How to identify the pros and cons of zippers?
1、Method Straightness of zipper
The test method for the straightness of the zipper is: take a finished zipper, place it flat on a flat table, make it in a natural state, and then use your fingers to move back and forth along the sides of the chain teeth once, and use a straightedge to gradually move closer to the bend. , And then use another ruler to measure the distance between the foot of the chain and the ruler, this distance is the straightness.

2、The power of the zipper
The strength of the zipper is the most important performance indicator, which determines the scope of use and durability of the zipper. In the zipper standards of various countries, the strength is clearly stipulated, and it is also the basis for testing the quality of the zipper. Different specifications and models of zippers have different strengths and suits. For different purposes, the zipper supplier will generally give a reference selection of specifications and models of use. The specifications and models of the zipper must meet the requirements for use. Once confirmed, the specifications and models must meet the requirements of the order.
3、The size of the zipper refers to the width and size range of the chain after two connected teeth are joined. The unit of measurement is millimeters. The size of the zipper is the basis for the shape and size of each component, and is the most important size with the most characteristics. The type of the pull chain is the shape. , An important reflection of the structure and performance characteristics, the pull chain model not only includes the pull chain specification requirements, but also reflects the pull chain performance characteristics, that is, the technical parameters and use functions of the zipper.
4、Color of zipper and zipper tape
The color of the zipper and zipper tape must be consistent with the confirmation sample. If the body color is required, check it again with the fabric. At the same time, check whether the same zipper has color difference, and whether the same batch of zippers has color difference, generally should be above GRADE3 .
5、Zipper length
The length of the zipper relates to the size of the clothing and the closed body or part of the clothing, and is the most important size. The method of measuring the length of the zipper is: place the zipper flat on a flat table to make it in a natural state, and use a steel ruler to measure the length of the zipper. Measure from the top of the slider to the outer end of the bottom stop, and measure to the outer end of the socket for the open-end zipper.
In the process of making the zipper, due to the inertia of the equipment and considering the integrity of the teeth, the length of the zipper is allowed to vary, but it must be within a certain range.
