POLYESTER
Polyesters are fully synthetic fibers or fibers of linear macromolecules having in the chain at least 85 percent by weight of an ester of a diol and terephthalic acid. They are formed either by polycondensation of glycol with Dimenthylterephthalat with precipitation excess glycol (Terylene type) in the melt spinning process.
Polyester fibers are 100% wet-strength and have a high resistance to alkalis u. Acid resistance. They excel in their elastic properties, particularly its rapid resiliency, all other synthetic fibers. Opposite polyamides the low elongation is emphasized at low tensile stresses.
Usability
Polyester is versatile for all kinds of fabrics of ladies u. Clothes, men's, in the "classic mix" with 45% wool, and with shares of usually more than 50% in blends with cotton. As filament and staple fiber polyester is the dominant material for curtain fabrics. Because of their high resiliency Polyesterfiberfill is particularly suitable as a filler for quilts and padding.
Manufacturing
Organic terephthalic acid combines with ethylene glycol to diglycolterephthalate. Polyester is prepared in the melt spinning process. There are polyester filaments or staple fibers.
