The polyurethane modified organic silicone (PU-SA) was successfully synthesized via step-by-step polymerization with isophorone diisocyanate (IPDI) and polypropylene glycol (PPG) used as monomers, dibutyltindilaurate (DBTDL) as the catalyst, trimethylolpropane (TMP) and N-methyldiethanolamine (MDEA) as the chain extender, and amino-terminated siloxane (SA) as the blocking agent. The chemical structure of PU-SA was characterized by Fourier transform infrared spectroscopy (FT-IR). X-ray photoelectron spectroscopy (XPS) and scanning electron microscope (SEM) showed that PUSA had been successfully finished on the surface. Additionally, the thermogravimetric analysis (TGA) demonstrated that the PU-SA treated fabrics showed low decomposition temperature and slightly high char residue. As a finishing agent, the effect of PU-SA on the handle of cotton fabrics was also studied by using a Kawabata Evaluation System for Fabrics (KES-F). The experimental results found that PU-SA had a significant improvement on the bending properties, surface properties, and compressional properties. Moreover, the mechanical and anti-wrinkle properties of the cotton fabrics were also enhanced.

Aqueous emulsion polymerization prepared a nano-SiO 2 polyacrylate fluorine-free anti-fouling finishing agent in this study. The finishing agent was prepared by copolymerizing nano-SiO 2 modified by KH-570 silane coupling agent with 3-[Tris(trimethylsilyloxy)silyl]propyl methacrylate (M3T) and stearyl methacrylate (SMA). The polymer emulsion has a uniform particle size distribution and can meet the use temperature below 160 °C. It also has good stability under solid acid/alkali conditions. The prepared anti-fouling finishing agent was applied to the cotton fabric by a two-dip and two-roll finishing process, and a polymer film containing nanoparticles can form on the surface of the cotton fiber. The experimental results showed that the finished cotton fabric’s apparent roughness increases, making it superhydrophobic. The water contact angle of the finished cotton fabric is 159 °, and it is still not lower than 150 ° after 10 washing cycles and 50 abrasion cycles. At the same time, it also has an excellent water-repellent function, and the spray test score reaches 100 (iSO-5). In addition, the coffee grounds sprinkled on the surface of the finished cotton fabric can roll off with the droplets, showing its self-cleaning ability. Most importantly, it has a specific anti-vegetable oil function because common vegetable oil can stay on its surface for 5 min without thoroughly wetting. It is worth noting that the preparation process is economical, environmentally friendly, and fluorine-free.

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.

Functional textiles are widely concerned because of their potential applications in various fields, water-repellent textiles play a vital role in functional textiles because of their huge practical needs. However, the realization of water-repellent finishing agent with high stability and heat resistance has remained an open challenge, limiting the further application of water-repellent textiles. Herein, waterborne polyurethane (WPU) is prepared by introducing C = C bonds into polyurethane (PU) side chains using trimethylolpropane monoallyl ether (TMPME) as a grafting agent by self-emulsification. As a seed emulsion, WPU is further copolymerized with acrylate monomers to prepare waterborne polyurethane/acrylate (WPUA). Interestingly, the WPUA emulsions with obvious core–shell structure exhibit excellent storage stability and heat resistance, which can cover the fabric surface and form a thin film. The static contact angle up to 151° imparts excellent water repellency to the fabric. Thus, a water-repellent finishing agent was successfully assembled, which possesses high reference value for designing and preparing such materials. Graphical Abstract

Core-shell fluorinated acrylate copolymers emulsion was thus synthesized via the core-shell emulsion polymerization with the fluorinated monomers and acrylic monomers as the main raw materials and its properties were studied. PFMA, the fluorinated acrylate monomers, was synthesized by the esterification of perfluorooctanoyl chloride (PFOC) and hydroxypropyl methacrylate (HPMA). Then the core-shell fluorinated acrylate copolymers emulsion with a poly(MMA/BA/St) core and a poly(PFMA/MMA/BA) shell was synthesized via a starved semi-continuous core-shell emulsion polymerization method by using KPS and sodium bicarbonate as the initiator/buffer system and SDS/Twain 80 as the commixture emulsifier. Lastly, the synthesized copolymers was applied as textile finishing agent for cotton textile. The results of FT-IR and NMR indicated that PFMA had been synthesized as expected and effectively combined in the emulsion copolymerization. The GPC, zeta potential, TEM and DSC showed that the particles had uniform spherical core-shell structure with a diameter of 65-150 nm, and the distribution and emulsion stability was satisfactory. As XPS, FESEM and AFM shown, a hydrophobic structure which was similar to the structure of the lotus leaf were formed and the surface hydrophobicity of the films can be improved. Based on the analysis of DSC, thermal stabilities of the films were enhanced with the increase of fluorine content. Besides, FESEM of textiles showed that the surface of treated textiles were smooth and the edges were clear and visible, indicating significant improvement of the performance on water and oil repellent.

A fluorine-free waterproof and antifouling finishing agent for acrylate was prepared using a simple emulsion polymerization method to optimize the addition amount and ratio of oxidant and reductant in the redox system. The finishing agent is copolymerized by Tris(trimethylsiloxy)silylpropyl methacrylate (M3T), stearic methacrylate (SMA) and glycidyl methacrylate (GMA). The polymer emulsion has an average surface tension of 19.8 mN/m and has good dilution, acid and alkali stability, and thermal stability and can withstand a use temperature below 170 °C. The experimental results show that the finishing agent can form a uniform polymer film on the cotton fabric’s surface. The finished cotton fabric has excellent waterproof performance: a water contact angle of 147°, a spray test grade of 4.5, and a resist water-borne pollution performance grade of 4–5. It is worth noting that the water contact angle is still more than 140° after 20 washing cycles, indicating that the cotton fabric has good washing resistance. At the same time, following the green sustainable development, although the finishing agent does not contain fluoride that endangers the human body and the environment, it can repel the pollution of some ordinary vegetable oils, and the antifouling grade can reach 4.

Mesoporous silica nanocapsules containing a series of fragrances were successfully prepared through an interfacial sol–gel process of tetraethoxysilane (TEOS) in miniemulsions. The hydrophobic liquid droplets of TEOS and fragrance worked as soft templates for forming a capsule morphology. The fragrance/silica nanocapsules were used to aromatically finish polymer films through drying a mixed emulsion of the fragrance/silica nanocapsules and polymer latex particles. The fragrance/silica nanocapsules were homogeneously distributed in the composite films. The release of fragrances from the composite film displayed a sustained manner. The introduction of the fragrance/silica nanocapsules could influence the thermal and mechanical properties of the composite films.

The research in textiles is being driven by economy and functionality. Therefore, the present research is focused on the development of multifunctional textiles with simple process. Herein, a highly efficient multifunctional linen fabric finishing agent was developed with nano-ZnO, dodecafluoroheptyl methacrylate, vinyl trimethoxysilane, methyl methacrylate, and butyl acrylate as raw materials. The finishing agent imparted linen fabric multiple performance characteristics such as hydrophobic, antibacterial and ultraviolet protection. Infrared spectroscopy analysis, particle size test and transmission electron microscopy were used to analyze the main characteristics of multifunctional linen fabric finishing agent, including the main groups, particle size distribution and particle morphology. The results showed that the nano-ZnO/fluorosilicone-polyacrylate emulsion finishing agent had been successfully prepared, and the finishing agent had good stability. By means of scanning electron microscopy, thermogravimetry, and X-ray diffractometry, it was found that the finishing agent successfully covered the surface of the linen fabric, which increased the thermal decomposition temperature of the linen fabric and reduced the crystallinity of the linen fabric, indicating that improved the heat stability and softness of the fabric. Similarly, the application performance of linen fabric was tested. Compared with the original linen fabric, the finished linen fabric had good ultraviolet protection, antibacterial, hydrophobicity, washing fastness and breaking strength, leading to the improvement of the wear performance of linen fabric. Thus, the multifunctional linen fabric finishing agent has the advantages of simple technology, low cost and promising prospect.
