The article discusses air quality standards for dust from agricultural, combustion, and road traffic sources within the context of nonwoven fabric air filtration products from companies including Hollingsworth & Vose, Kimberly-Clark, and TWE.

The article offers information on the 12th Symposium on Textile Filters organized by Sächsisches Textilforschungsinstitut e.V. (STFI) that was held in Chemnitz, Germany. INSET: GLOSSARY NONWOVENS.

The article discusses the use of nonwoven fabric materials as filter media for various wet and dry applications. The author describes the integration of physical properties including hydrophobicity, antimicrobial activity, and high surface area into fibers used in filter media as well as offering charts of the sales of various sorts of nonwoven filtration materials.

The article describes the research done on the chemical stability of fibers which can be used for filtration systems to reduce the fine dust produced by biomass incineration. After tests of the chemical stability of fibers were conducted, preferred materials were selected for filtration tests. The article reports the results showing that most test materials did not reach the target values of gas dust concentration, but they did point to possibilities to improve these matters.

The article discusses the filtration market in regard to the nonwoven fabrics industry as a niche market with a positive outlook for the future, especially in the area of innovation. The author describes the filtration market exhibiting small and steady growth between 2007 and 2012, due to the fact that clean ambient air is an increasing demand for health, environmental, and safety needs of consumers. Also discussed is the design of filter media.

The article focuses on the use of the pile-fibre stitch-bonded Kunit fabric for the Hycoknit® regeneratable air filter medium. It mentions that regeneratable particulate air filters are recommended for use once the conventional particulate air filter gets overloaded. It notes that the combination of the Kunit fabric with a fine-pored random web can yield high dust storage capacity with good separation characteristics for very fine particles. It discusses an experiment on the filter materials over 25 operating cycles.

The article focuses on Hycofil, a type of hydroentangled nonwoven multiple layered filter media. The principle of hydroentanglement is discussed, as well as the web bonding process by water jets or spunlace technology. The patent pending routine upon which the Hycofil material is processed is also described.

Investigations have been carried out for cleaning of particulate air filters in the STFI and Institut für Luft- und Kältetechnik. The combination of stitch bonding and hydroentangling is an economically alternative manufacturing process of regenerative particulate air filter media. [ABSTRACT FROM AUTHOR]

Sila-Coat is a general term for water-based sol-gel solutions, developed by AIMT, formerly AHC-Oberfläichentechnik. In addition to the primary target to improve the corrosion resistance of oxide ceramic surfaces by sealing the pores, the process may also be used for the finishing of textile fabrics. [ABSTRACT FROM AUTHOR]

This article describes how the production of multilayer fiber-stitch-bonded fabrics featuring a density gradient is carried out. Multilayer fiber-stitch-bonded fabrics are extremely interesting for use in a wide range of technical applications, but until now, it has not been possible to produce them on an industrial scale. One of the most innovative techniques being used in the field of nonwovens bonding is hydrodynamic bonding, and the process can be used to produce a wide range of different combinations.

The article offers information on the development of high performance filter media for the reduction of air pollution particles. It cites the alternative surface filter media for Polytetrafluoroethylene (PTFE) membrane, which include needle-punched nonwovens and meltblown nonwovens. It mentions the characteristics of high-quality filter media, including excellent surface resistance, reduced operation costs, and high efficiency with very low clean-gas dust concentration.
