Structures of wool fibers 口 Submicrostructure Cotex can be divided into 2 sections Orthocotex containing less cystine, and thus less s-s b onas Paracortex containing more cystine, absorbing less water two sections spiral around each other along the fiber length the two sections respond to heat and moisture differently forming 3-D crimpStructures of wool fibers ❑Submicrostructure – Cotex ➢ can be divided into 2 sections: – Orthocotex containing less cystine, and thus less S-S bonds – Paracortex containing more cystine, absorbing less water. – two sections spiral around each other along the fiber length. – the two sections respond to heat and moisture differently forming 3-D crimp
