Wellman Launches New Fiber.

Wellman Incorporated's Sensura manmade fiber is colorfast and shrink resistant. The chemical structure of the fiber, which will compete for market share with cotton, remains undisclosed. Sensura fiber dries twice as fast as cotton fiber. Sensura fabrics are soft and drapeable and wick perspiration through the microclimate between the skin..

Special Fibres for the Millennium.

Chameleon fibers change color, hue, depth of shade, or optical transparency in the presence of an electrical or magnetic field. Markets for such fibers-which incorporate molecules and oligomers that change their absorption or reflection of electromagnetic radiation in the infrared, visible, and ultraviolet spectra-include floor coverings,..

Smart Fibers - Application and Development Trends.

Smart fibers offer unique properties that enhance the performance of end products. Potential applications for smart fibers include automobile tires with improved fatique resistance and suspension systems ; airplanes manufactured with high performance carbon/aramid materials ; personal safety products that are inserted into apparel, cushio..

Cotton in nonwovens applictions

For suppliers to nonwovens, the decrease in cotton prices is a help in the constant need to compete with low-priced synthetics. The use of cotton is being promoted worldwide, although the single largest buyer of us exports this year is Mexico. The health and personal care market still has great potential for increased use of cotton fibers

Outlook for US cotton 1999

This article is a compilation of excerpts than the National Cotton Council's annual report on the outlook of US cotton. It begins by recapping events of '98, which saw falling farm incomes, poor weather conditions and disappointing yields. A strong dollar and cheap imports compounded problems for the mills, and the US trade deficit in tex..

The sozes and number of neps at different stages of cotton procesing: Some observations

Samples sent by mills to the South India Textile Research Association (SITRA) were tested using Uster AFIS or Lenzing FILE to assess the neps at different stages. It was found that the influence of process neps on yarn neps is dependent on fineness of the yarn.

Tear and Tensile Properties of Soda Pulps from Kenaf Bast Fibers.

A laboratory study evaluated the use of kenaf bast fibers in papermaking. The plant grows in a wide range of conditions and yields 4-8 metric tons of dry fiber per acre. The outer bark of the plant contains the long kenaf bast fibers. Multiple regression analyses modeled such physical fiber properties as tensile strength, tear factor, and..

On-Line Crimp Measurement.

Lenzing's CIS 200 automatically monitors crimp during manmade staple fiber production. Its two main components are a central control unit to set testing parameters and collect, store, transfer, and present data and optical sensors consisting of intelligent cameras with digital signal processors (DSP) and infrared lighting control. Each ca..

Conference papers included Cotton Market Overview, Cotton and the Consumer, MillNet Advancements, Is Your Cotton Y2K Compliant?, EFS System Windows Suite Development, Just-In-Time Advantages, Progress toward ..

Correlation Analysis of EFS Data.

Determining the relationship between data values for such fiber characteristics as micronaire, length, uniformity, strength, and yllowness could improve the precision of EFS data value analysis for cotton fiber laydown. During linear correlation analysis, the value of the correlation coefficient between any two of the cotton properties de..
