Wool Fiber - Chemic Composition Of Wool
Saturday, 6 July 2013
Edit
Wool is a beast fiber of outstanding importance. It is a poly peptide fiber collecting from fur of sheep. This poly peptide fiber consists of C, H, O, N, due south etc. Wool is real fine, elastic fiber. Hair of about animals fibers tin live considered every bit textile fiber but wool has exceptional features which distinguish it from other hairs but which renders it supremely valuable every bit a textile fiber. These differences are of a physical nature as well as the basic tissues as well as chemic construction of all beast hairs, including wool, are similar.
The wool fiber is complex inwards construction as well as composed essentially of 3 tissues, the cuticle, the cortex as well as the medulla. Each of these, nevertheless is farther subdivided past times tissue differentiation. A purely diagrammatic representative of the construction of a non-medullate fiber has shown inwards image.
The epi-cuticle as well as exo-cuticles of wool incorporate a high proportion of sulpher amongst many cystine cross linkages giving them a high mensurate of resistance to biological as well as chemic attack. The endo-cuticle of the other mitt is somewhat less resistant. There are inter-cellular membranes which act every bit a concent asset the cuticle to the side past times side tissues. It is seen from the structural icon that the cortical cells are composed of macro-fibrils, each of which incorporate a number of micro-fibrils lying parallel amongst each other.
Chemical Composition of Wool:
Component | Percentage |
Keratin | 33% |
Dirt | 26% |
Suint | 28% |
Fat | 12% |
Mineral Matters | 1% |
Total | 100% |
Wool is poly peptide fiber thence it incorporate keratin every bit a protein. This fiber contains unnecessary substances upwardly to lxx percent inwards its chemic constituents. The poly peptide substances of wool keratin composed of the C, H, O, N, due south amongst the next percentage.
