    Effect of cationization on inkjet printing properties of cotton fabrics
    (AATCC, 2004-06) Hauser, Peter Jacob; Parrillo-Chapman, Lisa Parillo; Donaldson, Alan; Kanık, Mehmet; Uludağ Üniversitesi/Mühendislik Fakültesi/Tekstil Mühendisliği Bölümü.; 6602352034
    The objective of this research was to investigate the effect of cationization on inkjet printing quality. A cotton woven fabric was cationized by pretreatment with 2,3-epoxypropyl-trimethylammonium chloride (EPTAC) using a cold pad-batch method. For the prints, four reactive primary colors (CMYK) were used on both untreated and cationized cotton. The effects of thickener concentration, alkali concentration, and print resolution were investigated. Color yields, outline sharpness, colorimetric properties, fastness properties, staining of the white grounds, and penetration behavior were evaluated. It was found that inkjet printing with reactive dyes on cationized cotton has good potential for providing a cost effective and more environmentally friendly printing method using less dye, less thickener, and less alkali while maintaining high outline sharpness.

    Ink-jet printing of cationised cotton using reactive inks
    (Wiley, 2003) Hauser, Peter Jacob; Kanık, Mehmet; Uludağ Üniversitesi/Mühendislik Fakültesi/Tekstil Mühendisliği Bölümü.
    The ink-jet printing properties of cotton cationised with 2,3-epoxypropyltrimethylammonium chloride have been studied. Cyan, magenta, yellow and black reactive inks were used to print untreated and cationised cotton fabrics. The effect of cationic reagent concentration, steaming time, ink (colour) and print resolution were investigated, together with possible differences between the behaviour of the four inks. Colour yields, staining of the white grounds, penetration behaviour, print quality and fastness properties were evaluated.

    Printing cationized cotton with direct dyes
    (Sage Publications, 2004-01) Hauser, Peter Jacob; Kanık, Mehmet; Uludağ Üniversitesi/Mühendislik Fakültesi/Tekstil Mühendisliği Bölümü.; 6602352034
    This paper investigates improved direct dye printing of cotton by cationization. For the cationization, a 100% cotton woven fabric is pretreated with 2,3-epoxypropyltrimethyl-ammonium chloride by a cold pad-batch method. All printing conditions are constant, and four different direct dyes are used to print both unmodified and cationized cotton fabrics. The effects of cationic reagent concentration, steaming time, dye concentration, color yields, colorimetric properties, fastness properties, staining of,the white ground, and penetration behavior are evaluated. This research reveals that printing with direct dyes on cationic cotton is a very simple, cost effective printing method with high wet fastness properties.
