があった。Conventional technology> Polyphenylene sulfide is highly crystalline and has i! Since it is a thermoplastic polymer with excellent heat resistance, it is expected to be a fiber with excellent heat resistance and chemical resistance. However, it is extremely susceptible to static electricity compared to polyester, nylon, etc., so in the spinning process, it is difficult to obtain a uniform web due to winding around a part of the cylinder during the carding process or generation of static electricity. In the punching process, there were problems such as the occurrence of roller wrapping of the web.

You won't be able to get a good web. Therefore, even if the needle breakage in the 21-dollar process is reduced, the resulting felt will be highly uneven and uneven.

If the content is less than 50% by weight, it is not preferable because the power training performance becomes insufficient and cylinder wrapping, roller wrapping, etc. occur frequently during the carding process.

It should be a 60-80/20 mixture. If the proportion of component A is less than 30% by weight (relative to all alkyl phosphate alkali metal salts), the antistatic ability will be insufficient and it will be difficult to obtain a uniform web.On the other hand, if the proportion is 90% by weight

On the contrary, it is not preferable because the antistatic ability becomes insufficient. On the other hand, if an alkyl group with a carbon number exceeding 22 is used in combination, the antistatic ability will be insufficient, and if the proportion of component A used is increased to improve this, conversely, cylinder wrapping may occur frequently. This is not desirable.

Further, the acid value is preferably 10 to 40; if it is less than 10, the wrapability will increase, and if it exceeds 40, the solution stability and antistatic ability will tend to decrease. Here, the degree of phosphorylation refers to P for the corresponding alcohol.
For example, an alkyl phosphate with a phosphorylation degree of 1.0 means on average a monoalkyl ester of phosphoric acid, and an alkyl phosphate with a phosphorylation degree of 0.5 means on average a monoalkyl ester of phosphoric acid.

たのである。The polyphenylene sulfide staple fiber of the present invention to which such a treatment agent has been applied must further have crimps of 11 crimps/25 mm or more and a crimp rate of 12% or more. Even if the processing agent gives the polyphenylene sulfide short fibers excellent spinnability to some extent, it alone cannot improve the spinnability to a practically acceptable level. It has long been known that crimp has a large effect on spinnability, but in the case of polyphenylene sulfide short fibers, the effect of crimp on spinnability is particularly large, and the effect of crimp on spinnability is particularly high. It has been discovered that there is a correlation between the number of shrinkages and the degree of crimp, and that there is also a correlation between the number of crimp and the processing agent, and when treated with the processing agent of the present invention,
It was also found that only polyphenylene sulfide staple fibers whose crimp falls within the range of the present invention provide good spinnability.

でのコイラーチューブ詰りが多発する。That is, in the polyphenylene sulfide short fibers treated with the treatment agent of the present invention, the number of crimps is 11/25 mm.
If it is less than that, the entanglement of the wraps, which is an important element in the carding process, will deteriorate, resulting in frequent occurrences of lap licking, wrap-around, cylinder wrapping, etc. in the carding process, as well as roller-wrapping in the drawing process. In addition, coiler tube clogging occurs frequently in the guard and drawing processes, making stable operation difficult. On the other hand, if the crimp rate is less than 12%, the entanglement of the wraps, which is an important factor in the carding process, will decrease, resulting in frequent occurrence of lap licking, wrap-around and cylinder wrapping during the carding process, and Roller wrapping in the process increases, and coiler tube clogging occurs frequently in the carding and drawing processes.

Therefore, it is extremely important to obtain a uniform web in order to reduce needle breakage, and for this purpose, the crimps must be within the above range, that is, the number of crimps is 11 crimps/25 mm or more, and the crimp ratio is 12% or more. There is.

本発明のポリフェニレンスルフィド短繊維が何故上記の
如く優れた紡績性と二一ドルパンチング性を有するのか
その理由は定かでないが、次のように推定される。Effects> The reason why the polyphenylene sulfide short fibers of the present invention have excellent spinnability and 21 dollar punching properties as described above is not clear, but it is presumed as follows.

と推定される。Since a mixture of short and long alkyl phosphate alkali metal salts with alkyl groups within a specific range is used as a processing agent, each has its own shortcomings, and if used alone, it tends to wind up in cylinders, etc. It is presumed that the anti-static effect is insufficient if the long one is used alone).

。In addition, since the fibers are crimped in a specific range,
It is thought that the entanglement between the fibers is improved, and in combination with the effect of the above-mentioned treatment agent combination, the processability in the carding process, drawing process, etc. is improved. Furthermore, since the quality unevenness (particularly thickness unevenness) of the resulting web is reduced, it is thought that needle breakage during the 21-dollar punching process is greatly reduced.

After melting polyphenylene sulfide having a melt viscosity of 1100 voids in an extruder type extruder, the melt viscosity at 0/see is 0. The mixture was discharged from a nozzle having 200 pores with a diameter of 30 mm, cooled and solidified in air, and wound to obtain an undrawn yarn. This spun undrawn yarn is bundled into a tow shape and supplied to a drawing machine, and after drawing in 90°C warm water, 2 coats of the treatment agent shown in Table 1 are applied.
