13 which is intersected roughly in the middle and at a right angle by the rectilinear portion 23 therewith the sizes of said portions and the ratios thereof are similar to the sizes of the like portions in the cross sections shown in fig8 12 formation of the filament through the spinneret with such a configuration of the holes is performed from molten polycaproamide having a relative viscosity of 2 72 and the temperature of 275 u00b0 c the temperature of the cooling air is 19 u00b0 c the air feed velocity is 33 m s the rate of forming is 3 500 m min the draw ratio is 2 6 and the temperature of the second stretch godets is 150 u00b0 c as a result of formation through such a hole the cross section of the filament as is shown in fig1 is composed of an element 34 g 34 shaped as a two pronged fork three rectilinear branches 24 25 and 19 and a ring shaped element 34 b 34 the ring shaped element 34 b 34 forms in the filament a cavity similar in size to that in the filament whose cross section is shown in fig9 and which is arranged circumferentially relative to the axis of symmetry of the contour at the same time the rectilinear branches 24 25 19 and the element shaped as a two pronged fork form together and along with the ring shaped element five deep open capillary channels and one less deep capillary channel formed by the branch 19 along with the element 34 b 34 due to the plurality of capillary channels and also due to the small cavity such a filament features high sorption properties and fine crimp and may be used in light fabrics and knitwear suitable.
