The material of nylon zippers is nylon

The material composition of nylon zippers is primarily determined by several key components:

1.The Code Assembly Formed by the Weft Tape and Tooth Chain

The main body consists of a weft tape, which is woven into a single-sided tape using yarn on a weft-knitting machine. The tooth chain is then molded by a forming machine, stitched together, dyed, and ironed flat to form rolls of code assemblies that can be used to produce zippers in strip form. This is the weft tape we see.

2.The Slider Component

Most nylon zippers we see daily come with sliders, which are an indispensable part of strip zippers. Sliders can be made from various materials, including plastic, zinc alloy, and even needle-detection-friendly copper cores. Some are also made of stainless steel. Different materials and requirements will determine the price of the strip zipper.

3.Front and Rear Stops (or Upper and Lower Stops)

Front and rear stops, also known as upper and lower stops, are required in most strip zippers. Some are made of zinc alloy, while others use plastic for the front stop.

Many industries choose to use nylon zippers due to their affordable price and simple production process. A production line can cost between tens of thousands to hundreds of thousands of yuan, and with manual loading and unloading, products can be produced stably over the long term. We only need to ensure the quality of the machines to guarantee the quality of the finished products, which contributes to their widespread use. Of course, the quality of the finished products is also related to the raw materials, so we need to control every detail to produce quality that satisfies our customers.

Especially in densely populated places like schools, the air in classrooms is often very polluted. As the weather gradually turns colder, people tend to keep doors and windows closed for warmth, which leads to a decline in air quality. This is particularly true in densely populated places like schools, where the air in classrooms is often very polluted.
