40 Claims. 1

This invention relates to knitted fabric and to methods of producing the same. More particularly it concerns knitted fabric having knots therein.

For many years the'arthas sought fabrics hav- 11 various qualities not possessed by ordinary Among these :are combinations of firmness andyieldabilitynot at present possessed by either knitted or wovenfabrics; nonrun and non-ravel tendencies, the presence of firmly secured bunchesof yarn; simple and effective terry-like structures; well secured and relatively inelastic lace work, and good design qualities.

Among the objects of the presentinventionis the-provision of fabrics having one or more of the foregoing and other qualities.

The invention finds highly effective application in a wide variety of types of; fabrics including toweling, hosiery, sportswear, nether garments, outer wear, and plush fabrics. It enables the production of highly efiective run-resistant fabrics suchas non-run hosiery, girdles and brassiresg the employment of the invention being of particular importance when an elastic yarn is included.

In accordance with the invention knots are provided in knitted fabrics throughout the same or preferably at selected portions thereof. A form of knot contemplated by the invention in certain of its aspects is one wherein one extent of yarn passes through the bight of a loop thereof to form an eyelet through which another extent of yarnpa'sses. More specifically, the shank portion ofa loop comprising the two sides or legs of the loop extends through the bight of said loop and around a portion of the other extent of yarn,

which portion is itself preferably in the form of a'loop. Such knots maybe formed by doubling thelegs of a'l'oop back toward the bight and then passing them through the bight, or by bending back thebighthalf of the loop and folding it over the shank half, or otherwise bringing the two sides of the loop together with the bight end -lying aga-inst them sothat there is formed an eyelet portion in: which the two sides of the loop form adOubIe-eye extending from the end of the bight backto and through the bight. The eyelet thus formed may receive the other extent of yarnmore specifically, 'a loop thereof-and when the first extent of yarn is tightened as byrpulling the legs of the first mentioned loop through the bight the eyelet is tightened against the legsxof The loop of the showing the -section or other extentoi yarnextends from this knot as a succeeding loop in the same Wale as the l p which terms: th yelet.

Fig. 20 shoWs diagrammatically a manner of formation of the fabric of Fig. 19; and

Fig. 21 is a view like Figs. 2 and 12 showing further the contour of the various yarns in the fabric of Fig. 19.

Shown in Fig. 1 is a fabric wherein the knitting is generally of the jersey type, plain loops being knitted to plain loops at some points, as for example at 8. At other points, however, a knot 9 is formed as by first passing the sides I I and I2 of a loop I3 through the bight I4 thereof, or otherwise, to form an eyelet I5 and passing the new loop I6 through the eyelet instead of through the loop. In this manner there is formed a knot which not only adds to the firmness and body of a fabric in which it is incorporated, but tends to prevent pulling out of yarn and to prevent those 'runs which are so greatly to be avoided in knitted fabrics. In Fig. 1 the knots are, for sake of clearness, shown in a very loose condition. A normal tightened knot is shown in Fig. 2.

In addition the invention finds advantageous application in the production of design fabrics. Commonly the knots will be arranged to outline or otherwise mark the design, though if desired the main body of the fabric may be knotted throughout except at the design portions; or the "knotted and unknotted points may be substantially equal as in Figs. 1 and 3.

In Fig. 3 the knots 9 are indicated by crosses, and ordinary jersey loops are shown by dashes.

Another feature of the invention is that dangling loops can be readily provided by knotting the fabric in the second course prior to the one brush to form a very effective plush, may be thus provided. Various design fabrics can likewise be provided by dropping stitches after knotting. The design effects thus formed may be employed alone or may be coupled with the feature of intermingled normal loops and knotted knitting.

In Figs. 4 and 5 there is shown a design fabric embodying both a knotted design and a dangling loop design. In course a of Fig. 4 there is jersey knitting in all three wales shown. In course b the fabric is knotted in each wale. In course 0 there is jersey knitting in each wale. the loops being caught in the knots, In course 11 there is jersey knitting in wales I and 3, while in wale 2 a stitch has been dropped to leave a dangling loop I8 in course 0. Jersey knitting follows; the yarn of course 6 being again caught in in wale 2, and jersey loops bein present in an three wales 'incourse f. In Fig. 5, there is shown a fabric of alternate wales in alternate courses, and in intermediate wales in intermediate courses. A fabric of this type is shown in Fig. 6. From each knot 9 there extends a dangling loop I8 which in and in the preceding figures.

is firmly secured and which can readily be formed of any desired size. Such fabrics can be used for towelings; and similar fabrics, when brushed, can provide very effective plush goods.

In Fig. 7 there is shown a portion of a selvage edge fabric embodying the invention. The fabric is a plain jersey knit except at its edges, one of which is shown at 2| and another at 22, Each loop in the last course at the edge 2| and each loop in the last wale at the edge 22 is, as will be seen, knotted at 9 to provide an effective nonravel edge. The cut ends of yarn along the selvage edges is shown frayed to distinguish from the yarn ends along the broken edges of the diagraminatic view of the fabric.

Similarly a feature of the invention is the provision of a knot at the point where a wale terminates when the fabric is removed as in the formation of a full fashioned stocking. In Figs. 8 and 9 this is exemplified by the knots at 25. Selvage edge knots at 26 and non-run knots at 2! are also provided, these being formed in alternation in both directions with unknotted interknitted loops.

In instances where a heavy, firm, and/or nonrun fabric is desired, the invention is highly advantageous, even when no design features are present. In such cases knots may be provided at all or at alternate points of interknitting in the wales and/or courses. Fabrics of this type, whether or not small unknotted design portions are included, have the firmness and strength of woven fabrics while retaining a sufiicient degree of yieldability to provide sportswear and other clothing which has a closer fit and a more comfortable hang than if made of woven cloth. Towels, wash cloths, and like fabrics are effectively provided by the presence of relatively bulky knots. Many other advantageous uses will be apparent. One very effective use is in non-run hose wherein the knots prevent the spreading of a break in the yarn. Such a fabric is shown in Fig. 10, a 9 knot being provided in this instance at each point where the loops are interknitted.

In Fig. 10 there is also exemplified a manner of formation of knots of the character shown there- There is shown in stage I a loop I3 ready to be knotted. At stage II, the bight end of the loop I3 is shown spread outwardly at 29 and 39. This step is not essential but is a convenient first step of formation of the eyelet I5. In stage III, the bulged out bight portion is shown bent under the shank portion of the loop. In stage IV, the portion 29 is shown as bent over alongside the portion 30 so as to provide the double-eye construction forming the eyelet I5. Another extent of yarn, such as a loop I6, is then inserted in stage V. In stage VI, this loo-p I6 is drawn out. In stage VII, the eyelet is tightened to complete a highly effective knot 9 as by pushing the bight end toward the newly inserted loop I6. It will be appreciated that it is the formation of the eyelet and the passing therethrough of another extent of yarn that is of major significance in the present meth- 'two extents of yarn, specifically two ,loops, are

united. In Fig. 11 for example, there is shown a rib stitch construction wherein knots 9 are pro Straightening out of loop l3. jshowhjin'FigJSis substantially the same as that yfded at certain points both in the depressed ribs32 and'tlie projecting ribs 33.

another 1 and more resistant form of knot con- 'templatedby the "invention 'is shown in Fig. 12. whileknots of this general character maybe forined 'in ayariety'of ways, the knotss'pecifically illustrated may readily be formedby exerting a {lateral "(coursewism pull on'the legs'of the loop of'an eyelet'knot such as the loop 13 f thekn'o't 9 as shown in Fig. 2, causing the eyelet at the "bight end of this loop to straighten out and consequently causing the yarn at the feet of a caught loop suchas the loop 16 to Wrap itself around 'the bight of the loop l3-to form in its turn-the knot 55. As will be'seen'the extent of y-arn embodying'the loop l6 runs from 35 through the loop l 3 as at 36, around the loop it as at '31, through the loop l3a's at '38, and past itself (over the' pbrtion 3-5-'3'6' as exemplified) as at '39. After forming a loop IE it again runs past itself (over theportion 3536) at llljaround the loop 13 at "4'2,-and'through the'lo'cp F3 at 4'3 and outat -44. Ase'xemplified the='por-tions 3'1 and 42 of the yarn run'over the portion '35 thereof at 31a and 420;, and over the portion i' l thereof at 31b and 42b. Even if the extent I3 is not in the form of a loop, the knot is effectively formed around the extent. In either case the extent [6 extends twice about the yarn of the extent l3 (-e. g. at the right) in one direction (e.-g. clockwise as viewed from thelright) and thence'laterally (e. g. to the left at 31 and 42) and twice about the yarnof the extent I3 in the opposite direction '-(e. g. counterclockwise as -viewed from the right) and (preferably and as exemplified in aloop) between the ry'arn'ofthe extent l3 and the laterally extending p'ortions '(31 and 42) of itself.

InFigs. 13-18 are shown successive stages in the transformation'of the knot 9 of Fig. 2 into theknottil of Fig. 12. Inthis method, the legs of a knot-forming loop l3 are spread and are pulled strongly in opposite lateral (coursewise) directions, causing the eyelet to tend to unwrap itself and in so doing to twist the yarn at the feet of the loop I G'to form the knot/50. InFig. 13,

"the initial pull has caused the eyelet to begin to straighten out as shown. The leg portions 31 and 42 of the loop It begin to appear through the bight of the loop [3. In Fig. 14, the bight of :the loop is is shownin the process of being pushed down by they spread of the legs of the loop l3. In Fig. 15, the tension on the bight of the loop I3 is shown as having'pushed the bight still further downwardly. In Fig. 16, the loop [-3 like fabric embodying "in the present instance at each juncture of the --'-'strands a knot 50. A pair of strands I an'd 52 extend vertically twalewise) between the knots oi e'ach'vertically disposed pair of knots 5'0, and "a pair of strands 53 and :54 extend betweeneach hori'Zontally'di's-posed pair of knots 50. This provides not 'only 'anattractiv'e but a, firm-and run-resistant lace fabric, which may be formed with the utmost ease by a simple type 'of knitting procedure. One procedure of this character is exemplified in Fig. which indicates the knitting operation on two strands 55 and '56 in the formation of such afabric. The "strand 55 comprises :knotsB similar to'the knots 'hereinbefore exemplified which are formed from loops l3. The extent 56compris'esloops IBWhich extend through the knots 9. As will :be noted, the portions of the extent 54 which is between the :knots 9 "hasia very considerable amount ofaslack .init. Now, if the portions of the extent-55 which are at each'side of'the-knots 9-are pulled inithe directions indicated by the arrows. as by catching them rat a central point or otherwise and drawing the yarn laterally, the knots Swill convert themselves in knots 50. The formation of these-knots 5!] will require additional yarn at the feet of the loop "I5, which additional yarn will besupplied'by theslack in theportions'of the extent 56 between the .loops. Theseportions are numbered 54 since, when the slack is taken up, they will correspond to the portions 54in Fig. 19.

After the knots 9 have been converted into knots 58, the fabric of Fig. 20 will have automatically transformed itself into the fabric of Fig. 19. The-slack having been taken up, the portions 54 in Fig. 19 Will'appear as'the portions 54 inFig. 18; and the remaining portions of the extent -55the sides of the loops iii-will appear as the portions 5| and '52. The portions of the extent 55 between the knots will appear as portions 53.

As will be seen M53 in Fig. 21, theextent I3 is substantially straight laterally, the-lateral pull having entirely straightened out the loop. The contour of the extent lfi'nevertheless corresponds to that shown inFigs. 12 and 18. As to'the exis shown as having straightened itself out but laterally. In Fig. 17 the legs of the loop 13 are and 42 to press them down over the leg portion of loop l6 and over connector portions and M.

linFig. 18 portions 3'! and have been; pushed down to their final position by the complete '.ofFig. 12,.t'he' only difference" being that the knot "of Fig.12 is tightened and loop 13 isreformed with its legs substantially parallel.

The type'ofknot exemplified in Fig. 12,,how-

fever formed, and whether or not the legsof the knot-forming loop are arranged in" exactly the manner shown," lends itselfto the formation of'a wide variety of desirable types of fabric. One

s h fabricfem'b odying "the invention 5 in certain The condition 65 sho n xerti n es r onth l portion 3 60 tent l3, variations from the looped contour of Fig. 12 to the straight contour of Fig. 18 depend on the type of pulls applied in the transformation of the knot and'thereafter, andthemanner in whichthey are applied. Fig. '21 also shows how a preceding loop 5I-52 is caught between the extents i3 (53' 53) and l6 (5454).

Since certain changes in the above article and in carrying out the above method'and in the constructions set forth, which embody the invention, maybe made Without departing from its scope, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpretedas illustrative and not in a limiting sense;
