Zusammenfassung:To provide an optimized fiber combining contact and friction between a filament and a pile yarn and lightness for obtaining excellent pile holding performance.SOLUTION: A hollow polymer fiber has quadrilateral cross sections, in which four peaks substantially form a square shape, all the four sides have a recessed shape or a linear shape, the hollow degree of the cross sections in the fiber falls within the range of 12 to 25%, and the fineness of the fiber falls within the range of 4 to 16 dtex. Specifically, this invention provides a polymer fiber comprising at least one square hollow region, a filter and a carpet comprising the polymer fiber, a non-woven fabric comprising the polymer fiber, the use of the polymer fiber and a pore spinneret discharge port comprising the arrangement pattern of holes designed so as to provide the polymer fiber.SELECTED DRAWING: Figure 3 【課題】優れたパイル保持性能を得るために、フィラメントとパイル糸との接触および摩擦の増加と軽量性とを兼ね備えた最適化された繊維を提供する。【解決手段】四辺形状の断面を備えた中空ポリマー繊維であって、−4つの頂点が実質的に方形を形成し、−4辺すべてが凹状または直線であり、−前記繊維の断面の中空度が12〜25%の範囲であり、−前記繊維の繊度が4〜16dtexの範囲内である、中空ポリマー繊維を提供する。すなわち、本発明は、少なくとも1つの方形の中空領域を含むポリマー繊維、該ポリマー繊維を含むフィルターおよびカーペット、該ポリマー繊維を含む不織布、該ポリマー繊維の使用、ならびに該ポリマー繊維が提供されるように設計された穴の配列パターンを含む細孔紡糸口金吐出口を提供する。【選択図】図3
