There are many applications of invisible zippers in clothing, mainly used in down jackets, denim jackets, leather jackets, high-end jackets, cold-proof clothing, etc. The invisible zipper consists of chain teeth, sliders, limit codes (front and rear) or locking pieces. The fastener element is the key part, which directly determines the side pull strength of the zipper. Generally, the invisible zipper has two pieces of chain belt, and each piece of chain belt has a row of fastener elements, and the two rows of fastener elements are arranged in a staggered manner. Compared with nylon zippers and resin zippers, they are stronger and more expensive, and are mostly used on jeans, jackets and backpacks. The following will introduce you to the maintenance of invisible zippers.
1. During normal use, pay attention to whether there are any defects such as “broken belly”, “tooth loss”, skew, etc. on the invisible zipper. If these defects are found, they should be repaired in time, and do not pull hard. If the zipper is loose and the teeth are loose, you can use a small hammer to tap the zipper head a few times to make the upper and lower chain teeth bite tighter, so that the teeth will not come off again.
2. The invisible zipper of aluminum alloy is more susceptible to corrosion, so it should be kept dry and not exposed to moisture to prevent the aluminum teeth from forming white oxides, which will cause the zipper to rust over time and affect the use. Contact with sexual and acidic substances. When storing, ensure a certain degree of ventilation, do not seal it, and do not store it in a humid environment. If necessary, use moisture-proof paper or dehumidifier. If the zipper becomes astringent when it is wet, at this time, first dry the zipper, then apply some wax on the teeth of the zipper, and then bake it with fire, so that it is very smooth when used.
3. When pulling the invisible zipper, you should first align the teeth on both sides, then hold the zipper head and gently pull it forward along the track. “. If the zipper is astringent and cannot be pulled flexibly, you can wipe it with a cloth first and then put a layer of white wax on the “teeth”.
Fourth, all kinds of bags, pockets or wallets with invisible zippers should not be overfilled, otherwise the zipper will easily cause “broken belly”, “tooth loss”, skew and soft cloth.
