cotton is attacked by hot dilute or cold concentrated acid solutions. acid hydrolysis of cellulose produce hydro-celluloses. cold weak acids do not affect the cotton. the fibres show excellent resistance to alkalis. degradation cotton is degraded mainly by the hydrolysis effect of acids. effect of temperature...
