Polylactic acid fiber composite flocculus as well as preparation method and application thereof

The invention discloses a polylactic acid fiber composite flocculus, which is prepared from the following raw materials in percentage by weight: 50 to 85 percent of polylactic acid fiber, 12 to 40 percent of bio-based polytrimethylene terephthalate fiber and 3 to 10 percent of cotton fiber. The invention further discloses a preparation method and application of the polylactic acid fiber composite flocculus. Compared with a traditional textile fabric adopting a chemical additive to be matched with modified PET, the polylactic acid fiber composite flocculus does not need to be treated by the chemical additive, so that harmful gas and chemical residues are not generated in production and use; and in addition, in the manufacturing and production processes, the emission of CO2 is reduced by times compared with PET, so that the emission of greenhouse gases is reduced. 本发明公开了一种聚乳酸纤维复合絮片，以聚乳酸纤维、生物基聚对苯二甲酸丙二醇酯纤维和棉花纤维为原料制成，按重量百分比计，三种纤维的配比为：聚乳酸纤维50-85％，生物基聚对苯二甲酸丙二醇酯纤维12-40％，棉花纤维3-10％。本发明还公开了所述聚乳酸纤维复合絮片的制备方法及其应用。相比传统采用化学助
