Cleanroom Wipers -- Dynamic Wiping Efficiency.

Cleanroom wipes have applications as pads and for cleaning equipment and removing spills. Some cleanroom wipes do not wipe dry even when their capacities are not exceeded because pressure retards sorption or forces liquid from the fabric. Experiments evaluated the sorption, particle removal ability, and dynamic wiping efficiency of nine c..

Enhance Wiping Performance.

Tencel cellulosic fiber has a dry tenacity of 4.5-5.0 grams per denier, extension at break of 14-16 percent, wet tenacity of 3.9-4.3 grams per denier, extension at break of 16-18 percent, water imbibition of 65-70 percent, and degree of cellulose polymerization of 550-600. Applications of Tencel in wipes include patient bath cloths, kitch..

Airlaid Fabrics for Wipes.

Markets for air laid fabrics include feminine hygiene products (21 percent), dry wipes (21 percent), wet wipes (20 percent), tabletop (15 percent), diapers (5 percent), medical textiles (5 percent), and miscellaneous (13 percent). Advantages of air laid fabrics for consumer, cleaning, and industrial wipes include excellent scrubbing abili..

Wipes: Low Tech to High Tech, a Growing Market.

Air laid and spun laced nonwoven fabrics dominate the consumer wipes market. Consumer wipes impregnated with chemicals improve their cleaning or hygienic properties. Negatively charged consumer wipes have increased dust pickup. Woven and knit fabrics dominate the industrial wipes market, which accounts for approximately 30 percent of tota..

Fast Evaluation of Average Fiber Diameters of Nonwovens.

Researchers compared the results of the gas permeability method, the envelope surface area method, and gas adsorption surface area method to determine which provides the most accurate measurement of average fiber diameters . Porous Materials Incorporated's Average Fiber Diameter Analyzer measured the average fiber diameter of fibrous webs..

INTC 2001, International Nonwovens Technical Conference.

The INTC 2001 conference on nonwoven fabric manufacture addressed such topics as interprocess competition, melt flow index, bicomponent spun bonded and melt blown fabrics, processing speeds, activated carbon air filters, air filters, oil filters diameter measurement, melt blowing, finish uniformity, friction, surface modification, enzyme ..

High Performance and Flexible Spunbond Technology

Rieter Perfojet's Perfobond spunbonding machine, designed for polypropylene resin, manufactures a variety of products with different properties without equipment modification at speeds of up to 300 kilograms per hour per meter per beam. Each stage of the Perfobond process can be adjusted to correct problems, manufacture fibers or fabrics ..

Heterocapillarity of Nonwoven Cloth in Different Production Stages.

Researchers examined the effects of different processes used in the manufacture of nonwoven fabrics on the size and position of capillaries within the fabrics. A network of capillaries that communicated with each other characterized nonwoven fabrics. Experiments used needle punching and heat treatment to manufacture the nonwoven fabric sa..

The Influence of Process Conditions on Loop-Like Filament-Reinforced Nonwovens

A study to improve the strength of nonwoven geotextiles manufactured from staple fibers developed a frictional device that spreads filaments on a web to form a staple/filament/staple structure. An experiment evaluated the effects of different needle intensities and filament contents on the grab and tear strength of a nonwoven composite fe..

Index '02.

Index 2002 attracted 450 exhibitors, including nonwoven fabric manufactures, raw material suppliers, and nonwoven fabric manufacturing machinery manufactures. Fleissner GmbH & Company has sold 45,000 through air drums. 1,000 continuous nonwovwn fabric manufacturing lines, 50 advanced through air dryers with speeds of up to 2,000 meters pe..
