摘要：
本发明提供一种凉感聚乳酸纤维，所述的凉感聚乳酸纤维，以质量百分比计，包括以下原料组分：凉感母粒5‑30％、聚乳酸切片余量；所述的聚乳酸切片的粘均分子量为6.0×104‑3.0×105。所述的凉感母粒，以质量百分比计，由以下原料组分熔融混炼制得：偶联剂修饰凉感粉体20‑50%、增塑剂0.1‑5%、抗氧化剂0.05‑1%以及聚乳酸切片余量。本发明制备的凉感聚乳酸纤维：单根纤维的线密度为1.65‑1.68dtex。
摘要（英）：

The invention provides polylactic acid fiber capable of cooling. The polylactic acid fiber comprises the following raw materials by mass percentage: 5-30% of master batch capable of cooling and the balance of polylactic acid slices; and the viscosity average molecular weight of the polylactic acid slices is 6.0*10<4>-3.0*10<5>. The cooling master batch is obtained by performing fusion mixing on the following components by mass percentage: 20-50% of coupling agent modified cooling powder, 0.1-5% of a plasticizer, 0.05-1% of an anti-oxidant, and the balance of polylactic acid slices. The polylactic acid fiber capable of cooling is characterized in that linear density of single fiber is 1.65-1.68 dtex.
