A heating cloth that easily and securely fits to the flexable parts, such as elbows and knees, and further follows and is applicable with high morphological changeability to the curved parts, such as shoulders and arms, neck and foots, etc. and other various parts of the human body; and a process for producing the same. There is provided a heating cloth comprising an exothermic composition molding accommodated in an accommodation bag, characterized in that the accommodation bag is composed of a base material and a covering material; and that the covering material covers the exothermic composition molding superimposed on the base material; and that the exothermic composition molding at its periphery is heat sealed so as to create protrudent and depressed pars; and that protrudent-part segmented heating parts having the exothermic composition molding accommodated therein are arranged via depressed-part segmenting parts of heat seal portion; and that an assembly of segmented heating parts form a heating part; and that the volume of exothermic composition molding is in the range of 0.1 to 30 cm3, the ratio between the volume of exothermic composition molding and the volume of segmented heating parts in the range of 0.6 to 1.0, the maximum height of segmented heating parts in the range of 0.1 to 10 mm, and the width of segmenting parts being the spacing of segmented heating parts in the range of 0.3 to 50 mm; and that at least in a plane orthogonal to the thickness of heating cloth, the minimum bending resistance is <= 100 mm.
Cette invention a pour objet un tissu chauffant recouvrant facilement et fermement les membres flexibles, comme les coudes et les genoux, dont l~applicabilité évolue avec le potentiel de changement morphologique important des membres courbes, tels que les épaules et les bras, le cou et les pieds, etc., et de plusieurs autres parties du corps humain ; ainsi qu~un processus de production. Ce tissu chauffant comprend une composition exothermique à mouler stockée dans une housse de rangement, caractérisée en ce que la housse de rangement est composée d~un matériau de base et d~un matériau d~enrobage ; et en ce que ce matériau d~enrobage recouvre la composition exothermique à mouler superposée sur le matériau de base ; et en ce que la composition exothermique à mouler est, à sa périphérie, jointe thermiquement de manière à former des parties saillantes et déportées; et en ce que les parties chauffantes segmentées saillantes, dotées d~une composition exothermique à mouler et stockée, sont disposées par le biais de zones de segmentations à parties déportées de la zone du joint thermique ; et en ce qu~un assemblage des parties chauffantes segmentées forme un élément chauffant ; et en ce que le volume de la composition exothermique à mouler est compris entre 0,1 et 30 cm3, le rapport entre le volume de la composition exothermique à mouler et le volume des parties chauffantes segmentées se trouve entre 0,6 et 1, 0, la hauteur maximale des parties chauffantes segmentées est comprise entre 0,1 et 10 mm, et la largeur des parties segmentées, constituant l~espacement existant entre les parties chauffantes segmentées, se trouve entre 0,3 et 50 mm; et en ce que, au minimum sur un plan orthogonal par rapport à l~épaisseur du tissu chauffant, la résistance à la pression minimale est <= à 100 mm.
