Definitions

  • the present invention relates to brassieres. More particularly, the present invention relates methods of making cotton blend glue brassieres. Such brassieres include a finished edge that does not require separate binding or narrow edge finishing.
  • the method includes inserting an adhesive layer between a first fabric layer and a second fabric layer to form a fabric sub- assembly.
  • the sub-assembly has a periphery that is larger than an outer periphery of the undergarment .
  • the method further includes causing the adhesive layer to form a laminate from the sub-assembly and removing a trim from the laminate at the outer periphery to form a finished edge of the undergarment.
  • the first and second fabric layers include at least one cotton material .
  • a method including applying an adhesive layer to a first fabric layer; overlying the adhesive layer with a second fabric layer; causing the adhesive layer to bond the first and second fabric layers together to form a stretchable laminate; and cutting the stretchable laminate along the outer periphery to form a finished edge of the undergarment that resists unraveling.
  • the stretchable laminate has a periphery that is larger than an outer periphery of the undergarment.
  • the first fabric layer is a first cotton blend fabric and the second fabric layer is a second cotton blend fabric.
  • a method including forming an adhesive layer having an adhesive-free portion; surrounding the adhesive layer with a first fabric layer and a second fabric layer; causing the adhesive layer to bond the first and second fabric layers together to form a stretchable laminate; and cutting stretchable the laminate along the outer periphery to form a finished edge of the undergarment that resists unraveling.
  • the adhesive layer is a layer of thermally actuated polyethylene and ethylene vinyl acetate copolymer.
  • the stretchable laminate having a periphery that is larger than an outer periphery of the undergarment
  • FIG. 1 is a top plan view of an exemplary embodiment of a brassiere according to the present invention.
  • FIG. 2 is an exploded sectional view taken along line 2-2 of FIG. 1;
  • FIGS. 3-4 schematically illustrate a method according to the present invention of forming the brassiere of FIG. 1.
  • Brassiere 10 includes a pair of breast cups 12 that can be readily molded into a three dimensional cup shape, a central portion 14 extending between the breast cups; a bottom portion 16 that can lie flat against the chest wall of a wearer beneath the cups; and a pair of side panels 18 that extend from the breast cups 12 and provide a body circling arrangement.
  • brassiere 10 has a pair of shoulder straps 20 and a set interconnecting clasps 22.
  • Brassiere 10 can preferably have a pair of underwire channels 24 provided therein to receive a pair of underwires 26.
  • Each underwire 26 is preferably an arcuate, U-shaped member.
  • Each channel 24 is typically stitched to brassiere 10. However, each channel 24 may be glued or ultrasonically welded to brassiere 10.
  • Each channel 24 may be made from cotton, polyester or spandex.
  • Brassiere 10 can also include a central gore 28 to reinforce central portion 14 and provide additional separation between breast cups 12.
  • central gore 28 is made from a non-stretchable material, such as cotton, polyester or nylon. More preferably, central gore 28 is made from 100 percent cotton.
  • brassiere 10 includes a finished edge 30 defined about the periphery of the brassiere.
  • Finished edge 30 can be a straight edge, a scalloped edge, and any combination of the foregoing.
  • finished edge 30 has a decorative pattern such as the scalloped pattern illustrated in FIG. 1.
  • Brassiere 10 is, preferably, a fabric laminate of two or more layers as illustrated in FIG. 2.
  • brassiere 10 has a first layer 32 and a second layer 34 adhered to one another by an adhesive layer 36.
  • First and second layers 32, 34 each have a inner surface 38 and an outer surface 40.
  • adhesive layer 36 may be applied to cover inner surface 38 of first and second layers 32, 34 entirely or only over selected portions of the inner surfaces.
  • Adhesive free region 42 is illustrated in phantom in FIG. 3 and, thus, can form a non-bonded region (not shown) between first and second layers 32, 34.
  • adhesive free region 42 is defined at breast cups 12 so that first and second layers 32, 34 have the non-bonded region in the breast cups 12.
  • First layer 32 and second layer 34 are made from natural fibers or blend of natural and synthetic fibers.
  • first layer 32 and second layer 34 are made of a blend of cotton, polyester and spandex.
  • first layer 32 and second layer 34 are made of a blend having approximately 44% to 50% cotton, approximately 44% to 50% polyester and approximately 3% to 9% spandex. Even more preferably, first layer 32 and second layer 34 are made of a blend having 47% cotton, 47% polyester and 6% spandex.
  • Adhesive layer 36 is a thermoplastic adhesive.
  • adhesive layer 36 is a thermally actuated polyethylene and ethylene vinyl acetate copolymer. More preferably, adhesive layer 36 is a thermally actuated polyethylene and ethylene vinyl acetate copolymer that is sold under the trade name Delnet ® EP by Delstar Technologies, Inc. Delnet ® EP is made from high density polyethylene (HDPE) with an EVA skin layer on both sides to enable easier bonding.
  • HDPE high density polyethylene
  • Adhesive layer 36 has a base weight of approximately 0.45 oz/yd 2 ; a thickness of approximately 5.5 mils; a material direction (MD) boss count of approximately 24 per inch; a course direction (CD) boss count of approximately 25 per inch; a porosity of approximately 1000 cfm/ft 2 ; an MD tensile strength of approximately 2.4 lbs/in; a CD tensile strength of approximately 4.0 lbs/in; a skin soft point of approximately 110 degrees Celsius; and a processing range of greater than 123 degrees Celsius.
  • MD material direction
  • CD course direction
  • Delnet ® is the preferred adhesive for use in adhesive layer 36 as it does not "lock up" the cotton fibers in first layer 32 and second layer 34, thus allowing the first and second layers to maintain stretchability .
  • adhesive layer 36 including a net of adhesive strands of yarn (not shown) that cross over each other in a configuration that resembles a diamond shape allows brassiere 10 to maintain its stretch.
  • the diamond can be further identified with dots (not shown) interconnecting the strands. It is believed that when adhesive layer 36 is activated, the corners of the diamond or strands draws back to the crossover dots, which secure first layer 32 to second layer 34. It is also believed that this pulling back of the strands to the dots facilitates first and second layers 32, 34 maintaining their stretch.
  • Method 50 includes a first or cutting step 52, a second or assembly step 54, a third or activation step 56, and a fourth or trimming step 58.
  • first and second fabric layers 32, 34, as well as adhesive layer 36 are cut to a shape 60 that generally follows and approximates the outline of brassiere 10.
  • Shape 60 is slightly larger than finished edge 30 to be defined about the periphery of brassiere 10 so that a selvage or trim 62 remains in the shape for later removal during manufacture.
  • first layer 36 is positioned atop second layer 34, then first layer 32 is positioned atop adhesive layer 36 to form a sub-assembly 64.
  • Adhesive layer 36 is activated at third step 56 to cause sub-assembly 64 to form a laminate 66.
  • third step 56 can be heat treatment step in which adhesive layer 36 is thermally actuated causing first and second layers 32, 34 to adhere to one another and form laminate 66.
  • Trim 62 is removed from laminate 66 at fourth step 58 to provide finished edge 30 and, thus, to complete brassiere 10.
  • fourth step 58 can reciprocate a die and press into one another to die cut trim 62 from laminate 66.
  • brassiere 10 is fully glued around the perimeter of the garment
  • edge 30 can include the decorative pattern that enhances the aesthetic appeal of brassiere 10 as well allows the brassiere to better engage the body of the wearer.
  • shoulder straps 20 and interconnecting clasps 22 are attached to brassiere 10 after removal of trim 62.
  • method 50 can include a fifth or molding step 68.
  • laminate 66 can be introduced to a molding machine 70 for molding breast cup portions 12 into the laminate to give the cups a predetermined shape .
  • method 50 can include a sixth or underwire insertion step 72.
  • channels 24 and gore 28 are assembled into sub- assembly 64.
  • channels 24 are typically stitched to inner surface 40 of second layer 34, but alternatively may be glued or ultrasonically welded to the inner surface.
  • Central gore 28 is then positioned between channels 24.
  • laminate 66 presented to sixth step 72 includes channels 24 having open ends 74.
  • Sixth step 72 inserts each underwire 26 into each channel 24 through its open end 74.
  • Sixth step 72 then closes open ends 74 by stitching, gluing, or ultrasonic welding.
  • sixth step 72 is illustrated by way of example inserting underwires 26 after sub- assembly 64 is exposed to third step 56 to form laminate 66. However, it is contemplated by the present disclosure for sixth step 72 to be prior to third step 56 so that the third step not only forms laminate 66, but also closes open ends 74.
  • Brassieres constructed from fabric laminates made according to the present invention are highly resistant to unraveling due to the polyethylene and ethylene vinyl acetate copolymer used as an adhesive.
  • This adhesive permits the use of natural fibers, such as cotton, in manufacturing the brassiere as this particular adhesive does not "lock up" the cotton fibers and allows the material to maintain a degree of stretchability. Because of the construction of the fabric laminate, brassieres made from this fabric laminate do not require seams thus giving them an aesthetically pleasing seamless appearance. In addition, such brassieres are easier and less expensive to manufacture as construction involves a minimum of labor intensive assembly steps.
  • method 50 is illustrated by way of example as forming brassiere 10. Of course, it is contemplated by the present invention for method 50 to find equal use in the manufacture of other undergarments.
