A Hybrid Market for Nonwoven Fabrics.

Product and process development in the nonwoven fabric industry derives from a range of sources, including innovation in the paper, polymer, and textile industries. A review of product and process development describes Kimberly-Clark's spunbonding/melt blowing/spunbonding technology; 3M's Thinsulate; webs that mold in water; the manufactu..

High Loft Nonwovens

High loft nonwoven fabrics are at least 3 millimeters thick and contain not more than 10 percent solids by volume. Chute feeding systems deliver the opened fibers to the carding and air laying machines with uniform weight in the machine and cross directions. Modern carding machines produce a 3 OSY web at a rate of more than 50 meters per ..

Nonwoven Fabrics, Spunbonded.

Disposable diaper coverstock accounts for approximately 50 percent of the United States coverstock market and remains the largest growth area for spun bonded fabrics. Overall growth in the spun bonded fabric market is expected to be 7 percent per year during the next several years. Other growth areas include hygiene products, geotextiles,..

Stitchbonded Fabrics 1999

Stitch bonded fabrics were developed in Europe in the 1950s. The early concept, which involved stitching through a fibrous material to add integrity and strength, has grown into an array of complex and complicated products. Many variations on the original process use special needles to yield products with special properties. Some current ..

New Dimensions in Nonwovens through Hybrid Technologies.

In the future, greater use of acrylic, carbon, ceramic, polyolefin, Kynol novoloid, hollow, Teflon fluorocarbon, Gore-Tex expanded fluorocarbon, Lenzing polytetrafluoroethylene, Kevlar and Twaron aramid, polyetheretherketone, polyetherimide, polyimide, polyethylene naphthalate, polytrimethylene terephthalate, polybenzimidazole, polyvinyl ..

Wet-Laid Nonwovens

Wet laid nonwoven fabric manufacture involves suspending fibers in water and controlling the way in which the fibers and water are separated. Modified paper manufacturing technologies bond and dry uniform mats of fiber to produce rolls nonwoven fabric. Although methods that use high volumes of water per fiber content reduce defects due to..

Beyond Melt Blowing: Process Refinement in Microfibre Hot Melt Adhesive Technology

Nordson Corporation's Control Weave technology for applying hot melt adhesive consists of a small number of well spaced nozzles with two air holes on either side of each polymer outlet. The unique configuration allows repeating nozzles both within a die module as well as between modules. Die configuration orientation takes advantage of fi..

Evaluating Nonwoven Fabric Irregularity on the Basis of Linnik Functionals

Researchers developed new statistical characteristics for analyzing the irregularity of nonwoven fabrics based on homogeneity and nonhomogeneity of random field irregularity (RFI). Characteristics of nonwoven fabric irregularity that are important to practical applications are classified as outliers of RFI beyond or beneath a fixed level...
