“…Compared with the control system (single in situ polymerization), silica nanoparticles were dispersed uniformly in the outer layer of the resultant nanocomposite films. Furthermore, polyacrylate/TiO 2 nanocomposite was prepared via double in situ polymerization [49]. Results revealed that TiO 2 particles were mainly dispersed on the outer layer of latex particles.…”

Nowadays, the increasing demands from consumer challenges the traditional leather products. Traditional polymer leather finishes gradually lose their dominant position in the market. To address this issue, recent research effort has been devoted to developing polymer-based organic-inorganic nanocomposite leather finishes due to their various functional properties including antibacterial, self-cleaning and water-resistant property. In this review, we provide a comprehensive overview of synthesis of polymer-based organic-inorganic nanocomposites and their application as functional leather finishes. With the perspective of their properties and current challenges, an outlook in the future development about crafting functional and high-quality leather finishes are further proposed.

“…Compared with the fabric sample treated with fluorinated polyacrylate soap‐free latex, the fabric samples treated with nano‐TiO 2 /fluorinated polyacrylate soap‐free hybrid latex exhibited stronger antibacterial activity. This result can be attributed to the destruction of the bacteria cell wall and membrane by the reactive oxygen species, which is the consequence of photocatalytic effect of nano‐TiO 2 particles . In addition, the antibacterial rate of the treated fabric samples increases with the increase of modified nano‐TiO 2 content from 0 wt% to 0.3 wt%.…”

Nano-TiO 2 /fluorinated polyacrylate hybrid latex was prepared by soap-free emulsion polymerization using reactive emulsifier. With the increase of modified nano-TiO 2 content, the monomer conversion gradually decreased while the gel rate slowly increased accordingly. The transmission electron microscopy (TEM) and dynamic light scattering (DLS) analyses indicated that the core-shell latex particles were uniform with narrow size distribution. In addition, the hybrid film formed from nano-TiO 2 /fluorinated polyacrylate latex presented higher thermal stability, mechanical and UVshielding performance than the film formed from fluorinated polyacrylate latex. Scanning electron microscopy (SEM) and water contact angles (WCA) analyses confirmed that the surface of hybrid film was slightly rough and hydrophobic. Furthermore, the energy dispersive X-ray (EDX) analysis revealed that the organic fluorine segment had the tendency to migrate to the film-air interface. At last, the results of the antibacterial activity and WCA showed that the cotton fabric treated with nano-TiO 2 /fluorinated polyacrylate hybrid latex possessed good antibacterial property and remarkable water repellency.

“…Compared with the spectrum of sample H3-0 ( Figure 2 a), there were no evident absorption peaks around 1100, 873 and 725 cm −1 in the spectra of samples with back-coating (H3-1 and H3-2). In addition, both H3-1 and H3-2 exhibit new characteristic absorption peaks: stretching of the carbonyl group C=O around 1732 cm −1 [ 35 , 36 ], distortion vibration of CH 2 at 1452 cm −1 [ 37 ], and the stretching vibration of C–O–C, C–C and C=O in the acrylic group at 1166, 962 and 843 cm −1 , respectively [ 38 ]. All these characteristic absorption peaks indicate that the polyacrylate latex was successfully coated on the backside of samples H3-1 and H3-2.…”

Fiber shedding is a critical problem in biomedical textile debridement materials, which leads to infection and impairs wound healing. In this work, single fiber pull-out test was proposed as an in vitro evaluation for the fiber shedding property of a textile pile debridement material. Samples with different structural design (pile densities, numbers of ground yarns and coating times) were prepared and estimated under this testing method. Results show that single fiber pull-out test offers an appropriate in vitro evaluation for the fiber shedding property of textile pile debridement materials. Pull-out force for samples without back-coating exhibited a slight escalating trend with the supplement in pile density and number of ground yarn plies, while back-coating process significantly raised the single fiber pull-out force. For fiber shedding mechanism analysis, typical pull-out behavior and failure modes of the single fiber pull-out test were analyzed in detail. Three failure modes were found in this study, i.e., fiber slippage, coating point rupture and fiber breakage. In summary, to obtain samples with desirable fiber shedding property, fabric structural design, preparation process and raw materials selection should be taken into full consideration.
