Definitions

  • aspects herein relate to a knit component having apertures that are formed by an activatable yarn.
  • Apertures formed in knit components are typically formed through post processing alterations (e.g., cutting) or by modifying the knitting process to create the apertures.
  • WO 2016/105539 A1 describes an easy settable stretch fabric comprising three types of yarns: a rigid fiber, an elastic fiber, and a low-melt fiber.
  • JP H07 305204 A describes the knitted fabric consisting of a cylindrical form having a portion corresponding to a panty, a second portion corresponding to leg and a third portion corresponding to toe.
  • CN 106 521 788 A relates to a medical splint material in flat-knitting structure.
  • the material is woven from low melting synthetic fibers solely, or woven from the low melting synthetic fibers matched with general chemical fibers.
  • CA 1 247 392 A describes the method of production of a double knit fabric for sports garment, namely sweater and hockey includes repeating a pattern of predetermined courses containing wales of consecutive selected groups of tuck and welt stitches to form holes in and throughout the knitted fabric.
  • AT 508 899 A4 describes that in a method for producing a knitted fabric with holes using a single-cylinder circular knitting machine, loops consisting of at least one melt thread are knitted at points to be formed.
  • aspects herein are directed to knit components having one or more apertures formed by an activatable yarn.
  • the activatable yarn responds to a stimulus (such as thermal energy or an aqueous solution) such that the activatable yarn dissipates, dissolves, or melts thereby forming an aperture in the knit component.
  • the aperture is positioned between a first knit course and a second knit course that each comprises a stable yarn type.
  • the yarn type is stable as it does not generally respond to the stimulus by dissipating, dissolving, or melting.
  • the stable yarn type may maintain its structural integrity upon being exposed to the stimulus. That is, if the stable yarn type comprises one or more filaments that are assembled together, this assembly is maintained even after being exposed to the stimulus.
  • the first and second knit courses will remain and form a knit structure surrounding the aperture.
  • an activatable yarn type and a stable yarn type to form the aperture, it allows for quick and efficient manufacturing of apertures in knit components. For example, it may remove any post-processing alterations to the knit component (cutting, seaming, and the like) used to form apertures.
  • forming an aperture using an activatable yarn type removes the increased manufacturing time that is associated with modifying the knitting rotations on, for example, a circular knit machine used to knit the knit component.
  • an aperture is formed in a knit component based on knitting one or more intermediate knit courses with an activatable yarn type where the one or more intermediate knit courses are positioned between the first yarn course and the second yarn course and are interlooped with the first yarn course and the second yarn course.
  • the activatable yarn type may be a fusible yarn type or a dissolvable yarn type.
  • the activatable yarn may extend throughout the intermediate knit course(s) in a course-wise direction.
  • the one or more intermediate knit courses may comprise consecutively knit courses in a wale-wise direction.
  • the stable yarn types of the first knit course (positioned on a first side the aperture-e.g., below the aperture) and the second knit course (positioned on an opposite side of the aperture-e.g., above the aperture) may be interlooped using, for instance, a tuck stitch or a held stitch.
  • the knit component may be exposed to the stimulus.
  • the knit component may be removed from a knit machine and exposed to steam or water.
  • the activatable yarn will then dissipate, leaving behind the aperture.
  • portions of the activatable yarn type may still be present in the knit component.
  • the activatable yarn type may have washed away or may have fused to the surrounding stable yarn types.
  • portions of the activatable yarn type may not have fully dissipated as the knit component may not have been exposed to enough stimulus or not exposed to the stimulus for an adequate amount of time, which would leave portions of the activatable yarn type still present in the knit component.
  • one or more apertures may be formed in the knit component. Specifically, the one or more apertures may be formed in areas once occupied or containing the one or more intermediate knit courses that were knit with the activatable yarn type. As such, the one or more apertures may extend throughout the previously knit intermediate courses in the course-wise direction. Additionally, the one or more apertures may extend in the wale-wise direction, such as in instances where the intermediate knit courses were consecutively knit.
  • the stable yarn type of the first knit course (positioned on the first side of the aperture, e.g., below the aperture) and the second knit course (positioned on the opposite side of the aperture, e.g., above the aperture) may be interlooped using, for instance, a tuck stitch or a held stitch, to form at least in part, for example, a perimeter edge of the aperture.
  • the width of the aperture in the course-wise direction may be defined in part by the interlooping of the stable yarn type of the first knit course and the second knit course.
  • the perimeter edge that defines the aperture may extend through a first, a second, a third, and a fourth area.
  • the first area and the third area of the perimeter edge may be defined by the interlooping (e.g., the tuck or held stitch) of the stable yarn type of the first knit course with the stable yarn type of the second knit course as described above.
  • the second area may be defined in part by one or more knit courses on the first side of the aperture (e.g., below the aperture) being interlooped, while the fourth area may be defined in part by one or more knit courses on the second side (e.g., above the aperture) being interlooped.
  • an activatable yarn type may be described as "dissipating,” “dissipate,” or “dissipated.” These terms generally refer to a change in a physical state of the activatable yarn type such that the yarn strand disintegrates. To describe this differently, the fibers, filament, and/or filaments of the activatable yarn type may have disintegrated or lost their structural integrity either because they melted or were dissolved. In some aspects, all the fibers, filament, or filaments of the activatable yarn type disintegrate based on being exposed to the stimulus.
  • an activatable yarn type examples include a fusible yarn type or a dissolvable yarn type.
  • the term dissipation may be interpreted differently based on whether the activatable yarn type is a fusible yarn type or a dissolvable yarn type.
  • the term "dissipation" with respect to a fusible yarn may refer to fusible yarn melting and/or fusing to the surrounding knit structure.
  • the term dissipating may refer to the activatable yarn type dissolving and being washed away.
  • an activatable yarn type has a lower melting point than a stable yarn type.
  • the activatable yarn type may have a melting point from about 40 degrees Celsius to about 160 degrees Celsius.
  • the melting point of the activatable yarn is from about 60 degrees Celsius to about 110 degrees Celsius.
  • Example activatable yarn types include a polyester yarn such as a 33 decitex polyester yarn and/or a 55 decitex polyester yarn, each having a melting point of about 60 degrees Celsius.
  • Further example activatable yarn types include a polyamide yarn such as a 23 decitex polyamide yarn having a melting point of about 110 degrees Celsius.
  • the term "about" used when, for instance, describing numbers or numerical ranges means within ⁇ 10% of a designated value unless indicated otherwise.
  • the term "dissipation" is not necessarily intended to mean that the activatable yarn type is not present in the knit component.
  • portions of the activatable yarn type may remain in the knit component. This may occur, for example, in aspects where the activatable yarn is a fusible yarn and portions of the fusible yarn fuse to the surrounding knit structure. As such, the activatable yarn type may still be present in the knit component even though it has dissipated. Additionally, portions of the activatable yarn type may still be present if the activatable yarn type was exposed to too little of stimulus or was exposed to the stimulus for too little of time.
  • the activatable yarn type may be a fusible yarn such that it fuses to the surrounding knit structure, which is not illustrated herein.
  • the activatable yarn type is technically present because the fusible yarn may have bonded or fused to surrounding stable yarn types.
  • the term "stimulus” as used herein generally refers to an environmental condition that triggers the activatable yarn type to dissipate. To describe this differently, the physical structure of the fibers, filament, or filaments in the activatable yarn may break down or lose their structural integrity based on being exposed to the stimulus.
  • the stimulus may be any condition, such as an aqueous solution or thermal energy.
  • Example stimuli include water, steam, heat, and the like.
  • stable yarn type refers to yarn types that are dimensionally stable when exposed to the stimulus.
  • yarn types are dimensionally stable if they do not dissipate when exposed to the stimulus.
  • stable yarn types are dimensionally stable because they generally maintain the same filament or fiber count after being exposed to the stimulus.
  • the stable yarn type maintains its structure despite being exposed to the stimulus. It is contemplated that while the stable yarn type may undergo slight changes, such as shrinking or expanding, the overall structural integrity of the stable yarn type is maintained. As such, the stable yarn type does not respond to the stimulus in the same way that the activatable yarn type responds to the stimulus.
  • Example stable yarn types include a polyester yarn, nylon yarn, cotton yarn, or cotton blend yarn having a higher melting point than an activatable yarn type.
  • the stable yarn type may have a melting point from about 180 degrees Celsius to about 300 degrees Celsius.
  • the stable yarn type may have a melting point from about 220 degrees Celsius to about 300 degrees Celsius.
  • the stable yarn type may have a melting point from about 250 degrees Celsius to about 300 degrees Celsius.
  • first state refers to a state of a knit component before it is exposed to a stimulus.
  • second state refers the state of the knit component after it has been exposed to a stimulus.
  • course refers to a predominantly horizontal row of knit loops (in an upright fabric as knit) that are produced by adjacent needles during the same knitting cycle.
  • the knit course may comprise one or more stitch types such as a loop stitch, a held stitch, a float stitch, a tuck stitch, a transfer stitch, and the like as these terms are known in the art of knitting.
  • the term “wale” as used herein is a predominantly vertical column of intermeshed or interlooped knit loops, generally produced by the same needle at successive (but not necessarily all) courses or knitting cycles.
  • horizontal and “vertical” as used herein are relative to an upright fabric as knit in which the heads of knit loops face toward the top of the fabric and the course knit first is oriented toward the bottom of the fabric.
  • held loop may include a loop having legs (or a base) that interloop in a first course and a head that interloops in a second course, wherein one or more intermediary courses are arranged between the first course and the second course. Based on this definition, a held loop is generally created by holding a loop in a needle for one or more intermediary courses in a manner that avoids interlooping with the intermediary courses, before eventually interlooping with a stitch in the second course.
  • tuck stitch as used herein generally refers to a held loop and a tuck loop. The tuck stitch may be created when a needle holding the held loop receives a new yarn segment that passes.
  • the new yarn segment becomes a tuck loop that is included with the needle having the held loop.
  • held stitch generally refers to a held loop and a float loop.
  • the float loop may be created when a needle holding a held loop fails to receive a new yarn segment that passes.
  • plating as used herein means a knit construction where a yarn and one or more plating yarns are knit in the same knit stitch using, for instance, a body yarn feeder and one or more plating yarn feeders. When a particular knit course is described as comprising one or more yarn types, it is contemplated herein that the one or more yarn types are in a plated relationship.
  • integrally knit may mean a textile or fabric having a yarn from one or more knit courses being interlooped with one or more knit courses of another area.
  • a knit course from a first area of a knit component may be integrally knit with a knit course from a second area of the knit component if a yarn from the first area is interlooped with a knit course in the second area.
  • FIGs. 1 and 2 depict a first state and a second state of a knit component 100 depicted in schematic form.
  • FIG. 1 includes a magnified photographic view 136 of a portion of a first area 102 when the knit component 100 is in the first state.
  • FIG. 2 includes a magnified photographic view 138 of the first area 102 when the knit component 100 is in the second state.
  • the knit component 100 further comprises a second area 104.
  • the second area 104 is located between two or more first areas (e.g., 102).
  • the knit component 100 may be any type of knit structure that is knit by a circular or flat-knit machine.
  • the knit component 100 may be any garment, article of footwear, article of headwear, gloves, bag, or the like, that has a knit structure.
  • the knit component 100 can be a knit sock, a knit shirt, or a knit upper.
  • the knit component 100 is integrally knit and forms an entirety of an article. It is also contemplated herein that the knit component 100 may be joined to one or more additional components (knit, woven, nonwoven) to form an article.
  • the first area 102 may comprise a plurality of knit courses.
  • the first area 102 may comprise one or more first knit courses 106, one or more intermediate knit courses 122, and one or more second knit courses 108.

  • the one or more intermediate knit courses may be knit with an activatable yarn type, such as activatable yarn 120. It is contemplated that the one or more first knit courses 106 and the one or more second knit courses 108 may further comprise an activatable yarn type that is plated with the stable yarn type.
  • the one or more first knit courses 106 and the one or more second knit courses 108 may further comprise two stable yarn types, where a first stable yarn type is plated with a second stable yarn type.

  • the first area 1002 may be similar to the first area 102 of knit component 100.
  • the aperture 1010b may have a larger width in the course-wise direction than the aperture 1010a or the aperture 1010c. To describe this differently, the aperture 1010b may extend along a greater number of wales than the aperture 1010a or the aperture 1010c.
  • the spacing in regions 1020a-c may be increased by knitting the interval 1016a further apart from the interval 1016b. This may determine the course-wise length of the knit segments for any of the intermediate knit courses. Described differently, increasing the number intermediary wales in the knit segments between each of one or more intervals 1016a-b may increase the course-wise length of each of the one or more apertures 1010a-c.
  • a first knit segment in the one or more intermediate knit courses may extend through a first number of intermediary wales in regions 1020a, 1020c.
  • a second knit segment in the one or more intermediate knit courses may extend through a second number of intermediary wales in region 1020b.
  • the second number of intermediary wales will generally be greater than the first number of intermediary wales.
  • the activatable yarn in the first number of intermediary wales and second number of intermediary wales will dissipate, thereby forming the aperture 1010b with a greater width than the aperture 1010a or the aperture 1010c.
  • the one or more apertures 1010a-c are spaced apart in the course-wise direction.
  • the number of consecutive wales in each of the intervals 1016a-b may be increased.
  • the number of consecutive tuck stitches (or held stitches) in the intervals 1016a-b may be increased as shown by the presence of four vertical lines in each of the intervals 1016a-b.
  • varying the length of intervals 1016a-b may create a unique aesthetic and different patterns in the first area 1002.
  • it may increase or decrease the amount of ventilation.
  • the length of each interval within the intervals 1016a-b may be varied. In other words, an interval may extend across a greater number of consecutive wales than a different interval.
  • a first area within a knit component may have different configurations than another first area.
  • a knit component may have a first area having larger apertures and a different first area with smaller apertures. This may be advantageous as particular regions of the knit component may require greater ventilation than other regions.
  • a density e.g., the number of apertures or the spacing between the apertures
  • Controlling the density of the apertures for each of the first areas may increase or decrease the ventilation.
