SYNTHESIS AND CHARACTERISTICS OF SYNTHESIS AND CHARACTERISTICS OF THIOPHENE BASED MONOAZO DISPERSE DYES ON NYLON 6.6 FABRIC
Bibliographic record
Abstract
A series of monoazo disperse dyes has been prepared by diazotizing 2-amino-4(-4chlorophenylcarbamoyl)-5-methyl-thiophene-3- carboxylic acid ethylester and coupling with N, Nbis (2-cynoethyl) aniline, 3-acetylamino-N,N-diethylaniline and 3-hydroxyl-N,N-dimethyl aniline. The monoazo disperse dyes were characterized by infra red spectra studies. Visible absorption spectra of the dyes were examined in various solvents. The electronic absorption spectra covers a λmax range of 550-650 nm at uniformly high absorption intensity between 2.3 × 10 4 - 9.2 × 10 4 l mol -1 cm -1 . These dyes were applied at 5 % depth on nylon 6.6 fabrics and gave bright intense hues of purple and orange. The colour parameters of the dyed fabrics were measured and the dyes have excellent exhaustion between 79-92 % for nylon 6.6 fabrics, more intense and of very good wash fastness property on nylon 6.6 fabrics. The remarkable degree of levelness and brightness after washing is indicative of good penetration and excellent affinity of these dyes for the nylon 6.6 fabric.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
