The effect of repeated laundering on properties of needled and calendered nonwoven cleaning materials produced with different process conditions

The aim of this study is to evaluate the physical and performance properties of needled and thermal bonded nonwoven cleaning materials produced with different conditions after changing washing cycles; 0,1,5 and 10 cycles. for this purpose,5 different nonwoven cleaning materials with different areal weights containing polyester and viscose fibers and produced by either calendering or through air bonding after needling process was selected as material. all the samples were washed with standard washing procedures for 1,5 and 10 times and tested before and after washing cycles. the variation in areal weight,thickness,bulk density,abrasion resistance,bursting strength and water absorption capacity was analyzed and assessed in detail considering production process difference. the results derived from the study indicated that through air bonded samples had better performance properties after washing cycles compared with calendered counterparts.
