What is ATY Technology?

Update:2023 26,Apr

ATY, short for air textured yarn, is a type of synthetic yarn that offers the same cotton like feel as spun yarns. These yarns are produced by mechanical processes that use a cold air stream to bulked fibers. They have a similar touch and warmth as spun yarns and are recognized by specialists and ecologists as a truly green product.

What is ATY Technology?

The air jet texturising process enables millions of loops that make ATY yarns bulkier than DTY yet offering whole new dimension for carpet and fashion industry. This is a revolutionary technology that can offer a unique, fresh look and a completely different hand feel to any fabric.

In the Air Jet process, the end filaments of POY are overfed to a special jet that blows depending on the amount of overfeed, the individual filaments of each yarn into a string of smaller and larger loops. This is similar to the process of tangling of yarns, but it results in much better stability.

ATY YARN processing route: Creel 1, drafting zone 1 relaxation zone 1. Drafting zone offers the ability to create a variety of textures and effects, as well as a range of functions including a number of slubs.

Relaxing zone – a controlled relaxation of the fibers allows a more fluid flow through the system. This increases the flexibility of the final product and also reduces the risk of a duffing effect.

Deformation area – deformation of the ATY fibers produces a series of twisted ribs that give the finished fabric an appearance and feel more akin to natural fibres. The resulting fibers are woven, knitted, or bonded into a variety of fabrics.

Stabilizing area – a setting heater located in the stabilizing zone heats and stabilizes the yarn, thereby reducing the risk of duffing. This also reduces the size of the loops and makes the end product more stable for further processing.

For polyester ATY a heated pin, godet or plate is used in the drawing zone, some nylon ATY can be drawn cold. A good quality and durable ATY is made by a combination of high overfeed to the jet, low overfeed to the drawing zone as well as a suitable loop frequency. Smaller loops are more stable and provide a better volume than larger loops.
