Deteriorated dispersibility of hydroentangled wetlaid wet wipes over storage time

Description

Wet wipes came into public observation recently as sewage cloggings suggest these wipes
take a major role in the remains that block pipes and sewer systems. In this work it will be
shown that nonwoven wet wipes reduce their ability to disperse after a prolonged wet storage
condition. As storing nonwovens in a liquid is part of their eponymous usage as wet wipes, the
reduced dispersibility presents to be a crucial problem. A possibility to overcome this so-called
ageing effect of dispersibility is to use unbleached kraft pulp which with its elevated lignin
content seems to be able to prevent the ageing. With wet tensile tests it will be shown that the
ageing effect is not a manifestation of increased strength as the wet strength over the wet
storage time is unaffected.
