Embodiment 1
[0046] Embodiment 1: a kind of preparation method of colored light body fiber, carry out according to the following steps:
[0047] (1), slice drying:
[0048] The moisture content in the slices must be reduced before spinning. Low-speed spinning requires the moisture content of the slices to be below 0.005%, while high-speed spinning requires the moisture content of the slices to be below 0.003%. The moisture content of the slices should be uniform and the amount of powder should be less;
[0049] (1), pre-crystallization hot air circulation system treatment:
[0050] The slices enter the pre-crystallization fluidized bed, and the air is blown into the slices from bottom to top through the mesh plate. The inclination angle of the mesh plate is 65 degrees, which takes away the dust in the slices. Each slice is fully exposed to the gas, and the heat transfer efficiency is high. During the crystallization process, the pre-crystallization is carried out uniformly and continuousl...
