Abstract

A pile yarn, preparation method and application thereof are provided. The method includes: in the process of uniform motion of multifilaments, using the high-pressure airflow to feed short fibers into the fiber transfer channel of multifilaments to prepare the pile yarn; the number of monofilaments in the multifilament is 30-50; the pressure of the high-pressure airflow is 1-2 MPa; the included angle of 85-90° is formed between the feeding direction of the short fibers and the transferring direction of the multifilaments; the average length of short fibers exposed from the outermost monofilament surface of the multifilament in the prepared pile yarn is 3-5 mm. The application includes: using the pile yarn as all or part of the raw material, processing according to the general processing technology to prepare the pile fabric; the general processing technology is a technology which does not contain an electrostatic flocking or pile cutting procedure.
