Embodiment 1

[0027] refer to figure 1 , a production method of a curved slide fastener, the present embodiment is specifically a curved slide fastener with an S-shaped structure, comprising the following steps:

[0028] 1. Make a zipper tape a for carrying pairs of fastener elements, the zipper tape a is made of cotton yarn, chemical fiber or mixed chemical fiber, which contains 30% TPU material;

[0029] 2. The side edge of the opposite side of the paired zipper tape a prepared in step 1 is added with a single-strand chain element by weaving. High, low temperature and wear resistance;

[0030] 3. After step 2, carry out ironing treatment on the two zipper tapes a, the ironing temperature is between 160°C and 180°C, specifically 160°C is used here;

[0031] 4. Coating sizing agent on the front and back sides of the two zipper tapes a;

[0032] 5. Put the two zipper tapes a coated with the sizing agent into the forming mold for stretching and forming, and perform high-frequency treatment...

Embodiment 2

[0041] refer to figure 2 , compared with Embodiment 1, the curved zipper produced by this embodiment has a C-shaped structure. At this time, the number of groups of pulling sliders 1 is three groups, and the pulling sliders 1 on both sides are inclined and symmetrically arranged. , the pulling slider 1 in the middle is set perpendicular to the length direction of the two zipper tapes a. When the pulling is in progress, the running directions of the three groups of pulling sliders 1 are the same (that is, common upward or downward), so that the two zipper tapes 1 Under the action, it forms a circular arc shape bent along the running direction, which is a C-shaped structure.

Abstract

The invention relates to the field of zipper products, in particular to a curved zipper production method. The curved zipper production method comprises the following steps: 1, manufacturing paired zipper cloth strips used for bearing zipper teeth, wherein the zipper cloth strips are made of cotton yarns, chemical fibers or mixed chemical fibers and at least comprise 30% of a TPU material; 2, adding single-stranded or double-stranded zipper teeth on the side edges of the opposite sides of the paired zipper cloth strips manufactured in the first step through weaving or sewing; 3, finishing andironing the two zipper cloth strips after the second step, wherein the finishing and ironing temperature is 160 DEG C to 180 DEG C; 4, coating the front surfaces and the back surfaces of the two zipper cloth strips with a setting agent; fifthly, putting the two zipper cloth strips coated with the setting agent into a forming die for drawing and forming, and carrying out high-frequency treatment, wherein the temperature of the high-frequency treatment is 140-150 DEG C, and the treatment time is 8-10 seconds. The curved zipper production method is applied to the production of curved zipper products, and provides a complete and high-efficiency production process.

Description

technical field [0001] The invention relates to the field of zipper products, in particular to a production method of a curved zipper. Background technique [0002] With the development of living standards, consumers have more requirements for the appearance of clothing and bags. The openings of many products on the market are designed in a curved shape, but the zippers in contrast are mostly linear structures. When the product structure needs to be bent, the zipper needs to be bent and then sewed artificially. It is difficult to process, and at the same time, the zipper teeth are easily deformed due to artificial bending, resulting in a decrease in the durability of the zipper, especially for some zippers with special functions, such as waterproof zippers, which are very likely to damage the zipper here. Waterproof and airtight. For example, the Chinese patent CN201620032205.2 with an application date of January 12, 2016 discloses a curved zipper, which includes a zipper ...
