IDEA /01 Brings Nonwovens Industry Leaders to Miami.

The International Nonwovens Conference and Exposition (IDEA) 2001 attracted more that 330 exhibitors and 7,000 nonwovens industry include allergen barrier fabrics, negatively charged dusting wipes for home use, and disposable HEPA filters for vacuum cleaners. Novel automotive headliners feature face, adhesive, and backing components deriv..

Comparing Nonwoven Processes.

Nowoven fabric manufacturers selecting between carding/garnetting, air laying, needle punching, hydroentangling, wet laying, spunbonding, melt blowing, stitch bonding, scrim, and tow processes must consider investment costs, raw materials costs and availability, labor, shipping, inventory, liability, prospects for future developments, mar..

Nonlinear Mechanics of Woven and Knitted Materials

An introduction to nonlinear stress-strain relationships in fabrics addresses the mechanical properties of woven and knit fabrics and their role in composites. The biaxial extension theory describes a fabric structure with parameters determined by the warp and weft density and the crimp shrinkage in both directions. The shear deformation ..

The Filtration Boom

The filtration market is the fastest growing segment in the nonwoven fabric industry, and nonwoven fabric filters are gaining market share from paper and woven fabric filters. Competition has increased as more nonwoven fabric manufactures have focused on the filtration market. Analysts believe manufacturers must offer a broad range of pro..

Leading Technology in Filtration

Gebr. Kufferath GmbH and Company's new YMAX fiber and wire composite filtration media combines surface and depth filtration properties for such industrial applications as solid/quid separation and hot gas or polymer filtration. Its principal advantage over conventional filtration systems is its high porosity of up to 60 percent. Sintered ..

Natural Fiber-Reinforced Biodegradable Matrix Composite: Effect of Surface Modifications of Jute on the Performance of Jute-Biopol Composites

Fourier transform infrared and thermal gravimetric analyses established the effectiveness of different surface modifications of jute based samples (hessian cloth, HC and yarn, and JY) as reinforcements in composites manufactured from the biodegradable polymer matrix Biopol. JY reinforced composites exhibited a 100 percent increase in tens..

Flexible Composite

Flexible composites manufactured from fiber or fabric reinforced elastomers have applications in the manufacture of pneumatic tires, air springs, flexible couplings, diaphragms, and other membrane structures. These feature a rubber matrix that is less rigid than the reinforcing fibers in conventional composites. An overview of unidirectio..

Composite with Cellulose Esters

Novel lyocell fiber reinforced composites use cellulose (mixed) esters as the matrix. Continuos filaments reinforce the thermoplastic matrix, which adheres strongly to the cellulosic fiber surfaces without compatibilizers. Composites with a fiber content of 60 percent possess tensile modulus of greater than 20 gigapascals. Compared with s..

Development of Clay Minerals/Organic Polymer Nano-Composite Materials

Researchers used cation exchange of montmorillonite for amino acid cations and polymerization of epsilon-caprolactam in interlayer regions to develop a nanocomposite organic polymer with clay minerals. Nylon clay hybrid materials, in which the silicate layers were approximately 1 nanometer in thickness, were dispersed in the nylon 6 matri..
