Abstract: Separation membranes are widely involved in medicine, textile, sewage treatment, food and other fields. But it found that single membrane materials existed the disadvantage of low mechanical strength and short service life. Because insufficient support leaded membrane pore to collapse, separation stability and permeability were affected, in order to enhance membrane mechanical strength, usually choosing fabric as support to composite membrane preparation.In the view of fabric, this paper aimed at reviewing developmemts of reinforced fabric composite membrane at home and abroad, four kinds of reinforced knitting fabric were analyzed therein. Finally, the characteristics and development direction of composite membrane with different structure were addressed.

Key words: fabric, composite membrane, reinforce ment, immerse precipitation
