Temperature-sensitive color-changing paint dyeing technology of textile fabrics

The invention discloses a temperature-sensitive color-changing paint dyeing technology of textile fabrics. The process flow is as follows: selection and composition of the temperature-sensitive color-changing paint; preparation of temperature-sensitive color-changing dye microcapsules; preparation and dyeing of a temperature-sensitive color-changing pigment printing paste, dehydration, and baking to obtain a temperature-sensitive color-changing fabric. The textile fabric is a fabric which is prepared by pretreatment of cotton, Tencel fiber, modal fiber, chemical fibre blended cotton (lanca, polyester cotton and nylon cotton), silk, wool and the like. Through combined actions of ambient temperature, temperature inside clothes and body temperature, the color of the temperature-sensitive color-changing textile obtained by the application of the dyeing technology changes when the surface temperature of the textile achieves or exceeds color-changing temperature; and when the temperature drops below the color-changing temperature, the textile turns to the original color. With the change of the temperature, the textile fabric shows unexpected color and pattern, and the pattern will change based on movement of the body. The color-changing fabric can be widely applied in T-shirt, trousers, swimsuit, casual gym suit, working clothes, children's clothing, curtain, toy and the like.

Core-shell type paint dyeing and printing adhesive agent emulsion and preparation method thereof

The invention discloses a method for preparing core-shell emulsion type adhesive which is modified by hydroxyl-terminated acrylic ester and is used in fabric printing and dyeing processes. The adhesive is prepared through the following steps: soft monomers copolymerize with crosslinking monomers and portions of hard monomers to produce core-shell particles; then a small portion of soft monomers and a large portion of crosslinking monomers copolymerize with hard monomers to coat the surface of the core layer, thus obtaining a shell layer and forming stable core-shell type emulsion. One or the mixture of two or more from 2-hydroxyethyl acrylate, hydroxypropyl acrylate, hydrobutyl acrylate and hydrohexyl acrylate is taken as a portion of soft monomers and crosslinking monomers; one or the mixture of two or more from hydroxylmethyl methacrylic acid, 2-hydroxyethyl acrylate methacrylic acid and hydroxypropyl methacrylic acid is taken as a portion of hard monomers and crosslinking monomers; one from butyl acrylate, ethyl acrylate and 2 ethylhexyl acrylate is taken as main soft monomers; one or the mixture of two or more from methyl methacrylate, crylic acid, cinnamene, acrylonitrile and methacrylic acid is taken as the hard monomers; surfactant sodium dodecyl sulfate, sodium dodecyl benzene sulfonate and octyl phenol polyethylene glycol are taken as emulsifying agent; potassium persulfate or ammonium persulfate is taken as initiator; and the copolymer emulsion is produced through emulsion copolymerization. Observed by transmission electron microscopy, the particles of the emulsion have visible core-shell structure and are even in distribution; the emulsion is stable, absolutely has no formaldehyde release both during the machining and using processes; the emulsion can be used both for pigment printing and for pigment dyeing.

The invention discloses a preparation method and use of a ketone hydrazine crosslinkable acrylic ester and polyurethane composite textile emulsion. Cobalt 60 - gamma radiation method polymerization process is used for overcoming low color fastness and high aldehyde content of the bond of resinfixed pigment printing. Acrylic ester emulsion incorporating active ketone carbonyl is synthesized by acrylic ester mixxed with monomer and diacetone acrylamide(DAAM). The ketone hydrazine crosslinkable acrylic ester and polyurethane (PUA) composite textile emulsion is prepared by mixxing the acrylic ester emulsion with polyurethane emulsion incorporating diazanyl in definite proportions. Infra-red spectrum(IR), mechanical property and hydrolytic resistance deo tecting methods are used to analyze the composite textile emulsion and to detect the color fastness and environmental protection of the bond of resinfixed pigment printing. The result indicates when the content of DMMA is between 1.3 and 1.4 percent, the performance of the PUA composite textile emulsion is good and the bond based on the emulsion is an environmentally friendly product which is aldehydeless and without APEO, the aldehyde content satisfy infant clothing, and colour fastnes to brush-washing and crocking fastness are improved.
