摘要： A technique for incorporating a liquid additive into a nonwoven web is disclosed. Specifically, the liquid additive is loaded into filler particles to form a “dry liquid concentrate”, i.e., pulverulent granular solid or powder loaded with the liquid additive. The incorporation of the liquid additive into dry liquid concentrates provides a variety of benefits. For example, prior to extrusion, the dry liquid concentrates generally retain the properties of filler particles from which they are formed as the liquid remains isolated. In this manner, a higher level of the liquid additive may be compounded with a melt-extrudable base composition without adversely affecting the extrusion process. Only upon extrusion of the composition will a significant portion of the liquid additive be released to provide the desired properties to the resulting nonwoven web.

摘要： An elastic laminate capable of being rolled for storage and unwound from a roll when needed for use, includes an elastic layer of an array of continuous filament strands with meltblown deposited on the continuous filament strands, and a facing layer bonded to only one side of the elastic layer. The meltblown layer may include an elastic polyolefin-based meltblown polymer having a degree of crystallinity between about 3% and about 40%. The laminate suitably has an inter-layer peel strength of less than about 70 grams per 3 inches cross-directional width at a strain rate of 300 mm/min. Alternatively or additionally, the continuous filament strands and/or the facing layer may include an elastic polyolefin-based meltblown polymer having a degree of crystallinity between about 3% and about 40%. In certain embodiments, the elastic laminate may include an extensible facing layer bonded to an elastic or semi-elastic film layer having a basis weight of about 50 gsm or less, wherein the facing layer includes an elastic polyolefin-based polymer having a degree of crystallinity between about 3% and about 40%.

摘要： There is disclosed a nonwoven web for use as a barrier layer in an SMS fabric laminate. The web is formed at commercially acceptable polymer melt throughputs (greater than 3 PIH) by using a reactor granule polyolefin, preferably polypropylene, that has been modified by the addition of peroxide in amounts ranging from up to 3000 ppm to reduce the molecular weight distribution from an initial molecular weight distribution of from 4.0 to 4.5 Mw/Mn to a range of from 2.2 to 3.5 Mw/Mn. Also the addition of peroxide increases the melt flow rate (lowers viscosity) to a range between 800 up to 5000 gms/10 min at 230.degree. C. The resulting web has an average fiber size of from 1 to 3 microns and pore sizes distributed predominantly in the range from 7 to 12 microns, with a lesser amount of pores from 12 to 25 microns, with virtually no pores greater than 25 microns, and with the peak of the pore size distribution less than 10 microns.
