JX Nippon ANCI, headquartered in Kennesaw, GA, with manufacturing in Roanoke, AL, and composite manufacturing in Dalton, GA, has begun production of JX-CFF, (continuous fiber filtration), a polyester nonwoven which is much more uniform than conventional roll goods of spunbond and can be customized for pore size requirements, according to the company.

JX-CFF is a 100% continuous fiber polyester product which is made by using a propriety technology of thermally bonding specific combinations of various polyesters to accurately control pore size and tensile properties to specific customer specifications. Materials for JX-CFF may include the following nominal fiber sizes:

• Conventional Spunbond Polyester: 5 dpf (23 microns)
• Milife Microfiber Polyester: 1 dpf (10 microns)
• Milife Ultra-Microfiber: 0.07 dpf (2.7 microns)

Using various combinations of the above fibers along with proprietary bonding conditions, while varying unit weights, allows JX Nippon to customize web properties over a wide range to meet customer requirements. For example, the pore size of JX-CFF products can range from 10 to 100 microns. Additionally, web properties can further be influenced by the sequence of layering the various fiber sizes in JX-CFF.

Alternate versions of JX-CFF may include the following pending customer requirements: JX Nippon’s CLAF (PP or PE enhanced netting) which can aid in dirt/dust release; multiple films for unique properties; and other nonwovens such as spunlace, meltblown, bicomponent, and nano products.
