Fashion Zipper is one of the important accessories of clothing. The zipper is related to the functionality of the garment. A qualified zipper ensures the aesthetics and functional requirements of the garment. Therefore, pay attention to the correct inspection of the quality of the zipper when using it.

For Plastic Zipper, first look at its appearance, including whether the color of the zipper is bright, whether the color of each component is consistent, whether there is obvious color difference; whether the fabric has colored flowers, dirt and wrinkles. There are also whether the surface of the element is shiny, whether the middle part of the front of the element is sunken, whether there is overflow in the root of the element, and whether there are obvious quality problems such as missing teeth and toothlessness. The head of one end of the portable zipper is flat, flat, wavy or curved when the zipper is in a natural hanging state. Whether the adhesive position of the tape is symmetrical, and whether it is skewed or floating. Whether the trademarks on the bottom of the slider and the front of the slider are clear.

Then check the feel of the Plastic Teeth Zipper, pull the slider back and forth with your hands back and forth, and the jump of the slider is normal. When the slider is activated at the bottom stop and the socket, it is normal to feel stuck or obstructed. Whether the slider can be flipped flexibly within 180 °; When inserting or removing the latch, the hand feels light and flexible; pull the slider upward by hand perpendicular to the plane of the slider body so that the slider cap cannot be loosened or detached .

The pull tab is naturally placed on the zipper, and the two fastener belts are pulled apart with two forces at an angle greater than 60 °. The applied pull force should not be too large or too strong. In this case, the slider does not slide, indicating that the slider has Locking effect. If the slider slides, it means that there is no lock or the self-locking force is not strong enough.

For Nylon Zippers, in addition to the common points with Large Plastic Zippers, it is also necessary to see whether the teeth of the fastener elements are broken, which will affect the flat pull strength of the zipper. Whether the position of the core wire and the suture is appropriate, whether there is a chain element reverse stitching, whether there is reunion, or needle skipping; the suture should be sewn on the core wire.
