An aqueous dispersion-type fluorine-containing water- and oil-repellent wherein (A) a fluorine-containing copolymer of (A-1) a monomer having a polyfluoroalkyl group and (A-2) a monomer copolymerizable therewith is dispersed in the presence of (B) a emulsifier containing a fluorine-containing cationic surfactant, is excellent in fastness to rubbing.
Abstract:
A novel starch used in a size composition is disclosed. The novel starch is a quaternary ammonium ether and acyl ester of starch which has a DS of quaternary ammonium ether of between 0.02 to 0.2 and a DS of acyl ester of between 0.01 to 0.3. The size composition is made from the novel starch and polyvinyl alcohol in a ratio of starch: polyvinyl alcohol of between 1:9 to 10:0. The method of making the size composition and the method of applying the size composition to the yarn is disclosed.
Abstract:
A process for photochemical stabilization of non-dyed and dyed polyamide fibre material and mixtures thereof with other fibres which comprises treating the fibre material with a fibre-reactive copper complex of bisazomethines prepared from, for example, salicylaldehydes and aliphatic diamines is described. Some of these copper complexes used are novel compounds. The polyamide fibre material, for example textile material, thus treated largely retains its extensibility and elasticity even after relatively prolonged exposure to light. In addition, a clear improvement in light-fastness is achieved in dyed material by treatment with the metal complex.
Abstract:
The level of released formaldehyde in a durable press treated fabric is significantly reduced or eliminated altogether by an oxidative aftertreatment process in which the fabric, after treatment with a formaldehyde-based durable press finishing agent and curing to impart durable press properties, is contacted with an oxidizing agent to destroy formaldehyde-releasing moieties present in the fabric. Preferably, the treatment of the durable press fabric with the oxidizing agent is carried out by impregnating the fabric with a solution containing the oxidizing agent and then providing the fabric a residence time in contact with the oxidizing agent to allow for reaction of the oxidizing agent with the formaldehyde-releasing moieties.
Abstract:
Textiles are rendered flame retardant by incorporating a phosphorus flame retardant prepared by a two step process having as essential steps:(1) reacting diorgano organophosphonate with reactant comprising phosphorus oxide reagent to yield a metaphosphate/phosphonate reaction product, and thereafter;(2) reacting the reaction product of step (1) with reactant comprising epoxide to yield poly (oxyorganophosphate/phosphonate) product.Selected poly (oxyorganophosphate/phosphonate) products contain a backbone structure of repeating units represented by the average formula: ##STR1## wherein m is an integer from 1 to 50; R, R.sub.1, and R.sub.2 are individually selected from saturated hydrocarbon radical, alkaryl radical, aralkyl radical, and aryl radical; and R.sub.3 is: ##STR2## wherein R.sub.4, R.sub.5, R.sub.6, and R.sub.7 are individually selected from hydrogen atom, hydrocarbon radical, and halogenated hydrocarbon radical.Articles and compositions such as textiles and polyurethanes are rendered flame retardant by incorporation of poly (oxyorganophosphate/phosphonate) products of Formula (I).
Abstract:
An aluminum acetate salt solution containing sodium and chloride ions is prepared by reaction of aqueous aluminum chloride and sodium acetate. It is suitable for use as a catalyst in the treatment of cellulosic-containing textiles with formaldehyde or a formaldehyde-amide adduct crosslinking agent to produce durable press properties in the finished material. There is no discoloration in the thus-treated fabric which also exhibits greater strength than is normally present in fabric treated to the same level of wrinkle resistance with an aluminum salt catalyst.
Abstract:
A process is provided wherein the thermal stabilization of an acrylic fibrous material is accelerated by heating in an oxygencontaining atmosphere following treatment while in contact with an aqueous solution wherein a substantial quantity of molecular oxygen is generated in intimate association with the fibrous material through the catalyzed decomposition of hydrogen peroxide. The resulting stabilized fibrous materials are nonburning when subjected to an ordinary match flame, and may be utilized as fire resistant textile fibers, or optionally converted to a carbonized fibrous material by heating in an inert atmosphere at a more highly elevated temperature.
Abstract:
Process for preparing a cross-linked cellulosic fabric capable of repeatedly absorbing optical brighteners from wash solution, comprising contacting the said fabric with an aqueous solution comprising a cross-linking agent, about 5-15 weight percent of an alkylpolyethylene oxide alcohol or glycol and thereafter curing the fabric.
Abstract:
TEXTILE ARTICLES OF CELLULOSIC FIBERS, OF NON-CELLULOSIC FIBERS AND COMPRISING BLENDS OF CELLULOSIC AND NON-CELLULOSIC FIBERS, WITH IMPROVED SOIL AND STAIN RESISTANCE QUALITIES, AND WITH MINIMISED ODOR AND TOXICITY IN THE FINISHED PRODUCT, ARE PRODUCED BY CONTACTING THE ARTICLES WITH CONVENTIONAL PRESS-FREE CREASE-RETENTION TERMOSETTING RESIN FINISH REACTANTS CONTAINING AN ALDEHYDE OR FROM WHICH AN ALDEHYDE IS RELEASED DURING POLYMERIZATION THEREOF, ANIMAL GLUE, AND A PLASTICIZER; AND BY CURING THE RESIN.
