In order to find out the influence of tuck on fabric properties, single tuck knitting fabric was taken for example. Ten kinds of samples, including nine tuck stitch and one plain, were woven with same yarn and sinking depth by changing the ratio and times of tuck. Fabric properties such as course, wale, thickness, surface density, air permeability and heat retention were tested, and the effects of tuck ratio and tuck times on fabrics were investigated. Moreover, experimental data were used to do a regression analysis. The results show that, compared with the plain fabric, tuck makes the fabric wale density, thickness, surface density, air permeability and heat retention increase, but course density decrease. When tuck times fixed, tuck ratio has a line relationship separately with course density, wale density, thickness, surface density and heat retention, but has a quadric relationship with air permeability. When tuck ratio fixed, tuck times has a quadric relationship with course density, wale density and heat retention, has a quadric or line relationship with air permeability, and has a line relationship with thickness and surface density, respectively.Moreover, experimental datum was used to do a regression analysis with least square method. The results show that tuck makes the fabric width, thickness, surface density, air permeability and heat retention increase, but length decrease. Tuck number, percentage has a line relationship with thickness and surface density, and has a quadric relationship with course, wale, air permeability and heat retention respectively.
