      Full-color gamut mixing model constructed by four-color fibers and spinning of rotor-color yarn

      Wang Yanyan*, Xue Yuan, Chen Yourong and Chen Guofang

      Using three kinds of colored fiber and one kind of gray fiber as raw materials, a four-primary-color coupling-superposition color mixing model is constructed by the method of coupling and superposition based on the color mixing model, color change can be controlled in the range of panchromatic gamut, and the digital precision control of hue, brightness, and chrominance can be realized. Based on the three-channel NC spinning principle, the three-channel spinning mechanism of multi-channel feeding speed ratio, primary color fiber mixing ratio, and forming yarn color was established. One hundred fifty-six colors of three series of the same brightness but different hue; same hue but different brightness; and same hue but different chrominance are selected from the full-gamut color mixing model for spinning yarn and fabric; then list the HSL values of blended yarn, the technological feasibility of producing color yarn based on full-color gamut mixing model and three-channel CNC rotor spinning platform is verified.

        Bast fibre dyeing process was common practice as the value addition of most bast fibres was demanded for various commercial and household
        applications. In this research work, kusha fibre (which was extracted in our previous work) subjected to dyeing using direct, reactive, vat
        and cationic dyes for the first time. The dyeing process was performed using concentrations 0.5%, 1%& 3% (W/W) dye to fibre with MLR
        1:20. After dyeing process; performance of dyed fibre (dye absorbency measurement, colourfastness to washing, colourfastness to
        rubbing, colourfastness to light) and tensile tests were conducted. The results revealed that; K/S value of all dyed kusha fibre
        samples increases as the concentration of dyes applied increases, the colourfastness to washing of dyed fibres except the of direct
        dyes were found good, in both dry and wet rubbing fastness, reactive dyed samples have overall good rubbing fatness performance over the
        others, light fastness result shows it is good performance for all samples according to blue wool light fastness standard that exceeds 6. The
        tensile strength and elongation of dyed samples showed slight decrement in both vat and direct dyed samples; whereas, the considerable
        decrement was observed both in samples dyed with reactive and basic dyes as there is formation of covalent bond between fibre and dye
        and acid medium of processing affected the tensile property respectively.
