Polyester Knitted Fabrics — Properties, Applications, and Care Guide

1. Understanding polyester knitted fabrics

Polyester knitted fabrics are made from synthetic polyester fibers formed into interlooped structures. Unlike woven textiles, knitted fabrics have greater stretch and flexibility, providing comfort and a smooth hand feel. They are widely used in garments, upholstery, and technical textiles due to their durability, wrinkle resistance, and low moisture absorption. The continuous filament yarns of polyester make the surface stable and resistant to shrinking after repeated washing.

These fabrics can be produced in circular or warp knitting machines, allowing for various surface textures and weights. Depending on the knitting structure and yarn type, the fabric can appear lightweight and breathable for sportswear or dense and warm for outerwear.

2. Key characteristics of polyester knitted fabrics

The properties of polyester knitted fabrics make them suitable for diverse functional and aesthetic needs. Below is a summary of their notable performance advantages.

• Excellent elasticity and recovery due to interlooped yarn structure, ideal for body-fitting garments.
• High wrinkle resistance and dimensional stability, maintaining shape after multiple uses.
• Quick-drying performance with low moisture absorption, suitable for sportswear and outdoor applications.
• Excellent colorfastness and resistance to UV degradation, keeping colors vibrant over time.
• Good abrasion resistance for high-activity wear and industrial usage.

3. Common knitting types and fabric structures

The knitting method directly influences the appearance, elasticity, and mechanical strength of polyester knitted fabrics. Below are the most common structures used in production.

Single jersey

Single jersey polyester fabric is lightweight, soft, and has a smooth face with a slightly textured back. It stretches mainly in the width direction, making it suitable for T-shirts, linings, and activewear. Its simple construction offers cost-effective manufacturing and good drape.

Double knit (interlock)

Interlock polyester fabric features two layers of loops that interconnect, producing a denser and more stable fabric. It has balanced stretch in both directions, excellent opacity, and resistance to curling, commonly used for dresses, uniforms, and thicker sportswear.

Rib knit

Rib knit fabrics consist of alternating knit and purl stitches that create vertical ridges. They offer superior elasticity, particularly for cuffs, collars, and waistbands, where form-fitting comfort and recovery are essential.

4. Applications of polyester knitted fabrics

Polyester knitted fabrics are valued for their versatility. They can be engineered for fashion, performance, or industrial applications. The table below summarizes typical end uses.

5. Maintenance and care tips

Proper care helps maintain the fabric’s elasticity, color, and softness. Polyester knitted fabrics are generally easy to wash, but correct handling extends their life.

• Wash in cold or warm water using mild detergent to avoid damaging fibers.
• Avoid bleach or high-alkaline detergents that may weaken the yarn structure.
• Tumble dry at low temperature or air dry flat to prevent distortion.
• Iron on a low setting if needed, using a pressing cloth to protect the surface finish.
• Store folded or rolled rather than hung for long periods to preserve shape.

6. Sustainable considerations

Modern polyester knitted fabrics increasingly use recycled PET yarns, reducing dependence on virgin petroleum resources. Manufacturers also adopt eco-dyeing and low-energy finishing processes to lower environmental impact. Recyclable polyester blends make it possible to create circular textile solutions without compromising performance.

Through continuous innovation in yarn technology and knitting design, polyester knitted fabrics continue to balance comfort, functionality, and sustainability, making them a vital material for modern textile production.
