Chemical recycling of cotton-based waste textiles by sulfuric acid
linens labeled 100 cotton were dissolved and hydrolyzed in sulfuric acid to produce a glu- cose solution without the need of enzymes One-step hydrolysis |
Cotton is the complete opposite.
It's ok in a strong Caustic solution but will disintegrate in a strong acid solution like sulfuric or formic .
Nylon is severally effect with formic but not with sulfuric.
What is the effect of sulphuric acid on cotton?
It is shown that treatment with 10% sulphuric acid already causes distinct tendering of cotton hairs or yarns and that complete disruption is caused by acid containing about 77 grms, H2SO4 per 100 cc.
With single hairs, the tendering effect is directly proportional to the concentration of the acid.
What chemical dissolves cotton?
Sodium hydroxide/urea (NaOH/urea) aqueous solution is one of the preferable inorganic dissolution systems for cellulose to prepare regenerated cellulose.
NaOH/urea aqueous solution can destruct the intermolecular hydrogen bonds of the cellulose to dissolve cotton effectively.
