Filtration
Madaline®, offers a unique filtration media for multiple applications due to its unique structure which provides a filtration efficiency similar to meltblown while maintaining the strength of a spunbond continuous fiber.
Madaline® uses patented bi-component technology to produce a unique continuous filament web of polyester and polyamide fibers which is subsequently subjected to high pressure water jets to fibrillate, entangle and consolidated into a fabric. The fabric produced consists of both large and very small microfibers fibers intermingled throughout the web. Madaline® microfilaments are up to 100 times thinner than the human hair and are the key to Madaline®’s unique properties.
The table below compares Madaline® to spunbond and meltblown fabrics, each at the same unit weight and tested by the same procedure and rate of air flow. It can be observed that Madaline can certainly be considered a viable replacement for meltblown fabrics in some applications.
Madaline® can be produced up to 200 gsm at fabric widths up to 3000mm. It offers excellent spot-to-spot uniformity for heightened reliability, and its continuous filaments mean reduced fiber migration, freedom from lint and provides added strength.
It is also possible to adjust the ratio of polyester to nylon fibers and the degree of fibrillation (number of small fibers) in Madaline® for very specific customer requirements.
Madaline® can be combined in custom filtration composites with other nonwovens by thermal, adhesive or sonic bonding and by mechanical means. It can also be made into pocket filters replacing needlefelts in some applications. Madaline contains no binders or solvents and the ingredients for Madaline are in compliance with Regulation (EC) No 1935/2004 on materials and articles intended to come into contact with food.
