When it rains, we always feel very melancholy when we go out. Umbrellas are easy to use, but God is still satisfied when we are wet.
People are always worrying, but they are always trying their best to avoid God's mischief. The witty people began to develop the road of waterproof products. Nowadays, waterproof materials are gradually used in clothing, umbrellas, watches, bags and other industries to make products, which does not give God any face. We in the zipper industry, too, quietly built waterproof zippers with God behind their backs.
Zipper is a convenient mechanism that emerges in clothing, shoes, bags and other products. If after all the parts have waterproof skills, but the zipper does not, it is also a fall short, so the zipper does not admit defeat, and adds a new skill to himself, GET!
Waterproof zipper is a kind of nylon zipper, which is specially processed nylon zipper. The special treatment of waterproof zipper includes: attaching PVC, attaching TPU film, soaking in waterproof agent, coating waterproof zipper. Among them, TPU film waterproof zipper is a high-end product of waterproof zipper.
TPU waterproof zipper was born in the 1990s. Because TPU waterproof zipper is cold-resistant to -40°C, high temperature resistant to 100°C, waterproof, breathable, low temperature resistant, and flexible, it has been praised by customers at home and abroad. The performance of the coated waterproof zipper is: no shedding, no whitening, no embrittlement, low temperature resistance -70°C, environmental protection, softness, and good waterproofness.
All of PVC can be widely used for two reasons: one is the unique properties of PVC (rainproof, fire-resistant, antistatic, easy to form), and the other is the low investment and high output of PVC. PVC waterproof zipper formally utilizes the waterproof characteristics of PVC.
TPU is a highly environmentally friendly molecular polymer, and its Chinese name is thermoplastic polyurethane, also known as waterproof and moisture-permeable membrane. It is a major breakthrough in the application of new environmentally friendly materials to waterproof and breathable fabrics. It overcomes many shortcomings of PVC waterproof zippers. It not only has most of the characteristics of rubber and ordinary plastics, but also has excellent physical and chemical properties, so it is also called the future material. TPU film is a film made of TPU pellets through a special process. It inherits the excellent properties of TPU and has a wide range of applications. Because TPU overcomes many defects of PVC, TPU waterproof zipper is also superior in performance than PVC waterproof zipper. Waterproof zippers can play a waterproof function when it rains or encounter rain, and
waterproof zippers are also used for seamless products.

Next, let us further understand what is a good nylon waterproof zipper:
✔ The waterproof zipper film does not tear.
✔The degree of smoothness. It is generally believed that the better the smoothness of the zipper, the better the quality of the waterproof zipper. This is not the case. The smoothness of the waterproof zipper has certain index requirements. Anything that meets this index is a high-quality product.
✔The surface of the waterproof zipper film is flat and delicate, with a smooth feel similar to leather. This is the appearance of high-quality waterproof zipper.
✔ The color difference of colored waterproof zipper should be small. The difference between the color of the zipper tape and the fabric is the color difference. The color difference between the film surface color and the tape surface color is controlled within 5%.
✔In addition to the color difference, pay attention to the color fastness of the waterproof zipper. Whether the color fastness of the zipper reaches the standard grade and whether there will be color shift between the zipper and the clothing will directly affect the quality of the waterproof zipper product.
✔Waterproof effect: The size of the center seam is directly related to the waterproof effect of the waterproof zipper. If it is too large, it will obviously not have the waterproof effect and lose the meaning of the waterproof zipper itself.
✔Service life, the quality of the glue film attached to the waterproof zipper is directly related to the service life of the waterproof zipper.
