Description
Technical field:
The present invention relates to a kind of preparation method of paint-printing colour size, belong to technical field of textile printing.
Background technology:
Dispersible pigment color paste is the colouring component in paint-printing colour size, mixed with water by auxiliary agents such as pigment, dispersant, emulsifying agent, wetting agents, the thick paste liquid of the colour made through attrition process, generally speaking, pigment particle size is less, the tinctorial strength of print paste, gloss and covering power etc. are better, are conducive to the application performance improving print paste.For graining paste, not only require that its chromatogram is complete, bright in colour, tinting strength, tinting power is high, fine size and evenly, and require that it not easily precipitates, there is stable chemical property and good fastness.Pigment itself does not have affinity to fiber, mechanically must anchor at fiber surface, thus complete stamp process by the film-forming of adhesive.Therefore, the index such as vividness, feel, fastness of PRINTED FABRIC, depends on the quality of adhesive to a great extent.
Pigment printing binding agent is generally divided into three major types, solvent type adhesive, water-dispersion type adhesive and Emulsion Adhesive.Front two classes are obtained by polymerisation in solution, and the 3rd class is then obtained by emulsion polymerisation.Emulsion Adhesive molecular weight is high, and emulsion particle diameter, generally at 0.05-0.2 μm, is adhesive the most frequently used at present.
The stability of pigment dispersion system is relevant with many factors, relates to the characteristic of decentralized medium, particle surface polarity and by media wet degree and distribution etc.For making dispersion have more satisfactory stability, mainly realize by following approach:
L () adds the surfactant of debita spissitudo and suitable ionic type, and make their selective absorptions on the surface of pigment particles;
(2) with high molecular surfactant, surface treatment is carried out to pigment, and be adsorbed on particle surface, according to steric hindrance effect, dispersion is tended towards stability;
(3) viscosity of decentralized medium is increased to control Brownian movement and the natural gravity sedimentation thereof of pigment particles;
(4) density contrast between pigment particles and decentralized medium is reduced;
(5) the zeta current potential of pigment particles is reduced.
Current COAT PRINTING also exists many disadvantages, and the fastness such as friction, washing of COAT PRINTING that especially outstanding is is lower, and do not reach high-quality requirement far away, fastness problem seriously constrains further developing of COAT PRINTING industry.Therefore, in the global piece market that current competitive is growing more intense, want the demand in adaptation market, integrate with the world market, fastness problem is the primary realistic problem that China colourist faces.
Chinese invention patent CN201210516593.8 discloses a kind of method preparing weaving use UV paint-printing colour size, adopt outer emulsion process and ultrasonic assistant legal system for the polyurethane-acrylate emulsion going out oil-in-water type, adopt sand mill polishing to add aqueous dispersion and prepare water paint mill base, again mill base is joined in polyurethane-acrylate emulsion, and add initator, thickener, prepare the waterborne UV coating mill base that can be used for textiles, prepared waterborne UV coating print paste has energy-conservation, environmental protection, the feature that technological process is short, of the present invention closest to prior art, but this inventive method does not well solve for the problem that fabric color fastness is lower.

The pigment degree of depth refers to that the color of opaque solid matter gives the depth preception directly perceived of people or the concentration of color, its size often by coloring matter content in solid matter number, the various factors such as the physical state of coloring matter, the optical property of the surface of solids impact, the size of color depth value represents by K/S value usually, K/S value is larger, represents that color is darker; K/S value is less, then represent that color is more shallow.
Method of testing adopts Datacolor650 type color measurement and color match instrument to measure the K/S value of dyeing sample, and each sample is got five difference colour examinings and asked its mean value.
2. the test of washing fastness
With reference to GB/T3921.1-1997 standard, color fastness to washing test instrument measures the staining of dyeing sample and fastness of fading respectively.Adopt Datacolor65O type color measurement and color match instrument, measure calico staining aberration and former cloth and to fade aberration, by its fastness rank of AATCC/ISO standard rating.
3. the test of dry wet colour fastness to rubbing
Dry fastness to wet rubbing test is with reference to GB/T3920-1997 standard.Sample is 50mm × 200mm, and each two pieces through broadwise, standard friction cotton is 50mm × 5Omm.
4. hand feel performance test
Close order and touch the fabric after arranging, with 5-10 people for a small group, grade, according to different feels, PRINTED FABRIC is carried out hand feel evaluation, concrete assessment method is: carry out feel grading from flexibility, smooth feeling two aspect, be divided into 5 grades, 1 grade the poorest, and fabric feeling is comparatively hard, and sliding glutinous sense is poor, 5 grades best, and fabrics feel soft, cunning are glutinous.
Concrete grading as shown in Table 1.
Table one: feel is graded
| 5 grades | 4 grades | 3 grades | 2 grades | 2 grades |
| Very good | Well | In | Slightly poor | Difference |
Table two: the embodiment of the present invention is to the printing quality of pure cotton fabric
The print paste process that method described in the embodiment of the present invention prepares is on pure cotton fabric textiles, and the textile textiles obtained has good COLOR FASTNESS and hand feeling quality, and K/S value is comparatively large, and Color is good.
Experiment one: preliminary drying temperature is for the impact of the printing quality of pure cotton fabric:
Experimental technique: the preparation method adopting the paint-printing colour size described in embodiment eight, by paint-printing colour size process on pure cotton fabric textiles, inquires into the impact of preliminary drying temperature for the impact of printing quality.
Table three: paint-printing colour size preliminary drying treatment temperature is to the printing quality of pure cotton fabric
It is 50 DEG C that the present invention is used in preliminary drying temperature, and lower than 50 DEG C, its printing quality improves along with the rising of preliminary drying temperature, and higher than 50 DEG C, its printing quality then reduces along with the rising of temperature, and at 50 DEG C of temperature, its printing quality is optimum.
Experiment two: fixation UV intensity is for the impact of the printing quality of pure cotton fabric:
Experimental technique: the preparation method adopting the paint-printing colour size described in embodiment eight, by paint-printing colour size process on pure cotton fabric textiles, inquires into the impact of UV intensity for printing quality.
Table four: fixation UV intensity is for the impact of the printing quality of pure cotton fabric
Along with the increase of fixation treatment process medium ultraviolet intensity, its hand feeling quality reduces gradually, K/S value rises gradually, and its fastness to rubbing presents the trend first rising and reduce afterwards, so adopt UV intensity to be 150-180W/cm in process of the present invention along with the rising of UV intensity.
Above content is only better embodiment of the present invention, and for those of ordinary skill in the art, according to thought of the present invention, all will change in specific embodiments and applications, this description should not be construed as limitation of the present invention.
