The invention discloses a sand-carrying fiber and preparation and application thereof. The sand-carrying fiber is a polylactic acid fiber and is prepared from the following raw materials in parts by mass: 100 parts of polylactic acid (PLA), 12 to 16 parts of poly-p-phenylene terephthamide, 3 to 5 parts of sodium dodecyl benzene sulfonate, 2 to 5 parts of citric acid, 15 to 23 parts of polyvinyl alcohol, 10 to 22 parts of glycerin monostearate, 15 to 25 parts of polyethylene glycol, 10 parts of magnesium phosphate-fibrin glue and 2 to 3 parts of zinc chloride. The sand-carrying fiber has the characteristics of simple process route, good sand-carrying performance, strong flow conductivity, excellent dispersity and the like, and the loss of fracturing fluid can be effectively reduced. Magnesium phosphate-fibrin glue and zinc chloride are added into the fiber polymer, so that the prepared sand-carrying fiber has better toughness and solubility. 本发明公开了一种携砂纤维及其制备与应用。该携砂纤维为聚乳酸纤维，其中包括以下质量份数的原料：聚乳酸(PLA)100份、聚对苯二甲酰对苯二胺
