Article Abstract

In this work, a multifunctional finishing agent named as PATFe was prepared from phytic acid (PA), tea polyphenols (TP), and Fe. The optimum weight ratio of PA to TP was determined by exploring the effect on flame retardant and tensile properties of viscose fabrics. Then, the effects of different concentrations of iron ions on the flame retardant and tensile properties of viscose fabrics were further investigated, and finally, multifunctional viscose fabrics, PATFe-9, were prepared. The system was investigated to confer the multifunctional effects on the flame retardant, bacteriostatic, and UV-resistant properties of viscose fabrics under the condition of lower weight gains (about 6.0 wt%). The limiting oxygen index of PATFe-9 reached 33.7 % with a weight gain of 6.1 wt%, and PATFe-9 had an inhibition effect against Staphylococcus aureus, and the ultraviolet protection factor value reached 67. It is worth noting that the breaking force retention rate of this system reached 100 %, which greatly improves the scope of use and added value of viscose fabrics.

The identification of cellulose fibers from different sources remains a significant challenge across various fields due to their complex structural composition and diverse applications. In this study, pyrolysis gas chromatography/high-resolution mass spectrometry (Py-GC/HRMS) was employed to identify cellulose fibers and fabrics utilizing a relative ratio approach based on pyrolyzate yield, with levoglucosan (LG) as the primary peak, furfural (FF) and 5-methyl-2(3H)-furanone (α-AL) as reference peaks. Initially, four cellulose fibers had large discrepancies in pyrolyzate yield relative ratios when pyrolyzed at 600°C.

Outdoor personal protective equipment (O-PPE) is vital for health and safety during activities, such as climbing and camping. However, achieving comfort in using O-PPE is challenging owing to subpar liquid management and rigid textures. In this study, a semiembedded HDPE/VIS microfibrous membrane was developed by hydroentangling a high-density polyethylene (HDPE) microfibrous web fabricated via flash spinning with a viscose (VIS) fibrous web created through carding.

Fungal biorefinery is a popular method for producing advanced fabrics but is currently limited to leather alternatives and similar by the sheet-based nature of most fungal materials. Biopolymers in the fungal cell wall, such as chitin and chitosan, are only soluble in harsh chemicals, making established extrusion-based yarn production systems expensive and hazardous. The Japanese art of Shifu is used to produce fungal chitin-β-glucan yarns of varying linear density from engineered fungal sheets, enabling the production of yarns.
