Abstract:

In order to obtain a cold comfort knitted fabric, cotton fabric was treated with cellulase, followed by iced silicone oil finishing. The properties of tactitity cool cotton fabric were studied by Fourier transform infrared spectrometer (FTRI), thermogravimetric analysis (TG), KES fabric style instrument, capillary effect, air permeability, moisture penetrability, thermal resistance and water-vapour resistance test. The results show that shearing rigidity of the cool cotton fabric is 0.74 cN/ (cm?(°) ), the bending rigidity is 0.007 3 cN?cm and the drape coefficient is 30.7%. The capillary effect of the treated fabric is 12.3 cm(30 min). The air permeability is 352.3 L/(m2?s). The moisture penetrability is 4.012 g/(m2?d). The thermal and water-vapour resistance is 0.019 1 m2?°C/W and  4.687 Pa?m2/W, respectively. The surface softness and smoothness of cotton fabric increase after cellulase and iced silicone oil treatment. The coefficient of kinetic friction of the treated sample is 0.206. The average friction coefficient is 0.006 2. The surface roughness is 2.250. The FT-IR anslysis indicates that silicone oil group is introduced to the treated fabric surface. Teh thermal gravity analysis result shows that the temperature of initial thermal decomposition temperature of transient cool feeling cotton fabric is 247.7°C. The thermal stability of the treated fabric maintains good.
