Patent ID: 10493718

Abstract:
A liquid-absorbing multi-layered sheet with a liquid-absorbing central layer and a first and a second outer layer of fibers, tissue or film provided at each their side of the central layer is provided. The central layer is airlaid and includes cellulosic fibers, superabsorbents and heat-adhesive binder fibers. The sheet is peculiar in that the percentage of heat-adhesive binder fibers in the central layer is between 1% and 7% of the total weight of fibers in the central layer. In production, a continuous web with the three layers is conveyed through a heating zone for heating the web, wherein the heating temperature and the heating time are adapted to at least a partial melting of the heat-adhesive binder fibers in the central layer for binding the fibers in the central layer and for binding the outer layers to the central layer.
