Technical Field

The invention relates to the technical field of zippers, in particular to a waterproof zipper with tooth paste and a preparation method thereof.

Background

A conventional slide fastener has a pair of tapes, one side of each tape has a corresponding tooth (or tooth), the tooth is sewn to the tape by a sewing thread, and a slider is provided on the tooth, and the tooth can be opened and closed by the slider (see fig. 3, in which 1 is a tape, 2 is a tooth, 6 is a sewing thread, and 7 is a slider).

The waterproof zippers appearing in the market are generally provided with a cloth belt surface coated with glue and/or pasted with a waterproof film to achieve the function of preventing water splashing, but teeth on the tooth surface are exposed and cannot be waterproof, and water can permeate into a central line from tooth gaps to form accumulated water. In the market, the method of glue filling in the teeth is also adopted, and waterproof is realized by filling tooth gaps through glue filling treatment, such as patent CN 202010742304.0; however, the teeth subjected to the glue filling treatment are mainly used for a reverse zipper, and the effect of the forward zipper (the teeth are exposed on the front surface) is not good, and the appearance is not attractive. In addition, still appear in the market in the technical scheme (TW107205705) of the little cloth of nylon tooth surface seam, can block the gap of tooth, the function of preventing splashing is slightly better than individual tooth suture, but the main objective is to play the purpose such as hiding the sprocket, protecting the suture, change the zip fastener colour, change the zip fastener molding, the cloth still can not be waterproof, even the cloth is through waterproof soaking treatment, the pinhole time of stylolite also can seep water, it is still far from not enough to waterproof the effect.
