Water-based self-lubricating wet rubbing fastness improver and preparation method thereof

The invention discloses a wet rubbing fastness improver with excellent hydrophilicity and good self-lubricating performance, the wet rubbing fastness improver is formed by combining a self-made hydrophilic prepolymer and a self-lubricating functional monomer through a multi-arm bridging agent, and an experimental result shows that the water-based self-lubricating wet rubbing fastness improver has good hydrophilicity and good self-lubricating performance, and can be used as a water-based self-lubricating wet rubbing fastness improver. The material can be effectively adsorbed to the fabric surface; meanwhile, the wet friction fastness improver has good self-lubricating performance, friction can be effectively reduced in a wet state, and the wet friction grade is improved. 本发明公开了一种具有优异的亲水性和良好自润滑性能的湿摩擦牢度提升剂，该湿摩擦牢度提升剂由自制亲水性预聚体跟自润滑功能单体通过多臂桥联剂结合，实验结果表明，该水性自润滑湿摩擦牢度提升剂具有良好的亲水性，能通有效吸附到织物表面；同时，该湿摩牢度提升剂具有良好的自润滑性能，在湿态下能有效减少摩擦、提高湿摩擦等级。
