How to distinguish different types of zippers and how to tell what size the zipper is

Dizzy, this one doesn't sell very well.

Generally, there is a number engraved on the back of the slider. 3 is 3, 4 is 4, 5 is 5, and so on

However, there is also a written slider on the back of the head is not engraved. Then you will understand it after a long time of daily contact. It's not hard.

This needs to be told by the garment manufacturer, I make zippers. We can work together! Hehe.

The number behind the slider is the model number of the zipperUsually zipper model 3 4 5 8 10 resin zipper extra large model 20 30. If there is no number behind the slider, the width of the zipper teeth is 3.

Maintenance of the zipper:1. When using it at ordinary times, pay attention to whether the zipper has problems such as "broken belly", "teeth", and crookedness, and repair these problems in time, and do not pull hard. If the zipper is loose and the teeth are missing, you can use a small hammer to gently tap on the zipper head a few times, so that the upper and lower teeth bite a little tighter, and the teeth will not fall out.

2. The zipper of aluminum alloy is more likely to corrode, so it should be kept dry and not in contact with moisture to prevent aluminum oxidation from generating white teeth, which will cause the zipper to rust and affect the use, but also be careful not to contact alkaline and acidic materials.

Judging by the combined width of the teeth:

Metal zipper. Nylon zipper.

Resin zippers.

Tips for maintaining zippers.

1. When using it at ordinary times, it is necessary to pay attention to whether there are "broken belly", "tooth loss", crooked and other problems on the zipper.

2. The zipper of aluminum alloy is more susceptible to corrosion, so it should be kept dry and not damp, in order to prevent the aluminum teeth from generating white oxides, which will cause the zipper to rust over time and affect the use, and at the same time, it should also be noted that it is not in contact with alkaline and acidic substances.

3. When pulling the zipper, you should first align the teeth on both sides, and then pinch the zipper head and gently pull forward along the track, do not pull hard, so as not to cause "tooth loss". If the zipper is astringent, you can wipe it with a cloth first and then put a layer of white wax on the "teeth".

4. All kinds of bags, pockets or wallets with zippers should not be overfilled, otherwise it is easy to cause the zipper to cause "broken belly", "tooth loss", crooked and soft cloth.

The base of the zipper puller will have specifications, such as 3, 5, 8, representing 3 zipper sliders, 5 zipper sliders, and No. 8 zipper sliders. The size parameters of the zipper head are mouth height and mouth width, which represent the width and height of the zipper pull, respectively.

Zipper is a connector that relies on a continuous arrangement of teeth to merge or separate items, and is now widely used in clothing, bags, tents, etc.

1. A fastener composed of a row of metal teeth or plastic teeth on each of the two belts is used to connect the edge of the opening (such as clothes or bag mouths), and a sliding piece can pull the two rows of teeth into the interlocking position to close the opening;

2. A chain attached to something (as an object being lifted or dropped) to tighten, stabilize or guide the object.

The slider of the zipper is indicated.

If you take a closer look, you'll find out.

The classification of zippers is classified according to the specifications and the size of the operation process, the model and the size of the zipper teeth are directly proportional to the specific look.

Judging by the width of the teeth:

metal zipper

Metal Zipper 3

#####nylon zipper

Nylon zipper 3

#####derlin zipper

Resin zipper 3

1.The number behind the slider is the model number of the zipper2.Usually zipper model 3 4 5 8 10 resin zipper extra large model 20 30 3If there is no number behind the slider, Bu Chang will put the zipper teeth together and sell the wide and medium matching 3.

Look at the number behind the slider.

That is the model of the zipper, if there is no number on the surface of the slider after the slider, the model of the zipper is the width of the combined zipper. The model of the zipper is so large, and the size of the model is generally proportional to the size of the zipper teeth.

There are 3 main types of zippers:

1. Closed zipper.

The rear yard is fixed and can only be pulled away from the front yard end.

2. Open zipper.

There is no back code at the lower end of the zipper, and the lock is fastened.

3. Double open zipper.

There are two sliders that can be opened or closed from either end.

How the zipper works:

It is generally explained by the principle of resultant force and component force when the zipper is opened, the triangular object moves with the zipper between the two chains, and the pull force of the hand produces two component forces on the triangular object. In the case of a small angle, the force acting on the sharp angle is very large, and the two-component force exerts force on the zipper and the component force is greater than the vertical downward resultant force, that is, the component force is greater than the stuffy spring pull force of the hand, so the zipper that is difficult to separate directly is easily separated by the triangle.

Zippers are used in a wide range of applications. According to the material of the zipper, the zipper is divided into three categories, metal zipper, resin zipper, and nylon zipper. <>
