Anti-static cotton fabric and preparation method thereof

The invention relates to an anti-static cotton fabric and a preparation method thereof. The fabric can be prepared by adopting the following method: firstly, preparing SiC sol; secondly, preparing a polypyrrole solution; thirdly, adding the polypyrrole solution into the SiC sol to obtain composite sol; secondly, mixing the composite sol with a polyurethane coating agent to prepare a composite coating agent; finally, the surface of the cotton fabric is coated with the composite coating agent, and the anti-static cotton fabric is prepared. The point-to-point resistance of the anti-static cotton fabric prepared by the invention reaches 8.5 * 10 < 6 >-9.3 * 10 < 6 > omega, and the charged electric charge quantity reaches 0.23-0.28 mu C/piece; after 20 times of washing, the point-to-point resistance and the charged electric charge quantity are not greatly changed, so that the cotton fabric prepared by the method has a stable anti-static function. 本发明涉及一种防静电棉质面料及其制备方法。该面料可采用如下方法制得：首先，制得SiC溶胶；其次，制得聚吡咯溶液；再次，将聚吡咯溶液加入到
