Enhancing some functional properties of viscose fabric

Carbohydrate Polymers, 2013
To enhance the functional properties of viscose fabrics, Tinosan(®) CEL (TC), Ag, and TiO(2) nano-particles were incorporated as functional additives in different easy care finishing formulations alone and in admixtures. Results indicated that padding viscose fabrics in finishing bath containing 10 g/l TC and 60 g/l dimethyloldihydroxyethylene urea ...

Viscosity of fluoride glass fibers for fused component fabrication

Applied Optics, 2022
Fluoride glasses show great promise for mid-IR fiber-based applications. Their brittleness and low glass transition temperature have thus far been obstacles towards obtaining low-loss fused components. Here, we suggest a simple method to measure glass viscosity over a range of process temperatures of interest for fused coupler ...

Flame‐retardant viscose–polyester fabrics

Journal of Applied Polymer Science, 1986
AbstractFor many purposes the natural‐synthetic fiber‐blend fabrics are more suitable than pure natural or synthetic products. It is often possible to obtain a maximum in clothing and textile technical properties by compensating the defects of one fiber by using an other totally different fiber.

Wound dressing based on nonwoven viscose fabrics

Carbohydrate Polymers, 2012
Nonwoven viscose fabric was treated with chitosan/polyvinyl alcohol (PVA) using pad-dry method, using different concentrations of chitosan and PVA. Increasing the amount of PVA leads to increasing of air permeability. Water permeability increased by increasing the amount of PVA to 2 ml (10% solution) then decreased by any increase of the quantity of ...

Fabrication of oxidized sodium carboxymethylcellulose from viscose fibers and their viscosity behaviors

Fibers and Polymers, 2013
The oxidized sodium carboxymethylcellulose (O-CMC) fibers have been successfully synthesized via the oxidation-etherification method. Subsequently, the O-CMC fibers are characterized by Fourier transform infrared (FT-IR), 13C nuclear magnetic resonance (13C-NMR) and X-ray diffraction (XRD).

Imparting permanent antimicrobial activity onto viscose and acrylic fabrics

International Journal of Biological Macromolecules, 2012
Viscose and acrylic fabrics were aminated to enhance metal chelation of Cu, Zn and Ni for the purpose of imparting fabrics antimicrobial activity against Escherichia coli and Staphylococcus aureus. Fabrics were firstly epoxidized using epichlorohydrin prior amination. Optimization of the reaction conditions, e.g., temperature, medium pH, amine type and

Fabrication of Antimicrobial Viscose Materials with Antiadhesive Properties

Fibre Chemistry, 2004
A higher level of oil- and water-repellent properties is attained as a result of successive treatment of viscous material with polyhexamethyleneguanidine hydrochloride [PHMG(X)] and phosphorus-containing polymer with latex. It was found that desorption of PHMG(X) is more effective when the amount of applied fluoropolymer on the surface of the fibre ...
