CONSTRUCTION OF BOUND FIBROUS MATS

Disclosed is a system and method for constructing fibrous mats. In accordance with the disclosure， continuous lengths of filament are pre-coated with a liquefied thermoplastic. The pre-coated filaments are then laid down upon a belt to forum a fibrous mat. The filaments can be laid down in continuous lengths or they can be chopped into discontinuous lengths. The filaments are heated after they have been laid down in order to re-liquefy the thermoplastic and facilitate bonding between intersecting fibers. The disclosure further relates to a system and method for incorporating constructed fibrous mats into a composite building board.

本公开提供了一种制备纤维毡的系统与方法。根据本公开内容，连续长丝预先涂覆液化热塑性材料；随后将预涂覆后的长丝铺设于传送带上以形成纤维毡。所述长丝可采用连续长度铺设，亦可被切割为不连续长度。长丝铺设完成后将被加热，以使热塑性材料重新液化，从而促进交叉纤维间的粘结。本公开还涉及将制备完成的纤维毡集成至复合建筑板材中的系统与方法。
