Description

Nylon zipper with strong tensile property

Technical Field

The utility model relates to a zip fastener field specifically is a nylon zip fastener that tensile strength is strong.

Background

Slide fasteners are connecting members for joining or separating articles by means of continuously arranged fastener elements, and are widely used for clothing, bags, tents, and the like.

Zippers are classified into three categories according to their materials: metal zippers, resin zippers and nylon zippers. The metal zipper teeth are discharged through a tooth arrangement machine by using a copper wire or an aluminum wire, the resin zipper teeth are color-matched by using polyester plastic rice through a dye and discharged through an injection molding machine, and the nylon zipper teeth are formed by winding a central line by using a nylon monofilament through a heating and pressing mold. Compared with metal zippers and resin zippers, the nylon zipper has the characteristics of low cost, high yield and high popularization rate.

The nylon zipper has the advantages of low manufacturing cost and application range pipe, and is easy to wear between the zipper teeth and the cloth belt in the long-term use process, so that the zipper teeth and the cloth belt are broken to cause the damage of the nylon zipper.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve prior art's nylon zip fastener at the in-process of long-term use, wearing and tearing appear easily between chain tooth and strap, the fracture between chain tooth and the strap appears, leads to the damage problem of nylon zip fastener, provides a nylon zip fastener that pull resistance is strong.

The utility model discloses a following technical scheme realizes:

the nylon zipper with high tensile strength comprises two cloth belts, wherein zipper teeth are arranged on the inner sides of the two cloth belts, reinforcing belts are sewn on the upper surfaces and the lower surfaces of the zipper teeth, and the zipper teeth and the reinforcing belts are sewn through sewing lines.

Preferably, the zipper teeth positioned on the opposite inner sides of the cloth belts are arranged in a staggered mode.

Preferably, a part of the fastener elements are arranged to overlap with the cloth tapes, and the other part of the fastener elements are arranged to protrude from the cloth tapes.

Preferably, the reinforcing tape is located on the outer surface where the fastener elements overlap the cloth tapes.

Preferably, the number of the sewing threads on a single cloth strip is two.

Preferably, the suture is 0.68mm monofilament.

Compared with the prior art, the utility model, following advantage and beneficial effect have:

the utility model discloses an add the strengthening band, provide the protection to the chain tooth, reduce the wearing and tearing in the use, prevent that the zip fastener is impaired, increase of service life, stylolite adoption even number sets up simultaneously, further strengthens the steadiness between chain tooth and the strap, and lifting strength promotes the pull resistance, further protects structural integrity.

Drawings

The accompanying drawings, which are included to provide a further understanding of the embodiments of the invention and are incorporated in and constitute a part of this application, illustrate embodiment(s) of the invention and together with the description serve to explain the principles of the invention. In the drawings:

FIG. 1 is a schematic structural view of the present invention;

fig. 2 is a cross-sectional view of the present invention;

designations in the drawings and names of corresponding parts:

in the figure: the zipper comprises a cloth belt 1, zipper teeth 2, a suture line 3 and a reinforcing belt 4.

Detailed Description

To make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the following examples and drawings, and the exemplary embodiments and descriptions thereof of the present invention are only used for explaining the present invention, and are not intended as limitations of the present invention.

Examples

As shown in fig. 1-2, a nylon zipper with high tensile strength comprises two cloth tapes 1, wherein two of the cloth tapes 1 are arranged, zipper teeth 2 are arranged on the opposite inner sides of the two cloth tapes 1, reinforcing tapes 4 are sewed on the upper surfaces and the lower surfaces of the zipper teeth 2, and the zipper teeth 2 and the reinforcing tapes 4 are sewed through sewing threads 3.

The suture 3 is used for enhancing the connectivity between the zipper teeth 2 and the reinforcing belt 4 and enhancing the stability.

Furthermore, the zipper teeth 2 positioned on the opposite inner sides of the cloth belts 1 are arranged in a staggered mode.

The elements 2 are arranged offset to ensure the mutual engagement effect.

Further, a part of the fastener elements 2 is arranged to overlap the tape 1, and the other part of the fastener elements 2 is arranged to protrude from the tape 1.

Further, the reinforcing tape 4 is arranged on the outer surface of the overlapping part of the fastener element 2 and the cloth tape 1.

The reinforcing belt 4 is of a half-wrapping structure, and the effect of the chain tooth 2 with the protection effect is improved.

The reinforcing belt 4 is used for protecting the stability between the zipper teeth 2 and the cloth belt 1 and protecting the reinforcing belt 4.

Further, the number of the sewing threads 3 on the single cloth tape 1 is two.

Two stability that set up stylolite 3 and be used for strengthening between strap 1 and the chain tooth 2, the single strip stylolite 3 appears becoming flexible easily in long-term use, and two stylolite 3 can effectively reduce not hard up problem, lifting strength.

Further, 0.68mm monofilament is used for the suture 3.

The suture 3 adopts a four-needle eight-thread suture process, and because the double suture 3 is arranged, a 0.68mm monofilament with the thickness less than the conventional 0.74mm is adopted, so that the tensile resistance is stably improved.

Meanwhile, the reinforcing belt 4 can also adopt a color different from that of the cloth belt 1, so that the color difference is enhanced, the color collision effect between the reinforcing belt 4 and the cloth belt 1 is formed, the identification degree is improved, and the attractiveness is added.

The above-mentioned embodiments, further detailed description of the objects, technical solutions and advantages of the present invention, it should be understood that the above description is only the embodiments of the present invention, and is not intended to limit the scope of the present invention, and any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
