Abstract: The invention discloses a sheath for bra wire ring. It includes a hollow sheath body made of cloth, and there is a hollow part for holding the wire ring to be inserted in the hollow sheath body; it also comprises a core wire inserted in the hollow part, and the core wire slides relative to the hollow sheath body. Such design solves the problem of resistance when the wire rings are inserted into a flat bra wire ring sheath, resulting in that in the process of manufacturing bra, the phenomena of wrinkles and holes left on the surface of the sheath and the tightness of the sheath caused by inserting wire rings can be obviously improved, and making the product more beautiful and simultaneously enhancing the comfort of wearing the bra for females.

Abstract: A velvet sheath for bra wire rings and a bra using the velvet sheath, the sheath comprises a main body holding a hollow part and formed by an upper fabric and a lower fabric, both sides of the hollow part of main body interweave and connect the upper fabric and the lower fabric to form velvet woven grid surfaces by velvet warp threads crossed up and down, respectively, and the sheath is sewn under the bra cup. The velvet sheath for bra wire rings according to the present invention will not appear rough surface and uneven elasticity caused by wire rings pulling the sheath after wire rings inserted into the curvedly sewn sheath or when users wear such bras later, and may ameliorate deformation, wrinkles and tightness of the sheath caused by the uneven tension formed by bending of wire rings and can cushion the compression induced by bending of wire rings without affecting the effect of the sheath on fixing the wire rings.
