Description
R. GROSSER July 10, 1956 COMBINATION ELASTIC DOUBLE DOUP HARNESS FABRICS Filed May 18, 1953 HWENTORl ATTORNEY United States Patent O COMBINATION ELASTIC DOUBLE DOUP HARNESS FABRICS Richard Grosser, West Englewood, N. J.
Application May 18, 1953, Serial No. 355,699
3 Claims. (Cl. 139-421) This invention relates to woven fabrics such as are used for wearing apparel and particularly those which are elastic for conformability to the shape of the wearer and yieldable to body movements, but with unique firmness in the weave so that in the process of stretching or contraction of the elastic elements there will be a minimum of slippage of elastic elements with respect to the rest of the fabric and therefore a maximum of stability and retention of original flatness and smoothness of the whole fabric as woven.
The primary object of the invention is to provide a novel method of gripping the elastic weft (filling) elements by the reverse twisting of double doup warp (leno pairs) which are provided at intervals weft-wise of the fabric. Interposed lbetween the double doup warps are groups of straight warps, regularly woven with the weft. The gripping effect on the elastic weft elements is maximized by greater frequency of occurrence of the pairs of double doup warps and also by the greater frequency of their reverse twisting about each other and about the elastic weft elements, the greatest benefit being gained when one elastic weft thread is alone engaged in a twist of the double doup threads.
Another object is to provide a practical and simple means for weaving a large variety of stable elastic patterns by varying the ratio of regular to double doup twisted warps, and also by interposing inelastic between elastic weft threads in varying degrees; but still incorporating the reverse twisted doup pairs at effective intervals and with the reverse twists located closely about the elastic weft threads for greatest firmness.
For the purposes of this description the meaning of doup is given the same as leno and double doup is an adjacent leno pair. Regular warps are understood to be straight or untwisted with respect to each other, only interlaced or woven in the usual ways with the weft threads.
The nature and properties of the fabric of the present invention will be more fully understood from the following description considered with reference to the presently amended drawing.
In the drawing:
Fig. 1 is a plan view showing an arrangement of the weft and Warp threads wherein the doup pair is forward or reverse twisted about each alternate elastic weft thread;
Fig. 2 is a plan view showing a modified arrangement of the threads wherein the doup pair is forward or reverse twisted about each third elastic weft thread;
Referring to the drawings, warp threads a and b in Fig. 1 are a pair of forward and reverse twisted doup warps. These warps are preferably inelastic material ice such as natural or synthetic fiber yarns. Interposed between such pairs of leno warps are regular warps c. These regular warps are also preferably of inelastic material such as natural or synthetic yarns. Weft threads or picks l, 2, 3, 4 as shown in Fig. 1 are of elastic construction. While generally all of the weft threads will be elastic, if desired, inelastic yarns` may be interposed providing that the elastic influence of the intervening weft threads is not unduly compromised.
In Fig. 1 it will be noted that the doup warp threads are reversibly twisted about each alternate elastic weft thread or pick, there being a single pick between consecutive reversals of said doup threads. This is a method by which the elastic weft threads can be very firmly gripped. If it is determined that a somewhat less firm grip on the elastic threads is satisfactory in a particular case, the arrangement shown in Fig. 2 may be used.
In Figure 2, the weft threads are indicated Iby numerals 1', 2', 3', 4', 5 and 6, the regular warp threads indicated by letter c', and leno warps by letters a', b. It will be noted that here the doup thread pair is reversibly twisted about each third succeeding elastic weft thread or pick, there being two picks between consecutive reversals of said doup threads, and the arrangement repeating itself after six picks.
By the use of my construction, a fabric results which is firmly held together by the double doup leno and the give of the elastic filling is such that the lightest and also the heaviest weight fabrics have the clinging character of knit (loop) construction, with the advantage that the stretch is limited to weft-wise only and stable warp-wise. Garments made from such fabrics will not sag as do knitted goods and will retain their original shape without puckering or wrinkling as is commonly experienced with elastic thread fabrics where slippage occurs when the elastic threads are not gripped firmly.
I claim:
1. A woven fabric comprising inelastic warp threads and elastic weft threads, said warp threads comprising reverse twisted pairs of leno warp threads and regular warp threads, said regular warps -being interposed between said leno pairs, said leno pairs being reverse twisted so as to grip one pick at each reversal, and at least one intervening pick between said reversals at the crossing area of said lenos.
2. The fabric as defined in claim 1, in which there is a single intervening pick between said reversals.
3. The fabric as defined in claim 1, in which there are two intervening picks between said reversals.
