Description
Technical Field
The invention relates to a preparation method of high-temperature direct injection dispersion ink.
Background
China is a traditional printing and dyeing big country, and as a traditional printing mode, annual printing and dyeing wastewater discharge is one of important sources of water pollution in China, and extensive economy of changing resources into economy seriously hinders sustainable development in China.
At present, the thermal transfer digital printing technology widely used in the market mainly has the following defects: (1) a large amount of special paper for thermal transfer printing is consumed for thermal transfer printing, and a large amount of water resources are consumed for the paper making process and the recycling of waste paper, so that secondary pollution is caused, and a severe challenge is provided for green production and environmental protection in China; (2) the thermal transfer printing adopts the disperse dye with medium and low temperature, so that a finished product of the thermal transfer printing has a certain ink blurring phenomenon in the long-term storage process; (3) in the long-distance transportation of the thermal transfer printing, certain mutual color bleeding phenomenon can occur due to long-term high environmental room temperature, and the cloth or the ready-made clothes are easy to be stained, so that the cloth or the ready-made clothes become defective products, and have poor heat resistance stability and sublimation resistance fastness.
The high-temperature direct injection digital printing technology corresponding to the thermal transfer printing technology has the following advantages: (1) the water consumption is less: in the whole printing process, water is hardly needed, and only a trace amount of water is needed for sizing; (2) in the digital printing process and the high-temperature color fixation, water, color mixing paste and printing and dyeing waste liquid are not needed, so that the difficulties of high energy consumption, high pollution, high discharge and low benefit of the traditional printing are really and thoroughly eliminated; (3) paper is not needed in high-temperature digital printing, and secondary pollution is avoided; (4) the heat sublimation fastness, the rubbing fastness and the heat fastness of the printed finished product are greatly improved; (5) the printed product has stable quality and durability.
The star 1024 nozzle is an industrial-grade nozzle which is produced by specra and adopts a stainless steel structure and has an ultra-long service life, printing ink has certain corrosivity, the steel structure of the specra nozzle greatly improves the corrosion resistance of the nozzle to the printing ink, the nozzle has 1024 spray holes which are 4 times of that of a common nozzle, and the star 1024 nozzle is suitable for quick output and wide in applicability and is widely applied to variable data jet printing industries of industries such as advertisement, textile, ceramic tile and printing.
Traditional stamp pollutes greatly, the energy consumption is high, area is big, artifical the consumption is many, and digital printing replaces traditional stamp with its more green's stamp mode and becomes must trend, and thermal transfer printing digital printing also has very big defect simultaneously, and transfer printing's paper production pollutes greatly, and the stamp colour fastness is poor, and new industrial grade digital direct injection printing technology will certainly replace gradually. In a digital printing machine requiring high speed and high efficiency, a starlight 1024 nozzle is widely used, and the market also urgently needs ink suitable for an industrial-grade digital textile printing machine, particularly ink used for a novel digital printing machine with the starlight 1024 nozzle. However, no high-temperature direct-injection dispersing ink for a digital printing machine with a star 1024 nozzle exists in the domestic market at present, and although the high-temperature direct-injection dispersing ink exists in the foreign market, the coating technology is adopted, so that the preparation requirement of the auxiliary agent is extremely high, the preparation process is relatively complex, and the cost is high. At present, high-temperature direct-injection dispersion ink with low cost and simple preparation process is urgently needed in the market.
