Study on novel eco-friendly anti-creasing agents for natural silk fabric

Three novel eco-friendly anti-creasing agents have been designed and synthesized. The natural silk fabrics treated with them exhibit higher wrinkle recovery degree, strength retention rate and whiteness than those finished with 1,2,3,4-butane tetracarboxylic acid （BTCA）. The washing durability of the fabrics treated with the synthesized compounds and BTCA is similar. The chlorine atom, the carboxyl and the s-triazine ring in the synthesized structures and the surface roughness of the silk fabric are all contributive to the imorovement of the crease resistance of silk.
