2 therefore the inventive finish applicators were readily placed in the last draw stage the yarn products after passing over the last heated roll set were dry this is a substantial advantage of the inventive method and a novel feature of the yarns so produced the data also demonstrate that the finish application by the inventive applicators can be controlled by the finish feed rate a 250 filament 1000 denier pet yarn was overfinished at 5400 m min using an u201c immersion applicator u201d similar to that described in example 1 but having two liquid fed chambers whose total length in the direction of yarn travel was 1 5 inches 3 81 cm the cross sectional area of the yarn entry openings fig1 yarn entry opening 5 and the area of the constricted passages fig1 constricted passages 6 of the u201c immersion applicator u201d were 0 0335 cm 2 no dimension of the yarn entry openings was greater than 5 5 times the effective diameter of the yarn the percent of the air boundary layer cross section that was blocked from entry into the finish applicator was at least 98 yarn finish contact pressure estimated from finite element numerical modeling was greater than 40 psi 276 kpa approximately 0 386 wt spin finish was applied by a kiss roll applicator at a speed of about 2800 meters per minute at the entrance to the draw panel the placement of the u201c immersion applicator u201d between heated godets was as described in example 1 the overfinish feed rate to the.
