Fibrous sheet obtained by a papermaking route, with improved dimensional stability for application especially in the field of advertising posters

摘要

In this fibrous sheet obtained by a papermaking route, containing a mixture of hydrophillic fibres, especially cellulosic ones, and of hydrophobic fibres, at least a proportion of the hydrophobic fibres are calibrated glass fibres with a diameter smaller than or equal to 8 micrometres and a length smaller than or equal to 4 mm, in a proportion making it possible to obtain a dimensional stability defined by a transverse elongation of not more than 0.7 % during a change from 14 to 94 % relative humidity.
