Abstract: A fabric is disclosed which is suitable for use in the manufacture of particulate filters for use in high heat environments having a high airflow requirement, together with a method for making the high heat filter fabric. The filter fabric has a sliver knit pile construction, and may be manufactured on conventional knitting machines. Both the yarn used in the backing of the high heat filter fabric and the fibers used for the pile of the high heat filter fabric are made of aramid materials, and the high heat filter fabric is suitable for use in high temperatures such as those associated with coal-fired power plants.

Abstract: A roll of knitted pile fabric is disclosed including an extended length fabric strip made from a plurality of seamed standard lengths of the fabric, the extended length fabric strip being substantially spirally wound upon a hollow core with consecutive windings of the extended length fabric strip being located close adjacent each other, and with consecutive rows of the extended length fabric strip overlaying each other on the hollow core. In the preferred embodiment, the standard length fabric strips are joined together at their respective contiguous ends using a small strip of heat-activated seaming tape. The extended length fabric strip is suitable for use in the manufacture of paint roller covers.
