Disposable scrubbing product
InactiveUS20050130536A1High yieldResists effect of waterPersonal careCarpet cleanersEngineeringFibrous layer
The present invention discloses a disposable scrubbing product for use in household cleaning or personal care applications. In one embodiment, the present invention is directed to a cleaning tool including a handle and a rigid base to which the scrubbing product of the present invention may be attached to form a convenient cleaning tool. The scrubbing product of the invention is a multi-layer laminate product and generally includes at least two distinct layers, an abrasive layer and an absorbent fibrous layer such as a layer tissue made from papermaking fibers, a layer of coform, an airlaid web, or combinations thereof. The abrasive layer is formed primarily of polymeric fibers in a disordered or random distribution as is typical of fibers deposited in meltblown or spunbond processes so as to form an open, porous structure. In one embodiment, the abrasive layer comprises multifilamentary aggregate fibers. In one embodiment, the absorbent fibrous layer is an uncreped, through dried paper web.

Chemical activation and refining of southern pine kraft fibers
InactiveUS20050061455A1Increase the pulp freenessEasy to drainPulp properties modificationPulp bleachingChemical treatmentCellulose fiber
A method for alteration of the morphology of cellulose fibers, particularly softwood fibers, by (a) subjecting the fibers to a metal ion-activated peroxide treatment carried out at a pH of between about 1 and about 9, preferably between 3 and 7, and (b) subjecting the treated fibers to a refining treatment thereby converts SW fibers to HW-like fibers in many respects. The metal ion-activated peroxide treatment has been noted to act on pulp cellulose and hemi-cellulose, causing oxidation and oxidative degradation of cellulose fibers. The chemical treatment of the pulp, taken alone, is not sufficient to attain the desired modification of the morphology of the fibers, however, subsequent refining or like mechanical treatment of the chemically-treated fibers to achieve a given degree of refinement of the fibers requires dramatically less refining energy to achieve a desired end point of refinement and to impart other desirable properties to the pulp. A pulp of modified SW fibers and a mixture of HW fibers and modified HW fibers are disclosed.

Method to Produce Composite-Enhanced Market Pulp and Paper
ActiveUS20200347549A1Enhanced market pulpHigh freenessPulp properties modificationNon-macromolecular organic additionFiberPolymer science
An improved market pulp and process for making the same by adding a composite material are described. The composite material includes cellulose nanocrystals, cellulose nanofibers, or another high aspect ratio, high surface area cellulose material (or a starch, or both) and a crosslinking compound that crosslinks a portion of the surface hydroxyl groups to form a 3-D matrix. Adding the composite material to market pulp has been shown to improve the strength of twice-dried paper products, made from such an enhanced market pulp. By crosslinking a portion of the surface hydroxyl groups in the market pulp to form a 3-D matrix, a first drying step may be accomplished without loss of benefits afforded when the market pulp is later re-pulped to make a paper product.
