A method for the removal of India ink dirt from fabrics involving the reduction of the protective colloid of the glia present in the ink was investigated. The experiment was conducted using gelatin instead of glia. The gelatin was decomposed by the enzymes trypsin, papain and uguis (nightingale feces), and the quantity of generated amino acids was measured with a conductivity meter. It was found that the decomposition was rapid, and a significant amount of decomposition occurred, indicating that a large quantity of the enzymes was present. When the mixture of enzymes was added to an India ink solution, the transmittance of trypsin and papain increased. A washing test was then conducted using these enzymes, and the results were subjected to an analysis of variance test. There was no significant difference observed for the results obtained with the different enzymes after washing (p < 0.05). The results show the detergency higher than enzyme Blank according to fabrics is as follows: uguis and trypsin for PET, uguis for cotton, and uguis and trypsin for polyester/cotton (PC). The low detergency fabrics had much protein residual volume. On the other hand, the high detergency fabrics had little protein residual volume. It was revealed that the glue was removed by washing with enzymes.

The purpose of this study was to clarify the effect of local clothing pressure to the lower extremities on the hemoglobin concentration in the calf muscle, the skin blood flow and the skin temperature in the spine position for clothes design using pressure. Five healthy women laid on a bed and had applied cuff pressure to their upper thighs, middle thighs, above the knees, knees, and legs at 10, 15, 20 mmHg respectively for 15 minutes or without cuff in the artificial climate chamber controlled at 29±0.5℃ and 50±5%R.H. The calf hemoglobin concentration (Oxygenated blood volume in tissue: OXY Hb, Deoxygenated blood volume in tissue: deOXY Hb, Total blood volume in tissue: TOTAL Hb, Oxygen Saturation: StO₂), skin blood flow and skin temperature on the leg and the toe as well as pressure sensation and swelling sensation were measured. The results are as follows:

deOXY Hb and TOTAL Hb increased and StO₂ decreased with the local cuff pressure on the extremities that were significantly changed at 20 mmHg. The increase in deOXY Hb was larger when applied to the knees and the upper thighs than applied above the knees. deOXY Hb significantly increased when applied to the knees and the upper thighs at 15 and 20 mmHg. The leg skin blood flow significantly decreased and rise in the leg skin temperature was suppressed with the application of 15 and 20 mmHg cuff pressure. Swelling sensation was stronger with pressure to the knees than to the upper thighs. These results suggested that particular attention should be paid to the pressure at knee and upper thigh for design of pressure clothes.

The relationship between the silhouette of a heavily eased-in cape collar with the amount of easing and the mechanical properties of the fabric was examined with the aim of effective replication of historically important dresses. The shape of the sample was measured with a three-dimensional measuring instrument, and the volume V was analyzed. The results showed that increasing the easing-in caused V to vary according to the type of fabric. A study on the factors that affect V showed that the apparent density of the fabric had a large effect. The correlation of V with the shear and bending properties increased with the measured length. Multiple regression analyses were carried out where the volume V was considered as the criterion variable for effective replication of a dress and the apparent density, shear modulus, measured length, and easing-in ratio were considered as explanatory variables. With the obtained multiple regression formula, the amount of easing-in required to create a silhouette similar to that of a dress can be successfully predicted with better accuracy.
