Drape coefficient of the fabric:
It is a very important characteristic of the fabric. It prescribes the fabric deformation by gravity when it is allowed to hang under its own weight. "The drape coefficient is the ratio of the difference between the area of the draped sample and supporting disk to the difference between the area of the specimen and the supporting disk". Its value becomes always less than one. The low value of the drape coefficient shows good draping properties of the fabric. Some factors affecting the drape coefficient of the fabric are given below:
The weight per square unit of fabric:
The weight per square unit of the fabric has a direct impact on the drape coefficient of the fabric. The fabric has a lower weight per square unit always poses better draping properties.

Count and construction of fabric:
If the count of the yarn is the same for two fabrics, the fabric having higher threads count per square inch shows poor draping properties.
If the count of the yarn is the same for two fabrics, the fabric having higher threads count per square inch shows poor draping properties.
If the threads count per square inch is the same for two fabrics, the fabric having coarser yarn count gives poor draping properties.
Type of material:
The type of material to be used in the fabric has a direct impact on the fabric. The cotton fibre gives better draping properties than flax fibre. The soft material always shows better draping properties.

Weave of the fabric:
The loose weave or the weave having low interlacing points give improved draping properties. The plain weave shows poor draping properties than satin or twill weave because of the short float length.
