rayon the formulation of a dispersion for fixing the fiber sheets is accomplished by the above described procedure and the requirements which the end product has to meet the usual additives for this procedure which include wetting agents antifoaming agents thermosensitizer softeners and smootheners anti static agents anti microbiotic agents dyes fillers flame retardants perfumes and the like may be used in general the dispersion is diluted with water to a binder content of 10 40 by weight the viscosity of the diluted dispersion may reside in the range of 10 10 000 mpa s for the fixing of battings e g of polyester polyamide or polyacrylonitrile fibers a liquid mixture of 15 25 is sprayed on the fiber sheet compact fiber webs and needle felts can easily be fixed upon impregnation with 10 40 dilutions followed by squeezing fluid and drying light fiber webs can also be fixed by foam impregnation for this purpose foaming agents and foam stabilizers are added to 10 25 solids diluted dispersion and foaming with air is performed up to a liter weight of 100 300 g the foam impregnation of the light fiber web is performed on horizontal foulard very light fiber web can be partially print bonded with pastes containing 20 40 binder and which have a viscosity of 4000 8000 mpa s needle felt for high quality floor and wall coverings are preferably slopped with thickened sometimes foamed mixtures finally web.
