Abstract

The new method combination is aimed at improving and regulating the adhesion between similar or different fibers in connection with a method for producing hydroentangled and thermobonded fabrics from cellulose and synthetic fiber blends. Improvement of the fiber adhesion aims at providing highstrength and well absorbing, stable, non-linting nonwoven structures containing high cellulose concentrations. In the new method, adhesion strength is improved by increasing kinetically and quantitatively the contact and wetting between molten polyolefin used for cellulose bonding, and the cellulose, and providing in the cooling contact site transcrystallization following heterogenous nucleation of the polyolefin structure. In order to provide for pre-contacts between the cellulose and cellulose-polyolefin fibers, effectivated hydrogen bonding between the cellulose fibers is used, especially when mechanically hydroentangling cellulose using unreacting synthetic fiber (polyamide, ester). In order to improve adhesion strength, the surface structure of the polyolefin and/or cellulose fibers has to be modified. The surface structure of the polyolefins is modified by molecular chain degradation caused by spinning oxidation, in order to decrease the surface energy, viscosity and temperature of the surface melt formed in bonding. The modification of the cellulose surfaces takes place by heat treatment in a polar liquid, whereby in connection with a conversion of the cellulose crystal structure (C-II (C-I) -> C-IV), its surface energy, crystallinity degree and crystal lamellar thickness of its superstructure increase. Hydrogen bond formation is activated with a combined corona and steam wetting-pressure-drying method.
