A method of cleaning residue from a surface using a disposable cellulosic wiper that includes from about 25% or more by weight of pulp-derived papermaking fibers. The pulp-derived papermaking fibers have a characteristic scattering coefficient of less than 50 m2/kg. The wiper also has from about 25% to about 75% by weight of fibrillated regenerated independent cellulosic microfibers. The fibers are finer than 14 mesh, have a characteristic Canadian Standard Freeness (CSF) value of less than 175 ml, have a number average diameter of less than about 2 microns, and are present in amounts such that the wiper exhibits a scattering coefficient of greater than 50 m2/kg. The wiper is applied, with a predetermined amount of pressure, to a residue-bearing surface. The surface is wiped with the applied wiper to remove residue from the surface, such that the surface has less than 1 g/m2 of residue after being wiped.

A quaternary ammonium halide is prepared by reacting a substituted or unsubstituted haloalkane with a tert-amine in a mol ratio not higher than 1.1/1 in the absence of a solvent and at a temperature such as to maintain the reaction mixture liquid.

A method of and apparatus for attaching a spout to a planar portion of an article such as a milk or juice carton, which may be integrated into conventional carton forming and filling machines, includes the steps of heating a stem of a spout, applying a bonding agent to a flange on the spout, positioning the spout in a predetermined relation to a spout applicator, positioning a carton with a hole provided in a predetermined relation to the spout applicator and attaching the spout to the carton where the heated stem is deformed to mechanically engage the carton about the hole. An apparatus to accomplish the method is also disclosed.
摘要:
A method and apparatus for attaching a spout to a planar portion of a container, such as a milk or juice container, which may be incorporated in a conventional conveyor line. The method includes the steps of successively positioning the container at three stations, first, where a hole is punched, second, where a bonding agent is applied, and third, where the spout is installed on the container. An apparatus for carrying out the method includes mechanisms for positioning the container at each station relative to an edge of the container so that the operation can be performed on the container.

A nonwoven fibrous web is disclosed having high wet tensile strength when packed in a preservative liquid load, yet which breaks up under mild agitation conditions in a wet environment such as by the flushing action of a toilet. The wiper includes a nonwoven web made of a special blend of cellulosic fibers held together only by friction and naturally occurring hydrogen bonding. No binder is necessary to hold together the fibers. Derivatization of the fibers is not necessary for their breakapartability. The nonwoven fibrous web is produced by subjecting a wet-laid web of cellulosic fibers to hydroentanglement and drying the web without addition of a bonding agent.

A multi-ply bath tissue having no more than three plies and no fewer than two plies. The multi-ply tissue has a basis weight of from about 20 to about 35 lbs per 3000 sq foot ream and includes from about 3% to about 50% cellulosic microfiber, from about 50% to about 97% wood pulp fibers, has a geometric mean (GM) dry tensile of from about 17 to 80 g/3 in. per pound of basis weight, a cross-machine direction (CD) dry tensile of between about 30 to about 60 g/3 in. per pound of basis weight, and sufficient temporary wet strength resin to provide an initial Finch Cup CD wet tensile of from about 2.5 to about 20 g/3 in. per pound of basis weight. The initial Finch Cup CD wet tensile decays to less than 65% of the initial value in less than fifteen minutes after immersion in water. The product has a caliper of at least 5 mils per 8 sheets per pound of basis weight.

摘要:
Certain substituted phenolic compounds when used with or without 1,2-epoxides as the sole stabilizer components are very effective in stabilizing n-propyl bromide (NPB). In a standard commercially important 60° C. stability test, representative substituted phenolic compounds used pursuant to this invention, can enable NPB to pass the test even though present at levels of about 50 ppm (wt/wt) or less in NPB containing no other stabilizer additive component. In fact, amounts as low as 1 ppm have been found effective with various substituted phenolic compounds. In addition, it has been found that one of the preferred stabilizers of this invention—2,6-di-tert-butyl-p-cresol—even though higher boiling than NPB, left inconsequential amounts of residue at least throughout the range of 1 to 30 ppm (wt/wt). Also, it has been found that certain other preferred stabilizers of this invention can provide synergistically improved stability in passing the 60° C. stability test when used with at least one 1,2-epoxide, notably butylene oxide.
