发明名称 Veil with a PVOH fibre binding agent
摘要 The process according to the invention comprises: a step in which chopped filaments and discontinuous PVOH fibers are dispersed in a process water, followed by a step in which a bed is formed in a forming device by passing the dispersion over a forming cloth through which the process water is drained, the filaments and fibers being retained on said cloth, followed by a heat treatment step in a stoving device. The PVOH fibers impart rigidity to the bed of fibers being formed. This process provides a veil with a very high tensile strength for low proportions of binder.
