Microfibre was introduced in the late 1980’s. The definition of a microfibre is a fibre with less than 1 decitex per filament, 1 decitex is 9/10 of a denier about 1/16th the diameter of a human hair. The fibres can be combined to create yarn which can be then be knitted or woven into a variety of constructions. Microfibre wipes can be made using 100% polyester fine filaments or split fibres that are a blend of polyester and nylon.
This split structure gives the wipe the ability to pick up particles even when dry and can easily remove residues often without solvent. The increased surface area of a microfibre allows it to collect and hold dust, dirt and particles more effectively than rounded fabrics such as cotton. Virgin wipes are very soft so won't scratch surfaces. Care should be taken when reusing microfibre wipes, however, as particles can get stuck in the fibres which can then damage sensitive surfaces.
Microfibre has a high sorptive capacity around 6 to 8 times its own weight in water. The fast wicking ability means a wipe can remove spills quickly and easily, so it is very suitable for mopping as well as dry applications.
Contec has a range of microfibre wipes to choose from, 100% polyester standard fibre/microfibre blend, laundered in a Class 4 cleanroom with very low levels of fibres and particles, an 80% polyester / 20% nylon split microfibre and a unique cost-effective microfibre solution which has microfibre polyester yarn stitched into a polypropylene substrate.
