oz yd 2 the solvent used was trichlorofluoromethane and the polymer was polyethylene the flow rate of the spin solution was maintained at about 150 lb hr in this example a 12 mesh screen fabricated from 314 stainless steel was positioned in the pressure let down chamber of the standard apparatus and process of u s pat no 3 227 794 anderson et al a swath analysis was performed to indicate the number of ropes within the resulting nonwoven sheet as a comparison a 2 0 oz yd 2 nonwoven sheet was also produced using the standard process of anderson et al except without the aid of the applicant 39 s inventive screen swath widths were about the same for both sheets the comparison sheet is characterized as the 34 prior art sheet 34 the results are summarized in table i as follows table i______________________________________type of rope inventive sheet prior art sheet______________________________________none or small 48 40medium 0 11heavy 0 0folds 0 16______________________________________ example 1 was repeated except that a 3 3 oz yd 2 nonwoven sheet was made with and without the benefit of the applicant 39 s inventive screen the results are summarized in table ii and generally indicate that ropes and folds are not as prevalent in higher basis weight sheets table ii______________________________________type of rope inventive sheet prior art sheet______________________________________none or small 12 10medium 3 5heavy 0 1folds 0 2______________________________________ the swaths made from the inventive apparatus appeared to be finer and freer from defects than the swaths made from the prior art comparisons but there was a slight tendency for more split webs to be produced however the split webs appeared to be of good quality the split was only.
