Nonwovens.

Manufacturers of machines for carded nonwoven fabrics far outnumbered those of spun bonded nonwoven fabrics at ITMA 1999. Fleissner was the only company to present machines for hydroentanglement, and no company demonstrated air laid or melt blown nonwoven fabric manufacturing equipment. Fleissner received orders for two heat setting/fixat..

COTTON -- A RENEWABLE RESOURCE FOR OIL SPILL CLEANUPS.

Sorbents aid in the cleanup of oil spills since a sorbent-oil mixture, which behaves differently than a fluid, is easier to retrieve than oil alone. Sorbents can also capture and retain oil for later retrieval. A properly selected sorbent should pick up at least 90 percent of the oil it encounters. The ideal sorbent is oleophilic, hydroph..

A Model fo Calculating the Noise Absorption Capacity of Nonwoven Fiber Webs

Nonwoven fabrics have a wide range of applications as noise control elements. A numerical method calculates their acoustic performance based on the Zwikker and Kosten theory of sound propagation through porous media. Results for nonwoven fabrics manufactured from acrylic, cotton, and polyester fiber were in fair agreement with experimenta..

Developments and Applications in Japanese Nonwovens

Until recently, Japanese nonwoven fabric manufacturers developed products almost exclusively for domestic consumption. A wide variety of manufacturers gives the industry its synergy. These manufacturers are beginning to market their nonwoven products directly. Sanitary products remain the largest application for nonwoven fabrics. Baby dia..

Fleissner Technologies for the Nonwoven Industry

At Index 1999, Fleissner showed its new line of machines for the nonwoven fabrics industry, including the AquaJet hydroentanglement line; installations for thermal bonding, spray bonding, and chemical bonding; High-Tech through-air drying machines for nonwoven fabrics, paper, and tissue; foam impregnating lines; heat setting lines; bondin..

The World Technical Textile Industry and its Markets: Prospects to 2005

A survey of potential markets and market developments in the technical textiles industry addresses changes in the competitive environment and market trends in the agriculture, building construction, fabric, geotextile, home furnishings, industrial, medical, transportation, packaging, and athletic sectors. The survey examines market potent..

Measuring Fiber Diameter Distribution in Nonwovens.

Image analysis to characterize fiber diameter distribution in nonwoven fabrics uses a distance transform. A binary image creates a distance map that records the distance from each pixel to the background and determines the fiber diameter at any pixel location. Verification involves a series of simulated and real nonwoven fabric images. Sa..

Fabric is Good Host for Micro-organisms.

A joint research project of Kajima Corporation and Nippon Sheet Glass Company resulted in a new material that accommodates useful microorganisms in high densities. The nonwoven fabric is made of carbon fibers. It allows large quantities of microbes to inhabit its fine texture. The nonwoven fabric can be used in bioreactors that culture mi..

Aerodynamic Web-Forming on Random Cards.

To improve web quality, Fehrer AG modified its nonwoven fabric V21/R feeding unit and K12 carding machine. This nonwoven web forming line features a working width of 4.4-5.4 meters. For a width of 4.2 meters, the line consists of a feeding tower and a hopper feeder that transforms the fiber to a mat of the required width. A weighing stati..

Technical Nonwovens from Jute and Jute Blends.

A process devised by the British Textile Technology Group for the manufacture of jute/manmade fiber nonwoven fabrics involved conventional jute batching; breaker card production of heavy sliver; cutting breaker card sliver into processable staple lengths; mixing jute and manmade fibers in jute-heavy ratios; fleece formation using a roller..
