Nonwovens, due to their high surface area, cellulose content, and some of the manufacturing processes (such as hydroentangling), can carry a bio-burden that could tax the preservative in the cleaning solution of the ensuing wipe product. If the product needs to be preserved, attention should be paid to the nonwoven substrate as well as the solution.

Textiles, as a woven cloth or a nonwoven fabric, are probably the most common industrial filter medium, and are made from natural (cotton, silk, wool) and synthetic fibres. Wire cloths and meshes are also widely used in industrial filtrafions, produced by weaving monofilaments of ferrous or non-ferrous metals the simpler plain weave is used for sieving and sizing operations, and the more complex weaves such as Dutch twills are used on pressure and vacuum filters. At the small scale, particularly for laboratory use, filter papers are common, made from fibrous cellulosic materials, glass fibre or synthetic polymers these papers are made using developments from conventional paper manufacturing processes. 

Nonwoven Manufacturing. Cotton staple is readily processed to form carded, air laid, or carded/crossed-lapped webs that can be bonded by various techniques to form useful nonwoven materials, eg, needlepunched, spimlaced (hydroentangled), and stitch-bonded nonwovens, and resin-bonded and thermal-bonded carded fabrics (68). Many times a combination of these processes is used to produce hybrid structures and other products. Cotton s share of the nonwovens market in 2002 is 7.8% globally and 2.8% in North America (69). In 2000-2001, 32-36 million kg (70-80 million lb) of cotton was used in North America to... 

The basic concept employed in making a nonwoven fabric is to transform fiber-based materials into two-dimensional sheet structures with fabric-like properties. These are flexibility, porosity, and mechanical integrity. Their manufacturing processes can be split into four groups dry-laid webs, extrusion-formed webs, wet-laid webs, and web-bonding.
