Description
Technical Field
The invention relates to the technical field of textile, in particular to a fine printing method of a blanket.
Background
With the development of the times, the demands of people on fashion and individuation are continuously increased, but due to the properties of the blanket and materials thereof, in the fine printing process, the patterns are fine, the lines are thinner, and the light colors of the patterns are easily permeated and covered by dark ground colors, so that the patterns become fuzzy, and the overall effect of the patterns is affected. Therefore, the pattern of the blanket is single and not fine enough, and the requirements of people on the pattern are not met.
The cationic polyester yarn developed and produced in recent years meets the personalized and differentiated requirements of modern people and is popular with people. Different yarns can also exhibit differences in hand and quality. For example, a plain cationic polyester blanket is usually dyed with a cationic, plain polyester blend fabric to provide a blanket with a colored, colorless or multi-colored alternating effect. The principle is that different polyester raw materials are utilized to realize different dyeing performances of different dyes, so that the color effects are different, and the brightness difference or the color difference effect of the blanket surface color is realized. However, the method requires special textile and dyeing processes, and has high process requirements and high cost.
Disclosure of Invention
Aiming at the problems in the prior art, the invention provides a fine printing method of a blanket. The method mainly utilizes the characteristic that the dye is easy to hydrolyze under alkaline conditions due to the fact that the groups such as ester groups and amide groups are contained in disperse dye, so that the color paste is changed in color and lost in dyeing, and the light color paste and the dark color paste are specially selected and used, so that the method has a good control effect on color shifting and infiltration of flowers.
The technical scheme of the invention is as follows:
the fine printing method of the blanket comprises the steps of manuscript drawing, plate making, color paste preparation, printing, after-finishing and the like, wherein the color paste preparation step is used for preparing two types of color pastes: one is a flower-shaped base color paste, the other is a special color paste special for flower-shaped parts, and the other is an alkaline color paste.
Preferably, the alkaline color paste comprises the following components in percentage by mass: 4 to 6 percent of alkali-resistant composite paste, 0.3 to 0.8 percent of sodium carbonate, 0 to 1.8 percent of alkali-resistant disperse dye and the balance of water; the viscosity of the slurry is 1000 mPas to 1300 mPas; wherein, the alkali-resistant composite paste is compounded by sodium alginate and a dispersion thickener according to the mass ratio of 7:3.
Preferably, the alkali-resistant disperse dye is selected from orange ALD, red ALD, blue ALD, and the like, produced by Zhejiang Ji chemical groups.
Preferably, the flower-type ground color paste comprises the following components in percentage by mass: 2-3% of a disperse thickener, 0-1.5% of a non-alkali-resistant dye and the balance of water; the viscosity of the slurry is 1000-1300 mPa.s.
However, the amounts of alkali-resistant disperse dye and alkali-non-resistant dye cannot be 0% at the same time.
And proper slurry concentration is selected according to different fineness of patterns, so that the mutual infiltration degree of color paste is reduced.
The plate making comprises the steps of plate stretching, washing, coating photoresist, ink jet, exposure, development, painting and plate airing.
Preferably, in the plate stretching process, a 120-mesh net wire is adopted for net making, and the net making tension standard is 25-30n/cm.
Preferably, the photoresist is coated on both sides of the screen plate by a sizing device in the process of coating the photoresist, the strength is uniform, the thickness of the photoresist is uniform, the photoresist is required to be coated for the second time, the photoresist layer coated for the first time is required to be completely dried, or else the adhesive film is easy to fall off. The drying temperature is controlled at 40 ℃, so that the adhesive film is easy to crosslink and embrittle due to the overhigh temperature, difficult to develop and reduced in resolution.
Preferably, the ink-jet process prints the screen-making picture of the design room drawing on the screen coated with the photoresist by using a digital ink-jet printer, and the ink layer is required to completely and uniformly cover the pattern part and fully shield the light.
Preferably, development: fully wetting the two sides of the screen plate with normal-temperature clean water for 1-2 minutes, and uniformly flushing the plate surface (the exposed part of the screen plate loses water solubility and is flushed by water) by using a high-pressure water gun until all patterns are clearly developed; removing the water in the layout, and drying in an oven at 40 ℃. When the plate is punched, attention is paid to the pressure of the water gun and the distance between the screen plates, and the line edges are easily sawed due to overlarge pressure or overlarge distance, so that the net points are broken or lost.
Preferably, the paint: when the paint is painted, two people pull the paint scraping rod at a constant speed in the same direction to drive the paint to be coated on the screen plate, and the periphery of the screen plate is paved with reinforcing cloth strips, so that the cloth strips are stretched and flattened, no wrinkling is ensured, the paint is uniformly discharged from the cloth strips, and no gap is generated. And (3) immediately performing paint sucking operation after painting to remove redundant paint at the pattern position, developing and printing the pattern, wherein the paint sucking is performed by two people to uniformly pull the screen on the paint sucking machine, and the translation distance and the pulling times are determined according to the size of the screen so as to ensure the integrity of the pattern after paint sucking.
Preferably, the plate is dried: the screen plate after being painted and sucked is naturally dried (the special case can be dried by an oven) by being placed on a plate-making room plate-airing frame without dust and flower hair, and is protected, sundries cannot be fallen on the screen plate, and screen plate defects are caused. After the screen printing plate is dried, the screen printing plate is repaired for standby.
The after-finishing process flow mainly comprises the following steps: front brushing, back brushing, ironing and shearing and the like.
Preferably, single roller bristles are used in the post-treatment process to minimize pattern variation.
Other treatment processes can be carried out by adopting a conventional process of blanket treatment.
The printing process can realize finer printing effect, the fineness of the pattern lines can be accurate to 0.5mm, the printing process is particularly suitable for some special printing formats, such as the pattern effect of cation AB yarns, and the pattern effect can be realized by dividing dark colors and light colors in pictures into two plates to be respectively scratched in the process of drawing and color separation through repairing and separating. But in comparison, the method is simpler and easier to implement, and does not have the impression of felt hand feeling limited by process materials.
