广东费飘职业故本学院 Guangdong Inatitute of Textile Technology Structures of wool fibers 口 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 er len the two sections respond to heat and moisture differently forming 3-D crimp
Structures 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
