“…As we all know, a fluorinated compound can reduce surface tension. 33,34 The surface wetting behaviors of the FSi-PAcr/PB hybrid latex films on a glass slide were identified by the method of contact angle measurement, using de-ionized water. The WCAs of hybrid pigment latex films are shown in Figure 9.…”

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.

“…Silicone resin dispersions (SIL 1 and SIL 2) were synthesized according to the procedure described in [29], although different functional silanes were used along with D4 as silicone monomers-see Figure 2 for the structures of these silicone monomers.…”

“…It has been proved in a number of research papers both referred to in that review paper and published later that the unique properties of coatings like e.g., high surface hydrophobicity and water resistance combined with enhanced water vapour permeability and good mechanical properties can be achieved by applying methods (1) to (3) described above to synthesize hybrid dispersions containing silicones where monomer X is acrylic monomer and monomer Y is silicone monomer-see e.g., [18][19][20][21] for method (1), [22][23][24] for method (2) or [24][25][26] for method (3). If fluoroacrylic monomer was used as monomer X [27][28][29][30], the surface hydrophobicity of coatings could be improved even more. It was also proved in our earlier studies [31][32][33] that the application of method (1) to emulsion polymerization of methyl methacrylate in aqueous silicone resin dispersions led to stable "core-shell" silicone-poly(methyl methacrylate) hybrid dispersions which, after drying, produced corresponding "nanopowders" that were later used as very effective impact modifiers for powder coatings.…”

The objective of the study was to investigate the effect of the method of synthesis on properties of aqueous hybrid silicone-acrylic (SIL-ACR) and acrylic-silicone (ACR-SIL) dispersions. SIL-ACR dispersions were obtained by emulsion polymerization of mixtures of acrylic and styrene monomers (butyl acrylate, styrene, acrylic acid and methacrylamide) of two different compositions in aqueous dispersions of silicone resins synthesized from mixtures of silicone monomers (octamethylcyclotetrasiloxane, vinyltriethoxysilane and methyltriethoxysilane) of two different compositions. ACR-SIL dispersions were obtained by emulsion polymerization of mixtures of the same silicone monomers in aqueous dispersions of acrylic/styrene copolymers synthesized from the same mixtures of acrylic and styrene monomers, so the compositions of ACR and SIL parts in corresponding ACR-SIL and SIL-ACR hybrid dispersions were the same. Examination of the properties of hybrid dispersions (particle size, particle structure, minimum film forming temperature, Tg of dispersion solids) as well as of corresponding coatings (contact angle, water resistance, water vapour permeability, impact resistance, elasticity) and films (tensile strength, elongation at break, % swell in toluene), revealed that they depended on the method of dispersion synthesis that led to different dispersion particle structures and on composition of ACR and SIL part. Generally, coatings produced from hybrid dispersions showed much better properties than coatings made from starting acrylic/styrene copolymer dispersions.

“…This phenomenon was ascribed to the migration of silicon‐containing segments to the film‐air interfaces. The consequent low concentration of silicon at the film‐PET interfaces generated a high affinity of binder film for the diffusion of disperse dye molecules 45‐49 . An effective way to solve this problem is the usage of crosslinkable binders that can significantly restrain the migration of polymer chains 50‐54 …”

The printing of polyester (PET) fabrics using binders and disperse dyes is an environmentally less harmful technique due to the exclusion of water‐intensive washing processes. Unfortunately, the conventional polyacrylate (PA) binders are inapplicable for this printing technique as the high PA‐disperse dye compatibility restrains the migration of disperse dye molecules from binder films into PET fabrics. Herein, we demonstrate a rational design and synthesis of novel PA binders by copolymerizing fluorosilicone monomers with multi‐vinyl groups for the sustainable printing of PET fabrics. The incorporated fluorosilicone functionalities significantly decrease the solubility parameter of PA, facilitating the dye molecules migration toward PET fabrics. Meanwhile, the crosslink structure formed via vinyl groups restrains the migration of polymer chains and thus allows for the anchor of F/Si segments, enabling the continuous migration of disperse dyes. As a result, both the utilization ratio of disperse dyes and the color yield and fastness of printed PET fabrics are substantially improved. Moreover, the washing‐free printing process using the developed binder can reduce 73% of water consumption, 74% of energy input, and 100% of wastewater discharge over the traditional printing process. Our study may provide insights into rational design of binders for the sustainable printing of PET fabrics.
