Hollytex

Description

[Ahlstrom Advanced Filtration] A registered trademark for a fabric series made with white, nonwoven fibers, with options available using either polyester fibers or polyethylene fibers. Hollytex® is spunbonded from continuous filaments resulting in a strong, lint-free, lightweight fabric with no added binders or pigments. It is calendared to produce a very smooth surface. Hollytex® is porous, but non-reactive, allowing moisture, vapors and liquids to pass through while effectively blocking particles. It is used as a support material, release paper, filtering agent, and interleaving paper. It is also used as a backing material for the 2-layer GORE-TEX® laminate.
