| Introduction | Polyester (English: Polyester) is a type of polymer containing ester functional groups on its main chain. Although there are many main types of polyester, the term "polyester" usually refers to polyethylene terephthalate (PET). |
| features | polyester fiber is often combined with other natural fibers to show the characteristics of both. cotton-polyester clothing has the advantages of toughness, anti-wrinkle and tear resistance, and is not easy to shrink than cotton clothing. Polyester fiber has poor air permeability, which makes moisture not easy to dissipate. Polyester fiber can be ignited by touching the flame. The fiber is curled and melted into beads and drips. When burning, it produces black smoke and has an aromatic smell. The ashes are black hard particles. |
| Preparation | Polyesters can be divided into two categories: "saturated polyester" and "unsaturated polyester", usually made of one or more polyacids (acid anhydride) and one or more polyols. |
| use | woven polyester or polyester fiber is widely used in daily life, such as trousers, hats, coats, bed sheets, computer mouse pads, etc. Industrial polyester materials such as some fibers, ropes and ropes, as well as conveyor belt fabrics, safety belts, coated fabrics, etc. Polyester fiber is also used for furniture filling, filling pillows, etc. Polyester fibers are not easily dyed by stains, and the only dye that can be used to change the fabric of polyester fibers is disperse dyes. |
