1. Field of the Invention
The present invention relates to a method of producing copolyester material with peptide, particularly to a method of producing improved copolyester material with peptide which has excellent hydrophilic, antistaticity, toughness and chemical resistance.
2. Description of the Related Art
Polyethylene Terephthalate (PET) is a widely used copolyester material. PET can be used to spun into fibers for weaving, making clothes, bedding, curtains, sheets and carpets, and can be extruded into films such as photographic film, tapes, videotapes and packaging materials as well. PET can also be blown into a vial, used to replace the glass container to fill tea, soft drinks or fruit juice and other beverages.
Taiwan is originally a major producer of Polyethylene Terephthalate (PET). Over the past decades, as the technology is getting mature and labor is expensive, manufacturers gradually shift production equipment to the mainland China and Southeast Asia, using cheap labor in these areas for mass production, and even selling back the products to the domestic. This results in widespread market competition and unprofitable dilemma.
Accordingly, it is necessary to develop an improved copolyester material having a property better than Polyethylene Terephthalate (PET), such that manufacturers can produce more durable and more competitive products.
