Description
Technical Field
The invention relates to the technical field of textile printing and dyeing, and discloses a flexible anhydrous printing and dyeing method for thick polyester textiles.
Background
The textile industry is the traditional strut industry in China and comprises five parts of textile, printing and dyeing, chemical fiber, clothing, manufacturing of special textile equipment and the like. With the rapid development of national economy, the printing and dyeing industry in China also enters a high-speed development period, equipment and technical levels are obviously improved, and production processes and equipment are continuously updated. The printing and dyeing process refers to a general name of physical and chemical treatment of various textile materials (yarns and fabrics) in the production process, and comprises the processes of pretreatment, dyeing, printing and after-finishing of the textile materials, and the processes are collectively called as the printing and dyeing process. Dyeing is a process in which a dye is chemically or physicochemically bonded to a fiber, or a pigment is chemically formed on the fiber, so that the entire textile has a certain firm color.
With the development of textile industry, people have higher and higher requirements on textile fabrics, and fibrilia, cotton fiber and synthetic fiber are continuously developed. And the requirements on the color, moisture absorption, air permeability and ultraviolet resistance of the textile fabric are higher and higher. Therefore, textile printing and dyeing are rapidly developed, and the dyed textile has continuously abundant colors along with the continuous improvement and development of dyeing technology.
In order to achieve good color, color fixation firmness and environment-friendly fabric, the existing printing and dyeing technology is complex in process, and a large amount of color fixation printing and dyeing auxiliaries are adopted and continuously cleaned, so that dye waste is caused, and a large amount of sewage is generated. The printing and dyeing wastewater becomes a major development obstacle in the textile printing and dyeing industry. Waterless printing and dyeing gradually become the direction for developing environmental-friendly printing and dyeing in the future. At present, novel energy-saving and emission-reducing printing and dyeing technologies are developed, such as plasma printing and dyeing, laser printing and dyeing, supercritical carbon dioxide dyeing technology and vapor deposition dyeing technology, and anhydrous dyeing is realized. However, the existing anhydrous dyeing technology has higher requirements on process conditions, and has the defects of high energy consumption and poor stable control effect. If the supercritical fluid anhydrous dyeing technology has higher requirements on equipment, the supercritical carbon dioxide dyeing is still in a laboratory stage at present, and the large-scale application has more problems. The microwave dyeing technology is characterized in that water-containing fabrics generate heat after being irradiated by microwaves, and some dyes are subjected to induced temperature rise under the action of the microwaves, so that the aims of quick dyeing and color fixing are fulfilled, but the equipment cost is high, the speed is low, and the dyeing uniformity is influenced.
The Chinese patent application No. 201811291957.0 discloses a pure cotton velvet anhydrous printing and dyeing process, which comprises the steps of printing and dyeing, desizing, scouring and bleaching; the printing and dyeing steps comprise: (1) adding 0.1-0.5 weight part of hydrophilic softening agent and 5-8 weight parts of pure cotton linter fluorescent whitening agent into water at 60 ℃ so as to be used for washing the pure cotton linter for pretreatment; (2) and (3) putting an organic solvent instead of water into a dye vat, adding 1-4 parts by weight of disperse dye and 0.1-0.3 part by weight of uniformly dispersed dye, and running for 6 min.
The Chinese patent application No. 201710658735.7 discloses a printing and dyeing process of a printing and dyeing agent for polyester-acrylic-cotton blended fabric, which comprises the following steps: (1) adding 0.1-0.5 part by weight of hydrophilic softening agent and 7-9 parts by weight of polyester fluorescent brightener into water at 60 ℃ for pretreating polyester-acrylic-cotton blended fabric; (2) adding 2-4 parts by weight of disperse dye and 0.1-0.5 part by weight of disperse leveling agent, and running for 5 min; (3) adding 1-2 parts by weight of cation blue SD-BL and 0.1-0.3 part by weight of precipitation inhibitor, and running for 5 min; (4) adding 0.1-0.5 part by weight of acid leveling agent and 0.8-1.2 part by weight of acid dye, and running for 5 min; (5) adding 0.1-0.3 part by weight of glacial acetic acid, adjusting the pH value to 5-6, and finally adding 40-60 parts by weight of water to prepare the printing and dyeing agent; (6) dyeing; (7) and (5) refining.
