[papercreters] Re: Additives

Water content makes no difference to strength. Excess water drains out clear, the cement retained by the paper fibres. Compressing the material at this stage does make it denser, and dry quicker, if you wish. Plasticiser would only retard the drying process, which gains nothing.

If you mean plastic fibres, I've been interested in that too. The good news is they can be made in bulk for next to nothing using scrap synthetic fibre carpet. Cut into strips diagonal to the backing weave using an electric cutter (by hand its tough going) . Feed strips into garden shredder.
