A measurement system () for detecting repeated large deformation comprising: a fiber optical strain sensor () including a flexible polymer optical fiber (POF) () in the form of a series of extended loops (), the loops () being flexible to allow rotation in the plane; and notches () formed on at least one side of the fiber (); a light source () connected to the POF (); and a photo-detector () to detect a change of the light power transmission loss through the notches () caused by the alteration of the shape of the notches () when the strain sensor () is strained.

The present invention relates to a machine, a system, and textiles resulting from an industrially produced yarn, created through the incorporation of a linear false twisting device and two lappets positioned to affect a yarn during drafting. The invention results in a yarn having a low twist multiplier. The textiles products created from the produced yarn exhibit a soft feel without requiring the use of chemical treatments.
