ABSTRACT:
Sheet products are made from amino-aldehyde, e.g. urea-formaldehyde, resin fibres in admixture with other non-cellulosic fibres, e.g. glass fibres, and optionally cellulosic fibres. Multiply products may be made from plies having the above constitution and plies of, for example, amino-aldehyde resin fibres, alone or in admixture with cellulosic and/or non-cellulosic fibres. The paper-like sheet materials may be used e.g. as filter papers.
Laminated products may be made by pressing at an elevated temperature, a stack of plies of paper made from a mixture of amino-aldehyde resin fibres and another fibrous material, e.g. cellulosic fibres.
