In addition, the composite fiber 10 is roughly in the shape of a round strip.

於一較佳實施例中，該芯材11為聚丙烯共聚物或聚丙烯均聚物所製成，該外殼12為聚乙烯共聚物、聚乙烯均聚物、聚丙烯共聚物或聚丙烯均聚物所製成；精確來說，用於製備該外殼12的聚乙烯共聚物、聚乙烯均聚物、聚丙烯共聚物及聚丙烯均聚物之熔化溫度低於用於製備該芯材11的聚丙烯共聚物及聚丙烯均聚物；換言之，用於製備該外殼12的聚乙烯共聚物、聚乙烯均聚物、聚丙烯共聚物及聚丙烯均聚物依序為低熔化溫度的聚乙烯共聚物、低熔化溫度的聚乙烯均聚物、低熔化溫度的聚丙烯共聚物及低熔化溫度的聚丙烯均聚物，而用於製備該芯材11的聚丙烯共聚物及聚丙烯均聚物則依序為高熔化溫度的聚丙烯共聚物及高熔化溫度的聚丙烯均聚物。 In a preferred embodiment, the core material 11 is made of polypropylene copolymer or polypropylene homopolymer, and the outer shell 12 is made of polyethylene copolymer, polyethylene homopolymer, polypropylene copolymer or polypropylene homopolymer. To be precise, the melting temperature of the polyethylene copolymer, polyethylene homopolymer, polypropylene copolymer and polypropylene homopolymer used to prepare the shell 12 is lower than the melting temperature used to prepare the core material 11 Polypropylene copolymers and polypropylene homopolymers; in other words, the polyethylene copolymer, polyethylene homopolymer, polypropylene copolymer and polypropylene homopolymer used to prepare the shell 12 are in order of low melting temperature poly Ethylene copolymer, low melting temperature polyethylene homopolymer, low melting temperature polypropylene copolymer and low melting temperature polypropylene homopolymer, and the polypropylene copolymer and polypropylene homopolymer used to prepare the core material 11 The polymer is a polypropylene copolymer with a high melting temperature and a polypropylene homopolymer with a high melting temperature in sequence.
