Frictional Properties Friction is a vital important factor in the application of fibrous materials to engineering. Frictional property is the surface property of the fibers when two solid surfaces slide against each other. Due to fiber friction, static charge and heat energy is produced. Friction: Friction is the force of two surfaces in contact, or […]
DFE (Directional Field Effect) in wool fiber What is DFE ? We all know that, textile fibers have to undergo various processes before they become a part of the fabric. While undergoing these processes, the fibers are subjected to friction. This frictional force can not only be effective between the fibres & various parts of […]
Tensile Testing Terms and Tensile Testing Terms Definitions Engineering stress: Engineering stress can be equated to the load applied per original cross sectional area. True stress: True stress can be equated to the load applied per instantaneous (actual) cross sectional area. Unit: N/m2 (Pa) Mass/Specific stress: The ratio between applied load and linear density […]
