The English name of the Invisible zipper is "Invisible zipper", which is composed of chain teeth, pull tabs, limit codes (front and rear codes) or locking parts, etc. Among them, the chain teeth are the key part, as they directly determine the side pull strength of the zipper. Generally, an invisible zipper has two chain straps, each with a row of teeth, and the two rows of teeth are arranged alternately. Invisible zippers are mainly used in down jackets, denim clothing, leather jackets, high-end jackets, cold-proof clothing, etc. Compared with nylon zippers and resin zippers, they are more sturdy and have a higher cost. They are mostly used on jeans, coats and backpacks. Today, I'd like to share with you the methods on how to protect invisible zippers well

1. In daily life:

In our daily life, we often come into contact with zippers, and sometimes we even get annoyed by them. Because we often encounter situations where the zippers on our clothes break down shortly after purchase. The zipper on the child's clothes has fallen off. The plug rod has fallen off. Some issues such as the cloth tape coming apart from the stick and so on. In fact, if we pay a little attention in our daily life, we can avoid similar situations from happening

In daily life, what can cause significant damage to zippers is when washing clothes. Usually, we may not pay attention and directly put clothes with zippers into the washing machine. During the washing process, due to the force exerted on the clothes, they will keep rolling inside the washing machine, and the zippers will constantly rub or collide with the inner walls of the machine. At this time, if the zippers are not properly protected, Some small components, such as the box body and the plug rods, may get stuck in certain parts of the machine (for example, the drain hole of the washing machine). After being constantly pulled or twisted, these small components may shift or fall off.

Also, when washing clothes, if there are clothes with zippers in the laundry, try not to wash too many of them together. This is because a large number of clothes will increase the contact force between the zippers and the inner wall of the machine, intensifying the severity of friction.

When getting dressed in daily life, don't be in a hurry. After the zipper stick is inserted into the zipper box, pull it gently. Pulling too fast may hurt yourself or pinch the clothes. If you don't stop pulling after pinching the clothes, it may cause the zipper piece to break. In severe cases, it may lead to the zipper coming out of the groove and damage the pull head. When the pull TAB gets stuck on the clothes, stop pulling immediately, then tilt the pull TAB backward and slowly pull out the clothes. This can prevent damage to the pull and extend the service life of the zipper.

In addition to the above aspects, we should also maintain the zipper on a regular basis, apply wax or other maintenance products to protect your zipper.

2. In the production and processing of zippers:

During the production and processing in factories, in order to achieve certain special effects or design requirements for clothes, some processing treatments are carried out after the finished garments are made. Among them, the "washing" process is very common.

During the water washing process, some forces generated inside the washing machine can cause the zipper to be forcibly opened. The influence of external forces such as pulling can lead to damage or detachment of the chain teeth.

Cause of damage: When the zipper is not fully closed before water washing and is subjected to external force during the washing process, the teeth inside the zipper are pulled by the zipper. When the external force exceeds the strength it can withstand, the teeth will fall out or be lost.

At this point, the pull head may also fall off due to the detachment or displacement of the chain teeth, creating gaps. Friends who are engaged in these processing should pay attention. When we are going to wash the ready-made clothes, we must fully close the zipper, pull the zipper to the top and fix it.

In addition, there are also cases where light stones or other solid substances are added to the washing machine to achieve a whitening effect on the fabric. These small stones roll back and forth during the washing process. Due to their being hard solids, they can scratch the components or surface treatment layer of the zipper, exposing the base color of the components. So at this point, the pull head should be wrapped in cotton cloth and sewn onto the fabric or cloth for fixation.

So when we do laundry in daily life, we should try to pull up the zipper and keep it closed, or wrap and fix the zipper pull and the end of the zipper with cotton cloth when washing. In this way, during the washing process, the pull head will not come into direct contact with the inner wall of the machine and will not constantly collide. The service life of the pull head will be much longer than that of an irregular one.

After the bottom of the zipper is wrapped, the plug or the box will not enter certain parts inside the washing machine, and thus the pulling phenomenon will not occur. The cloth tape will not easily separate from the plug and the rod.
