If the backpack zipper is used improperly or for a long time, it is inevitable that there will be problems. If there is a problem with the zipper of the backpack but you don't know how to solve it, it can affect the use of the backpack at a light level, and at a heavy level, it can lead to the loss of the belongings inside the bag. So, what if there is a problem with the backpack zipper? Do you know the solution?
1. Zipper missing teeth
Pry open the zipper teeth at the original tail with a pointed mouth or a camera to remove a few teeth, install them at the tooth loss area, and then gently press the tooth opening onto the edge of the cloth with a pointed mouth to make it bite firmly.
2. The zipper won't move
Sometimes the zipper won't open, or it won't move halfway, because the teeth of the zipper are crooked or the fibers of the fabric belt are loose. If the teeth of the lock are crooked, you can first use a steel needle to straighten them, then flatten them, and then use a small hammer to gently flatten the teeth of the lock. The lock will work fine. If the fabric straps are loose, the ones that do not match can be forcefully pulled by the canthus, so that the teeth of the lock are evenly arranged and can be pulled.
3. The zipper is not smooth
One is that the chain teeth are rusted or contaminated with dust and dirt; The second reason is that something like fabric edges is sandwiched in the logic. The former only needs to be lightly rubbed with paraffin on both sides of the zipper to ensure smooth and comfortable operation; For the latter, the key head should be slowly returned to its original position to remove any foreign objects.
4. Zipper cannot close
Due to prolonged use, the distance between the upper and lower pieces of the chain head has been adjusted or changed. Just use pliers to clamp it up and down or left and right, but be careful not to use too much force to avoid damaging it.
5. Zipper Slippery Tips
After the zipper is damp, rusty, or oxidized, it is not smooth to pull and cannot be pulled with force. If you use a candle to rub back and forth between the two rows of zipper teeth and bake it on the fire, it will be very smooth to pull.
6. After the zipper is closed, it will explode on its own
This kind of problem is because the pulling head is too long and the caliber becomes larger. If you want to solve it temporarily, just use pliers to clamp the tail of the pulling head. Pay attention to the tail, but be careful not to use too much force or clamp too far. If you want to completely solve it, you need to replace the pulling head.
