Introduction Testing method for bagging (JIS L 1096) which outbreaks around an elbow and a knee, is estimated by the change in the length of cloth after shrinking for the definite length of stretching. However, the cloth is practically stretched and shrank for the great numbers of times. Thus, for the first stage of interest, we only discussed the residual strain of thread as a measure of fatigue after the reiterative stretching and shrinking.
Materials DMC embroidery thread #5(cotton 100%,7.1),cotton hand-sewn thread(15),button thread(polyester 100%,10.9),and Shappe spun sewing thread (polyester 100%,#30 14.5,#50 14.8,#60 18.7,#90 21.1),Nylon sewing thread(nylon 100%,#50 27) were used, where the naked numbers in the parenthesis were the times of twisting for 2.54cm,respectively.
Method 1. Stress-strain curve of the thread: Shimadzu AURTOGRAPH was used for 24C and 65%RH. Initial length was 5.8cm, and the rate of stretching was 3.77cm/min.
2. Reiterative stretching of thread: XY plotter (Graphtec MIPLOT WX4671) equipped with a fitting apparatus of thread by the using of softwear written by BASIC. The testing length was 10cm, and the rate of stretching was 319cm/min. The times of iterative deformation were 100,500 and 1000 each for three times of deformation, respectively. The ratios of extension were 5,7.5 and 10%, respectively, according to the stress-strain curve of thread. However, only of Shappe spun and nylon-thread were investigated for the ratio of extension of 10% and the iteration of 500 times.
Results and Discussions As the ratios of extension and the times of iteration increased, the resulting residual strain increased and vice versa. Further, for the Schappe spun thread, as the twisting number was small for the less number of manufacturing, its value of residual strain had great value. For the thread with less twisting number, as the contact with each other of fiber was weak, so that the permanent strain was remarkable after extension.
Furthermore, as mentioned above, the yarn for weaving and knitting was investigated. We have a plan to do for the various sets of humidity and the rate of stretching. (See an attached figure.)

Purpose: Recently, various substances are supported on fabrics in the aid of skin care. In the present research, the behavior of collagen supported on a cotton fabric will be clarified in the investigation of the sorption/desorption of water vapor to/from the collagen-supported fabric.Method: 1. Collagen was supported to a cotton fabric from its aqueous solution. 2. The uptake of water vapor to the collagen-supported fabric was observed for various time of sorption in the 98% R.H. medium. 3. The discharge of water vapor from the well water-absorbed fabric was also observed. 4. A polyester fabric was used as a reference.Results and Discussion 1. The amount of collagen supported on the fabrics was proportional to the concentration of collagen aqueous solution applied to the impregnation of the fabrics, suggesting the absence of any particular interaction of collagen to the fabrics. 2. The uptake of water vapor to the fabrics was saturated within 3days. The similar uptake was observed for the neat cotton fabric. The saturated amount was linearly related to the amount of collagen supported. The increase of water absorbed to the unit amount of the cotton fabric was 25% of that to the polyester fabric, suggesting that the collagen sacrifices the original absorption property of cotton and absorbs water vapor. 3. The increase of water vapor uptake was proportional to the square root of sorption time at the initial stage of the sorption, indicating the mechanism of the sorption is diffusion in the layer of collagen covering the fiber of cotton. The rate of the sorption was similar to that of polyester's. 4. The similar behavior was observed for the desorption.

purposefood additives, such as an emulsifier, an oil, etc. which are not conventionally used for washing, but can be used for food, were inferior to washing and forming to the food stein, and it was thought that they were not suitable for a cleaner.
then, we examined improvement of this ability of washing and forming for vegetable oil.
methodemulsifier glycerin fatty acid ester and sucrose fatty acid ester,
oilglycerin,liquid paraffin and limonene
contaminated glass glass was sunk with oil red-vegetable oil-chroloform solution and dried for an hour.
washing examination the contaminated glass was immersed in 0.25% test solution and stirred for 3minutes with low speed in room temperature, and rinsed with the hard water.
bubble quantity examination 20ml hard water which contains 0.25% test material in Epton cylinder, was shaked 10 times, and was measured its bubble volume.
resultsperformance of washing and forming of poly glycerin fatty acid ester was improved by using between high and low value of hydrophiie lipophile balance(HLB) by calculating griffin method.
moreover, performance of washing became more better by the combination with liquid paraffine or limonene with poly glycerin fatty acid ester, because of dissolution.
it turns out that it is utilizable to washing materials required the use of food ingredients.
