In this study, a novel type of high-strength regenerated cellulose composite fiber reinforced with cellulose nanofibrils (CNFs) and nanosilica (nano-SiO2) was prepared. Adding 1% CNF and 1% nano-SiO2 to pulp/AMIMCl improved the tensile strength of the composite cellulose by 47.46%. The surface of the regenerated fiber exhibited a scaly structure with pores, which could be reduced by adding CNF and nano-SiO2, resulting in the enhancement of physical strength of regenerated fibers. The cellulose/AMIMCl mixture with or without the addition of nanomaterials performed as shear thinning fluids, also known as “pseudoplastic” fluids. Increasing the temperature lowered the viscosity. The yield stress and viscosity sequences were as follows: RCF-CNF2 > RCF-CNF2-SiO22 > RCF-SiO22 > RCF > RCF-CNF1-SiO21. Under the same oscillation frequency, G’ and G” decreased with the increase of temperature, which indicated a reduction in viscoelasticity. A preferred cellulose/AMIMCl mixture was obtained with the addition of 1% CNF and 1% nano-SiO2, by which the viscosity and shear stress of the adhesive were significantly reduced at 80 °C.

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.

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.

The flexible SERS substrate were prepared base on regenerated cellulose fibers, in which the Au nanoparticles were controllably assembled on fiber through electrostatic interaction. The cellulose fiber was regenerated from waste paper through the dry-jet wet spinning method, an eco-friendly and convenient approach by using ionic liquid. The Au NPs could be controllably distributed on the surface of fiber by adjusting the conditions during the process of assembling. Finite-difference time-domain theoretical simulations verified the intense local electromagnetic fields of plasmonic composites. The flexible SERS fibers show excellent SERS sensitivity and adsorption capability. A typical Raman probe molecule, 4-Mercaptobenzoicacid (4-MBA), was used to verify the SERS cellulose fibers, the sensitivity could achieve to 10−9 M. The flexible SERS fibers were successfully used for identifying dimetridazole (DMZ) from aqueous solution. Furthermore, the flexible SERS fibers were used for detecting DMZ from the surface of fish by simply swabbing process. It is clear that the fabricated plasmonic composite can be applied for the identifying toxins and chemicals.

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 .

A new flame-retardant protein viscose fiber with safely wearing performance has been prepared through blending protein solution, flame retardant (hexaphenoxycyclotriphosphazene) and viscose spinning solution, in which wool protein was used and added to spinning solution on the basis of 16% flame retardant, and the properties of the fiber were investigated. The product has more compact structure inside the fiber and evenly scattered small pores on the surface. Flame-retardant protein viscose fiber can reach the flame-retardant standard both before and after 30 times wash test, and the mechanical strength of the fiber was also improved. The introduction of hexaphenoxycyclotriphosphazene lowered the primary decomposition temperature of viscose fiber, reduced its weight loss. The flame-retardancy of the fiber can be improved by the introduction of protein. In thermal processes, the major product of thermal decomposition was CO2, no hazardous and noxious gases were released. Due to the introduction of protein, moisture regain of the fiber is a little lower than that of viscose fiber, but higher than flame-retardant viscose fiber. Warmth retention property was also improved. Friction coefficient of the product is lower than that of flame-retardant viscose fiber. Bulking intensity was increased, which is better than that of viscose fiber.

The thermokinetics of the action of water, methanol, ethanol, n-propanol, n-butanol, acetic acid, and concentrated aqueous solutions of NaOH and ethylenediamine on native, mercerized, and regenerated cellulose has been studied by a microcalorimetric method. The penetration rate depends, first of all, on the structure of accessible regions, the dimensions of the penetrant molecule, and the penetrant reaction with hydroxyl groups. If the penetrant molecule has suitable dimensions, the penetration becomes a slow process, making it possible to follow the structural differences in the accessible region even in fibers of the same type. Such liquids are ethanol and acetic acid for native cellulose, methanol and concentrated solutions of ethylenediamine for regenerated cellulose, and concentrated solutions of NaOH (37.5% and 41.5%) for all kinds of cellulose. The accessible phase in cellulose has a discontinuous structure within the spacing of structural elements in the intermicrofibrillar and intermolecular regions. This discontinuity may sometimes be the cause of composite thermograms. Similar thermograms with two characteristic peaks are obtained for some viscose fibers which have at least a two-zone structure of the skin-core type. The intermolecular distances in the accessible regions of microfibrils seem to be of the same order of magnitude as that of the ethanol molecule with reference to native cellulose and the methanol molecule, to regenerated cellulose. The structure of these regions readily undergoes specific changes under the influence of various treatments. This is reflected in the shape of thermograms and magnitude of integral heat effects. The results indicate that the microcalorimetric measurements of the penetration thermokinetics may be a useful tool for investigating the accessible regions

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.
