摘要

The effect of thermomechanical treatment modes on the mechanical properties of nonwoven needle-punched fabrics based on blends of bicomponent fibers with a linear density of 0.44 tex and polyethylene terephthalate fibers of 0.33 and 0.66 tex in a 30/70 ratio was studied. Materials produced by treating a fabric based on a blend of bicomponent and polyethylene terephthalate fibers of 0.33 tex showed a significant increase in the effective modulus reflecting tensile resistance at a roller temperature above 200°C and a treatment speed of <8 m/min. The effective modulus of materials obtained by treating a fabric based on a blend of bicomponent and polyethylene terephthalate fibers of linear density 0.66 tex monotonically increased with an increase in the roller temperature and a decrease in the treatment speed.
