摘要： The present invention has an object to provide a method and a device for opening a fiber bundle, capable of performing a fluctuating operation, at a high speed, of pushing a part of a conveyed fiber bundle by a contact member into a stress state and then separating the contact member from the fiber bundle so as to temporarily relax the fiber bundle, and also capable of reducing damage to the fiber bundle. The device for opening a fiber bundle includes a conveying portion 5 for pulling out a fiber bundle Tm from a yarn feeding body 11 and conveying it in a fiber length direction, a fiber-opening processing portion 3 for opening the fiber bundle by moving a fiber in a width direction while bending the fiber by letting a fluid pass through the conveyed fiber bundle Tm, and a fluctuation imparting portion 4 for rotating a contact member 42 in a direction inclined with respect to a conveyance direction while bringing it into contact with the conveyed fiber bundle Tm and pushing a part of the fiber bundle Tm into a stress state, and then separating the contact member 42 from the fiber bundle Tm in the stress state so as to temporarily bring the fiber bundle Tm into a relaxed state.

摘要： The present invention provides a filament web type precursor fabric for an activated carbon fiber fabric by processes of: (i) spreading precursor filaments for preparing activated carbon fiber in a web state; and (ii) punching the precursor filaments for preparing activated carbon fiber spread in a web state to entangle the precursor filaments for preparing activated carbon fiber with each other. The prepared filament web type precursor fabric for an activated carbon fiber fabric has a structure in which the precursor filaments for preparing activated carbon fiber are spread in a web form and entangled with each other, and has a weight per unit area ranging from 50 to 500 g/m 2 . The present invention may achieve advantages of reducing manufacturing costs, easily controlling a weight of the precursor fabric, and increasing a permeability of the precursor fabric to thus improve a performance thereof, in the preparation of a web type precursor fabric for an activated carbon fiber fabric. When an activated carbon fiber fabric is manufactured by activating the filament web type precursor fabric for an activated carbon fiber fabric of the present invention, durability and crystallinity of yarns forming the above fabric may become higher and uniform, while improving a performance of forming microfine pores having a diameter of 1 to 2 nm, which are easy for hydrogen storage and removal of air pollutants.

摘要： Staple fibre is produced by extruding a solution of a polymer through a spinneret to form continuous filaments, gathering the continuous filaments to form a tow and continuously cutting the filaments in a cutter to form staple fibre. At least one jet of gas is blown at the tow before it enters the cutter to reduce smearing of polymer on the cutter. The process is particularly advantageous for treating water-soluble or water-absorbent filaments.

Thus, the present invention can provide a method for manufacturing and a manufacturing device for a partial split-fiber fiber bundle that can continuously and stably slit a fiber bundle. Specifically, the present invention can provide a method for manufacturing and a manufacturing device for a partial split-fiber fiber bundle that make continuous slit processing possible without having to worry about the exchange life of rotary blades even if the fiber bundle includes twists or the fiber bundle is a large tow having a large number of single fibers, as well as a partial split-fiber fiber bundle obtained using these method for manufacturing and manufacturing device.

摘要： The invention relates to a device (1) for the twist-free width change of a fiber strip (2) of continuous fibers (3) passing through the device (1) to a specified effective width (8). The device (1) comprises a transport unit (4) for transporting the fiber strip (2). The device (1) further comprises at least one width change assembly (5) configured such that the width change assembly (5) transfers an initial distance (a) of two adjacent fibers (3) of the fiber strip (2) to a target distance (b) of adjacent fibers (3) of the fiber strip (2). For a large part of the pairs of adjacent fibers (3), the ratio between the target distance (b) and the initial distance (a) matches within a tolerance range of 20%. This results in a reliable and economical device.

摘要： A steam-drawing apparatus has supply roll 1 that transfers carbon-fiber-precursor acrylic fiber bundle (T) in a transfer direction of fiber bundle (T); fiber-opening device 2 for opening fiber bundle (T); width control device 3 for controlling the width of fiber bundle (T); steam box 4 to provide steam for heating fiber bundle (T) to a temperature that allows fiber bundle (T) to be drawn; and haul-off roll 5 that transfers fiber bundle (T) at a speed faster than that of supply roll 1. Using width control device 3 provided at a position between supply roll 1 and steam box 4, the width of fiber bundle (T) after passing through width control device 3 is set to be 65ˆ¼110% of the width of fiber bundle (T) before entering the supply roll. The present invention proposes a method for producing a carbon-fiber-precursor acrylic fiber bundle using such a steam-drawing apparatus capable of conducting a high-speed drawing process of carbon-fiber-precursor acrylic fiber bundles at a high draw rate with stable results.

摘要： The present invention has an object to provide a fiber-spreading method which can form a thin spread fiber sheet having a large and uniform spread width by uniformly distributing fibers of a fiber bundle having an increased number of fibers, Since a set of regions S i each including a pair of a fiber-spreading region A i and an expansion region B i are arranged in a movable region M set so that the fibers of the fiber bundle can move in the width direction, the fiber-spreading region A i moving the fibers in the width direction while bending the fibers by letting a fluid pass through the fiber bundle, thereby spreading the fiber bundle to a spread width W i (i = 1, ..., n), and the expansion region B i which is set on the upstream side in the feeding direction corresponding to the fiber-spreading region A i and in which the width of the fiber bundle expands toward the end with movement of the fibers in the width direction in the fiber-spreading region A i , by performing pre-spreading in which a movement phenomenon in the width direction caused by distribution of the fibers of the fiber bundle occurring in the fiber-spreading region A i is made to act on the expansion region B i on the upstream side, the fibers can be uniformly distributed in the fiber-spreading region A i and the spread width can be expanded to a predetermined width so as to make the thickness uniform.
