Degumming is the most important link in the textile industry. The main purpose of degumming is to effectively remove non-cellulose substances in plant bast fibers. In this research, we propose an electro-Fenton (EF) system with a nickel-foam (Ni-F) cathode in weak acid pH (EF/Ni-F) to degum cannabis fiber in EF while reducing the content of pollutants in degumming wastewater. FT-IR, XPS, XRD, SEM, and TG were employed to thoroughly understand the reaction characteristics to characterize chemical components, element qualities, the crystallinity, and the morphologies of degummed fibers. Additionally, physical and mechanical properties such as breaking strength, elongation at breaking, residual glue rate, whiteness, and diameter of degummed fibers were measured. Through testing, it was found that the fiber degummed by the EF method had higher breaking strength, lower residual tackiness, and higher whiteness than other methods. The antibacterial test was used to detect the effect of fiber on Staphylococcus aureus before and after degumming. EF could remove more colloidal components from cannabis than other methods, and the mechanical properties were also enhanced. The characteristics of the degummed fiber further confirmed the effectiveness of the new degumming method. Moreover, the antibacterial experiment found that the antibacterial property of the degummed fiber was enhanced. The colloidal components in the degumming wastewater were flocculated and precipitated. The upper liquid of the solution had low chromaticity, low COD value, and weak acid pH value, which can meet the discharge requirements. The above test proves that EF is an effective degumming method that is environmentally friendly, takes less time, and enhances antibacterial performance.

“…If performing the degumming process parameters is not monitored accurately, the effect of oxidation reaction of alkaline oxidation degumming is so powerful that it is also possible to dissipate the cellulose molecule chains. However, if the implementation of intemperate oxidation reaction during the fiber degumming process, then the probability is so high to vandalize degummed fiber as well as its mechanical properties [72].…”

Sericin is a sticky protein substance, which is generated by the silk-worm for holding the filaments of silk tightly. The main constituent of natural crude silk is made up of sericin and fibroin. Fibroin and sericin play a vital role in increasing the strength, stiffness and on maintaining the constructional integrality of the cocoon. This review reports the role of several types of degumming agents for the removal of sericin from silk surfaces and an overview of silk fibroin approaches in the tissue engineering field. The prime factors responsible for the removal of sericin (degumming) from silk were systematically analyzed and discussed. The key factors affects on modification of the silk surface are includes surfactant, degumming time, temperature, advanced techniques such as ultra-sonication, microwave radiation, infrared radiation, low-temperature oxygen plasma radiation, and PH. These factors influence either individually or cumulatively at the degumming process. Tissue engineering is an emanate and most optimistic approach to restore tissue malfunction by adopting the concept of the technology being practiced using numerous biomaterials, cells, and the nutrient-specific growth factors. Different types of materials include various bio-material and mainly of silk fibroin constituent of it is conceding most optimistic biomaterials in tissue engineering application. Silk fibroin is a naturalistic protein-based polymer with an eminent physiochemical characteristic, are magnificent biocompatibility, amenable biodegradability, proper oxygen, and water-vapor permeability, and least inflammatory reaction. The critical studies accomplishing on the role of Silk fibroin and various approaches adopted in the degumming process is extensively reviewed and reported.

Degumming is the dominant method for insolating lignocellulosic fibers in textile applications. Traditional alkaline degumming (TAL), as a common method, requires a high-concentration alkali and has been a severe challenge to the environment. In the research reported here, the possibility of innovative jute degumming by organic solvents 1-2 propylene glycol and a combination of additive green oxygen (GO-OS) was studied. The results revealed that fibers could be extracted by this system (under condition of 0.9% GO-OS, 180°C, 120 min), and obtained fibers with higher breaking tenacity (7.1 cN/dtex), yield (65.7%), breaking elongation (2.87%) and residual gum (11.7%), which all meet the requirement of the relevant Chinese Textile National Standards. Notably, the required reaction time (120 min) of the GO-OS system was 180 min shorter than that of the TAL method. Furthermore, the modifications introduced by the degumming effect on physicochemical aspects were characterized and confirmed by Fourier transform infrared spectroscopy, scanning electron microscopy and X-ray diffraction. This study provides a promising degumming method for separating jute lignocellulose without acid and alkali consumption.
