Fluorosilicone modified polyacrylate/pigment hybrid latex: Synthesis, properties, and application in binder‐free pigment printing of polyester fabrics

Abstract

Pigment printing of textiles is a kind of environmentally friendly technique of saving water and energy, and emission reduction. Fluorosilicone modified polyacrylate/ pigment (FSi-PAcr/PB) hybrid latex was successfully synthesized via a one-step in situ miniemulsion with subsequent free-radical polymerization and cationic ringopening polymer process, which further improve the hand feeling, permeability, and water-resistance of the pigment printed polyester fabrics. These FSi-PAcr/PB hybrid latex particles were used as the binder-free hybrid pigment in the pigment printing of polyester fabrics. The effects of the weight ratio of 3,5-tris(3,3,3-trifluoropropyl)-1,3,5-trimethylcyclotrisiloxane (D 3 F) and octamethyl cyclotetrasiloxane (D 4 ) on the thermal properties and hydrophobicity of hybrid latex films were studied. The color yield, colorfastness, hand feeling, permeability, and water resistance properties of the binder-free printed polyester fabrics were tested and compared. The results showed that theFSi-PAcr/PB hybrid latex films exhibited higher hydrophobicity and lower glass transition temperature (T g ), in comparison with the control system (without fluorosilicone). The printed fabrics with FSi-PAcr/PB showed a lower stiffness and softer hand feeling, good air permeability, and excellent rubbing fastness compared with the control system. It was considered that the introduction of the fluorosilicone composition into the polyacrylate was prone to shift onto the surface film and coated with a layer of latex film to the surface of the single fiber, retaining the majority of the gaps between fibers.

A silane coupling agent was used as a "bridge" between silicone and acrylic copolymer chains of the nanodroplets during in situ copolymerization.…”

“…One strategy for improving the performance of pigment dyed/printed fabrics is binder-free pigment dyeing/printing of textiles using polymer/pigment hybrid latex. , Several studies have explored the use of emulsion polymerized copolymer-encapsulated pigment hybrid latex particles instead of blended pigment and adhesive latex. − These approaches control the size of pigment aggregation on the quasi-nanoscale and strongly anchor pigment particles in the latex film, as depicted in Figure b. Successful pigment hybrid latex has been reported, but the developed strategies require improvement of their textile pigment dyeing/printing performance to reach equality with the level of chemical dye coloring. , Typically, to further improve the hand-feeling, air-permeability, and other performances of printed fabric, polydimethylsiloxane (PDMS) has been incorporated into copolymer chains owing to its sufficiently low glass transition temperature ( T g ), excellent thermal stability, abrasion resistance, and weather durability. − In our earlier studies, to synthesize PDMS-modified PAcr/pigment hybrid latex, and improve the hand-feeling, air-permeability, and water-resistance of the pigment-printed polyester (PET) fabric, we utilized one-pot in situ mini-emulsion polymerization. Moreover, it was found that the nanoscale polymer-encapsulated pigment hybrid latex formed a discontinuous film, which was evenly wrapped on the surface of single yarns.…”
