POY yarn stands for Partially Oriented Yarn. It is a type of polyester yarn that undergoes a process where the yarn is partially drawn but not fully oriented. This means that while it has undergone some stretching and alignment, it has not been drawn to its maximum potential strength and density.
POY yarn stands for Partially Oriented Yarn. It is a type of polyester yarn that undergoes a process where the yarn is partially drawn but not fully oriented. This means that while it has undergone some stretching and alignment, it has not been drawn to its maximum potential strength and density.
The manufacturing process of POY yarn involves melting polyester chips and extruding them into filaments. These filaments are then partially drawn to give them a certain level of strength and orientation but are left at a lower level than fully drawn yarn. The yarn is then wound into bobbins and is typically used as a precursor to other types of yarn or fabrics.
Key Characteristics of POY Yarn:
Partially Drawn: As the name suggests, POY yarn is only partially stretched and oriented.
Low Strength: It has relatively low tensile strength compared to FDY.
High Elasticity: POY yarn has more elasticity, making it suitable for applications where flexibility is required.
Versatility: It can be further processed into FDY yarn or textured yarn (DTY yarn) through additional drawing or texturizing processes.
Uses of POY Yarn:
Textured Yarns: POY yarn is often used as a precursor for making DTY (Drawn Textured Yarn), which is widely used in fabrics for apparel and home textiles.
Industrial Fabrics: POY is also used in industrial applications where a combination of strength and elasticity is required.
Knitted Fabrics: It can be used in the production of knitted fabrics, where its elasticity and low strength provide the required flexibility.
