“…In the earlier studies conducted [19–21], the focus was on the analysis of the effect of a specific wet pick‐up of the sample on its colour. However, in the actual situation of the present study, especially during the chemical processing of the textile materials, and because the water content in them varies, different levels of wet pick‐up were considered.…”

In the present study, the effect of various levels of bulk and free water content and its distribution on the colour of cotton fabrics dyed with direct dyes and their combinations were analysed. Twill and plain structures with two different parameters of fabric construction were chosen. The dyed samples were adjusted to different levels of wet pick‐up, with water ranging from 50% to 125% on the bone dry weight of the fabric (odwf) to achieve various levels of bulk water content. Further, the residual moisture content of the samples was adjusted to 40–10% odwf by means of hot air drying at different temperatures to obtain different levels of free water content and its distribution. For the assessment of colour and its comparison, the parameters ΣK/S and values were used. In order to bring out the true effect of moisture distribution and fabric structure, normalisation of dye uptake in the fabric based on weight and area were considered, respectively. The plain structures show a higher increase in colour than the twill structures when the bulk water content increases. At the same time, the fabric structures do not play a significant role, with increase in colour attributable to change in drying temperature. The findings reveal that the bulk water content, drying temperature and fabric geometry affects the colour of the fabric significantly.

“…The existing mathematical models are classified into light fluxes models [4,5,6], fibers pileup models [7,8], fibers pileup-pores models [9,10] and ray trace models [11,12]. Among which, the two fluxes Kubelka-Munk model [4] has been most widely used, especially in the field of color technology.…”

Abstract. In this paper, existing models of fabric's optical behaviors are classified and estimated briefly. Then, basing on the optical theories, this paper abstracts the commonness of fabric's optical behaviors and put forward an improved model of them, which includes a physical model and its corresponding mathematical model. The physical model describes the light falling on fabrics splits into six components, which compose another four components. The ten light components divided by the incident light yields ten light component parameters, which are functions of the wavelength. The mathematical model connects the ten light component parameters and gives formulas to calculate them. Thus, the light component parameters are connected with the basic optical parameters and structural parameters of fabric. This improved model provides a fundamental and theoretical guide for studying fabric's optical properties systematically, which has been proved to be effective in solving some problems related fabric optical properties.

“…The advantages of NCCS fiber in deep‐coloring could be simply, low‐cost and applicable in scaled production, compared to other conventional methods . In 1980s, Allen and Goldfinger proposed a mathematical and geometry model based on the “pile of plates” for analyzing the color of fabrics by assuming that each “plate” consists of a parallel array of isotropic cylinder of equal diameter and forming uniformly dye distribution as well as surrounded by transparent and continuous Media. The model proved to be effective as well as that of dyed circular fibers by taking the ringdyeing phenomenon and internal scattering into consideration.…”

The effects of noncircular cross‐section (NCCS) poly ethylene terephthalate (PET) filaments and its shape factor on deep‐black‐coloring of dyed fabrics were investigated by comparing to that of the circular cross‐section PET ones. Indexes such as K/S, L* and Integ values were used for characterizing the deep‐black‐coloring effect on fabrics. The results indicated that fabrics made with NCCS PET filaments exhibited good deep‐black‐coloring effects. The calculated shape factor of the NCCS PET fiber had a significant correlation with the degree of deep‐black‐coloring exhibited by the fabric made from the fibers. A qualitative optical analysis of the NCCS PET fibers was carried out to explain the causes of the deep‐coloring of the NCCS fibers. This analysis implies that the contours of the NCCS fiber composed of surfaces with varied curvature increase the scattering of light by lowering specular reflection and increasing interior reflected and refracted light. This, in turn, strengthens the deep‐coloring effect. © 2013 Wiley Periodicals, Inc. Col Res Appl, 39, 511–518, 2014
