摘要:
A process for the treatment of a synthetic textile (T) with a cationic biocide (B) and at least one anionic polymer (P) which comprises the step of treating the synthetic textile with an aqueous composition containing the cationic biocide (B) in a concentration (c1) and containing the anionic polymer (P) in a concentration (c2), wherein the concentrations (c1) and (c2) are selected so that the ratio (R) of negative charges of the anionic polymer (P) to the positive charges of the cationic biocide (B) is between 10 : 1 and 1 : 1, leads to textiles with long term biocide activity.
摘要:
Compositions based on blends of certain specified poly(vinyl alcohol) copolymers and various starches are described which are useful as sizes, and can have improved ability to be desized from fabrics compared with the starches alone. The specific poly(vinyl alcohol) copolymers useful in the blends with the starches are copolymers having a high level of acrylic ester comonomer. The blend sizes are useful in producing woven materials since they are excellent sizes, and are uniquely adaptable to caustic desizing.
摘要:
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.
摘要:
A textile is treated with a processing composition comprising (1) a water-soluble polymer having carboxyl groups and (2) a crosslinking agent having at least two groups reactive with the carboxyl groups before processing the treated textile with a cationic emulsion.
