摘　　要：系统测试了含有不同种类、不同重量远红外粉的聚丙烯纤维的100℃远红外发射率，发现纤维中的远红外粉添加量存在最佳值，该最佳值的位置与远红外粉的种类有关，一般在6Wt．％～10Wt．％重量百分含量。在最佳远红外粉含量时，纤维的5～25μm全波长发射率存在峰值。该峰值的存在为得到低成本、高远红外发射率的远红外纤维提供了实验依据。同时测试了采用最佳值时的组成纺制出的远红外丙纶针织布不同温度下的远红外发射率，并与国内外同类产品进行了对比，结果表明，该针织布的远红外发射率明显大于国内外同类产品。We studied the Whole wavelength emissivity of polypropylene fiber containing various types and contents of far-infrared(FIR) radiating powders at 100％. Based on the analysis of experimental data, a optimum content of FIR radiahng powder in polypropylene was given. The optimum content, which is about 6Wt.%-10Wt.%, depends on the type and content of the powder. After a comparison between this fiber and other foreign and domestic products, we came to the condusion that this FIR polypropylene fiber has the highest emissivity.
