A process for making a fabric structure, the process comprising the steps of: (i) obtaining a yarn of cellulosic filaments or fibres; (ii) chemically modifying the yarn to give the yarn gel forming properties; and (iii) knitting or weaving the chemically modified yarn to produce the fabric structure. The chemically modified yarn comprises from 50% to 100% by weight gel-forming fibres, and has a dry tensile strength of at least 10 cN/tex.
