Embodiment 1
[0009] The woven cashmere fabric is pretreated with a compound surfactant, dried, printed with digital inkjet, and steamed for a short time.
[0010] The compound surfactant formula is: non-ionic surfactant polyethylene glycol monolaurate or fatty alcohol and ethylene oxide condensate or fatty acid amide condensate, the mass percentage of which is 5-95%; cationic surfactant Cetyl trimethyl ammonium bromide or alkyl dimethyl benzyl ammonium chloride, the mass percentage is 95-5%.
[0011] The technical formula of the pretreatment liquid is (by weight percentage): 0.01% to 5% of the above-mentioned compound surfactant, 2% to 8% of urea, 2% to 8% of acid agent, 0.5% to 5% of printing paste, The rest is water.
[0012] The pretreatment method adopts one dipping and one rolling (or multiple dipping and multiple rolling), and the excess rolling rate is controlled at 120%.
[0013] Drying after pretreatment, followed by digital inkjet printing with reactive dyes. After printing, t...

Abstract
The invention relates to a digital ink-jet printing short-time steaming dye-fixation method for a cashmere fabric. The method is characterized in that a nonionic and cationic compound surfactant is applied in pretreatment of the cashmere fabric. The compound surfactant has an infiltrating and swelling effect on cashmere scales and scale intercellular substances and cooperates with a dye, so that an ink-jet printing dye is quickly applied, and short-time steaming is achieved. The compound surfactant comprises, by mass percentage, 5-95% of polyethylene glycol monolaurate or a condensation substance of fatty alcohol and ethylene oxide or an aliphatic acid amide condensation substance, and 95-5% of cetyl trimethyl ammonium bromide or alkyl dimethyl benzyl ammonium chloride. The pretreatment isapplied through padding or scraping printing, and then drying and ink-jet printing are carried out. The steaming dye-fixation condition of ink-jet printing is carried out in a condition that the temperature is in a range of from 102 to 108 DEG C, and the steaming time is no more than 40 min. The color depth of conventional digital ink-jet printing of a cashmere fabric is achieved.
Description
technical field [0001] The invention relates to the technical field of short-time steaming color-fixing of cashmere fabric digital ink-jet printing. Background technique [0002] The existence of the scale layer on the cashmere fiber surface will hinder the dyeing of the dye, and the inkjet printing of the cashmere fabric usually takes a long time to fix the color. Usually, the cashmere printing needs to be steamed for at least 60 minutes, so a lot of energy is consumed, and it will also Damage cashmere and affect product quality. [0003] In order to improve the performance of dyeing cashmere with dyes, cashmere is usually modified. The modification of cashmere fiber is generally divided into chemical, physical or biological means. Chemical treatment often uses oxidation methods to treat cashmere scales, such as hydrogen peroxide treatment, which uses the oxidation of hydrogen peroxide to break the disulfide bonds of wool scales, passivate and loosen the scales, so that d...
