The Basic Knowledge of Zipper Slider

Zipper is one of the important accessories of clothing. Qualified zippers meet the aesthetic and functional requirements of clothing, so we should pay attention to the quality of zippers when using them. For plastic zippers, we need to check whether the surface of the chain teeth is shiny, whether the middle of the front of the chain teeth is sunken, whether the root of the chain teeth is overflowing, whether there is a lack of teeth and other obvious quality problems. Then we should pull the zipper slider back and forth with our hands and feel the puller pulsing. If there is no pulsation, it is normal. And it is normal to feel stuck or blocked when the puller is started at the top and bottom stops. As an important part of zipper, zipper slider is an important standard to check the quality of zipper. Therefore, it is necessary for us to understand the basic knowledge of zipper sliders.

What is a zipper slider?

The zipper slider is the main part of a zipper. It is widely used in daily life, such as waterproof zipper tape, zipper hoodies and so on. It consists of two inlet ports, one mesh outlet, upper plate and lower plate. The upper plate has a nose-like part attached to the lower plate. When we say nylon zipper slider, plastic zipper slider and metal zipper slider, we don't mean the material of zipper head, but the material of zipper teeth

Classification of zipper sliders

We refer to the auto lock invisible zipper slider as self-lock slider for short. Under the action of elastic force, a small self-locking baffle can be embedded into the chain teeth automatically to lock the zipper slider. When the zipper is opened or closed, it can lift the pull-tab to drive the small retaining piece out of the chain.

The pull-tab of the needle lock zipper slider has 1 or 2 stops. When the pull-tab is pressed down, the needle is inserted into the chain teeth and the zipper slider is fixed. It is usually used in pillows or shoes, while the invisible zipper slider is used in tight women's clothing.

Maintenance of zipper slider

In our daily life, we should pay attention to the zipper slider whether there are teeth off, skew and other defects. If there are these problems, you should repair them in time and not pull them hard. 

If the zipper slider is loose, we can gently tap the zipper slider with a small hammer to make the upper and lower chain teeth clamp tightly, so that the teeth will not come off again.

Aluminum alloy zipper slider is easy to be corroded. Therefore, we should keep the environment dry to prevent it from forming white oxide. At the same time, we should also pay attention not to contact with alkaline and acidic substances.
