claim: 1. A woven laundry-stabilized fabric composed of three different groups of single yarns, the flrst group of yarns being substantially entirely of staple rayon fibres, the second group of yarns being substantially entirely of spun vegetable fibres and being interspersed with the first group of yams throughout one dimension of the fabric, and the third group of yarns of at leasl flfty percent of spun rayon fibres and being inl@(,, woven with the first and second groups of yarri--l at right angles thereto. 2.' A woven laundrystabilized fabric composed of three different kroups of single yams, the first group of yams being substantiau y entirely of staple rayon flbres, the second group of yams being substantially entirely of spun vegetable fibres and being interspersed with the flrit group of yarns throughout one dimension of the fabric, and the third group of yams of a spun admixture of vegetable and rayon fibres and being 10 interwoven with the first and second groups of yarns at right angles thereto. 3. A woven laundrystabili7,ed fabric composed of three different groups of single yarns, the first group of yarns being composed of at least seventy 15 percent of staple rayon fibres, the second group of yarns being composed of at least seventy percent of spun vegetable fibres and @eing interspersed with the first group of yams throughout one dimension of the fabric, and the third group 20 of yams being composed of a spun admixtur6 of staple rayon and 'vegetable fibres in approximatel y equal proportions and being interwoven with the first and second groups of yarns at right angles thereto.

Patented Sept. 14, 1943 2 1 3 2 9 , 4 5 2 UNITED STATES 'PATENT OFFICE 2,329,452 TEXTME FABRIC Godfrey Bloch, New York, N. Y. Applicatiou May 17, 1939, Serial No. 274,210 3 Claims. (Cl. 139-426) This inventioii relates to an !Mproved textile fabric, and more particularly to a fabric suitable for men.'s shirtings, as well as for uniforms, aprons, and launderable dress goods generalISr, in all of which dimerisions must be maintained r) in the finished article. It is one object of this invention to provide a; fabric suitable for such services which is capable of repeated, launderings, and which may be stabilized in width and length so as to be substan- 10 tially free from shrinkage and sfretch. It is another obje ' ct of this invention to provide a fabric of the above indicated character in which a very desirable lustre and sheen is obtained in a fabric which is economical to manu- 15 facture and produce. It is a further c;bject of this invention to provide a fabric of the above indicated character which in the finished fa;bric has the necessary stability and wet strength within given commer- 20 cial weights. According to this invention the above gnd other desirable object . s are accomplished by a particular arrangement or arrangements of cotton and spun rayon yarns. 25 It is true that launderable fabrics have heretofore beeri made by blending cotton and spun rayon but, among other objections, sorae of the softness and lustre of the rayon staple is lost so that the same Is not so suitable for shirtings, 30 for example. Other fabrics have been made by -t@*isting cotton and spun rayon yarns together, and weaving the same into cloth, but for given yarn sizes such fabrics are of 'relatively open mesh or of heavy weight by virtue of their two- 35 i@ly construction. Excessive weight renders fabrics unsuitable for men's shirting, and of course they are more expensive thari i I f made with single yarns. T'hat is to say, cloths made of two-ply yarns, 40 one thtead of cotton. and one of spun rayon yarn twisted together; vihen of the right weight for dress shirtings, pyjamas, etc. (about, 3.50 to 4.50 sq. yds. per lb.)'' are too. open weave; and when woven closely @nough with yarns of the 45 comme.rcial sizes,,20's to 40's two-ply, the fabrics are too-heavy; alid if made of two-ply of very fine yarns, guch as 50 to 80, the fabries.become too expensive. Cloths made entirely of spun rayorl cannot be 50 stabilized against shrinkage and stretch within the low limits of the exacting requirements of these trades, and cotton'cloths lack the softness and desirable:ftnish appearance of iayon. T'ne present invention overcomes all these dif- 55 ficu-Ities by making a warp with two sets of single yarn warp threads, one 'set of cotton or bther vegetable fibres, and one set of spun rayon fibres, and a single filung or weft yam which is a -blend of spun rayon and cotton :ftbres. Cloths properly made of such a combinatioii of cotton and spun rayon can be stabilized within the liralts required for a considerable number of commercial uses, particularly for garineri@ts customarlly laundered by machinery. @ Flurthermore, they are capable of being firlished stable to a stretch or shrinkage factor below one to two percent. The warp threals -may alternate one cotton and one spun rayon, or four cotton and four spun. rayon, rnore or less, but the niimber of threads bf each grt)up need not be equal. The threads or groups may be arranged in regular alternatioris, or may be varied to form visual effects, or patternsi as the spun rayon will normally glisten above the cotton. The two sets of warp threads will normally be on one warp beam, and the cloth may have colored warp strip6s or other decorations on the same be-am or on an additional beam, as desired. The cotton ends should be substantially all cotton, that is, they should not be weakened or made unstable by any large admixture of other fibres., The cotton ends should normally range from seventy to one hundred percent cotton staple. Also the spun rayon ends should not contain any substantial admixture' which will detract from their softness, and normally should have no less than seventy per . cent of rayon staple. The filling normally will consist of a blend t)f A spun rayon and cotton in approximately equal proportions. Where strong and stable yarn is obtained In blending cotton and spun rayoxi, as b)@ the use of high tenacity rayon staple, such blend inay be substituted for the cotton threads In the warp. Fabrics made in accordance with the aforesaid invention will attain the necessary stability, wet strength, a.nd other objibcts of this invention within given cbmmercial weights, as well as at a cost making the same useable for shirtings, pyjama cloth, dress goo&, etc. The drawing illustrates in M.'gure 1 a diagrammatic, fragmentary face view of a ejoth made according to this invention; Mg. 2 is a sectional view taken on the line 2-2 of Mgure 1 and Flgure 3 is a sectional view taken on the line g@3 of Mg. 1.
