  • the yarn 1 comprises loops 4 therein giving a very high bulk and fluffs 5 of relatively great length projecting out of the periphery thereof, which structure cannot be found in conventional spun yarns.
  • the method involves the step of feeding a substantially non-twisted strand of staple fibers such as a roving or sliver from a fiber supply zone to a fluid treatment zone where individual staple fibers are intertwined with each other by a turbulent flow of fluid to cohere thereby into a single yarn, at least some of said staple fibers to'be supplied to said fluid treatment zone have a length larger than the distance L between the grasping point in the fiber feed zone and the intertwining point in the fluid treatment zone.
  • intertwining point means herein the point at which the intertwinement of staple fibers most effectively occurs due to the turbulent flow in the fluid treatment zone.
  • the yarn of the present invention In order to manufacture the yarn of the present invention, it is insufficient merely to subject a conventional non-twist strand of staple fibers to normal fluid treatment, i.e. it is necessary to employ specific conditions for intertwining the staple fibers with each other to a considerable degree. It is, therefore, fundamentally required that the fluid exerts a strong intertwining action on the staple fibers and that at least some of the staple fibers have a length larger than the abovespecified distance.
  • FIG. 3 illustrates the principle of the method of the present invention.
  • a roving 7 unwound from a bobbin 6 is drawn, for example, approximately 20 times its original length while passing through back rollers 8, draft means 9, and front rollers 10, to become a non-twist strand in the form of fleece.
  • the fleecy strand is continuously supplied from the front rollers 10 to a fluid treatment apparatus 12 through an inlet tube 11.
  • High pressure fluid such as compressed air is introduced following the arrow through an inlet 13 into a disturbance chamber 14 and discharged through an outlet 15.
  • An aspirator effect is therefore produced on the inlet tube 11, whereby the fleecy strand is sucked into the disturbance chamber 14 and discharged therefrom through the outlet 15.
  • the individual staple fibers are actively intertwined with each other to form a single spun yarn 16 by the turbulent flow produced in the disturbance chamber 14 and the wide flow of fluid ejected through the outlet 15.
  • the spun yarn 16 so formed is continuously wound into a package 18 by way of a take-up roller 17.
  • the feed stock i.e. a strand of staple'fibers such as a roving or sliver should comprise staple fibers lying substantially parallel at least some of which have a length L larger than the distance L between the grasping point of the pair of front rollers and the outlet of the fluid treatment nozzle 14, i.e. the point at which the intertwinement due to the turbulent flow most effectively occurs.
  • the staple fiber when at least a substantial number of the staple fibers have a length L larger than the distance L, the staple fiber is still grasp ed between the pair of front rollers when the forward end thereof reaches the outlet and consequently, strongly intertwined with other staple fibers by the turbulent flow of the fluid to form thereby a continuous spun yarn.
  • the ratio of the staple fiber having length L contained in the strand should preferably be within a stated range, i.e. from 5 percent to 80 percent based on the total weight of the strand.
  • the fluid treatment apparatus where staple fibers are intertwined with each other to form a spun yarn of the present invention is not critical. Any type of fluid treating apparatus may be used as long as it is capable of exerting a sufficient intertwining action on the staple fibers. l n particular, those of the type equipped with a jet apparatus capable of producing a strong turbulent flow such as, for example, of the type provided with two or more jet apparatus whereby two or more flows of fluid are simultaneously introduced into the fluid treatment zone as illustrated later, are preferred. Some conventional apparatus used for the production of filament yarn of high bulk by employing a fluid ejection technique may be used if the fluid treatment conditions are strictly determined.
  • the fluid used in the present invention may be either gas or liquid. Compressed air is most preferable because of ready availability and no baneful effect on the human body or the apparatus, and particular protection apparatus is not required. Hot air or saturated steam or super-heated steam may be preferably used when thermoplastic staple fibers are treated. Pressure of the fluid flow may be optionally varied.
  • the ratio in peripheral speed of the front rollers as a fiber supply source to the take-up roller it may be varied depending upon the characteristic of staple fibers used, the material and form of staple fibers.
  • the ratio is usually 1:1. It is however preferred to adjust suitably the ratio depending upon the particular spinning condition when a smooth treatment cannot be effected at the fixed ratio of 1:1 in the case where staple fibers having no crimp or having conventional crimp are used.
  • the ratio may be varied in a manner such that some of the staple fibers are either strained or released during the treatment.
  • a deflecting member (not shown in FIG. 3) is so arranged in front of the outlet 15 that the member deflects the fluid flow passing out of the outlet and consequently produces a further turbulent flow and enhances the intertwining effect of staple fibers.
  • the distance between the deflecting member and the outlet may be suitably determined depending upon the desired spun yarn and the feed stock used.
  • the length of fluffs 5, i.e. end portions of the staple fibers projecting out from the periphery of the spun yarn may be varied by altering the distance L between the grasping point of the front rollers and the outlet of the fluid treatment nozzle or the ratio in diameter of the inlet tube Ill to the thickness of the fleecy strand. That is, the length of fluffs increases with an increase of the distance L and an increase of the ratio in diameter of 'the inlet tube to the thickness of the fleecy strand, and decreases with a decrease of these quantities.
  • the length of fluffs may also be varied by varying the shape of crimp, surface characteristic and physical characteristic of the staple fiber and the particular additives applied to the staple fiber.

Further, a turbulent flow occurs as the first fluid accompanied with the intertwined fibers runs against the wall of the slanting tube 22, and therefore, enhances the intertwining effect on the fibers. Therefore, this embodiment is obviously preferred to that shown in FIG. 5 in the case where both a strand of staple fibers and a filament yarn are treated.

Further, a single kind of staple fiber, a blend of staple fibers different from each other in the material, fineness, fiber length, cross-sectional configuration, crimp characteristics, elongation or the like may also be used. A blend of staple fibers different in characteristic or heat shrinkage may also be used. In the case where a blend of staple fibers different in fluid intertwining characteristics is used, the resulting yarn has an attractive cross section wherein both staple fibers are distributed in varying proportions ranging from the central portion to the peripheral portion.
  • the resulting fiber also has an attractive cross section wherein the proportions of both staple fibers in the central portion and the peripheral portion are different from each other.
  • Plural strands each comprising staple fibers different from those of the other may be separately supplied into the feed treatment zone.
  • yarns of attractive appearance are obtainable, e. g., in a structure where different staple fibers are alternately arranged in the longitudinal direction or a structure where the yarn diameter is periodically varied.
  • one or more continuous filament yarns may be simultaneously or separately supplied into the fluid treatment zone as illustrated with reference to FIGS. 7 10.
  • the filament yarn which becomes a core in the core spun yarn of the present invention comprises for example a conventional synthetic filament yarn, its crimped yarn, a textured yarn, an elastomeric yarn, a flat yarn, a gold or silver thread, a glass yarn and a metallic yam. Both multifilament and monofilament yams may be used.
  • the yarns are preferably treated with fluid in a completely opened state.
  • Textured yarns as herein used mean those consisting of either non-elastic, continuousfilaments or non-elastic staple fibers, both of which have been made stretchable through reformation for example by the heat-set coil, crimp or curl methods. It is further practicable that a latently crimped filament yarn or a strand of latently crimped staple fibers is subjected to the fluid treatment and then, heat-treated to develop crimps.
  • a core yarn When a core yarn is used, it is also practicable to subject the resulting yarn to tensioned treatment after the fluid treatment to straighten the core yarn component and hence, to make the yarn hold a firm appearance. Further, it is also practicable to twist the filament yarn before supplying it to the fluid treatment zone, to a certain extent e.g. less than 500 T/M whereby the intertwinement thereof with staple fibers is enhanced.
  • the yarn of the present invention is of high bulk and has a soft, attractive handle similar to that of conventional spun yarns.
  • the characteristic structure such that individual staple fibers are intertwined with each other to cohere into a substantially non-twist yarn, is distinguishable from conventional yarns made due to cohesive attraction such as twist, or adhesion, melting or sticking together.
  • the yarn of the present invention has the advantage of reduced surface lubrication since it has numerous fluffs of a relatively large length.
  • the spinning speed may be increased to 200 m/min or more, for example.
  • EXAMPLE 1 A roving of polyacrylonitrile staple fibers (fineness of 3 d, length of 120 mm), having a yarn number of 0.7 g/m, was drawn times its original length by a drafting means and then, fed through front rollers to the fluid treatment apparatus shown in FIG. 5.
  • the distance L between the grasping point of the front rollers (10) and the point where the intertwinement most effectively occurs was 80 mm.
  • Pressure and flow rate of both first and second air flows were 3 kg/cm and 150 l/min, respectively.
  • Peripheral speed of both the front rollers (10) and the delivery rollers (27) was 200 m/min.
  • the yarn having a yarn number of one thirty-fourth Nm,.so produced exhibited an appearance as shown in FIGS. 1A and 1B and was of high bulk.
  • EXAMPLE 2 A roving was prepared by blending two polyacrylonitrile staple fibers of a fineness of 3 d and a length of 120 mm, one being of ordinary shrinkage and the other being of high shrinkage, in a proportion of 6:4, respectively.
  • the roving of a yarn number of l g/m, so prepared, was drawn by a drafting means and then, supplied to a fluid treatment apparatus shown in FIG. 5.
  • the distance L defined herein before was 80 mm.
  • Compressed air having a pressure of 3 kg/cm was introduced through two inlets l3 and 26 into the apparatus 14, each at a flow rate of 160 l/rnin. Peripheral speed of both front rollers 10 and delivery rollers 27 was 200 m/min.
  • the spun yarn was wound into hanks, and then subjected to steaming at a temperature of C for 10 minutes under relaxed conditions to be made bulky thereby, and then rewound by a hank reeling machine. When it was rewound at the rate of 2 kg per reel, the yarn was smoothly unravelled and no yarn breakages could be observed.
  • EXAMPLE 3 A blended roving used in Example 2 and a polyamide multifilament yarn having a total fineness of 50 d and comprising 24 filaments were simultaneously supplied into the fluid treatment apparatus shown in FIG. 5. A core spun yarn of high bulk and softness was obtained.
  • EXAMPLE 4 A roving of polyacrylonitrile staple fibers having a fineness of 3 d and various lengths (average length of 150 mm and maximum length of 200 mm) was supplied to the fluid treatment apparatus shown in FIG. 5.
  • the treatment conditions were as follows:
  • EXAMPLE 5 Using a fluid treatment apparatus shown in FIG. 8, a roving of polyester staple fibers having a fineness of 2.5 d and various lengths (average length of 128 mm) and two polyester filament yarns each having a total fineness of 50 d and comprising 48 filaments were treated under the following conditions:
  • EXAMPLE 6 Using a fluid treatment apparatus shown in FIG. 9, a roving of polyacrylonitrile staple fibers having a fineness of 3 d and various lengths (average length of 128 mm) and two polyamide multifilament yarns each having a total fineness of 50 d and comprising 34 filaments were treated under the following conditions:
  • EXAMPLE 7 Using a fluid treatment apparatus shown in FIG. 13, a roving of polyacrylonitrile staple fibers having a fineness of 3 d and various lengths average length of 128 mas treated under the following conditions:
  • the yarn exhibited strong intertwinement between the staple fibers although the yam was not substantially twisted, and a considerably reduced unevenness, and was quite suitable for knitting.
  • Peripheral speed (V,) of delivery rollers 132 m/min Take-up speed 145 m/min Number of revolutions of false-twist spinner 50 l8.000 rpm Pressure of the compressed air 4.0 kg/cm a wire gauge of 300 meshes Deflecting member
  • the yarn having a yarn number of 1 I 3.5 Nm, so produced, was of very high bulk and quite suitable for various knitted and woven goods. Its workability was excellent i.e. yarn breakage was only 15.5 times/1,000 sp. hr. and yield was 97 percent.
  • EXAMPLE 9 Using a fluid treatment apparatus shown in FIG. 21, a roving of polyester staple fibers having a fineness of 1.5 d and various lengths (average length of 125 mm) was treated under the following conditions:
  • Peripheral speed (V,) of front rollers (not I03 m/min shown) Peripheral speed (V of delivery rollers (not m/min shown) Peripheral speed of take-up roller (not shown) I04 m/min Pressure of the air introduced through inlet 56 4.5 kg/cm d and 0 6, and 6 0.3 m/m, 30, 20 and 15, respectively.
