Which is better, acrylic yarn or polyester yarn (2)

The second difference between acrylic yarn and polyester yarn:

Polyester fabric: polyester fabric is a kind of chemical fiber clothing fabric used in daily life. Its advantages are good wrinkle resistance and shape retention.

1. Polyester fabric has high strength and elastic recovery ability. Therefore, it is firm and durable, wrinkle resistant and iron free.

2. Polyester fabric has poor hygroscopicity, which makes it stuffy and hot to wear. At the same time, it is easy to carry static electricity and dirt, which affects its beauty and comfort. However, it is easy to dry after washing, and the wet strength hardly decreases, and it does not deform, so it has good washing and wearing performance.

Polyester yarn: when it comes into contact with the flame, it will first cause curling and melting, and then burn. While burning, it will drop molten matter, with yellow bright flame and blue color. When burning, there is black smoke at the top of the flame, and the combustion will stop immediately after leaving the flame. After the combustion is stopped, it has a slightly aromatic smell, and the ashes are hard blocks in black glass, which can be crushed by fingers.

Acrylic yarn: when in contact with the flame, it melts first, and then burns slowly. There is a yellow flame and flash. It can continue to burn after leaving the fire, but the speed is slow. When burning, it emits a pungent smell, some like coal tar oil. The ashes are irregular black hard blocks, which are not easy to crush.
