Study on Hydrophilic Finish and Performance of Polypropylene Spun-Bonded Nonwovens

Abstract:

A new kind of polypropylene spun-bonded nonwovens (PSN) with excellent hydrophilic property was developed after finished with S 6237 hydrophilic agent. The infiltration time (IT) and the runoff (RO) were tested to evaluate the hydrophilicity of the finished PSN. The impacts of different agent concentrations, drying temperatures and drying time on hydrophilicity were investigated and PSN before and after finished were compared concerning softness, air penetrability, moisture regain and stretch performance. The results show that the optimum technological condition for the hydrophilicity is agent concentration: 4 %, drying time: 30s and drying temperatures: 120 °C, and the IT and the RO for the first time are 1.82s and 1.8% respectively. Softness and air penetrability of the finished PSN were improved significantly but mechanical performance was merely decrease a little.
