Abstract

The invention relates to a preparation method of a polyester porous yarn. A polyester fusant is subjected to metering, porous spinning plate extrusion, cooling, oiling, stretching, heat setting and winding to prepare the polyester porous yarn, wherein the pore number of a porous spinning plate is 144 to 288; an oil agent for oiling contains crown ether; the content of crown ether is 67.30 to 85.58weight percent; after the oil agent is subjected to heating treatment for 2h at 200 DEG C, the heat weight loss is smaller than 15 weight percent; when the oil agent is 50+ / -0.01 DEG C, the movementviscosity is 27.5 to 30.1 mm<2> / s; after the oil agent is prepared into an emulsion with the concentration being 10 weight percent, the movement viscosity is 0.93 to 0.95 mm<2> / s; the oil film intensity of the oil agent is 121 to 127N. The preparation method is simple and reasonable; the prepared product has the advantages of softness, fine and smooth effect, good appearance and good texture.

Description

technical field [0001] The invention belongs to the field of fiber preparation and relates to a preparation method of polyester porous yarn. Background technique [0002] Since the appearance of polyethylene terephthalate (PET) fiber, it has developed rapidly because of its excellent performance, and its output has become the crown of synthetic fiber in the world. Polyester fiber has a series of excellent properties such as high breaking strength, high elastic modulus, moderate resilience, excellent heat setting performance, good heat resistance and light resistance, acid resistance, alkali resistance and corrosion resistance, and the fabric prepared from it has wrinkle resistance. And crispness and other advantages, so polyester fiber is widely used in clothing and home textiles and other fields. [0003] Due to the small dielectric constant, low moisture regain and high friction coefficient of most PET fibers, spinning oil must be used in the spinning process. The main c...
