Cigarette filters are disclosed which comprise entangled continuous filaments of lyocell. The filaments may be entangled for example by hydroentangling a web which comprises one or more layers of lyocell filaments in spread tow form or by directing radial or circumferential water jets at a tow of lyocell filaments in rod form.

Nonwoven articles having high durability and absorbent-characteristics, and their methods of manufacture, are presented. One preferred article is characterized by (a) a nonwoven web comprised of organic fibers comprised of polymers having a plurality of pendant hydroxyl groups; and (b) a binder comprising an at least partially crosslinked and at least partially hydrolyzed polymeric resin having a plurality of pendant resin hydroxyl groups, the resin crosslinked by a crosslinking agent, the cross...

A diaper or other absorbent article may include an absorbent body comprising in sequence from the top (the surface adjacent the wearer's body). An upper assembly (2, 3, 4, 5) comprising an acquisition layer (3) formed of first fibrous material substantially free of superabsorbent material, a superabsorbent layer (5) consisting substantially only of first superabsorbent material having a Gel Layer Permeability value of at least about 4 ml/cm.sup.2 /sec and which is present in an amount of about 2...

A method of making an article by joining together at least two porous components is described, the method comprising the steps of making at least two generally tubular PM components to be joined in the axial direction, each component having an axial length less than that of the tubular article; the at least two components both having interconnected porosity and each having at least one mutual mating face; assembling the at least two components together so that the at least one mutual mating face...

A photochromic article comprising a host material and a photochromic amount of a photochromic compound or a structural isomer of the photochromic compound, the photochromic compound represented by the formula: ##STR1## wherein R.sub.1, R.sub.2, R.sub.4, R.sub.5, R.sub.6, R.sub.8, A, B, C, and D are each selected from the group consisting essentially of hydrogen, a stable organic radical, a heterocyclic group, halogen, a nitrogen-substituted radical, and a nitrogen-substituted ring radical.

A pack 10 of bottles 14 comprises a plurality of layers 12. Each layer 12 has its bottles 14 packed in a close packed side-by-side array, the array being hexagonal. The layers 12 are packed in a sleeve 18 of a plastics material. The sleeve 18 is selected to have a perimetral dimension slightly less than a peripheral dimension of each layer 12 such that the layers 12, once packed in the sleeve, are constrained against movement.

This invention provides a smoking article having reduced sidestream smoke in the inter-puff period. A smoking article according to the invention may comprise segments of a high level of tobacco-containing material interconnected by segments of low level of tobacco-containing material which are capable of maintaining smoulder in the inter-puff period and re-igniting the segments of a high level of tobacco-containing material in the puff period. Alternatively, a smoking article according to anothe...

Nonwoven particles having high durability and absorbent characteristics, and their methods of manufacture, are presented. One preferred article is characterized by (a) a nonwoven web comprised of organic fibers comprised of polymers having a plurality of pendant hydroxyl groups; and (b) a binder comprising an at least partially crosslinked and at least partially hydrolyzed polymeric resin having a plurality of pendant resin hydroxyl groups, the resin crosslinked by a crosslinking agent, the cros...

A high temperature corrosion resistant nickel-base alloy, e.g. for turbine stator blades in gas turbine engines, providing a good balance between mechanical strength, oxidation resistance and compatibility between a coating and a substrate. A preferred composition of the coating alloy, which composition also provides a good balance between sulphidation and oxidation corrosion, is: aluminum 25-30%; chromium 3-14%; tantalum 7-9; yttrium 0.01-0.5%; nickel remainder. An article may be provided in wh...

This invention provides a smoking article having reduced sidestream smoke in the inter-puff period. A smoking article according to the invention may comprise a lengthwise, axially extending, tobacco-containing or non-tobacco fuse portion which sustains smoulder in the inter-puff period when surrounding tobacco material is substantially extinguished and which re-ignites the extinguished material on puffing of the smoking articles.
