Water soluble woven bag printing ink

Abstract

The invention relates to the technical field of woven bag production, in particular to water soluble woven bag printing ink. The water soluble woven bag printing ink comprises the following ingredients: 40-70 parts of water soluble acrylic emulsion, 25-45 parts of water-based colour paste, 15-20 parts of polystyrene, 1-3 parts of surfactant, 0-1 part of a defoaming agent and 1-15 parts of water, wherein the surfactant is sulfated castor oil; the defoaming agent is non-silicon polyether mineral oil; and the water based colour paste comprises the following ingredients (in percentage): 10-20% of water soluble acrylic resin, 4-6% of a dispersant, 0.5-1.5% of a defoaming agent, 28-65% of pigment and 10-40% of water, wherein the dispersant is glycerol monostearate, and the defoaming agent is the non-silicon polyether mineral oil. The water soluble woven bag printing ink has clear printing effect as well as relatively high wear resistance and rub resistance and can be widely applied to printing of woven bags.

Description

Technical field [0001] The invention relates to the field of woven bag production technology, in particular to a water-soluble woven bag ink. Background technique [0002] At present, there are two main types of common water-based inks used, namely traditional water-based inks and traditional alcohol-soluble inks. They all use ammonia as the resin modifier and water and alcohol as the main solvents, but the traditional water-based inks are not water-resistant. The traditional alcohol-soluble ink is expensive and toxic, especially when the traditional water-based ink prints various patterns, characters and symbols on the woven bag, its adhesion fastness is poor, unclear, and poor wear resistance , Poor resistance to rubbing, can not meet the requirements of printing on woven bags. Summary of the invention [0003] In order to make up for the shortcomings of the prior art, the water-soluble woven bag ink described in the present invention not only has clear printing effect on woven...

Problems solved by technology

[0002] At present, there are two main types of common water-based inks used, namely, traditional water-based inks and traditional alcohol-soluble inks. They both use ammonia as the resin modifier and water and alcohol as the main solvent respectively. However, the printed patterns of traditional water-based inks are not water-resistant. Non-toxic, easy to decolorize; while traditional alcohol-soluble inks are expensive and toxic, especially when traditional water-based inks print various patterns, characters and symbols on woven bags, their adhesion fastness is poor, unclear, and poor wear resistance , poor kneading resistance, can not meet the requirements of printing on woven bags
