39 80 degrees g 39 60 degrees and h 39 0 0036 34 the spinnerets of fig1 and 2 are 0 015 34 in thickness using a spinneret plate having filament forming groups of apertures as shown in fig1 nylon 66 polymer was spun at a throughput of 50 kg hr position the filaments were quenched with cross flow air the filaments had a cross sectional configuration approximately the same as that shown in fig2 the filaments had a void content of about 15 fifty filaments were combined to form a yarn of 1000 dtex the yarn had a relative viscosity of 74 the yarns were bulked at 225 degrees c and had a bulk of 32 the yarn was formed into a single yarn velours style carpet and the carpet was tested for wear performance soil repellency hiding and cleanability glitter bulk cover and aesthetics the carpet passed all tests satisfactorily the carpet cleaned better than similar carpet made from yarns in which the fibers were of solid trilobal cross section using a spinneret place having filament forming groups of apertures as shown in fig3 nylon 66 polymer containing 0 30 titanium dioxide was spun at a throughput of 50 kg hr position the filaments were quenched with cross flow air the filaments had a cross sectional configuration approximately the same as shown in fig4 the filaments had a void content of about 12 fifty filaments were combined to.
