80% Polyester 20% Spandex Stretch Mesh 145gsm — 55210 Open Knit for Athletic Wear Sports Bras & Training Tops Manufacturer | China Weijin

145gsm polyester spandex stretch mesh. 55210 open knit. It's lightweight — pick it up and you feel the airiness right away. The fabric has an open, breathable structure with even mesh holes across the surface. The hand feel is dry and clean, typical of polyester, with a slight crispness from the open knit construction. The 20% spandex gives it real grip — stretch it and it snaps back into place. Not floppy, not stiff. It moves with the body and stays where you put it.

It holds up well for a lightweight stretch mesh. Polyester gives it good UV resistance and color stability — won't fade quickly even with frequent washing. The 20% spandex means the recovery stays strong wash after wash. Won't shrink much. Dries fast — the open structure lets air move through. The mesh openings are stable and won't stretch out of shape over time. It's not built for heavy abrasion, but for activewear panels and performance apparel, it lasts.

Sports bras and crop tops — the stretch and breathability make it a solid choice for fitted athletic tops. The mesh keeps air moving during workouts.

Training tops and jerseys — used as panels on backs, sides, and underarms where ventilation matters.

Leggings and bike shorts — accent panels that add stretch and breathability to high-movement areas.

Dancewear — leotards, bodysuits, rehearsal wear. The stretch gives good range of motion.

Apparel lining — quick-dry lining for performance outerwear, jackets, and bags.

1. What kind of mesh is this?

It's an open knit polyester spandex stretch mesh with uniform holes throughout. The 55210 specification refers to the yarn and knit construction. It's designed for activewear applications where breathability and stretch are both needed.

2. Is this see-through?

Yes — it's an open mesh with visible holes. It's made for ventilation and breathability, not full coverage. Use it as a panel, insert, or lining layer. If you need full coverage, put a solid fabric underneath or choose one of our solid stretch knits.

3. How does the 20% spandex feel in a fabric this light?

It gives the fabric a firm, supportive stretch. Despite being lightweight and open, the mesh has good grip and snap-back. It won't sag or bag out after wear. The combination of light weight and high recovery is what makes it useful for activewear.

4. Can I wash and dry this fabric normally?

Yes. Machine wash cold, gentle cycle. Do not bleach. Hang dry or low tumble. Cool iron if needed. The polyester dries fast — hang it up and it's ready in a couple of hours.
