Polyester (Non-Cellulosic Fiber)

• Polyester fibers are long chained polymers produced from elements derived from coal, air, water, and petroleum.

• The molten polymer is extruded through a spinneret, and filaments are drawn into the desired fiber.

• Depending on the profile of the spinneret, the filament can be hexagonal, octagonal, or even hollow.

• The continuous fiber can be used as a filament yarn by grouping and then twisting the fibers to them to make them thicker and stronger. A monofilament yarn has just one filament fiber which is usually not twisted.

• The continuous fiber can be cut into a staple length (standardized to 32 or 38 or 44 or 51mm) and then spun conventionally, quite like cotton. Polyester can also be spun with other fibers produce polyester-cotton (PC), poly-viscose (PV), poly-wool and poly-nylon blends.

•Heat-setting of polyester fabrics eliminates the internal tensions within the fiber generated during manufacturing, and fixes the fabrics in a relaxed state, and thus avoiding subsequent shrinkage or creasing of the fabric.

•Fabrics like 100% poly georgette are normally in filament yarn, while blends like PV or PC are invariably spun yarns.

•Denier is a measure of the thickness of a filament fiber or a yarn and is defined as the mass in grams per 9000 meters. Polyester fibers are normally 1.0, 1.2, 1.4, 2 and 3 denier.

^{Some Major Polyester Fiber Uses}

Carpets, curtains, draperies, sheets and pillow cases etc..are the home furnishing and all form of apparel.
