PROCESSING CORE AND SUIT SEWED WITH THE SAME PROCESSING CORE

PURPOSE:To provide a processing core capable of supplying readily a front side of a front body of an upper garment or a lower neck part with roundness approximately in the lateral direction without using high-quality sewing technology requiring skill. CONSTITUTION:A processing core 1 to be used as a core of an upper garment is obtained by fixing a thermally shrinkable padding cloth 5 obtained by wearing thermally shrinkable synthetic yarn as either warp or weft to a part corresponding to a front side of a front body of an upper garment, at the back of its base core 2, reaching from a swollen part A of a breast to a front cut part C, in such a way that the thermally shrinkable synthetic yarn is positioned approximately in the lateral direction. A thermally shrinkable padding cloth 6 obtained by weaving thermally shrinkable synthetic yarn as either warp or weft is fixed to a part corresponding to a lower neck part of the upper garment, at the surface side of the base core 2, in such a way that the thermally shrinkable synthetic yarn is positioned approximately in the lateral direction.
