In other words, when the fiber bundle is in the form of cotton, a preferred method for opening the fibers is to put the cotton treated with mercer and other agents into an aqueous solution, swell it, and then apply a physical kneading effect to place it between the single yarns. Causes a phase difference. The aqueous solution used at this time is water 100%
%, or an aqueous solution containing other components as long as the processing effect of the mercerizing agent is not impaired. The temperature of the aqueous solution may be in the range of freezing point to cyto point. As a method of giving a physical kneading effect, there is a method of moving cotton continuously or discontinuously in an aqueous solution, or
There is a method in which an aqueous solution is caused to flow continuously or discontinuously, and the force generated by the flow impacts cotton. At this time, the moving speed of the cotton, the liquid flow speed, the moving speed, the liquid flow speed, the moving direction of the cotton, and the contact angle of the fluid can be determined by a method that imparts a massaging effect without impairing the processing effect of the mercerizing agent. , any method may be used. The time for kneading varies depending on the kneading method, the temperature of the aqueous solution, the components of the aqueous solution, and the length of the fibers, so a specific range is not prescribed, but it can be set as appropriate in consideration of these factors. It is preferable to dry the cotton in a relaxed state after being rubbed with water as described above, since this further improves the fiberability. After the above-mentioned kneading, the cotton is placed on a flexible sheet and passed between metal rollers and rubber rollers to apply pressure and draft, or the upper and lower rollers are rotated in reverse to knead it further. and,! : is preferable because it can further improve the opening property. The $S opened in this way can be easily produced into a spun yarn using a commonly used spinning method.
