The effect of smooth-roll thermal bonding on the tensile properties of blended cotton/polyester fiber webs was determined. Increases in calender roll temperatures from 408 degrees Kelvin to 436 degrees Kelvin raised tensile loading levels and energies-to-rupture sharply, whereas increasing calender roll pressure produced only small changes in these physical properties. Neither the thermal conditions nor the roll pressures greatly affected the extensibility of the nonwoven samples. Normalized specific stress levels were dependent on fabric weight; this was attributed primarily to dynamic heat transfer conditions in the calendered webs. 3 refs.
