摘要:
A method for producing a natural fiber part may comprise applying an aqueous solution of an inorganic aluminum salt to the natural fiber part and drying the natural fiber part applied with the aqueous solution. The aqueous solution may contain the aluminum salt in a concentration of 2 to 40% by weight. The aluminum salt may include an alum compound. At least one of an inorganic thickening agent or an inorganic stabilizing agent may be added to the aqueous solution.
摘要:
The present invention is directed to an absorbent material and the fibers therein, having two or more layers including an upper surface layer which has on the outer surface of the layer one or more surface area zones which are more wettable zones and adjacent thereto one or more less wettable zones, where the more wettable zones have a greater hydrophilicity than the less wettable zone. The present invention is also directed to the fibers therein, which contain polyvalent cation-containing compounds and fatty acid containing compounds. The present invention also provides for methods of treating fibers or solid materials and processes of producing the hydrophobic materials.
摘要:
The invention relates to a phosphorus-containing flame retardant formulation for cellulose-containing moldings, comprising from 0.1 to 99.9% by weight of a resin of an organic nitrogen compound and from 0.1 to 99.9% by weight of a phosphorus-containing flame retardant.
摘要:
Malodorous substances resulting from the decomposition of organic products derived from living organisms, such as acrolein, ammonia, aldehydes, cadaverine, indole, alkaloids including primary and/or secondary amines, butyric acid and skatole, separately or in combination, which may be included in polluted air escaping from rendering plants or cooks, poultry and seafood processing plants, food canneries, tanneries, sewage treatment plants or excrement receptacles, or which may be carried by or impregnated in fabrics, can be rendered unobjectionable by treatment of such air, facilities or products with metallic material including inorganic metal salts such as chlorides, sulfates, nitrates and phosphates, oxides and hydroxides. Suitable metals include aluminum, copper, iron, nickel and zinc. Usually the metallic material is carried by or contained in a liquid vehicle, but in some instances may be used in powder form. Also, in some instances, it is desirable for the liquid vehicle to be nonneutral, having a pH of 7 plus or minus at least 2, and preferably alkaline having a pH of at least 11.
摘要:
A method for strengthening long chain synthetic polymer fibers involves soaking a fibrous material in a treatment solution of potassium aluminum sulfate or ammonium aluminum sulfate, or both, in water. The treated material is immersed in a fixing solution containing a water soluble metallic carboxylate such as sodium or potassium stearate, and then rinsed with a nonreactive liquid.
摘要:
A flame and smolder resistant cellulosic insulation material, method of tting loose-fill cellulosic material, and composition for imparting flame and smolder resistance to such materials are disclosed with the combination of from about 2 to 9% sulfur and from about 10 to 25% flame retardant uniformly distributed in the cellulosic insulation material based on the weight of cellulosic material.
摘要:
A method of inhibiting or reducing the undesirable growth properties of a resilient flooring product having a fibrous cellulosic backing which comprises: substantially uniformly incorporating in the fibrous cellulosic backing of a resilient flooring product from about 0.05% by weight to about 4% by weight, based on the weight of the fibrous cellulosic backing, of a growth inhibitor from the group consisting of alums, aluminum sulfate, and mixtures thereof; and installing the resilient flooring product on a surface coated with a water-based adhesive while the fibrous cellulosic backing contains such percentages of the growth inhibitor, whereby undesirable growth, swelling, buckling or the appearance of bubbles in the resilient flooring product is inhibited or reduced, even when the installation takes place at low relative humidity conditions below about 50% relative humidity. The resulting cellulose-backed resilient flooring products having reduced growth properties are also included in the scope of the inventive concept.
