Treatment of Polyamides Fabrics with Cyclodextrins to Improve Antimicrobial and Thermal Stability Properties~!2009-05-11~!2010-03-08~!2010-07-14~!

Abstract

Treatments of polyamide 6, Quiana and Nomex fabrics with β-Cyclodextrin(CD) or monochlorotriazinyl β-Cyclodextrin(CD-T) were investigated. Significant improvements in antimicrobial and thermal stability uniformity were observed. The colour values and fastness of the coloured fabrics to washing and perspiration were given. The untreated and treated fabrics were characterized by infrared spectroscopy (FTIR), differential thermal analysis (DTA) and thermogravimetric analysis (TGA). The changes in yellowness, moisture regain, roughness, tensile strength, elongation and antimicrobial activity have been studied. The TGA indicated that the temperature of burning T b value lies at 471 o C-472 o C for CD treated polyamide 6 while it lies at 475 o C-490 o C for CD-T treated one. This may afford the use of CD-T in treatment of polyamide 6 to attain also some heat resistance than untreated one.

“…25 Likewise, β-cyclodextrin modified with monochlorotriazine (β-CD-MCT) is fixed on the surface of cotton fabric by the paddry-curve method at a higher temperature where β-cyclodextrin enhanced the tensile strength of the treated fabric. 26 Recently, poly(cyclodextrin-cocitric acid)-grafted cotton fabric has been prepared by esterification of CD as a monomer, citric acid act as cross-linker, and sodium dihydrogen phosphate act as a initiator on a cotton fabric at a 180…”

Síntese De Zeólita Tipo Sodalita a Partir Da Cinza Volante

“…Alguns estudos investigaram o uso das ciclodextrina como auxiliar de tingimento para fibras de poliéster e poliamida (CARPIGNANO,2010;BENDAK et al, 2010) (AHANI et al, 2012;HAMDAOUI et al, 2015;KODRIC et al, 2016). Para desenvolver efetivamente um fotocatalisador de semicondutores capaz de empregar energia solar sustentável e segura, várias pré-condições precisam ser satisfeitas: (1) menor intervalo de banda para absorver uma fração maior da energia solar;…”
