<p>Jersey or Tricot knitted material with >=50 wt% thermoplastic synthetic fibre (polyamide/polyester/polyolefin) is comprissed at 5-35 kg/cm2 esp. 10-25 kg/cm2, applied uniformly in the direction of the thickness dimension, for >=5 secs. at >90 degrees C but below m.pt. of the fibres until its original thickness is reduced to 55-95%. The resultant simulated weave has a porosity of is not >80% and a surface contour figure, on >=1 face, of is not >6. It is then heat fixed by decatizing at a pressure of is not 100 g/cm2 for is not >2 mins, at 100 degrees C using steam or 150-200 degrees C using hot air. Significantly cheaper than weaving.</p> |
