microfibre

Microfibre, or microfiber, denotes a fibre finer than one denier, typically a synthetic fibre with a very small diameter. The term is commonly used for fibres made of polymer materials such as polyester, nylon, or blends, which are processed into fabrics, mops, and cleaning cloths.

Manufacture involves extruding polymers to form filaments that are then drawn and sometimes split or etched to increase surface area. The resulting fibres can be woven or knitted into fabrics, or bonded to nonwovens for quality cleaning cloths.

Key properties include a high surface-area-to-weight ratio, softness, and strong absorbency, enabling lint-free cleaning and efficient filtration. Because of their fineness, fibre fabrics are typically very lightweight and durable, with good wicking and static control.

Common applications include microfibre cleaning cloths and mop heads, sportswear, upholstery, and automotive interior fabrics. Fibres are also used in filtration membranes, insulation, and composite materials due to their fine structure and network formation.

Environmental considerations: microfibres shed during washing and contribute to microplastic pollution in waterways. They are difficult to biodegrade and can accumulate in ecosystems. Reducing shedding and release is an area of ongoing research.

Care and maintenance guidelines: wash microfibre items separately or with similar fabrics; use mild detergents; avoid fabric softeners and high-temperature washing; tumble dry on low or air-dry to maintain absorbency.
