  • the high- 5 7/34 HS. 157 TS; ]9/.32,.64 twisted bundle may be heat set before or after the grinding or cutting action, or not at all.
  • This invention relates to the production of staple fiber structures.
  • a bundle of endless filaments which has been subjected to usual temporary high-twisting, preferably by means of a false-twist device, and to heat setting in the high-twisted state is brought, when. in high-twisted state, into frictional contact with grinding or cutting means (hereinafter referred to as grinding means) and thereby converted into a staple fiber structure.
  • Apparatus suitable for execution of the process of the present invention consists of at least one each filament delivery device, heating element, false-twist imparter and wind-up device, and is characterized in that grinding or cutting means are provided in the false-twisting path before or after the heating element for heat-setting the false-twist.
  • a further possibility is characterized in that the filament bundles are temporarily high-twisted by means of a false-twist device and are brought into frictional contact with the grinding means without heat-setting of the false-twist.
  • FIG. 1 is a schematic view of an apparatus for effecting the process of the present invention
  • FIG. 2 is a detail of FIG. 1 at an enlarged scale
  • F IG. 3 is a detail view of another form of the apparatus of FIG. 1 in longitudinal section;
  • FIGS. 4 and 5 are views similar to FIG. 1, but illustrating the grinding means in different attitudes relatively to the advancing filament bundle.
  • the filament bundle l 1 drawn off from delivery bobbin 1 successively passes through a thread-brake 2, a delivery device 3, 3', a heating element 4, a grinding or cutting device 10, a false-twist imparter 7, a second delivery device 8, 8' and finally reaches a winding-up shaft 9 by means of which the staple fiber structure 12 is wound up.
  • Means (10), capable of grinding or cutting fibers comprises two thread-guides, 5, 5', the purpose of which consists in braking the filament balloon caused by the false-twist imparter and to stabilize the direction of the filament bundle l l, and a rotating disc 6, the rim of which may be coated with a grinding agent such, for example, as carborundum, or provided with cutting ribs, serves to form the staple fibers.
  • the disc 6 may rotate in the same or the'opposite direction with respect to the direction of filament movement, a difference between the circumferential speed of the rotating disc 6 and the speed of the filament bundle 11 being necessary.
  • the circumferential speed of disc 6 should be preferably higher than the speed of the filament bundle 11 and, for example, it may amount to between 5 and 10 times the speed of the filament bundle.
  • the length of the contact path of the filament bundle 11 with the disc 6 and the pressure on the disc 6 can be selected by providing for modification of the mutual positions of the'disc 6 and the thread-guides 5, 5'.
  • Exchangeable, different grinding or cutting discs with various sizes of grinding grains or cutting ribs may be used according to the titer of the filament bundle or filaments.
  • vice 10 may also be provided upstream from the heating element 4.
  • a twist tube 13 may be used instead of a special grindingor cutting device.
  • a false-twist imparter consisting of a forked head 14 with a pin 15 of hard material such as, for example, sapphire passing across the fork gap.
  • an annular collar 16 which may be provided with a coating or grinding agent or with cutting ribs or edges or similar means. The filament bundle 11 from the heating element 4 enters into the twist tube at an angle so as to pass over and in contact with the collar 16, and then over pin 15 around which it has been looped.
  • the structure for advancing the bundle is similar to that of FIG. 1 and similar reference numerals identify similar elements.
  • the grinding means 10 is arranged so that the axis of rotation of the cutting wheel or disc 6 extends obliquely with respect to the filament path; and in FIG. 5, the grinding means 10 is arranged so that the axis of rotation of the wheel or disc 6 extends parallel to the direction of filament, movement.
  • This initial twist may be in filament bundles of a total titer of more than 150 dtex, approximately between 100 and 300 turns per meter and, in filament bundles with a total titer of less than 150 dtex, between approximately 200 and 400 turns per meter.
  • the process of the present invention is suitable for the treatment of filament bundles of synthetic material such as polyamides, polyesters, materials on a vinylic base (polyacrylonitrile) or polyolefines.
  • filament bundles of cellulose acetate it is also possible to use filament bundles of cellulose acetate.
  • two staple fiber structures may be ply-twisted. Furthermore, the staple fiber structures, after passage through the second delivery mechanism 8, 8 and before being wound-up at reduced tension, may be passed through a second heating element 17, also under reduced tension (which is shown in P16. 1 by a dashed line), whereby its elasticity is reduced.
  • the process of the present invention also makes it possible to produce mixed spun yarns from crimped synthetic staple fibers with natural staple fibers such as wool and cotton. It is preferable then to submit a filament bundle of synthetic material having a relatively coarse titer to the false-twist texturing treatment and to the grinding or cutting treatment, and to use the thusobtained staple fiber structure as roving for mixing with the natural fibers.

The filament bundle passes over the surface of grinding disc 6 rotating oppositely with respect to the direction of filament movement over a contact path 20 mm long, the circumferential speed of the grinding disc being between 400 and 600 m/minute. Finally, two temporarily high-twisted filament bundles are ply-twisted with 300 t/m in z direction.
