Everything You Need to Know About Polyester Threads

Polyester is utilised in various products, such as clothing, ropes, carpets, wall coverings, pillows, curtains, and sheets. This polymer can be divided into various types and is often used in the production of polyester thread, which is a versatile option for sewing a variety of fabrics and garments.

Currently, polyester threads are available in an extensive range of sizes, colours, types, and thicknesses to meet diverse manufacturing requirements. They recover fast after extension and absorb minimal moisture. These types of thread are also heat-resistant, chemical-resistant, and colourfast, so they can withstand most cleaning solvents. If you’re considering using them for your projects, here are the basics you need to know:

Core spun polyester

Core spun threads are made by combining filament polyester core thread with spun polyester. They are also called poly-core spun-poly, PC/SP, or P/P and are known for their strength, thanks to the filament core. This makes core spun polyester thread ideal for making quilts because it delivers a matte finish and optimum tensile strength.

Filament polyester

Filament thread is a continuous thread of polyester fibre. It can be a monofilament thread (which resembles a fishing line) or a multi-filament thread (which has two or three twisted strands resulting in a lint-free, smooth, and non-transparent material).

Spun polyester

Spun polyester threads are created by spinning or twisting shorter fibres, much like the cotton thread is made. These short fibres are twisted together to form a thread of a particular size. The resulting thread has a cotton-like appearance but is more elastic. As it is cheaper to produce, manufacturers are able to offer it at a lower cost to consumers. However, it is not as strong as other types of polyester thread and is therefore not suitable for quilting.

Trilobal

Trilobal polyester thread is a continuous, high-sheen, twisted multifilament fibre with the vibrancy of silk or rayon but with the benefits of polyester. Its triangular fibres reflect light and add an eye-catching sparkle to the fabric.

Bonded polyester

Bonded polyester is suitable for upholstery, automotive, and outdoor furnishing applications. Manufacturers apply a special resin coating to reduce friction and increase strength.
