Feather fibres

Fig. 3. Substructure of a spindle-shaped (a) and a feathered (b) skeletal muscle. The orientation of the myofibres and of the fatty septa arranged along the fibre bundles are indicated schematically.

Fig. 16. Single voxel STEAM spectra of the SOL muscle (top) and the TA muscle (bottom). Different fibre orientation in those muscles results in clearly different patterns of the lines in the spectra In SOL (feathered muscle with oblique fibres), IMCL and EMCL signals show lower frequency separation than in TA (spindle-shaped muscle) due to bulk susceptibility effects. Furthermore, in SOL the Cr2 doublet merges into one resonance, the Cr3 triplet is less resolved, and TAU is shifted towards TMA.

The raw materials used for the preperation of regenerated protein fibres may be milk, soyabeans, peanuts and zein. Sometimes alkaline solutions of gelatin, albumin and other raw materials like waste wool, silk and feathers may be used. Fibrolane (Great Bretain) and Merineva (Italy) are made by dissolving casein in sodium hydroxide, and then by extrusion into an acid/saltbath. The fibres formed in this way... 

Animal fibres and filaments, proteinaceous substances taken from hair or fur (e.g., wool), down or feathers, and cocoon materials. 

Composite materials made with natural fibres such as hemp, flax, ramie, banana, jute or chicken feathers as the reinforcing agents, and...
