This study aims to provide an overview of the latest research studies on use biopolymers in various textile processes, from spinning processes dyeing and finishing treatment, proposed as a possible solution reduce environmental impact industry. Recently, awareness polluting aspects production, based petroleum derivatives, has grown significantly. Environmental issues resulting greenhouse gas emissions, waste accumulation nature landfills, have pushed activities toward more sustainable, low-impact alternatives. Polymers derived renewable resources and/or with biodegradable characteristics were investigated follows: (i) constituent materials yarn view their superior ability be decomposed compared common synthetic petroleum-derived plastics, positive antibacterial activities, good breathability, mechanical properties; (ii) act biological catalysts; (iii) impart specific functional properties treated textiles; (iv) 3D printing technologies fabric surfaces replace traditionally pollutive dye-based inkjet printing; (v) implants for treatment dye-contaminated water. Finally, current projects led by well-known companies development new market are presented.

Abstract A dressing patch made of radially oriented poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) nanofibers was successfully manufactured with a modified electrospinning strategy. The as-electrospun PHBV nanofiber exhibited uniform and bead-free nanofibrous morphology innovative arrangement, which demonstrated to possess obviously improved mechanical property, increased surface hydrophilicity enhanced biological properties compared the control traditionally randomly pattern. Interestingly, it found that pattern could induce cell migration from periphery center along in rapid manner. To further improve biofunction patch, berberine (Beri, an isoquinoline alkaloid) two different concentrations were encapsulated into during electrospinning, present sustained drug release behavior for nearly one month. Importantly, addition Beri impart excellent anti-inflammatory property by significantly inhibiting secretion pro-inflammatory factors M1 macrophages, also showed additive influence on promoting proliferation human dermal fibroblasts (HDFs), as well growth E. coli, S. aureus C. albicans, Beri-free patch. In animal studies, electrospun loading high content accelerate healing process diabetic mouse full-thickness skin wound shortened time (100% closure rate after 18 days’ treatment) quality (improved collagen deposition, re-epithelialization neovascularization hair follicles). all, this study reported therapeutic strategy integrating physical cues multiple effective treatment hard-to-heal wounds.

Herbal drugs are safe and show significantly fewer side effects than their synthetic counterparts. Curcumin (an active ingredient primarily found in turmeric) shows therapeutic properties, but its commercial use as a medication is unrealized, because of doubts about potency. The literature reveals that electrospun nanofibers simplicity, efficiency, cost, reproducibility compared to other fabricating techniques. Forcespinning new technique minimizes limitations provides additional advantages electrospinning. Polymer-based nanofibers-whose lie stability, solubility, drug storage-overcome problems related delivery, like instability hydrophobicity. Curcumin-loaded polymer potency healing diabetic wounds vitro vivo. release profiles, cell viability, proliferation assays substantiate efficacy bone tissue repair delivery against lung, breast, colorectal, squamous, glioma, endometrial cancer cells.
