Embodiment 1

[0030] A low-cost anhydrous method for cleaning environmentally friendly printing and dyeing textiles, comprising the following steps:

[0031](1) Preparation of microcapsule dye: Dissolve hot-melt polymer polypropylene resin capsule wall material in ethyl acetate, the mass ratio of hot-melt polymer capsule wall material and ethyl acetate is 1:1, add The total mass of 5% gelatin was ultrasonically dispersed for 20 minutes to obtain an oil phase; the dye was dissolved in water, the mass ratio of the dye to water was 1:1, and 5% of the total mass of emulsifier nonylphenol polyoxyethylene ether was added to it, Ultrasonic dispersion for 20 minutes to obtain the water phase; slowly add the water phase to the oil phase, and stir in a high-speed shear emulsifier at a stirring speed of 3500rpm for 3 minutes, so that the hot-melt polymer capsule wall material covers the dye and obtains a stable The microcapsule dye is then continuously stirred at a stirring rate of 700rpm for 2h, unti...

Embodiment 2

[0036] A low-cost anhydrous method for cleaning environmentally friendly printing and dyeing textiles, comprising the following steps:

[0037] (1) Preparation of microcapsule dyes: Dissolve hot-melt polymer polypropylene resin capsule wall material in cyclohexane solvent, the mass ratio of hot-melt polymer capsule wall material and cyclohexane solvent is 1:1.5, to Add 5% gelatin of the total mass, ultrasonically disperse for 25 minutes to obtain the oil phase; dissolve the dye in water, the mass ratio of dye and water is 1:2, add 5% of the total mass of emulsifier fatty alcohol polyoxyethylene ether to it , ultrasonically dispersed for 25 minutes to obtain the water phase; slowly drop the water phase into the oil phase, and stir for 4 minutes at a stirring speed of 3600 rpm in a high-speed shear emulsifier, so that the hot-melt polymer capsule wall material covers the dye, and the obtained Stable microcapsule dyes, then continue to stir at a stirring rate of 800rpm for 2.5h, ...

Embodiment 3

[0042] A low-cost anhydrous method for cleaning environmentally friendly printing and dyeing textiles, comprising the following steps:

[0043] (1) Preparation of microcapsule dye: dissolve the hot-melt polymer polypropylene resin capsule wall material in a mixed solvent of ethyl acetate and cyclohexane, and the mass ratio of the hot-melt polymer capsule wall material to the mixed solvent is 1 : 2, add 5% gelatin of the total mass to it, ultrasonically disperse for 30 minutes, and obtain the oil phase; dissolve the dye in water, the mass ratio of the dye to water is 1:3, add 5% of the total mass of the emulsifier alkyl Phenol polyoxyethylene ether was ultrasonically dispersed for 30 minutes to obtain a water phase; the water phase was slowly added dropwise to the oil phase, and stirred for 5 minutes at a stirring speed of 3700 rpm in a high-speed shear emulsifier, so that the hot-melt polymer capsule wall material Cover the dye to obtain a stable microcapsule dye, then continu...

Abstract

The invention provides a low-cost waterless cleaning method for environmentally-friendly printing and dyeing textiles, and relates to the technical field of textile printing and dyeing. The low-cost waterless cleaning method comprises the following steps: microcapsule dye preparation, textile pretreatment, electrostatic spraying and hot-pressing trimming. By adopting the printing and dyeing methodprovided by the invention, no waste water is generated, the purposes of saving water and energy and reducing environmentally pollution are achieved, the dye is firmly combined with the textiles, excellent color fastness is obtained, and the microcapsule dye is of protectiveness for the textiles by adopting original silk liquid pretreatment and electrostatic spraying, so that light fastness, washing fastness, rubbing fastness and ironing fastness of the dyed textiles are obviously promoted; the preparation process is simple and easily controlled in technology, and is applicable for continuousmass dyeing of the textiles of various raw materials.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing, in particular to a method for low-cost anhydrous cleaning and environmental protection printing and dyeing of textiles. Background technique [0002] The printing and dyeing industry is an important part of my country's textile industry chain, and a key industry that drives spinning and weaving, and improves the grade and added value of clothing and home textiles. Textile printing and dyeing refers to the production process of dyeing and printing finished cloth through desizing, scouring, bleaching and other processes. After entering the 21st century. The contradictions of large resource consumption and high pollutant discharge brought about by my country's textile industry in the production process are becoming increasingly apparent. Printing and dyeing wastewater is mainly composed of desizing wastewater, cooking wastewater, bleaching wastewater, mercerizing wastewater, dy...
