Comparative Evaluation of Physical and Structural Properties of Water Retted and Non-retted Flax Fibers
Flax stems of Modran variety were subjected to water retting under laboratory conditions and its physical properties were compared with non-retted fibers. Physical properties including percentage of impurities, weighted average length, linear density, tenacity and elongation were analyzed and the results were compared. The analysis of retted and non-retted flax fibers showed that retting is the...
متن کاملEffect of Impregnated Inorganic Nanoparticles on the Properties of the Kenaf Bast Fibers
The objective of this research was to evaluate the properties of the chemically retted kenaf bast fiber impregnated with the inorganic nanoparticles. High quality kenaf bast fibers were obtained from a chemical retting process. An in situ inorganic nanoparticle impregnation (INI) process was used to introduce the CaCO3 nanoparticles into the retted kenaf bast fibers. It was found that some of t...
متن کاملA Chemical Process for Preparing Cellulosic Fibers Hierarchically from Kenaf Bast Fibers
The objective of this research was to evaluate an all-chemical process to prepare nano-scale to macro-scale cellulosic fibers from kenaf bast fibers, for polymer composite reinforcement. The procedure used in this all-chemical process included alkaline retting to obtain single cellulosic retted fiber, bleaching treatment to obtain delignified bleached fiber, and acidic hydrolysis to obtain both...
متن کاملQuality of chemically modified hemp fibers.
Hemp fibers are very interesting natural material for textile and technical applications now. Applying hemp fibers to the apparel sector requires improved quality fibers. In this paper, hemp fibers were modified with sodium hydroxide solutions (5% and 18% w/v), at room and boiling temperature, for different periods of time, and both under tension and slack, in order to partially extract noncell...
متن کاملChemical and physical characterization of water- and dew-retted flax fibers
The composition of dew-retted and water-retted flax fibers were evaluated by chemical and mass spectral analyses to determine their chemical differences. Phenolics, waxes, cutin, and carbohydrates were determined by gas liquid chromatography. Water-retted fibers contained more residual wax and lower arabinose content than the dew-retted and were finer and stronger. Pyrolysis mass spectrometric ...
