Zipper quality management project

1. The specifications and models of the zipper

The specification of the zipper refers to the width and size range of the chain after the two connected teeth are joined. The unit of measurement is millimeters. The specification of the zipper is the basis for the shape and size of each component, and is the most characteristic and important size.

The zipper model is an important reflection of the shape, structure and performance characteristics. The zipper model not only includes the specifications of the zipper pull chain, but also reflects the performance characteristics of the pull chain, that is, the technical parameters and use functions of the zipper.

2．The strength 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 specified, and it is also the basis for testing the quality of the zipper. Different specifications and models of zippers have different strengths. 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. Zipper length

The length of the zipper relates to the size of the garment and the closed body or part of the garment, 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 measure from the top of the slider to the outer end of the bottom spigot, and the zipper to the outer end of the socket. During the production of the zipper, due to the inertia of the equipment and the integrity of the teeth, the length of the zipper is allowed there is a deviation, but it must be within a certain range.

4. The color of the zipper and zipper tape

The color of the zipper and zipper tape must be in accordance with the confirmation sample. If it is required to match the body color, 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 .
