Patented ct. 17, i950 iUNITED STATES PATENT OFFICE YARN AND FABRIC AND METHOD F MAKING SAME Eric E. Weiss, White Plains, N. Y., assignor to United Merchants & Manufacturers Inc., Wilmlngton, Dei., a corporation o! Delaware Application March '7, 1946, Serial No. 652,563

(Cl. 57-l40) Claims.

This invention relates in general to yarns, and more particularly to yarns similar to or having the appearance of spun yarns, although formed at least in part. from continuous filaments of yarn material. i

The invention is particularly suitable and useful in the production of light weight or sheer fabrics. One object thereof is the production or manufacture of a synthetic yarn, characterized by or having the property of high wet and dry strength; even though one of the components of the yarn such as, for example, rayon, may have a relatively low dry and wet strength. A further object is to make a yarn fabric comprising synthetic materials and resembling spun yarns, which will have dimensional stability, so that it cannot sag or, conversely, stretch, to the same extent as a fabric made wholly from spun yarn.

The present invention contemplates a syn thetlc yarn fabric of high wet and dry strength, that will be at least equally as stable as cotton fabrics that have previously been subjected to the process commonly known to the trade as sanforizing, for shrinkage limitation or prevention. Another object is a dimensionally stable synthetic fabric having the appearance of spun yarn fabric and a soft wooly texture, but comprising in part a continuous filament, which is washable and can be dry cleaned. Still another obiect is the production of such a yarn in an efficient and inexpensive manner.

With the above and other objects in view, as will be apparent, this invention consists in the construction, combination, and arrangement of parts, all as hereinafter more fully described, claimed and illustrated in the accompanying drawings, wherein:

Fig. l illustrates schematically a conventional spinning frame equiped with the standard three roll drafting system, wherein the positions ol the various elements during the spinning operation are shown; and

Figs. 2 and 3 are enlarged representations of the yarn embodying the present invention, showing its cross section and external appearance.

The instant invention contemplates the production or manufacture of a synthetic fabric characterized by high wet and dry strength and dimensional stability; and proposes to accomplish this by the composite association of a oontinuous filament core with a drafted yarn wrapping made from staple fibers. The material forming the core may be, for example, what is sold on the open market under the trade name of nylon. A copolymer of vinyl chloride and vinyl acetate is another commercially known example. Polyacrylonltrile fibers, formerly available for experimental purposes under the trade name ber A" and now sold commercially as "orion," are also recommended for the core. Other threads made of polymerized polyamides are also considered suitable for the purpose, provided they possess the characteristics of dimensional stability and high wet and dry strength. Preferably, the continuous component should be thermoplastic. In any case, however, nylon and a copolymer of vinyl chloride and vinyl acetate have been found particularly suitable and satisfactory. The wrapper component may be one or more rovings of spun rayon, spun acetate, or a blend of both in any desired percentages. Other synthetic fibers, or wool, may also be blended in with the rovings of rayon, acetate or both.

As will be understood, one or more rovings made of one of the materials above indicated, are introduced into a conventional spinning frame, and submitted to the usual drafting operation. The filament core of nylon, a copolymer of vinyl chloride and vinyl acetate polyacrylonltrile, or other suitable material, which should be finer than the rovings. is set in under the front or delivery roliers, thereby escaping the attenuating action of the drafting rolls, to coact with the roving and form a composite twisted yarn, wherein the nylon forms a core around which the roving is twisted or wrapped. Among other properties, the resulting yarn or fabric will have the characteristics previously set forth. That is to say, it will not stretch as readily or sag as much as a fabric made from all spun material. Further, the continuous filament core of nylon or other material imparts a higher wet and dry strength than spun yarns made from short fibers of the same chemical description. It is also to be noted that when utilizing thermo-plastic yarns such as nylon, a copolymer of vinyl chloride and vinyl acetate poiyacrylonitrile, cellulose acetate, etc., it is possible to shrink the filament core by means of heat treatments at high temperatures. to thereby fully set the filament yarn in a fixed position. As a result, despite the spun ilber content of the roving component or element. the composite yarn fabric is dimensionally stable and not subject to any substantial shrinking, sagging, or stretching. Itis washable, can be dry cleaned, and is characterized by a wet and dry strength superior to that of a fabric made from spun yarns only, although there is very little difference in the finished appearance of both fabrics.

Reference being made more particularly to ananas the drawings. Ill designates a bobbin stand or creel forming the upper part of the center of a spinning frame. The bobbins il-I2 for the several strands of roving are mounted in the stand l by means of skewers l3-II, and are rotatable therewith to unwind the rovings I-IB of rayon or other synthetic material from the bobblns I l- I2. The rovings IS-IG then pass through pairs of nipping rollers l1-l8, of which the pair IB revolve at a rate of speed greater than that of the pair l1, to such an extent that in passing through the rollers l1-l8, the rovings iS-IG are drawn out and attenuated to predetermined lengths. Thus the rovings IS-It are extended or attenuated to an average length of approximately the distance between the several pairs of drafting rollers |1-IB. After passing through the drafting rollers i1-I8, the rovings IS-IB advance through a third pair of rollers, which for convenience may be termed delivery rollers Il, to coact with a continuous filament thread of nylon, a copolymer of vinyl chloride and vinyl acetate or other suitable material as will be described.

Positioned adjacent the rollers |1-l 9, is a third bobbln for the fine nylon thread, or thread of other suitable material which is mounted in the rack 2| to rotate with the skewer 22. As the bobbin 26 rotates, the continuous filament nylon yarn 23 is fed through an aperture in the yarn guide 2l and between the pair of delivery rollers I9, to coact with the drafted staple fibers of rayon I5-I6. Since the continuous filament yarn 23 does not pass through the nipping rollers IB-I'L manifestly it is not subjected to any attenuation action and therefore retains its undrafted and continuous character.

The associated yarns IS-Ili and 23 issuing from the delivery rollers I8 through the guide 25 are twisted by means of the ring spinning device 26, the heavier rovings IS-IB of rayon being twisted about the finer continuous filament 23 of nylon, to form a composite yarn 21 consisting of a nylon core having a drafted rayon wrapping of staple fibers.

The composite yarn 21 is materially strengthened by the continuity of its filament core 23, and, by reason of the spun rovings IS-IG, presents an appearance like that of spun yarn, thus permitting the making of a fabric of Wooly and soft texture. Furthermore, since the core 23 is thermo-plastic, it will beY understood that by conventional heat treatment, it may be shrunk and fully set as desired. Thus a fabric made from such a composite yarn will have dimensional stability and high wet and dry strength. It is washable and can be dry cleaned, and is materially stronger than a fabric made from spun yarns only.

Although nylon, pclyacrylonitrile and a copolymer of vinyl chloride and vinyl acetate have been cited herein as examples of material suitable for use as the core 23 of the composite yarn 21, it will be understood that any synthetic substance may be substituted, if it has the properties of high wet and dry strength and dimensional stability. A thermoplastic material for the core 23 is especially suitable. In like manner, spun acetate may be used in place of the rayon wrapping threads I5-l6, or a blend oi' both, or other synthetic fibers, or wool, may be utilized. The term staple fibers as used above and claimed hereafter is intended to include discontinuous natural or synthetic bers of any predetermined length, as for examples, spun rayon, spun acetate, cotton fibers, wool fibers, and other natural or synthetic fibers or blends and mixtures thereof.
