A New Cellulosic Fibre--Tencel.

An introduction to Tencel, a fiber produced by an environmentally friendly solvent spinning process that utilizes the direct dissolution of cellulose in an organic solvent, describes the formation, properties, and applications of the fiber. Tencel features high strength and good tensile characteristics that facilitate its use in blends wi..

Realization of the Strength of Carbon Fibres in Microplastics.

Research on the mechanisms involved in the realization of strength in microplastics reinforced with carbon fibers prepared test samples by fiber impregnation with epoxy-phenol binder under tension. The research measured the mechanical properties of both the carbon fibers and the microplastics reinforced with carbon fibers on various Instr..

Structural Changes in Thermal Stabilization of Polyacrylonitrile Fibre

Research on the structural transformations that occur during the thermal stabilization of polyacrylonitrile fiber (PAN) prepared samples with the salt method. X-ray diffraction and infrared polarization spectroscopy evaluated changes in the orientation of PAN fiber during oxidation. X-ray diffraction was optimal for the evaluation of the ..

High-Tenacity and High-Modulus Polyacrylonitrile Fibres

Wet extrusion produced poly(acrylonitrile-Methyl methacrylate) fiberas with intrinsic viscosities ranging from 2.24-4.10 deciliter per gram. The exact values of intrinsic and dynamic viscosity depended on the concentration of the spinning solution, which was varied from 15-17.15 percent. Breaking tension and the Young's modulus of the fib..

The Influence of Skin Wrinkle on Some Attributes of Skin and Wool.

Researchers compared the differences in wool grown on the folds and wrinkles at the neck, midside, and thigh of sheep with wool grown on adjacent nonwrinkled skin. Ten selected merino wethers from a medium wool merino flock exhibited extreme fold and wrinkle development of the skin. Results indicated that wool grown on the folds and wrink..

Temperature Dependence of Fiber Cellulose Biosynthesis: Impact on Fiber Maturity and Strength.

Researchers monitored the cellular synthesis of different cultivars of Gossypium hirsutum in response to cool temperatures. They monitored cellulose synthesis and respiration at 34, 28, 22, and 15 degrees centigrade and evaluated the cellulose synthesis ability of the cultivars after rewarming from 15 degrees centigrade. Yugoslavian and P..

Effect of Senomes on the Wax Content of Cotton Fibers

Researchers studied the effect of xenomes on the wax content of cotton fibers. Researchers applied xenomes (fenvalerate and emthyl alcohol) used to manage insecticide induced upsurgence of plant lice Aphis gossypii to cotton variety LRA 5166 once every ten days, beginning 50 days after germination of the cotton crop. Researchers made five..

Identification of trash particles using digital image processing

A system is described which has been developed for the discriminatory reproducible analysis of trash particles. The system analyses trash particle content while discriminating between different classes of trash. This can be used to determine the composition of trash in bale samples, thus enabling assessment of the cleaning effort required..

The Challenge of Eco-Friendly Textiles Exports to Germany and Europe.

Prompted by consumer demand for environmentally safe products, Germany is banning the manufacture and import of any textile product containing azo dyes. Current environmental protection regulations for the textile industry cover all sectors, including cotton cultivation, yarn spinning, fabric weaving, dyeing, finishing, and refining the f..

Beyond Caprolactam -- Calculating Air Emissions from Yarn Heatsetting and Dyeing Processes.

For the carpet industry, the most relevant new component of the Clean Air Act Amendments (CAAA) is Title V. which initiates a national operating permit program for stationary air pollution sources. Stationary sources at carpet and yarn plants include boilers, heat setting and carpet backing machines, carpet and batch dyeing equipment, pol..
