Partially Oriented Yarn (POY)

In partially oriented yarn (POY), the crystalline domains of the polymer are partially oriented along the yarn or filament axis. However, crystalline domains are not fully oriented along the yarn axis in partially oriented yarn (POY). This partial orientation imparts sufficient strength to the as spun or just extruded yarns or filaments so that these can withstand the stresses of downstream processes to be converted into fabric. POY is the first form of yarn when a polymer is converted into a filament.

Manufacturing Process of POY

The manufacturing process of partially oriented yarn involves several steps to achieve the desired properties. Let's take a closer look at the key stages involved:
Polymer preparation
The process begins with the preparation of the polyester polymer, which is typically derived from petrochemical sources. The polymer is melted and extruded to form chips or pellets, which serve as the raw material for POY production.
Melt-spinning
The polyester chips are then fed into a melt-spinning machine, where they are melted and extruded through spinnerets to form continuous filaments. These filaments are rapidly cooled to solidify and stabilize them.
Drawing
The solidified filaments are then subjected to a drawing process, which involves stretching them to align the polymer chains and improve the strength and stability of the yarn. This stretching process imparts orientation to the filaments.
Annealing
After drawing, the filaments are annealed by heating them at a controlled temperature. This helps to relieve the internal stresses induced during the drawing process and further enhances the yarn's stability.
Partial orientation
In the final stage, the partially oriented filaments are wound onto bobbins or cones, resulting in partially oriented yarn. The degree of orientation achieved during this process determines the specific properties of the POY.

POY Yarn Recycling and Reuse

The process involves breaking down used POY textiles or waste materials into their basic components and then reusing them to create new POY yarns. Here's an overview of the POY recycling process:

Collection

The first step is to collect used POY textiles or waste materials from various sources, such as discarded clothing, industrial waste, or post-consumer waste.

WINDING AND PACKAGING

The recycled POY yarn is wound onto spools or bobbins and packaged for use in the textile industry.

Cleaning

The sorted POY materials are cleaned to remove any dirt, stains, or contaminants. This may involve washing, chemical treatments, or mechanical processes.

Shredding

The cleaned POY materials are shredded or cut into small pieces, which makes it easier to process them further.

Melting

The shredded POY materials are melted at high temperatures to break down the polymer chains. This process turns the POY into a molten state, which can be extruded or spun into new fibers.

Extrusion or spinning

The molten POY is extruded or spun through a spinneret, which forms it into new fibers. These fibers can then be cooled and solidified to create recycled POY yarn.

Drawing and texturing

The recycled POY fibers are drawn and textured to improve their strength, elasticity, and other properties. This process involves stretching the fibers and applying heat or other treatments to achieve the desired characteristics.

SORTING

The collected materials are sorted based on their composition and color. This step is crucial to ensure that the recycled POY yarn maintains its quality and properties.

Applications of POY Yarns

POY yarns are found across a spectrum of industries that include:

Textiles: POY yarns are used extensively in the production of textiles, including clothing, upholstery and bedding. The degree of twist in the yarn can affect the properties of the resulting textile, such as its strength, durability and drape.

Carpets and rugs: POY yarns are used in the production of carpets and rugs. The POY yarns help to create a dense, durable pile that can withstand foot traffic and wear and tear.

Rope and cordage: POY yarns are commonly used in the production of rope and cordage, where the degree of twist is important in determining the strength and durability of the final product.

Sewing and embroidery: POY yarns made from high-tenacity filament and fibre are used in sewing and embroidery, particularly for hand stitching. The POY construction of the yarn helps to prevent unravelling and tangling.

Crafts: POY yarns are popular for use in various crafts, such as knitting, crocheting and weaving. The degree of twist can affect the texture and appearance of the resulting project.

Medical textiles: POY yarns are used in medical textiles, such as sutures and bandages, where the strength and durability of the yarn are important.

Industrial textiles: POY yarns made from high-tenacity polyester, yarns are used in various industrial applications, such as filtration, insulation and reinforcement materials, where the properties of the yarn, such as strength, durability and chemical resistance, are important factors.

Benefits of POY

Lightweight
Partially oriented yarn is lightweight, making it ideal for applications that require lightweight textiles. The low density of POY enables the production of comfortable fabrics that are not bulky and do not add unnecessary weight.
Moisture-resistant and quick drying
Partially oriented yarn is moisture-resistant and quick-drying. It doesn't absorb moisture, which keeps fabrics dry and prevents them from getting waterlogged. Fabrics made from POY dry quickly after getting wet, ensuring a fast drying time and maintaining comfort for the wearer.
Resistance to wrinkling and shrinkage
Partially oriented yarn resists wrinkling and shrinkage, ensuring that textile products maintain their shape and appearance even with frequent use and washing. This property is highly desirable for applications that require wrinkle resistance and dimensional stability.
Color consistency
Partially oriented yarn provides consistent color throughout the yarn. Its smooth surface and uniform structure allow for even dye penetration, resulting in uniform color distribution. This property is crucial for applications that demand a consistent and uniform color appearance.
Longevity
Fabrics made from partially oriented yarn are highly durable and resistant to wear and tear. They can withstand frequent use and washing without losing their quality or appearance over time.

Problems and Remedies in the Winding of POY Packages

Ribbon formation
Ribbon formation is also called as patterning. Pattern will occur when winds per double traverse is a whole number for surface driven machines. In case of precision winders, when the ratio between rotational speed of package and traverse frequency are in an integral ratio which causes the subsequent to warp on the same point. When successive layers wrapped on the same point, it will lead to pattern formation. Even, there will be an abnormal sound at the time of ribboning, it can also be visualized with the help of stroboscope by matching the frequency of light with the rotational speed of the package.
Pattern formation can be avoided by use of ant patterning mechanism. In this mechanism, the rotational speed of the drum shall be interrupted, package may be momentarily lifted from the drum.
Yarn wrapping on the drum
Two drums i.E. Grooved drum and plain drum may get sticky deposits on their surfaces. It could be due to spin finish, monomers which cause yarn wraps on the drum. To avoid the yarn wrapping, both the drums should be regularly cleaned. Spin finish oil may also cause the deposits on the drum. It is suggested that silicon free water can be used while preparation of spin finish oil.
Yarn warps may also cause due to spin out, broken traverse guides, damaged paper tubes, improper spin finish oil preparation.
Crushed paper tubes
High tension in the yarn may leads to paper tube crushing. The reuse of paper can lead to also the same problem. Before reuse the condition of paper tube must be checked. The proper tension is to be adjusted in the yarn depending upon the winding speed and single yarn strength.
Winder vibrations
Winders must be checked for vibrations periodically and any excessive vibration should be removed and rebalanced by balancing machines.
Poor package build
The bad package build could be due to the tension variations in the all packages of the same winder. Equal tension must be adjusted by adjusting the pig tail guide.
Hardness of POY bobbins
When the winder pressures are not adequate, it may lead to hard packages. By the adjusting the over feed, it can be avoided.
Broken filament
BF may occur due to fault in the spinning. When few filaments present out of the spin finish applicator guide, would lead to bf. Also check the oil reaches properly to the tip of the guide. When any hole of spinneret blocked, spin out/bf will occur. In this case, change the pack. Scrapping of spinnerets will also reduce the chances of BF.
