ABSTRACT:
A fabric is disclosed which is suitable for use in the manufacture of particulate filters for use in high heat environments, 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.
