Introduction to Resin/Plastic Zipper
Resin zipper is a type of zipper made mainly from synthetic resins such as polyester (POM) or nylon. Due to its durability, waterproofness, and diverse design, it is widely used in clothing, luggage, outdoor products, and other fields. Compared with traditional metal zippers and nylon zippers, resin zippers have both functionality and aesthetics, becoming an important accessory in modern manufacturing.
1. Materials and StructureThe teeth of the resin zipper are injection molded from high-density polyester material, which has excellent wear resistance and corrosion resistance, while being lightweight. Chain belts are usually woven with polyester fibers, which have high strength and are not easily deformed. The pull tab is mostly made of metal or resin material, and the surface can be electroplated or sprayed to enhance its aesthetic appeal.
2. Characteristics and advantages
Waterproof and rust proof: The resin material is non absorbent and suitable for use in damp environments such as swimwear and rain gear.
Good flexibility: The chain teeth can bend and fit the fabric, commonly used in sportswear and casual wear.
Rich colors: Multiple colors can be achieved through dyeing to meet personalized design needs.
Lightweight and durable: lighter than metal zippers, and acid and alkali resistant, anti-aging, long service life.
3. Application Fields
Resin zippers have a wide range of applications:
Clothing: Down jackets, jackets, jeans, etc., especially suitable for clothes that require frequent washing.
Luggage: travel cases, backpacks, etc., due to their strong impact resistance.
Outdoor equipment: tents, sleeping bags, etc., rely on their weather resistance.
Safety protection: Some products add reflective strips for use in workwear or outdoor safety equipment.
4. Classification and selection
According to function, it can be divided into open zipper, closed zipper, invisible zipper, etc. When purchasing, attention should be paid to the density of chain teeth (such as size 3 and 5 representing tooth size), the type of slider, and whether special functions (such as fire resistance and UV resistance) are required.
5. Maintenance and upkeep
Avoid prolonged exposure to sunlight or strong acids and alkalis. When cleaning, it is recommended to close the zipper to reduce the risk of chain deformation.
In short, resin zippers have become an important choice in modern industry due to their practicality and aesthetics. In the future, with the advancement of material technology, their application scenarios will further expand.
