SILK
                                                Silk is a natural fibre primarily
                                                obtained from silkworms. It is
                                                lightweight, strong, and has high
                                                tensile strength. Silk is durable
                                                and can stretch up to 30% of
                                                its length without breaking,
                                                making it suitable for small-
                                                diameter ropes or ribbons.
                                                Silkworm larvae secrete the
                                                protein fibres as they spin their
                                                cocoons. The chain length of
                                                the proteins determines the
                                                material properties of the silk,
                                                with shorter lengths resulting in
                                                more robust fabrics and longer
                                                chains producing more flexible
                                                but weaker fabrics.







                                                POLYESTER
                                                Polyester is a synthetic
                                                fibre derived from coal
                                                and petroleum products.
                                                Its production contributes
                                                to high levels of carbon
                                                dioxide pollution. Polyester’s
                                                popularity is due to its cost-
                                                effectiveness, durability, and
                                                comfort in clothing, carpets, and
                                                upholstery fabrics. It is also used
                                                in plastic bottles, adhesives, and
                                                food packaging.







                                                NYLON
                                                Nylon is one of the most
                                                popular synthetic fabrics today.
                                                Developed by DuPont in 1935
                                                for industrial use, nylon is known
                                                for its strength and versatility.
                                                It has been used in various
                                                applications, from parachutes
                                                during World War II to lingerie
                                                and high-athletic wear. Nylon’s
                                                low melting point allows it to be
                                                fused with other materials, such
                                                as Kevlar or rubber, creating
                                                stronger products like tyres and
                                                gas tanks.
