Imparting Durable Ultraviolet Protection to Polyamide 6 Fabric
H. El-Sayed,A. Abou El-Kheir,L. K. El-Gabry,K. Haggag 한국섬유공학회 2019 Fibers and polymers Vol.20 No.10
Deterioration of polyamide 6 fabrics upon exposure to ultraviolet radiation for a long time is an acute dilemma. Imparting ultraviolet protection to polyamide fabrics is of prime importance from the performance and economic point ofviews. In this investigation, polyamide 6 fabrics were modified with an environmentally friendly product (sericin) in presenceor absence of crosslinking agents; namely citric acid or epichlorohydrin using pad-dry-cure technique. Topographicalinvestigation of the used sericin powder was conducted using transmission electron microscopy (TEM). The morphologicalstructure of treated as well as untreated fabrics was investigated using high resolution field emission scanning electronmicroscope (FE-SEM). The alteration in some physico-mechanical characteristics of the treated polyamide 6 fabrics; Viz. bending stiffness, burst test, degree of yellowness, and moisture regain were assessed. The treated polyamide fabrics weredyed with acid and reactive dyestuffs. The colour strength and washing fastness for dyed fabrics with both acid and reactivedyes were assessed. The photo-protection against UV light of the said fabrics were evaluated. The treated fabric exhibitedexcellent UV protection without significant discrepancy in their inherent physico-mechanical properties.

Ecofriendly Modification of Acrylic Fabrics for Enhanced Transfer Printability
Lamiaa K. El Gabry,Amira Adel Abou El-Kheir,Hanan S. El-Sayad,Madiha A. El-Kashouty 한국섬유공학회 2021 Fibers and polymers Vol.22 No.2
In this study, acrylic fabrics were given desirable properties, such as UV protection, moisture regain, sinkingperformance, lateral migration performance, hydrophilicity, and air permeability, by coating these fabrics with nanoclay,namely, nanobentonite, and its nanocomposites. The pretreated and untreated acrylic fabrics were modified with differentconcentrations of sodium polyacrylate/bentonite nanocomposites using the pad-dry-cure technique. The surfacemorphologies and elemental compositions of the treated and untreated fabrics were investigated using high-resolutionscanning electron microscopy (SEM) and dispersive X-ray spectroscopy (EDX), respectively. The particle size of the usednanobentonite was measured using transmission electron microscopy (TEM). The physical properties of the treated anduntreated fabrics were measured and compared. Moreover, the performance of the treated and untreated fabrics insublimation transfer printing with C.I. Disperse Red 60 was investigated. The color fastness properties of the printed fabricsduring washing, perspiration, and rubbing were also evaluated. The results verified that treating acrylic fabrics withnanobentonite and its nanocomposites substantially improved the physical properties, transfer printability, and color fastnessproperties of the fabrics.
