The invention discloses a reactive dye dip-dyeing technology of cotton fabric, comprising the following steps: S1, pretreatment: carrying out scouring and bleaching treatment on cotton fabric, and successively carrying out enzyme washing and sizing; S2, dyeing: immersing cotton fabric into reactive dye liquor, dyeing at 20-30 DEG C, heating to 70-100 DEG C at the speed of 2-3 DEG C / min, adding 1-5 g / L of soda ash according to volume of the reactive dye liquor, carrying out thermal insulation at the fixing temperature of 40-100 DEG C for 5-25 min, adding 5-20 g / L of chitosan quaternary ammonium salt according to volume of the reactive dye liquor, carrying out thermal insulation for 30-60 min, and finally cooling to room temperature; and S3, aftertreatment: washing the cotton fabric, soaping, washing, and air-drying. The reactive dye dip-dyeing technology of cotton fabric has advantages of high fixation rate and good level-dyeing property. In addition, the technology is simple. By the technology, dye wastewater can be greatly reduced, and the environment is protected.

The invention relates to the technical field of disperse dyes and provides a monoazo compound as well as a preparation method and application thereof for the purposes of solving the problems that dyeing is carried out on fabrics such as terylene and superfine fiber so as to obtain very deep color and excellent washing resistance fastness and sublimation resistance fastness. The monoazo compound has a general formula (I). When the monoazo compound is dyed on fabrics such as terylene and superfine fiber, the obtained fabrics have very deep color, excellent washing resistance fastness and sublimation resistance fastness, friction resistance color fastness and light fastness and good color fixation rate in dip dyeing. The monoazo compound provided by the invention is also suitable for compounding of mixed tones with other disperse dyes.

The invention aims to provide a dyeing process of flame-retardant mixed fiber. The dyeing process includes following steps: adding the flame-retardant mixed fiber into a desizing water solution of 50-60 DEG C, holding the temperature, and washing with water at 50-70 DEG C; adding the flame-retardant mixed fiber that is desized into a rinsing water solution of 95-100 DEG C, holding the temperature, and washing with water at 50-70 DEG C; unhairing; adding the flame-retardant mixed fiber that is unhaired into water of 15-35 DEG C, rising the temperature to 100-102 DEG C, adding dye at 68-71 DEG C, adding a dye auxiliary at 95-100 DEG C, and holding the temperature at 100-102 DEG C; rising the temperature to 130-135 DEG C, and holding the temperature at 130-135 DEG C; lowering the temperature to 75-80 DEG C; taking out the flame-retardant mixed fiber, and soaping the flame-retardant mixed fiber at 75-80 DEG C; taking the flame-retardant mixed fiber dyed for the first time, padding the flame-retardant mixed fiber in dye liquid, and air-drying at high temperature; padding the flame-retardant mixed fiber in color fixing liquid, and performing saturated steaming at high temperature; subjecting the flame-retardant mixed fiber after saturated steaming to water washing at 10-15 DEG C, acetic acid neutralizing, soaping at 85-90 DEG C and water washing at 15-35 DEG C sequentially; taking the flame-retardant mixed fiber after being dyed, and subjecting the flame-retardant mixed fiber to air finishing and full decatizing sequentially. The dyeing process has the advantage that dyeing effect is improved.

The invention discloses a dyeing and finishing process for a pure coffee yarn spun fabric. The dyeing and finishing process comprises the following working procedures: a pretreated dyeing one-bath process procedure, a soaping procedure, a softening procedure, and a moisture absorption and sweat releasing finishing procedure, wherein the unique TCB pretreated dyeing one-bath process is adopted; after dyeing, the soaping and softening treatment is adopted; meanwhile, in the moisture absorption and sweat releasing finishing procedure, a finishing agent is selected and blended, and the special moisture absorption and sweat releasing finishing process is adopted, so that the better air permeability and the better rubbing fastness can be achieved.

The invention discloses a polyurethane self-skinned cushion water-based coating and a polyurethane self-skinned cushion. The invention provides a polyurethane self-skinned cushion water-based coating, which comprises the following components in parts by mass: 66-84 parts of water-based epoxy resin, 9-17 parts of hyperbranched polyethyleneimine, and water-based polyurethane prepolymer 5 to 20 copies. The water-based coating has good adhesion and flexibility, as well as color fastness to rubbing, resistance to reagents, low temperature resistance and high temperature resistance, and the preparation method of the water-based coating has the advantages of non-toxicity, no pollution and no residue, It has wide application prospects in the preparation of polyurethane self-skinned cushions; the present invention further provides a method for preparing polyurethane self-skinned cushions with water-based coatings, and the cushions prepared by the method have good wear resistance, antifouling, and Chemical, cleaning agent resistance, aging resistance, mass production and wide use.
