Crosslinked cellulosic material esp. paper pulp - by reacting dehydrated, non-swollen fibres with crosslinking agent
Реферат: Crosslinked cellulosic material esp. paper pulp, is prepd. by (a) converting the material into dry, dehydrated non-swollen individual fibres without inter-fibre bonds, and (b) treating with a crosslinking agent, esp. formaldehyde in a medium having a sufficiently low water content to avoid swelling the fibres during crosslinking. Gives prods. with a high water absorption, high resilience soft touch and low density.
Low hemicellulose, dry crosslinked cellulosic absorbent materials
