Technical field

The present invention relates to hyper-dispersants and Gemini surface active agent as dispersing aid, reaches disperse dyes granule and receives Grain of rice diameter Distribution Level can save so that it be made to have high-penetration rate and the high rate of transform under thermal transfer high-temperature and high-pressure conditions The purpose of about material improves the rate of transform, increases tinting strength, tinting power, reduce waste.It is transferred object and is generally chemical fibre class textile substrate, can replace Parts of traditional chemical fibre dyeing and printing process, reduces the discharge of its contaminant water.

Background technique

China is weaving big country, and the mainstream technology in present market is based on Conventional decal, and the processing step is many and diverse, prints simultaneously It needs a large amount of clear water to wash during dye, generates a large amount of waste water and gas.Because per pass technique requires distinct device, process route is multiple Miscellaneous, the printing and dyeing period is long, it is difficult to meet the flexible and changeable demand of current terminal market.Therefore National Development and Reform Committee is in analysis Chinese Seal After the status and development trend that contaminate industry, " traditional industries are transformed with information-based and new and high technology " is clearly proposed." informationization " That is " biometrics " controls production process by computer, this is the policy guidance of dyeing development.

Thermal dye sublimation transfer printing is current newest printing technology both at home and abroad, the technology be it is pre- first pass through the figure that needs are printed or On color print to film (paper), then by heating pattern transfer will be made directly on cloth, which has of low pollution, efficiently fast Victory, it is with short production cycle the features such as.In thermal transfer market segment, digital ink-jet thermal transfer is wherein more high-end printing and dyeing work again Skill, the technique can accomplish zero-emission, and efficiently quickly, equipment energy consumption is few, can be printed and dyed in real time according to the demand of client, full Sufficient market individual needs.Digital heat sublimation turns new and developing branch of the technology as hot industry of changing one's profession, and is in the high speed development stage in recent years, Future has the tendency that gradually replacing traditional thermal dye sublimation transfer printing paper industry.

Digital thermal Sublimation Transfer Printing Technology key point is digital ink-jet printed ink, which has conventional digital jetted ink There are also thermal dye sublimation transfer printing performances for feature.This special ink of development and production can be related to the preparation and function of disperse dyes nano color paste Auxiliary agent application (such as the modification of nano-material surface performance, material screening, nanoscale grinding technics, material compounds, between material Compatible performance etc.), especially disperse dyes particle must reach Nano grade, and general D95 reaches 50-200 nanometers of distribution models It encloses, and terminal ink stationary phase is in 1-2.

Summary of the invention

The technical problem to be solved by the present invention is to pass through the use of features auxiliary agent, reduce the abrasive grains of disperse dyes Diameter simultaneously improves thermal transfer efficiency, reduces the residual quantity in transfer.Disperse dyes are the ink composition of colorant very More patents are disclosed, such as the basic composition of United States Patent (USP) 7237886 open heat sublimation inks, water contain polyhydroxy The performance for the ink-jet ink that sugar alcohol, dyestuff, dispersing agent etc., but the patent do not refer to.Chinese patent CN101245204A is announced A kind of solvent-based inkjet ink, major technique are to complete the particle size dispersion to ink under high pressure by homogenizer, are made Partial size is distributed ink in 100-300 nanometer particle size, filters some to uniform and stable ink.It is invented different from this, the present invention is By the use of special addition agent, it can use particle diameter distribution within the scope of 50-200nm using traditional sand mill, simplify production Technique improves the stability that can also improve product simultaneously.United States Patent (USP) US2006/0272543A1 is mentioned to through sand mill just Within the scope of (D50) 20-130nm that pigment particles can be ground, the present invention is based on optimization dispersing aid formulas, by way of sand milling Disperse dyes are reached 50-200 nanometer size range, to improve the penetrating power of its later period thermal transfer, improve its rate of transform.

Preparation method program of the present invention includes following several parts

(1) pre-dispersed

The component of corresponding weight percent is mixed first, water, disperse dyes, auxiliary agent etc., first low speed is in dispersion machine On carry out dispersion 1-3 hour, slurries present uniform state stop stir.
