The major polyester in the market is polyethylene terephthalate (PET), an ester formed by step growth polymerization of terephthalic acid and the diol ethylene glycol. The polyester fibers all have similar properties, are highly resilient and resistant to wrinkling, possess high durabilily and dimensional stability, and are resistant to chemical and environmental attack(Needles, 1986). In 1996, 24.1 million metric tons of manmade fibres were produced globally. The main volume gain took place in production of PET fibres (PET filament 9%, PET staple 4%) (Froehlich, 1997). Dramatic growth in PET fibre production is foreseen in Asia in the near future (Harris, 1996). The cost of polyester, with the combination of its superior strength and resilience, is lower than that of rayon. Polyester fibres are hydrophobic which is suitable for lightweight facing fabrics used in disposable industry providing a perceptible dry feel on the facing, even when the inner absorbent media is fully saturated. As the new methods of PET processing and bonding of are developed, rayon is replaced by polyester on the market. 49% of the total nonwovens market share in USA belongs to polyester staple, reaching up to 291 million pounds in…
