Effect of the chemical modification of cotton fabric with propane sultone and through grafting with acrylonitrile on the dyeability with basic dyes

Abstract

The sulfonated cotton fabrics (sulfur content: 0–0.52%), obtained by the treatment with propane sultone, were subjected to graft copolymerization with acrylonitrile. The values of the % graft of the sulfonated cotton fabrics were higher than those of untreated cotton fabrics. The sulfur contents of the sulfonated cotton fabrics, however, affected little the % graft. The sulfonated and grafted cotton fabrics absorbed basic dyes, Methylene Blue, Diamond Green, and Cathilon Red. The color fastness of these dyes towards light from a Xenon lamp and towards ultraviolet radiation was significantly improved by the introduction of polyacrylonitrile onto cotton.

Investigating the properties of cotton fabric coating with polyacrylic rubber and using this polyacrylic rubber coated fabric as an alternative to polyethylene bags

“…Some authors have studied on finishing treatment of cotton fabric by utilizing PAR in the presence of NaH 2 PO 4 as a catalyst [7]. A variety of surface finishing techniques, ranging from layer-by-layer (LBL) assembly [8][9], chemical grafting, to propane sultone chemical grafting, were used [10][11]. Many authors have also been studied on sol-gel coating for coating [12][13][14] to make functional textiles with flame retardant [15], antibacterial [16], UV protective and self-cleaning properties [17], and water repellent [18].…”

Characterization of Water Repellent and Flame Retardant Finished Cotton Canvas Fabric for Bivouac Tents

“…[2][3][4] Finishing is the key way to impart functional properties in textiles, as it is the final phase and a crucial step in the production process. Layer-by-layer (LBL) assembly, 5,6 chemical grafting, 7,8 and the sol-gel process [9][10][11] have all been used to create functional textiles with antibacterial, 12 flame retardant, 13 water repellent, 14 ultraviolet (UV) protection, or self-cleaning qualities. 15,16 However, most of the flame retardant chemicals used in sol-gel procedures are hydrophilic, making them susceptible to fouling and water, resulting in the loss of flame retardancy and a reduction in the mechanical qualities of substrates after many laundering cycles.…”

“…17 results for flammability are comparatively not better than other techniques such sol-gel and the use of primary and synergistic flame retardants. [9][10][11]13 The other, more promising option [5][6][7][8][9][10][11][12][13][14][15][16] is to add water repellency to flame retardant coatings. [19][20][21][22] Flame retardants are chemicals added to materials to prevent combustion and slow the spread of fire.…”
