Description
次に、本発明の摩擦防融複合繊維の断面形状について説明する。
本発明の摩擦防融複合繊維は、上述のような海成分と、島成分とからなる海島型複合繊維である。本発明において、海島型複合繊維は、１以上の島成分と、１以上の海成分を複合してなる繊維である。
図１〜図４は、本発明の摩擦防融複合繊維の長手方向に垂直な切断面の形状の例である。
図１、図３は、海成分の数が１、島成分の数が１の海島型複合繊維の断面である。
図２、図４は、海成分の数が１、島成分の数が１９の海島型複合繊維の断面である。図２、図４の海島型複合繊維の島成分は、中心に１個、中心の島成分の外周を均等に１例に囲んで６個、その外周を均等に１列に囲んで１２個の合計１９個配されている。
なお、本発明における海島型複合繊維の海成分および島成分の数は１以上であれば、特に制限されるものではないが、口金作製の容易さから、６１島以下が好ましく、３７島以下がより好ましく、１９島以下が最も好ましい。
海成分と、島成分の好適な比率（断面積比率）としては、島成分に低融点樹脂のみを用いる場合は、島成分：海成分比率が、５：９５〜５０：５０が好ましく、より好ましくは１０：９０〜３０：７０である。また、島成分に海島型アロイ樹脂を用いる場合は、島成分：海成分比率が、２０：８０〜７０：３０の範囲が好ましく、より好ましくは、３０：７０〜５０：５０である。この範囲であると、紡糸性も良好であり、本発明の効果も奏しやすい。
Next, a description will be given cross-sectional shape of the friction BoToru composite fiber of the present invention.
The friction-proof composite fiber of the present invention is a sea-island type composite fiber comprising the sea component and the island component as described above. In the present invention, the sea-island type composite fiber is a fiber composed of one or more island components and one or more sea components.
1 to 4 are examples of the shape of a cut surface perpendicular to the longitudinal direction of the antifriction composite fiber of the present invention.
1 and 3 are cross-sections of sea-island type composite fibers having one sea component and one island component.
2 and 4 are cross-sections of sea-island type composite fibers having one sea component and 19 island components. The island component of the sea-island type composite fiber in FIGS. 2 and 4 is one in the center, six in the outer periphery of the central island component evenly surrounded by one example, and 12 in the outer periphery evenly surrounded in one row. There are 19 in total.
The number of sea components and island components of the sea-island type composite fiber in the present invention is not particularly limited as long as it is 1 or more, but is preferably 61 islands or less, and 37 islands or less from the viewpoint of easy production of the base. More preferably, 19 islands or less are the most preferable.
As a suitable ratio (cross-sectional area ratio) of the sea component and the island component, when only the low melting point resin is used for the island component, the island component:sea component ratio is preferably 5:95 to 50:50, and more preferably Is 10:90 to 30:70. When a sea-island alloy resin is used as the island component, the island component:sea component ratio is preferably in the range of 20:80 to 70:30, and more preferably 30:70 to 50:50. Within this range, the spinnability is good, and the effects of the present invention are easily exhibited.
