Poy Yarn

The production of it involves several key steps:

Polymerization: The process begins with the creation of polymer chips from polyester resins. These chips are heated and melted to form a thick, viscous liquid.

Extrusion: The molten polymer is forced through tiny holes in a spinneret, creating continuous filaments. These filaments are then cooled and solidified.

Drawing: Unlike some other synthetic yarns, it is only partially oriented during the manufacturing process. The filaments are stretched to a limited extent, which increases their alignment and strength compared to the precursor material.

Winding: The partially oriented filaments are wound onto bobbins or spools, forming it.

It has several noteworthy characteristics:

Softness: It typically has a soft and smooth texture, making it comfortable for various textile applications.

Uniformity: It is known for its consistent diameter and strength along its length.

Versatility: It serves as a versatile starting point for further processing into other yarn types, such as FDY (Fully Drawn Yarn) or DTY (Draw Textured Yarn), depending on the desired properties.

Colorability: It can be easily dyed to achieve vibrant and lasting colors.

Low Shrinkage: It has relatively low shrinkage properties, which can be advantageous for maintaining the size and shape of textile products.

Durability and Strength

Polyester yarn is highly durable and abrasion-resistant, making it ideal for reinforcing high-stress areas in socks, such as the heel and toe.

Moisture Wicking and Breathability

Polyester yarn is known for its moisture-wicking properties, making it an excellent choice for the inner lining of socks.

Colorfastness and Vibrancy

Polyester yarn holds dye exceptionally well, resulting in socks with vivid and long-lasting colors. 

 

1. What is POY yarn?
It stands for Partially Oriented Yarn, and it is a type of synthetic yarn used in the textile industry. It is primarily made from polyester, although other polymers can be used as well.

2. What is the production process for it?
It is produced through a process called partial orientation, where the polymer is heated and extruded through a spinneret. The resulting yarn is then wound on a bobbin and sent for further processing.

3. What are the applications of it in the textile industry?
It is used as an intermediate product in the production of different types of yarn and fabrics, such as textured yarn, filament yarn, and woven fabrics. It is also used in the production of industrial fabrics, such as conveyor belts and airbags.
