The disclosure relates to the production of a mineral fiber product for example to replace asbestos fibers in different products. In the method of production, at most 7% by weight of mineral fibers is dispersed in water which contains a wetting agent, undispersible material being then separated and the dispersion being then mechanically dewatered to a dry content of from 30 to 70% by weight and a fiber density of from 200 to 400 kg/m3. In a subsequent, separate stage, the fibers are redispersed in water substantially without the addition of wetting agent, are provided with possible additives such as cellulose fibers, are shaped, dewatered and dried. |
