“…The further demonstration was carried out on a standard dress form by using the grey cotton fabrics and the standard mannequins, scientifically verifying that the structure segmentation of the fourth line is the most beautiful. It is worth mentioning that the cotton is the most popular fabric for the garment manufacture (Chen, Qu, Yang and He, 2014; Chen, Qu, Zhao and He, 2014; He et al , 2015). In the practice of the industrial fashion design, the cotton grey fabrics are usually set as the control for the standardization of the examination on the garment style.…”

Purpose The purpose of this paper is to develop a novel method for establishing the mathematical link between the restored Hogarth curve and the golden ratio, and to advance the potential application of the Hogarth curves in standardization of the garment pattern design by using this method. Design/methodology/approach The Hogarth curve was fully restored by using the plant design system (PDS) software package and divided the restored curve into two fragments based on the intersection point between the curve and the straight line joining the curve endpoints. The ratios between two fragments of curves and straight lines were calculated and compared with the golden ratio, respectively, which was set as a normalized value. The potential application of the restored Hogarth curves in the normalization of the garment pattern design was therefore studied by using the standard mannequins. Findings The ratio in the most beautiful curve, i.e., the fourth Hogarth curve, was found to be infinitely approaching to the golden ratio. Furthermore, the incorporation of the Hogarth curves into the garment pattern design demonstrated that the fourth Hogarth curve was the most aesthetic line. Originality/value This work offered a novel method for bridging the gaps between arts and maths, i.e., the mathematical relation between the Hogarth curves and the golden ratio. Such a method will provide the protocol to promote the potential applications of the Hogarth curves in the garment pattern design and the human body decoration.

“…One of the most used additives is fluorescent brighteners (FWAs), which are also used for pulp whitening in the paper industry and cotton industry due to the superior whitening performance and relatively low cost (Konstantinova et al 1999;Hörsch et al 2003;Lee et al 2005;Fan et al 2007;Jung and Kang 2013). Even so, the primary disadvantages of FWAs are their poor stability in long-term irradiation, low yellowing point, and sensitivity to sunlight (Konstantinova et al 1999;Chen et al 2014). To overcome the draw-backs of FWAs, numerous researchers have introduced fluorescent molecules to improve the photostability via steric hindrance in polymerization systems (Hussain et al 2009;Saeed et al 2014).…”

3-Aminopropyl-trimethoxysilane was introduced into bis-triazinyl amino-stilbene through the condensation reaction to obtain fluorescent whitening agents (FWAs) having excellent photo-stability. Tetraethoxysilane was hydrolyzed and combined with FWAs through in situ polymerization to obtain nanosilica-loaded yellowing inhibitors (SiO2–FWAs). Ultraviolet (UV) spectroscopy showed that the ratios of the trans-isomer structure in FWAs after 3 h of UV irradiation was 5.41 times higher than those of the cis-isomer. Moreover, the absorption intensity in the UV region was increased distinctly after nano-silica loading. Fluorescence spectroscopy revealed that the fluorescence of SiO2–FWAs was more intense than that of FWAs. In addition, the fluorescence quantum yield of SiO2–FWAs reached 0.416, whereas that of the default FWAs was only 0.279. UV-aging test results showed that SiO2–FWAs can improve the initial whiteness and anti-yellowing performance of paper made from high-yield pulp (HYP). These results indicated that the as-prepared SiO2–FWAs not only exhibited more excellent UV absorption and fluorescence emission properties, but it also exerted better whitening and anti-yellowing effects on high-yield pulp paper than the default FWAs. The enhanced performance of SiO2–FWAs can be ascribed to the synergy between the excellent UV-scattering effect of nanosilica and the fluorescent whitening property of FWAs.

“…19 In modern times, such agents have adopted the synonymous terms optical brighteners and fluorescent whitening agents, with their primary purpose being the absorption of ultraviolet (UV) light and the fluorescence of blue light. [22][23][24] Combining a blue dye that acts as an optical brightener with an SRP yields a material that holds great promise for application in advanced laundry applications as an active component that can both prevent fabric staining and discolouration, and impart brilliance to white fabrics. However, the permanent and extensive coloration of polymers that inherently lack repeat unit functionality is challenging.…”
