Basic knowledge about zippers

Commonly used identification methods for zipper quality

1. Cloth tape: The color should be uniform, with no stains, no scars, soft to the touch, flat in the vertical or horizontal direction, and slight waves allowed.

2. Teeth: The surface of the teeth should be smooth, feel smooth when pulling, and make little noise.

3. Slider: The self-locking slider can be pulled easily and locked without slipping.

4. Cloth patch: The cloth patch is tightly buckled with the cloth belt and is not easy to break or fall off.

5. Square: The pin can be inserted freely to fasten the cloth belt.

6. Top stop: The top stop should be tightly buckled or close to the first tooth (metal, nylon), but the distance should not exceed 1mm and it should be strong and perfect.

7. Lower stop: The lower stop is fastened to the teeth or pliers and is strong and perfect.

Special requirements

1. Make it clear which type of product the zipper is used in (such as suitcases, leather boots, windbreakers, raincoats, tents, heavy-washed jeans, or leather products with high acidity) or other special requirements.

2. Requirements for zipper components, whether they need to be azo-free, nickel-free, or require a needle detector.

3. Dyeing standards are divided into ordinary rinse, fixation, and special fixation.

4. Requirements for zipper dyeing: If the zipper is different from the color of the fabric, you must discuss it first.

5. When two zippers are to be combined (mutually chained), they must be discussed first.
