Problems that need attention during the use of zipper

1. Contrasting color zipper (the fabric is inconsistent with the zipper tape, such as white fabric with black and red zipper tape) must be stated when placing the order, the color fastness must be good, and the zipper puller and slide must be tested before sewing to confirm that it can be large mass production;

2. Nylon zippers are used for PVC fabrics or waterproof/ski fabrics (when light-colored). Please note that the fabric will absorb oil stains in the zippers and cause stains on the fabric. When receiving similar orders, please specify when placing the order: zipper is required oil yield control, and test before putting into production;

3. White-plated nickel-free and rack-plated white nickel-free sliders are used for white cotton materials (such as wool products) that are easy to change color (such as yellowing, black, etc.), mainly because they are not cleaned after bleaching and dyeing. Caused by reaction with chemical residues. Please fully wash the fabric to a neutral state before production.

4. 8#, 10# resin, metal sliders, or large-volume pull tabs, round pull tabs are not effective in passing the needle. On the one hand, it is due to its large size, and the round pull tab will generate a magnetic field when testing the needle, which affects the effect of the needle detection test.

5. After washing and processing, the zipper self-locking slider is damaged. The zipper is washed while the zipper is open, and debris will enter the slider, making it easy to break. Therefore, please do the washing with the zipper closed. Alkaline detergents or chlorinated bleaches will melt the paraffin or oil film on the zipper. Please pay special attention when using it.
