preparation example Construction

[0045] In the present embodiment, the preparation method of polyacrylamide stock paste comprises:

[0046] S1: Weigh 4-9% of acrylamide by weight, 0.25-0.50% of ammonium persulfate relative to acrylamide, 0.25-0.50% of residual ammonium persulfate treatment agent relative to acrylamide, 2-5 % of polyacrylamide viscosity remover, deionized water, the sum of the above components is 100%.

[0047] S2: Dissolving the weighed acrylamide and ammonium persulfate in deionized water to make a reaction solution;

[0048] S3: adding the reaction solution prepared by S2 into the reaction kettle under stirring;

[0049] S4: Raise the temperature of the reactor to 60-80°C for 1-2 hours;

[0050] S5: Add the residual ammonium persulfate treatment agent weighed in S1 into the reaction kettle for reaction, and stir for 10-30min;

[0051] S6: Add the polyacrylamide viscosity remover weighed in S1 into the reaction kettle for reaction, and stir for 10-30 minutes, then cool the reaction kettle...

Embodiment 1

[0055] In Example 1 of the present invention, take 33L of polyacrylamide raw paste with an average molecular weight of 880,000 and an average viscosity of 89,000mpa·s, put it into the chemical tank, turn on the agitator, the speed of the agitator is 400rpm, and add 64L of deionized Water and 3L emulsified oil were stirred for 15 minutes to obtain a polyacrylamide paste; 10g of brown acid dye was completely dissolved in 2L of boiling water to obtain a dye solution, cooled to room temperature, filtered through a sieve and evenly added to the polyacrylamide paste. Stir for 15 minutes to obtain the color paste. The average viscosity of the color paste is 195mpa s, the average water holding capacity is 0.48cm / 15min, and the average printing viscosity index PVI is 0.855. The speed of the printing equipment is set to 65cm / min, and the pressure is set to 1.5MPa. Inkjet printing on 1000 grams of nylon wool blank blanket, the printing effect is as follows figure 2 shown.

Embodiment 2

[0057] In Example 2 of the present invention, take 32L of polyacrylamide raw paste with an average molecular weight of 860,000 and an average viscosity of 84500mpa·s, put it into the chemical tank, turn on the agitator, the speed of the agitator is 400rpm, add 65L of deionized Mix water and 3L emulsified oil for 15 minutes to obtain polyacrylamide paste; completely dissolve 10g of dark blue acid dye in 2L of boiling water to obtain a dye solution, cool down to room temperature, filter through a sieve and evenly add to polyacrylamide paste , stirred for 15 minutes to obtain the color paste, the average viscosity of the color paste is 185mpa s, the average water holding capacity is 0.51cm / 15min, the average printing viscosity index PVI is 0.840, the speed of the printing equipment is set to 65cm / min, and the pressure is set to 1.6MPa , inkjet printing on 1200 grams of nylon wool blank blanket, the printing effect is as follows image 3 shown.

Abstract

The invention discloses an ink-jet printing method for a nylon wool carpet, belongs to the technical field of ink-jet printing of carpets, and can solve the problems that existing paste is difficult to dissolve and degrade. The method comprises the following steps of putting quantitative polyacrylamide raw paste into a material melting barrel, and adding deionized water and emulsified oil under a first stirring condition to obtain a polyacrylamide paste material with the viscosity of 150 to 250mpa. S; adding a dye into boiling water under a second stirring condition, stirring until the dye is dissolved, and standing and cooling to obtain dye liquor with the dye content of 4 to 6g / L; taking quantitative dye liquor in S2, and adding the dye liquor into the polyacrylamide paste in S1 under the first stirring condition to obtain a color paste; and carrying out ink-jet printing on the nylon wool carpet by using the color paste.

Description

technical field [0001] The invention relates to an ink-jet printing method for nylon wool carpets, belonging to the technical field of carpet ink-jet printing. Background technique [0002] Printing paste is an indispensable product for inkjet printing of nylon wool carpets. Sodium alginate and carboxymethyl starch are ideal pastes for reactive dye printing, but they are not suitable for acid dye printing used in nylon wool carpet printing. [0003] Existing ink-jet printing paste for nylon wool carpets uses polycarboxylic acid polymers, which have the following disadvantages: 1. It is difficult to melt the paste. When melting the paste, it is necessary to use an emulsifier to emulsify the original paste for more than 30 minutes. The paste contains unemulsified particles, which are easy to block the nozzle during inkjet and need to be shut down for cleaning, which affects the quality and production efficiency of carpet printing; 2. It is difficult to degrade, and the paste ...
