Abstract:

Aiming at the short supply and little study on snow camouflage materials, and the complicated technical process of present materials, in this study, a new kind of polyester fabric having snow camouflage and UV protective properties was prepared by pigment printing technology, in which the nano-SiO2 particles were used as the white pigment, and the effects of pigments and binders on the snow camouflage properties were investigated，some of the wearability of the fabric have been tested as well. The results showed that the printed polyester fabrics had more than 80% reflectance in the UV region from 300 to 400 nm and had less than 5% T(UVA)AV value, and the UPF value was up to 300, all the value indicated that the printed polyester fabric has well snow camouflage and UV protective properties. In addition, the printed fabrics had good whiteness, handle, moisture permeability and soaping fastness.
