Abstract
The application relates to the technical field of antibacterial fabrics, in particular to a flame-retardant antibacterial curtain processing technology. The scheme adopts pure terylene woven fabric as curtain fabric base cloth, carries out surface finishing on the pure terylene woven fabric, and uses polyurethane-acrylic ester composite emulsion as a coloring agent; during preparation, dopamine is grafted on the surface of hexachlorocyclotriphosphazene, and the aminotriamine monomer grafted with dopamine is obtained by utilizing an amidation reaction of P-Cl and dopamine, and is grafted into polyurethane, so that the adhesiveness between the dyeing agent and curtain cloth base cloth can be effectively improved, the antibacterial performance of the product is long-lasting, and the excellent performance can be ensured after repeated washing. Especially, when the curtain cloth is subsequently folded, polyurethane components in the dyeing agent can be better fused with thermosetting glue in the folded edge in the thermosetting bonding process to form stable bonding, so that the curtain cloth is ensured not to be degummed after long-term use.
Description
Technical Field
The application relates to the technical field of antibacterial fabrics, in particular to a flame-retardant antibacterial curtain processing technology.
