Abstract
This paper reports the study of the effects of cramming motion implemented during weaving and finer weft yarns used on dyed-yarn mixed woven fabrics produced by using raw white warps and multicolored-wefts. The cramming motion was used to increase the dyed-weft yarns cover factor of fabric, and thus, to reduce the negative effect of white warp floats at the fabric face on the color attributes of fabric. The surface structure of fabric was characterized by using several key geometrical parameters that determined the resultant fabric color attributes. The effects of fabric structure and density, weft yarn count, and the introduction of black yarn on the fabric face layer on the fabric surface geometrical parameters, physical properties, as well as color attributes were investigated under the implementation of cramming motion on the fabric. The color attributes of fabrics using cramming motion and finer yarns were also compared to the fabrics without cramming motion. The experimental results indicate that the weft yarn density and cover factor of fabric face layer are increased by applying cramming motion and finer yarns for fabricating the blue-red and/or black mixed fabrics. Consequently, the fabric lightness can be further reduced for achieving a better color effect on colorful and figured woven fabrics mainly using dyed-wefts for color mixing.
Highlights
Colorful and figured woven fabrics created by using dyed-yarns are characterized by rich color variety, impressive color display, and long-lasting color performance
The result reflects that the fabric structure and density, weft yarn count, and the introduction of black yarn on the fabric face layer structure and density, weft yarn count, and the introduction of black yarn on the fabric face layer have have effects on the geometrical parameters of fabric surface, and the final color attributes of effects on the geometrical parameters of fabric surface, and the final color attributes of fabrics
Considering the weave repeat unit, key geometrical parameters were proposed for describing the geometry of fabric face layer for dyed‐yarn color mixing
Summary
Colorful and figured woven fabrics created by using dyed-yarns are characterized by rich color variety, impressive color display, and long-lasting color performance. Due to such characteristics of colorful and figured woven fabrics, this type of fabric has a wide range of applications and outstanding decorative effects. They can be commonly found in the environment, such as decorative wall hangings, home decorations, and other products. Eight kinds of dyed wefts, namely white, black, vermillion, yellow, green, blue, Prussian blue and magenta, together with warps in a dark deep green color, were suggested for producing high-quality colorful silk textiles
