(EN) ANTIBACTERIAL FIBER, AND METHOD FOR MANUFACTURING ANTIBACTERIAL FIBER
(FR) FIBRE ANTIBACTÉRIENNE, ET PROCÉDÉ DE FABRICATION DE FIBRE ANTIBACTÉRIENNE

Abstract
(EN)
Provided is an antibacterial fiber in which the content of antibacterial glass in the core part is made to be less than the content of antibacterial glass in the sheath part, thereby making it possible for the added amount of antibacterial glass to be small, and further, for the fiber to exhibit superior antibacterial properties. Also provided is an efficient method for manufacturing such an antibacterial fiber. The antibacterial fiber includes a thermoplastic resin and antibacterial glass as added components, the average diameter of the antibacterial fiber is set to be a value within a range of 1-50 μm, and the antibacterial fiber comprises a core part and a sheath part. When the content of the antibacterial glass in the core part with respect to the total amount of the antibacterial fiber is defined as Q1 (weight %), and the content of the antibacterial glass in the sheath part with respect to the total amount of the antibacterial fiber is defined as Q2 (weight %), Q1 and Q2 satisfy relational expression (1): Q1(FR)
L'invention concerne une fibre antibactérienne dans laquelle la teneur en verre antibactérien dans la partie centrale est amenée à être inférieure à la teneur en verre antibactérien dans la partie gaine, ce qui permet à la quantité ajoutée de verre antibactérien d'être faible et, en outre, à la fibre de présenter des propriétés antibactériennes supérieures. L'invention concerne également un procédé efficace de fabrication d'une telle fibre antibactérienne. La fibre antibactérienne comprend une résine thermoplastique et du verre antibactérien comme composants ajoutés, le diamètre moyen de la fibre antibactérienne est défini pour être une valeur comprise entre 1 et 50 µm, et la fibre antibactérienne comprend une partie centrale et une partie gaine. Lorsque la teneur en verre antibactérien dans la partie centrale par rapport à la quantité totale de la fibre antibactérienne est définie comme Q1 (en % en poids), et la teneur en verre antibactérien dans la partie gaine par rapport à la quantité totale de la fibre antibactérienne est définie comme Q2 (en % en poids), Q1 et Q2 satisfont l'expression relationnelle (1) : Q1 < Q2.

コア部における抗菌性ガラスの含有量を、シース部における抗菌性ガラスの含有量より少なくすることにより、抗菌性ガラスの配合量が少量で済み、ひいては優れた抗菌性を発揮することができる抗菌性繊維、及びそのような抗菌性繊維の効率的な製造方法を提供する。 配合成分として、熱可塑性樹脂と、抗菌性ガラスと、を含む抗菌性繊維であって、抗菌性繊維の平均直径を1~50μmの範囲内の値とし、抗菌性繊維が、コア部とシース部とを備えており、コア部における抗菌性ガラスの含有量を、抗菌性繊維の全体量に対して、Q1(重量%)とするとともに、シース部における抗菌性ガラスの含有量を、抗菌性繊維の全体量に対して、Q2(重量%)としたときに、Q1及びQ2が下記関係式(1)を満足する。 Q1<Q2 (1)
