How to tell between resin zipper and nylon zipper?

Which is better, nylon zipper or plastic zipper? Resin zipper is a kind of zipper. The teeth of the zipper are made of polyester plastic through dye color matching and discharged through an injection molding machine. The nylon zipper is composed of nylon monofilament wrapped around the center line through a heating die. So what is the difference between resin zipper and nylon zipper? There are some differences between the two zipper materials, production methods, scope of application and physical indicators. Let’s take a closer look at the difference between resin zipper and nylon zipper.

Definition of nylon zipper and resin zipper

1. Resin zipper

Resin zipper is a kind of zipper. The teeth are colored with polyester plastic through dyes and discharged through zipper injection molding machine. Resin zipper can be used in various occasions, but it is generally preferred to be used on clothing pockets. Resin zipper is based on copolymerized formaldehyde, and the cost is between nylon zipper and metal zipper. This type of zipper has better durability than metal zipper and nylon zipper. Commonly used zipper heads are painted, and sometimes electroplated.

2. Nylon zipper

Nylon zipper is a kind of zipper, which is composed of nylon monofilament wound by zipper heating and pressing mold. Compared with metal zippers and resin zippers, nylon zippers have the characteristics of low cost, large output and high penetration rate.

Nylon zippers can be used in various occasions, but generally prefer to be used in sportswear, shoes, bedding, bags, and tents. The material of nylon zipper is mainly polyester, the cost is relatively low, and it is also a kind of zipper that the market prefers.

The difference between resin zipper and nylon zipper

1. Material distinction:

Nylon zipper is made of polyester fiber material, whether the cloth belt, the teeth, and the suture are all polyester fiber. Resin zipper is injection molded after pelletizing plastic.

2. Production method:

Nylon zippers are made of thick polyester filaments that are spirally formed. The teeth and cloth belts are stitched together by stitches. Plastic zippers are made of polyester material particles that are melted at a high temperature, and then the rice teeth are injected onto the cloth belt by an injection molding machine to become a zipper slider and puller.

3. Differences in scope of application and physical indicators:

The nylon zipper has a tight mesh, soft and high strength. It can withstand bending more than 90 degrees without affecting its strength. It is generally used in luggage, tents, parachutes and other occasions that can withstand strong tension and often bend. Very high, wear-resistant, and widely used. Plastic resin zippers are smoother, and are generally used in occasions where strength and bending requirements are not too high.
