FULLED wovEN Fannie.'

Application led lay 6, 1925, Serial No. 28,490,9.1-111 inl Germany lay 20, 1924.

In the ordinary fulledfabrics with rectangularly crossing warp and weft threads, the warpthreads extend in the lon itudinal direction and the weft threads in t e transverse direction of the fabric. The same is the case in garments and other articles made of. such fabrics. If thisv fabric or articles made thereof are submitted to tensile stresses in the longitudinal direction, it will only be the warp threads which will oppose resistance to the stresses, while the weftthreads i'emain`entirel inactive. It will be inverse if the fabric 1s placed under stress in the transverse direction. 'I The invention has for its object to rovide a fulled woven `fabric in whichA t e recL tangularly `crossing warp-and weft threads extend diagonally with relation to the edges of the fabric.

In the accompanyin 2 illustrate, by way 0% manufacturing'a' 'fabric according to the present invention. I

In a manner known per se, the fabric is drawing Figs. 1 and 25 first woven in the form of a tube a,.Fig. 1,

yin which the warp threads extend longitudi nally and the weft threads transversely. The tube thus formed is then cut up alonga helical line b into a simple web of fabric c,

shown in.Fig. 2. As will be seen from the last-said figure, the warp and weft threads while crossing rectangularly extend diago-I nally with relation to theedges of the fabric. A fulled'fabric according to the present invention possesses numerous advantages over the ordinary" fulled fabrics vin which the warp threads extend in the longitudinal and the weft threads in the transverse direction. i The present fabric is very ductile both in the 40 longitudinal and transverse direction, i. e. in the directions in which garments made of the -fabric are submitted to tensile stress.

' Besides, in making garments, covers, etc. of the fabric'the edges need not be' provided with seams but 'they can remain open even if the fabric is made of cheap raw materials such as, for instance, of sho dy. Since the V warp and weft threads-form anA acute angle edges.

example, a mode of valon with the fabric edges so that no thread extends paralleli-y of the same, the felting of the threads obtained by the fulling operation keeps the threads together in such a manner as to render impossible a feazing of the greater tensile strength than the old fabrics because any longitudinal and tarnsverse stresses are taken up by the warp and weft threads inlcommon. Therefore, raw materials of comparatively minor quality may be used for manufacturing a cloth-of definite strength.

As the fabric is lyieldable in two directions..

garments made from the saine will fit better than garments of the ordinary fabric.

Owing to thegreater strength or resistibility of the fabric in the directions in which the tensile stresses are mostly exerted, it can 'The present fabric further has al be made of less threads per unit of area than 'the garment cloth used hitherto.' Thereby, theI cloth4 becomes cheaper and' lighter, while nevertheless a high density and insulative property may be imparted to it by an lefficient raising and fulling operation.

Having thus described my invention, what I claim as new and desirek to Secure by Letters-Patent, is I 1. Al'nethod of producing a fulled woven'. fabric, consisting in weaving the fabric in tubular form, cutting said fabric tube a helical line to provide a web .of fabric in which the rectangular crossing warp and weft threads extend diagonally with relation to the longitudinal edges ofthe fabric and iinishin the fabric to* full the same whereby in t e ful'ling operation the and weft threads are equallygengaged warp Aby. t e finishing instruments.'

'2.l Asa new product, a fulled woven fabric in which the crossing warp and weft threadsv extend diagonally'to the respective edges of the-fabric.

. In testimony whereof Lhave signed my name tothis specification. a
