Single jersey fabrics have been used commonly because of their flexibility, airpermeability and elasticity. But they are unstable in dimension, specially in fabricsknitted from wool and cotton yarn. Detergents affect mechanical properties ofknitted fabrics. Using the natural detergents minimizes the environment impact. Inthis research we investigated the influence of detergents on dimension stability andon skew in single jersey fabrics. Three detergents were used, which were Suft liquiddetergent, liquid detergent for wool garment with pH = 7.0 and liquid detergentextracted from soap-berry. Two kind of investigated single jersey fabrics knittedfrom CVC yarn (60% cotton, 40% Polyester). The fabrics have been washed anddried 3 cycles. The results showed that all fabrics took the dimensional change incourse and wale direction. There was no clear difference from the detergents on thefabric dimensional change. Liquid detergent extracted from soap-berry mostaffected on skew in knitted fabrics but this value was less changed in comparisionto the initial value of the fabric before testing.Vải dệt kim single được sử dụng rộng rãi nhờ sự mềm mại, thoáng khí và khảnăng đàn hồi.
