    Abstract  In order to improve stiff hand feeling of heavy cotton fabrics，water-soluble polyester fiber and cotton were blended，the influence of soluble polyester fiber content on fabric property was explored.Cotton/soluble polyester fiber blending ratios was separateed designed as 95/5，90/10，85/15 and 80/20，linear density of blended yarn was 27.8 tex，16 kinds of fabrics with four-up-two-down left twill were wove.After soluble polyester fiber in the fabric were dissolved，weight per unit area，thickness，air permeability，moisture absorption and quick-drying property，bending property and tensile property of the fabrics were tested and analyzed.The results showed that as content of soluble polyester fiber increased，softness of the fabric was significantly improved，strength of the fabric was reduced，bulkiness and moisture absorption were improved.It was pointed out when developing comfortable heavy cotton fabric，its warp content could be increased under the condition of the total soluble polyester fiber content in the fabric unchanged，design should be planned according to the use of the fabric.
