Synthetic fiber material

These are polyester fibers, the most widely used type of synthetic fiber, and they are chemically stable. Because their molecules are hard and have high crystallization points, they have higher tenacity and lower elongation than natural fibers/materials. For those reasons, they are also widely used in organic solvents. Demand for our polyester fibers is constantly increasing thanks to their excellent productivity and compatibility with natural fibers. They can be used in various applications, from everyday essentials including yarn for textiles, fabric products, and packaging materials for beverages and food to industrial products such as tire cords.

Major Products

  • Terephthalic Acid (TPA)

    Commonly called terephthalic acid, TPA is a pure white powder whose main raw material is p-Xylene which is obtained by refining crude oil, and it is produced after the oxidation, refining, separation, and drying processes. Depending on the production process, TPA can be classified into three categories, purified terephthalic acid (PTA), qualified terephthalic acid (QTA), and medium TPA (MTA). TPA is chiefly used as the main raw material for polyester fiber, PET resin, film coatings, and engineering plastics. Because TPA has excellent levels of heat resistance, abrasion resistance, and insulation, techniques are being developed to allow it to be used in diverse applications including various types of bottles, electric and electronic goods, industrial materials, building materials, and machine components.

    Characteristics of TPA
    • PackagingSea-bulk, 1.1MT net in jumbo polypropylene bag with inner plastic bag
    • ApplicationsChips for fiber, chips for bottles, filament yarn, staple fiber, and plastic resin

  • PET Chips

    PET chips are the main raw material for PET bottles, PET film, and PET yarn. White, odorless, and variable, PET chips are made from PET resin, a liquid made by mixing terephthalic acid (TPA) with ethylene glycol (EG). PET resin turns into PET chips after being put through a series of solidification processes known as polymerization. PET chips are mainly used to manufacture containers for various types of products, including food and beverages. PET chips are a non-toxic, clean, sensible, and environmentally-friendly material and thus can replace glass, aluminum and other synthetic resins.

    Characteristics of PET Chips
    • Special Characteristics & StrengthsPET chips have high productivity and excellent processability and generate trace amounts of acetaldehyde (AA). For those reasons, they are suitable for food and beverage containers. Thanks to their high heat stability, PET chips do not cause yellowing. They also have excellent chemical resistance, transparency and mechanical properties.
    • ApplicationsBottles for fruit juices, ionic drinks (sports drinks), bottles for beverages and drinking water, and containers for cosmetics and hair treatment products Sheet extrusion: Film, blister packaging, and packaging of agricultural and building materials, and billboards

  • PSF

    Polyester materials such as high purity terephthalic acid (PTA) and ethylene glycol (EG) turn into gel type polymers through polymerization where they are subject to heat and pressure. The polymers then go through the spinning process where yarn is spun and the elongation process where various physical properties are given to them. Afterwards, they are cut into short pieces and made into cotton form, and this resulting product is called polyester stable fiber (PSF). PSF is widely used for clothing and for industrial purposes. PSF is used in cotton form as fillings for clothes, bedclothes, furniture and so on, and it is also used for spinning after being twisted into yarn. Furthermore, it is also made into non-woven fabrics by compression to be used for various industrial purposes including automobiles, buildings, and furniture, and sanitation and agricultural materials.

    Characteristics of PSF
    • Special Characteristics & StrengthsHighly resistant to stretching and shrinkage, as well as to most chemicals. Easily dyeable and washable. Highly resistant to wrinkles, abrasion, heat, and mold.
    • ApplicationsAll types of clothing Household goods: Carpets, curtains, sheets and pillow cases, wallpaper, and upholstery Other: Hoses, power belts, ropes and nets, threads, tire cords, sails, and fiber fillings (pillows and furniture)
