  • the term “sheer fabric-region” includes a fabric -region that is transparent or is at least partially-transparent or mostly-transparent or semi-transparent; such that it covers the body located beneath it, yet it also enables at least some light to pass therethrough, such that a viewer is not entirely blocked from seeing at least some of the body region through the sheer fabric-region, and such that a viewer can see at least some of the body region through the sheer fabric-region; or, a fabric-region that enables passage therethrough of between 25 to 75 percent of incoming light; or, a fabric-region that enables passage therethrough of between 25 to 50 percent of incoming light; or, a fabric -region that enables passage therethrough of between 10 to 75 percent of incoming light; or, a fabric -region that enables passage therethrough of between 10 to 50 percent of incoming light; or, a fabric -region that enables passage therethrough of between 33 to 75 percent of incoming light.
  • High-Count Yarn or “Heavy Yarn” includes, for example, yarn DX 100/4 or yarn having dtex 100 or yarn having dtex 100/4, or yarn having linear density (dtex) 100, or having dtex in the range of 80 to 120, or having dtex of at least 80 or at least 100.
  • Low-Count Yarn or “Fine Yarn” includes, for example, yarn DX 33/1 or yarn having dtex 33 or yarn having dtex 33/1, or yarn having linear density (dtex) 33, or having dtex in the range of 30 to 40 or in the range of 25 to 35, or yarn dtex of up to 40 dtex or up to 33 dtex.
  • the High-Count Yarn (or the Heavy Yarn) has a dtex (linear density) value that is N times the dtex value of the Low-Count yarn (or the Fine Yarn); wherein N is at least 2.
  • N is 2.
  • N is 3.
  • N is 4.
  • N is 5.
  • N is in the range of 2 to 5.
  • N is in the range o 3 to 5.
  • N is in the range of 3 to 4.
  • N is in the range of 3 to 6.
  • the dtex value can be measured as grams per 10,000 meters of yarn.
  • the Applicants have realized that in conventional sock knitting machines, an opaque fabric -region is knitted with a high-count yarn, or with a combination of high-count yarn with low-count yarn; whereas a sheer fabric-region is knitted only with a low-count yarn and without any high-count yarn. [0021] The Applicants have realized that every time that the sock knitting machine needs to knit a sheer fabric -region, the high-count yarn has to be removed from the knitting needle(s), and the low-count yarn (e.g., the “ground” yarn) continues the knitting process.
  • the high-count yarn has to be removed from the knitting needle(s)
  • the low-count yarn e.g., the “ground” yarn
  • the Applicants have further realized that when the same sock knitting machine has to continue knitting another opaque fabric -region of the same sock, the high-count yarn may again get caught in knitting needle(s), which in turn may pull the high-count yarn from the trimming unit or from the yarn-catching unit; and again, because of some physical distance or gap, a “tail” or remainder of 1 to 20 millimeters of heavy-count yarn may remain uncut at the internal side of the sock.
  • the low-count yam or the “ground” yarn is Nylon Drawn Textured Yarn (DTY) 78/48/1, such as in black color; which is threaded in the main feed of the knitting machine via a ceramic tube of yarn finger number 1.
  • the low-count yarn or the “ground” yarn has low elasticity, or has elasticity than is smaller than 150 percent; such that the yarn cannot stretch by more than 50 percent of its original idle length, without breaking or ripping, upon application of a stretching force.
  • the high-count yarn or the “major” yarn is Spandex 78 Dtex single yarn (or Lycra, or Elastane, or other form-fitting or stretchable yarn or a synthetic yarn formed of polyether-polyurea copolymer; having stretching capability of at least 300% or at least 400% or at least 500% upon application of a stretching force relative to its idle length without breaking or without being torn or ripped), which may be covered with (or coated by) Nylon 78/24/2 yarn, such as in red color; which is threaded in color group number 1 of the knitting machine via the ceramic tube of yarn finger number 1; while in the middle, between the yarn’s bobbin to the ceramic tube, this yarn passes through Tensioning Unit, which assists in stretching and releasing the high-count yarn.
  • Spandex 78 Dtex single yarn or Lycra, or Elastane, or other form-fitting or stretchable yarn or a synthetic yarn formed of polyether-polyurea copolymer; having stretching capability of at least 300% or at least
  • FIG. 2 is an illustration of a portion of a modified knitting machine 200, demonstrating a Tensioning Unit 201 (e.g., a temporary yarn tensioning unit, or a temporary yarn stretching unit, or a temporary yarn pulling unit), in accordance with some demonstrative embodiments.
  • a Tensioning Unit 201 e.g., a temporary yarn tensioning unit, or a temporary yarn stretching unit, or a temporary yarn pulling unit
  • the knitting process may be as follows:
  • both the low-count yarn (the fine -count yarn) and the high-count yarn (the heavier count) are knitted together to create the opaque fabric-region or opaque stripe.
  • a blade which is located at the upper head of the machine is stopped from turning or moving, to prevent cutting of the yarn(s); and the head of the knitting machine is raised upwardly, to enable the high-count yarn to move together with the cylinder as it is turning, while the Tensioning Unit 201 allows that yarn to stretch and to withdraw.
  • the yarn finger of the high-count yarn is raised up, to allow it to exit from the knitting needle(s). From this time -point, the knitting machine is able to knit only with the ground / low-count yarn, and it knits the sheer fabric-region or the sheer stripe.
  • the knitting machine knits alternately the opaque fabric-regions and the sheer fabric-regions
  • the blade (or other cutting unit) at the upper side of the knitting machine is not rotating or is not moving, and the head of the knitting machine remains at the upper position.
  • the knitting machine Every time that the knitting machine is about to knit an opaque fabric -region, the yarn finger of the high-count yarn is lowered or descends downwardly, and the knitting needles catch it and engage with it.
  • the knitting machine is about to knit the sheer fabric-region, the yarn finger of the high-count yarn is moved upwardly and rises up to exit the knitting needles. The knitting process repeats with alternative iterations, knitting opaque fabricregions and sheer fabric-regions in the alternate.
  • FIG. 3 is an illustration of a portion of a modified knitting machine 300, in accordance with some demonstrative embodiments. It indicates the upper head of the knitting machine; the blade; and the high-count (or heavy-count) yarn.
  • the opaque fabric -region (611) is formed of a yarn that contains Polyethylene. In some embodiments, the sheer fabric-region (612) lacks any Polyethylene.
  • the sock (610, 620, 630) is a non-stocking non-lingerie clothing article, that is formed exclusively of yarns knitted at a gauge that is not more than 16.
  • opaque fabric-regions (611) and sheer fabric-regions (612) are alternating horizontally and not vertically, and have tails-free connection regions (613, 614).
  • opaque fabric -regions (611) and sheer fabric-regions (612) are alternating vertically and not horizontally, and have tails-free connection regions (613, 614).
  • opaque fabric -regions (611) and sheer fabric-regions (612) are alternating both vertically and horizontally, and have tails-free connection regions (613, 614).
  • Some embodiments include a sock that was produced by said production system.
