  Abstract

Silk, a renowned luxury textile with a long history, is susceptible to wrinkling and yellowing when taken and exposed to sunlight, which shortens its lifespan. To improve the wrinkle resistance and UV protection of silk fabrics, silk fabrics were treated with a wrinkle-resistant treatment using a composite finishing agent made of chitosan and polycarboxylate acid and a compound catalyst. Subsequently, tea polyphenol was applied to achieve UV protection on the wrinkle-resistant fabrics. The study investigated the factors affecting both wrinkle resistance and UV protection of the treated fabrics. The results demonstrate that the optimal anti-wrinkle finishing employs a 3% owf compound catalyst (sodium tartrate to citrate at 3:1 mass ratio) cured at 160 °C for 90 s. The best UV-resistant process utilized a tea polyphenol concentration of 6 g/L, an impregnation time of 60 min, and a temperature of 60 °C. Compared to the original fabric, the treated silk demonstrated excellent wrinkle resistance and UV protection, with a crease recovery angle of 267.1° and a UV protection factor of 111.9. Furthermore, these properties were maintained even after 20 washes. Therefore, the composite finishing process shows significant potential for extending the service life of silk fabrics.
