摘要： The present invention provides a method for successively introducing water soluble fibers into natural fibers (e.g. cotton) to produce a hollow and ultra soft structure, by introducing water soluble slivers into the center of a multi-hole feeder with multiple cotton fiber slivers arranged around the water soluble fiber in a pre-drawing process via a multi-hole sliver feeder. A cloth, e.g., made using the method.

摘要： A nonwoven web material including fibers formed of a polyolefin and a polyester is disclosed. The fibers may include fine fibers produced by, for example, a meltblowing process. The polyolefin may be polypropylene and the polyester may be polylactic acid. The polylactic acid may be obtained and included by recycling scrap nonwoven material containing a polylactic acid component, hydrolyzing the polylactic acid component to reduce its viscosity, blending the hydrolyzed polylactic acid with a polyolefin resin, and melt-spinning the blended material to form fibers. A related process is disclosed.

摘要： Disclosed are multicomponent fibers derived from a blend of a sulfopolyester with a water non-dispersible polymer wherein the as-spun denier is less than about 6 and wherein the water dispersible sulfopolyester exhibits a melt viscosity of less than 12,000 poise measured at 240° C. at a strain rate of 1 rad/sec, and wherein the sulfopolyester comprising less than about 25 mole % of residues of at least one sulfomonomer, based on the total moles of diacid or diol residues. The multicomponent fiber is capable of being drawn at a relatively high fiber speed, particularly at least about 2000 m/min, and may be used to produce microdenier fibers. Fibrous articles may be produced from the multicomponent fibers and microdenier fibers. Also disclosed is a process for multicomponent fibers, nonwoven fabrics, and microdenier webs.

摘要： A device and method for spinning polymer fibers utilizes one or more independent sources of polymer materials, pumps for feeding polymer material from each of the sources, and a series of distribution plates with surface grooves, through holes and/or slots together defining separated distribution paths, each of which receives polymer material from one of said independent sources. The surface grooves are defined to a depth less than the thickness of the distribution plate. At least one distribution plate contains spinneret orifices defined by outlet surface grooves extending from the distribution path to the edge of that plate, whereby fibers are extruded from the spinneret orifices edgewise from the plate. The spinneret orifices may be defined by overlayed outlet surface grooves or slots defined in abutting plates.
