The difference in dyeability between C. I. Reactive Orange 16(O-16) and C. I. Blue 4(B-4) was found in this experiment. Initial dyeing rates were increased and the amount of dye on the fabric at equilibrium was decreased with temperature like other ordinary dyeing processes. Activation entropy(ΔS?) was decreased because of loose bonding between dyestuffs and fiber molecules at transition state. It can be clarified that the entire reaction is exothermic and the number of molecular species at transition state becomes greater from decrease in activationenthalpy(ΔH?) and the increase in activation free energy(ΔG?) with temperature, respectively. The amount on the fabric and dyeing rate of B-4 with rigid anthraquinone and triazibyl structure are less and slower than those of O-16.

現 生絲檢査規則 中 纖度偏差檢査項目에 관하여 檢討한 結果 약간의 矛盾點을 發見하였으므로 이를 지적하고 그 改善策을 設定하였다. 1. 現 纖度偏差檢査는 平均纖度가 50~69 denier에 標準偏差는 5.80以下, 4.61 以上일 때 A格으로 定하고 있으나 平均纖度 50 denier인 경우의 標準偏差 5.80과 平均纖度 69 denier인 경우의 標準差 5.80과는 同一分布라 할 수 없다. 2. C.V로 換算하여 볼 때 2A格의 C.V가 A格의 C.V보다 작아야 하는데 現 纖度檢査規定은 70denier 의 1A格의 C.V換算値는 9.00이며, 69denier의 A格의 C.V換算値는 8.41로서의 70denier 2A格이 69denier의 A格보다 變異의 分散이 크게 나타나는 矛盾點을 보였다. 3. 生絲의 纖度偏差檢査數値도 平均値가 다른 Sample끼리의 優劣을 나타내는 數値이며 이 數値로서 等級을 決定하기 때문에 標準偏差에 의하여 檢査할 것이 아니라 C. V에 의하여 檢査하여야 한다. 4. 33 denier 以上의 生絲에서 각 等級別로 볼 때 6A格에서 下位格으로 감에 따라 變異폭(變異係數)을 약간씩 크게 하였으나 곳에 따라 一貫性을 잃고 있으며 그리고 同一等級에서 纖度變化에 따른 變異係數數値의 變化도 같은 경향이므로 等級間 및 纖度間의 數値調整을 要한다. 5. 34 denier 以上에서는 標準偏差數 値를 代入하기 때문에 同一等級에서 平均纖度가 굵어짐에 따라 標準偏差數値를 크게 하였으나 C. V로 換算하여 보면 大同小異하므로 纖度變化에 따른 C. V數値를 달리 할 필요가 없다. 6. 以上의 1.2.3.4.5項의 矛盾點을 是正하기 위하여 是正하기 위하여 C.V에 의한 檢査方式을 導入하고 33denier 以上에서 각 纖度間과 각 等級間의 均衡을 바로 잡으며 또 34 denier 以上에서 각 等級間의 間隔을 바로 잡기 위하여 曲線回歸公式을 導入하여 調整할 必要가 있다. 7. 生絲檢査에서 纖度偏差檢査表를 다음과 같이 改正實施함이 보다 妥當하다. The study was carried out to suggest on opinion of the standardization of size deviation in the existing raw silk testing method. 1. The present grade A of size deviation stipulates 4.61 to 5.80 of standard deviation for 50 to 69 denier of mean value, however, the 5.80 standard deviation with the mean values of 50 and 69 denier belong to different distribution. 2. It is reasonable that the variation coefficients of grade 2A should be lower than that of grade A. However, the present testing method shows larger variation in grade 2A than in grade A. This is illustrated 9.00 for 69 denier in grade 2A and 8.41 for 70 denier in grade A. 3. The size deviation value compares the quality of raw silk with different mean value. Therefore, the standard deviation is recommended to be replaced by the C.V. value in determining the grade of silk. 4. The C.V. have a tendency to increase with lower grades below 6A for the size deviation below 33 denier with some inconsistencies. The figures should be adjusted so that the C.V. inconsistencies size deviation below 33 denier will be corrected. 5. The standard deviation increases with size under the same grade for the size deviations above 33 denier, however, the C.V. does not vary greatly with size deviation. 6. To rectify the above-mentioned inconsistencies the C.V. conversion and curvilinear regresion correction is recommended to improve the present silk testing method 7. The table of size deviation standard are as follows: Suggested standard of size deviation, unit: C.V. Value

Dyeing kinetics of C. I. Reactive Orange 16 on silk fabric was found in this experiment. Initial dyeing rates were increased and the amount of dye on the fabric at equilibrium was decreased with temperature likewise other ordinary dyeing processes. Activation entropy(ΔS*) was decreased because of loose bonding between dyestufffs and fiber molecules at transition state. It can be clarified that the entire reaction is exothermic and becomes unstable form the increase and decrease in activation free energy(ΔG*) and enthalpy(ΔH*) with temperature, respectively.
