Temperature adaptable fibers are provided in which a polyol/glyoxal based crosslinking system is used to create a water-insoluble polyacetal coating. The formaldehyde release properties characteristic of methylolamide finishing agents is avoided. The non-catalytic reaction utilizes stoichimetric amounts of sulfonic acids to derivatize the polyols which in turn react with the glyoxal to form a water-insoluble polymer. The material also possesses improved properties relating to soil release, durable press, resistance to static charge, abrasion resistance, pilling resistance and water absorbency.

Temperature adaptable glyoxal-modified fibers and method of preparing

Temperature adaptable textile fibers are provided in which phase-change or plastic crystalline materials are filled within hollow fibers or impregnated upon non-hollow fibers. The fibers are produced by applying solutions or melts of the phase-change or plastic crystalline materials to the fibers. Cross-linked polyethylene glycol is especially effective as the phase change material, and, in addition to providing temperature adaptability, it imparts improved properties as to soil release, durable press, resistance to static charge, abrasion resistance, pilling resistance and water absorbency.

Cellulosic materials, such as cotton fabrics, can be colored insitu by first treating the fabric with N-phenyldiethanolamine and a crosslinking agent for cellulose, such as dimethylol dihydroxyethyleneurea. After the fabric has been cured it is then colored by treating with sufficient concentrations of nitrous acid to form the colored nitroso derivative of the tertiary aromatic amine. The colors obtained are shades of green and yellow which are determined by: concentration of the N-phenyldiethanolamine; type of crosslinking agent; strength of the nitrous acid, and reaction times.

Method for insitu coloring crosslinked cellulosic materials

This invention relates to the transfer printing of cellulosic fabric by in situ polymerization of monomers to form polyamides and polyesters. The process involves treating the fabric with a diamine or bisphenol and then treating with a diacid chloride, drying, rinsing with neutralizing agent, and then heat transfer printing the fabric after drying. The reverse procedure can also be employed in which case the fabric is treated initially with the diacid chloride.

Process for modifying cellulosic fabrics for improved heat transfer

A process is disclosed for producing dyed fabrics by treating cotton with inorganic phosphorylating agent, curing, and then dyeing to develop the pattern.

Process for producing chambray and other dyed fabrics through

This invention relates to the preparation and use of durable press fabrics with strong acid grafts. The preparation is accomplished by the incorporation of a reactive hydroxyalkyl sulfonic or phosphinic acid in a crosslinking finishing system. As a consequence of this, durable press fabrics are produced with sulfonic or phosphinic acid grafts. Because of these strong acid grafts, these fabrics show improved moisture regain properties, can be dyed with basic dyes, can be whitened with basic optical brighteners and have ion exchange properties for metallic cations.

Process for producing and utilizing durable press fabrics with strong

This invention relates to fabric treatments by which cotton and cellulosic blended fabrics can be provided with wrinkle resistance (smooth dry performance) and color at the same time. In particular, it provides a means by which cellulosic fabrics can be dyed with basic dyestuffs. In addition to a conventional means by which the entire fabric can be dyed with a basic dye, variations are achieved in which one side of the fabric is dyed one color and the other side of the fabric is dyed a second color. The color on the reverse side can be provided by means of either basic dyes or regular cotton dyes. The technique has also been extended for the printing of fabrics.
