AT THE BEGINNING IS THE END.

Progressive managers in the nonwovens industry recognize the cost-effective benefits of the SHE concept, a responsible approach to industry safety, health, and the environment. These topics are of particular concern in the areas of waste, energy consumption, and fiber reutilization.

AUTOMATIC FAULT DETECTION POSSIBILITIES ON NONWOVEN FABICS.

Sensor technology has advanced to the point where the automatic Inspection of nonwoven fabrics is now more feasible. Electronic hardware and software available today can quickly detect and rectify faults, thereby increasing savings and justifying the initial investment in automated equipment. Three types of sensor technology systems are e..

NONWOVENS IN THE HOUSE BUILDING INDUSTRY.

A United States-based association for the nonweven fabrics industry, INDA, recently solicited the University of Tennessee ot head a research project cocering the use of nonwoven in home construction. Project directors immediately initlated the uiliding of a miniature model home composed of nonwovens, plastics, and composties made from a v..

Steadyview Tension Indicator.

Dover's SteadyView web tension indicator is microprocessor based and is easy to connect to any of Dover's tension transducers. The SteadyView takes the siganl produced by the transducers and displays actual web tension on a Hewlett-Packard LED display. The SteadyView can be configured to display tension in a variety of measurement units, ..

Pore Characterization in Nonwoven Fabrics - Shape Considerations.

Pore structure influences the physical and mechanical properties of nonwoven fabrics, including permeability. Conventional methods for determining pore size, such as sieving or hydrodynamic filtration, fail to identify pore shape characteristics. Researches developed invariant methods for the automated characterization of pore shapes by s..

Distribution of Crosslinked Polyols in Nonwovens and Relation to Functional Property Improvements.

Chemical treatments of nonwoven fabrics that differed in the binding method and fiber type involved the use of solutions containing polyethylene glycol, glycolated/alkylated dimethyloldihydroxyethyleneurea, and an acid catalyst (para-toluenesulfonic acid). Curing to insolubilize the polyol onto the substrates followed this treatment. Scan..

influence of silicone softeners on textile handle and mechanical properties. I. Subjective and objective differentiation of silicone softeners of different chemical structure

The use of near-infrared analysis as a technique of real-time quality control is highlighted. Products can be tested non-destructively in less than one minute. This is an English translation of an original German article; see abstract 93W/06582.

Flammability. Is it an issue?

The issue of nonwovens storage and flammability risk is considered, in the light of tests run by insurance companiew in the US which have resulted in more stringent conditions or higher premenums. The reliability of the tests conducted and their applicability to all nonwoven products have been called inot question by some in the industry...

Assessing fibre orientation in nonwoven fabrics

Fibre orientation is an improtant characteristic of nonwoven fabrics, as it directly influences their mechanical properties. In this paper Fourier analysis, pore analysis and flow-field analysis are discussed in relation to fibre orientation. Of the three forms of image analysis discussed, flow-field analysis is found to be the most suita..

Theoretical modelling and analysis of fibre pull-out behaviour from a bonded fibrous matrix: the elastic bond case

A theory to characterize the single fibre pull-out behaviour of bonded fibrous systems (eg nonwoven) is presented. Based on the shear-lag mechanism and the statistical-mean microstructural elements in the systems, the theory is developed for structures in which fibres are bonded with each other at contact point, and, as a result, the fibr..
