Due to its environmentally benign character, supercritical carbon dioxide (scCO2) is considered in green chemistry, as a substitute for organic solvents in chemical reactions. In this paper, an innovative approach for preparation of flame retardant cotton fabric was obtained by utilizing supercritical carbon dioxide with co-solvent. A novel phosphorusnitrogen containing piperazine derivative, t...

The structural characteristics, dimensional change after four washing cycles, non-creasing properties and air permeability of Swiss double piqué knitted fabrics from cotton/flax (70% cotton, 30% flax), PAN/flax PAN, flax) 100% flax yarns have been investigated. These fabric samples varying densities were produced on a 10 -gauge circular knitting machine. results investigation showed that the in...

BACKGROUND Bacteria from the hospital environment, including linens and curtains, are often responsible for hospital-associated infections. The aim of the present study was to evaluate the bactericidal effects of fabrics coated with the hydroxyapatite-binding silver/titanium dioxide ceramic nanocomposite "Earth-plus". METHODS Bactericidal activities of woven and nonwoven fabrics coated with E...

Spyn is a system for knitters to record, recall, and share information surrounding the process of handcraft. Using the yarn as a timeline of a knit's creation, Spyn allows knitters to associate digital annotations to knit yarn. The current prototype uses patterns of infrared ink printed on yarn in combination with computer vision techniques to associate locations in knit fabric with audio and v...

Magma transport through the Earth's crust occurs dominantly via sheet intrusions, such as dykes and cone-sheets, and is fundamental to crustal evolution, volcanic eruptions and geochemical element cycling. However, reliable methods to reconstruct flow direction in solidified sheet intrusions have proved elusive. Anisotropy of magnetic susceptibility (AMS) in magmatic sheets is often interpreted...

Enzymatic grafting of synthetic molecules onto lignins provides a mild and eco-friendly alternative for the functionalization of lignocellulosic materials. In this study, laccase-mediated grafting of octadecylamine (OA) onto lignin-rich jute fabrics was investigated for enhancing the surface hydrophobicity. First, the lignins in jute fabrics were isolated and analyzed in the macromolecular leve...

BACKGROUND Mattress and pillow encasings are recommended for patients allergic to dust mites. Many encasements block allergen and are vapor permeable but do not allow free passage of air through the material. Recently, breathable fabrics made from tightly woven synthetic fibers or nonwoven synthetics have been recommend as encasements. OBJECTIVE The purpose of this study was to develop a meth...

Cotton knitted fabrics were manufactured with different yarn types (conventional ring spun yarn and torque-free ring spun yarn) with different fibre types (combed cotton and combed Supima cotton) and yarn fineness (Ne30 and Ne40). These fabrics were then dyed with three types of dye (reactive, direct and sulphur dye) with three dye concentrations (0.1%, 1.0% and 5.0% on-weight of fabric (owf)) ...

This study attempts to investigate the pressure behavior of tubular knitted fabrics after a long period of time. For this purpose, two kinds of knitted fabric (plain and interlock) with various stitch lengths were chosen and the interfacial pressure and pressure reduction of fabrics after 48 hours were analyzed at different strain percents. The same tests were performed on the same specimens af...
