Low-gram-weight digital ink jet transfer printing base paper and production method thereof

Abstract

The invention provides low-gram-weight digital ink jet transfer printing base paper and a production method thereof, and discloses the low-gram-weight digital ink jet transfer printing base paper which comprises base paper and a thermal transfer coating, wherein production raw materials comprise bleached chemical hardwood pulp, bleached mechanical bamboo pulp, precipitated calcium carbonate, glyoxylic acid modified polyacrylamide, an internal sizing agent and other functional additives; the coating comprises micron silica, nano calcium carbonate, crosslinked chitosan and an alkyl ketene dimer(AKD), and the base paper has a certain weight of 25-40g / m<2>. According to the invention, the crosslinked chitosan and the alkyl ketene dimer are matched with micro-nano inorganic pigments to be used, and the micro-coating technology is adopted to produce the low-gram-weight heat transfer printing base paper, by use of the micro-nano coating with a high specific surface area, absorption of high ink jet amount of ink can be achieved by a small coating amount, and the situation that the ink cannot be transferred to a fabric after penetrating into the base paper can be prevented, so that the ultra-low-gram-weight heat transfer printing base paper has the advantages of high drying rate, high transfer rate, uniform transfer printing, economy, environmental protection and the like.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a transfer printing base paper and a production method thereof. Background technique [0002] Transfer printing is one of the more popular printing methods today. Its advantages are artistic patterns, fine outlines, clear layers, lifelike shapes, relatively simple processing, and no pollution, less investment, energy saving, and small equipment footprints. Transfer printing is to print the dye on the transfer printing paper first, and then transfer the dye from the transfer printing paper to the textile through heat treatment, so as to form the desired pattern on the textile. [0003] At present, digital printing technology has replaced part of the gravure printing process, but it is limited due to the high cost of consumables. Generally, the base paper of digital printing paper is 60-90 grams per square meter, while the traditional gravure printing paper is only 30-40 grams...

AI Technical Summary

Problems solved by technology

However, the weight of the coating needs to increase the thickness of the coating during coating, which will easily cause the base paper to be saturated with a large amount of water, resulting in arching, folding, and seersucker. Therefore, a large coating amount cannot be well applied on low-weight base paper. accomplish

Due to this contradiction, none of the existing low-weight digital printing papers in the market can carry high ink well, and their application range is very limited.
