Seamless lace lingerie article

Abstract

The present invention concerns a lace article for maintaining and supporting part of a woman's body. The lace article is an elastic material capable of being simultaneously thermoformed, welded and heat bonded to at least a reinforcement element. The elastic material is capable of being subjected without damage to the yarn to a permanent deformation by thermoforming during a molding process for producing lingerie in all standardized sizes and preserving after deformation a mechanical strength and elasticity such that the articles preserve their capacity to support and maintain the part of the body on which they are worn.
