Partially Oriented Yarn (POY)
is a type of polyester yarn that undergoes a partial orientation process during its manufacturing. It is produced by melt-spinning polyester chips or flakes, which are derived from purified terephthalic acid (PTA) and monoethylene glycol (MEG).
Partial Orientation: POY is created by spinning polyester chips at a high temperature, which results in the formation of continuous filaments. These filaments are then subjected to a stretching process to partially orient the polymer chains. The partial orientation gives the yarn some mechanical strength and stability.
Polyester Composition: POY is predominantly made of polyester, a synthetic polymer known for its excellent strength, durability, and resistance to stretching, shrinking, and wrinkles. Polyester also has good moisture-wicking properties and dries quickly.
Low Crystallinity: Compared to fully oriented yarn (FOY) or fully drawn yarn (FDY), POY has a lower level of crystallinity due to its partial orientation. This lower crystallinity gives POY a softer texture and improved dyeability, making it suitable for a wide range of color options.
Diverse Applications: POY is used in various industries and applications, including textiles, apparel, home furnishings, and industrial applications. It is commonly used for weaving, knitting, and warp-knitting processes to produce fabrics for clothing, upholstery, bed linens, curtains, and more.
Textile Processing: POY serves as a starting material for further processing into other yarn forms, such as fully drawn yarn (FDY) or textured yarn. These subsequent processing steps include drawing, heat setting, and texturizing to enhance the yarn's properties, appearance, and texture for specific applications.
Versatility: POY can be manufactured in different denier (thickness) and filament counts to meet specific requirements. It offers versatility in terms of yarn strength, softness, and color options, making it adaptable to various fabric types and end uses.
Easy Care: Fabrics made from POY tend to have good wrinkle resistance, shape retention, and ease of care. They are often machine washable, quick drying, and require minimal ironing, making them suitable for everyday clothing and household textiles.
