As shown in fig. 1 to 5, the present invention provides a steel ring-free composite bra comprising a front panel 1, a rear panel 2 and a cup pad (not shown).
The front sheet 1 includes an inner layer 11, an intermediate layer 12, and a surface layer 13 arranged in this order. The inner layer 11 is a skin layer.
The inner layer 11 is provided with an inner cup pad area 111, an inner adhesive area 112 and an inner blank area 113. The inner cup pad region 111 corresponds to a cup pad.
The inner adhesive area 112 covers the shoulder strap edge of the inner layer 11, the lower edge of the inner coaster area 111, the side-to-side edge, the bottom peripheral edge, and the heart area. The arrangement of the inner adhesive area 112 to cover the shoulder strap edge of the inner layer 11, the lower edge, the side ratio edge and the bottom peripheral edge of the inner cup pad area 111 can effectively avoid the uncomfortable wearing problem caused by excessive adhesive on the close side of the bra. The inner adhesive region 112 is a glue application region, and the inner layer 11 can be bonded to the intermediate layer 12 by the inner adhesive region 112. The glue on the inner adhesive area 112 may be applied by dispensing, brushing and film forming.
The inner blank 113 covers the middle area and the junction area of the shoulder strap of the inner layer 11 with the side ratio and the bottom, and the inner adhesive 112 is disposed around the inner cup pad 111 and the inner blank 113. The arrangement of the inner blank area 113 can effectively improve wearing comfort, particularly the problem of shoulder pressing can be avoided when the inner blank area 113 covers the middle area of the shoulder strap, and the problem of uncomfortable wearing caused by excessive adhesive on the close side of the bra can be effectively avoided when the cover side of the inner blank area 113 is arranged in comparison with the connecting area of the cover side and the bottom.
The middle layer 12 is provided with a middle cup pad area 121, a middle bonding area 122, a first hollowed-out area 123, a second hollowed-out area 124, a hollow white area 125 and a connecting strip 126. The middle cup pad region 121 corresponds to a cup pad. The middle adhesive area 122 covers the shoulder straps, side ratios, and bottom perimeter of the middle layer 12. The middle bonding region 122 is a rubberized region and the intermediate layer 12 may be bonded to the skin layer 13 by the middle bonding region 122. The glue on the middle adhesive area 122 may be applied by means of dispensing, brushing and film.
The first hollowed-out area 123 is located at the front collar of the middle layer 12, and the second hollowed-out area 124 is located in the heart-shaped area of the middle layer 12. The first hollowed-out area 123 corresponds to the second hollowed-out area 124.

In one embodiment of the steel ring-free composite bra of the present invention, the first hollowed-out region 123 has an inverted trapezoidal shape and the second hollowed-out region 124 has a heart shape.
The inverted trapezoid shape of the first hollowed-out area 123 can improve the wearing comfort of the bra and reduce the feeling of chest compression. The heart shape of the second hollowed-out area 124 can achieve the effects of better edge curling prevention and breast lifting.
In one embodiment of the steel ring-free composite bra of the present invention, the inner layer 11, the middle layer 12 and the rear inner layer 21 are cross-plied, and the top layer 13 and the rear top layer 22 are vertical plied. The different yarn orientations of the layers of the front and back panels 1, 2 are advantageous in avoiding the problem of non-uniform stress of the chassis and/or shoulder straps caused by a single yarn orientation.
The inner layer 11 and the middle layer 12 can adopt transverse yarns to be made into the fabric, the surface layer 13 can adopt vertical yarns to be made into the fabric, the vertical yarns are good in shape retention, and the transverse yarns of the inner layer 11 and the middle layer 12 can laterally retract the chest to be made into the fabric, so that the chest is more attractive. The back lining layer 21 can adopt a transverse yarn-oriented fabric, the back surface layer 22 can adopt a vertical yarn-oriented fabric, the vertical yarn-oriented fabric has good shape retention, and the transverse yarn-oriented of the back lining layer 21 can improve wearing comfort.
In one embodiment of the underwire-free composite bra of the present invention, the posterior bonding region 211 includes a posterior shoulder strap bonding region 2111, a posterior specific bonding region 2112, and a posterior bottom perimeter bonding region 2113. The rear inner shoulder strap bonding area 2111 has a smaller footprint pitch than the rear ratio bonding area 2112 and the rear inner bottom perimeter bonding area 2113. The smaller gap between the adhesive marks of the back shoulder strap adhesive area 2111 can balance the strength of the shoulder strap and the bottom, and effectively avoid the phenomenon of flying ratio. In addition, the full glue setting of the back shoulder strap bonding area 2111 can enable the back collar dynamics to be greater than the back armpit, effectively avoids the armhole atress to be big to cause the phenomenon of falling the shoulder strap.
In one embodiment of the steel ring-free composite bra of the present invention, a fourth hollowed-out area 114 is provided on the side edge of the inner layer 11, a fifth hollowed-out area 127 is provided on the side edge of the middle layer 12, and the fourth hollowed-out area 114 and the fifth hollowed-out area 127 are staggered. Because the back sheet 2 is connected with the front sheet 1 at the side ratio edge of the front sheet 1, the arrangement of the fourth hollow area 114 and the fifth hollow area 127 can avoid the problem of uneven thickness caused by excessive fabric layers.
In particular, the fourth hollow region 114 and the fifth hollow region 127 may each have a rectangular shape, and edges of the fourth hollow region 114 and the fifth hollow region 127 are connected.
