nonwoven fabric finished by means of the softener was dried in an air dryer at an air temperature of 100 u00b0 c a nonwoven fabric comprising splittable fibers was obtained which had a weight of 115 g m 2 fig1 shows that very good i e distinct segmentation is present between the pet segments and pp segments of the spun splittable pet pp pie fibers despite the low weight proportion of polypropylene pp fig2 shows that after the segmented pet pp pie fibers are bonded slight presplitting of the spun splittable pet pp pie fibers of the nonwoven fabric is present as a result of the thermal bonding step a nonwoven fabric used as tuft backing was tufted as follows using a commercially available tuft yarn 1 10 u2033 division and velour finish in the carpet industry in particular the automotive sector stitch count 56 10 cm tuft yarn pa6 bcf 1300 dtex f128 tuft yarn weight 400 g m 2 the distance between the tufting needles which introduce the tuft yarn into the tuft backing in this case the nonwoven fabric tuft backing is expressed in fractions of an inch thus 1 10 u2033 means 10 needles per 2 54 cm i e a distance of 2 54 mm between the tufting needles the spacing of the stitches along the length of the tuft backing is referred to as the stitch length the number of stitches is expressed per 10 centimeters and also determines the number of loops or neps other tuft divisions for example 5 32 u2033 u215b u2033 5 64 u2033 1 16 u2033 or 1 22 u2033 may also be used for manufacturing the top layers of a carpet a commercially available pa6 bcf 1300 dtex f128 yarn.
