ITMA '99 Survey 21 : Nonwovens Equipment.

An overview of nonwoven fabric manufacturing machinery shown at ITMA 1999, in Paris, addresses current applications, new developments, and future trends. Fleissner and ICBT International showed their Aquajet and Jetlace spunlacing machines, respectively. Dr.Ernst Fehrer AG, Shoou Shyng Machinery Company Limited, Asselin of N. Sclumberger ..

Measuring fiber diameter distribution in nonwovens

This paper reports the application of image analysis methods we developed previously to characterize fiber diameter distribution in nonwovens using a 'distance transform.' The method is verified by a series of simulated nonwoven images as well as some real web images used previously, including a carded web, a relatively dense spunbonded f..

Measuring fiber orientation in nonwovens. Part V: Real webs

This paper extends the work of the first four parts of this series to apply the image analysis methods we have developed to characterize the fiber orientation of real nonwoven fabrics. The 'real' fabrics chosen as typical are a carded crimped fiber web, two relatively dense overall or area bonded fabrics, a pattern or point bonded spunbon..

HYgienico -- A New Self-Modelling Nonwoven Mini-Garment for the Hygienic Protection inside Helmets.

Mambretti Incorporated's Hygenico nonwoven fabric insert for protective helmets increases the protective surface of the forehead, eyes, and neck areas. Key advantages include soft contact with the skin; good sweat absorption; thermoinsulating properties; and protection from dust, pigments, fumes, and other airborne pollutants. In addition..

Nonwovens in Air Filtration.

An overview of nonwoven fabrics with applications in air filtration addresses the availability of raw materials, manufacturing techniques, and environmental safety. New developments in nonwoven fabric manufacture include the use of lyocell and heat resistant olefin fibers. Key techniques include spunbonding, melt blowing, and composite ma..

Structurally Engineered Air-Laid Webs.

Researchers studied the structure of air laid fabrics manufactured from viscose fibers and determined the effects of suction conditions. A Kroyer type air entangling machine with rotating blades formed the sample fabrics. Laser Doppler velocimetry measured velocity fields. A Kodak EKTAPRO HS Moion Analyzer Model 4540 characterized fiber d..

Carding Plus Airlaid.

An overview of nonwoven fabric manufacturing addresses the advantages and disadvantages of carding and air entangling machines. Disadvantages of mechanical web forming techniques, such as carding, include limits on nonwoven fabric weight, fineness, and evenness, particularly in the manufacture of light weight nonwoven fabrics. Air entangl..

Nonwovens from the Internet?

Lantor, a leading European nonwoven fabric manufacturer, developed an Internet site in 1996. Since its inception, the number of site visitors increased from 3,000 to 6,000 per six month period. These data, however, include accidental visits. Of all the inquiries, 10 percent were general questions, 83 percent were product or service specif..

Technical Nonwovens at Index '99.

Major trends for industrial nonwoven fabrics at INDEX 1999 included the use of innovative raw materials and novel manufacturing processes. Manufacture of Fabriano Soft's new spun laid nonwoven fabric of metallocene polypropylene uses a metallocene catalyst during polymerization to produce a homogeneous molecular weight distribution that r..

INDA-TEC 99: Book of Papers: International Nonwovens Conference.

INDA's international nonwoven fabric conference included such topics as segmented bicomponent fiber engineering for specific end uses, melt extruded fiber properties and performance levels, planar absorbency rates, interaction of proteins with feminine hygiene products, spin finishes, air laid fabric composites, superabsorbent polymers, m..
