU) or TPU mixture, thermoplastic polyester elastomer (TPEE) or TPEE mixture, polyamide-based elastomer (TPA) or TPA mixture, Polyamide nylon (PA) or PA mixture, etc., and the material selected for the chain tooth row 2 can have relatively good elastic recovery force, good elongation (Elongation), compressibility (compression), tear The strength (tear strength) is acceptable, and has a certain tensile strength. More specifically, when the sprocket row 2 is meshed with each other, the two abutting surfaces 221 of the two connecting parts 22 will abut against each other, thereby achieving a waterproof effect. Therefore, when selecting the material of the sprocket row 2, choose Materials with relatively good elastic recovery force will allow the connecting portion 22 of the chain tooth row 2 to elastically deform when the chain cloth 1 is twisted by an external force, and return to its original state when the chain cloth 1 is no longer subjected to external force. The state when it is not twisted with the chain cloth 1.

In other words, if the sprocket row 2 is made of a brittle material, when the chain cloth 1 is twisted by an external force, the problem of breaking the connecting part 22 will easily occur; if any area of the connecting part 22 When the segment breaks, when the two sprocket rows 2 mesh with each other, external water will easily enter through the broken position of the sprocket row 2, resulting in a reduction in the waterproof effect of the waterproof slide fastener 100.

In practical applications, when producing long-sized waterproof zippers, it can be connected by two or more than three sets of molds, and the injection equipment can have multiple injection seats and nozzles, or it can be preceded on the chain cloth. The connecting portion and chain teeth of the injection part are then shot for the second or third time to continuously form another part of the connecting portion and chain teeth on the chain cloth.

In summary, the waterproof zipper of the present invention can achieve a better waterproof effect than the conventional waterproof zipper through the design of the connecting part, the abutting surface, and the chain cloth without any through holes, and the overall manufacturing process of the waterproof zipper Simple.

The above descriptions are only preferred feasible embodiments of the present invention, and do not limit the patent scope of the present invention.
