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.

Reshamgar, founded in 2004, designed and digitally printed clothing in Faisalabad, Pakistan. The textile industry of Pakistan is the largest manufacturer and exporter of textile goods. The textile industry became more competitive and products became homogenous. The total export of textile goods in the United States and European markets and exports are around 63 percent and the paramount contribution to gross domestic products is 6.1 percent. The company wanted to focus on service excellence and make well-built relations with distributors to maintain printing Prices per Yard (PY). This study divulges that the textile industry is the backbone of the economy of Pakistan. This sector has been facing great challenges for the last five years and has created a major gap in the economy of Pakistan. The main challenges are high inflation, high-interest competitiveness in the market, and printing ink for printing machine import from China and research has shown the company's performance with competition despite the sales and low cost per yard. It is recommended that textile industries play a requisite role in the development of challenges and barriers that are resolved on time by adopting inventive strategies. Although several challenges are uncontrolled they can be determined by well-defined policies and procedures by government institutions and textile association bodies in Pakistan.

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.
