摘要： An improved method of making reconstituted tobacco using a dry-forming process. Fiberized tobacco stems and scrap are combined with tobacco material of a fine particle size. The resulting tobacco mixture is conveyed in an airstream and deposited on a moving foraminous surface. An adhesive is incorporated into or applied to the web bonding the tobacco particles into a coherent sheet, and the sheet is dried if necessary. The dried sheet may be divided into leaflets or shredded for further processing as reconstituted tobacco. In preferred embodiments, cellulose fibers are mixed with the tobacco particles prior to web formation to impart increased sheet strength. In a further embodiment tobacco fines are mixed with the adhesive and applied to the web in the adhesive composition. Results obtained by means of the present invention include cost savings particularly in terms , of reduced capital costs. Because the tobacco is used substantially in its natural state, the aroma and other desirable tobacco attributes are retained.

摘要： Nonwoven web comprising thermoplastic meltblown fibers or filaments predominantly present as agglomerates (32) or multiple fused fiber areas (34). Such agglomerates (32) 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.
摘要翻译：主要作为附聚物（32）或多个熔融纤维区域（34）存在的热塑性熔喷纤维或细丝的非织造纤维网。纤维网中的这种附聚物（32）充当柱并赋予所需的强度和抗压缩性。与现有技术的网相比，其中这种附聚物被认为是不期望的，本发明的腹板在形成为气瓶作为吸烟制品的过滤嘴时具有特别的用途。在本发明的吸烟制品中，过滤塞具有期望的压降，同时表现出意想不到的坚固度，所有这些都以经济上有吸引力的成本。优选的实施方案包括其中机器方向强度与机器方向抓取拉伸比在约1:1至4:1范围内并且纤维或长丝由聚丙烯制成的实施方案。其他实施方案包括含有分布在整个幅材上的添加剂的纸幅和滤嘴。
