Fabric Definition:
Spectra is a brand of ultra-high molecular weight polyethylene (UHMWPE) fiber known for exceptional strength-to-weight ratio, cut resistance, and durability, used in ballistic protection, ropes, and industrial textiles.
Composition:
100% UHMWPE (Spectra), Spectra/Nylon, Spectra/Polyester, Spectra/Kevlar, Spectra/Glass composites, often with coatings
Texture:
Smooth, slightly waxy, high-luster, slippery, flexible, lightweight, strong, can be stiff in composites, matte or glossy
Stretch Level:
None to Low (no stretch; fiber is stiff; composites rigid)
Fabric Construction:
Woven (Plain, Twill, Satin), Unidirectional, Knitted (limited), Braided, Laminated
GSM Range:
100-500 GSM (light to heavy; 200-400 GSM for ballistic)
Breathability:
Low (dense, impermeable; breathable in woven form)
Moisture Management:
Very Low (hydrophobic, does not absorb water)
Durability:
Very High (extremely strong, cut-resistant, abrasion-resistant, long-lasting, resistant to chemicals)
Thermal Properties:
Moderate; low thermal conductivity, not insulating; performs well in cold environments
