Polyester Hot Melting Filament Yarn For Curtain

There are many different kinds of fabrics that can be made from polyester. Most commonly filament, Polyester Hot Melting Filament Yarn for Curtain consists of continuous fibers spun into a yarn-like material. Other types of polyester fabrics include staple, tow, and fiberfill.

Making a filament is done in much the same way as making cotton or wool yarns. The long filaments are fist cut into short pieces called staples and combined together to spin into a single yarn made up of thousands of small fibers.

When producing staple fiber, the polymerization and drying steps are similar to those for filament, but in the melt spinning step, the spinneret has more holes than in the case of filament yarn. These holes allow the thick, rope-like bundles of polyester to emerge from the spinneret as what are called tow.

Newly-formed tow is quickly cooled in cans that gather the thick fibers, then drawn on heated rollers to several lengths three or four times their original length. These fibers are used for a variety of products, including hoses, power belting, and ropes and nets.

Changing the shape of the spinneret can change the hand and strength of the finished polyester fiber, as well as the dye-ability of the yarn. Square, oval, and bean-shaped fibers are common, as are hollow fibers that add to the insulation properties of a polyester yarn.

Polyester also has good dimensional stability. This makes it ideal for hoses, power belting, and other industrial applications where it is needed to hold its shape at high temperatures. It is also resistant to stains, wrinkles, and chemicals.If you are interested in this Polyester Hot Melting Filament Yarn for Curtain, please feel free to contact us, we will reply you as soon as possible.
