Is spun polyester good?

1. What is it?

Spun polyester is essentially "yarn made by cutting plastic into shorter pieces."
Regular polyester (long fiber) is like a single, smooth, and resilient plastic filament.
Spun polyester is like cutting plastic filaments into short segments and then spinning them into cotton-like yarn, mimicking the texture of cotton.

2. How is it produced?

Cutting: Cutting polyester filaments into short segments (about a few centimeters).
Combing: Straightening the short fibers like combing hair.
Twisting and spinning: Using a machine to twist the short fibers into yarn (similar to twisting hemp rope).

3. Feel and characteristics

Advantages:

Cotton-like feel: Softer than regular polyester, non-reflective, more like natural fabric.
Slightly better moisture absorption: Larger fiber gaps make it slightly more absorbent than regular polyester (but not as good as real cotton).
Less prone to snagging: The loose structure of the short fibers makes it less likely to come tangled after snagging.

Disadvantages:

Pilling Prone: After prolonged wear, the surface will develop pills (like sweater cuffs).
Not Durable: Areas subject to repeated friction (such as collar and elbows) are prone to thinning and tearing.

4. Common Uses

Low-Price Clothing: T-shirts, work uniforms (lower cost than cotton, looks like cotton).
Home Textiles: Pillow inserts, curtains (soft and wrinkle-resistant).
Filling: Dolls, sofa cushions (fluffy and lightweight).

5. Relationship with Recycled Polyester

Can be Used Together: Recycled polyester (made from recycled plastic bottles) can also be cut into short fibers to create "recycled short-fiber polyester."
Environmental Controversy: Although recycled materials are used, there is still a problem of microplastic shedding after washing, and the product has a short lifespan.
