FIELD: manufacture of nonwoven fabric from filament or particles.
SUBSTANCE: method involves preparing foamed suspension; delivering said suspension onto perforated member comprising three-dimensional mold; forming fabric of three-dimensional shape, said fabric having shape substantially differing from flat shape, by removing foam from foamed suspension through perforated member; drying fabric. Apparatus for effectuating said method is also described. Method may be used for manufacture of wide range of products, including corrugated filters for air and liquids for automobiles, corrugated filters for aspiration masks and antibacterial filters, and also laminated cleaning articles with superabsorbing central layers, such as floor cleaning cloth which is formed so that it may be easily put onto mop base, and other articles.
EFFECT: increased efficiency, wider range and improved quality of products manufactured from fibrous fabric.
