When opening and closing the zipper, it does not move smoothly or catches the fabric？
--a) When sewing, if the stitching is too close to the elements, the slider will not have enough space to move, impeding its operation. Be careful to allow enough space.
--b) If the zipper catches because the fabric used is too thin or soft, you should put in a stitch or core to reinforce it.
Is there something I should be aware of when using a zipper for babies’ and kids’ products?
Special products/features, such as plastic stops, are available for babies' and kids’ products. Contact QLQ representatives for more details.
I have problems with metal zipper color changes？
--a) Metal parts may corrode depending on their storage conditions. There is a risk of the corroded parts staining the product, so products should be kept at low humidity, avoiding hermetically sealed storage in plastic bags or cardboard boxes and allowing some breathability in storage. (Please also be aware of the effects of NOX.)
--b) The use of cleaning products containing fluorine, or contact with fabric on which such cleaning products have been used, causes metal parts to become discolored. Please be cautious of this.
The zipper was bent during dry cleaning？
Repeated dry cleaning or high-temperature drying without closing the zipper will cause it to bend. Be sure to close the zipper before washing, drying or dry cleaning.
