1. Absorbent and Drying: Bath Skirt uses pure cotton fabric. Cotton fibers have excellent moisture absorption, quickly absorbing moisture from the skin after bathing, keeping the body dry and providing a comfortable feel against the skin.
2. Breathable and Moisture-proof: The porous structure of pure cotton allows air to circulate freely, helping moisture evaporate and preventing stuffiness caused by trapped moisture.
3. Does Not Have a Complete Waterproof Layer: Based on the product description, Bath Skirt focuses on "absorption and warmth," without adding a waterproof film or coating to the fabric. Therefore, it is not a waterproof product in the traditional sense, but rather achieves "moisture-proof" through absorption and wicking away sweat.
4. Suitable Scenarios: Suitable for home use, especially in environments where free movement and warmth are needed after bathing; in outdoor or humid environments requiring waterproofing, a waterproof cover or other protective measures are still necessary.
1. Surface Polyurethane (PU) or Thermoplastic Polyurethane (TPU) Coating
A thin layer of PU/TPU is sprayed onto the surface of the cotton fabric, forming a continuous waterproof membrane while maintaining a certain degree of softness.
2. Film Lamination Process
A waterproof film (such as polyethylene or polyester film) is laminated to the cotton fabric using hot pressing or adhesives to form a "double-layer structure." The outer layer is waterproof, while the inner layer retains its water-absorbing and heat-retaining functions.
3. Waterproofing Agent Impregnation Treatment
The cotton fibers are impregnated with fluorinated or silane-based water-repellent agents, forming hydrophobic groups on the fiber surface, improving waterproof performance without significantly affecting the feel.
4. Composite Structure Design
A microporous waterproof layer (such as a polyurethane microporous membrane) is added to the back of the fabric. The front side maintains the moisture absorption of pure cotton, while the back side prevents water penetration, achieving a dual effect of "waterproof + moisture absorption."
