A preliminary study of kenaf fiber bundles and their composite cells

Only the bark of the kenaf stalk is fibrous. It has fiber bundles bound by lignin and other natural binders. The fiber bundles have single kenaf fibers of varying lengths and widths. Fiber dimensions are critical for textile preparation, nonwoven processing, and pulp and papermaking. This study examined the characteristics of single kenaf..

Computer-Based Plant Monitoring Systems.

Mathematical models of cotton crops may replace conventional visual observation to evaluated crop condition. Visual assessments do not provide quantitative data. Different models emphasize different plant characteristics, but most use plant stand, plant h

Covalently Bonding a Dye Molecule to Polyurethane.

Colored polyurethane (PU) leather frequently consists of a nonwoven fabric coated with a mixture of pigment and PU resin. The color of PU leather, however, is dull and migrates easily. Researcher grafted PU copolymers with a (2-hydroxyethyl)ethylene diami

Biodegradable composite Materials from Cellulosic Fibres and Derivatives.

Increasing pressures to achieve sustainable development and resourcing protection system have increased the demand for natural and organic raw materials in a variety of end uses. Biodegradable composite materials based on cellulosic fibers from such sourc

Determination of the Dynamic Modulus of Continuous Filaments of Polyvinyl Alcohol.

Experiments used ultrasonic techniques to measure the dynamic modulus of continuous filaments of polvinyl alcohol. Important parameters were the speed and modulus of the ultrasonic waves. The experiments used the Dr. Steinkamp Ultrasonic Tester VP V to maintain Solvron-SX filaments in a continuous ultrasonic field during load and relaxati..

Basofil Fiber: A Melamine-Based Fiber for High Temperature Applications.

BASF Corporatation constructed a Basofil heat and flame resistant fiber manufacturing plant near Asheville, North Carolina, in 1996. It is the first Basofil facility in the United States. Basofil manufacture uses melamine resins, which feature high wear p

Lyocell -- From Niche to Mainstream.

Lyocell is a 100 percent natural cellulosic fiber derived from wood pulp using a solvent spinning process. Courtaulds Fibers and Lenzing each manufacture lyocell fibers. Lyocell features high strength in both the wet and dry states, very high modulus, low shrinkage, and dyeability using cellulosic fiber dyes and dyeing methods. During pro..

Introduction of New Cellulosic Fibres and Environmental Protection.

To meet current environmental standards, Lenzing offers technology to improve existing viscose plants and a new lyocell technology. Lenzing's pulp and viscose fiber manufacturing facilities use biological wastewater purification plants, an efficient flue gas desulfurization recovery boiler, and sulfosorbon systems for carbon disulfide and..

Micro Fibres from Lenzing.

Lenzing uses renewable raw materials and an environmentally sensitive process to manufacture its Micro Modal ultrafine fibers, which are finer than silk. Ten thousand meters weigh only 1 gram. Its fineness and regularity allow the manufacture of light fabrics noted for softness, suppleness, and silk-like appearance. Micro Modal fibes blen..

Multicomponent-and Microfibers.

The two groups of bicomponent or composite fibers are conjugated fibers with continuous structure along the fiber axis, and polymer blended fibers that always lack a continuous structure. Conjugated fibers include self crimping, thermal bonding, electroconductive, antistatic, light conductive, water absorbent, and splittable fibers. Basic..
