Synthesis and application of cationic biological protein derivative fixing agent
摘要
Abstract
A quaternary ammonium salt cationic biological protein derivative fixing agent (WLS- 20) was prepared using waste feather protein and self- made reactive cationic crosslinking modification agent WLS as raw materials, which was applied in the fixation post- treatment of reactive dyed cotton fabric. Using white cloth staining degree (K/S value) of soaping post- treatment and soaping fastness as evaluation indexes, the ef⁃fects of mass ratio of abandoned feather protein and WLS, alkali agent dosage, reaction temperature and reac⁃tion time on the fixation result were investigated. The optimum synthesis conditions of fixing agent WLS- 20 was determined: the mass ratio of feather protein and WLS was 1∶16, sodium hydroxide dosage was 3% (on the mass of WLS), reacted at 65 ℃ for 4 h. The structure and performance of the agent was characterized. The results showed that the WLS- 20 had absorbance to UV light, and the maximum absorption wavelength is 195 nm. WLS- 20 additives dosage and absorbance had the best linear relationship under the maximum ab⁃sorption wavelength. WLS- 20 synthesized under the optimum conditions could reduce the white cloth stain⁃ing during soaping, and effectively improved the color fastness to washing and crocking of cotton fabric.关键词
