Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、主として洗車用等の回転ブラシに関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention mainly relates to a rotary brush for car washing and the like.
洗車用等の従来の回転ブラシにおけるフィラメントに
は、低密度ポリエチレンを主成分とする原料を押出し加
工したものが使用されている。As a filament in a conventional rotary brush for car washing or the like, an extruded raw material containing low-density polyethylene as a main component is used.
上記のような低密度ポレエチレンを主成分とする長寸
のフィラメントの一部を回転基体に止着してなる回転ブ
ラシを使用すると、ブラシのフィラメントの先端が被洗
浄面を勢いよく叩打し、かつ摺擦する際に、フィラメン
トを構成している低密度ポリエチレンの構造の一部が破
壊して離脱し、フィラメントは急速に摩滅して、短期間
の中に使用に堪えなくなる。When a rotating brush formed by fixing a part of a long filament containing low density polyethylene as a main component to a rotating base as described above is used, the tip of the filament of the brush slams the surface to be cleaned, and During rubbing, a part of the structure of the low-density polyethylene that constitutes the filament is broken and detached, and the filament is rapidly worn away and becomes unusable in a short period of time.
本発明は、洗浄に際し、微細繊維状組織の破断並びに
離脱を、皆無もしくは可及的に小としたブラシ用モノフ
ィラメントを備える回転ブラシを提供することを目的と
するものである。An object of the present invention is to provide a rotary brush including a brush monofilament in which breakage and detachment of a fine fibrous structure at the time of cleaning are eliminated or minimized.
本発明の回転ブラシは、高結晶性ポリオレフィンから
なる糸条体を、初期の長さの５〜23倍に延伸することに
より、高分子鎖を、繊維軸方向に配向させてあり、かつ
繊度を約1000〜9000デニール、弾性率を0.1〜10ギガパ
スカルとしたモノフィラメントの両端部を適宜長に亘っ
てフィブリル化したものの束を２つ折りし、かつその折
り部を、円筒体に設けた保持孔へ挿入して固着してなる
ものである。The rotating brush of the present invention has a polymer chain oriented in the fiber axis direction by stretching a thread made of a highly crystalline polyolefin to a length of 5 to 23 times the initial length, and has a fineness. Approximately 1000 to 9000 deniers and elastic modulus of 0.1 to 10 gigapascal. Monofilaments with both ends fibrillated for appropriate lengths are folded into two bundles, and the folds are inserted into holding holes provided in the cylinder. It is inserted and fixed.
本発明の回転ブラシのモノフィラメントにおいては、
高分子鎖が繊維軸方向に配向しているため、叩打もしく
は摺擦しても、高分子の微小片が離脱して摩滅すること
はなく、初期の使用に堪えうる。In the monofilament of the rotating brush of the present invention,
Since the polymer chains are oriented in the fiber axis direction, even if it is struck or rubbed, the polymer micro-particles do not separate and wear away, and they can be used for the initial use.
本発明において使用されるモノフィラメントの製造に
際しては、メルトインデックスが1.5以下、密度が0.95
以上、望ましくは0.96以上である高分子量ポリエチレ
ン、あるいは、メルトインデックスが1.5以下であるア
イソタクチックポリプロピレンのような高結晶性ポリオ
レフィンのペレットを出発原料とする。In producing the monofilament used in the present invention, the melt index is 1.5 or less, the density is 0.95.
As described above, pellets of high crystalline polyethylene having a melt index of 1.5 or less, or high crystalline polyethylene having a melt index of 1.5 or less, as a starting material, are preferably used.
このような原料を、公知の一般的な手段により高延伸
処理して、高強度、高弾性率の繊維状構造体とする。Such a raw material is subjected to high-stretching treatment by a well-known general method to obtain a fibrous structure having high strength and high elastic modulus.
しかし、単に延伸して、高分子鎖を繊維軸方向に良好
に配向させただけでは、繊維軸と直角方向に作用する分
子間の結合力は小となり、繊維構造における切断面に近
いところから長手方向に避けて、フイブリル化を発生し
易くなる。However, simply stretching and orienting the polymer chains well in the fiber axis direction reduces the binding force between the molecules that act in the direction perpendicular to the fiber axis, and lengthens from a point near the cut surface in the fiber structure. The fibrillation is likely to occur by avoiding in the direction.
このフイブリル化する性質は、不織布、ロープ、コー
ド、魚網などを製造するのに好ましいものであるが、こ
のようなモノフィラメントをもって回転ブラシを形成す
ると、裂断された各糸条体が容易に切断して、長期の使
用に耐えなくなる。This fibrillating property is preferable for producing non-woven fabrics, ropes, cords, fish nets, etc., but when a rotating brush is formed with such monofilaments, the torn filaments are easily cut. It becomes unbearable for long-term use.
そのため、本発明において使用されるモノフィラメン
トは、フィブリル化が容易であるとともに、裂断された
各糸条体が十分な強度と耐久性を有するようになってお
り、その製造は、例えば次のようにして行われる。Therefore, the monofilament used in the present invention is easy to fibrillate, and each of the torn filaments has sufficient strength and durability. Is done.
