Definitions

  • This invention relates generally to knitted elastic garments and a method of forming the same and more particularly to garments that are knit of cellulosic yarn, such as cotton, the knit garments having substantially elastic properties which make them adaptable to fit a wide range of body sizes.
  • garments which are knit of cotton yarn normally have a greater amount of stretchability than garments which are formed of woven cotton yarn
  • conventional types of knitted cotton garments do not have enough stretchability to fit a wide range of body sizes and the knitted cotton garments of the ordinary type do not have the ability to quickly return after stretching.
  • Knit garments having elastic properties have also been formed of composite yarns in which cotton fibers are blended with a stretchable core yarn which is formed of a texturized and heat-set synthetic yarn.
  • This type of composite yarn usually has a small percentage of cotton fibers and all of the elasticity is obtained from the stretchable synthetic core yarn.
  • It is a more specific object of the present invention to provide a method of forming knitted elastic cotton garments which includes knitting the garments oversize by forming very large loose or elongated stitch loops from a cotton yarn, then treating the garments in a solution of caustic soda without any tension on the garments to swell and shrink the cotton yarn and to reduce the size of the garment to its normal size, washing the garments to remove the caustic soda solution, and then finishing the garments in the usual manner, such as dyeing and boardmg.
  • FIGURE 1 is a side elevation of a stocking of the halfhose type which has been knit oversize with very loose or greatly elongated stitch loops, the normal toe opening having been closed by a suitable seam;
  • FIGURE 2 is a greatly enlarged view of the knit stitch loops in the area of the foot enclosed by the circle indicated at 2 in FIGURE 1;
  • FIGURE 3 is a view similar to FIGURE 1 and illustrating the reduction in size of the half hose after it has been subjected to the caustic treatment;
  • FIGURE 4 is a greatly enlarged view of the knit stitch loops in the area enclosed by the circle indicated at 4 in FIGURE 3 and illustrating the swelling of the yarn and the reduction in size of the stitch loops after the halfhose has been subjected to the caustic treatment;
  • FIGURE 5 is a front elevation of a full-fashioned ladies panty which has been knit oversize with very loose or greatly elongated stitch loops;
  • FIGURE 6 is a view similar to FIGURE 5 to illustrate the reduction in size of the panty after it has been subjected to the caustic treatment;
  • FIGURE 7 is a front elevation of a ladies seamless girdle which has been knit oversize with very loose or greatly elongated stitch loops;
  • FIGURE 8 is a view similar to FIGURE 7 to illustrate the reduction in size of the ladies seamless girdle after it has been subjected to the caustic treatment.
  • the present knitted elastic cotton garments are shaped to the desired configuration during the knitting operation, however, the garments are formed of very loose or greatly elongated stitch loops to form an oversized garment. After knitting, the garments have an unfinished appearance and the stitch loops are so large that it is not acceptable as a practical garment to be worn in this state. During the knitting operation the stitch loops are formed approximately 25 to 60% longer than normal so that the garments will be approximately 25 to 65% larger than the desired size when the garments are ready for wear.
  • the oversize garment is then placed in an untensioned condition in a solution of caustic soda to swell the cotton yarn and shrink the garment to thereby reduce the overall size of the garment. Since the caustic treatment causes the cotton yarn to swell and shrink, the stitch loops are also reduced in size and the yarns increase in diameter to make the knit fabric much more dense or compact. Then, the garment is washed to remove the caustic solution and the garment may be finished by dyeing and boarding, when necessary.
  • the finished garment is stretchable in both the walewise and coursewise directions, and it has sufiicient elastic properties that it will immediately return to substantially its original unstretched dimension.
  • This feature makes the garments highly desirable since they easily conform to the body of the wearer and permit freedom of movement by the wearer while retaining the comfortable feel and absorptive quality of garments made entirely of cotton.
  • the invention is generally directed to knitted cotton garments of the type which are shaped during the knitting operation and normally worn next to the body, such as hosiery, ladies full-fashioned panties, ladies seamless girdles, brassieres, bathing suits, and the like, it is not intended to be limited to these particular garments.
  • Example I Referring particularly to FIGURES 1-4, there is shown a mans half-hose 10 which has been knit on a Komet type circular knitting machine having a 3% inch needle cylinder and 132 needles. As is well known, this type of knitting machine has axially alined upper and lower needle cylinders and double-ended latch needles which may be selectively operated in either of the cylinders to produce both plain and rib fabrics.
  • the half-hose 10 is knit from the top to the toe in the conventional manner'except that the needles are drawn to a greater than normal depth to form very loose stitches and an oversized stocking.
  • Two ends of 30/1 Supima cotton yarn having a standard soft knitting twist of 14 /2 turns per inch are fed to the needles through the same yarn feeder finger while a covered strand of rubber yarn is also fed to the needles to form a conventional make-up at the upper edge of the top or cuff 11.
  • a few courses, are then knit in what may be termed a one-by-one rib arrangement with the covered rubber yarn inlaid in every other course of the fabric and the remaining courses of the cuff 11 are formed by knitting a two-by-two rib pattern while continuing to inlay the covered rubber yarn in every other course.
  • alternate pairs of adja cent needles operate in the lower cylinder and intervening pairs of adjacent needles operate in the upper cylinder.
  • the covered rubber'yarn is removed and a different rib pattern is formed.
  • a nine-by-four rib pattern is formed with the plain rib extending up the back of the leg of the stocking containing eleven wales to account for the 132 needles in the cylinder.
  • the heel pocket is knit in a conventional manner by first knitting on approximately half of the needles while reciprocating the needle cylinder in a narrowing operation and then in a widening operation to form the usual narrowed and widened gussets of the heel pocket.
  • the nylon reinforclng yarn is removed and the two ends of 30/1 Supima cotton yarn are again fed to all the needles while the needle cylinder is rotated to knit the foot 14.
  • the sole or lower portion of the foot 14a is plain while the upper or instep portion 14b includes the nine-byfour rib pattern.
  • the toe 15 is knit with the 40 denier nylon filament yarn and the three ends of 30/1 Supima cotton yarn again being fed to the needles in plated relationship.
  • the thus formed stocking blank usually has an opening extending across the upper part of the foot and a suitable number of loopers rounds, not shown. The loopers rounds are removed during the closing of the toe of the stocking blank by either a sewing or looping operation to form a toe closure seam, indicated at 16 in FiGURE 1.
  • the stockings are then placed in a solution containing 16% caustic soda (NaOH) for ten minutes.
  • the caustic solution is preferably at room temperature and the stockings are not under any tension while being treated.
  • the caustic soda solution may be agitated during the treatment period to insure uniform treatment. After the shrinking and swelling of the stockings in the caustic soda solution, they are washed until all of the caustic soda solution is removed and then the stockings may be dyed to the desired shade or color.
  • the stockings be knit in two sizes which may be termed small and large and these two sizes will fit men that wear sizes 10 through 13.
  • the small size stockings are boarded on a size 9 /2 boarding form and the large size stockings are boarded on a size 11 boarding form.
  • the stockings are stretched only a small amount on the boarding form so that the heat applied during the boarding operation will not affect the stretchability and high degree of recoverability in the finished stockings.
  • the stockings are finished on a boarding machine of the type which has flat forms that move through a heating chamber and the stockings are automatically stripped from the forms as they come out of the heating chamber.
  • the stockings After the stockings are boarded, they have sufficient stretch to comfortably fit several foot sizes. For example, the small size stockings will fit foot sizes 9 /2 through 11 and the large size stockings will fit foot sizes 11 through 13.
  • the manner in which the yarn swells and shrinks and the manner in which the stitch loops are reduced is best shown in FIGURES 2 and 4. Since the yarn itself swells and shrinks, the stitch loops are re prised in both coursewise and walewise directions with a slightly greater amount'of reduction occurring in the walewise direction.
  • the amount of shrinkage and stretchability of the knit stockings are subject to variations in the construction of the stockings, the strength of the caustic soda solution, the temperature of the caustic soda solution, the amount of twist in the yarns, the construction of the yarns, etc.
  • the stockings should be initially knit about'60% larger than the desired finished size and they will stretch on the order of 45% after they are finished.
  • Example 11 Referring particularly to FIGURES 5 and 6, there is shown a ladies full-fashioned panty which is knit of cotton yarn and in generally the manner disclosed in the United States patent to Garrou et al., No. 2,796,389, and issued April 19, 1955.
  • the full-fashioned panty blank is knit on a full-fashioned knitting machine and is suitably fashioned during knitting so that when the fashioned front and rear panels 21 and 22 are joined together by side seams 23 and 24, the leg openings 25 and 26 are formed and the panty generally conforms to that portion of the body on which it is to be worn.
  • the panty blank is knit throughout of a /1 Supima cotton yarn having the standard soft knitting twist and it is fashioned during the knitting operation in the same general manner as that set forth in the said Garrou et 211. patent.
  • the fashioning marks adjacent opposite sides of the panty are indicated at 27 and 28 in FIGURES 5 and 6.
  • an elastic band 29 may be stitched around the upper end of the panty and elastic bands 25a and 26a may be stitched around the respective leg openings 25 and 26.
  • the machine is adjusted to draw greatly elongated stitch loops and form an oversized garment blank, from which the oversized panty is formed, as illustrated in FIGURE 5. It is to be noted that no special attachments are required to knit the panty blank and the usual widening and narrowing operations are performed in the conventional manner.
  • the oversized panties as shown in FIGURE 5, are then treated in the same manner and in the same caustic soda solution as described in Example I.
  • This caustic soda treatment swells and shrinks the cotton yarn and also reduces the elongated stitch loops to reduce the size of the panty, as shown in FIGURE 6.
  • the caustic soda solution is then removed by washing the panties and they may then be 'dyed and boarded.
  • the panty blanks be knit in two sizes and then the resulting elastic panties will stretch to comfortably fit a Wide range of body sizes.
  • the elastic bands 29, 25a and 26a be attached to the panties before they are treated in the caustic soda solution, it is to be understood that they could be attached after the shrinking process, if desired.
  • Example III Referring particularly to FIGURES 7 and 8, there is shown a ladies seamless girdle which is knit of cotton yarn and in generally the manner disclosed in the United States patent to Garrou et al., No. 2,962,884, and issued December 6, 1960. Asis clearly set forth in said Garrou et al. patent, the seamless girdle is fashioned or shaped during knitting so that it generally conforms to the shape of that portion of the body on which it is to be worn.
  • the seamless girdle includes a first seamless leg 30, a generally narrowed extension 31, a widened and narrowed front gusset 32 and a similar rear gusset, not shown, a generally widened extension 33, and a second seamless leg 34.
  • the lower portions of the inner edges of the extensions 31 and 33 are joined together along a suture line 35 and their upper portions are joined to the opposite edges of the front gusset along respective suture lines 36 and 37.
  • the various portions of the seamless girdle are joined together during the knitting operation and the upper end of the girdle blank is then slit to form a waist opening in the manner clearly set forth in said Garrou et al. patent.
  • the girdle is knit throughout of a 30/1 Supima cotton yarn having the standard soft knitting twist and the stitch loops are drawn much longer or larger than the normal size stitch loops to produce an oversized garment blank, from which the oversized girdle is formed, as illustrated.
  • the waist opening is formed by slitting the upper portion and then sewing an elastic band 38 thereto. It is preferred that the lower ends of the legs 30 and 34 have turned hems that are formed during the knitting operation.
  • the oversized girdles, as shown in FIGURE 7, are then treated in the same manner and in the same caustic soda 6 solution as described in Example I.
  • This caustic soda treatment swells and shrinks the cotton yarn and also reduces the elongated stitch loops to reduce the size of the girdle, as shown in FIGURE 8.
  • the caustic soda solution is then removed by washing the girdles and they may then be dyed and boarded.
  • the seamless girdle blanks be knit in two sizes and then the resulting elastic girdles will stretch to comfortably fit a wide range of body sizes.
  • the elastic band 38 be attached to the girdles before they are treated in the caustic soda solution, it is to be understood that it could be attached after the shrinking process, if desired.
  • Both the full-fashioned panty described in Example II and the seamless girdle described in Example III are initially knit approximately 60% larger than their size after the shrinking takes place in the caustic soda solution. However, this is dependent upon the amount of shrinkage which takes place in a particular caustic soda treatment and the size of the knit garment may be varied so that the shrunk garment will be the desired size. While yarn formed entirely of cotton fibers is described in each of the examples, it is to be understood that small percentages of other types of fibers may be blended with the cotton fibers before the yarn is formed.
  • a large number of dif ferent sizes of cotton yarns having varying amounts of twist are required to knit all the various types of stockings for children, ladies and men.
  • sizes of cotton yarns used in knitting hosiery are from about 4/ 1 to 40/1 and from about 10/2 to /2, the twist ranging from about 10 to 20 turns per inch.
  • the cotton yarn used to form the elastic knitted garments of the present invention may be combed, carded or mercerized yarns which may be either dyed or undyed.
  • each of the garments described has been found to have a maximum stretchability of about 45%.
  • the amount of stretchability is at least in part dependent upon the amount that the garments are shrunk by the caustic soda solution and therefore the amount of stretchability can also be varied by making the desired changes in the caustic soda treatment. It is preferred that the stretchability of the elastic knitted garments be within the range of about 25 to 45.
  • a method of producing a knitted elastic garment shaped to generally conform to the configuration of that portion of the body on which the garment is to be worn and having the appearance of a conventional non-elastic garment having normal size stitches comprising the steps of (a) knitting a yarn consisting mainly of caustic shrinkable cellulose while forming a fabric having longer than normal stitch loops into an oversized blank, and
  • a method according to claim 1 wherein the knitted stitch loops before treating are about 25 to 60% longer than normal stitch loops.
  • a method of producing a knitted elastic stocking shaped to generally conform to the configuration of the human foot and leg on which the stocking is to be worn and having the appearance of a conventional non-elastic stocking having normal size stitches comprising the steps of (a) knitting a yarn consisting mainly of caustic shrinkable cellulose while forming a fabric having longer than normal stitch loops into an oversized stocking blank having heel and toe pockets therein, and
