Abstract
A paper machine clothing (PMC) fabric includes a plurality of monofilament yarns, at least some of which have a composition which is a thermoplastic resin. The thermoplastic resin yarns have physical properties including a water absorption of less than approximately 6% and a loop tenacity of greater than approximately 8.0 grams/denier.
Claims22
A paper machine clothing (PMC) fabric including a plurality of monofilament yarns, at least some of said yarns having a composition comprised of a thermoplastic resin, each of said yarns having physical properties including a water absorption of less than approximately 6% and a loop tenacity of greater than approximately 8.0 grams/denier.
A paper machine clothing (PMC) fabric yarn for use in a PMC fabric, said PMC yarn having a composition comprised of a thermoplastic resin, each of said yarns having physical properties including a water absorption of less than approximately 6% and a loop tenacity of greater than approximately 8.0 grams/denier.
A method of manufacturing a paper machine clothing (PMC) fabric yarn for use in a PMC fabric, said method comprising the steps of:
- extruding a polyamide 6/6T (PA6/6T) copolymer resin;
- spinning said PA6/6T copolymer resin into a filament;
- and
- drawing said filament into a monofilament PMC fabric yarn having physical properties including a water absorption of less than 6 percent (%) and a loop tenacity of greater than 8.0 grams per denier.
