The polytrimethyleneterephthalate fibers have an intrinsic viscosity of 0.7-1.3 dl/g, a LASE (load at specific elongation at 10 %) of 5-12 cN/tex, a secant modulus (Rd-45%) of lesser than 1 cn/tex per 1 %, a crimp resistance of greater than 75% and can be dyed without addition ...
Here you see a linen thread that has been partially unspun, and a drop of red dye then placed on a nearby unspun portion. The dye migrates at high speed in the gaps between fibres, then comes to an abrupt halt when the fibres are too far apart to permit capillary migration. See later...
