WebAug 14, 2024 · Preparation of the crosslinked regenerated cellulose films. The GA-assisted crosslinking of the RC films was carried out through different strategies. The first one is crosslinking in solution. Namely, once cellulose was completely dissolved in the solvent system, 10 mL GA solution with a concentration of 2 vol% was added. WebHence, DI sample with uncrosslinked cellulose has more hydroxyl group compared to crosslinked cellulose. From Table 1, calculation of the total area for O–H band at 3300 cm ˗1 to the bending vibration of C–H at 1460 cm ˗1 bands showed that the ratio of these bands decreased as the percentages of both crosslinkers increased. WebIn a summary, nonionic crosslinker was applied in the Lyocell surface treatment to diminish the fibrillation behavior. From the fibrillation degree measurement using Martindale abrasion machine and SEM measurement, the nonionic crosslinker could crosslinked cellulose macromolecular chains to reduce the fibrillation tendency. matthew dempsey attorney
