In the past two decades, a growing body of research regarding utilization natural bacterial pigments or dyes for textile dyeing has emerged. Bacterial are secondary metabolites that usually have bright colors and some special properties (e.g., antimicrobial, antioxidative, UV protective etc.). addition to their high production yield, these led scientists develop methods utilizing in dyeing. This study presents current state this field research, with focus on potential different types...
Abstract Variations on the processing conditions of conventional methods for polymeric film preparation may allow tuning certain properties. In this work, different casting surfaces and humidity are presented as variables to consider cellulose acetate (CA) using solution method. Specifically, borosilicate glass, soda-lime glass Teflon (PTFE) dishes have been used their influence various properties CA films assessed. The smooth, while PTFE surface has a pattern constituted by concentric...
Solution blow spinning (SBS), a processing method alternative to electrospinning, where pressured air is used instead of an electric field, was in this work for the preparation cellulose acetate (CA) materials. The sequential use SBS produce double-layered film also investigated. Mixtures acetone with acetic acid or N,N-dimethylformamide (DMF) were studied as systems polymer solution preparation. type produced material (flat multi-structured membranes constituted from submicrometric fibers...
Cellulose acetate (CA) nanofibers are prepared using solution blow co-spinning (SBS) with poly(ethylene oxide) (PEO). The pure CA membranes obtained by washing water-soluble PEO from the fibrous CA-PEO blend. Nanofibrous characterized optical and scanning electron microscopy (SEM), differential calorimetry (DSC), infrared spectroscopy (ATR-FTIR), surface zeta potential measurements. Thermal transitions DSC ATR-FTIR spectra analysis were used to confirm removal of PEO. Although characteristic...
In this work, the preparation and characterization of composites from cellulose acetate (CA)–poly(ethylene oxide) (PEO) nanofibers (NFs) with incorporated zinc oxide nanoparticles (ZnO-NPs) using solution blow spinning (SBS) is reported. CA–PEO were produced by that contained a higher CA-to-PEO ratio lower (equal) ratio. Nanoparticles added to comprise 2.5% 5% solution, calculated on weight polymers. To have better control SBS processing conditions, suspensions carried out, which reveals...
Cellulose acetate (CA), a very promising derivative of cellulose, has come into the focus research due to its highly desired good film-forming ability for food packaging applications. Frequently, this is used in combination with other compounds (polymers, nanoparticles) order obtain active materials. Here, we report preparation thin films made cellulose loaded chitosan (CS) using solution blow spinning (SBS) method. Films are prepared by SBS processing polymers mixture solution, considering...
Apart from structure and composition, morphology plays a significant role in influencing the performance of materials terms both bulk surface behavior. In this work, polylactic acid (PLA) constituted by submicrometric fibers is prepared. Using modified electrospinning (ES) device to carry out solution blow spinning (SBS), fibrillar modified, with aim induce variations properties material. The modification ES consists incorporation source pressurized gas (air) 3D-printed nozzle our own...
Materials from biological origin composed by renewable carbon facilitate the transition linear carbon-intensive economy to a sustainable circular economy. Accordingly, we use solution blow spinning develop fully biobased cellulose acetate films and nanofiber mats reinforced with fungal chitin nanofibrils (ChNFs), an emerging bio-colloid lower footprint compared crustacean-derived nanochitin. This study incorporates ChNFs into processes for first time. ChNF addition reduces film surface...
We find that nitrogen plasma treatment of micro/nanofibrillated cellulose films increases wettability the surface by both liquid polar water and nonpolar hexadecane. The increased wetting effect is more pronounced in case liquid, favouring use treated as substrates for a range inkjet printing including organic-based polar-solvent inks. were formed from aqueous suspensions progressively enzymatic pretreated wood-free fibres, resulting removal amorphous species producing novel nanocellulose...
Cotton yarn was oxidized using the various concentrations and pH of potassium permanganate solutions, in order to investigate influence oxidation parameters on chemical, mechanical sorption properties cotton. The progress monitored through weight loss, carbonyl carboxyl group content, tensile strength, moisture sorption, crystallinity change, surface charge morphology modified samples. groups were introduced into cotton up 0.3 mmol·g−1, while loss 5%. samples, compared with untreated cotton,...
This study aimed to obtain functional viscose textiles based on chitosan coatings with improved antibacterial properties and washing durability. For that reason, before functionalization chitosan/zinc nanoparticles (NCH+Zn), the fabric was modified by nonthermal gas plasma of dielectric barrier discharge (DBD) introduce into its structure groups suitable for attachment NCH+Zn. NCH+Zn were characterized measurements hydrodynamic diameter zeta potential AFM. DBD-plasma-modified...
In this work, materials with potential biomedical applications constituted by fibrous poly(ethylene oxide), PEO, are prepared solution blow spinning (SBS). The SBS setup has a cylindrical collector for which the rotational speed and size varied to study its effect on final morphology of materials. is inspected using field emission scanning electron microscopy studied image analysis. As result, many doubts were generated because use different methods analysis, therefore simpler more...
