Filament fibres having a practically unlimited or infinite length are called filaments. Filament fibres are continuous (long) fibre. It may be natural like silk or synthetic like Nylon. Filament fibres are measured in yards or meters.
Planned product obsolescence or built-in obsolescence, is an industrial design strategy of which; the intention is a proposed product with a limited lifespan. The most common form of product obsolescence is the fading out of product when new versions.
Textile waste can be classified as either pre-consumer or post-consumer textile waste. Pre-consumer textile waste is the leftovers or by-products from textile, fibre- or cotton industries. Post-consumer textile waste is the waste of fleece, flannel, corduroy, cotton, nylon, denim, wool, and linen.
Velvet is a fabric with a short, tightly woven pile, originally made of silk; it is today made of rayon, nylon, acrylic and cut pile fabrics.
Synthetic fibres are a term used on human-made treads. Chemicals combined into large molecules called polymers produce fibres like nylon, polyester, spandex, acrylic, modacrylic, olefin, saran, spandex, and vinyl.
Nylon fibre. It is a synthetic fibre invented by DuPont that was used originally for hosiery but in many applications. Nylon is naturally water-repellent, easy to dye, and very strong. These features have helped plastic replace cotton in many industrial uses, like bags and flags.
Man-made fibre. Viscose and Acetate, derived from cellulose, were almost all the human-made fibres in existence before World War II. During the 1930s, after intensive fibre research, several new synthetic fibres were produced which led to the production of nylon.
Low energy fibres. The most significant low energy fibre is recycling production.
