Both ultraviolet (UV) and infrared (IR) light have negative impact on the human health. With this background it is main aim of current research to realize a textile material which able protect against both UV IR light. For research, regenerated cellulosic fibers from Lyocell process are used modified. Main analytical investigations done by photo-spectroscopy in arrangement diffuse transmission ...

Spinning of cellulosic fibers requires the prior dissolution cellulose. 3-Alkyl-1-methylimidazolium ionic liquids have proven to be suitable solvents for that purpose, but degradation cellulose in spinning dope can severe. Suitable stabilizers are therefore required prevent degradation, do not adversely affect spinnability or long-term yellowing behavior fibers. A group twelve renewables-based ...

Flax fibers were ground with a ball-mill and four fractions with different size ranges were collected by sieving. These were tested for water sorption, degree of polymerization (DP), copper number, hydroxyl number and analyzed by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM) and inverse gas chromatography (IGC). Significant differences were ...

In this study, waste flax fibers with different levels of cellulosic and noncellulosic components were obtained by oxidative alkali treatments used to assess the influence fiber’s structural chemical properties on biosorption lead ions. Scanning electron microscopy was for characterization fibers’ surface morphology, while physicochemical determined streaming potential method, Fourier transform...

application of cellulosic fibers and minerals of deinked waste paper sludge has a great impression on utilization and characteristics of final product. this study was designed to produce use gypsum-fiber board from the dip sludge. the gypsum: sludge ratio was considered as 100:0, 90:10, 80:20, 70:30 and 60:40. two types of gypsum boards were prepared with fixed 12 mm thickness and cold pressing...

Jute is one of the available and cheap cellulosic fibers that can be printed used instead other materials may relatively high in price. bio-degradable raw therefore does not cause harm to environment along with advantages because its many advantages, it called golden fiber. Textile printing practice applying color distinct patterns or designs sharp outlines. Inappropriately fibers, tied fiber, ...

The application of Fourier Transform (FT) spectroscopy instruments has broadened the knowledge and capabilities of textile researchers to study a host of projects including surface modifications of cotton fibers to impart flame retardant capabilities, monitoring aging effects on ancient cellulosic artifacts (Kavkler et al., 2011; Lojewski et al., 2010), determining the amount of dye fixation to...

The purpose of this work was to prepare chitosan–essential oil microcapsules using the simple coacervation method and graft them onto cellulosic fibers obtain bio functional textile. morphology characterized by optical microscopy. 2D dimethyloldihydroxyethylene urea resin (DMDHEU) used as a binding agent on surface fibers. Scanning Electron Microscopy (SEM) photographs Attenuated Total Reflecta...

Cellulosic fibers from date palm are among the most promising lignocellulose feedstock for biorefinery purposes. The world production is between 1.9 and 2.4 million t/year. Initially, a pretreatment with dilute-sulphuric acid of these was performed using response surface methodology, temperature process time as factors. aim to produce bioethanol young old palm, Phoenix dactylifera L. Optimal th...
