Polyester Staple Fibers (PSF)

Polyester Staple Fibers

The largest Volume of Synthetic Fiber Products in the World is Made of Polyester Fiber or Polyester Staple Fiber (PSF). Polyester is a Type of Polymer That Has Ester Groups, Which mainly include Polyethylene Terephthalate (PET).

Other polyesters, such as polybutylene terephthalate (PBT) and polyethyl methyl terephthalate (PTT), are used in carpet fibers due to their superior fiber yield.

Polyester Staple Fibers are not elastic alone, but by combining with other fibers to achieve this ability. Cotton also breathes much better than polyester because it allows air to pass through the fibers. Polyester clothing is more resistant to moisture and wrinkles rather than cotton clothing

Advantages & Disadvantages of Polyester Staple Fiber

Advantages: Has a favorable range of physical properties, strong, light, paintable, wrinkle resistant, resistant to most chemicals, easy quick-was drying, resistant to stretch and shrinkage, resistive against Ultraviolet radiation, low absorption, cheap, mass production from petrochemical sources.

Disadvantages: Prepared from chemicals, long-term direct contact of polyester with the body, leads to serious problems such as skin allergies, skin cancer, lung and heart, due to non-breathable and insulating properties, causes the body to sweat more, flammability High, prone to static accumulation (static electricity), longer odor retention than natural fibers, poor fluff retention compared to carpet / rug nylon, less breathability rather than natural fibers.

Note: Of course, biodegradable polyesters from lactic acid, glycolic acid and other hydroxy acids do not cause contact problems with the body, even in medical devices such as soluble sutures.
