摘要:
An absorbent paper sheet includes cellulosic papermaking fiber and up to about 75 percent by weight fibrillated regenerated cellulose microfiber which may be regenerated from a cellulosic dope utilizing a tertiary amine N-oxide solvent or selected ionic liquids. Fibrillation of the microfiber is controlled such that it has a reduced coarseness and a reduced freeness as compared with unfibrillated regenerated cellulose microfiber from which it is made and provides at least one of the following attributes to the absorbent sheet: (a) the absorbent sheet exhibits an elevated SAT value and an elevated wet tensile value as compared with a like sheet prepared without fibrillated regenerated cellulose microfiber; (b) the absorbent sheet exhibits an elevated wet/dry CD tensile ratio as compared with a like sheet prepared without fibrillated regenerated cellulose microfiber; (c) the absorbent sheet exhibits a lower GM Break Modulus than a like sheet having like tensile values prepared without fibrillated regenerated cellulose microfiber; or (d) the absorbent sheet exhibits an elevated bulk as compared with a like sheet having like tensile values prepared without fibrillated regenerated cellulose microfiber.
摘要:
A fabric which can be made by a wet-laid process using crimpable bicomponent fibers is disclosed which may have a high bulk and/or elasticity. The fabric can be made by a high speed continuous process wherein the fabric is pulled from a Yankee dryer by a take off roll which rotates faster than the Yankee dryer.
摘要:
A spout is attached to a wall of an article, such as a paperboard container, by pushing a stem of a spout longitudinally through a pre-formed hole in the article and against an inclined face of a flare tool so that a portion of the stem is bent laterally outwardly and into the path of a staking tool. The staking tool is displaced so that the face thereof bends a laterally outer section of the bent portion against the wall of the article while leaving a laterally inner section of the bent portion spaced longitudinally from the wall.
摘要:
A method of making a belt-creped absorbent cellulosic sheet. A paper making furnish is compactively dewatered to form a dewatered web having an apparently random distribution of papermaking fiber orientation. The dewatered web is applied to a translating transfer surface that is moving at a transfer surface speed. The web is belt-creped from the transfer surface at a consistency of from about 30% to about 60% utilizing a generally planar polymeric creping belt having a plurality of perforations, under pressure, in a belt creping nip defined between the transfer surface and the creping belt. The belt travels at a belt speed that is slower than the speed of the transfer surface. The web is creped from the transfer surface and redistributed on the creping belt to form a web having a plurality of interconnected regions of different local basis weights. The web is then dried.
摘要:
A multi-ply wiper/towel product includes at least one wet laid web including at least 10% fibrillated cellulosic microfiber, and at least about 40% wood pulp derived papermaking fibers. The at least one wet laid web has formed therein (i) a plurality of fiber-enriched hollow domed regions on the upper side of the at least one wet laid web having a relatively high local basis weight, and (ii) connecting regions of a relatively lower local basis weight forming a network interconnecting the relatively high local basis weight domed regions of the one wet laid web. Transition areas are provided in the at least one wet laid web with upwardly and inwardly inflected consolidated fibrous regions transitioning from the connecting regions into the domed regions, and the at least one wet laid web exhibits a differential pore volume for pores under 5 microns in a diameter of at least about 75 mm3/g/micron.
