Abstract
A method of quantifying the removal of hydrocarbon component from a soiled fabric by a washing process, wherein the soiled fabric includes at least about 0.5 wt % hydrocarbon component wherein the method uses near infra-red (NIR) analysis, wherein the method includes the steps of: (a) performing non-contact NIR analysis of the soiled fabric to determine the concentration of hydrocarbon component present on the soiled fabric at multiple points; (b) washing the soiled fabric to obtain a washed fabric; (c) performing non-contact NIR analysis of the washed fabric to determine the concentration of hydrocarbon component present on the washed fabric at the same multiple points that were used in step (a); and (d) quantifying the removal of hydrocarbon component from the soiled fabric by the washing process.
