“…Additionally, a new absorption peak emerged near 1280 cm −1 , which corresponds to the out-of-plane swinging absorption peak of the −CH 2 − group linked to the carboxymethyl group. 36,41,42 To summarize, it may be preliminarily demonstrated that this DES could undergo carboxymethylation reaction with cellulose.…”

“…The ashing method was used to determine the DS of the sample: a certain amount of dried sample was weighed and placed in a ceramic crucible and put into a muffle furnace, and then the temperature was gradually increased to 700 °C, burned for 1 h, and then removed after cooling. Distilled water was used to transfer all the remaining material in the crucible to a conical flask, and then three to four drops of methyl orange indicator solution were added into the conical flask and titrated with 0.1 M sulfuric acid standard solution.…”

Carboxymethylation-modified cellulose nanofibrils (CMCNF) were prepared from bamboo fibers through a pretreatment process using a ternary deep eutectic solvent (DES) system consisting of chloroacetic acid, urea, and choline chloride. Grinding treatment was also employed. The properties of the resulting CMCNF were characterized using various analytical instruments including a fiber image analyzer, field-emission scanning electron microscope, X-ray diffractometer, and atomic force microscope. The results indicated that ternary DES pretreatment has the capability to carboxymethylate-modify the raw fiber material while maintaining the crystalline structure of cellulose. Additionally, it induced a wetting and swelling effect on the fibers, leading to the successful disruption of strong hydrogen bonds and the rapid production of cellulose nanofibrils during mechanical treatment. The carboxymethylation alteration enhanced the ability of the resultant CNF to disperse and increased the stability of the suspension. Furthermore, extending the duration of DES pretreatment enhances the process of fiber fibrillation and diminishes fiber polymerization. The CMCNF produced exhibited a high aspect ratio, with diameters ranging from 10 to 50 nm and lengths extending to a few micrometers. This study presents a novel approach and concept for producing carboxymethylated nanofibrillated cellulose. It also introduces a straightforward, environmentally friendly, and effective method for mass production of bamboo pulp nanofibrillated cellulose. This advancement is anticipated to enhance the processing and utilization of bamboo fiber resources, thereby contributing to an increased overall value.

As a by-product of bamboo processing, bamboo powder is incinerated or buried due to its ineffective utilization, which contributes to pollution. The large amount of waste bamboo powder generated during the processing of bamboo products cannot be effectively utilized. Meanwhile, multiple recycling leads to the loss of fiber quality of corrugated cardboard (OCC) pulp, reducing the mechanical properties of paper. In an effort to obtain high value from waste bamboo powder, this study pulped it using the kraft process. Scanning electron microscope (SEM) observations showed that the surface of bamboo fiber had more cracks, which made bamboo fiber have better air permeability. The permeability of bamboo paper was 146% that of the OCC. X-ray diffraction (XRD) analysis showed that the crystallinity of bamboo pulp was 133% that of the OCC pulp. The results of physical testing of paper showed that the tensile strength of bamboo paper was 116% that of the OCC. The tear strength of bamboo paper was 61.7% that of the OCC, and the bursting strength of bamboo paper was 59.1% that of the OCC. Based on the above results, bamboo powder can be used as raw material for making OCC pulp.
