Abstract

PURPOSE:To speedily obtain a heat insulating mat without nonuniformity in strength or heat insulating properties by uniformly dispersing wood fiber having a fiber length below a specified value together with a thermowelding binding agent by a fibrillating machine to form a dry nonwoven mat. CONSTITUTION:Wood fiber of fiber length below 10mm., such as corrugated board or waste paper, is granulated into proper sizes and sent from a quantitatively feeding apparatus A into a fibrillating machine, into which a thermowelding binding agent is also sent from a quantitatively feeding apparatus B. The wood fiber and the thermowelding binding agent are compounded in the proportion of 100% to 5-70% by weight. After fibrillation and mixing, a mat is formed by a mat former. Said mat is passed through a hot-air through-type heating oven to apply a heat treatment so that the binding agent binds between the fibers and between the fibers and the binding agent itself, to obtain a dry nonwoven mat of apparent density 0.02-0.1g/cm<3>.
