Good quality printing with reactive dyes using guar gum and biodegradable additives
Reinhold Schneider, Sonja Šostar-Turk, 2003, izvirni znanstveni članek

Opis: In printing with reactive dyes sodium alginates or synthetic thickeners are typically used as thickening agents to prevent unacceptable fabric handle. A new reactive printing process for reactive dyes on cellulosic textiles has been developed using natural thickening agents and environmental-friendly additives. Printing trials with guar gums have shown that the use of differentadditives can prevent fabric stiffness. These additives have no significant influence on rheology and colour strength but contributed to soft fabric handle even when guar gums were used as thickening agent. The use of additives and guar gum provide good quality prints with reduced wastewater pollution.

Evaluating the bending rigidity of flat textiles with the use of an Instron tensile tester
Mirosława Kocik, Witold Żurek, Izabella Krucinska, Jelka Geršak, Jan Jakubczyk, 2005, izvirni znanstveni članek

Opis: The purpose of this work is to verify the possibility of using an Instron tensile tester for evaluating those mechanical properties of flat textile fabrics which are responsible for their handle properties. A method of evaluating the bending rigidity of woven fabrics was developed. The method consists in axially compressing samples fixed at both ends and placed in a vertical position, which leads to their buckling. The bending rigidity was determined on the basis of the critical maximum force occurring at buckling, and the curvature of the buckled sample which appears as result of the action of this force. The results obtained by this method were compared with those obtained with the use of the FAST system. The good compatibility of both these methods was proved by the correlation coefficients.
