Preparation and Application of Novel Cationic Fluorinated Polyacrylate Latex in Leather Waterproofing

Article Preview

Abstract:

Novel cationic fluorinated polyacrylate latex was synthesized and characterized using Infrared spectrum (IR). Then it was utilized as waterproofing agent to treat wet blue leather and the effects of various parameters, such as dose of fluorinated acrylate latex, processing time, temperature, etc., on hydrophobic property of the treated crust leather were also investigated using single factor experimental method. Results showed that water contact angle (WCA) on the grain and flesh sides of the resultant leather possessed similar rule controled by dose of the CFBDH, processing time and temperature and increased with augment of those factors. The most preferable processing parameters of the above factors were individually 6% (based on the weight of the treated wet blue leather), 60 minutes and 30 °C. Thus, WCA on the grain and flesh sides of the resultant leather could attain 136° and 143°.
