What exactly is air fiber?

Simply explain: The material commonly used in mattresses is called "air fiber" or "4D air fiber", and the industrial product name is "(transparent) spinneret ring" or "spinneret plate". Although this material is an ancient material with a history of over 60 years, its use on mattresses has a very short history (probably within three to five years, reportedly from Japan).

For a long time after it was manufactured, there was no suitable application scenario for its use until the 1970s and 1980s, when people found that it was a good floor mat placed at the door to remove mud on the sole of the shoe, and gradually promoted it.

This is a very mature industrial product that can be manufactured using various thermoplastic materials or directly using polyester materials. Due to its wide range of raw materials and low price, its use is becoming increasingly widespread.

The preferred TPE raw material for the "air fiber" used on mattresses (Thermoplastic Elastomer); Some manufacturers will use low prices for polyethylene (PE), a thermoplastic resin. The most common "air fiber" in our daily life uses PVC (polyvinyl chloride) as the raw material
