Polypropylene Melt-Blown Nonwovens as Absorbents of Oil-Type Substances

The Polish Textile Institute in Lodz has developed a group of oil absorbent nonwoven fabrics based on polypropylene microfibers. Tests assessed the oil asorbing capacity of flat polypropylene melt blown nonwoven fabrics with varied content per volume (packing density) and fiber fineness of the elementary fibers. Oil absorption performance..

Protective Clothing and the Role of Nonwovens

Nonwoven fabrics occupy a major role in the fragmented and complex protective clothing market. According to the Industrial Fabric Association International, the protective clothing market in the United States totals 200 million square yards, exclusive of

Future Growth for Airlaid Webs

Heretofore, the primary end uses of air laid fabrics have been wipes, napkins, and hygiene products. For converters and end product manufacturers to utilize air laid fabrics on a broader scale, cooperation would be required to create new markets and establish the new material with cosumers. Duni, a leading air laid fabric manufacturer, cr..

Web Improvement

Fiber orientation after exiting the carding machine plays an important role in the lengthwise and crosswise resistance of the web. Some carding machines, particularly those manufactured by Thibeau and Spinnbau, offer attachments that allow for the manufacture of homogeneous webs with different fiber orientations. This feature facilitates ..

Biodegradable nonwovens

An environmentally-friendly 100％-biodegradable and compostable nonwoven has been developed by Fiberweb France SA. The product is based on polylactic acid polymers, which are polyesters composed of chains of lactic acid. Nonwovens based on these materials have applications in agriculture, filtration, hygiene and protective clothing. Their..

AIR PERMEABILITY OF NONWOVEN FILTER FABRICS. PART 3.

An instrument was fabricated for measuring the filtration parameters of filter fabrics. The designs of the apparatus and earlier instruments are described. The new instrument comprises a fabric holder, an absolute filter, an orifice meter, and a valve, suction pump, funnel, ventrui tube, disk, scraper, rotor, hopper, and compressor. One m..

MEASUREMENT OF FIBER FRICTION AND ITS IMPORTANCE IN MANUFACTURING COTTON NONWOVENS

An attempt to measure the frictional characteristics of staple cotton fiber webs is described. A modification of the sied friction test for plastics was used to measure the shear of a layered carded web of five cotton samples under normal load. Another experimental apparatus, a beard friction force tester, allowed for measurement of fiber..

FIBER OPENING AND BLENDING LINE FOR NONWOVENS

Laroche has developed a fiber opening and blending line for nonwovens. The line consists of a weight pan feeder, blending conveyor, pre-pener, and fine opener. The weight pan feeders are 1,000, 1,600, or 2,000 millimeters in width. The weigh pans fit on an independent frame; load cells are linked with a weight controller. Feeders have eit..

EXHAUST AIR PURIFICATION FOR THE TEXTILE INDUSTRY.

Behr in Stuttgart, Germany, has developed a new mechanical and electrostatic filter to remove solid and liquid particles from the exhaust air of thermal processes. Particles down to a size of 0.00001 millimeter can be removed. The filiter operates cost-effectively in combination with a heat recuperation system. About two-thirds of the pol..
