SHOE-REINFORCEMENT MATERIAL AND BARRIER UNIT, COMPOSITE SHOE SOLE, AND FOOTWEAR CONSTITUTED THEREOF

摘要

The invention relates to a shoe reinforcing material (33) comprising a fiber composite (1) with a first fiber component (2) and a second fiber component (3), comprising two fiber portions (4, 5). The first fiber component (2) has a first melting temperature and a first softening temperature range inferior thereto, and a first fiber portion (5) of the second fiber component (3) has a second melting temperature and a second softening temperature range inferior thereto. The first melting temperature and the first softening temperature range are higher than the second melting temperature and the second softening temperature range. The second fiber portion (4) of the second fiber component (3) has a higher melting temperature and a higher softening temperature inferior thereto than the first fiber portion (5). The fiber composite (1), as a result of the thermal activation of the first fiber portion (5) of the second fiber component (3), is thermally solidified at an adhesive softening temperature lying in the range of the second softening temperature while maintaining the thermally solidified area permeable to steam.
