A fibrous, non-woven thermal insulation comprises synthetic polymeric resin microfibers, staple fibers and bonding fibers which are randomly oriented and randomly intermingled in a single layer. The microfibers comprise between 0% and 95% by weight virgin synthetic polymeric resin and between 5% and 100% by weight recycled polyethylene teraphthalate. In one embodiment the microfibers have an average diameter between 1 to 10 microns and comprise between 5% and 80% by weight of the insulation; the staple fibers have an average diameter between 10 and 30 microns and comprise between 5% and 90% by weight of the insulation; and the bonding fibers have an average diameter between 0.9 and 15 denier and comprise between 5% and 95% by weight of the insulation. The bonding fibers have thermoplastic surfaces with a lower temperature softening point than the microfibers and staple fibers and bond the fibers together to form the insulation material.

An air filtration media comprises a single layer of randomly oriented and randomly intermingled synthetic, polymeric resin microfibers, staple fibers and bonding fibers. The microfibers, taken as a whole, have an average fiber diameter no greater than 5 microns and comprise between 50% and 90% by weight of the filtration media; the staple fibers, taken as a whole, have an average fiber diameter between 10 and 30 microns and typically, comprise between 5% and 45% by weight of the filtration media; and the bonding fibers, taken as a whole, have an average fiber diameter between 0.9 and 15 denier and comprise between 5% and 25% by weight of the filtration media. The bonding fibers have thermoplastic surfaces with a lower temperature softening point than the microfibers and the staple fibers and bond the fibers together to form the air filtration media.

The microfibers comprise between 25% and 95% by weight virgin synthetic polymeric resin and between 5% and 75% by weight recycled polyethylene teraphthalate. The microfibers have an average diameter between 1 to 8 microns and comprise between 35% and 80% by weight of the insulation; the staple fibers have and average diameter between 10 and 30 microns and comprise between 15% and 60% by weight of the insulation; and the bonding fibers have an average diameter between 14 and 30 microns and comprise between 5% and 25% by weight of the insulation. The bonding fibers have thermoplastic surfaces with a lower temperature softening point than the microfibers and staple fibers and bond the fibers together to form the insulation material.
