摘要:
A method for imparting permanent press properties to a textile containing cellulose fibers. The method involves applying an aqueous solution of a (hydroxyalkyl)urea and/or a .beta.-hydroxyalkyl amide crosslinking agent to a textile, and heating the textile at a sufficient temperature for a sufficient time to react the crosslinking agent with the textile wherein water is removed from the textile, to impart permanent press properties to the textile. The crosslinking agent is free of formaldehyde. 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:
Durable press properties are imparted to a fabric by applying to the fabric an aqueous durable press treatment composition comprising a reactive modified ethylene urea resin, such as dimethylol dihydroxy ethylene urea (DMDHEU), a crosslinking acrylic copolymer derived from butyl acrylate and acrylonitrile and having a glass transition temperature (T.sub.g) of -30.degree. C. or lower, and a catalyst. The fabric is dried to a residual moisture content of 10 to 20 percent by weight, is pressed to remove unwanted wrinkles, and is heated at a temperature of 88.degree. to 175.degree. C. for up to fifteen minutes to cure and crosslink the durable press treatment composition and impart durable press properties to the fabric. The process can be applied either to fabrics prior to fabrication into garments, or as a garment durable press process imparting durable press properties to fabricated garments.
摘要:
A water-dispersible, antimicrobial and deodorant-finished product for fabrics comprising fine particles of an antimicrobial Schiff base derivative of an aminoglycoside as the active ingredient and a polyoxy-ethylenepolyalkylsiloxane for improving the resistance to washing.By using the antimicrobial and deodorant-finished product of the present invention, antimicrobial and deodorant fabrics having higher safety, more excellent antimicrobial and deodorant effects and longer duration of the effects than those of the conventional products can be obtained.
摘要:
Crushed foam-backed fabrics possessing improved dry cleaning resistance and cold crack resistance are provided using aqueous emulsion copolymers of ethylene and vinyl acetate containing from 3-9% of cross-linking monomers and having a molecular weight of at least about 300,000.
摘要:
Press-free garments are produced by treating a fabric with a mixture of (A) an aldehyde donor compound comprising an aminealdehyde compound and (B) a synergistic catalyst comprising (1) an acid salt of a primary aliphatic amine and (2) a quaternary ammonium salt of the formula: R-Y-CH2-NR1R2R3 X wherein R is an aliphatic hydrocarbon chain of 12 to 18 carbon atoms, Y is -CONH- or -O-, R1, R2 and R3 are alkyl groups or with the nitrogen atom form a substituted or unsubstituted heterocyclic ring and X is a halogen atom or mineral acid radical; or an alkylaryl N-alkyl sulfonamide. The treated fabric is then partially dried, cut, sewn, pressed and/or creased to form the garment and then cured at an elevated temperature; or dried, cured and then cut and sewn into the garment.
摘要:
The present invention provides a method of increasing the sun protection factor (SPF) rating of a fiber or fabric, comprising the steps of providing a UVR absorber, applying the UVR absorber to a fabric, whereby the UVR absorber is attached to the fiber and an application of less than 3% UVR absorber on weight of fiber produces an SPF rating of greater than 20 for the UVR absorber and fabric combination.
