Elastic and/or decorative trim is attached along an edge of a fabric body of a garment without sewing. The trim comprises a textile material containing fibers of thermoplastic material. The fabric edge to which the trim is attached can be any type of fabric, not necessarily containing any thermoplastic fibers. The trim is attached by wrapping the trim around the fabric edge so that the edge is sandwiched between two opposing portions of the trim, and then localized regions of the trim are heated, preferably ultrasonically, to cause the thermoplastic material in the trim to become plastic and flow together from the opposing portions, thus penetrating through the fabric edge. The thermoplastic material is then allowed to cool and solidify, thereby attaching the trim to the fabric edge. Also disclosed are garments having ultrasonically formed joints between two or more fabric panels. Particular joints are described enabling non-ultrasonically bondable panels to be ultrasonically joined to other ultrasonically bondable panels. |
