Mahlo in the media
Due to its versatile properties, nonwoven is used today in countless industries for numerous purposes. The production of non woven fabric is a complex and costly process in which quality control plays a special role.
Depending on the requirements, staple fibre nonwoven, meltblown nonwoven, spunbonded nonwoven or wetlaid nonwoven is used for web formation. After web formation, the non woven web is bonded by thermal, chemical or mechanical processes. Mechanical web bonding produces, for example, needlepunched nonwoven and hydroentangled nonwovens
A final process step is nonwoven finishing, in which the non woven material is given special properties such as flame retardant, hydrophilic or oil repellent.
Non woven web is used for a wide variety of applications. A large field of application is hygiene and cleaning products. These include, for example, diapers, interlinings, wet wipes, microfibre cloths or vacuum cleaner bags made out of non woven web. Medical products such as surgical drapes and gowns, mouth-nose protection masks, dressings or plasters are also made of nonwoven.
Non woven materials are also very often found in technical applications such as geotextiles for drainage layers or erosion protection. Nonwoven filters, insulations and decorative components in the automotive sector, prepregs for transformers or battery separators are also included. This list for non woven applications could be continued endlessly.
