异色夹纬真丝交织装饰织物的光透射特性
Light transmission characteristics of interwoven decorative fabrics made of silk with hidden weft of different colors
摘要
Abstract
Curtains are an important part of interior decorative fabrics.Selecting the appropriate products can not only safeguard the seclusion of indoor individuals,but also produce a unique illumination and shading effect.With the improvement of people's quality of life,they are no longer limited to using curtains with a high shading coefficient.People1 s needs for indoor light will change at any time because each room has a different function.The requirement for shade in ornamental textiles also differs,thus additional shade is not preferable.To meet people's needs,researchers and scholars at home and abroad have in-depth research on decorative fabrics.Currently,their primary objective is to enhance the fabric's shading coefficient.Few studies have been conducted on the color temperature and color rendering property of the transmitted light. The main purpose of this paper was to investigate the different transmitted light effects of a light source through a fabric.Multi-layer structured fabrics were woven by interweaving silk and polyester,with different colored yarns as the middle weft.Subsequently,a spectrophotometer was used to test the transmittance of fabrics in the visible range and to study the effect of fabrics on transmittance and shading coefficient.The color temperature of the transmitted light was calculated,and the color temperature was used to describe the color of the transmitted light.To examine the influence of transmitted light on the hue of indoor items,the color saturation and color rendering performance of various fabric transmitted light were compared by using the IES TM-30 color rendering evaluation index.The findings indicate that the color of the hidden weft in multilayer-structured silk fabrics has great influence on light transmittance.As the L*of the yarn decreases,the fabric's shading coefficient increases,spanning from 75.98％to 97.72％.By altering the color of the hidden weft,one can effectively regulate the color temperature.When the spectral power distribution of the transmitted light of the fabric is more in the short wave,its color temperature is higher;when the spectral power distribution of the transmitted light is more in the long wave,the color temperature is lower.Fabrics containing white and black wefts have the best color rendering performance with Rf and Rgreaching 100.The Rf of transmitted light of fabrics containing orange,yellow,cyan and blue weft yarns exceeds 80.The transmitted light of fabrics containing orange and cyan weft yarns provides high color saturation;the transmitted light of fabrics containing yellow and blue weft yarns has low color saturation.It can be seen that the colored weft can make the transmitted light of fabrics with different characteristics.The results of this study can provide theoretical reference for weaving decorative fabrics with different transmitted light effects.关键词
