• Wipes that are used in the personal hygiene sector such as facial tissues, cosmetic pads, baby wipes, personal hygiene and household and industrial wipes are mostly used in aqueous medium and require good wettability with polar liquids.
• hydrophilic fibers such as cellulose fibers, such as viscose or pulp, or their combination with polyester or polypropylene, are mostly used for the production of wipes.
• the web formation takes place via an airlaid or carding process with subsequent chemical, thermal or mechanical bonding.
• These so-called staple fiber webs often have insufficient abrasion resistance. Acceptable abrasion resistance must be paid for with pure staple fiber webs with a reduced sensor technology. It is therefore desirable to produce nonwovens which were either produced exclusively from a spunbonded nonwoven or which have a composite structure in which at least one layer consists of a spunbonded nonwoven.
• Spunbonded nonwovens are generally made of thermoplastics (polyesters, polyolefins) produced. These can be obtained without the addition of hydrophilic additives due to the insufficient water absorption of the pure polymers are not used for wipes, where absorption of hydrophilic substances or aqueous emulsions is desired ..
