US Patent 8038505 Brassiere cup and pad structure

A brassiere cup and pad structure is revealed. The brassiere cup and pad structure consists of two outer linings made from polypropylene and an inner padding made from the same material-polypropylene. By the polypropylene with low melting point, the dye degradation on the outer lining caused by high temperature during foaming processes can be avoided. Thus the amount of defective products in which the outer lining have spots resulted from degraded dyes is reduced. Moreover, the shortcoming of general inner padding made from foam that is easy to turn yellow over time is improved effectively.
