1. Material differentiation:
Nylon zippers use polyester chips and polyester fiber materials, also known as polyester. The raw material for nylon zippers is nylon monofilament extracted from petroleum.
Resin zipper, also known as plastic steel zipper, is a zipper product mainly made of POM copolymer formaldehyde and injection molded by injection molding machine according to different product molds.
2. Production method:
Nylon zipper is made by threading nylon monofilament into a spiral shape, and then sewing the microphone teeth and fabric tape together with sutures.
Resin zipper is made by melting polyester material particles (POM copolymer formaldehyde) at high temperature and then injecting the teeth onto the fabric tape through an injection molding machine to form a zipper.
3、Differences in scope of application and physical indicators:
Nylon zipper has tight bite, soft and high strength, and can withstand bending of more than 90 degrees without affecting its strength. It is generally used in luggage, tents, parachutes and other places that can withstand strong tensile forces and are frequently bent. It has a high number of pull and close cycles, is wear-resistant, and has a wide range of applications.
Resin zippers are smoother and smoother, and are generally used in situations where strength and bending requirements are not too high. Resin zippers come in various specifications, different models, rich colors, and have a fashionable feel. They are commonly used on clothing jackets, down jackets, and backpacks.
4. Differences in the post-processing of chain teeth:
The post-treatment process of nylon chain teeth includes dyeing and electroplating. Dyeing can be done separately on the tape and chain teeth to dye different colors, or sewn together to dye the same color. Commonly used electroplating methods include gold and silver teeth, as well as some rainbow teeth, which require relatively high electroplating technology.
The post-treatment process of resin chain teeth is to color or film during hot melt and extrusion. The color can be adjusted according to the color of the tape or the electroplating color of the metal. The traditional film sticking process is to stick a layer of bright gold or silver on the chain teeth after production, and there are also some special film sticking methods that can be customized according to requirements.
