Fabric in rubber hoses acts as reinforcement, providing strength, flexibility, and pressure resistance. Common materials include polyester, nylon, aramid (Kevlar), and cotton, chosen based on application needs. Polyester offers strength, stability, and low cost for general uses. Nylon provides abrasion resistance and flexibility for high-pressure hoses. Aramid delivers exceptional strength and heat resistance for extreme conditions. Cotton is softer and compatible with natural rubber, suitable for low-pressure or specialty hoses. Fabric layers are embedded between rubber during manufacturing, allowing the hose to withstand internal pressure while remaining flexible. Multiple plies or fabric–steel combinations enhance durability and safety.
