れて来た。 When producing fibers, some of the fibers produced by dry spinning and wet spinning are washed with water after spinning, but in order to increase the washing effect, the temperature of the washing water is raised within an allowable range. Efforts have been made to countercurrent the flow of water, blow air, or boil the water to promote renewal of the washing water on the fiber surface.

した。 The present inventor has doubts about the necessity of boiling the washing water throughout the cascade in the so-called cascade washing process in which boiling water is continuously passed through the washing process following spinning during fiber production, and as a result of intensive research, the inventor has found that For fiber bundles where the renewal of cleaning water on the surface is rate-determining, and for thick denier fibers where diffusion inside the fibers is rate-determining, there is not much difference in the cleaning effect even when passing through partially boiling hot water. They discovered that there is no such thing and conducted further studies to arrive at the present invention.

This is a continuous fiber cleaning device in which the washing water in the upper part of the heating section is heated to boiling water and then merged with other flows by repeating the division and merging process, while the spun fibers are passed through the boiling water in the upper part of the heating part.

条件である。 In the present invention, the cascade is partially provided with a plurality of boiling water regions to perform intermittent boiling water treatment, in other words, multi-stage boiling water treatment on the fibers. It is best to partially divide the water flow into upper and lower parts at appropriate intervals, and to install heating parts at each of the positions where the water flow should be divided, so that the cleaning water boils only at the top of each heating part. No special heating is applied to the lower part and other parts. Therefore, the wash water supplied to the cascade is supplied at a temperature that allows suitable washing, and since the fibers pass through a region of partially boiling water, the temperature of the wash water throughout the cascade is kept well below the boiling point; The amount of wash water has increased substantially to the extent that evaporation is suppressed. According to the invention, by providing boiling water regions at appropriate intervals,
The cleaning water on the fiber surface is renewed and the solvent diffusion inside the fiber is promoted by heating. Therefore, sufficient renewal of the washing water on the fiber surface and sufficient diffusion within the fiber are necessary conditions for rapid washing.

である。 The drawing is a cross-sectional view showing an example of the apparatus of the present invention, in which washing water 2 is supplied to the cascade 1 from a washing water supply port 3 and is discharged from a discharge port 4 after washing. On the other hand, the fibers 5, which are the objects to be washed, enter the washing water in a countercurrent flow. 6 is the liquid level. The fibers 5 that have entered the washing water pass through the washing water to a heating section 7 provided in the washing water.
The heated washing water passes through the boiling region 8 and promotes surface renewal on the fiber surface.
Subsequently, after passing through a region where the temperature has not reached the boiling state, the water passes through the boiling state region 8' again, and this process is repeated. After the washing water is supplied to the cascade 1 from the supply port 3, it is divided into upper and lower parts at the heating section 7'', and the washing water located above the heating section 7'' is heated by the heating section 7'' to a boiling state, and the fibers are heated. Promotes renewal of cleaning water on the surface area and strengthens cleaning.
The upstream washing water, which has a higher concentration of the washing extracted from within the fibers, then joins and mixes with the downstream washing water, which is cooler and has a lower concentration than the upstream washing water, which has flowed through the lower part of the heating section. Diluted. The washing water repeats such diversion and merging and heads toward the outlet 4, but
The temperature of the cleaning water in the vicinity of the discharge port 4 is relatively low, and the heating energy can be made much lower than in a method in which the cleaning water of the entire cascade 1 is heated to boiling. However, in the present invention, although the heating energy is low, it is possible to effectively keep the temperature of only the cleaning water that exists near the fibers, which is effective for cleaning the fibers, high. Note that it is preferable to provide a jammer plate 9 in the cascade in order to smoothly agitate the washing water by merging it.

They were installed at positions of 0.2m, 1.5m, 3m, 4.5m, and 6m, respectively. 70 at 10/min from the fiber extraction side
℃ hot water was supplied, and a cascade was set to a depth of about 10 mm at the top of the heating section. A jamb board having the same height as the top surface of the heating part was installed between the heating parts. This cascade has 750,000 denier/
A coagulated fiber bundle of 50,000 filaments is supplied and stretched 5 times at 40 m/min when taken out from the cascade.
When the amount of residual solvent in the wet fibers taken out was measured, it was 0.4% based on the dry yarn. This was almost at the same level as the result of a boiling water cascade system of the same length in which the entire cleaning water was brought to a boiling state. On the other hand, when the amount of evaporated water was measured using a cascade cover with a gutter, it was found that 15
