Fiber fibrillation
WebApr 29, 2012 · Basically fibrillation can be controlled by changing the various spinning parameters such as spinneret size, temperature, draw ratio, air gap conditions and after treatment of the fiber. Commercially, it was found any one of the following methods used for control the degree of fibrillability. WebOne action of refining is the “pumping” of water into the cell wall, making it much more flexible. A second action of refining is fibrillation, that is, exposure of cellulose fibrils to increase the surface area of fibers, thereby improving fiber–fiber bonding in the final sheet.

Web3 The study confirmed the cross-linking of TAHT with the hydroxyl group on the lyocell-type fiber and altogether ceased the fibrillation under high shear force. Cross-linking with TAHT has several ... Fibrillation also occurs with individual skeletal muscle fibers. This happens when muscle fibers lose contact with their innervating axon producing a spontaneous action potential, "fibrillation potential" that results in the muscle fiber's contraction. These contractions are not visible under the skin and are detectable through needle electromyography (EMG) and ultrasound. Fibrillations can occur in healthy individuals. If the fibrillations have irregular potentials then they don't have p…
WebTo evaluate the fibrillation phenomenon clearly, Martindale abrasion machine was applied to promote the fiber fibrillation with 1000 rubbing times. As shown in Fig. 2 a, when NNR was used in a low concentration of 5 g/L, Lyocell fibers were broken down into lots of small fibers after rubbing, exhibiting an obvious fibrillation phenomenon.
