大発明は密閉型アルカリ電池、特にニッケルカドミウム
蓄電池に用いるアルカリ電池用七ノ（レータ−の構成に
関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a structure of an alkaline cell regulator used in a sealed alkaline battery, particularly a nickel-cadmium storage battery.

ものが見られる。このように繊維を多孔性とじたと七に
より、電解液の保液量は均一となり、それがため放電容
量が大きくなるという特徴がある。Conventionally, nonwoven fabrics made only of polyamide fibers have been generally used for alkaline batteries (7) (lators), which take advantage of the properties of polyamide fibers such as water absorption and liquid absorption. In order to further improve pharyngeal properties, some fibers are eluted with inorganic salts to create a porous structure.By binding the fibers in a porous manner in this way, the amount of electrolyte retained becomes uniform; It has the characteristic of increasing discharge capacity.

では劣化が著しく、長期の使用に耐え難いという欠点が
ある。However, in alkaline batteries, under conditions such as high temperatures and continuous overcharging, the temperature rise of the electrolyte and electrochemical changes are large, so the polyamide nonwoven fabric separator described above deteriorates significantly and cannot be used for long periods of time. It has the disadvantage of being difficult to tolerate.

点がある。In addition, there are separators made of nonwoven fabric made of polyamide fibers mixed with polypropylene fibers that are resistant to electrolyte solutions, but since the fibers are bonded together by heat welding, the polypropylene fibers shrink significantly during heat welding, making it difficult to This method requires detailed process control, and has problems such as the difficulty of manufacturing uniform products in large quantities and at low cost.

りラインアップされていないのが現状である。There are non-woven fabrics made using a polypropylene resin melt-produced method, and non-woven fabrics made using a wet-process polypropylene fiber method as separators, but although they can satisfy battery properties such as liquid absorption and alkali resistance, they have drawbacks in the manufacturing method. Due to the low mechanical strength of the separator, problems such as elongation and cutting of the separator occur during the battery manufacturing process, so it is currently not available in the lineup.

、劣化による形態変化が著しく、大巾な性能低下をきた
すことになる。Furthermore, a separator has also been devised in which a mixed web of polyamide fibers and polybrohylene-polyethylene composite fibers is heated and pressurized to melt the polyethylene component and bond the fibers together. However, the above polypropylene
There is a problem that the mixing ratio of polyethylene composite fibers is very limited. That is, if the composite fiber content is less than 20%, the adhesive strength will be insufficient and it will not be possible to apply it to the battery assembly process, and if 20 to 5096 composite fibers are mixed to give strength, the polyamide fiber will be included in the polyamide fiber of 5096 or more, which will cause deterioration. This is not desirable due to problems, and the above composite fibers are
If more than % is mixed, it tends to form a film when heated and pressurized.
It has a negative effect on the performance as a separator. As described above, since the mixing ratio of polypropylene-polyethylene composite fibers is extremely limited, and the presence of polyamide fibers, the morphology changes significantly due to deterioration, resulting in a large drop in performance.
本発明は上記諸欠点を克服し、如何なる条件下でも十分
実用に供し得るアルカリ電池用セパレーターを提供する
ものである。The present invention overcomes the above-mentioned drawbacks and provides a separator for alkaline batteries that can be put to practical use under any conditions.
以下本発明の１実施例を詳細に説明する。One embodiment of the present invention will be described in detail below.

池用上〕（レータ−を形成する。The separator for alkaline batteries of the present invention is produced by simultaneously spinning two types of polymers (polyamide resin and polypropylene resin) using a specially shaped spinneret, and producing fibers with a radial multilayer lamination structure and polypropylene fibers. Use polyethylene side-by-side fibers or mixed fibers with seabird type composite fibers. For example, 80% polypropylene resin, polyacet mWf! 80% polypropylene resin single edge that constitutes the fiber at a ratio (weight ratio) of 20% (approximately triangular prism shape and arranged radially from the axis, and the triangular prism-shaped polypropylene resin pieces are made of 2096 polyamide resin) 7 radial multilayer laminated composite fibers are obtained by simultaneously spinning them using a specially shaped spinneret so that they have a laminated cross-sectional shape.

A random web or a cross web with a basis weight of 90 f/d is formed by passing the mixed fibers through a land ueno (-) machine or a card machine, and then passing through a pair of heated and pressurized rolls to melt the polyethylene component to form the web constituent fibers. The plates are bonded together to form a plate for alkaline batteries with an apparent density α2 to 0.5 f/-.

。The weight of the separator is changed between 40 and 200F/- depending on the purpose of use, and if the apparent density is less than 0.20F/-, the strength of the separator The liquid absorption rate decreases, and if it exceeds 5 f/-, the pores become too clogged and the passage of oxygen generated by electrolysis is inhibited, which is not preferable, and it is necessary to maintain an appropriate gap, preferably 0.20~ Adjust to 0.50y/-.

てセパレーターを構成する。As shown in FIGS. 1 and 2, the polypropylene-bolyamide radial multilayer composite fiber used in the present invention has a triangular prism-shaped polypropylene resin component (
The polypropylene resin component (!) of the composite fiber 1 has excellent alkali resistance and has a structure in which 1) are arranged radially from the core and adjacent parts are bonded linearly with the polyamide resin component (2).

しての性能低下は極力押えられる特性を持つ。Therefore, although the initial performance of the polyglopylene-polya radial multilayer laminated composite fiber, which is the main constituent fiber of the separator, is inferior to the side-by-side composite fiber using the same resin, it remains the same as the polypropylene fiber even after the polyamide component has deteriorated. The remaining polyamide component causes a capillary phenomenon, which has the characteristic of minimizing performance degradation in separators for alkaline batteries.

合繊維表面の一部乃至全部と占めることが必要である。Further, in the form of polypropylene-polyethylene composite fibers that serve as adhesive fibers between the fibers, it is necessary that the polyethylene component necessarily occupies part or all of the surface of the composite fibers.

ができる。Since the present invention is configured as described above, the role of the M ratio of polypropylene-polyethylene composite fibers serving as adhesive fibers is limited only to adhesive strength, that is, tensile strength retention properties, and the minimum mixing ratio (80 to 50%).
また電堺液によるセパレーターの劣化による形態変化が

The water absorbency of the polyamide resin and the liquid absorption rate due to capillary action are greatly increased, and furthermore, even after the polyamide resin part has deteriorated, it exhibits sufficient liquid absorption performance.
