Abstract

~ Grams per square meter (GSM) or Grammage is an ISO recommended term to express the mass per unit area of papers, metal sheets, plastic made products and fabric materials. GSM tests are mainly done in textile industry to measure GSM  of knitted fabrics and to ensure other standard specifications of fabrics. Meanwhile, the manual GSM measuring procedure is preferred by most of the textile organizations, which leads to many disadvantages including fabric wastage. As an alternative solution for this industrial issue, an automated non-contact type fabric Grammage measuring method is proposed. This paper introduces mathematical models for determining GSM values based on beta particle absorption characteristics of three selected fabrics. Moreover, this study discusses a real-time GSM measuring system, which utilizes the generated mathematical models. Through this paper, developed mathematical models are investigated over goodness of fit parameters. Developed models are appropriate for GSM value estimation with R² values over 0.99 and lower Root Mean Square Error (RMSE) Values.  Error percentages obtained during validation of these mathematical models are less than 1% for all fabric types.
