TAKING-UP OF PITCH GROUP CARBON FIBER
PURPOSE:To permit the rewinding from a product bobbin free from the thread cut, fluffing, etc. by taking up the pitch group carbon fiber having an elongation modulus of 400ton/mm or more onto a taper end bobbin at an edge angle and a taper end angle of each specific value. CONSTITUTION:When the pitc...

| description | PURPOSE:To permit the rewinding from a product bobbin free from the thread cut, fluffing, etc. by taking up the pitch group carbon fiber having an elongation modulus of 400ton/mm or more onto a taper end bobbin at an edge angle and a taper end angle of each specific value. CONSTITUTION:When the pitch group carbon fiber 3 having an elongation modulus of 40ton/mm or more and an elongation of 1% or less is taken up onto a bobbin 4, taking-up operation onto a tapered end bobbin is carried out with an edge angle 1 of 0.1-25 deg. and a tapered angle 2 of 10-70 deg.. In concrete, taking-up is carried out in one layer with a prescribed edge angle so that the fibers are not superposed from one edge of the bobbin 4 to the other edge, and then turn-over operation is carried out, and the fiber bundle is taken up in one layer. The edge angle is changed by varying the traverse speed. In other words, generation of thread cut, etc. on rewinding is prevented by sufficiently preventing the state where the fiber bundle taken up onto the upper layer side is dropped into the fiber layer on the lower layer side. |
