    目的 緩和弾性率が時間のべき乗に比例するべき法則粘弾性固体を定ひずみε1まで定速伸張し, 引続きε1の状態にtr時間保持させる.その後の伸張弾性回復挙動を線形および非線形模型を用いて予測する.ただし, 線形模型にはBoltzmannの式を, 非線形模型にはSchaperyの時間-ひずみ換算型の式を用いる.2種類のポチエチレンフィルムについて伸長回復実験を行い, 理論計算と比較する.
    結果 (1) 線形模型の除重時の弾性回復率 (U.E.R.) は, tr=0でε1に依らず一定となり, tr>0でε1の増加とともに増す.非線形模型のU.E.R.は, 線形模型のU.E.R.より小さく, その差はε1が大きいほど大きい.U.E.R.はtrに関し指数関数的に減少する.応力緩和が著しく非線形性の強いべき法則体ほど, U.E.R.は小さい.U.E.R.の実験結果は, 非線形模型の予測と定性的に類似している.
    (2) 除重終了後の遅延弾性回復率 (D.E.R.) は線形模型についてのみ計算できる.模型のD.E.R.は, trは, tr=0でε1に依らず一定となり, tr>0でε1の増加とともに減少する.応力緩和の著しいべき法則体ほど, 遅延回復速度は高くD.E.R.は大きくなる.これらの線形模型の予測に反し, D.E.R.の実験結果は著しい非線形効果を示し, 線形理論と一致しない.

    The labor cost and energy cost account for 5060% and 1015% of the total cost of dyeing and finishing process respectively . The sum of the two costs amounts to 6075%. Because an increase of the labor and petroleum cost reluctantly raise the dyeing and finishing cost, it is more needed for an advanced production systems to save both labor and energy . An attempt has been made to develope an unattended and energy-saving system in the dyeing process.
    The results obtained in the plant of 8, 000 Kg/day, i.e., about 60 batches per day in productivity are :
    (1) Labor saving :
    i) The number of operators attending to 10 sets of dyeing machines and weighing dyestuffs was reduced from 24 to 4.
    ii) Labor productivity of dyeing process including an auxiliary process was increased by about 3 times.
    (2) Energy and resources saving :
    i) The consumption of steam was reduced to about 1/3.
    ii) The consumption of water was reduced also to about 1/3.
    iii) The consumption of dyestuffs and chemicals was reduced by about 10%.

    The diffusion coefficients of C.I. Disperse Red 17 into poly (ethylene terephthalate) films were measured in the mixture of solvents by the film-roll method. Following results were obtained.
    (1) The relations of the diffusion coefficients and the molar fraction were remarkably dependent on the combination of the solvents, and were divided into two types, i.e., . (a) the diffusion coefficients which decrease or increase with increasing the molar fraction of a component, and (b) the diffusion coefficients which increase with increasing the molar fraction to a maximum and then decrease.
    (2) The diffussion coefficients correlate to the values of T1 and increase with decreasing the values, T1.

    The distribution of the life of girdles has been found to be well simulated to the Weibull's curve. The shape factor m and scale parameter t'0 of the curves in the different cases under some conditions of tests are shown in the following table.
    (1) Column 1 shows that the samples tend to deteriorate their performances even at the beginning of the utilization.
    (2) Column 2 shows that hard type samples are more deteriorated than soft ones.
    (3) Column 3 shows that the samples washed in a weak alkaline detergent solution are more deteriorated than those washed in the neutral detergent solution.
    (4) A machine washing tends to rather deteriorate girdles than a hand washing does.
    The results of the survey have revealed the parts likely to be deteriorated and reasons of a disuse of girdles
