摘要：
There is provided a non-woven fabric of a crimped composite fiber including: a first propylene-based polymer and a second propylene-based polymer, wherein, in the first propylene-based polymer and the second propylene-based polymer, a melting point of the first propylene-based polymer is higher than a melting point of the second propylene-based polymer by 30ºC or more, a ratio (second polymer/first polymer) of melt flow rates (MFR: measurement temperature 230ºC, load 2.16 kg) of the first propylene-based polymer and the second propylene-based polymer is 1.7 or more, and a component ratio represented by a weight ratio of the first propylene-based polymer/the second propylene-based polymer is 50/50 to 10/90.提供一種一捲曲複合纖維之不織布，其包含：一第一丙烯系聚合物及一第二丙烯系聚合物，其中在該第一丙烯系聚合物及該第二丙烯系聚合物中，該第一丙烯系聚合物之一熔點比該第二丙烯系聚合物之一熔點高30℃或更多，該第一丙烯系聚合物及該第二丙烯系聚合物之熔融流率(MFR：量測溫度230℃，負載2.16 kg)之一比(第二聚合物/第一聚合物)係1.7或更大，且由該第一丙烯系聚合物/該第二丙烯系聚合物之一重量比表示之一組分比係50/50至10/90。
