Comparative Study of a Drug Release from Textile to Skin Objective The achievement therapeutic dose the hydrocortisone acetate (HCr) for coetaneous affections by using: i) cyclodextrine derivative and ii) hydrogel, in systems fixing drug on textile material then releases it vitro towards dermis under action perspiration kit. Methods formation temporary deposit HCr cotton knitted fabric variants: 1) covalent grafting with monochloro triazinyl-beta-cyclodextrine (MCT-β-CD) complexation...
Knitted medical stockings destined for the treatment of venous diseases must fulfill proper functions during wear, with some restrictions criteria demanded by raw material and design parameters (including gradual compression size). As end use knitted implies a complex stresses applied in more than one direction, grab method was used an original way to assess fabric behavior three directions (wale, course bias), few seconds time delay between tests. This testing order determine capacity...
The study presents the preparation and characterization of new scaffolds based on bacterial cellulose keratin hydrogel which were seeded with adipose stem cells. was obtained by developing an Acetobacter xylinum culture visualized using SEM (scanning electron microscopy) elementally determined through EDAX (dispersive X-ray analysis) tests. Keratin species (β–keratose γ-keratose) extracted hydrolytic degradation from non-dyed human hair. SEM, conductometric titration tests performed for...
Abstract The concept of ‘environmental awareness’ has recently had a major impact on the textile industry and fashion world as well. In this context, use natural fibres development dyeing processes gradually became important goals industry. Of all fibres, hemp is considered to be one strongest most durable. A wide range extracts have been used for coloration dyeing. Dyes deriving from sources emerged an alternative synthetic dyes. Ecofriendly, nontoxic, sustainable renewable dyes pigments...
The Release of Tacrolimus from a Cotton Biomaterial to Dermis Abstract Objective: paper describes the creation delivery system for drug with high dimensions, as tacrolimus. Methods: achievement biomaterial manufactured alternative layers chitosan (CS) and sodium alginate (Alg) inclusion tacrolimus (Ta) between layers. By gradual dissolution layers, Ta is released. Results: On cotton fabric, it has been performed consists 10 CS Alg. can sustain then release according specific relase kinetics...
Tissue engineering as an interdisciplinary field implies fibrous polymers extracellular matrix biologic support. The paper is a review on basic lines of the answer textiles items at complex action. One carries out evolution usage following polysaccharide supports: cellulose, gellan, pullulan, chitosan, hyaluronic acid, well collagen protein representative for potential in matrix. presents advantages and drawbacks adjusted to online system new procedures available develop structure textile...
3-chloro-2-hydroxypropyl acrylate obtained by the esterification of epichlorohydrin with acrylic acid in presence zirconium silicate as a catalyst was used for grafting polyester fabric order to improve some its properties. The performed (NH 4 ) 2 S O 8 polymerization initiator. grafted samples were characterized Fourier transform infrared spectroscopy, scanning electron microscopy, and energy-dispersive X-ray spectroscopy analyses. effect on comfort indices (hygroscopicity vapor...
The work presents chemical procedures used to obtain a film or hydrogel after hydrolyze treatment of hair at the temperature 150oC and pressure 4.9 atm. In order hydrogel, this is followed by stage oxidation with hydrogen peroxide, reduction Na2S2O4 or, in another variant, peroxide NaOH alcoholic medium, form natrium cationic groups. protein chains sulphonic groups cations determine opposite electrostatic interactions, formation polymer loop that incorporate water. evaluation formed was...
The paper proposes a textile device for patients with large area burn wounds consisting of an assembly made up knitted backing layer, hydrogel, antibiotic content, as second layer and membrane controlled porosity located directly at the interface wound. knit is material support supporting clothing role, but also solution tank. hydrogel has keratin structure obtained from human hair advanced swelling capacity porosity. study use silver sulfadiazine (SSD), used in topical therapy wounds. work...
In this study, systematic adsorption tests were carried out using Co/gama-Al2O3 adsorbents of different compositions for removal Reactive Blue 19 dye from aqueous solutions. The adsorbent was characterized by scanning electron microscopy, X-Ray powder diffraction, diffuse reflectance UV-visible spectroscopy and EDX analysis. influences several parameters such as pH, concentration, time concentration on the capacity g-Al2O3 Co/g-Al2O3 investigated. obtained results indicate that is strongly...
The paper is the first communication on an exploratory study of use three compounds: bentonite, clinoptilolite and SBA-15 (Santa Barbara Amorphous). last component, SBA-15, cutting-edge result a chemical synthesis with perspectives for in biochemical field, but also as new controlled delivery system grafted fibrous textile component release drug from to dermis. Components are characterized terms specific surface area (m2/g), pore size sorption performance relation two antibacterial agents:...
