The Effects On Anti-stain Properties Of Surfactants On Spandex Blend-fabric And The Interactions With Dyes

This paper explores the influences of Vinyl polymer and six agents, such as 1815, NaBH4+NaHSO3, CMC,Isopropanol, Anti-oil Additives CB and AEO-9 phosphate, on staining behavior of polyester and Spandex during Restore Cleaning, using an orthogonal and single factor experimental approach. In addition, the interaction between dyes and agents is investigated through UV-Vis absorption spectroscopic analysis.Our study shows that during Restore Cleaning process, 1) 1815 and NaBH4+NaHSO3 can greatly reduce the staining of dyes on polyester and spandex. 2) MAM-DMDA could prevent staining to the two fibers, but it has Little effect for the Anti-stain with other agents. 3) The mixture of Isopropanol and CMC or Anti-oil Additives CB and AEO-9 phosphate have good effects on preventing staining for the two fibers. 4) during soaping process, auxiliary A (PDMDA/1815/NaBH4+NaHSO3) could prevent the dye staining to the cotton effectively, but will increase the staining to spandex.It also shows that 1) it has strong adsorption between MAM-DMDA and disperse dyes. 2) the influence of mixed surfactants to the absorptions of dyes is related to the types of surfactants and dyes.
