AB - In this study, natural plant pectin was extracted from the stem bark of  Hibiscus mutabilis and utilized to finish knitted cashmere fabrics. The  performance differences between the fabrics before and after finishing were  investigated. The results demonstrate that the extraction solution,  comprising hibiscus stem bark tartaric acid at a pH of 2, extraction time  of 90 minutes, and a material-liquid ratio of 1/30, yielded pectin at a  yield of up to 13.24%. This yield is not as high as that of tartaric acid.  Following the finishing of the knitted cashmere fabric with hibiscus  pectin, a notable enhancement in the fabric's antibacterial and UV  properties was observed. Following the application of a 7.5% hibiscus pectin  solution, the transmission rate of UV light with a wavelength of less than  290 nm exhibited a tendency towards zero, while the ultraviolet protection  factor value reached 43. Furthermore, the bacterial inhibition rate of  Staphylococcus aureus was observed to reach 94.571%.
