Technical Field

The invention belongs to the field of sports bra design, and particularly relates to a functional bra comfortable to exercise and a personalized manufacturing method thereof.

Background

The sports corsage is developed on the basis of the bra, and basically inherits the structure and the characteristics of the bra; with the development of science and technology, the increasing maturity of human-computer efficiency and the wide spread of world competitive sports, the sports corsage is very important for female athletes and sports enthusiasts. The sports corsage is not only beautiful but also has to have certain functions to protect the female breasts. In sports, the problem of embarrassment of female athletes is that the clothes rub the nipples to cause injury to the nipples. To solve these problems, researchers and manufacturers in various countries around the world have been developing sports corsets in succession.

At present, most of sports bras adopt a closed structure adhered to skin, the brassiere is poor in ventilation effect, and can cause serious chest sweating in the process of sports, influence heat dissipation and generate discomfort; and its elasticity state of this application is comparatively fixed, and certain power can be exerted to inevitable under the motion state on the nipple, arouses uncomfortable feeling easily.

Disclosure of Invention

Aiming at the defects of the existing bra, the bra cups are connected with the telescopic belts, the elastic belts give certain elastic force to the cups, and the cups can generate certain elastic change along with the motion state in motion, so that the change relieves and lightens the force applied to nipples, and the comfort of the breasts during the motion is improved.
