Abstract (en)

[origin: US2016160393A1] A monofilament is particularly suited for use as a component in a spiral fabric. The monofilament is formed from a resin composition including a thermoplastic polymer. The thermoplastic polymer has an average molecular weight of less than 14200 g/mol. Alternatively, the monofilament is formed from a resin composition including a thermoplastic polymer, the thermoplastic polymer having a free thermal shrinkage of less than 1%. According to yet another embodiment, the monofilament is formed from a resin composition including a thermoplastic polymer, the thermoplastic polymer having an intrinsic viscosity of less than 0.72 dl/g. Yet alternatively, the monofilament is formed from a resin composition including a thermoplastic polymer, the thermoplastic polymer having a melt viscosity of less than 3000 P.
