Introduction to the main types of polyester thread

Corespun polyester threads is a combination of filament polyester core thread wound in polyester. It is also called "Poly-core spun-poly", "P/P" and "PC/SP" threads. The advantage of using core spun polyester thread such as OMNI or OMNI-V is that the filament core increases the strength. The matte finish and strong tensile strength of OMNI and OMNI-V make them a favorite for sewing.

Filament polyester is a continuous fiber thread. Some people hear the term filament and mistakenly think it is monofilament. The monofilament that looks like a fishing line is just one type of thin thread. It is a single (single) strand. MonoPoly is an example of monofilament thread. Other filaments are multiple filaments, consisting of two or three strands twisted together. This is the largest category of filament polyester. The multifilament strands are smooth and hairless, but opaque. The advantage of lint-free is that the machine is cleaner and less maintenance. The bottom line is really good! This is an example of this filament polyester thread.

Trilobite polyester is a multi-strand high-gloss continuous fiber thread. It has the bright appearance of rayon or silk, but has the advantages of polyester fiber. The triangular fibers reflect more light and add a charming luster to the textile. Our Magnifico and Fantastico threads are trilobal polyester threads.

Spun polyester threads is made by spinning or twisting short-length polyester fibers together. This is similar to how cotton thread is made. These short fibers are then twisted together to produce a thread of the desired size. Polyester staple fiber thread looks like cotton thread but is more elastic. Spun polyester is economical to produce and is usually a low-cost thread. We do not recommend using polyester spinning for stitching because it is not as strong as corespun, filament or trilobal polyester thread.

Bonded polyester fiber is a strong polyester thread used for furniture decoration. Because polyester has excellent UV resistance, bonded polyester is often used in outdoor furniture and automotive interiors. The special resin coating improves strength and helps reduce friction during high-speed stitching.

Polyester fibers recover quickly after being stretched (the term "stretching" describes stretching and recovery), and absorbs very little water. Polyester is heat resistant (safe for desiccant and iron) and has a melting temperature of about 480ºF (in contrast, nylon starts to yellow at 350ºF and melts at 415ºF). Polyester fiber is not fading, chemically resistant, and can be washed or dry-cleaned with the most common cleaning solvents.
