Analysis of dust resistance property of coated and laminated fabrics using newly developed instrument

摘要

Workers in the cement industry are engaged in the activities of packing, mixing, transportation and distribution. Being medium risk industry in terms of health hazards, workers are required to have protective work-wear to protect them from anticipating hazards due to the direct exposure of cement dust. Under this study an instrument has been developed to determine cement dust resistance nature of protective fabric. Six types of coated and laminated fabrics were tested on this instrument and their results are compared with air-permeability, hydrostatic head test and moisture vapour transmission properties of these fabrics.
