Abstract
In this research work an objective method for evaluating the levelness (L) of coloured textile materials by spectrophotometric measurements is reported. Colour levelness is actually a description of the uniformity of colour shade in different places of the fabric. Thus, we use three different fabrics namely, wool, polyester and wool/polyester blend (65/35%), firstly these fabrics are treated with different uv/ozone exposure times continued for one hour exposure, followed by dyeing separately with three different dye classes; reactive, direct and acid. The colour strength (K/S) and colour difference ?E after exposing of the treated dyed samples to artificial day light are measured spectrophoto-metrically. The results of these measurements are statistically correlated with the levelness (L), relative standard deviation Sr (?), and the unlevelness (U). The obtained results showed that the dyeability, L parameter, U parameter and ?E values are greatly depend on the dye class used, fabric nature, and type of treatment applied. Where as these parameters reflect the effect of homogeneity of dye distribution on the fabric which decreases the colour fading of the dyed samples under test. Where uv/ozone exposure leads to the increase in the amorphousity of the exposed samples especially at the end of exposure leading to an increase in the exhaustion and diffusion of the dye inside the fabric pores besides, to its effect on districting the dye accumulation and hence increases the levelness of dyeing.

Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
