Cotton is a natural cellulose polymer fiber derived from the seed pods of cotton plants, characterized by its fibrous structure and relatively low density. It is widely used in textiles, apparel, and composite reinforcement due to its comfort, breathability, and biodegradability, though it offers lower strength and stiffness compared to synthetic fibers like polyester or glass-reinforced polymers. Engineers select cotton primarily for applications prioritizing sustainability, moisture management, and skin contact comfort rather than high-performance structural demands.
