    Abstract: A method for imparting permanent press properties to a textile containing cellulose fibers. The method involves applying an aqueous solution of a polysaccharide aldehyde and/or acetal at a pH of 1 to 8 to a textile, and heating the textile at a sufficient temperature for a sufficient time to react the polysaccharide aldehyde and/or acetal with the textile wherein water is removed from the textile, to impart permanent press properties to the textile. The method of the present invention provides permanent press properties to textiles treated therewith and increases the resistance of such textiles to future laundering abrasion. Such treated textiles display a significant reduction in wrinkles compared with nontreated textiles. Moreover, the treated textiles have a tactile sensation of feeling soft and retain their smoothness after laundering.

The reagent reacts under alkaline conditions with cellulose hydroxyl groups. A resin, e.g., polyester or vinyl resin, is then reacted with the thus modified cellulose fibers through the B-X substituent.

  • Patent number: 4877413
    Abstract: The invention relates to a process for the end-to-end dyeing of cellulosic materials, or blends that contain cellulose, with direct and/or reactive dyes by the pad dyeing process, which comprises using an aqueous liquor that contains at least one water-soluble direct or reactive dye and at least one water-soluble anionic, colorless organic compound having an affinity factor A, at a concentration of 0.2 to 0.3 g/l, for mercerized cotton of 1.1 to 4, said factor A being the quotient of the concentration of the water-soluble, colorless organic compound in a liquor without addition of dye, before impregnation, divided by the concentration of the water-soluble, colorless organic compound in the residual liquor without dye after impregnation. The process of this invention is suitable for dyeing textile cellulosic materials or blends containing cellulose to give end-to-end dyeings of good fastness properties.

  • Patent number: 4135877
    Abstract: A novel process for imparting durable antistatic and hygroscopic properties together with an excellent hand to fibers comprised of a high polymer having active hydrogen atoms in its molecule or fibrous structures made thereof is provided. The process is performed by heat treating such fibers or fibrous structures in the presence of a treating solution comprising at least one water-soluble vinyl monomer, acid and water. When the fibers impregnated with the solution are heated, the water-soluble vinyl monomers are graft polymerized with the fibers. The fibers are considered to act as a polymerization initiator, so that the graft polymerization reaction according to the present invention, different from conventional processes, can be effected without the aid of any polymerization initiators such as persulfates or peroxides.
