“…Based on various literatures and the above studies [3,25,26], the preparation methods of graphene textiles are mainly divided into the preparation methods of graphene fibers and graphene fabrics. The preparation methods of graphene fiber mainly include surface coating method, melt spinning method, solution spinning method, blending spinning method and feeding method.…”

Graphene is the thinnest carbon nanomaterial and the basic unit of other carbon materials. It has been widely used in textiles. At the same time, various testing methods of graphene textiles have been extensively studied. This paper summarizes the preparation methods of graphene and graphene textiles, expounds the principle that textiles are endowed with various functionalities by graphene's unique physical structure, and realizes the research significance of graphene in functional textiles, intelligent textiles and industrial textiles (polymer cornerstone graphene). The preparation methods of graphene textiles are mainly divided into the preparation methods of graphene fibers and graphene fabrics. Through the analysis of various testing standards and research, transmission electron microscopy and Raman spectroscopy are mainly used in qualitative analysis of graphene materials in textiles, element analysis and thermogravimetric analysis are mainly used in quantitative analysis of graphene materials in textiles. All the above testing methods have certain limitations. Graphene textiles are developing rapidly and have great research potential. Effective testing methods are urgently needed.

In this article, we overview a very important type of natural fibre, namely, hemp fibre. We consider the exclusive structure, properties, modification, the composite or nanocomposite formation and exceptional application zones. Industrial hemp fibres have been commonly developed and possess high cellulose amounts. The long hemp fibres can be termed bast or flax fibres. Hemp fibres are eco-friendly, and have light weightiness and stiffness properties. Consequently, to enhance the use of hemp fibres at engineering level, research has focused on improving the mechanical or thermal and high-tech features of these fibres. In doing this, the surface modification or treatment of hemp fibres has been notably considered. The modified fibres have been found valuable for developing certain derived materials such as polymeric composites and nanocomposites in particular. Consequently, including hemp fibres as additives in composite or nanocomposite matrices has been explored for manufacturing high performance ecological, recyclable, biodegradable and sustainable materials. Application areas identified for the hemp and related composites or nanocomposites include the synchrotron and neutron scattering, water treatment aiming dye removal, automobiles, textiles and construction. However, there is insufficient literature on these technologically important fibres and ensuing materials. Comprehensive future efforts may better resolve the challenges regarding reproducibility and long life-cycle high-tech applications of hemp fibres.

“…Hemp has garnered great interest due to its biodegradability, low-cost, and fast-growing capability under mild and harsh weather conditions throughout the world (Dhondt 2020). Long hemp bast bers from hemp stalk have been used for a myriad of applications such as textiles, paper, and biodegradable composites (Wang et al 2020). Chemical composition of hemp bast consists of cellulose, lignin, hemicellulose, and gums including pectin, oil, wax, minerals (Liu et al 2017; Keiller et al 2021), and other non-cellulosic components.…”

Hemp bast fibers were degummed using combined microwave energy (MWE) and deep eutectic solvent (DES) to generate pure hemp cellulose fibers for potential textile applications. The properties of the obtained fibers were investigated and compared with those from the traditional alkali-based process using several analytical techniques. Results revealed that hemp fiber surface underwent dramatic structural disruption during the pretreatment, due to the removal of “gummy” compounds (i.e., lignin, pectin, oil, and wax) and amorphous cellulose. Ultraviolet (UV) protection factor (UPF) of DES-treated fibers with 1:20 fiber-DES ratio (i.e., 183.67) were significantly higher than those from the traditional alkali-treated (140.75) and untreated raw hemp fibers (127.47). The treated fibers also had higher thermal stability. Chemical composition analysis showed that the cellulose content in the treated fiber samples increased to 49.95% which was comparable with the cellulose content of the alkali-treated fibers (49.49%). The study demonstrates a potentially effective, less time-consuming, and environmentally sustainable protocol for manufacturing purified hemp cellulose fibers using combined MWE-DES treatment.
