Features of printing textile materials with pigments and the use of water dispersions of synthetic copolymers

Abstract

In pigment printing, a pressing issue is the search for new binders for printing inks. The work examines the search for accessible and cheap polymer preparations that have cross-linking properties and are capable of forming strong, elastic and transparent films to create an effective low-component and environmentally friendly pigment printing technology. The use of polyurethane dispersions in various proportions with additional cross-linking agents has been studied. They used methazine, carbamol GL, and PVA. For the Aquapol - Methazine mixture, it is necessary to use the ratio with the lowest content of thermosetting resin precondensates. When using PVA, the optimal ratio is 1:1. When adding Aquapol 12, the color fastness to dry rubbing and washing is 5 points. PVA increases the adhesion of the print to the fabric. In the case of PVA, the fingerboard is softer. With increasing concentration of PVA in the composition, the hardness either does not change or decreases. After modification of polyurethane dispersions with PVA, its use is economically beneficial.
