Definitions

  • ABSTRACT A double threaded spreader roll to separate the fila ments of a continuous multifilament yarn to allow sta ple yarn to be placed among the separated filaments and the yarns to be twisted together to form a yarn having the strength of filament yarn and the appearance of spun staple yarn.
  • ATTORNEY They have, as a general rule, the disadvantage of a relatively low tensile strength and in addition have disadvantages which are characteristic of the type of fiber or fibers employed in their formation.
  • the filament yarns are generally employed in the manufacture of sheer hosiery or other sheer dress goods and have the primary advantage of a high tensile strength as compared to that of the spun yarns. They have the disadvantages of resulting in fabrics which provide poor cover and which have a low heat insulating value.
  • attempts have been made to combine staple fiber materials and filamentary materials to thereby obtain in a single yarn the advantages of both the spun yarns and the filament yarns but previous to this invention, such combination yarns have not been completely satisfactory in all respects.
  • the yarn produced by this invention is preferably prepared by bringing together a drafted ribbon or the like or fibrous material and a ribbon of separated filaments and thereafter twisting the two together into a unitary strand.
  • the ribbon or fibrous material can readily be prepared by passing sliver or roving between a plurality of pairs of drafting rollers rotating at different peripheral velocities, such as is done in the conventional spinning of staple fiber yarns.
  • the filamentary ribbon can be formed by separating the component filaments of a multifilament yarn, having little or no twist, and thereafter placing the yarn under a very low tension so that the filaments are free to separate.
  • the ribbon of drawn fibers and the ribbon of filamentary material are best brought together by passing the two in superimposed relationship between a pair of driven'rolls, such as illustrated by the delivery rolls of a drafting frame.
  • the two ribbons are then twisted together, at the point where they are delivered from between the driven rolls, by any suitable conventional means such as, for example, a ring and traveler spinning array.
  • FIG. 1 is a schematic view in perspective of apparatus suitable for producing the desired yarn
  • FIG. 2 is a blown-up view of the yarn combining portion of the apparatus shown in FIG. 1;
  • FIG. 3 is an enlarged view of the multifilament yarn spreader roll
  • FIG. 4 is the spreader roll cut in half and spread out flat to illustrate the operation of spreading the filaments of a multifilament yarn.
  • the reference numeral represents a yarn supply package of multifilament yarn, such as Dacron, and the reference number,l2 represents a sliver or roving package such as wool.
  • the roving 14 from the package 12 is supplied to the drafting system 16 through a trumpet 18 mounted on the traverse bar 20.
  • the drafting system 16 is conventional in that it consists of three sets of drafting rolls 22, 24 and 26. Each of the three sets of rolls have an upper and lower roll in nip forming relationship with the front rolls 22 being driven faster than the middle rolls 24 and the middle rolls 24 being driven faster than the rear rolls 26 to draft the roving 14 being supplied thereto.
  • the multifilament yarn 28 from the package 10 is delivered through conventional tension device 30 and over a series of guides 32 to the spreader roll 34 driven by motor 35.
  • the multifilament yarn in a manner hereinafter explained, is separated into a plurality of its individual filaments and is delivered into the back of the nip of front rolls 22.
  • the separated multifilament yarn 28 is delivered under the roving 14 in the nip of the front rolls so that the roving will lie essentially in the center of the separated multifilament. From the nip of the rolls 22 the multifilament yarn 28 and the drafted roving 14 are twisted together by the conventional ring and traveler 36 and taken up on a bobbin 38.
  • the yarn thus produced will be a composite yarn having the strength of a filament yarn, imparted by the Dacron, and the appearance of a spun staple yarn due to the wool yarn.
  • the yarn will take on an appearance very similar to that shown in FIG. 13 of U. S. Pat. No.
  • the spreader roll 34 is preferably made from metal and has a right hand thread 40 and a left hand thread 42 formed therein by any suitable method. Since these threads are formed in an opposite direction, a plurality of cross-over points are formed in the spreader roll 34.
  • FIG. 4 assume that a single strand of substantially O-twist continuous multifilament yarn 28 is delivered to the roll 34.
  • This strand has a certain preselected number of individual filaments therein.
  • the multifilament yarn will divide and a portion of the individual filaments will follow the groove 46 and the rest will follow the groove 48.
  • the portion of the strands in the grooves 46 and 48 will divide once again.
  • the separation of the individual strands will back down the yarn to acertain point 52.
  • the spreader roll 34 is driven in a direction opposite to the direction of travel of the yarn 28 to enhance the spreading of the individual filaments.
  • Other factors such as the number of grooves per inch in the roll, roll speed, yarn speed, denier of the yarn and tension alsocontribute to the spreading of the individual filaments.
  • the filamentary component of the yarn of this invention can comprise natural fibers, such as silk, as well as synthetics such as viscose rayon, acetate, rayon, nylon, polyester filaments such as those formed from a prod uct produced by the reaction of te rephthalic acid and ethylene glycol and sold under the trade mark Dacron, acrylic fibers such as those formed from a product produced by the polymerization of acrylonitrile or by the copolymerization of acrylonitrile and a minor amount of another polymerizable monomer and sold under the trade marks of Orlon and Acrilan, or any other type of filamentary material, commercially available.
  • glass or metal filaments may even be employed.
  • the staple fiber material may be of natural origin and may comprise cotton, wool or fiax, or it may be of synthetic origin.
  • staple fibers formed by cutting filamentary material of any of the above-described types into staple length may be suitably used in the formation of the new yarn of this invention.
  • the particular choice of filamentary material and of staple fiber material depends entirely upon the combination of propertiresdesired in the finished yarn. For example, if one desires a fabric similar to conventional cotton fabrics but having greater strength and crease resistance, one can employ cotton fibers in combination with polyester or nylon filaments. Likewise, if one desires a fabric having an appearance and utility similar to that of conventional woolens one can employ a mixture of wool fibers and polyester or acrylic filaments.
  • the length of the fibers in the fibrous material is an important consideration since if the mean length of the fibers is too short, a ribbon of the same cannot readily be formed by drawing and, in addition, the resulting composite yarn may have a marked tendency to shed or lose the sample material.
  • fibrous material having an average length of at least about /2 inch should be utilized and the average length of the fibers is preferably at least about of an inch.
  • the filamentary strand from which the yarns are prepared should preferably contain at least about to 10 filaments since if the number of filaments is below this figure, the staple material may not be adequately secured in position.
  • Another advantage of employing filamentary strands containing at least about 5 to 10 filaments is that they are more readily available and generally are less expensive than strands with a smaller number of filaments. There is no upper limit as to the number of filaments that the filamentary strand may contain except that imposed by availability.
  • the ratio of fibrous material to filamentary material may vary within wide limits and depends to some extent upon the intended use of the yarn. If one is not interested in producing yarns which have the general appearance of spun yarns and is interested only in obtaining a novel appearance such as can be obtained with slubbed yarns, the percentage of fibrous material may be as low as a fraction of one percent, but if it is desired that the yarn have the general appearance of a spun yarn, best results are generally obtained from combinations wherein the staple fibers constitute from about 30 to percent by weight of the yarn.
  • the amount of twist that should be inserted in the filamentary strand, following its contact with a suitable source of staple fibers, to adequately secure the fibrous material in position should be at least about 5 turns per inch and preferably at least about 10 turns per inch. This additional twist forces the filaments of the strand together and thus secures the fibers firmly in position so that they are not readily dislodged.
  • Apparatus to produce a composite yarn of continuous fibers and staple fibers comprising a pair of driven delivery rolls, means to supply staple fibers into the nip of said delivery rolls, means to separate a continuous multifilament yarn into a plurality of continuous filaments, means to supply said separated filaments into the nip of said delivery rolls and means to twist said staple fibers and said filaments, said means to separate a continuous multifilament yarn being a roll member'rotatably supported in the path of travel of the multifilalength of said roll.
