Hochfeste feine spinngebundene Faser und hochfester feiner spinngebundener Stoff

摘要

A nonwoven fiber and fabric and process for production are provided which have comparable strength characteristics to conventional fibers and fabrics and are of a finer diameter. This is accomplished through a process of producing a nonwoven fabric made from at least one polymer which has a melt temperature between about 410 DEG and 470 DEG F. (210 DEG and 243 DEG C.), xylene solubles between about 3.5 and 7.0%, a melt flow rate between about 30 and 45, and an isotacticity of at least about 94%, extruding the polymer through fine openings, drawing the polymer to produce fibers of a denier of 1.4 or less, and then depositing the fiberized polymer on a collecting surface to form a web of disbursed fibers. The nonwoven fabric of this invention may be used in products such as, for example, diapers, feminine hygiene products, adult incontinence products, wound dressings, bandages, sterilization wraps, surgical drapes and wipers.
