Raincoats are typically made primarily of polyester (polyester fiber), and may also include PVC or other waterproof coatings. Here's a detailed analysis:
Polyester (Polyester Fiber): As the base fabric, polyester offers high strength, abrasion resistance, and quick-drying properties. Its 150D/150D high-density yarn weave (e.g., a 3422 warp count) effectively blocks rainwater penetration.
Waterproofing: Waterproofing is achieved through lamination techniques (e.g., PVC coating or PU film lamination). A thickness of 0.38mm balances lightweightness and protection. Some products will indicate a hydrostatic pressure rating (e.g., ≥3000mm) to quantify their waterproofness.
Functional Extensions: Flame retardant treatment is achieved through the addition of flame retardants, complying with industrial safety standards such as EN11612. A weight of 472g indicates a medium-heavy weight suitable for multi-season use.
Environmental Performance: Some high-end products utilize a solvent-free lamination process to reduce VOC emissions.
