Description

Print paste preparation and printing technology thereof
Technical field
The present invention relates to a kind of print paste preparation and printing technology thereof, belong to dyeing or the printing technique field of textiles.
Background technology
In prior art, conventional stamp is mainly by screen printing and digit printing, screen printing mainly comprises ROTARY SCREAM PRINTING and PLATE SCREAM PRINTING, the speed of ROTARY SCREAM PRINTING and PLATE SCREAM PRINTING, but pattern brightness is lower, flower type resolution ratio is poor, and the fabric of printing hardens, feel is poor, and the dye environment adopting pollutes larger; Although digit printing has solved the problem of colored type resolution ratio and definition, stamp speed is slower, generally only has 10m 2/ h, and, being subject to the restriction of digital decorating machine, stamp fabric width is limited, and majority can only be printed on the fabrics such as polyester-cotton blend simultaneously, and textile class cannot realize stamp.
Have based on this, make the present invention.
Summary of the invention
The object of this invention is to provide the preparation method of a kind of pollution-free, low energy consumption, print paste that production efficiency is high, and adopt the printing technology of this print paste.
For realizing the object of the invention, the technical scheme of taking is as follows:
The preparation method of print paste: each raw material is carried out to fine finishining, then carry out mixture with printing paste, wherein the mass percent of pigment is 1-10%, and the mass percent of printing paste is 90-99%.
Further arranging of technical solution of the present invention is as follows:
Described raw material is mainly red (Shanghai Lao An coating Co., Ltd, model: No. 11), yellow (Shanghai Lao An coating Co., Ltd, model: No. 21), blue (Shanghai Lao An coating Co., Ltd, model: No. 31) and black (Shanghai Lao An coating Co., Ltd, model: No. 53) pigment, printing paste is space-based printing material factory of Shaoxin City, model: 118A.
Described fine finishining refers to grinds pigment, until pigment fineness≤300 order.
Described printing paste is mainly acrylic emulsion, auxiliary agent and thickener, by three's mix and blend, and speed of agitator 2000-3000r/min, processing time >=30 minute, filling.
The mass percent of described acrylic emulsion is 10-50%, and auxiliary agent is pure water, and mass percent is 1-10%, and surplus is thickener.
Described thickener is sodium alginate, acrylic acid, CMC(sodium carboxymethylcellulose) or starch.
The printing technology flow process of print paste prepared by employing technique scheme is: print paste preparation → stamp → oven dry, wherein, stamp comprises: slice → plate-making → drawing a design.
Described plate-making, for to apply aqueous sensitizing glue on silk screen or nickel screen, is then dried at 10-80 DEG C, then retouches sample film-making.
Described oven dry adopts nature to dry or steaming box is dried, and wherein, the temperature of steaming box is 50-150 DEG C.
After described oven dry, need to shape, setting temperature is 60-150 DEG C, and shaping time is 1-10 minute.
Adopt the beneficial effect of technical solution of the present invention as follows:
1. energy-saving and emission-reduction, printing paste environmental protection used, the stamp material of mixture is difficult for coupling, can deposit the long period;
The dry grinding COLOR FASTNESS of the fabric that 2. stamp obtains can reach 4 grades, and wet-milling COLOR FASTNESS can reach 3 grades;
3. stamp is bright in luster, and clear patterns degree is high, and cloth softness, applicable to various fabrics such as polyester-cotton blend, people cottons;
4. fabric width is not limit, and stamp speed is fast.
Adopt technical solution of the present invention both to overcome in screen printing the not bright-coloured and not high problem of figure clarity of pattern, overcome again simultaneously in digit printing, yield poorly, defect that fabric width is limited, stamp fabric width is improved, stamp speed, generally can reach 3000m/h, the pigment and the base-material that adopt are free of contamination green colouring material, environment are not polluted to energy-saving and emission-reduction.
Wherein red, yellow, blue, the mineral black after fine finishining is called magenta, product Huang, reddish blue, product are black.
