The traditional compression testers such as KESF (Kawabata Evaluation System for Fabrics) and FAST (Fabric Assurance by Simple Testing) systems are used to perform offline static measurements. The principle of online measurement of compressional behavior being developed is based on the analysis of fabric deformation while the fabric moves through a nip formed by a pair of rollers, one of which is controlled by a motor and is attached to a load cell. The specimen being tested is moved continuously through the measurement system, while it is deformed in compression at a constant rate in the nip area. The load-displacement relation of the fabric is then obtained as a function of time. Assuming a stepwise anisotropic behavior in the thickness direction, the fabric stress-strain relation in compression is obtained.","PeriodicalId":117593,"journal":{"name":"1999 IEEE Annual Textile, Fiber and Film Industry Technical Conference (Cat.

The technology, called diesel no-break, has been successfully installed and operating for many years around the world. Hitec Power Protection of the Netherlands developed this technology over three decades ago. Only in the last few years have US facility managers discovered this dependable, cost effective alternative to conventional battery-based UPS systems. Diesel no-break systems provide clean continuous, extended power outage protection, which enables customers to avoid costly surges and sags in their critical load power. US facility managers and engineers cite reliability and power quality as the major criteria in choosing this technology. Reliability is enhanced by lower parts count, which translates to less maintenance and coordination with fewer suppliers. Hitec's ISO9001 certification ensures stringent quality control in the design and manufacturing of the system. The nature of the system-extended power outage protection and continuous active voltage regulation and filtering-result in high quality power afforded to the customer.","PeriodicalId":117593,"journal":{"name":"1999 IEEE Annual Textile, Fiber and Film Industry Technical Conference (Cat.

The approach is generic and applicable to a variety of industrial plants that operate critical processes and may require continuous monitoring and maintenance procedures. A dual approach is pursued: high-bandwidth fault symptomatic evidence, such as vibrations, current spikes, etc., are treated via a feature extractor/neural network classifier construct; while low-bandwidth phenomena, such as temperature, pressure, corrosion, leaks, etc., are better diagnosed with a fuzzy rule base set as an expert system. The technique is illustrated with typical examples from benchmark processes common to many industrial plants.","PeriodicalId":117593,"journal":{"name":"1999 IEEE Annual Textile, Fiber and Film Industry Technical Conference (Cat.

With the goal of identifying unique power quality problems and solutions, the Electric Power Research Institute (EPRI), Duke Power Company, and other industry \"players\" embarked on a Power Quality Initiative in late 1997. The initiative involves equipment testing for five process types: blown thin film, plastic jacket, thick film, injection molding, and plastic pipe extrusion. CommScope Incorporated of Hickory, NC became interested in the initiative at its inception and has since then partnered with EPRI, Duke Power and the Polymers Extension Program to test their extrusion equipment, implement solutions, and has offered their case study to promote this Power Quality Initiative.","PeriodicalId":117593,"journal":{"name":"1999 IEEE Annual Textile, Fiber and Film Industry Technical Conference (Cat.

The fast switching rates of PWM drives generate high frequency currents and induced potentials on the motor, drive and interconnected equipment. This leads to premature motor bearing failure and electrical interference to the drive and nearby equipment. Research shows solutions related to the power cable dictate a construction that must provide an effective electrostatic shielding for isolation of the high frequency currents and potentials, and an effective low impedance path to ground for draining canceling ground currents. This paper presents an overview of the benefits and drawbacks of typical National Electrical Code power cable constructions that help reduce or eliminate the problems associated with PWM AC adjustable-speed drives.","PeriodicalId":117593,"journal":{"name":"1999 IEEE Annual Textile, Fiber and Film Industry Technical Conference (Cat.

In order to measure the variation in the compression force during a test, a full bridge load cell was developed. It was seen that the signal coming from the strain gages was superimposed with noise. It was also found that the noise was from both electrical and mechanical sources. An extensive mathematical analysis of mechanical noise and the application of a mechanical noise reduction technique minimized the mechanical noise component. Analysis of electrical noise showed that the motion control card was interfacing with the data acquisition (DAQ) card via both the RS232 and the AC power line. It was necessary to separate the motion control unit and the DAQ unit in order to eliminate the electrical noise problem present in the system. After eliminating the noise from the unit, the calibration of the strain gages has been performed. The coefficient of correlation was found 1.00 with a cubic model.","PeriodicalId":117593,"journal":{"name":"1999 IEEE Annual Textile, Fiber and Film Industry Technical Conference (Cat.
