Abstract

A long-lasting water-repellent textile treatment process using a curable polydimethylsiloxane (PDMS)-containing polyurethane (PU) system includes the steps of mixing a di-isocyanate with a PDMS-containing material, and reacting the di-isocyanate with the PDMS-containing material to form an NCO-terminated PDMS-containing PU system. The treatment process obtains a long-lasting water-repellent textile, which overcomes the shortcomings in hand feel, washing durability, and breathability of the conventional water-repellent textile, while having the advantages of low cost and of being an environmentally friendly process, while also providing useful and practical industrial applications.
