Abstract
A comprehensive study on drape percent and drape coefficient has been made on 100 percent Grieg cotton fabric with plain weave. The method employed to measure the drape of fabric was Cusick's drape-meter with light source. Six samples were taken which had the same weave, equal number of end and picks per inch with the same finished width. The variable taken was the difference in weft and warp yarn counts in which every sample had a different yarn count for the weft while the warp yarn count was same for the six samples. This constructional difference in yarn counts changed their individual drape behaviors. After taking drape measurements for all the six samples they were laundered by using home laundering cycle conditions as described in AATCC 124-2000 methods. Then again the same tests were taken and the measurements after washing were calculated. This experiment gave knowledge about their individual drape behavior as well as a comparison can be seen in results after samples were washed once. A general rise in drape percent has been noticed as the weft yarn counts became finer because the fabric was less stiff thus resulting in more drape-able. Measurements after one washing cycle showed a handsome increase in drape percent for each sample respectively but again the trend was same according to the weft yarn count fineness. This shows that finer counts in fabrics results in more beautifully draped fabric than the coarser ones. And also when the Grieg fabric is washed it enhances the drape-ability of it. This drape behavior is required in draperies, bed-linens, table linens and other upholstery applications.
