What is Fully drawn yarns (FDY) ?
FDY also know as FOY is a type of highly drawn polyester filament yarns that can be used to produce high-strength fabrics and textiles. The fabrics and textiles made from bright FDY have a bright luster. FDY is typically used to produce fabrics and textiles for high-end undergarments, high-end sportswear and sports shoes, and home furnishings. FOY/ FDY is produced by a process similar to POY manufacturing except that the yarn is produced at even higher spinning speeds coupled with intermediate drawing integrated in the process itself FDY can be used directly in weaving and knitting, especially for warp weaving.
Polyester Partially oriented yarns (Polyester POY)
POY is a type of partially drawn polyester filament yarns, which is the primary form of polyester filament yarns directly made through polymerizing and spinning processes. It is primarily used as a main raw material for DTY.
Our POY is primarily used by us as raw materials for the production of DTY through twisting and partially used directly in weaving and knitting. . To the extent our POY was not consumed by our DTY production capacity, it had been sold separately as end products.
Draw textured yarns (DTY)
DTY is a type of polyester filament yarns produced by processing POY through a texturing process. This process disperses, curls, and entangles the filaments composing the POY yarn, which gives DTY a fluffy appearance and gives it the properties of both natural fiber and synthetic fiber. DTY is typically used to produce fabrics and textiles for high-end apparel, high-end sportswear, high-end sports shoes, high-end sports bags, home furnishings, and zipper tapes.
DTY is a finished product from POY, simultaneously twisted & drawn. It is widely used in knitting and weaving.
Draw Texturised Yarn (DTY) is manufactured by texturizing partially oriented yarn using texturizing machines. Polyester DTY yarn is a continuous filament yarn that has been processed to introduce durable crimps twists, interlaces, loops. Yarns made from thermoplastic materials can be textured by heat setting in a twisted condition, which results in polyester DTY yarn of greater bulk, higher stretch, and more pleasing aesthetics. DTY is available in semi-dull, Full Dull, and bright DTY finishes.

Polyester staple fiber (PSF)
PSF is a material formed by continuous or discontinuous threads, and it plays an important role in maintaining the tissue of animals or plants. Fiber is widely used as it can be weaved into threads, thrums, and or into the fibrous layer for paper or felt; and meanwhile, it is also used to produce other materials or formed into composite materials with other materials.
Polyester staple fiber is a short curly fiber suitable for mixing with cotton or other fibers such as rayon, acrylic, nylon, wool, ramie, etc. in spinning yarns for weaving and knitting. It is also an essential component for non-woven products and filling. Through spinning, weaving, knitting, and various non-woven processes, staple fiber can be transformed into the varietal textile and non-textile products commonly used in our daily life.
PTA
PTA has the form of a white, crystalline powder and looks like powdered sugar. It is quite inert, which means that, for example, it is difficult to dissolve in water or other liquids. PTA is an aromatic acid, primarily applied in the production of polyester. The main raw material for PTA is paraxylene (PX).
PTA is the down-stream product of petroleum. Light gasoline (also known as “petroleum naphtha”) can be produced from the petroleum through a certain process, MX (Mixed Xylene) can be extracted from petroleum naphtha, and then PX (paraxylene) is extracted. With PX (accounting for 65%-67% in the formula) as raw material and acetic acid as solvent, PTA produces crude terephthalic acid by air oxidation (with 35%-33% oxygen) under the action of the catalyst. Then, crude terephthalic acid is hydroformed to remove the impurities, then crystallized, separated, and dried to form pure terephthalic acid products, namely finished PTA products. Synthetic Resin.
Polyester chips (PET chips)
Polyester chip is the raw material used in the production of polyester fiber, filament yarn, and other polyester products.
PET (polyethylene terephthalate) chips are produced by granulating polyester formed in a polycondensation reaction of pure terephthalic acid and mono ethylene glycol. They are manufactured for textile applications and are supplied to the yarn-producing industry in semi-dull and super-bright.
The balancing stream of the polymer melt from the polycondensation section is discharged through metering pumps to the casting head. The molten ribbons coming out of the casting head are taken on the cooling chambers of the chips cutter where the molten ribbons are cooled by a chilled DM water system. The solidified polymer ribbons are then cut in a chips cutter and dried in the dryer. The dried chips are then passed through the classifier. The properly cut chips are stored in a chips silo. The chips are conveyed to the bagging silo for bagging.
What is Polyester Chip?
Polyester chips are made by mixing TEREPHTHALIC ACID and ETHYLENE GLYCOL, which are the main materials, at a certain ratio.
Polyester chips are made by melting the above two materials to make POLYMER, then drying and cutting them again.
When polyester chips are melted, Polyester filament yarns and short fibers are made.
For Textile Grade
PET Chips used in Textile Industry are also known as Fibre grade PET chips, filament-grade PET chips, or textile-grade PET chips. Textile grade PET Chips are used for making Polyester Filament yarn like POY, FDY, and Staple fiber used widely in the Textile industry.
The Yarn grade or Textile grade chips are available in Super Bright (BR Chips), Semi Dull (SD Chips), Cationic Semi Dull, and Cationic Super Bright PET Chips (CD Chips). The process of making PET Chips consists of mixing a thermoplastic polyester-resin material with an alumina tri-hydrate (ATH) filler and with a pigment, if desired, in a heated extruder to produce a continuous stream of the thermoplastic agglomerate. This product is allowed to cool, then it is cut, ground, and screened to a predetermined size, as required to meet the size characteristics of the desired resin-chip product.
PET Chips used in Textile Industry are also known as Fibre grade PET chips, filament-grade PET chips, or textile-grade PET chips. Textile grade PET Chips are used for making Polyester Filament yarn like POY, FDY, and Staple fiber used widely in the Textile industry.
They have the following characteristics :
- High Reaction Speed – low thermal degradation, bright whiteness, resistance to yellowing and deterioration.
- High Degree of Polymerization – high crystalline regions, concentrated molecular weight distribution.
