  • At least one object of the invention in accordance with at least one embodiment thereof, provides an underwear including a plurality of portions assembled in a fashion where stiches are not aligned with a sciatic nerve of a wearer when worn by a wearer.
  • At least one object of the invention in accordance with at least one embodiment thereof, provides a no-melt no-drip underwear comprising a front portion, the front portion including a pair of side fabric portions secured on lateral sides of a middle fabric portion, the pair of side fabric portions including warps generally aligned in a longitudinal direction of the underwear and welfs generally disposed at an angle from the warps allowing the fabric to stretch in a transversal direction, and a rear portion, opposed to the front portion, the rear portion including a pair of side fabric portions secured on lateral sides of a center fabric portion, the pair of side fabric portions including warps generally aligned in a longitudinal direction of the underwear and welfs generally disposed at an angle from the warps allowing the fabric to stretch in a transversal direction, the center fabric portion including fabric comprising warps generally aligned in the transversal direction of the underwear and welfs generally disposed at an angle from the warps allowing the center fabric portion to stretch in the longitudinal direction
  • At least one object of the invention in accordance with at least one embodiment thereof, provides a fire-resistant underwear comprising fabric devoid of polymer, the fabric being woven with a weaving including at least two distinct sets of interlaced yarns capable of temporarily stretching in one direction when tension is applied to the fabric in the at least one direction, the fabric recovering its original size when tension thereon is released, the underwear further comprising a rear portion including a pair of side fabric portions disposed on lateral sides of a center fabric portion, the center fabric portion including longitudinal stretching capability, wherein the fabric includes no-melt no-drip heat-resistant material and wherein the stretching property of the fabric is mechanically provided by the weaving thereof, whereby the center fabric portion is adapted to longitudinally stretch when a wearer is bending forward to cover a wearer's lower back.
  • Each of the embodiments of the present invention has at least one of the above-mentioned objects and/or aspects, but does not necessarily have all of them. It should be understood that some aspects of the present invention that have resulted from attempting to attain the above-mentioned objects may not satisfy these objects and/or may satisfy other objects not specifically recited herein.
  • FIG. 1 is a schematic illustration of a front portion of an underwear in accordance with an embodiment of the invention
  • FIG. 2 is a schematic illustration of a rear portion of an underwear in accordance with an embodiment of the invention
  • FIG. 3 is a schematic illustration of a front portion of an underwear in accordance with an embodiment of the invention.
  • FIG. 4 is a schematic illustration of a rear portion of an underwear in accordance with an embodiment of the invention.
  • FIG. 5 is a schematic illustration of a fabric knitting in accordance with an embodiment of the invention.
  • the underwear exemplified in FIG. 1 throughout FIG. 4 is made of fabric that has at least one of following properties: heat resistance, flame resistance, drip resistance and melt resistance, combined with mechanical stretching capabilities.
  • the fabric is free of synthetic material that cannot sustain heat, or flames, that melts and/or drips.
  • synthetic materials are providing stretching capabilities to heat, flames, melt and drip resistant fabrics. Heat, flames, melt and drip resistant fabrics are therefore not elastic by nature and the lack of stretching results in a stiffer material. Heat resistance is going to be used below to ease readability of the text and is not disclaiming flame resistance, drip resistance and melt resistance by any means.
  • Fabrics are generally woven or knitted with interlaced sets of yarns. At least two sets of yarns are interlaced at right angle thereof. A first set of parallel yarns is called warp. The warps are not significantly stretching in their longitudinal direction. Conversely, a second set of yarns is called welf and is generally interlaced at right angle from the first set of yarns, the warp. The welf allows stretching in its knitting direction if it uses a knitting pattern that allows stretching thereof. The resulting material is thus stretchable in the longitudinal welf direction.
  • Other types of weaving like felting, braiding and plaiting are encompassed by the present application despite the text of the specification is directed to weaving without disclaimer to ease its readability.
  • the underwear 10 is made of fabric 14 material and includes a hips portion 18 , a middle portion 22 and two side portions 26 .
  • the side portions 26 includes fabric having the warp yarns 30 in the longitudinal direction 34 of the underwear 10 .
  • the welf yarns 38 are generally disposed at an angle from the warp yarn 30 , generally orthogonal to the warp yarn 30 , and allows the fabric 14 to stretch in the transversal direction 42 . Stretch direction is illustrated with arrows 46 .
  • the two side portions 26 are interconnected with the middle portion 22 with a joint 28 that could be embodied as a seam.
  • FIG. 2 illustrates a rear portion 50 of the underwear 10 of FIG. 1 .
  • the underwear 10 includes a center portion 54 generally extending over most of the rear portion of the underwear.
  • the center portion 54 including fabric having the warp yarns 30 in the transversal direction 42 of the underwear 10 .
  • the welf yarns 38 are generally disposed at an angle from the warp yarn 30 and allows the fabric 14 to stretch in the longitudinal direction 34 .
  • the center portion 54 of the rear portion 50 of the underwear 10 is hence allowing the underwear 10 to stretch when a wearer of the underwear 10 is bending over in a forward direction and prevent exposing a portion of skin. Stretch direction is illustrated with triangular arrows 46 .
  • the warp 30 and the welf 38 of the two side portions 26 are disposed in opposite arrangement with the center portion 54 to allow material stretching in opposite directions and improve the comfort provided by the underwear 10 by adjusting to movements of a wearer, even if the underwear 10 is worn close to the skin hence reacting to all movements of the body of a wearer.
  • the two side portions 26 are interconnected with the middle portion 54 with a joint 28 that could be embodied, here again, as a seam.
  • the middle portion 54 includes sort of a “V” shape distally beginning in the region of the hips of a wearer at its upper portion thereof and proximally ending between the legs of a wearer at its lower portion thereof.
  • the joint 28 between the middle portion 54 and the side portions 26 is located in such a way to intersect a sciatic nerve 58 of a wearer when worn by the wearer to prevent uncomfortable, and even painful, interaction thereof.
  • a sciatic nerve 58 of a wearer when worn by the wearer to prevent uncomfortable, and even painful, interaction thereof.
  • the underwear 10 assembled in such a manner allows front transversal 42 stretching over the legs and back longitudinal 34 stretching using different yarn orientations for different portions of the underwear 10 to cooperate with the underwear stretching when adapting to movements of a wearer.
  • This underwear 10 construction allows rear longitudinal stretching over the upper butt and lower back when a wearer bends forward to prevent uncovering lower back skin.
  • the warp 30 and the welf 38 of the two side portions 26 are disposed in a similar arrangement than the underwear 10 embodied in FIG. 1 and FIG. 2 .
  • the middle portion 54 includes sort of a “U” shape distally beginning in the region of the hips at its upper portion thereof and proximally ending between the legs at its lower portion thereof.
  • the joint 28 between the middle portion 54 and the side portions 26 is located in such a way to intersect the sciatic nerve 58 , at about 90 degrees, when worn by a wearer to prevent uncomfortable and even painful interaction thereof.
  • there is only a punctual overlapping and no lengthy or parallel overlapping of the the joint 28 with the sciatic nerve 58 when worn by a wearer.
  • FIG. 5 illustrates an exemplary knitting 66 with knitting 66 exemplified, without being limited to, with a series of warps 30 and a series of welf 38 .
  • knitting 66 can be made without the warps 30 in an alternate embodiment without departing from the scope of the present invention.
  • the knitted piece of fabric has a stretching direction 70 and a non-stretching direction 74 to manufacture a non-isotropic fabric. If knitting does not include warps 30 , some stretching can be obtained in the orthogonal direction 78 to manufacture an isotropic fabric without departing from the scope of the invention.
