Cationic core/shell polysiloxane acrylate emulsion: synthesis, film morphology, and performance on cotton pigment coloration

In this paper, acrylate-terminated polysiloxane was synthesized and used as raw materials for the synthesis of cationic core/shell polysiloxane acrylate emulsion, which was applied as binders in the pigment dyeing of cotton fabrics. The experimental results showed that: the cationic core/shell polysiloxane acrylate emulsion in this article is in nano size of 100 nm. During the film formation of the emulsion, there are core-core and shell-shell fusion phenomena between the latex particles, and the same polysiloxane chain aggregates on the surface of the film. When the emulsion is used in the pigment dyeing of cotton fabrics, the dyed cotton fabrics feel soft, and the washing fastness and dry/wet rubbing fastness meet the national quality requirements, as washing fastness can reach grade 4–5, dry rubbing fastness can reach grade 4–5, and wet rubbing fastness can reach grade 4.
