Definitions

  • This invention relates to knitted fabric and, more especially, to an improved resilient, yieldable or stretchable fabric having variegated ornamental areas therein, and the method of producing same.
  • a knitted fabric such as mens or ladies hose
  • nylon which is a synthetic linear condensation polyamide, or a synthetic polymeric amide yarn
  • Dacron which is a synthetic linear condensation polyester yarn.
  • a second strand treated in the same manner as the first strand, but twisted in the opposite direction, is loosely intertwisted with the first strand to form the yarn and a plurality of such yarns, dyed difierent colors, are then knitted to form separate areas of the knitted article, wherein junctures of adjacent areas are interknitted thereby obviating the necessity of dyeing the article after/it is knitted, to produce an article which is stretchable or yieldable and which also has a plurality of different colored areas formed therein.
  • Figure 2 is an enlarged elevation of the upper portion of a stocking similar to that shown in Figure 1, but wherein the ornamental areas are formed as an Argyle pattern.
  • the stocking shown in Figure 1 is broadly designated at It and the stocking shown in Figure 2 is broadly designated at ll.
  • Each of the stockings I0 and II includes a top or welt l2, an ornamental area or leg portion broadly designated at l3, a heel or heel pocket 14, a foot l5 and a toe pocket I6.
  • the toe pocket I6 is omitted from the illustration in Figure 2.
  • the top or welt I2
  • the heel pocket 14, the foot l5 and the toe pocket N5 of the stocking l are shown as being knit from a solid colored yarn, which may be termed a body yarn, and portions of the leg or ornamental portion [3 of the stocking H3 are also shown as being knit from the solid colored yarn.
  • the leg [3 of the stocking ID has a plurality of vertical stripes or narrow ornamental areas thereon indicated at l3a to l3 inclusive, which are knitted from different colored yarns and wherein each area may be a different color from the others.
  • the areas l3a, I30 and l3e are shown as being knitted from a red yarn and the areas [3b, 13d and l3f are shown as being knitted from a blue yarn. It is evident that both sides of the stocking lil'in Figure 1 may be identical.
  • areas 139 and l3h are knitted from the body yarn between the areas 13b, I30, I3d and 136.
  • the top 12, the heelpocket i4 and foot [5 of the stocking l I are also knitted from a body yarn which may be white and the leg 13 thereof has variegated diamond-shaped or gusset-shaped areas therein indicated at 25, 26, 21, and 28, each of which is knitted from a difierent colored yarn and which differs in color from the body yarn.
  • the areas and 28 are shown as being knitted from a blue yarn and the areas 26 and 21 are shown as being knitted from a red yarn.
  • a gusset 3D is knitted between the upper portions of the areas 25 and 26 and a diamond 3
  • a lower gusset 32 is also knitted between the lower portions of the areas 2! and 28.
  • and 32 are also shown as being knit from a white yarn or from the body yarn in Figure 2.
  • the junctures of the adjacent areas extend at an angle relative to the wales and courses, and, it is evident that these areas may be interknitted at their junctures for one or more wales.
  • one muIti-filament strand of polyamidi'c or polyester yarn is twisted a plurality of turns in one direction, after which the yarn is pre-set, then the yarn is dyed under the necessary high temperature and pressure, then additional twists in the same direction are imparted to the yarn, then the yarn is again set after which it is pre-shrunk. Then, if desired,
  • additional twists may be imparted to the yarn in the same direction up to the total number of turns or twists desired. If additional twists are added, the yarn is then set and dried. The yarn is then untwisted or twisted in a reverse direction back to the point zero, or beyond. A strand of yarn, thus treated, is then twisted with a yarn treated in a similar manner, but twisted in the opposite direction and the yarn, thus treated, may be formed into various types of articles, as desired, and further dyeing or processing is not necessary.
  • the amount of twist necessary to produce the supertwist depends upon the denier of the yarn and also upon the effect desired, as more or less curl is sought. For example, twenty to forty denier yarn is usually twisted as high as a total of one hundred turns per inch, while forty to one hundred denier yarn is only twisted as high as fifty turns. If heavier than one hundred denier yarn is used according to this process, the amount of twist imparted thereto should be somewhat less than fifty turns.
  • the invention is not limited to any particular type of dye and the whole range of dyes having affinity for the particular polyamide or polyester being twisted, may be used.
  • the following dyes are suitable:
  • nylon can be dyed with almost any type of dye and the above examples are listed by way of illustration only.
  • Acetamine Yellow'N (no prototype or color index no.)
  • vat pigments neutral, chrome, direct and acid colors may be utilized according to well known processes in practicing this invention.
  • Example each The yarn is then rewound on perforated metal dye tubes and is dyed at temperatures between 180 degrees and 300 degrees Fahrenheit preferably around 240 to 265 degrees-Fahrenheit and under super-atmospheric pressure.
  • the yarn is dried after the dyeing operation and is rewound onto bobbins and an additional 25 turns of twist per inch are imparted thereto to the right, or the same direction in which the first turns of twist were imparted.
  • the yarn is then given a second setting by subjecting the same to steam for three periods of approximately one and one-half hours each.
  • the yarn on the bobbins is then placed in a preboarding machine and is subjected to wet steam or water for a period of approximately one hour at temperatures from 250 degrees Fahrenheit to 270 degrees Fahrenheit at pressure of from 22 to 28 pounds. This is a pre-shrinking operation which causes the yarn to shrink.
  • the yarn is then dried at a temperature of from 150 degrees Fahrenheit to 170 degrees Fahrenheit for a period of 12 hours, or until dry. After the yarn is dry, any additional twist which is desired is added to the right, or in the same direction up to a total number of turns of twist approximately 100 turns per inch depending upon the denier. In using 70 denier yarn, no additional twist is necessary.
  • the yarn is set an additional time by subjecting the same to steam for three periods approximating one and one-half hours each.
  • the yarn is then twisted in the opposite direction, or untwisted with the total number of turns which have been imparted thereto. In this in stance, the yarn is twisted back to the left up to 100 turns per inch, or to the point zero. If desired, the twist may go back slightly beyond the point zero to give some additional twist to the yarn.
  • a second '70 denier, multi-filament nylon yarn is treated in an identical manner, except that the twist imparted thereto is to the left or opposite to the direction in which the twist is imparted to the first nylon yarn.
  • These two yarns are then twisted or plied together at approximately two turns per inch to form a single multiply strand and the yarn thus formed may be knitted or woven into articles of various types and no additional dyeing or treating is necessary.
  • the yarn is preferably wound on perforated metal dye tubes in order to facilitate the dyeing thereof.
  • the yarn in loose condition is subjected to steam for a period of approximately one and onehalf hours, after which there is a short lag period, during which time the yarn will tend to dry out and then it is again subjected to steam for two additional periods approximating one and onehalf hours each with a lag period therebetween.
  • This setting is preferably done in a regular conditioning box or twist setter, such the H. W. Conditioner manufactured by Industrial Drier Corporation.
  • the pre-shrinking operation under high temperature, shrinks yarn and the yarn on collapsible bobbins is placed in a conventional preboarding machine and is subjected to wet steam or water.
  • the pre-shrinking time is preferably one hour at 265 degrees Fahrenheit and 25 pounds pressure for nylon, but may vary between 250. degrees Fahrenheit and 270 degrees and the pressure may vary between 22 and 28 pounds. If desired, the yarn may be in loose form when pre-shrunk.
  • dry heat is used which is preferably accomplished by placing the yarns in a drying room equipped with a heater and an exhaust fan. Apparently, approximately 12 hours is the minimum time necessary to dry the yarns, but a different amount of time, more or less, is not harmful provided the yarn is thoroughly dried.
  • the preferred temperature is degrees Fahrenheit for nylon and Dacron and may range between 150 degrees and degrees Fahrenheit.
  • an article such as a stocking or the like may be provided with ornamental areas and also be stretchable or yieldable.
  • That method of knitting a stretchable multi-colored fabric of multi-filament polyamidic and polyester yarns of from 20 to 100 denier which comprises twisting one of said yarns at least 5 turns per inch in one direction, setting the twisted yarn, dyeing the yarn, twisting the yarn an additional plurality of turns per inch in the same direction to provide a total twist of from 40 to 100 turns per inch, setting and preshrinking the yarn, and untwisting the yarn to substantially zero twist, then repeating the above operation on a second of said yarns by applying reverse twist thereto, then twisting the two yarns together to form a composite yarn, then knitting some areas of said fabric with said composite 7 yarn; andknitting otherareas of said fabric with composite yarns treated in a like manner but dyed a different color.
  • That method of forming a stretchable multi-colored fabric of multi-filament polyamidic and polyester yarns of from 20 to 100 denier which comprises imparting from 20 to 30 turns of twist thereto in one direction to a first of said yarns, setting the yarn, dyeing the yarn in its twisted state, imparting 20 to 30 turns of additional twist thereto in the'same direction as before, setting, and pre-shrinking the yarn, then imparting additional turns of twist thereto in the same direction as before to provide a total twist not exceeding 100 turns per inch, setting the yarn, then untwisting the yarn a number of turns substantially equal to the total number of turns imparted thereto, then treating a second of said yarns as above outlined but imparting the twists in the opposite direction from that imparted to the first yarn, then plying the two yarns together at a relatively low twist to form a composite yarn, then knitting some areas of said fabric with said composite yarn and knitting other areas of said fabric with composite yarns treated in a like manner but dyed a different color.
  • a method for producing a stretchable multicolored stocking of polyamidic and polyester yarns having permanent crimping and fluffing properties which consists in highly twisting one of said yarns, setting said yarn, dyeing said yarn in twisted state at a high temperature and at superatmospheric pressure, additionally highly twisting said yarn, setting said yarn, shrinking said yarn and then back twisting the yarn to substantially zero twist, then treating a second of said yarns in a like manner but twisting the second of said yarns in an opposite direction, then plying the two yarns together at'a relatively low twist to form a compositeyarn, then knitting the body portion of said stocking'with said com- .posite yarn and knitting certain areas of said stocking with other compositeyarns treated in a like manner but dyed a different color.
  • a process of knitting a stretchable multicolored stocking of synthetic multi-filament polyamidic and polyester yarns consisting in separately supertwisting two of said multi-filament yarns in opposite directions, subjecting the twisted yarns to heat to set the same, dyeing said yarns in twisted state at high temperature at superatmospheric pressure, further supertwisting the yarns in their respective original directions, again subjecting them to heat to set the same, shrinking said yarns, untwisting the two yarns to a substantially, zero twist, twisting the two yarns together in a relatively low twist, thereby producing a multiple strand dyed yarn with latentcrimp eiiecting physical properties, then knitting a portion of a stocking with said multiple strand dyed yarn and knitting other portions of said stocking with other multiple strand dyed yarns treated in the same manner but dyed a different color'and interknitting adjacent edges of adjacent areas together.
  • That method of knitting stretchable argyle socks utilizing multi-filament polyamidic and polyester yarns of from 20 to 100 denier which comprises twisting one of said yarns at least 5 turns per inch in one direction, setting the yarn, dyeing the yarn under high temperature and pressure, twisting the yarn an additional plurality of turns per inch in the same direction as before to provide a total twist of from 40 to 100 turns per inch, then setting and pre-shrinking the yarn, then untwisting the yarn a number of turns perinch approximating the total number of turns per inch which has previously been applied thereto, then repeating the operation on a second of said yarns but twisting the second of said yarns in the opposite direction, then plying the two yarns together at a relatively low twist to form a composite dyed yarn, then knitting the body portion of a' sock with said composite yarn and knitting a plurality of diamond-shaped areas in said sock of other composite dyed yarns treated in a likemanner but dyed different colors and interknitting adjacent edges of adjacent
