[Common textiles manual] Non-woven cement bag cloth

Overview

Non-woven bag cloth for packaging cement. The non-woven cement bag cloth using polypropylene as raw material requires longitudinal tensile strength greater than 294.2N/5cm, free fall from the height of 1cm after packaging 5 times without bulk bag, the mass per unit area is 80~100g/m2, using the hot rolling process Processed. The non-woven cement bag cloth with vinylon as raw material requires a longitudinal strength of 98N. There are still requirements for bursting strength, tear resistance, air permeability and moisture. The mass per unit area is 60~80g/m2, and the chemical viscous process is used. Processed.
