Latron - A Biodegradable Fiber, Its Development and Applications.
Lactron, a biodegradable manmade fiber manufactured from melt extruded polylactic acid (PLA), has a density of 1.27 grams per cubic centimeter, tensile strength of 4.5-5.5 grams per denier, elongation of 30 percent, and Young's modulus of 400-600. It has sufficient tenacity and durability for common apparel and nonapparel applications. Co..
Study of the Skin-Core Structure of Lyocell Staple Fibers.
Researchers used optical microscopy and scanning electron microscopy to examine the skin-core structure of lyocell staple fibers. Photomicrographs of damaged lyocell staple fibers provided information concerning skin-core structure, and characteristics of the lyocell fiber core, fiber surface, macrofibrils, and fibrillation. The core comp..
Physics and Chemistry of Wool Yellowing
An overview of recent research on the physics and chemistry of wool yellowing and the types of chromophores present in wool provides a perspective on the chemical basis of wool color. Topics include adventitious discoloration, bleaching, photochemistry of key amino acids in wool, analytical methods used to study wool yellowing, extraction..
Chemical Composition of Jute and Its Estimation
Researchers studied the basic chemical composition of jute using estimation techniques. Experiments estimated the levels of holocellulose; alpha cellulose; hemicellulose; lignin, including hemilignin and glycolignin; fats and waxes; pectin; protein; mineral matter; metal ions; coloring matter consisting of xanthophyll, carotene, and tanni..
Use of Jute in the Pulping Sector by Biological Agent.
Utilizing jute plant stems for the manufacture of paper and boards by conventional methods involves digestion of the stem fibers with caustic soda, sodium sulfide, or sodium carbonate in open conditions or under pressure. Because these methods consume chemicals and energy and contribute to pollution, researchers have developed biopulping ..
Pienapple Fibre Spun on Worsted and Cotton Systems.
Researchers at the China Textile University in Shanghai processed chemically treated pineapple leaf fibers on both worsted and cotton spinning machines. Pineapple fiber properties are similar to those of jute and flax, but pineapple features a higher level of noncellulose material, so that it is coarser and has lower elongation. The stron..
