Fibrous padding material with good compression resistance ability and air permeability, which is poly (1,4 - cyclohexane - - represent dimethylene terephthalate) - hollow fibers contains

摘要

The present invention relates to a fibrous cushioning material, which of poly (1,4 - cyclohexane - - represent dimethylene terephthalate) - hollow fibers (pct - hollow fibers) is formed and inherent properties, such as heat resistance, chemical stability, elasticity and bulkiness, wherein, due to a hollow configuration of the fibers, also a light weight, is possible. The present invention is further brings in to a fibrous padding material with 80 degree. -% to 60 degree. -% pct - hollow fibers having a melting temperature of 280°C. to 290°C. and with 40 degree. -% to 20 degree. -% bonding fiber with a lower melting point than the pct - hollow fibers, in order to the pct - hollow fibers are joined to each other, wherein the fibrous padding material an optimized compression resistance ability and air permeability and, consequently, conventional polyurethane - based padding materials is able to replace.
