Problems solved by technology

However, for plush blankets and blankets with a higher grammage, such as high-pile Raschel blankets, when the above-mentioned three sizing pre-treatment methods are used to pre-treat high-pile Raschel blankets, the fluff will be overwhelmed. Once the fluff is overwhelmed, That is, one piece of fluff is pressed on top of another fluff, layer by layer. In this case, when printing ink, during the pressure seepage process, the slurry will flow from the head of one fluff to the head of another fluff with the ink, and the penetration effect will be greater. very bad

Embodiment 1

[0056] see Figure 1 to Figure 6 .

[0057] The present embodiment 1 discloses a kind of Raschel blanket digital inkjet printing method, and its steps are as follows:

[0058] Step 1: Sizing: Send the raschel blanket that has been pre-finished into the sizing device for pre-wetting treatment before sizing. The sizing device adopts a spray sizing device that can avoid overwhelming the fluff of the blanket. The sizing device is opposite to the pull Scheer blanket sprays white slurry, which is composed of synthetic thickener, water and penetrant, with a viscosity of 500-3000CPS, of which, in each liter of white slurry, thickener accounts for 10 grams, penetrant accounts for 2 grams, and the rest is water .

[0059] Step 2: The Raschel blanket that has been sized is sent to the digital inkjet printing machine for inkjet printing. The specific printing process is: transfer the designed pattern into the computer software, and send the sized blanket to the digital printing on the ...

Embodiment 2

[0083] see Figure 7 to Figure 9 .

[0084] This embodiment 2 also provides a digital inkjet printing method for Raschel blankets, the steps of which are the same as those disclosed in embodiment 1, the difference between the two is that the sizing devices used are different. The air knife spraying sizing device is adopted in the present embodiment 2, and the air knife spraying sizing device comprises a frame two 210, a cloth guide roller mechanism two 211, an air knife spraying mechanism, a raw pulp barrel two 216 and a booster pump two 217. Cloth guide roller mechanism 2 211 is installed on the frame 2 210 for guiding and conveying the Raschel blanket; the air knife spray mechanism is located above the cloth guide roller mechanism 2 211 and is used for spraying the Raschel blanket. Pour white slurry. The inlet end of the booster pump 217 is connected with the raw pulp barrel 2 216, the outlet port of the booster pump 217 is connected with the stock tank 212, and the boost...

Abstract

The invention relates to a Raschel blanket digital ink-jet printing method. The method comprises the following steps of 1, performing sizing: feeding a Raschel blanket subjected to pre-finishing treatment into a sizing device, carrying out pre-wetting treatment before sizing, and spraying white paste to the Raschel blanket by the sizing device, wherein the sizing device adopts a spraying sizing device capable of preventing blanket fluff from being pressed down, the white paste is composed of a synthetic thickener, water and a penetrant, and the viscosity of the white paste is 500-3000 CPS; 2, feeding the sized Raschel blanket into a digital ink-jet printing machine for ink-jet printing, wherein the printing procedure of the digital ink-jet printing machine comprises the steps that a designed pattern is called into printing software, the use amounts of all basic ink are automatically matched through an intelligent color matching and ink amount calculation method in the printing software, and the sized Raschel blanket is printed; and 3, feeding the Raschel blanket subjected to ink-jet printing into a pressure infiltration machine for pressure infiltration treatment.

Description

technical field [0001] The invention relates to the technical field of fabric digital printing, in particular to a digital ink-jet printing method for Raschel blankets, and the method is especially suitable for digital printing of high-pile Raschel blankets. Background technique [0002] At present, the printing of raschel blankets is mainly realized by screen printing, including flat screen printing and rotary screen printing. The flat screen is suitable for printing large-size patterns, while the pattern cycle of the rotary screen is generally relatively small, and the speed of the flat screen is relatively round. Internet is much slower. But no matter it is flat screen or rotary screen, there are many disadvantages. For example, whether it is flat screen printing or rotary screen printing, plate making is required, and plate making requires a lot of time. At the same time, the color of each plate needs to be specially spent on color matching. At the same time, the total ...
