Abstract

Det er beskrevet en fremgangsmåte for fremstilling av en formdel, hvorved et fiberformig materiale på basis av syntesflbrer blandes med et klebemiddel og holdes under trykk i en form inntil avblndlng av klebe- middelet. Som fiberformig materiale anvendes det utelukkende et finfibret materialet med fibrer av en titer på l til 10 dtex og som klebemiddel et énkompo- nentklebemiddel. Mengden av klebemlddelet velges slik at andelen i den ferdige formdelen utgjør mindre enn 10 %, fortrinnsvis 3 til 5 %. På grunn av den enkle oppbygningen av bare en fiberkomponent og en lav klebemlddelandel egner formdelen seg for fornyet resirkulerbarhet. Foretrukket anvendesområde er anvendelsen som lyd¿ og varmeisolerende materiale ved innendørsbygging.There is disclosed a process for making a mold part, wherein a synthetic fiber-based fibrous material is mixed with an adhesive and kept under pressure in a mold until the adhesive is bleached. As a fibrous material, only a fine-grained material with fibers of a titer of 1 to 10 dtex is used and as a adhesive a one-component adhesive. The amount of adhesive portion is selected such that the proportion in the finished mold portion is less than 10%, preferably 3 to 5%. Due to the simple construction of only one fiber component and a low adhesive component, the molding part is suitable for renewable recyclability. Preferred application area is the use as sound and heat insulating material for indoor construction.
