The Basics of Polyester Filament Yarn

Polyester Filament Yarn (PFY) is a very popular choice for apparel makers. It has high tenacity, huge strength, and great shrinkage resistance. It is a very cost-effective material and is also lightweight.

It can be used for a variety of different applications, including apparel, home textiles, and even automotive fabrics. It is very soft and silky to the touch, and it also wicks away moisture.

There are two main types of polyester yarns: filament and spun. Both are created from the same material: a polymer called PET, which is made by the reaction of terephthalic acid and ethylene glycol. The first step in creating a polyester yarn is to group the single fibers together into filaments, and then twist or air-entanglement them so that they become workable.

The twisted and textured polyester filaments can be woven into a range of products, from lightweight garments and curtains to industrial fabrics and insulation materials. The filaments are available in a variety of diameters and lengths, and they can be produced to a wide range of elasticity levels.

Orientation and Texture: The type of polyester yarn that a fabric is made from has a great effect on the end product, and the texture can influence the elasticity, wearability, and aesthetics of the finished fabric. The most common orientation is straight, but some fibers are twisted or textured to produce softer and more versatile fabrics.

Dyeing Uniformity: The dyeing uniformity of textured polyester filament yarn is a key quality metric. It determines how well the fabric performs when it is exposed to a variety of dyeing solutions. This can be a crucial factor in determining whether the fabric will remain soft and supple or develop wrinkles.

Spun Yarn: PFY is typically spun into a yarn that contains thousands of short filaments. It is usually spun in a course that is higher than 16 tex counts, which is the standard for most knitted fabrics.

It can be spun into a variety of different types of fabrics, from cotton and wool blends to polyester blends and natural fibers like cotton and wool. This allows designers to produce a wide variety of fabrics, from t-shirts to dress pants and jackets.

Fully Drawn Yarn: Unlike twisted and textured yarns, fully drawn fibers are not deformed before being drawn out of the spinneret, and the fabric they are produced into has greater elasticity. They are primarily used for clothing and home textiles, such as denim, terry towels, and non-textured fabrics.

This type of polyester filament yarn is a preferred option for the production of upscale sportswear and undergarments, as it is capable of being knitted quickly, which helps to minimize the time necessary for design and manufacturing. It is also a good choice for producing non-textured fabrics, as it helps to ensure that the finished fabric has a consistent color and appearance.

The recycled polyester filament yarn market is expected to grow significantly over the next few years, as consumers seek environmentally friendly options for their apparel and home textile needs. The demand for a wide array of high-end, eco-friendly fabrics is driving the growth of this market.
