However, no matter what kind of slider, it is necessary to feel whether the pull of the slider is free, and whether the zipper can not be pulled or closed. The resin sliders currently on the market are equipped with self-locking devices, so after pulling the zipper, it is necessary to check whether the zipper will slide down when the lock is fixed. 3, the choice of cloth: Because the raw material of the resin zipper tape is made up of different kinds of silk threads such as polyester thread, stitch, and core wire, its component and colorability are different, so it is easy to produce chromatic aberration on the same zipper.
