There are many types of chemical fiber filaments. These include: UDY, MOY, HOY, POY, FOY, FDY, DTY, ATY, DY, etc. The four most widely used ones are POY,FDY, DTY and ATY.
POY
The full name is PRE-ORIENTED YARN or PARTIALLY ORIENTED YARN. It refers to the incompletely drawn chemical fiber filaments obtained by high-speed spinning with an orientation degree between unoriented yarns and drawn yarns. Compared with UDY, it has a certain degree of orientation and good stability, and is often used as a special yarn for DTY.
FDY
The full name is FULL DRAW YARN. Synthetic fiber filaments further produced by spinning and drawing. The fibers are fully stretched and can be used directly in textile warping processes. Conventional fully drawn yarns include polyester and nylon, both of which are chemical fiber filaments. FDY fabric feels smooth and soft and is often used to weave silk-like fabrics. It has a wide range of uses in clothing and home textiles.
DTY
The full name is DRAW TEXTURED YARN. It is made of POY as raw yarn, which is stretched and false-twisted. Often have a certain degree of elasticity and shrinkage.In addition to its high breaking strength and elastic modulus, excellent heat setting properties, good resilience, heat resistance, light resistance, strong corrosion resistance, easy washing and quick drying, DTY also has high bulking and heat insulation properties. It has the characteristics of good sex, comfortable hand feel, soft luster and so on.
DTY is an ideal raw material for knitting or weaving processing. It is suitable for making clothing fabrics (such as suits, shirts), bedding (such as quilt tops, bedspreads, mosquito nets) and decorative items (such as curtain fabrics, sofa cloths, wall coverings, car interiors). Decorative cloth) etc. Among them, fine denier yarn is more suitable for silk-like fabrics, while medium-thick denier yarn can be used for wool-like fabrics.
ATY
The full name is AIR TEXTURED YARN. The principle is to use air jet technology to intertwine the filament bundles to form irregular twisted filament loops, so that the filament bundles have fluffy terry-like yarns. The processed textured yarn has the properties of both filament and staple fiber yarns, with strong wooly feel, good hand feeling, and better coverage than staple fiber yarns.
ATY is suitable for woven and knitted. Using air texturing technology, it can be made into monofilament or multifilament of medium or fine filament, or core-covered imitation wool, imitation linen, imitation cotton, etc., which is called imitation yarn textured yarn. It can also be made into Processing of coarse fiber yarns for carpets, sofas, and tapestries.
ATY is superior to the raw silk before deformation in terms of fluffiness, breathability, gloss, softness, etc. The fineness is 10-15% higher than that of the original filament. The boiling water shrinkage remains at about 3%, but the strength decreases by 40%, because only a small part of the monofilament is stretched, but it bears the bearing capacity of the entire filament bundle.
