After the space dyeing is finished, the space dyeing cone yarns are sequentially subjected to hot water washing, dehydration and drying treatment: the hot water washing temperature is 95 ℃, and the water washing time is 25 min; dehydrating the cheese washed by hot water on a drying machine, wherein the rotating speed of the drying machine is 6800r/min, and the drying time is 15 min; and (3) drying the dewatered space-dyed yarns by hot air at the drying temperature of 110 ℃ for 1 h.
The yarn produced by the space dyeing method is in a space dyeing style, and the color nodes of the dyed yarn are circularly changed according to the specific steps of red 1cm + white 12cm + yellow 1cm + white 12cm + blue 1cm + white 12cm + black 1cm + white 12cm + red 1cm + white 12cm + black 1cm + white 12cm + blue 1cm + white 12cm + yellow 1cm + white 12 cm.
The space dyeing cone yarn yarns in the examples 1-2 were subjected to color fastness test by using a rubbing fastness tester and a soaping fastness machine, and the test results are shown in table 1.
TABLE 1 color fastness test data for multicolored space-dyed cheese
As can be seen from Table 1, the various fastnesses of the space-dyed yarns prepared by the examples 1-2 of the present invention all reach 3-4 levels or more.
