Article Abstract
In the context of escalating standards of living, the demand for healthy and multifunctional textiles is increasing. As a kind of cellulose macromolecular-based material, lyocell fiber has low carbon, is environmentally friendly, and demonstrates superb performance. The utilization of some Chinese herb dyes solves the pollution problem in the color and functionality construction of lyocell fabric by synthetic dyes and finishing agents. However, problems such as low dye utilization rate, light apparent color, and weak functionality of dyed fabrics remain, thus limiting the further application of the powerful combination of lyocell fabric and Chinese herb dyes. Here, a color and multifunction construction method of lyocell fabric with Coptis chinensis and 1,2,3,4-butanetetracarboxylic acid was proposed. Under the optimal color construction condition, the color depth increased remarkably, and the dye exhaustion rate of the modified fabric enhanced by 332.3 % compared with the unmodified one. The multifunction construction imparted outstanding fuzz and pilling inhibition, fibrillation resistance, and antiwrinkle performance for lyocell fabrics. Moreover, the dyed lyocell fabric exhibited considerable UV protective activity and antibacterial property against Staphylococcus aureus. This work provided an efficient color and multifunction construction technology for lyocell fabric with high value added.

The demand for safe, comfortable and sustainable materials in antibacterial textile production has led to the research of the new alternative materials and methods. This study focuses on the use of lyocell that is one of the promising regenerated cellulosic fiber as an alternative material and the application of the silver and zinc oxide nanoparticles by the combined pad-dry-cure and sol-gel methods to obtain durable performance. In addition, the dependence of the antibacterial properties of the coatings on the particle size and morphology of the nanocomposites and the performance of zinc oxide nanoparticles in the nanocomposite form with silver nanoparticles on lyocell fabrics have been comparatively and comprehensively investigated.

Cellulose-based functionalized fabrics are emerging as promising air purification filter materials. However, limitations such as poor moisture resistance, low strength, and heat sensitivity are challenging in the practical application of fine particulate matter filtration. Here, we developed a flexible and multifunctional lyocell/basalt fiber (LC/BF) filter fabric using a wet-laid process, avoiding the need for additional binders.

In this study, dodecyl(triphenyl)phosphonium bromide was successfully grafted onto cellulose molecules of bamboo pulp by ionic interactions, which was confirmed by infrared spectroscopy. This modification significantly improved the solubility and spinnability of the pulp. Subsequently, antimicrobial lyocell fibers were prepared from the modified pulp through a dry-jet wet spinning process.

Bast crops without narcotic ingredients are of particular significance to northern countries as seeds source, fibers, and dissolving pulp. In comparison to wood, hemp fibers contain a higher concentration of cellulose, whereas lignin is substantially lower. Winter maceration removes part of the cellulose satellites (pectins) and facilitate its further cooking.

Developing ultra-efficient fire-safety lyocell fabrics with high performances from biomass was the immense interest due to the sustainable and protective concerns. Herein, novel fully biomass coating of lyocell fabrics (Lyocell/PA-ZnG) was prepared using phytic acid (PA) and zinc gluconate (ZnG) via ion exchange reaction with water solvent. The ideal molecular regulation strategy endowed the Lyocell/PA-ZnG fabrics with rapid-formation thermal insulation residuals and excellent fire safety, which could pass the vertical burning test with the limiting oxygen index (LOI) of 28.
