Description

A kind of slurry for digit printing and its preparation method and application
Technical field
The invention belongs to digit printing field, and in particular to a kind of silk and cotton digit printing slurry and its prepare and Using.
Background technology
It is digital ink-jet printed as a kind of brand-new stamp mode, rapidly developed in recent years, represented following spinning The development trend in fabric stamp field.But the industrialization of digit printing is formed not yet, reason has a lot, such as plant issue, The price and quality problems of ink, technology problem etc., wherein pre-treating technology technical problem just account for greatly former Cause.Compared with Conventional decal mill base, in digit printing slurry, directly do not add dyestuff, but in one layer of fabric face uniform fold Thickener.The uniformity of this layer of thickener face, armful aqueous, hygroscopicity, wetability, permeability, washing performance, the transfer performance to dyestuff Etc. directly affect the color development uniformity of fabric, flower pattern fineness, a series of quality such as the rich and gaudy degree of color, osmotic effect, feel refer to Mark.Pretreatment fluid adopts traditional reactive printing gum, such as sodium alginate thickener etc. under normal circumstances, but easily occurs following Railway Project：The rich and gaudy degree for obtaining color is inadequate；Flower pattern fineness is inadequate；Permeability is inadequate.If on the basis of reactive printing gum The conventional reactive dye thickener of upper blending, this kind of thickener is nearly all high solids, thus while in tinctorial yield and Increase in fineness, but feel and permeability can become worse.The Chinese patent Shen of Publication No. CN103993489A A kind of cotton digit printing spinning sizing agent please be disclose, the cotton digit printing spinning sizing agent includes：80～88 parts of water, 1～3 part Sodium alginate, 3～5 parts of sodium bicarbonate, 5～9 parts of urea and 2～4 parts of glauber salt.Carried out using the cotton digit printing spinning sizing agent During digital printing, color fastness is preferable, but the rich and gaudy degree and flower pattern fineness that obtain color are not good enough.
The content of the invention
The invention provides a kind of silk and cotton digit printing slurry and its preparing and applying, the slurry is applied to silk During the digit printing of silk fabric and cotton, with preferably rich and gaudy degree and flower pattern fineness.A kind of slurry for digit printing, with weight The slurry, in the present invention, by the modified starch and reserve salt that add certain consumption in the slurry, is then used by amount percentages In silk and cotton is processed, digit printing is being carried out, the product for obtaining is while color fastness is ensured, while having preferably dense Gorgeous degree and flower pattern fineness.
In the present invention, the property of modified starch can produce crucial impact to the performance of slurry, so as to further have influence on The effect of digital printing.Preferably, the preparation method of described modified starch is as follows：
With inorganic base by the pH value regulated value 8～10 of starch milk, the alcohol of octenyl succinic acid anhydride is then added dropwise at 20～50 DEG C Solution is reacted, and keeps pH value between 8～10 in course of reaction, processes and obtain described modified after reaction completely after Jing Starch.When the modified starch obtained using the method is used to prepare slurry, product can be controlled with higher rich and gaudy degree and flower Type fineness.
Preferably, described post processing includes：The pH value of reactant liquor is adjusted to 6.5 or so, then Jing is filtered, washed Wash, be dried to obtain described modified starch.
Preferably, described inorganic base is NaOH or sodium carbonate.
Preferably, the solvent of the alcoholic solution of described octenyl succinic acid anhydride is ethanol, the matter of octenyl succinic acid anhydride Amount percent concentration is 10～20%.
Present invention also offers a kind of preparation method of the described slurry for digit printing, it is characterised in that include Following steps：
(1) sodium alginate is added water after stirring into paste, adds sodium acid carbonate, after stirring and dissolving, add modified starch, stirring is equal It is even to paste into former；
(2) under agitation, carbonyl diamide and reserve salt are slowly added in the former paste for obtaining to step (1), after being sufficiently stirred for Standing obtains described silk and cotton digit printing slurry.
Preferably, in step (2), whipping temp is room temperature, and mixing time is 30～60 minutes.
Present invention also offers a kind of application of the described slurry for digit printing, described slurry is used to locate filament carding Silk fabric or cotton.
Preferably, the application includes following operation：Textile sizing → drying → spray printing → decatize → cold water washes → hot water Wash → soap → hot water wash → cold water washes → dries.
Preferably, during starching, by the way of pressure folder on fabric slurry described in uniformly penetrating.
Present invention also offers a kind of printed fabrics, carry out process to fabric using described slurry and obtain；
Preferably, described fabric is silk or cotton.The printed fabrics had both had and had preferably not only had higher color jail Degree, and it is bright-colored, and compared with the existing technology, beneficial effects of the present invention are embodied in：
(1) by adding special modified starch, the modified starch is lenticular, therefore preparation color paste viscosity is little, has good Flow leveling and impregnability, and do not affect coloured light.After spray printing, fabric is clear-cut, and level solid is true to nature, bright in luster, makes Spray printing product quality it is overall be improved significantly, solve what Jing in jet printing process often occurred the rich and gaudy degree of color and fineness phase lance The problems such as easily there is feel at the problem and black of shield and harden.
(2) in technique is evaporated, the rich and gaudy degree of color development of the fabric that traditional pre-treating technology is processed in cylinder steamer is remote More than continuous steaming machine, but due to device structure problem, side aberration in the easy appearance of wide door paper web；Using continuous steaming machine just Side aberration in not existing, but it is poor to obtain the rich and gaudy degree of color.The color development that fabric is effectively improved using the slurry of the present invention is rich and gaudy Degree, can evaporate technique to determine according to the actual conditions of fabric door width, can be very good to take into account spray printing fabric color is rich and gaudy Degree and the color development uniformity, are that production solves practical challenges, make the quality more last layer of spray printing product.
