METHOD FOR MEASUREMENT OF THICKNESS AND DISTRIBUTION OF FUNGICIDE ON TEXTILES

MEASURING THE THICKNESS OF A FUNGICIDE COATING ON AN UNDERLYING TEXTILE FABRIC IS APPROACHED FROM TWO PERSPECTIVES, BOTH OF WHICH EXPLOIT THE DIFFERENT X-RAY SCATTERING PROPERTIES OF THE COATING AND BASE MATERIALS. BOTH METHODS PROVIDE A QUANTITATIVE MEASURE OF THE THICKNESS OVER 100% OF THE COATED AREA, WITH COATING THICKNESS RESOLUTION OF APPROXIMATELY 10%. BOTH METHODS ARE NONCONTACT AND CAN BE APPLIED IN A FACTORY ENVIRONMENT. TECHNICAL RISK FOR EITHER METHOD IS LOW, BUT THE UNSTATED REQUIREMENTS HAVING TO DO WITH THE COATING TYPE AND THICKNESS AND WITH INSPECTION ENVIRONMENT WILL FAVOR ONE OF THE TWO APPROACHES. THE WORK PLAN SHOWS HOW THE SELECTION OF THE BETTER OF THE TWO METHODS WILL BE MADE, AND THE PERFORMANCE VERIFICATION CONDUCTED. THE OUTPUT OF THE PHASE I PROGRAM IS A REPORT, AN INSTRUMENT DESIGN, AND A PROGRAM PLAN FOR A PHASE II FABRICATION AND IMPLEMENTATION OF A PROTOTYPE DEVICE.
