For the first time, deoxyribonucleic acid (DNA) from herring sperm has been employed as a novel flame retardant system for enhancing thermal stability and properties of cotton fabrics. Indeed, DNA could be considered an intrinsically intumescent it contains three main components that are usually present in formulation, namely: phosphate groups, able to produce phosphoric acid, deoxyribose units acting carbon source blowing agents (upon heating (poly)saccharide dehydrates forming char...

Antimicrobial textiles can contribute to the fighting against antibiotic resistance pathogenic microorganisms. Polypyrrole is a conjugated polymer that exerts biocidal action thanks positive charges on its backbone chain produced during it synthesis. In this work, dispersions of stable polypyrrole nanoparticles were by chemical oxidative polymerization at room temperature in water. An ultrasound-assisted coating process was then used effectively treat polyester fabric with obtain an optimal...

Abstract This review is devoted to discuss the unique characteristics of multi-jet electrospinning technique, compared other spinning techniques, and its utilization in natural as well synthetic polymers. The advantages inadequacies current commercial chemical methods; namely wet spinning, melt dry are discussed. unconventional applications textile non-textile sectors reported. Special emphasis theory technology multijet applications. status electrospining future prospects outlined. Using...

It is urgent to expand the market of biodegradable alternatives oil-derived plastics owing (i) increasingly limited oil availability/accessibility, and (ii) dramatic impact traditional on aquatic life, food chain, all Earth ecosystems, ultimately, human health. Polyhydroxyalkanoates (PHAs) are promising polymers that can be obtained through microbial fermentation agro-industrial byproducts, e.g., milk cheese whey. Here, PHA-accumulating efficiency a mixed culture (MMC, derived from activated...

Keratin proteins extracted from wool fibers by sulfitolysis were electrospun for the production of active nanofiber membranes (NFMs). The keratin NFMs composited with nylon woven fabric improving their mechanical properties as a filtration material. prepared characterized in terms morphology, pore size, contact angle, and performance water air permeability. Experimental data showed that most investigated parameters affected electrospinning time: is, roughness rose increasing time, while...

ABSTRACT Polypyrrole is widely used as coating to produce electrically conductive textiles. Counter‐ions (i.e. doping agents) were embedded in polypyrrole improve electrical conductivity. Good performances are required for several applications, such microwave attenuation/electro‐magnetic interference shielding, heat generation, electro‐static discharge protection, sensing, and energy storage. In this work, a systematic study was carried out on the effects of agents cotton fabrics with thin...

Cheese whey results as by product of cheese or casein production in large amounts. Depending on the ceesemaking process, amount can rise to more than 6 times, a weight basis, produced.Cheese has considerable nutritional value and strong organic saline content, such pose serious disposal problems. The Chemical Oxygen Demand (COD) be high 100 kg m-3, so make impossible direct superficial water critical any biological treatment withoutprevious dilution. Many components have significant light...

Garment quality and preciousness depend on the type of textile fiber used in manufacturing. The softer rarer animal fiber, more expensive garment. cheapest clothes are made by mixing precious fibers such as cashmere with common ones sheep wool. To stop clothing counterfeit forgery, checking industries is pivotal. More general, law regulations require that declared composition a tissue meet some standards have to be assayed carefully expert operators. Microscopy techniques Scanning Electron...

The present work concerns the experimental evaluation of hazelnut shells as a low cost natural biosorbent. Adsorption direct azo dye Congo Red was performed within concentrations range 50-5000 mg/L. Hazelnut were employed organic support for Phanerochaete chrysosporium cultures to study best cultural medium composition MnP production. capability take macronutrients carbon and nitrogen from demonstrated. Cultures carried out with coming adsorption tests, showing that 43% adsorbed degraded.

Electrospinning is here used for the first time to prepare nanofibers including a host/guest complex in keratin/poly(ethylene oxide) matrix. The host lipid binding protein and guest an insoluble bactericidal molecule, irgasan, bound within internal cavity. obtained nanofibers, characterized by scanning electron microscopy, exhibit excellent antibacterial activity toward Gram positive negative bacteria, even with moderate protein/irgasan cargo. Solution NMR studies, employed provide molecular...

Cotton gauzes coated with chitosan have been tested as water filter for biological disinfection against Gram-positive bacteria. The present study develops the previous ones, aiming to stability evaluation of ultraviolet-cured coating cotton in order optimize amount applied substrate, lowering add-on percentage much possible: 10%, 5% and 2% wt were here considered. Antibacterial activity permanence this property after flow tested, showing good results, particular regards 10% gauze. Moreover,...

The method based on the ultra-performance liquid chromatography coupled with electrospray mass spectrometry (UPLC/ESI–MS) instrument was used for identification and quantification of most commercial Bovidae fibres (wool, cashmere yak). In present paper, this developed validated by authors confirmed many analyses of, known unknown, wool/cashmere/yak blends at different stages manufacture (fibres, slivers, yarns, fabrics, raw materials) treatments (dyed, depigmented, bleached, finished forms).

Abstract Chitosan was grafted on the surface of a cotton gauze (20, 50, and 100 mg chitosan g −1 cotton) to improve its stability in aqueous solutions. The adsorption hexavalent chromium ions from water evaluated determine, by means linear nonlinear models, kinetic isotherm process. kinetics pseudo second‐order, first‐order, isotherms type II were obtained, that is, monolayer nonporous adsorbents with physical present. most probable energy corresponded physisorption hydrogen bond...

Agro-industrial raw materials are becoming increasingly important in the field of biotechnological fermentation: they could be used as fermentation media, usually after proper pretreatment, and that way usefully exploited. Milk whey is an by-product dairy industry, nutrient-rich potentially a growth medium for production commercial products. Many processes can applied to whey, from using recombinant bacteria mixed consortium. The latter often requires careful monitoring. Monitoring control...
