The invention relates generally to a brassiere, also commonly called a bra as well as other garments providing the same functions.
Bras are commonly worn by women to provide support for their breasts and for enhanced shape and appearance. Other garments have built-in bras and can provide the same function. Bras are often constructed to provide different amounts of support. Often, conventional bra constructions require a choice to be made by a wearer of the bra between support and comfort. For example, some women find certain bras to be too restrictive. Sometimes, they find the fabric to be uncomfortable. Some Bras are made with an underwire design. Some women find the underwire to be uncomfortable. Some bras have a tendency to “ride-up” and are tugged-on repeatedly during the day.
Other types of bras, such as bras with a sports bra type of construction, reduce natural movement of the breasts more than might be desirable for certain situations. Other bras that supply relatively high support can lead to an unnatural, restricted appearance and often impose their own shape on the natural shape of the breast or flattened the breasts against a woman's chest. Other bras, especially those with shaping pads, can feel clammy.
Accordingly, it is an object of the invention to provide a bra that overcomes drawbacks, inadequacies and limitations of the prior art.
Generally speaking, in accordance with the invention, a lightweight, but supportive garment constructed to support the breasts of a user wearing the garment, such as a bra, tank top, shirt, leotard, sports bra or other garment is provided to overcome deficiencies of the prior art. The bra can be formed with a front half and a rear half, having a top and a bottom. One or two shoulder straps can extend from the top of the front half to the top of the rear half.
The garment can be formed from a front half and a rear half. The top ends of respective shoulder strap halves of the front panel can be attached to respective top ends of shoulder strap halves of the rear panel, at two shoulder strap seams, to form two shoulder straps. The side edges of the front panel can be attached to respective side edges of the rear panel, at side seams, to form a body section. The two shoulder straps connected to the body section define two arm holes at the area above the side seams. The shoulder straps and the top edges of the front and rear panels define front and rear necklines.
An inner front panel of fabric can be attached as a second fabric layer to overlap an inner surface of the front panel to form a bust section of the bra. For example, the inner front panel can overlap the shoulder strap halves of the front panel and extend down towards, but not all the way to the bottom edge. The inner front panel can be positioned across the front panel, extending toward, but not reaching the side seams. The inner front panel is positioned to overlap and contain the breasts of a wearer of the bra.
The bra should be formed from free cut knit fabric. Preferred fabrics have a high level of spandex. The bra includes strategically positioned bonded film strips of elastomeric adhesive between two layers of fabric to provide supportive resilient function. The adhesive is preferably urethane based adhesive, especially ester modified urethane adhesive. For example, a curved bonded film of adhesive can be provided between the front panel and the inner front panel (second layer), at a position to be at the bottom of the bust section of the bra, at a location that would be under a wearer's breasts. A center front strip can be provided between the front panel and the inner front panel to separate the bust section into left and right cups or pad holding pockets. A bottom band can be provided by folding the bottom edge of the front and rear panels into a hem and disposing adhesive in the fold to create a resilient band entirely around the bottom edge of the bra. Adhesive can also be used to bond the fabric layers of the front panel and rear panel at the side seams. An adhesive band can also be formed at the front neckline at the top edges of the front panel and inner front panel and at the arm holes where the inner front panel overlaps the front panel.
In an embodiment of the invention, a slit for receiving cup pads between the front panel and inner front panel can be provided, preferably through the inner front panel. The cup pads can be formed from foam material, for enhanced shaping and coverage properties. The pads are preferably perforated for moisture control. It is advantageous to cover the pads with non-absorbent fabric, such as polyester knit.
Preferred adhesives for forming the bonded film strips discussed above, between two layers of fabric, whether folded or overlapping, include ester modified polyurethane adhesives. The adhesive strips generally have a thickness of about 20-30, preferably about 23-28, more preferably about 25 μm (0.001 inches). The density of the adhesive strips should be about 30-40, preferably about 25-35, more preferably about 31 g/m2. The width of the adhesive strips is generally about 0.5 to 2.5 cm. The bands should be elastic, lay flat when the bra is worn and be minimally visible.
A strip of adhesive can be placed between the front panel and inner front panel to define the lower extent of the bust section of the front of the bra. This under-bust strip is preferably flat, about 1-2 cm, preferably about 1.25-1.75 cm wide, more preferably about 1.3-1.6 cm wide most preferably about 1.4 cm wide. This strip provides flexible, expandable support of the breasts and is generally considered more comfortable than an under wire.
A central strip can separate the bust section into individual left and right cups or pad pockets. This central strip is preferably flat and about 1-2 cm, more preferably about 1.25-1.75 cm wide, most preferably about 1.4 cm wide.
The fabric for a bra in accordance with the invention is preferably free cut knit material. Free cut knits do not unravel at unfinished edges thereof. Free cut fabric eliminates the need for bulky finishing at the edges. Such finishing can interfere with comfort and can show through clothing and make the bra more visible. The fabric is advantageously a combination of nylon or polyester with spandex. The nylon is preferably 20D nylon yarn and the spandex is preferably 30D spandex. The fabric should be formed with at least about 15%, preferably at least 25% and most preferably at least 30% spandex. A 40 gauge knitting machine is preferred. The fabric should have a density between about 100 and 200 g/m2, preferably about 145 to 165 g/m2, most preferably about 155 g/m2.
The fabric is preferably subjected to a moisture management treatment. The fabric should be treated after dyeing and finishing. Preferred treatment involves a bath of hydrophilic silicone, preferably hydrophilic silicone oil type 919. Preferred silicone treatments comprise modified amino silicone oils with small percentages of penetrating agent (e.g., ternary polymerization). Hydrophilic amino modified silicone should be selected that give the fabric a feather-like softness feel and smoothness with improved moisture wicking capabilities. PH values for preferred silicone treatment material ranges from 5.5-6.5. Preferably, it does not contain Nonylphenol & Octylphenol Polyoxyethylene.
Accordingly, it is an object of the invention to provide a bra and an improved method of making a bra.
Still other objects of the invention will in part be obvious and will, in part be apparent from the specification and drawings. The invention accordingly comprises the article of manufacture and the method of making the article which will be exemplified in the articles and methods hereinafter described, and the scope of the invention will be indicating the claims.

As used herein, identical reference numerals will indicate similar structures. The drawings, which are not necessarily drawn to scale, are for purposes of illustration only and are not intended to be interpreted as limiting the scope of the invention.
A garment constructed to support the breasts of a user wearing the garment in accordance with a preferred embodiment of the invention is shown generally in
Front panel 110 comprises an outer front surface 111 and an inner front surface 112. Rear panel 120 comprises an outer rear surface 121 and an inner rear surface 122. An overlapped side seam 117 is present where front panel 110 meets rear panel 120. It is preferred for front panel 110 to be over rear panel 120 at side seam 117.
A side seam bonded film 118 is located between inner front surface 112 and outer rear surface 121 where front panel 110 overlaps rear panel 120. As used herein, the layer of adhesive between two layers of fabric will be shown as a stippled strip. Those of ordinary skill will appreciate that the strip is a bonded film and not a layer on an outside surface. However, it will be depicted in this manner so that the location of the strips of adhesive will be apparent, even though they are covered.
Side seam bonded film 118 is a 1.3 cm wide flat strip of elastomeric adhesive between two layers of fabric. In alternative embodiments of the invention, side seam bonded film 118 can be about 1.0 to 1.5 cm wide, more preferably 1.2 to 1.4 cm wide. Other dimensions are acceptable.
A pair of front shoulder strap portions 1110 extend from the top of front panel 110. A pair of rear shoulder strap portions 1120 extend from the top of rear panel 120. Front shoulder strap portions 1110 are joined to rear shoulder strap portions 1120 at a shoulder strap seam 135. Shoulder strap seam 135 is an overlap seam, but other constructions are possible. A strip of shoulder seam adhesive (bonded film) 136 is present between the edges of front shoulder strap portion 1110 and rear shoulder strap portion 1120 at each shoulder strap seam 135. Front shoulder strap portion 1110 preferably lays over rear shoulder strap portion 1120 at the rear side of bra 100.
Shoulder seam adhesive strip 136 is a 1.2 cm wide bonded film. The film is approximately 25 μm (0.001 inches) thick and has a density of about 31 g/m2. In alternative embodiments of the invention, the strip of shoulder seam adhesive can be about 1-1.5 cm wide, preferably 1.1-1.3 cm wide; and about 20 to 30 μm thick. Other dimensions are acceptable.
Referring to
Bra 100 includes a body section 150 located below shoulder straps 130. Bra 100 also includes a back section 170 located below shoulder straps 130 on rear panel 120. An inner edge 139 of front shoulder strap portion 1110 and a top edge 159 of body section 150 define a front neckline 140. An outer edge 134 of shoulder straps 130 define a pair of arm holes 137.
An armhole film 138, formed as a strip of elastomeric adhesive, is present between front panel 110 and second layer 310, along outer edge 134 of front panel 110, defining part of armhole 137, where an edge of inner front surface 112 meets an edge of second layer 310. A neckline film 148, formed as a strip of elastomeric adhesive, is present between the fabric of front panel 110 and second layer 310 along top edge 159. Armhole film 138 and neckline film 148 are 1.4 cm wide bonded films and can be similar in construction to shoulder seam film 115. In alternative embodiments of the invention, the armhole film and/or the neckline film can be about 1 to 2 cm wide, preferably 1.25-1.75 cm wide, more preferably about 1.3 to 1.5 cm wide. These films should be approximately 20-30 μm preferably about 25 μm thick and have a density of about 25-35, preferably 31 g/m2. Other dimensions are acceptable.
Referring to
Under bust film 475 performs a similar supportive function as an underwire. However, because it is flat, thin and elastic, under bust film 475 can feel more comfortable than a conventional underwire. The fabric of bust portion 450 between under bust film 475 and neckline 140 should be contoured, for proper shaping and support, to match the shape of a wearer's breasts.
Bra 100 also includes a center front bonded film 480, bonding inner front surface 112 to second layer 310 and forming a pair of pad holder pockets 452 and 453 therebetween, accessible by a pair of respective slits 190. Center front bonded film 480 extends from neckline 140 to under bust film 475. Center front film 480 bisects bust portion 450 into a left pad holder pocket 452 and a right pad holder pocket 453. Center front bonded film 480 is about 1.5 cm wide. In alternative embodiments of the invention, it can be from 1 to 2 cm wide, preferably 1.25 to 1.75 cm wide, more preferably 1.4 to 1.6 centimeters wide.
The bottom edge of bra 100 includes a bottom band 180. The bottom of bra 100 is folded over to form a two-layer structure hem. A bonded film of elastic adhesive is disposed in the space between the two layers. Bottom band 180 extends completely around the bottom edge of bra 100. Bottom band 180 provides additional structure and support to bra 100. In addition, bottom band 180 helps prevent bra 100 from riding up a wearer. Bottom band 180 also provides a more structured gripping portion to help adjust the placement of bra 100 on a wearer.
Bottom band 180 can be formed as a bonded flat film of elastomeric adhesive between the two plies of fabric. The inside of bottom band 180 can be textured or otherwise modified to prevent bra 100 from riding up. The bonded film forming bottom band 180 can comprise the same elastomeric adhesive having the same density and thickness, as discussed above. The film should be approximately about 20-30 μm preferably about 25 μm thick and have a density of about 25-35, preferably about 31 g/m2. Bottom band 180 comprises an about 2 cm wide bonded film. In alternative embodiments of the invention, the bonded film can be about 1 to 2.5 cm wide, preferably 2.25 to 1.75 cm wide, more preferably about 1.9 to 2.1 centimeters wide.
As shown more clearly in
Foam pads 300 are molded for both shaping, coverage and support as desired. The inner and outer surfaces of foam pads 300 are preferably laminated with moisture-proof fabric, such as 100% polyester fabric. In addition, the pads can be perforated, preferably every 0.25 inches from each other. These perforations help permit body moisture to evaporate through the pads.
The fabric for bra 100 is preferably a synthetic free cut fabric with a high spandex content. It can be formed from natural fibers or preferably various fabric polymers, such as polyester, nylon and different polymer blends. Preferably, the fabric is a nylon/spandex (elastane) blend. Advantageous fabrics comprise at least about 15% spandex, preferably at least 25% spandex and most preferably at least 30% spandex. The fabric should be knit in a free cut fashion, which does not unravel at unfinished ends thereof. A 40 gauge knitting machine is preferred. The material should have a density between about 100 and 200 g/m2, preferably about 145 to 165 g/m2, most preferably about 155 g/m2.
The fabric for constructing bra 100 is preferably subjected to a moisture management treatment to increase the hydrophilic properties of the material and enhance its moisture wicking properties. The fabric should be treated after dyeing and finishing. Preferred treatment involves a bath of hydrophilic silicone, preferably Hydrophilic Silicone Oil type 919. For example, Cosmethicone® SF-919 Silicone Surfactant, a PEG/PPG-15/10 dimethicone can be used. Preferred silicone treatments comprise modified amino silicone oils with small percentages of penetrating agent (e.g., ternary polymerization). Hydrophilic amino modified silicone helps give the fiber an enhanced feather-like softness feel and smoothness with improved moisture wicking capabilities. PH values for preferred silicone treatment material ranges from 5.5-6.5. Preferably, it does not contain Nonylphenol & Octylphenol Polyoxyethylene.
The adhesive for forming the bonded film strips of bra 100 should remain elastic even after curing. Clear adhesives are preferred. One preferred adhesive is an ester modified one component polyurethane adhesive. It can be applied with a flat press machine. The resulting strip of polyurethane can bond two layers of fabric together and forms a fabric-backed elastic strip. Varying the width and thickness of the adhesive strip can provide variations in flexibility, structure, support and feel for the final garment product.
