The Changing Role of Nonwoven Geotextiles in Civil Engineering Design.

Geotextiles can be used in teh soil for foundation structures of civil engineering works. Nonwoven fabrics for geotechnical applications include heat bonded and needle punched fabrics in weights ranging from 100-300 grams per square meter. The use of geomembrane plastic sheeting to seal landfill facilities, water reservoirs, and liquid la..

In 1998, the United States and Canada are expected to have a combined ＄3.3 billion in revenue for conventional nonwoven fabric, a 4 percent increase over the previous year. The hygiene and..

LASER CARD WEB MONITOR.

A web monitor more economical than the nucleonic transversing units adapted from the paper industry is needed. The development of a laser card web monitor based on principles used by the Autocount optical monitoring instrument is reviewed. The first attempt to produce an optical method of measuring web regularity suitable for nonwoven car..

SPECIAL METALLIC COATINGS ON NONWOVENS.

An autocatalytic method can be used to coat nonwovens with metal. The process consists of pre- and post-treatment and coating. The pretreatment sensitizes and activates the substrate for good adhesion with the metal. During coating, control of the thickness and homogeneity of the coating are critical. Post-treatment involves rinsing and h..

The 3-D structure of wet-laid glass fiber veils

Glass fiber veils are random, wet-laid structures of fibers and binder. Besides fiber and binder properties, the process conditions at different stages define the properties of the glass fiber web. The web thickness is an important parameter, defining other web properties, but its value cannot be defined from statistical analysis alone. A..

Identification of nonwoven binders by infrared microscopy in particular (German)

Because of the large variety of nonwoven binding products on the market, which are often used as mixtures, and the consequent wide range of variations or achievable effects and quality characteristics, the binding analysis is of interest for the incoming goods inspection and final checkout (quality assurance), for the assessment of intere..

Dutting and bonding of nonwoven with ultrasonlcs (German)

More and more converters of nonwovens and composite materials use ultrasonics. This technology allows high energy speeds, reduces the consumption of energy and eliminates consumables. Ultrasonics also allows material combinations, which so far only have been possible with glue. The main users of this technology are manufacturers of filter..
