摘要： A process for forming a high loft, nonwoven web is disclosed. The process includes introducing a single molten polymer to a die having a plurality of nozzles. Emitting the molten polymer through the nozzles to form a plurality of filaments. Using air streams to facilitate movement and drawing of the filaments. Directing the filaments, which are transformed into fibers, towards a pair of heated moving surfaces. The pair of heated moving surfaces forming a convergent passage having an entry and an exit. Depositing the fibers into the entry of the convergent passage and routing the fibers between the pair of heated moving surfaces in a machine direction to form a high loft, non-woven web. The web having a fiber size distribution of from 0 μm to about 15 μm with at least about 25% of the fibers being above 4 μm.

摘要： A hybrid non-woven web is disclosed which is a matrix of a stream of fibers of a first material joined to streams of first and second spun-blown fibers. Each of the first and second spun-blown fibers are formed from a thermoplastic composition that contains at least one polymer having a melt flow rate of from between about 5 grams/10 minutes to about 6,000 grams/10 minutes at 230° C. Each of the first and second spun-blown fibers also have an average diameter of between about 1 microns to 10 microns and a standard deviation of from between about 0.9 microns to about 5 microns. In addition, the hybrid non-woven web has a tensile strength of at least about 5 gf/gsm/cm width, measured in a machine direction. An apparatus and a method of forming the hybrid non-woven web are also disclosed.

摘要： An apparatus for making a high loft, non-woven web exhibiting excellent recovery is disclosed. The web has a 3-dimensional structure with fibers oriented in the x, y and z directions. The apparatus includes a die having 2 to 20 rows of nozzles with each row containing a plurality of nozzles. A pair of moving surfaces is located from a distal end of each nozzle. The pair of moving surfaces form a convergent passage. A pair of heaters is used to heat each of the pair of moving surfaces. A plurality of filaments are deposited onto the pair of moving surfaces and are routed through the convergent passage to form a 3-dimensional structure having two thin outer skins.
