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.

The present invention discloses a disposable cleaning product for use in household cleaning or personal care applications. The cleaning product of the invention is a multi-layer laminate product and may include at least two distinct layers, an abrasive layer and an absorbent layer. The absorbent layer contains a sponge-like member optionally in combination with a plurality of cellulosic fibrous webs. The sponge-like member can be made from various materials. For example, in one embodiment, the sponge-like member comprises one or more layers of a spunbond web containing crimped, bicomponent filaments.

A water-solible polymer dispersion, p process for producing the same and a method of use therefor. In particular, the water-soluble polymer dispersion is one comprising water-soluble polymer fine particles of 100 μm or less diameter having at least one ionic property selected from among cationic, amphoteric, nonionic and anionic properties together with a polyalkyleneimine and/or a product of polyalkyleneimine modification wherein according to necessity an appropriate amount of water-soluble inorganic salt is incorporated. The provided process enables easily performing the production in dispersed form by means of production facilities of low cost. The obtained water-soluble polymer dispersion is excellent in storage stability and exhibits satisfactory fluidity and solubility so as to enable use in papermaking raw material pretreatments added to papermaking raw materials prior to machine operation and also for enhancement of freeness, increase of sizing degree and enhancement yield. Further use can be found in incorporation in an organic sludge or paper mill sludge for flocculation and ensuing drainage.

A magneto-electric dialysis process for desalinating seawater, preparing salt from seawater and desalting industrial water is characterized by that on the basis is existing electric dialysis equipment, a static magnetic field is additionally used to directionally shift the cations and anions in flowing solution. Its apparatus is composed of a casing with different water inlets and outlets and electrodes, a group of cationic exchange membranes and anionic exchange membranes, which are alternatively arranged between anode and cathode, and a permanent magnet attached to each wall of the casing. Its advantages are high throughput, less electric consumption and not scaling.

The invention discloses a corrugated paper production method using waste paper pulping to improve the fiber utilization rate. The method comprises the following steps: waste paper pulp adjustment, waste paper pulp soaking and swelling, waste paper pulp puffing, waste paper pulp breaking, shredded kraft paper puffing, kraft paper pulp breaking, residue removal and screening, mixing with a grindingaid, grinding for forming a pulp, mesh papermaking pressing and subsequent papermaking. The waste paper and the shredded kraft paper are used to produce the corrugated paper, and the papermaking material is sufficiently preprocessed before the above pulp breaking step to maximally dissociate fibers in the papermaking material in the pulp breaking step and keep the integrity of the fibers, so the utilization rate of secondary fibers in the papermaking step is improved. The method has the advantages of simple process, energy-saving, environmentally-friendly, clean and pollution-free production process, great reduction of fiber damages and the broken rate of the fibers in the pulping process, and high fiber utilization rate, and the toughness and the strength of the prepared corrugated paperare greatly improved.

There is provided an endoglucanase enzyme, which is useful for reducing fuzz of regenerated cellulose-containing fabrics, improving the touch and appearance, color clarification, localized variation in color, reducing stiffness and using it as components of a detergent, as well as deinking waste paper and improving freeness of paper pulp. A cDNA coding for the endoglucanase enzyme NCE5 was cloned and its DNA sequence and amino acid sequence derived from it were determined.

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, (W_1/2h)_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.

The invention provides a complex enzyme preparation for extracting a maize yellow pigment and an extraction method. The complex enzyme preparation comprises the following components in percentage by mass: 1 to 5% of cellulase, 5 to 10% of beta-mannase, 2 to 8% of xylanase, 10 to 20% of protease, 2 to 8% of lipase, 10 to 20% of alpha-amylase, 5 to 10% of glucoamylase, 1 to 5% of pectinase, 1 to 5%of glucosaccharase and the balance of water. The complex enzyme preparation for extracting the maize yellow pigment and the extraction method are simple in process and convenient to operate; enzymolysis preprocessing is carried out on corn gluten meal by adopting a biological enzyme method, macromolecular substances such as polysaccharides, proteins, pectins and the like which are connected with the maize yellow pigment are degraded, simultaneously, network structures of the proteins are hydrolyzed so as to improve freeness of the maize yellow pigment and make the maize yellow pigment easier to extract, and moreover, after enzymolysis processing, the maize yellow pigment and zein are separated by adopting two ethanol solutions with different concentration so as to obtain the high-purity maize yellow pigment; and an extraction rate of the maize yellow pigment can be up to 7.39%.

This invention provides a method for producing paper and cardboard, corresponding to paper-making facilities in which an acidic paper-making process and a neutral paper-making process are intermingled, without collapsing the formation in both of the acidic paper-making and neutral paper-making and improving water filterability and yield. This method for producing the paper and cardboard is provided by adding a branched or cross-linked amphoteric polymer, water soluble anionic polymer and/or anionic organic polymer fine particles or water soluble cationic polymer to a paper stock, making it a sheet form by dehydration and then drying.

The invention relates to natural-color straw pulp with improved tearing index, freeness and folding strength, and stable performance, in particular to natural-color straw pulp and application thereof in mixed pulp and paper products. The straw pulp has the advantages that: color phase or whiteness of the straw pulp is remarkably improved; the bulk and air permeability are high; and the acquired data of the sizing agent of the natural-color straw pulp is more stable because of small quality fluctuation of sizing agent.
