“…Similar to our study, COS-O-terpineol showed minimal antibacterial effect against E. coli [48]. The antibacterial effect of viscose fiber-silkworm pupa COS against S. aureus was not significant either [49]. The result in this study demonstrates that the introduction of OSA could promote the antimicrobial actions of COS.…”

The synthesis of octenyl-succinylated chitosan with different degrees of substitution resulting from chemical modification of chitosan and controlled addition of octenyl succinic acid was investigated. The modified products were characterized using 1H NMR, FTIR, and XRD, and the degree of substitution was also determined. The properties of the modified chitosan oligosaccharide in solution were evaluated by surface tension and dye solubilization, finding that the molecules self-assembled when they are above the critical aggregation concentration. The two methods yielded consistent results, showing that the self-assembly was reduced with higher levels of substitution. The antimicrobial activity of the octanyl-succinylated chitosan oligosaccharide (OSA-COS) derivatives against Staphylococcus aureus, Escherichia coli, and Fusarium oxysporum f.sp cucumerinum was investigated by the Oxford cup method. While the acetylated COS derivatives were not significantly effective against either E coli or S. aureus, they showed significant antifungal activity toward F. oxysporum that was superior to that of COS. The modified product was found to form a stable emulsion when mixed with whey protein isolate. The emulsion formed by the highly substituted derivatives have a certain stability and loading efficiency, which can be used for the encapsulation and delivery of astaxanthin.

“…As a regenerated cellulose fibre, the chemical structure of viscose is similar to cotton. 1,2 Therefore, viscose displays excellent application performance, similar to cotton fabric. For example, its hygroscopicity, air permeability, biodegradability and lack of static electricity (neutrality towards charge build-up) meet the physiological requirements of the human body.…”

The traditional dyeing process of reactive dyes requires a large amount of inorganic salts to accelerate the combination of dyes and textiles, which leads to substantially more water pollution. In this work, we used a quaternary ammoniumtype cationic modifier, 3-chloro-2-hydroxypropyl trimethylammonium chloride (CHPTAC), to modify the viscose acetal fibre before the dyeing process. After the modification, reactive dyes were dyed without any inorganic salt. Then the fabric was finished with a commercial wet rubbing fastness enhancer, FM-8, to improve the colour fastness. The modified viscose acetal fibre was characterised by Fourier Transform-infrared spectroscopy and scanning electron microscopy. The results showed that viscose acetal fibre was modified successfully by CHPTAC and that the physical structure did not noticeably change following the modification. The optimum process was determined by establishing the ideal amount of modifier and the modification temperature, as well as the concentrations of sodium hydroxide and soda ash. The results show that the most suitable parameters were 80 g/L for the modifier dosage, a modification temperature of 70°C, 20 g/L of sodium hydroxide and 10 g/L of soda ash. The wet rubbing fastness was grade 4-5 after finishing and dyeing. The exhaustion percentage was significantly higher than that for traditional dyeing, and the K/S and dyeing uniformity were both higher than traditional salt dyeing.How to cite this article: Li, Zhai S, Dong W, et al.
