What should I do if the zipper of my bag is difficult to pull?

People usually use all kinds of bags, such as school bags used by students, small bags often carried by girls, or briefcases used by working people, etc. There are many styles of these bags, which can be said to be varied, but almost all of them have one thing in common, that is, there are zippers on the bags. If the zipper on the bag is not easy to pull, the performance of the bag will be greatly reduced. So what are the ways to solve this problem?

What should I do if the zipper of my bag is difficult to pull?

1. When the opening and closing is not smooth, if you pull the chain head hard, it will cause tooth bite failure. At this time, apply paraffin or lubricating spray [FASTENERMATE] to the surface and inside of the teeth, then move the slider several times and it will slide easily.

2. If the zipper on a bag that is filled with too many things is closed, the zipper will be subjected to too much force and the teeth will detach from the belt. This is considered a serious zipper failure. Pull the left and right teeth together to make it easier for the chain head to pass through and close the zipper. It is best to take out some of the contents of the bag and not overfill it.

3. When opening and closing the zipper, sometimes the chain head bites the thread segment or fabric and the slider cannot be pulled. If you forcefully pull the slider, the bite will get deeper and deeper. You should push the slider back while untying the fabric. When it is fully bitten in, do not pull the slider with force, but slowly pull it back. Also, do not leave any hidden dangers when sewing the zipper.

How to maintain zippers in daily life?

During normal use, pay attention to whether the zipper has defects such as "broken belly", "loose teeth", or crookedness. If there are these defects, repair them in time and do not pull them hard. If the zipper is loose and has dislocated teeth, you can use a small hammer to gently tap the zipper head a few times to make the upper and lower teeth bite tighter, and it will not dislocate again.

Aluminum alloy zippers are more susceptible to corrosion, so they should be kept dry and away from moisture to prevent the aluminum teeth from generating white oxide, which will corrode the zipper over time and affect its use. At the same time, care should be taken to avoid contact with alkaline and acidic substances.

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

When pulling the zipper, you should first align the teeth on both sides close together, then pinch the zipper head and gently pull it forward along the track. Do not pull it hard to avoid causing "crooked teeth", "broken belly" and "loose teeth". If the zipper feels stiff and difficult to pull, you can first wipe it clean with a cloth and then apply a layer of white wax on the "teeth".
