During the wear of clothes, the clothing fabrics change their mechanical properties by repeated deformation. This is also a fatigue phenomenon which depreciates the value of the cloth. In order to simulate this phenomenon a fatigue testing machine has been developed. The fabric specimen undergoes repeated shear deformation under constant extension load. After this cyclic deformation is applied, the mechanical properties of the specimen are measured by KES-F fabric testing system and the change in “Handle” of the specimen is also examined using those data and the equation for mechanical property-hand value translation.
Remarkable changes are observed in shear and tensile property after about 10⁴ cycles of the repeated deformation. The amount of change differs between two groups of the fabrics ; high- and low- quality groups. The differences are also examined in the fatigue properties of knitted and woven fabrics of worsted, wool/polyester blended and textured yarns.

This study aims to find out mechanical properties of fabrics which contribute to the easiness for handling in making-up and to a good appearance as men's suit in finished garment.
As the mechanical properties of the fabrics, measurements were carried out on the characteristics of extension, bending, shearing and compression and also of the friction and surface contour, The making-up properties of the fabrics were evaluated by eighteen making-up personnels, who classified the fabrics according to the easiness in making-up and their appearance. The results are summarized as follows :
1) Easiness of fabrics for handling in making-up is obtained within the particular range in tensile, bending, shearing and compressional properties. The larger ratio of plasticity to elasticity in bending and shearing properties gives more easiness.
2) Fabrics which offer a good appearance in finished garment have the mechanical properties of almost same range as good “handle” of fabrics, or of fabrics which have a little easiness for handling in making-up. Further, the complex physical properties, which are related to the deformation in the gravitational field, contribute to the good appearance as men's suit in finished garment
3) Fabrics having the easiness for handling in making-up and fabrics offering a good appearance in finished garment are associated with the moderate value of taking-in and settability .
