What to do if the zipper breaks in the middle? Tips for maintaining the zipper

Sometimes when you pull the zipper, the zipper may break in the middle. The reason for this is that the spacing between the copper sheets has been widened. Just use pliers to clamp the opening of the slider.

Use pliers to clamp the opening of the zipper until it is just right, but not too tight! Don't clamp the zipper too hard when clamping it with pliers, as it may damage the zipper. Don't clamp the zipper too tightly, as it will not be smooth and hard to pull. If the zipper is really not clamped well, you can only go to a tailor shop to replace it.

1. When using the zipper, pay attention to whether it has any defects such as "broken belly", "loose teeth", or crookedness. If there are any such defects, repair them in time and do not pull them hard. If the zipper is loose or has lost teeth, use a small hammer to gently tap the zipper head a few times to make the upper and lower chain teeth bite tighter, and it will not lose teeth again.

2. Aluminum alloy zippers are more susceptible to corrosion, so they should be kept dry and not exposed to moisture to prevent the aluminum teeth from generating white oxides, which will cause the zipper to rust over time and affect its use. At the same time, be careful not to contact with alkaline and acidic substances. When storing, ensure a certain degree of ventilation, do not store in a sealed state, and do not store in a humid environment. If necessary, use moisture-proof paper or dehumidifier.

If the zipper feels rough when pulled after being damp, first expose the zipper to the sun, then apply some wax on the teeth of the zipper and then melt it with fire. This way, it will be very smooth to use.

3. When pulling the zipper, you should first align the teeth on both sides, then pinch the zipper head and gently pull it forward along the track. Do not pull it hard to avoid "teeth crooked", "broken belly" and "tooth loss". If the zipper is stiff and not flexible, you can first wipe it with a cloth and then apply a layer of white wax on the "teeth".

4. Do not overfill bags, pockets or wallets with zippers, otherwise the zippers may easily become "broken", "loose", skewed or the fabric may become soft.

If the zipper is stuck or not smooth, you can use wet soap to repeatedly rub the stuck and not smooth part of the zipper. Soap can make the zipper smoother. When the zipper is no longer stuck, use clean water or a clean wet cloth to clean the part rubbed with soap. Detergent, hand soap, laundry detergent, candles and other lubricating substances can be used instead of soap.

1. Nowadays, many zippers are made of aluminum alloy. Although this material is not as easy to rust as iron, it may cause oxidation and rust in a humid environment for a long time. Therefore, zippers should be placed in a dry place to avoid moisture. Also avoid contact with acidic and alkaline substances, which can easily corrode zippers.

2. Do not overfill zippered bags when using them. Too many things can easily cause the zipper to break. Do not force inappropriate zippered clothes, which can also easily cause the zipper to burst.

3. When pulling the zipper, you should pull it slowly and not too impatiently. First align the teeth at both ends of the zipper, then pinch the zipper head and pull it gently along the track. If there is a problem with the zipper, do not pull it hard.
