摘要： A waved meltblown fiber web of the present invention relates to a fiber web prepared by a meltblown method and is characterized by a preparation method in which a meltblown microfiber comes in contact with collection portions having different surface velocities so as to be collected. The waved meltblown fiber web of the present invention is characterized in that: a part of meltblown microfibers reaches a low velocity collection portion so as to be horizontally layered, thereby forming a horizontal fiber layer (10); another part of the meltblown microfibers reaches a high velocity collection portion of which the surface velocity is greater that of the low velocity collection portion so as to form a serpentine vertical fiber layer (20); and the upper end of the vertical fiber layer (20) becomes entangled so as to form a wave shaped wave layer (30) forming the uppermost portion of the fiber web.

摘要： A method for forming a biodegradable polylactic acid suitable for use in fibers is provided. In one embodiment, for example, a polylactic acid is melt blended with an alcohol to initiate an alcoholysis reaction that results in a polylactic acid having one or more hydroxyalkyl or alkyl terminal groups. By selectively controlling the alcoholysis conditions (e.g., alcohol and polymer concentrations, catalysts, temperature, etc.), a modified polylactic acid may be achieved that has a molecular weight lower than the starting polylactic acid. Such lower molecular weight polymers also have the combination of a higher melt flow index and lower apparent viscosity, which is useful in a wide variety of fiber forming applications, such as in the meltblowing of nonwoven webs.
