Abstract
The invention discloses a pretreatment liquid for direct injection of polyester fiber through dispersive ink and a direct injection digital printing process. The pretreatment liquid comprises, by mass, 0.2-5 parts of thickener, 1-10 parts of dispersion promoter, 2-5 parts of sodium chloride and 76-95 parts of water. The pretreatment liquid is semi-thick liquid, polyester fabric after going through impregnation or padding treatment liquid is dried, injection printing of dispersive dye ink is performed, high-temperature steaming baking is performed for color fixing after drying, water washing is performed, and then drying is performed to obtain a printing finished product. The pretreatment liquid is simple to prepare, convenient to use and suitable for direct injection process digital printing of all fabric high in polyester content, and the pretreatment liquid is easy to wash away after printing, so that hand feel of fabric is unaffected. Conventional heat transfer printing is replaced by the dispersive direct injection process, and transfer printing paper is not used, so that the direct injection digital printing process is environment-friendly. The pretreatment liquid can effectively prevent ink from spreading around on the polyester fabric, so that patters are ensured to be exquisite and lines are ensured to be clear after printing; color yield rate is high, printing is saturated and bright in color, and visual three-dimensional sense is high.
Description
Technical field
The present invention relates to digital printing technology field, more particularly, to a kind of pretreatment fluid of dispersible ink direct-injection terylene and straight
Spray digit printing technique.
Background technology
Ink-jet printed technology is a brand-new high accuracy printing technique, and color representation power is very strong.The fabric of fabric is to spray
The impact of ink-printed effect is very big, and terylene itself, due to being hydrophobic fibre, carries out digit printing using direct-injection technique and there is ink
Water very serious problem of imbibition on dacron, pastes slurry over using traditional stamp is former, anti-imbibition effect is poor, and unstable
Fixed, wear-resisting, light fastness is low, and ink effective rate of utilization is low.So at present digit printing is carried out on polyester fabric can only adopt
Printed pattern is first printed on heat-transferring printing paper thermal transfer mode, then turns again and scalds in fabric face.But, using thermal transfer
Technique carries out digit printing, and not only lines can be flattened impact because of hot pressing by the product of thermal transfer concave convex texture on jacquard fabric
Feel and visual experience, fabric is as hot pressing produces gloss, and caloric transfer printing technology is complicated, and process costs are high, but also
Expend heat-transferring printing paper.So a kind of direct-injection digit printing technique of dacron of offer is very necessary.
In order to meet the ink-jet printed requirement to fabric property of direct-injection, prevent ink from directly printing to and ooze on fabric
Change, suitable pretreatment must be carried out for ink-jet printed fabric, can be only achieved satisfied ink-jet printed effect.Using difference
Ink and different fabric, ink-jet printed pretreating process is not quite similar.Many ink manufacturers are all developing both at home and abroad
It is suitable for the pretreating agent of oneself ink performance, such as to the process of dacron using plasma, cationization or colloidal sol one
Gel method pads process, to improve anti-imbibition performance during polyester fabric dye ink jet stamp.But offshore company produces pre-
Inorganic agent high cost, expensive.At present using ink-jet printed, the domestic at present Ink Factory of disperse dye ink more than dacron
Family focuses mostly on paint ink to the research of the ink-jet printed pretreating process of dacron, and disperse dye ink is used for terylene
The ink-jet printed pretreating process research of fabric is less, and is directed to disperse dye ink direct-injection dacron and provides a kind of pretreatment
Liquid is highly desirable to.
Content of the invention
The technical problem to be solved is to provide a kind of pretreatment fluid of dispersible ink direct-injection terylene and direct-injection number
Code printing technology.
The technical solution used in the present invention is:
A kind of pretreatment fluid of dispersible ink direct-injection terylene, the thickening agent comprising 0.2-5 mass parts, the dispersion of 1-10 mass parts promote
The water of stain, the sodium chloride of 2-5 mass parts and 80-97 mass parts, described thickening agent includes polypropylene acids macromolecular material.
The pretreatment fluid of dispersible ink direct-injection terylene according to claim 1 it is characterised in that described thickening agent also
Including at least one in carboxymethyl cellulose, synthetic gum tragacanth or a slurry.
In some specific embodiments, enforcement polypropylene acids macromolecular material is sodium polyacrylate.
In some specific embodiments, described dispersion accelerant is sodium dihydrogen phosphate, in acetic acid or tartaric acid extremely
Few one kind.
Present invention also offers the direct-injection that a kind of pretreatment fluid using dispersible ink direct-injection terylene as above is carried out
Digit printing technique, comprises the following steps:
S1: prepare pretreatment fluid: weigh the water of 80-97 mass parts, more successively by the thickening agent of 0.2-5 mass parts, 1-10 mass
The dispersion accelerant of part, the sodium chloride of 2-5 mass parts are added to the water, and stirring and dissolving obtains pretreatment fluid；
S2: the pretreatment fluid using described s1 gained carries out pretreatment to dacron, dries, obtains pretreated terylene and knit
Thing；
S3: will be drawn a design by digit printing machine and described pretreated dacron is painted on dispersible ink
On, dry；
S4: high temperature steaming bakes.
In some specific embodiments, during the viscosity ＜ 500mpa s of described pretreatment fluid, in described s2, pass through leaching
Roll formula starching machine and pretreatment is carried out to dacron using pretreatment fluid.
In some specific embodiments, during the viscosity >=500mpa s of described pretreatment fluid, in described s2, pass through leaching
Roll any one in formula starching machine, cylinder printing machine or flat screen printing machine, pretreatment is carried out to dacron using pretreatment fluid.
In some specific embodiments, in preprocessing process in described s2, the band liquid measure of dacron is 60%-
100%.
In some specific embodiments, in described s2, drying temperature is 75-95 DEG C, and drying time is 1-3min.
In some specific embodiments, in described s3, drying temperature is 70-80 DEG C, and drying time is 1-2min.
In some specific embodiments, in described s4, baking temperature is 170-190 DEG C, and the time that bakes is 5-10min.
In some specific embodiments, after described s4, also include s5: washing, it is clear that described washing inclusion is carried out successively
Water cleaning, reduction washing, the step of clear water washing.
In such scheme further preferred embodiment, the used reduction cleaning liquid of described reduction washing comprises even
Sodium sulfite, sodium hydroxide and water.
The invention has the beneficial effects as follows:
The invention provides a kind of pretreatment fluid of dispersible ink direct-injection terylene and direct-injection digit printing technique, dispersible ink direct-injection
The pretreatment fluid of terylene, comprises the thickening agent of 0.2-5 mass parts, the dispersion accelerant of 1-10 mass parts, the chlorination of 2-5 mass parts
Sodium and the water of 80-97 mass parts, pretreatment fluid is half thick liquid, and its viscosity is 100～3000 mpa s, and dacron is through leaching
