Manufacturers of Air-Laid Nonwovens Look for Industrial Applications.

Worldwide air laid nonwoven fabric capacity exceeds 280,000 tons per year. Approximately half of this capacity is in Western Europe. Most air laid fabrics are used in the hygiene and disposable diaper markets due to their desirable absorbent properties. Emerging applications for air laid fabrics include filtraton, wound care, hospital dra..

Shipments of Fibers to Nonwovens Reported for 1999.

In 1999, total shipments by United States manufacturers of olefin, polyester, and rayon staple fibers increased 15 percent to 794 million pounds. Olefin staple fibers accounted for 57 percent of the market, whereas the polyester staple fibers market share fell to 35 percent. Demand for polyester and olefin staple fibers in the nonwoven fa..

Papers presented at the IDEA 1998 international nonwovens conference and exposition included Barrier Protection for Surgery in the Next Millennium; Planning for the Future -- Challenges for Medical Nonwovens; Communicating witht he U.S. Food & Drug Administration; Balancing Protection, Comfort, and Cost; Industrial Wipers for the New Mill..

OPTIMIZING POLYESTER NONWOVEN FABRIC THERMAL INSULATION

A method for calculating and optimizing the thermal conductivity of polyester-filled nonwovens is based on a detailed analysis of the heat transmission mechanisms involved. Infra-red optical data, such as the complex wavelength-dependent refractive index, enable the insulting properties to be calculated conditional to fiber fineness. Thes..

HEAT LOSS FROM A VENTILATED CLOTHED BODY

The heat flux from the surface of a hot body in an air stream was measured with a simple apparatus that obviated the need for a wind tunnel. Measurements were made with a range of polyester nonwoven fabrics. The results were analyzed on the basis of Take-Uchi;s theory. 6 refs.

SOUND ABSORBING PROPERTIES OF FIBROUS MATERIALS PREPARED BY THE AERODYNAMIC METHOD

An aerodynamic process was used to melt spin polypropylene fibers of varying diameters. The fibers were then heat bonded to form materials of varying density and thickness. The acoustical properties of these materials were measured. An equation was derived for the sound absorbing coefficient as a function of sound frequency and the struct..

NONWOVENS REPORT YEARBOOK 1990 BUYER'S GUIDE -- EQUIPMENT AND MATERIALS.

NONWOVENS REPORT YEARBOOK 1990 presents an equipment and materials buyer's guide for suppliers to the international nonwovens industry. The directory covers machinery and equipment; fibers, spunbonds, and carrier fabrics; resins and lattices; and associations, licensers, and consultants.

FIBER RECYCLING IN NONWOVEN INDUSTRY

Most waste in the nonwovens industry is generated during web consolidation and conversion in the form of edge trims, bad rolls, and off cuts. There are two basic methods of reopening waste in nonwovens manufacture. For on-line continuous processes, one cylinder openers are used. The material is fed between a wired feed roll and a dish to ..
