5540 Polyester Spandex Black Swimwear Fabric 175gsm — Full Black纱 | Chlorine Resistant | Four-Way Stretch | 58 Inch
How does it feel?
175gsm polyester spandex black mesh swimwear fabric. Solid, but not heavy — 175gsm is the middle ground in swimwear. You pick it up and you know it's there, but it won't weigh you down in the water. The black is full and deep — not that faded, grayish black you get with cheap fabric. It's the kind of black that stays black, wash after wash. 13% elastane gives it a comfortable four-way stretch that moves with the body without feeling restrictive. 147cm wide. Completely opaque, no lining needed. If you want a fabric that looks clean, feels secure, and handles serious pool time without the bulk of a heavyweight, this is it.
Is it tough? Does it last?
Polyester at this weight is a chlorine-fighting machine. It resists degradation from pool chemicals better than nylon, holds its color through hundreds of hours of exposure, and won't turn brittle or thin out over time. The black stays black — it won't fade to gray or turn dull. The spandex recovery is solid — this fabric won't bag out, sag, or lose its shape after repeated wear and washing. For training suits and regular swimwear that get worn hard and washed often, it goes the distance. Not the kind that quits after one season.
What can I make with it?
Training swimwear, resort swimwear, one-pieces, bikinis. Good for swimmers who want a solid, reliable black fabric that handles chlorine without fading. The 175gsm weight is versatile enough for both active training and leisurely wear. If you need lighter and breezier for vacation pieces, we have 135gsm and 150gsm options. If you need maximum compression for competitive racing, we have 200gsm, 250gsm, and 320gsm. This one's for when you want that sweet spot — solid coverage, comfortable stretch, and a true black that lasts.
FAQ
1. Is this "full black纱" different from regular black swimwear fabric?
Yes. "Full black纱" means the yarn itself is fully dyed black, not just surface-dyed or printed. The result is a deeper, richer black that won't fade to gray or turn dull after washing. It's the difference between a black T-shirt that stays black and one that looks washed out after a few cycles. This one stays true.
2. How's the stretch compared to your higher-spandex options?
13% spandex gives it a comfortable, responsive stretch — enough to move with the body and recover its shape, but not the intense compression of performance race suits. It's the kind of stretch you want for regular training and resort wear: secure without being restrictive. If you need firm compression for competitive racing, we have options with 20% and 25% spandex.
3. Is this fully opaque? Do I need a lining?
Yes, fully opaque at 175gsm. No lining needed. You can use it for one-pieces and bikinis without worrying about transparency, even when wet. The full black纱 also helps with coverage — dark, dense, and reliable.
4. Polyester vs nylon for swimwear — why pick this one?
Chlorine resistance. Polyester naturally handles chlorine better than nylon. If your customer is a regular lap swimmer or training in a chlorinated pool several times a week, polyester will hold its color and structure longer than nylon. Nylon is softer and has a natural sheen. Polyester is the workhorse — drier, crispier, and built to last longer in harsh pool conditions. Plus, the full black on polyester holds especially well over time.
5. Will the black fade or turn gray?
No. The full black纱 construction means the yarn is dyed through, not just on the surface. It won't fade to gray, won't turn dull, won't lose its depth. Even after hundreds of hours in chlorinated water, the black stays black. Rinse with fresh water after each use and it'll last even longer.
6. 147cm wide — is that narrower than your other swimwear fabrics?
Yes, 147cm is slightly narrower than our standard 150–160cm swimwear fabrics. This is specific to the 5540 construction. For most swimwear applications, the width is workable — you'll just want to plan your cutting layout accordingly. The difference is small enough that most production runs won't feel it.
7. How does this compare to your 200gsm polyester swimwear fabric?
Weight and compression. The 200gsm is heavier with more structure — better for competitive suits and pieces that need stronger compression. This 175gsm is lighter and more flexible — better for regular training, resort wear, and everyday swimwear. If you want a bit more freedom of movement without sacrificing coverage, go 175gsm. If you want more compression and structure, go 200gsm.
8. Is this fabric suitable for medical or healthcare applications?
No. Our fabrics are designed and produced for swimwear, sportswear, and related uses. We do not currently manufacture or supply fabrics for medical, filtration, or industrial applications. If you need medical-grade textiles, we recommend consulting a specialist supplier.
