Description

TECHNICAL FIELD

The present disclosure relates generally to wearing apparel and, more specifically, to an undergarment, in particular to a functional bra that is suited for the unique needs of a woman whose body temperature increases as she progresses through pregnancy and afterwards when she may be nursing a child. The present disclosure also relates to a method for manufacturing same.

BACKGROUND

A bra is an article of clothing that covers and supports a woman's breasts.
Common bras have two cups to cover and hold the breasts, shoulder straps connected to each of the cups, and a band encircling the torso under the breasts.
Nursing and maternity bras as one type of functional bras were created to permit a woman to breastfeed a baby without having to remove her bra entirely. This is accomplished either through a specialized opening in a bra cup to expose part of the breast, or through bras with cups that have clasps above them that can be detached to pull down one or more cups of the bra to expose the breast underneath.
Such nursing and maternity bras are often made of yarn, preferably cotton, with the same knitted fabric that absorbs leaking milk and sweat produced. However, during pregnancy, when the woman's breasts become heavier and at the same time the body temperature increases, the yarn alone is not enough to meet the needs in terms of support and breathability
WO 2018 204 681 A1 discloses a bra with multilayer pad to absorb fluids and increase breathability. JP 312 9647 U discloses a bra with a cooler insertion part for receiving frozen coolers. US 2016 021 940 A1 discloses a bra with zones of different knit structure for optimizing breast support.

PROBLEM TO BE SOLVED

In view of the above, there is a need to provide a functional bra, in particular a nursing and/or maternity bra that ensures breathability without compromising support.

SUMMARY

According to a first aspect of the present invention, there is provided a functional bra, in particular a maternity and/or nursing bra. The bra comprises a front section shaped to cover at least a portion of a chest area of a wearer, including a pair of cup portions shaped to accommodate respective ones of breasts of the wearer, and a back section shaped to cover at least a portion of a back of the wearer. At least one of the cup portions and the back section is formed from knit fabric with different knit structures representing zones of different breathability such as at least a cool zone and a support zone. The cool zone is adapted to cover a sweat-sensitive area on skin of a wearer, and has a different knit structure than the support zone with a higher breathability.
The knit fabric, preferably the functional bra, may be fabricated from a single yarn composed of a stretchablematerial, preferably from a cotton-free material, in particular from a material blend of polyester and elastane or polyamide and elastane, in particular nylon and spandex. This may result in a single piece of knit fabric without any seam, sewing or stitching between the cool zone and the support zone in spite of the different knit structures.
The knit fabric may be composed of a blend including 80 to 98%, more preferably in between 85 to 97%, in particular 86 to 95% polyamide/nylon and an inversely corresponding percentage of elastane/spandex. The selected yarn may absorb humidity, i.e. sweat, and may convey it from the skin to the environment outside the bra.
The functional bra may further comprise a midriff portion, in particular a seamless rib knit band, which may underline the cup portions. The seamless rib knit band may be adapted to extend at least partially around a portion of a torso under the breast of the wearer. The seamless rib knit band may be formed from knit fabric composed of a blend including 70 to 95%, more preferably in between 75 to 92%, in particular 80 to 90% polyamide/nylon and an inversely corresponding percentage of elastane/spandex.
The knit structure of the cool zone may have a wider or coarser mesh than the support zone. This may lead to larger meshes for air passage in the cool zone and a better support, in particular relatively lower elasticity, of the support zone.
The volumetric mass density of the knit fabric in the cool zone may be about 1,5 to 20, preferably 2 to 15, in particular 5 to 10 times lower than in the support zone.
The different knit structures of the cool and support zone may differ in their mesh size so that they can be seen with the naked eye.
The knit structure of the cool zone may be at least one of a jacquard knit and an open knit mesh. The knit structure of the support zone may be a jersey knit.
The cool zone may be at least partially or completely enclosed by the support zone.
The cool zone may be adapted to cover at least a portion of a thoracic spine area, in particular a floating rib area, and an upper or lower edge area of the breast.
The cool zone may be provided on the cup portions and may extend partially along a pair of neckline portions of respective ones of the cup portions. The neckline portions preferably continuously transition into each other, preferably by way of a U or V shape, and partially along a pair of lower edge portions of respective ones of the cup portions. The cool zone on a respective one of the pair of neck portions may have a strip shape with a constant wideness. The upper and lower edges of the cool zone may be parallel. The cool zone may widen towards the neckline.
The cool zone may be provided on the back section and may extend at least partially along a thoracic spine portion of the back section, preferably between the upper edge and the lower edge of the back section with an hourglass and/or trapezoidal shape or a shape that may correspond to an inverted T. Edges of the T between a longitudinal portion of the T and transversal portion of the T may be smoothed. Alternatively, the cool zone may have the shape of a U.
The functional bra may be composed of the knit fabric as a single layer.
Alternatively, the functional bra may comprise a double layer of knit fabric disposed to overlap the front section, in particular the pair of cup portions. The layers may be composed of the same material and knit structure. The layers may define a cavity, in particular an opening or closable pocket, for receiving a foam cup. The use of two layers at the breast nipple zone may allow for improved support, hiding of nipple, and breast modeling as an esthetic function.
The functional bra may further comprise a foam cup, preferably a pitted or riddled foam cup, between the layers. The foam cup may be provided with ventilation elements for enhanced breathability, in particular holes. The holes in the foam cup allow the passage of air, may improve breathability and cooling.
The cool zone(s) at the cup portions may at least partially cover the foam cup or at least a perforated portion of the foam cup. Alternatively, said cool zone(s) may be arranged below or above the foam cup, preferably so that the foam cup is adjacent to the cool zone.
The functional bra may further comprise a pair of shoulder portions extending between respective ones of cup portions and the back section. The shoulder portions may be adapted to extend over respective ones of shoulders of the wearer.
The functional bra may further comprise a midriff portion, preferably composed of a rib knit, in particular a 2x1 rib knit. The midriff portion may underline the cup portions and may be adapted to extend at least partially around a portion of a torso under the breast of the wearer.
The functional bra may further comprise an opposed pair of side sections extending between the front section and the back section. The side sections may be shaped to cover at least a portion of respective ones of sides under arms of the wearer.
According to a second aspect of the present invention, there is provided a method for manufacturing a functional bra, in particular a maternity and/or nursing bra. The method comprises a first step of providing a single yarn composed of a stretchable and breathable material, preferably a cotton-free material, in particular a material blend/composition of polyester and elastane or polyamide and elastane, in particular nylon and spandex. The method further comprises a second step of forming the single yarn to a knit fabric with different knit structures representing zones of different breathability such as a cool zone and a support zone, and a third step of forming at least one of cup portions, shaped to accommodate respective ones of breasts of the wearer, and a back section, shaped to cover at least a portion of a back of the wearer, of the bra from said knit fabric. The cool zone is adapted to cover a sweat-sensitive area on skin of a wearer, and has a different knit structure than the support zone with a higher breathability.
