Polyester fabrics are usually difficult in dyeing deeply due to their dense structure and high surface refractive index, and deepening finishing is an effective method to obtain dark polyester fabrics. In this article, octamethyl cyclotetrasiloxane (D 4 ), 1,3,5-tris(3,3,3-trifluoropropyl)-methylcyclotrisiloxane (D 3 F), and silane coupling agent KH-902 were used as main monomers to synthesize organic fluorosilicone, and further to prepare cationic organofluorosilicone (COFS) and COFS darkening agent. FTIR and 1 H-NMR were used to characterize the structure of synthetic products. The finishing experiments confirmed that COFS darkening agent had good shade darkening on dyed polyester fabrics with small color change. The optimum conditions of deepening finishing were COFS darkening agent concentration of 20%, the pick-up of 85%, and the curing temperature of 180 °C. After finishing, the dyed fabric had no lowering effect on color fastness, all at grade 4 or above. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019 , 136 , 48208.

The practical application of superhydrophobic coatings is limited by fabrication difficulties, poor mechanical properties, and low durability. In this study, coatings were prepared by blending organofluorosilicon-modified polyurea with hydrophobic nano- to submicron-sized particles, and their post-curing properties were investigated. The results show that under optimal parameters, the coatings exhibited a water contact angle of 151°, a rolling angle of less than 10°, a tensile strength of 12 MPa, and a tensile elongation at break of 220%. Even after 25 cycles of sandpaper abrasion and heating at 100°C for 1 hour, the coatings maintained their superhydrophobic properties, demonstrating excellent acid-alkali corrosion resistance and self-cleaning capability.

The printing and dyeing industry is currently accelerating toward a direction of high efficiency, energy conservation, environmental protection, and integration with digitalization. Disperse dye wash-free digital inkjet dyeing is a revolutionary breakthrough for cleaning and coloring polyester fabric. Based on the solubility parameters and the hot-melt dyeing characteristics of disperse dyes, soft, hard, and functional monomers of acrylate were used as the main body. Moreover, single-vinyl fluorinated polysiloxane and divinyl polysiloxane with low solubility parameters were used as modified monomers. A modified polyacrylate (PFSMA) adhesive containing silicon in the main chain and fluorine silicon in the side chain was prepared via miniemulsion polymerization. Using disperse digital inkjet dyeing of polyester fabric without washing can realize energy saving, emission reduction, and carbon reduction. Results showed that the optimum preparation conditions of PFSMA were as follows: DVFS molecular weight of 957 g/mol and DVFS content of 2.5 wt %. Compared with that of polyacrylate (PA), the glass-transition temperature of PFSMA film decreased, and its water resistance, toughness, and adhesion enhanced. When the PFSMA content in the wash-free disperse red ink was 8 wt %, the color yields of the front and back of the PFSMA jet-dyed polyester fabric were 18.86 and 13.28, respectively. Moreover, the color yield of the front of PFSMA jet-dyed polyester fabric was 39.9% higher than that of the pure liquid disperse red jet-dyed fabric. The simulated fixation rate was 87.9%, approximately 2.9 times higher than that of the PA wash-free jet-dyed fabric. The color fastness to dry rubbing reached level 4 and the color fastness to wet rubbing reached level 3–4, which was one level higher than that of pure liquid disperse red jet-dyed fabrics. The color fastness to soaping reached grade 5 and the color fastness to heat compression reached grades 4–5 and above. The fabric was a little firmer but smoother. The color properties, color fastness, and hand feeling of the PFSMA wash-free jet-dyed polyester fabric exceeded the levels of commercially available adhesives.

Functional thermoregulation fabrics have emerged as a significant area of research and development within the textile industry, garnering extensive attention in recent years. Herein, dodecyl alcohol/paraffin wax-styrene-acrylate emulsions (DD/PW-TiO₂/FSiWSA) were prepared using the core-shell emulsion polymerization method and used for the finishing of linen fabrics. To address the issues of low solid content, insufficient stability, and poor water resistance in water-based styrene-acrylic emulsions (WSA), nano-TiO₂ was first modified with 3-methacryloxy propyl trimethoxysilane (KH-570). Subsequently, KH-570 modified nano-TiO₂ and organic fluorosilicon were simultaneously introduced into the polymer skeleton. The structural characteristics of DD/PW-TiO₂/FSiWSA were studied. The results shows that the DD/PW-TiO₂/FSiWSA coating increases the water contact angle (WCA) of linen fabric from 0° to 131.95°, while also providing excellent stain resistance. The modified fabric has excellent anti-UV properties, and the UV protection factor is as high as 56.16. Moreover, the modified fabric exhibited excellent antibacterial activity against A. niger and S. aureus . Encouragingly, the modified fabric has excellent heat storage and temperature regulation capability, with a peak phase transition temperature of 23.6 °C, a latent heat of fusion of 25.36 J/g, and a 65.9 % increase in thermal conductivity. The coating is universal and can enhance the hydrophobicity of materials such as cotton fabrics, polyester cotton, paper, cardboard and wood, with a WCA range of 115.56° ~ 131.72°. Therefore, this multifunctional coating will lead cellulose materials towards diverse applications.

In this study, we present a method to enhance the hydrophobic properties of organofluorosilicon styrene–acrylate emulsions while simultaneously reducing their environmental pollutional, and assess their potential for applications in oil–water separation materials, waterproof coatings, and related fields. We achieved this by developing organofluorosilicon styrene–acrylate emulsions with core–shell interpenetration properties through a meticulously designed preemulsified semicontinuous seed emulsion polymerization process. In addition, we have added sodium lignosulfonate, a green and renewable material, to the polymerization process to further enhance the environmental sustainability of these emulsions. A comprehensive characterization of the lignin-modified emulsions was conducted using various techniques, including assessments of storage stability, centrifugal stability, ionic stability, water contact angle, thermogravimetric analysis, Fourier transform infrared spectroscopy, as well as scanning and transmission electron microscopy analyses. The findings revealed that the lignin-modified emulsions exhibited similar stability to conventional phenylpropylene emulsions in terms of Ca 2+ , mechanical, and storage stability, while demonstrating notably enhanced thermal stability and hydrophobicity. Significantly, immersion of filter paper in the modified emulsion resulted in filter paper with markedly improved hydrophobic properties, while retaining surface pores and preserving filter capacity. This underscores the potential of lignin-modified emulsions for application in oil–water separation materials. Furthermore, this innovation led to a noteworthy 50% reduction in the usage of organofluorosilicone monomers, thereby mitigating potential hazards and environmental pollution associated with their use. Our utilization of sodium lignosulfonate as a modifier for organofluorosilicon styrene–acrylate emulsions represents a novel and promising approach for applications in oil–water separation and waterproof coatings. The integration of green and sustainable materials has significantly advanced environmentally friendly solutions, fostering more eco-conscious practices in industrial and commercial applications.
