Production process of high-shrinkage polyester wool-like fiber

The invention relates to the technical field of wool-like fiber production, and particularly discloses a high-shrinkage polyester wool-like fiber production process, which comprises the steps of raw material treatment, esterification reaction, condensation polymerization, cast strip pelletizing, soaking shrinkage and blending, silk yarn flowing out of the spinning machine enters a thermal shrinkage box containing hot water to be soaked and shrunk by the length of 0.5%-2%, then the silk yarn is stretched evenly on a shifting fork type flat roll drafting machine, and the high-shrinkage polyester fiber is obtained. The high-shrinkage wool-like polyester fiber produced through the technology can be blended with wool, cotton and the like or interwoven and blended with other kinds of yarn; and after post-treatment, the high-shrinkage fibers are shrunk, so that the hand feeling of the fabric can be effectively improved, and the fabric has better elasticity and full hand feeling at the same time. 本发明涉及仿毛纤维生产技术领域，具体公开
