In this study, we developed a novel method to prepare chemical fibers by plasticizing cotton with 1-allyl-3-methylimidazolium chloride (AMIMCl) under high temperature and pressure. Cotton was homogeneously mixed with AMIMCl by kneading in a certain mass proportion. It would be a sheet after hot-pressing and this process could be repeated several ti...

When we took a close up of a single fiber in Fig. 2f, the surface of the fiber was smooth again due to the fact that the cotton fibers were plasticized by AMIMCl under high temperature and pressure.

Phloem biomass has gradually attracted attention for its conversion and utilization due to its fast growth rate and suitability for textile use. Currently, clean methods for separating the chemical components of biomass have attracted attention. In this study, the choline chloride-lactic acid (CLA) and choline chloride-glycolic acid (CGA) pretreatment were developed for kenaf chemical components separation, and the solid residue and regenerated lignin were characterized. The results demonstrated that two acidic deep eutectic solvents (DESs) pretreatment had good removal capacities for lignin and hemicellulose even when the kenaf was not crushed. Under optimal treatment conditions, the retention rates of cellulose were 82.4% and 81.1%, respectively. The cellulose content in the recovery solids residues reached 91.5% and 91.3%, which also resulted in good enzymatic hydrolysis conversion efficiency (85.4% and 84.9%). The regenerated lignin exhibited high purity (91.9% and 90.1%), and low molecular weight (1209 and 1086 g/mol), which was attributed to the amount of ether bonds cleavage in lignin. Meanwhile, the DES exhibited a good ability to recycle and reuse. Overall, acidic DES pretreatment holds promise for efficient fractionation and component utilization of kenaf phloem biomass.
The currently reported methods for preparing cellulose acetate hydrogels use chemical reagents as cross-linking agents, and the prepared ones are non-porous structured cellulose acetate hydrogels. Nonporous cellulose acetate hydrogels limit the range of applications, such as limiting cell attachment and nutrient delivery in tissue engineering. This research creatively proposed a facile method to prepare cellulose acetate hydrogels with porous structures. Water was added to the cellulose acetate–acetone solution as an anti-solvent to induce the phase separation of the cellulose acetate–acetone solution to obtain a physical gel with a network structure, where the cellulose acetate molecules undergo re-arrangement during the replacement of acetone by water to obtain hydrogels. The SEM and BET test results showed that the hydrogels are relatively porous. The maximum pore size of the cellulose acetate hydrogel is 380 nm, and the specific surface area reaches 62 m2/g. The porosity of the hydrogel is significantly higher than that of the cellulose acetate hydrogel reported in the previous literature. The XRD results show that the nanofibrous morphology of cellulose acetate hydrogels is caused by the deacetylation reaction of cellulose acetate.
