  • Patent number: 4039282
    Abstract: A catalyst system composed of aluminum chlorhydroxide [Al.sub.2 (OH).sub.5 Cl] and hydrogen peroxide [H.sub.2 O.sub.2 ] is disclosed which through synergistic interaction of these components is highly efficient and effective in treatments of cellulose-containing textiles with formaldehyde-amide adduct crosslinking agents. Products with durable-press properties are produced through use of the new catalyst system in treatments employing flash curing conditions, i.e., short processing times at high temperatures, as well as in treatments employing curing temperatures down to 130.degree. C. with longer processing times. Unlike previously known synergistically activated catalyst systems based upon Al.sub.2 (OH).sub.5 Cl, the presently disclosed system utilizes the combination of Al.sub.2 (OH).sub.5 Cl with H.sub.2 O.sub.2, an oxidizing agent, rather than with an acid or a salt with latent acidic or Lewis acid properties.

  • Patent number: 4032293
    Abstract: Strong base quaternary ammonium cellulose derivatives prepared under anhydrous conditions are further chemically modified in selected organic solvents by a sequential process that produces a partial cellulose ether in fibrous form that can be used in electro-chemical reactions covering a range of oxidation-reduction potentials. These new derivatives can be prepared such that they stabilize a given anion in the cellulose matrix until such time as its oxidation or reduction power is needed in desired chemical reactions. Although prepared in nonaqueous media, these red-ox cellulosic anion exchangers can be used to regulate oxidation-reduction reactions in aqueous media. Some of these new red-ox anion exchangers are dispersible in water and can be reprecipitated by organic solvents without losing their red-ox abilities during the process. Others are water insoluble.

  • Patent number: 4030280
    Abstract: By combination and interaction of aerodynamic and mechanical forces, textile fibers are removed from a single source, transported, collected, blended, subdivided, and distributed in equal amounts to multiple remote locations, whereby the fibers are continuously assembled into uniform ribbons for subsequent textile processing or supplied directly to open-end spinning units.

  • Patent number: 4028872
    Abstract: By combination and interaction of mechanical and aerodynamic forces, textile fibers in the form of tufts are processed continuously by deposition into a hopper, subjected to an initial tuft-opening and cleaning apparatus, discharged as smaller tufts into another hopper wherein a constant level is maintained. The smaller tufts are then continuously formed into a lap and fed to a secondary opening and cleaning apparatus. Fibrous stock is pneumatically doffed and conveyed from this single source through a blending, subdividing and distributing means, in equal amounts through conduits to multiple remote locations for continuous assemblage into identical fibrous ribbons, fed to fiber individualizing means and subsequently to open-end spinning units for further processing into yarn.

  • Patent number: 4029533
    Abstract: Glasslike materials have been produced by heating plumbite-treated cellulosics in a limited oxygen atmosphere while in contact with a glass or ceramic surface. Cotton-lace, knits, and other designs of cellulosic materials can be applied to glass or ceramic surfaces by process of this invention. Glass or ceramic materials have been joined together to form a strong bond by placing a piece of the plumbite-treated cellulosic material between the glasses and heating the assembly in a limited oxygen atmosphere. Etching of glass has also been achieved by process of this invention.

  • Patent number: 4024099
    Abstract: Acidic monomers are polymerized in aqueous solutions containing a free radical initiating catalyst and a methylol amide reagent or formaldehyde. The resulting acidic polymers have very high molecular weight as measured by the viscosities of dilute solutions of the acidic and neutralized polymers. The reaction solutions can be used to form tough, insoluble films, and the polymers can serve as effective thickening agents and floculating agents.
