Poly (vinylcaprolactam)-based Microgels to Improve Gloss Properties of Different Natural Fibres

Abstract

Three different thermo-sensitive microgels obtained by the copolymerisation of vinylcaprolactam) (VCL) and various monomers (vinylimidazole(VIm), acetoacetoxyethyl methacrylate (AAEM) and itaconic acid(IA)) are used to coat different fibre surfaces. Two different pHs and two different temperatures, 25°C and 50°C respectively are chosen for the deposition of the microgels. The scanning electron microscopy of the treated fibre shows good distribution of the particles onto the fibres especially at increasing temperatures. The gloss index for the treated fibres has been measured, and showed that it may be controlled for all of the fibres with the treatment parameters (pH and temperature) and the microgel structure.

A review on the Development of Innovative Capabilities in the Textile Finishing of Natural Fibers

“…Nanotechnology application can economically cover the properties and values of textile processing and products. The use of nanotechnology allows textiles come to be multifunctional and crop fabrics with special functions, including antibacterial, [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] animal retardant, [20] UV protection, [21][22][23] dyeing and printing, [24,25] easy-clean, [26][27][28][29][30][31] water and stain repellent, [32][33][34][35] flame retardant, [36,37] thermo-regulating, [38][39][40][41][42][43] odor and gloss properties, [44][45][46] adsorption of metals and air pollutions, [47][48][49][50]…”

Core–shell titanium@silica nanoparticles impregnating in poly (itaconic acid)/poly (N-isopropylacrylamide) microgel for multifunctional cellulosic fabrics

“…Cellulose is one of the natural organic polymers. Cellulosic fabrics have been functionalized to add properties such as flame retardancy [1][2][3][4][5][6][7], water/oil repellence [8][9][10][11], antimicrobial [12][13][14][15][16][17], metal adsorption [18][19][20][21][22], gloss properties [23], rodent repellence [24], anti-UV protection [10,25], Stimuli-responsiveness to temperature, and pH [13,26], heat storage, [27][28][29][30] via a variety of methods, including polymeric material deposition and/or infiltration [31][32][33][34][35][36][37], and nano-coating methods [4,20,21,[37][38][39][40][41].…”

Environmentally Friendly Inorganic Materials for Anti-flammable Cotton Fabrics

“…Although LBL depends on parameters such as polyelectrolyte, temperature and pH chemistry, the procedure is not limited to material surface size, shape and topography, making the technique suitable for customising the surface properties of nonplanar textile fabrics. [9][10][11][12][13][14][15] The LBL deposition of clay and nanoparticles with polyethylene (BPEI) branched to cotton fabrics by Grunlan and co-workers has thoroughly studied to produce flammable multi-layer coatings of environmentally friendly, all-polymer nanocovariation that can extinct the fires of cotton materials. [16] The use of LBL technology to alter the surfaces of textile fabrics and fibres has been widely studied in recent years but there is still little understanding of the process as a whole.…”
