Effect of washing temperature on smoothness appearance of woven fabrics during domestic tumble laundering

The effect of water and temperature on the smoothness appearance of woven fabrics is very significant during domestic tumble laundering. Thus,the setting of temperature is very important for washing parameter optimization. Five kinds of white and ordinary finished woven fabrics were selected and domestic tumble launderd at 20,30,45,60,75 ℃ respectively,and then measured their smoothness appearance,shear stiffness and bending stiffness. The results indicated that the smoothness appearance,shear stiffness and bending stiffness deceased with the increase of washing temperature. The reduction of smoothness appearance of pure cotton fabric is 1. 6 degree; and the pure polyester fabric is3. 8 degree. So the effect of washing temperature on polyester is more significant when compared with cotton.
