摘要（英）：

A pretreatment process for MFPET fiber dyeing comprises an open-width desizing process and a machine-vat refining process. Each liter of an open-width desizing auxiliary used in the open-width desizing process comprises the following materials: 20 to 30 g of liquid caustic soda, 1 to 2 g of an emulsifying and dispersing desizing agent M, 1.8 to 2.2 g of sodium tripolyphosphate, and 1.8 to 2.2 g of a degreasing agent F; each liter of a machine-vat refining auxiliary used in the machine-vat refining process comprises the following materials: 3 to 5 g of sodium carbonate, 1.8 to 2.2 g of an oxidizing desizing agent D, 1.8 to 2.2 g of an oil cleaner 101, and 1.8 to 2.2 g of the degreasing agent F. According to the pretreatment process provided by the invention, the MFPET fiber dyeing effect can be better, and the dyeing fastness can be higher.
