Design, technology and evaluation methodology of multifunctional jacquard blackout fabric for public interiors applications

Abstract

The following dissertation is based on the author's over ten years of professional experience. The author's area of interests and activities coincide with the scientific area of the work environment.
The nature of the dissertation qualifies it for the application category. The result of technological work is an innovative construction of curtain fabric with barrier properties for visible light (VIS). There is a demand for the expected research result in a well-defined area of interior furnishing of public utilities in the hotel sector and business zone (HoReCa and MICE). The work includes pioneering research on the possibility of multiplication of functions in multilayer fabrics, with their simultaneous separation and assignment to each of layers. On the other hand, a huge scientific contribution of the work is a new objective method of assessing the new generation of blackout fabrics with barrier properties resulting from the special fabric structure.
The subject of this publication is the methodology for assessing the barrier properties of blackout fabrics developed for the purpose of assessing the new construction of curtain fabric and its subsequent classification.
The authorial methodology for assessing the barrier phenomenon of curtain fabrics was developed using a designed test stand for linear tracking of the fabric structure.
The study confirmed that due to this method, the desired measurement sensitivity was achieved, which detects individual lumens and each change in the structural structure of fabrics. It has been shown that the determined barrier indicators Transmittance (Pn) and Blackout Capability (Ztk, n) calculated on the basis of the sums of intensity values describe the variability of the structure on the defined surface of the fabric in a quantitative and therefore objective way.
Both the test stand and the developed methodology of evaluating the darkening capabilities of blackout fabrics have been adapted for further implementation in industrial applications.
