INVESTIGATING THE EFFECTS OF WEIGHT VARIATION AND PATTERNING ON STRENGTH OF NONWOVEN PRODUCTS

In this study, the strengths of wet wipes, which are very popular in nonwoven products, have been studied. In the first part of the study, the machine and cross direction strengths of the standard and recycled products of the same unit weight during regular and faulty production were tested in dry and wet conditions. In the second part of the study, the strengths of the standard and patterned products in the machine direction and crosswise direction of the same unit weight were tested in dry and wet state. Study’s mathmatical and statistical results show that in terms of sustainability, it has been concluded that the use of recycle products can be produced in viscose / polyester with patterned form as disposable wet wipes by increasing the unit weight.
