Functional finishing of cationized cotton fabrics using Maillard reaction products of polyglutamic acid and glucose
摘要
Abstract
To address the issues of bacterial growth and oxidative yellowing in cotton fabrics,Maillard re-action products(MRPs)of biobased polyglutamic acid and glucose for the functional finishing of cation-ized cotton fabrics,aiming to achieve excellent antibacterial and antioxidant properties.Initially,cotton fabrics are cationized using 3-chloro-2-hydroxypropyltrimethyl ammonium chloride(CHPTAC).Subse-quently,the cationized fabrics are treated with MRPs through an impregnation method.The results indicate that CHPTAC treatment introduces cationic groups to the cotton fabric,significantly enhancing the adsorp-tion of MRPs.The optimal conditions for MRPs treatment are 90 oC,120 min,pH 7,and a polyglutamic ac-id/glucose concentration of 60 g/L.Under these conditions,the treated cotton fabrics exhibit a dark brown color with a K/S value of up to 6.5.They achieve grade 5 in rub fastness and color change fastness,al-though light fastness still requires improvement.The treated fabrics demonstrate excellent bioactivity,with antibacterial and antioxidant activities exceeding 95%.However,the durability of the bioactivity is relative-ly weak and needs further enhancement.Additionally,the treated cotton fabrics show improved UV shield-ing properties,reducing UVA and UVB transmittance to below 3%.关键词
