Lyocell fiber has emerged as an important class of regenerated cellulose that is produced based on the N-methyl morpholine-N-oxide (NMMO) dissolution method, and it has unique properties compared to viscose fiber. The NMMO technology provides a simple, resource-conserving, and environmentally friendly method for producing regenerated cellulose fiber. In this paper, the manufacturing process, environmental impact, and product quality of lyocell fiber are reviewed and compared with those of the conventional viscose fiber.

Abstract A new type of regenerated cellulose fiber can be made from bamboo cellulose by the Lyocell process. In this paper, the morphology and crystal structure of the bamboo Lyocell fiber was investigated by optical microscopy, scanning electron microscopy, and wide angle X-ray diffractometry. Moreover, the mechanical properties, fibrillation behavior, moisture adsorption property, negative ion effect, and antibacterial capability of the bamboo Lyocell fiber were studied. The results showed that the bamboo Lyocell fiber proved to be similar to the structure and properties of wood Lyocell fiber, such as smooth surface, circular cross-section, high crystallinity, high tensile strength, low elongation at break, good moisture adsorption property, and easy fibrillation. Furthermore, the bamboo Lyocell fiber surpassed wood Lyocell fiber concerning negative ion effect and antibacterial property.

Regenerated Cellulose Fiber

Traditional regenerated cellulose fiber (viscose or viscose fiber) had a poor wet breaking strength and wet modulus, which to some extent limited the application of the fiber. Hollow viscose was difficult to get for its instability during the cellulose regenerating process. This paper introduced one kind of new spinning method for hollow viscose through a spinneret of concentric shaft structure using HWM technology. The hollow viscose fiber produced in this experiment had a big crystalline structure and an excellent fibril orientation which gifted the fiber a good mechanical performance even under wet circumstances. The fiber had a bright future in textile application as one component of blending fabrics.

Using the corncob residue as a new cheaper source material for Lyocell spinning technology. Chemical properties of the corncob residue after extraction of hemicellulose and lignin were investigated in this paper. It was found that the main composition of corncob residue is cellulose, accompanied by slight hemicellulose and very tiny amount of spinning insoluble components. Compared to wood pulp, corncob residue has a similar number-average molecular weight, a slightly larger weight-average molecular weight, a lower peak-relative molecular weight, and a larger polydispersity. All those properties suggest that this kind of corncob residue has big potential to be used as spinning material for regenerated cellulose fiber. A new type corncob residue made fiber was produced, using the Lyocell spinning technology. Mechanical properties of the corncob residue fiber were analyzed. The corncob residue fiber has a tensile strength value between that of viscose fiber and Lyocell fiber, indicating its good application prospects. However, the corncob residue fiber has a high crystallinity and the orientation value with large fiber linear density, suggesting that the spinning technology needs to be further improved.

Abstract The performance of a fiber-reinforced polymer composite depends not only on the properties of the fiber and matrix polymer but also on the interfacial properties. Nanoindentation and numerical simulation in our previous study revealed that the transition zone of the interfacial region between the regenerated cellulose fiber (lyocell fiber) and polypropylene (PP) was less than 1 μm. Interfacial zone was modified with maleic anhydride-grafted PP (MA-g-PP) and γ-amino propyl trimethoxy silane (γ-APS). In the present study, the interfacial zone is investigated by means of contrast imaging techniques based on phase and thermal conductivity in the context of atomic force microscopy. According to the obtained images, the widths of the interfacial zone modified with MA-g-PP were approximately 113–128 nm and modification with MA-g-PP and γ-APS led to an interfacial zone of 109–173 nm.

Regenerated cellulose fiber is the most widely-used and most variety of cellulose fiber. Five categories and ten kinds of fibers such as lyocell fiber, modal fiber, bamboo pulp fiber, sheng-bast fiber, Outlast viscose fiber were chosen as the research object. The strength property and elasticity of fibers in dry and wet state were tested and analysis. The comprehensive performances of fabrics were studied and mechanical properties of the fibers were listed in the order from good to bad by grey clustering analysis. The results show lyocell G100 and lyocell LF have better comprehensive mechanical properties ,while other new regenerated cellulose fibers’ comprehensive mechanical properties are general. Among these fibers modal fiber’s comprehensive mechanical properties are slightly better than sheng-bast fibers’ and bamboo pulp fibers’. Modal fiber, sheng-bast fiber and Bamboo pulp fiber have no significantly poor single parameter and all of them have better comprehensive mechanical properties than various viscose fibers. Outlast viscose in which has been added phase change materials sensitive to temperature by Microcapsule techniques fundamentally keeps similar comprehensive mechanical properties with other regenerated cellulose fibers,but its properties decline slightly .

The cellulose film was prepared from regenerated cellulose fiber residue by dissolving the cellulose in sodium hydroxide solution at low temperature (-15 °C). The properties of the prepared film were investigated by tensile testing, Scanning Electron Microscope (SEM), X-ray Diffractometer (XRD) and also swelling ratio. Curcumin was added into the film with three different concentrations. The color strength of the curcumin-added film was evaluated and the color change of this film in different pH was also reported.

Denim is no more “work wear’’ in the present era. More than a need, it is a fashion commodity for every age group, specifically for youth. Garments with multiple permutations and combinations of denim fabric variables like fibers, yarns, and Lycra % and weaving techniques are available with differing garment design statements, but the comfort aspect is slightly ignored. To cater for the masses living in hot and humid areas, a denim fabric is being projected with varying garment constructional parameters. Regenerated cellulose-based fibers/yarns are considered as ecofriendly, cool, soft, fairly strong, and durable among other man-made and natural fiber-based yarns. The present study is an attempt to develop comfortable denim clothing using regenerated cellulose fiber derivatives, maintaining its traditional rustic look for tropical regions. Fabric performance evaluation methods were used to ascertain the performance of the newly developed clothing.
