07-06-2009 Finishing Treatments Applied to Nonwovens From Different Polymers |
|
| Nonwovens can be produced from any kind of fiber-forming polymers. Besides web formation and bonding technology, the type of polymer will to a large extent specify the properties of the nonwoven. Nonwovens made from cellulosic fibers will exhibit good hydrophilic properties, whereas nonwovens made from polypropylene are hydrophobic. | |

07-06-2009 Saving energy the old-fashioned way |
|
| Plants need dust control systems to help provide a safe environment for workers. While a dust control system doesn't usually provide a direct retum on your money, there are some things you can do to reduce the system's operating costs without sacrificing dust control performance. | |

07-06-2009 Filtration technology - Its impact upon our lives and the environment |
|
| In these times when globale warming poses such a challenge for this and future generations it is perhaps worth reflecting how advances in filtration technology have impacted upon our lives and the environment in a positive way. Not for the sake of complacency but to illustrate how we as engineers and scientists have made a real difference over the recent past and how we must re-double our efforts in the future. In this short paper the authorh as considered some examples of gas and liquid technology which impact upon our lives. | |
