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.

The present invention discloses a disposable meltblown scrubbing product for use in household cleaning or personal care applications and an abrasive aggregate fiber which may be utilized in the scrubbing product. The meltblown web is formed primarily of polymeric fibers in a disordered or random distribution as is typical of fibers deposited in meltblown processes so as to form an open, porous structure. The aggregate fibers of the present invention generally are formed of two or more separate abrasive polymer fibers or strands which are adhered together along at least about 5 mm of the fiber length. The abrasive fibers of the meltblown web are generally greater than about 15 microns in diameter.

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.

Fibrous cellulosic products incorporating both conventional cellulosic fibers and laterally expanded cellulose fibers exhibit exceptional porosity, bulk, absorbency and resiliency properties. Typical products include absorbent tissue products, absorbent fluff products and flat papers. The laterally expanded cellulose fibers exhibit: (i) a broadened X-Ray diffraction peak for the most prominent reflection having a width at half-height, (W1 / 2h)A, of at least about 3.0° 2Θ, (ii) broad overlapping maxima in their Raman spectrum between 285 and 500 cm−1, the height of the two tallest of said maxima in said spectrum between 285 and 500 cm−1 being between 35 and 50% of the height of the peak near 1098 cm−1 and (iii) a blue stain when treated with Graff C-stain, the stain exhibiting less red than the stains exhibited with bleached hardwood kraft fibers and bleached softwood kraft fibers.

To provide a system for processing program information in which the display structure of a program table can freely be changed in accordance with a requirement or a taste of an audience, the system for processing program information is constructed to include program information storage means 1 for storing program information, and program table display means 4 for two-dimensionally displaying a program table following two axes in accordance with two attributes 102 and 103 among attributes given to each piece of program information, to make the program table 101 for two-dimensionally displaying programs with two axes of free attributes. For the audience, program tables of various constructions can be displayed on the display means at will and in respective program retrieval operations, the program table easy to look for a program can be obtained. An objective program can be found in a short time by coming up with ideas for the extraction of the program or the like, and this is useful for making a broadcast view plan of himself.
