“…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.

“…We will use the theory developed in our previous paper [ 11 ] for predicting the goniophotometric curves for knitted fabrics made from monofilament yarns to simulate the curves in order to investigate the effects of fabric parameters. The relative intensity is calculated as the amount of light reflected per unit area of fabrics, which has been projected by the incident light of unity intensity at a point p~:…”

“…In our previous work [ 11 ], we proposed a mathematical model that predicts the distribution curves of specularly reflected light from single-jersey knitted fabrics made from monofilament yarns, and we verified the model experimentally. We obtained good agreement between the goniophotometric curves calculated from the model and experimentally measured curves of straight rods and single-jersey fabrics knitted from monofilament yarns.…”

This paper is concerned with the prediction of goniophotometric curves (distribution curves of specularly reflected light) based on our mathematical model developed earlier for single-jersey knitted fabrics made from monofilament yarns. The theory is extended to include fabrics from multifilament yarns. Four physical and optical parameters related to the fabric and the light source are investigated: fiber refractive index, yarn cross section, incident light angle, and fiber ellipticity. Their effects on the goniophotometric curves and luster index of knitted fabrics are determined. In addition, the great difference is high lighted between light reflected from knitted fabrics and light received by the goniopho tometer.

“…[1][2][3] These works focused on the dye/ light interaction, taking into account independent variables, such as the coefficient of dye absorption, refractive indexes of the fibers, the effect of color on the geometry of the fabric and yarn and the distribution of the dye within the fiber. 4,5 Theoretical models have been developed and expanded to apply to yarn and fabric, 6,7 taking into consideration the factors of dye concentration, the ratio of refractive indexes, 8,9 fiber fineness, [10][11][12] the structure of the textile substrate [13][14][15][16] and dye distribution. 17,18 However, the textile/light interaction needs to be further studied for enhancing the UV protection of the textile.…”

In this study, a model was set up for simulating the effects of varying fiber cross-sectional shapes on ultraviolet protection of fibers. The fiber diameter and fiber type were also involved in the model setting. Experiments of diffuse reflectance spectra measurement on natural (wool, cotton, silk), regenerated (bamboo viscose) and synthetic (polyester, nylon) fibers were conducted to verify the model predicted results. When a more complex shape was assumed as the fiber cross-section for model calculation, the predicted results have a better agreement with the actual results. The effects on ultraviolet absorption from fibers with different cross-sectional shapes were investigated at a single fiber, fiber bundle and yarn levels. With the same material, when the fiber cross-sectional area and the areal coverage of a single fiber were constant, the triangular shape had the lowest ultraviolet transmittance and the highest ultraviolet reflectance for a single fiber and also for a fiber bundle. The difference of fiber cross-sectional shapes was also significant in the ultraviolet protection of a single yarn.
