The zipper on clothing should be used every day, and scientific use will prolong its service life. Here is how to use and protect the zipper on clothes.
When you zip up. First, the teeth on both sides must be close together and the top must be aligned. Then, hold the zipper head and pull it gently along the track, not too hard. When moving the zipper head, be careful not to screw impurities such as skirt or cloth edge into the zipper, so as not to cause tooth skew, broken belly and tooth loss. If the zipper is hard and difficult to pull, don't pull hard. You can put some wax or soap on the zipper and pull it.
There are basically three kinds of zippers: metal, nylon and plastic zippers. For aluminum alloy or copper zippers, be careful not to get wet during use and storage, and avoid contact with alkaline and acidic substances to avoid moisture, oxidation and corrosion of metal teeth. For nylon and injection-molded zippers, attention should be paid to preventing high temperature to avoid deformation. Because its wear resistance, hardness and strength are not as good as metal zipper, it should be used more carefully than metal zipper. Be sure to gently extract the tooth.
If the zipper fails in use, it must be repaired in time. Metal zipper has the phenomenon of missing teeth or skew, which can be used by removing bad teeth and adding new teeth. When the zipper is pulled up, the teeth on both sides are not closed, indicating that the zipper is loose after wearing it. You can use a common vise to gently clamp the closed end of the zipper head horizontally, and the zipper will get better immediately, and the teeth on both sides will be tight and will not come loose again. If the zipper head cannot be pulled, it means that the clamping force is too large and must be readjusted; Some zippers have lost teeth at both ends, so the lost teeth can be separated, the zipper head can be moved inward, and the end can be fixed with needle and thread to continue to use; If the teeth and zipper head of the zipper are not metal, they can't be repaired if they are broken, so they have to be updated.
