ABSTRACT:
A hybrid nonwoven liner for a diskete holder is bonded and impregnated with a small amount of binder which is uniformly distributed throughout the fabric and comprises no more than 5% by weight and preferably between 1.5-3.0% by weight of the fabric. The low concentration of binder ensures that the liner surface does not become totally coated with plastic film that reduces cleaning ability, while also providing a high increase in tensile strength and a significant debris reduction. The binder solution preferably has a high surface tension (low surfactant level), so that the binder beads and becomes dried at junction points of the fibers and evenly distributed throughout the fabric. The low level of surfactant ensures a low risk of chemical attack of the disk media surface.
