The purpose of this research was to study Thailand British and German cutting patterns and sewing pants for women with particular figures. The processes were composed of the developmental drafting paper pattern sewing pants and determining the satisfaction surveys. The studies were focused on women having particular pear and round shaped figures as well as the minimum amount of time to develop the cutting pants pattern design. The statistics used were mean and the tested method was performed in randomized complete 3 cutting and sewing ways for 3 types of fabrics including 95/5 polyester & wool blend 100% cotton and 100% linen. These fabrics were applied for developing 9 pants particularly for 5 pear and 5 sphere shaped women and then surveyed for their satisfactions. The results revealed that the designed pants patterns of British style was be able to be made at a short time with the average value of 44.16 minutes. Moreover 5 pear shaped women satisfied the 2nd developing type with the averaged value of 4.82 minutes whereas the other 5 sphere shaped women preferred the 1st developing type having the averaged value of 4.77 minutes. Besides both these two woman groups mostly satisfied 100% cotton pants type with the averaged value of 4.6 and 4.44.

The Purpose of this research was to study the size ratio and structural shape of plus size women determind the standard of dress form and made dress form for plus size women. The representative samples were women’s wears pattern makers students in textiles and clothing field and another related fields which amount 50 persons. The tools of research composed of the questionnaire that evaluated the satisfaction in dress form for plus size women. The statistical analysis were average percentage and standard deviation. The results show that since 1981-2008 the size ratio and structural shape of plus size women in straight shape apple shape pear shape and Hourglass shape had more size ratio in every year. The medium size of plus size women is the beginning shape that is 38. The weight of the woven fabric was 201.90g/sqm; the thickness 0.61mm; the warp size 20.97tex; the weft size 18.44tex; the warp number 44/inch; and the weft number 33/inch. The weight of the knitted fabric was 186.60/sqm; the thickness 0.79mm; the thread size 8.57; the number of vertical loops 35 loops/inch; the number of horizontal loops 30 loops/inch; and the busting strength 179.53lb/inch. It was also found that the satisfaction on dress form for plus size women from woven and knitted fabrics was at the good level with the averages of 4.31 and 4.28.

This research was concerned with dye extraction from the bark of eucalyptus and application for silk and cotton fabric dyeing. Silk and cotton fabrics were treated with premordanting process before dyeing experiments in order to facilitate dye absorbency of fabrics such as silk dyeing at 90ฐC for 40 minutes and pH 4 cotton dyeing at 60ฐC for 40 minutes and pH no adjustment. The best result was achieved when liquor ratio between fabric and dyed solution as 1:30 was employed. Silk dyed in the solution extracting from the bark of eucalyptus with mordant compound displayed yellow to brown colour except fabric using fesrrous (Fe) mordant exhibiting the shade of dark brown to grey. For cotton fabric the shade of yellow to orange was obtained except fabric using ferrous (Fe) mordant displaying the shade of pale grey to gray. Silk and cotton fabrics treated with pre-mordanted and dyeing process has presented the properties of colour fastness to washing water and perspiration from good to very good level whereas colour fastness to light and rubbing was from fair to good level.
