アパレル縫製におけるスーツの表布と接着芯についての考察

　During lessons how to sew a suit by the computer-aided-designed apparel in our college, use of the glue-backed pads is considered to be quite important for making a excellent suit and forming a good silhouette.　Under various conditions, adhesion of face fabrics of the suit cloths with the glue-backed pads was carried out. The degree of shrinkage of the fabrics and pads was measured by changing the temperature, pressure and time during the press process for the adhesion. It was considered that the optimum conditions for the adhesion were 150℃, 300g／㎠, and 10sec under the experimental conditions. Under the optimum conditions, three kinds of suits were prepared in the teaching of apparel sewing, and satisfactory results were obtained

布の保温性測定装置の製作とその測定

　布の「保温性」は被服の大切な性能の一つである。その「保温性」測定方法について，従来の測定法を基にし，測定装置の改良を行った。改良した測定装置は，従来の「カタ温度計法」と「牛乳瓶法」での測定装置の問題点を解消し，また「保温性」と実際の被服条件との関係をより明確に評価することが可能となった。さらに，最近の技術の向上による「保温性」と「軽さ」を強調した布についても同様に測定した結果，妥当な結果が得られたので，それらの研究を本論文で報告する

さくら染の研究 第4報 浸染液のpHが染着性に及ぼす影響

　A study on traditional dyeing by plant extract from fallen leaves of cherry tree was carried out. The effects of pH of dip bath on dyeabilities were investigated. The extraction liquid was prepared by dissolving sodium carbonate into distilled water at the concentration of (0.05～10) g/ℓ. Dip bath was prepared from the mixture of the extract and buffer, and the dipping liquid was adjusted at pH 3～7. Estimation of dyeability of dyed fabric was carried out by measuring L* ,a* and b* using a spectro-color meter. Dyeing of twilled silk was carried out through mordant dyeing using several mordants. The remarkable effect of pH of dye bath was clarified, and excellent and clear dyeability was obtained in the case of high value of pH 5～6. Superior dyeability was obtained at pH 6 in the case of iron mordanting, and clear deep grey dyeing was given, and dyeability was low at pH 3～4 and 7. Difference of dyeability obtained by two extracts, one by distilled water and the other by tap water was investigated. Dyeability of extract by tap water was clarified more superior than by distilled water

The Effects on dyeability of pH of extraction liquid were investigated. The pH values of extraction liquid were adjusted at 6-12, using buffer solutions. Dip bath was prepared from the mixture of neutrized extract and buffer solution. pH of the dipping liquid was adjusted at 3-7 using the buffer solution. Dyeing clothes of twilled fabric of silk were used for the experiments. Dyeability was estimated using spectro-color meter by measuring L*, a*, and b*. The effect of pH of extrction liquid on dyeability was distinct. At higher pH values of 11 and 12, increased dyeability was obtained and the fabric dyed very dark brown. At lower pH values of 8-10, lower dyeability was found and it dyed clear and light. However the color property was superior. The effects of repeat dyeing were investigated. When times of repeat dyeing were increased, chenges of hue and distinction were observed, and deep colors were obtained. Especially the color difference was very large between the first and the second dyeing
