16 Claims. (Cl. 66-195) This invention relates to knitted fabrics, the present application being a continuation-in-part of my application filed on August 14, 1956, Serial No. 603,894, which matured into Patent No. 2,878,661.

It is an object of this invention to provide novel fabrics of the general category of those described in my said prior application-to wit, fabrics that can be inexpensively produced on a warp type of knitting machine. It is my further objective, however, to provide fabrics of greater density and opacity than those of my said prior invention, whereby they will have greater covering quality, and yet be of minimal thickness and extended yield, with resultant economy in production.

Another object of my invention is the provision of fabrics having the basic structural characteristics of the fabrics described in my said prior application, but also having various physical characteristics ranging from those of jerseys with different degrees of opacity to fabrics having general woven characteristics.

It is still a further object of my invention to enable the aforesaid novel fabrics to be produced by substantially the same machines and the same general knitting method employed to produce the fabrics of my said prior invention, but with the method variation of greater shoggings of either or both bars, thereby giving rise to three or more lap crossings between wales. By varying the number and position of thread crossings between wales, fabrics of various ranges of textures and novel appearance, including those that have heretofore been achieved only on weaving looms, can be produced. As in the case of the production of the fabrics of my said prior invention, only one stitch is drawn by each needle at every course, with the result that the yarns are disposed relatively in the single plane established by the tiers of single stitches formed at each course, whereby a fabric of minimal thickness can be produced. In other words, since there are no double stitches, the resulting fabric is of relatively extended yield, with maximum covering qualities for the amount of yarn used.

Other objects, features and advantages will appear from the drawings and the description hereinafter given.

Referring to the drawings,

Figure 1 is an enlarged diagrammatic view of one form of fabric according to this invention, showing the formation of the chains of elongated and contracted stitches joined by diagonal thread sections between non-adjacent and adjacent wales, the contracted stitches being, for the purpose of clarity, shown in slightly opened condition.

Fig. 2 is an enlarged diagrammatic View, substantially like Fig. 1, but showing another form of fabric of this invention.

Fig. 3 is an enlarged diagrammatic view, also substantially like Fig. l, but showing still another fabric according to this invention.

As in the case of my above-mentioned prior invention, a warp knitting machine is employed having at least two bars that are capable of wrapping around the needle, so

as to perform a knitting or stitching function in conventional manner. The two bars, threaded full, shog in opposite directions with respect to each other. According to the preferred method employed for making the fabrics of this invention, one bar knits at any course-the back bar laying-in when the front bar knits, and the front bar floating when the back bar knits.

The fabric resulting from such deployment of threads around the knitting needles is characterizedby a series of longitudinal single stitches, certain non-adjacent rows being connected by diagonal laps-although the same fabric may also have portions thereof with adjacent rows also connected by diagonal laps. These laps, arising from bars shogging in opposite directions, are in crossing relation. The knitting process is analogous to that described in my Patent No. 2,667,775, issued February 2, 1954, to the extent that the contraction of the small stitches continues to the point of coalescence, to produce a tightly knit structure. Accordingly, in the production of the fabric of the present invention, the knitting operation results in a tightening of the contracted stitches, thereby creating the appearance only of longitudinal rows of connected single stitches, the stitches of each wale being connected to stitches in another wale by diagonally crossed laps. It is important to note that when elongated and contracted stitches are made by knitting a single bar, the back bar must be inlaid in one wale, and then, as aforesaid, shogged in a direction opposite to the shogging motion of the front bar when it is once more inlaid.

In all embodiments of my invention illustrated, the fabric includes a number of vertical rows or wales of knitted stitches, as well as unknitted sections. As in the case of my said prior patent, all unknitted portions of the thread, including floats and laid-in sections, will for convenience be designated unknitted floats, regardless of whether they are technically floats or laid-in sections.

In the fabric diagrammatically shown in Fig. 1, the horizontal courses are identified by the reference letters R, S, T, U, V, W, and X; and the vertical rows or wales are identified by the reference numerals I, II, 1H, IV, V, and VI, it being understood that a multiplicity of similar wales and courses are formed during the knitting process to make the completed fabric. In accordance with the concept of my invention, a plurality of warp threads are employed to form the fabric, such as those identified in Fig. 1 by the reference letters B A B A B A B A B A B These threads are formed, by the knitting process above described, into longitudinal chains of contracted and elongated stitches such as those disposed within the Wales I, II, III, IV, V and VI, certain of the threads having portions thereof extending through contracted stitches as unknitted floats, certain other portions extending diagonally between adjacent and non-adjacent wales and in crossing relationship, as will more clearly liereinafter appear.

In the particular embodiment of my invention illustrated in Fig. 1, pairs of threads are employed, one of the threads of each pair being designated by the letter A, and the other by the letter B, with subnumerals indicating the wale in which they are shown to originate. For example, the pair of threads A and B are shown in the lower portion of wale 111, the pair of threads A and B are shown in the lower portion of wale II, etc. The A threads are front-bar threads, and the B threads, rear-bar threads.

In wale I there are a plurality of elongated stitches 9, 11 and 13, and alternately positioned contracted stitches '10, 12 and 14. Similarly there are correspondingly positioned elongated stitches 15, 17 and 19 and contracted stitches. 16, 18 and 20 in wale H; elongated stitches 21, 23, 25 and contracted stitches 22, 24 and 26 in wale III; elongated stitches 27, 29, 31 and contracted stitches 28,

30 and 32 in wale IV; elongated stitches 33, 35, 37 and contracted stitches 34, 36 and 38 in wale V; elongated stitches 39, 41, 43 and contracted stitches 40, 42 and 44 in Wale VI. It will further be observed that, in the fabric illustrated, the lowermost portions of the threads from which the stitches are formed arein course R; course S containing the elongated stitches 9,, 15, 21, 27, 33 and 39; course T containing the contracted stitches 10,16, 22, 28, 34 and 40; course U containing the elongated stitches 11, 17, 23, 29, 35 and 41; course V containing the contracted stitches 12, 1 8, 24, 3t), 36 and 42;

course W containing the elongated stitches 13, 19, 25,. 31, 37 and 43; and course X containing the contracted stitches 14, 20, 26, 32, 38 and 44. I

All the pairs of A, B threads arersirnilarly arranged in the knitting process, and their respective positions can be determined by following through each of these threads within the fabric of Fig. 1. For illustrative purposes we will follow threads A and B Thread A extends diagonally upwardly to form contracted stitch in adjacent wale I whereafter it extends upwardly diagonally to wale III, skipping the intermediate wale H, to form contracted stitch 24 therein; thereafter it extends upwardly diagonally to wale I, again skipping Wale H, to form contracted stitch 14 therein. The thread section extending diagonally'upwardly from contracted stitch 10 constitutes the lap designated 10a; the thread section extending diagonally upwardly from contracted stitch 24 constitutes the lap designated 24a; the thread section extending diagonally upward from contracted stitch 14 constitutes the lap designated 14a.

Following the path of thread B it forms elongated stitch in wale II, then it extends upwardly and is inlaid in contracted stitch 16, whereafter it extends upwardly and diagonally to adjacent wale I to form elongated stitch 11; then it extends upwardly and is inlaid in contracted stitch 12 whereafter it extends upwardly and diagonally to adjacent wale II to form elongated stitch 19; thereafter it extends upwardly and is inlaid in contracted stitch whereafter it extends upwardly and diagonally to adjacent wale I. All the other pairs of A and B threads, as aforesaid, follow similar paths in the knitting operation, to form the elongated and contracted stitches, and the unknitted floats, in similar manner. Thus, there are diagonal crossing thread sections 10a, 15c, and 18a, 11c, 24a and 14a, 190, between wales I and II; diagonal crossing thread sections 16a, 210, 10a, and 24a, 170, a, and 20a, 250 between wales II and III; diagonal crossing thread sections 22a, 270, 16a, and 30a, 23c, 36a, and 26a, 310 between wales III and IV; and diagonal crossing thread sections 28a, 33c, 22a, and 36a, 290, 42a, and 32a, 37a between wales IV and V; and diagonal crossing thread sections 34a, 390, 28a and 42a, c, and 38a, 430 between wales V and VI. The fabric also shows the above-mentioned unknitted floats, examples of which are the following: in course T, 15b extending through contracted stitch 16; 21b extending through contracted stitch 22; 27b extending through contracted stitch 28; 33b extending through contracted stitch 34; 3% extending through contracted stitch 40; in course V, 11b extending through contracted stitch 12; 17b extending through contracted stitch 18; 23b extending through contracted stitch 24; 29b extending through contracted stitch 30'; 35b extending through contracted stitch 36; 41b extending through contracted stitch 42.

During the knitting operation there results a coalescence of the contracted stitches, and an elongation of the other stitches designated elongated stitches, in the manner described in my said prior Patent No. 2,667,775. Accordingly, as aforesaid, the contracted stitches are drawn together to what appears to the eye to be juncture points between adjacent elongated stitches.

v The resultant structure has three thread crossings at each pair. of adjacent elongated and contracted stitch courses. This gives rise to a fabric having better coverage than the fabric described, in said previous patent application; yet it is of comparatively lighter structure than conventional jersey fabric produced on warp knitting machines, inasmuch as the yarns are deployed in one plane rather than having a thickness comprising several planes such as occurs in conventional jersey structures.

In the fabric of Fig. 1 above described, one thread of each of the pairs of threads in course R forms an elongated stitch in different courses of adjacent wales, the other thread of each of said pairs forming contracted stitches in dilferent courses and non-adjacent wales. Fig.

i 2 illustrates another embodiment of my invention involving the same basic concept, but differing from the structure of Fig. 1 in that one thread of each pair forms interengaged elongated and contracted stitches in adjacent wales, the other thread of each pair merely extending diagonally across a plurality of wales and having unknitted portions inlaid in contracted stitches in certain non-adjacent wales, as will more clearly hereinafter appear.

In the particular construction illustrated in Fig. 2, the fabric is formed of a plurality of threads designated C 8, D8: 9, 9 10 10 11 11, 12 and 12, the nu merals as in the illustration first above described, designating the respective wales in the lower portions of which said threads are shown disposed, to wit, the wales VII, VIII, IX, X, XI and )GI. Each wale, just as in the above-described fabric, consists of alternate elongated and contracted stitches, the fabric also having thread sections in crossing relation; but the arrangement is such,

however, that there are more crossings of these diagonal sections or laps than in said first form-the laps being closer together and thereby forming a denser fabric in those regions in which they appear. As Will appear from the drawing and the description hereinbelow given, the fabric is no thicker than that of the form of Fig. 1, nor of the forms illustrated in the parent application, since only one needle engages one stitch.

In the structure of Fig. 2 there are courses K to Q. In course K the contracted stitches (only the upper portions of which are shown) are 45, 52, 59, 66, 73 and 80. In course L there are only elongated stitches, these being 46, 53, 60, 67, 74 and 81. The other contracted stitches appear as followsin course M: 47, 54, 61, 68, 75 and 82; in course 0: 49, 56, 63, 70, 77 and 84; in course Q: 51, 5'8, 65, 72, 79 and 86. The other elongated stitches appear as follows-in course N: 48, 55, 62, 69, 76 and 83; in course P: 50, 57, 64, 71, 78 and 85. The diagonal thread sections of the unknitted threads (such as D D etc.) are 8h shown extending from wale VIII across wale VII; 9h shown extending from wale IX across wales VIII and VII; 10h shown extending from wale X across wales IX and VIII to Wale VII; 11h shown extending from wale IX across wales X and IX to wale VIII; 12h shown extending from Wale XII across wales XI and X to wale IX; 13h shown extending across wales XII and XI to wale X; 14h shown extending across wale XII to wale XI. Continuations of the said unknitted threads are shown extending in the opposite direction diagonally across upper portions of the fabric, such diagonally ex tending thread sections being identified by the following referencenumerals: 8k, 9k, 10k, 11k, 12k, 13k, 14k, extending diagonally upwardly from right to left; 8n, 9n,

10n, 11n, 1221, 1311, 1411, extending diagonally upwardly contracted stitch 63, 10m in contracted stitch 70,- 11m.

enemas in contracted stitch 77, 12m in contracted stitch 84, p in contracted stitch 51, 11p in contracted stitch 58, 12p in contracted stitch 65, 13p in contracted stitch 72, 14p in contracted stitch 79. Certain of the fabric components are omitted from Fig. 2, since those that are illustrated are deemed sufiicient for the purpose of this specification.

To show the paths of the various threads extending upwardly from course K, the paths of threads C and D will be described as illustrative of the other corresponding pairs. Thread C is knitted to form the elongated stitch 67, whereafter lap 67a extends diagonally up towards wale XI to form the contracted stitch 75 and then the elongated stitch 76 thereabove, the lap 76a of said thread extending diagonally upwardly from the bottom of said stitch 76 to form the contracted stitch 70 in wale X and the elongated stitch 71 thereabove. From the bottom of said stitch 71 the lap 71a extends diagonally upwardly, in the manner aforesaid, to form the contracted stitch 79 in wale XI.

The thread D has the section 10h thereof extending diagonally upwardly across the elongated stitches 60 and 53 of wales IX and VIII, respectively, to wale VII where it is inlaid at 101' in the contracted stitch 47; and thereafter the thread section 10k of said thread extends upwardly across the elongated stitches 55 and 62 of intermediate wales VIlI and IX, respectively, to wale X where it is inlaid at 10m in the contracted stitch 70. Thereafter the section 10n of said thread extends upwardly and diagonally across the elongated stitches 64 and 57 of the intermediate wales IX and VIII, respectively, to wale VII where it is inlaid at 10p in contracted stitch 5 1.

It will be noted that there are relatively more crossings of thread sections in the fabric of Fig. 2 than in the fabric of Fig. 1, this being due to the increased shogging movements employed in the production of the fabric of Fig. 2.. Following the course of the non-knitting thread D it will be noted that it crosses laps 60a, 53a and 46a; similarly thread D crosses laps 67a, 60a and 53a. Following the courses of the knitting threads, such as C it will be noted that their laps are crossed by a correspondingly greater number of laps from the non-knitting threads than in the structure of Fig. 1. For example, lap 53a is crossed by sections 9h, 10h and 11h of the non-knitting threads; lap 46a is crossed by sections 8h, 9h and 10k, and so on. Because of such correspondingly greater number of diagonal thread crossings, the diagonal sections of the fabric are closer together and form a denser structure, as clearly appears from a comparison between the structures of Fig. 1 and Fig. 2.

Fig. 3 illustrates still another embodiment of this invention, the fabric thereof having been made by the general method employed in the making of the fabrics of the other two embodiments above described, but with irregular bar movements whereby special textured effects have been obtained. It will be observed that each wale contains alternate elongated and contracted stitches, as in the other embodiments, but with different arrangements of diagonally crossing lap sections. It is further to be noted that in this fabric a plurality of pairs of threads are also employed, one thread of each pair forming contracted stitches in adjacent wales, and the other thread forming elongated stitches in non-adjacent wales in certain courses, and in adjacent wales in other courses, as will more clearly hereinafter appear.

In this embodiment of my invention, the fabric is formed y The threads 13, 13, ra/ 14 15, 15 E16: F16 E F E and F the subnumerals designating the respective wales in the lower portions of which said threads are disposed, to wit, the respective wales XIII, XIV, XV, XVI, XVII and XVIII. The courses of oontracted stitches are Y Y Y and Y and the courses of elongated stitches are X X and X The contracted stitches in wale XIII are 87, 89, 91 and 93; and the elon- 6 gated stitches therein are 88, and 92; the contracted stitches in wale XIV are 94, 96, 98 and 100, and the elongated stitches therein are 95, 97 and 99; the contracted stitches in wale XV are 101, 103, and 107, and the elongated stitches therein are 102, 104 and 106; the contracted stitches in wale XVI are 108, 110, 112 and 1 14, and the elongated stitches therein are 109, 111 and 113; the contracted stitches in wale XVII are 115, 117, 119 and 121, and the elongated stitches therein are 116, 118 and 120; and the contracted stitches in wale XVIII are 122, 124, 126 and 128, and the elongated stitches therein are 123, and 127.

Following the path of thread E it first forms the -contracted stitch 94 in Wale XIV, the lap 94a thereof extending diagonally upwardly to form the contracted stitch 89 in wale XIII, whereafter the lap 89a thereof extends upwardly diagonally back to wale XIV to form the contracted stitch 98, and so on. All threads corresponding to E form similar contracted stitches in this manner.

Following the path of thread F it is laid into contracted stitch 87, its section 13g extending diagonally upwardly across the intermediate wales XIV and XV to wale XVI where it interengages the contracted stitch 108 and forms the elongated stitch 109. The lap 109a from elongated stitch 109 extends upwardly diagonally across the intermediate wale XVII to wale XVIII where it is inlaid in, contracted switch 124, reversing its path whereby the section 109b thereof extends upwardly and diagonally, crossing the two intermediate Wales XVII and XVI and interengaging contracted stitch 103 in Wale XV and forming thereabove the elongated stitch 104; and thereafter the lap 104a of stitch 104 extends in the same direction upwardly and diagonally across intermediate wale XIV to wale XUI where it is inlaid in contracted stitch 91, after which it reverses its path, the section 104b extending diagonally upwardly across the two wales XIV and XV to wale XVI, to repeat the cycle.

It will be noted that the diagonal laps 10g, 11g, 12g, 13g, 14g, 15g, 16g, 17g and 18gall in course Y -are all more inclined to the horizontal than the corresponding laps in either of the structures of Figures 2 and 3. Such laps 10g to 18g, inclusive, are thus closer together and form a more dense material with less porosity at this point than the corresponding regions intersected by the diagonal laps of the structures of Figs. 2 and 3. Each of the diagonal laps extending from the threads of the contracted stitches are also intersected by more diagonal sections from the other threads. For example, lap 94a extending from co'ntracted stitch 94 is intersected by diagonal sections 13g, 12g, 11g, 88a, and 129; similarly, diagonal lap 101a extending from the bottom of contracted stitch 101 is intersected by diagonal thread sections 14g, 13g, 12g, 95a and 88a. These thread intersections give greater opacity, without increasing the thickness of the fabric. It is further to be noted that there is a variegated texture pattern, resulting from the fact that there were correspondingly Varied bar movements, in the making of the fabric, as above explained. Such varied bar movements have resulted in the arrangement shown in Pig. 3 Where diagonal thread extensions from the elongated stitches first extend across one wale in one direction, and then, reversing their directions, extend across two WEIGS, whereby a single thread is made to traverse an irregular path to create elongated stitches in adjacent wales.

In the three embodiments shown, thread portions are brought diagonally across more than one wale, although the same fabric may include portion in which diagonal thread sections extend only between adjacent wales. All the embodiments of fabric illustrated, and produced according to this invention, have portions with less porosity, and are of greater density, than the fabric according to the parent application. Yet, despite the greater opacity, the fabric is of low bulk, whereby considerable economies are effected, since one stitch is in each case drawn by each needle at every course, but with more lap crossings between wales than appears in the structure of my said prior invention.

In the embodiments of Figs. 2 and 3, just as in the embodiment of Fig; 1 and in those shown in the said parent application, the knitting operation causes a coalescence of the contracted stitches, and an extension of the elongated stitches, so that the contracted stitches are drawn together at juncture points between elongated stitches.

Although the above description sets forth three examples of fabrics according to my invention, it is evident that by combining regular and predetermined irregular bar movements various other texture eifects and degrees of opacity can be obtained.

In forming the fabric of Figure 1, the following fo'rmula is employed:

I '2-0, 4-4, 4-6, 2-2 II 4-4, 2-0, -0, 2-4

' In forming the fabric of Figure 2, the following formula is employed:

In forming the fabric of Figure 3, the following formula is employed:

I 2-0, 2-2, 2-4, 2-2 II 12-12, 6-4, 0-0, 6-8

These formulae are Raschel designations that can be readily resolved as Trico' designations by anyone versed in the art. 7 In the above description, the invention has been disclosed merely by way of example and in preferred manner; but obviously'many variations and modifications may be made therein. It is to be understood, therefore, that the invention is not limited to any specific form or manner of practicing same, except insofar as such limitations are specified in the appended claims.
