    摘要： An in-line formed, non-laminated web is suitable for use as a composite fluid distribution and fluid retention layer in a disposable absorbent article. The web can be formed by selective deposition of airlaid materials including absorbents, such as pulp and superabsorbents, together with binder fibers. The web so constructed will have a plurality of intermingled lower basis weight areas and higher basis weight areas coexisting and distributed in at least a central region of the web, the alternations crossing the X axis or Y axis, or both, of the web, with the higher basis weight areas being a greater thickness in the Z-direction than the lower basis weight areas. The web so constructed will further have no discrete material boundaries between the lower basis weight stripes and the higher basis weight stripes. Further the necessity of later processing on the web to achieve a ridged structure is removed and the fibers will remain whole and undisturbed. The selective vacuum manipulation in conjunction with multiple fiber deposition heads, and appropriate timing of fiber addition therefrom, will yield a variety of useful composite webs having multiple layers thereby forming an economical single web which may be easily incorporated into an absorbent garment or article.

    摘要： Nonwoven web comprising thermoplastic meltblown fibers or filaments predominantly present as agglomerates or multiple fused fiber areas. Such agglomerates in the web act as columns and impart a desired degree of strength and resistance to compaction. In contrast to prior art webs where such agglomerates have been considered undesirable, the webs of the present invention find particular utility when formed into cylinders as filter plugs for smoking articles. In smoking articles of the invention, the filter plugs have a desired pressure drop while demonstrating an unexpected degree of firmness, all at an economically attractive cost. Preferred embodiments include those where the machine direction strength to cross machine direction grab tensile ratios in the range of from about 1:1 to 4:1 and the fibers or filaments are made from polypropylene. Other embodiments include webs and filter plugs containing additives distributed throughout the web.

    摘要： There is disclosed a method of adding flavorant to cigarette filters. A cigarette filter is made by forming a filter web using non-woven web comprising thermoplastic meltblown fibers of filaments that are present as fused agglomerates in a number fraction exceeding 33 percent and wherein a majority of fiber crossings of agglomerates are weld points; adding tobacco extracts to the filter web such that the filter web contains between 10% and 110% tobacco extracts by weight of the filter web; adding glycerin or a glycerin-water mixture to the thus treated filter web; and forming the thus treated filter web into a rod.
