Abstract:
This invention relates to a durable press treatment for textile fabrics containing cellulosic fibers and which is characterized by avoiding the use of formaldehyde and problems associated therewith. The fabric is impregnated with a formaldehyde-free finishing agent containing glyoxal, reactive silicone and a catalyst. The fabric is thereafter dried and the finishing agent is cured to impart durable press properties to the fabric.
Abstract:
Textile materials containing cellulosic fibers are provided with durable press properties by reacting and crosslinking the cellulosic fibers with a durable press finishing agent consisting essentially of a silicone compound and a silicone fragmentation reactant in an effective amount to fragment the silicone compound when exposed to curing conditions. The fabric is impregnated with a finishing bath containing the durable press finishing agent and the fabric is heated to fragment the silicone compound and react and crosslink the finishing agent with the cellulosic fibers to impart durable press properties to the fabric.
Abstract:
A soil-release composition for the treatment of textile fabrics comprises a complex of a nonionic detergent and a polycarboxylate polymer, together with an organic quaternary ammonium surfactant compound in a concentrated aqueous solution with an acid pH.
Abstract:
A process is provided for modifying the surface characteristics of a carbonaceous fibrous material (i.e., either amorphous carbon or graphitic carbon) and to thereby facilitate enhanced adhesion between the carbonaceous fibrous material and a matrix material. The carbonaceous fibrous material is coated with a compact polyphenylene polymer coating which is deposited thereon upon contact with an excited gas species generated by applying high frequency electrical energy in pulsed form to an inert gas in the presence of at least one aromatic compound. The coating step is efficiently conducted at a temperature of about 0* to 150*C. and at a pressure within the coating zone of about 1 to 3 atmospheres. Composite articles of enhanced interlaminar shear strength may be formed by incorporating the fibers modified in accordance with the present process in a resinous matrix material.
Abstract:
POLYOXYMETHYLENE ARE DISPERSED IN WATER BY SUSPENDING POLYOXYMETHYLENE PARTICLES IN WATER AND THEN COMMINUTING THE PARTICLES OF THE SUSPENSION, THE POLYOXYMETHYLENE THUS BEING DIRECTLY DISPERSED. FOR THE DIRECT DISPERSION THERE ARE USED POLYOXYMETHYLENES HAVING HYDROPHILIC GROUPS, FOR EXAMPLE, CARBOXYLATE GROUPS. AQUEOUS POLYOXYMETHYLENE DISPERSION THUS PREPARED ARE SUITABLE FOR THE PREPARATION OF COATINGS, IN PARTICULAR FOR PAPER AND TEXTILES.
Abstract:
This disclosure relates to a method for imparting durable press characteristics to textile fabrics containing cellulosic fibers. The fabric is impregnated with a homogeneous composition comprising a volatile liquid carrier and certain methoxylated, phenyl-substituted fluid organosilicon polymers, and is subsequently heated to effect crosslinking of the fluid organosilicon polymers.
Abstract:
Described are detergent-compatible antistatic compositions produced by the at least partial complexing of certain anionic complexing components and particles of an intimate mixture of quarternary ammonium compounds and organic dispersion inhibitor materials. The complex formed, which is relatively water-impenetrable and insoluble, constitutes at least 25% of the surfaces of the particulate detergent additive of this invention. These compositions provide static control benefits in laundering operations at reduced antistatic levels.
