Comparative example 1
The only difference from example 1 is that mechanical peeling was used instead of the peeling method of step (1), and the rest remained the same.
Comparative example 2
The only difference from example 2 is that the addition of magnesium dihydrogen phosphate and sodium glutamate in step (2) was omitted and the rest was kept the same.
Comparative example 3
The difference from the example 3 is only that nano zinc oxide with the particle size of 10-15 nm is used to replace the modified nano zinc oxide in the step (2), and the rest is consistent.
Comparative experiment
The same batch of wickers were used as a weaving raw material, the wickers were processed by the methods of examples 1 to 3 and comparative examples 1 to 3, respectively, and processed into samples (5 in each group) having a specification of 5 cm in length after processing, while peeled wicker samples without any processing were used as a control, and each group was dyed with reactive brilliant red X-3B (dyeing conditions were: dye concentration of 2%, dyeing temperature of 55 ℃, dyeing time of 100 minutes, fixation with a sodium chloride solution having a concentration of 30 g/l, fixation time of 30 minutes, bath ratio of 1: 20), after dyeing, each group of samples were subjected to a light resistance test (after dyeing, each group of samples were placed in an ultraviolet irradiation apparatus for irradiation, 15 measurement points were taken on each sample, measurement before and after each group of samples, an average value was taken, and after 180 hours of ultraviolet irradiation, color difference value change), the color difference values of all groups of samples are measured, independent variables in the preparation of all groups of test samples are kept consistent, and dyeing performance results are recorded as shown in the following table:
| item | Dye uptake (%) | Water contact Angle (°) | Color difference change value Delta E |
| Example 1 | 61.5 | 130.2 | 0.37 |
| Example 2 | 61.7 | 130.4 | 0.34 |
| Example 3 | 61.6 | 130.2 | 0.36 |
| Comparative example 1 | 59.8 | 107.5 | 0.65 |
| Comparative example 2 | 56.2 | 122.8 | 0.72 |

| Control group | 42.2 | 91.5 | 2.60 |
(wherein. DELTA.E represents no color difference trace in the range of 0 to 0.5, a slight difference trace in the range of 0.5 to 1.5, a visually perceptible color difference trace in the range of 1.5 to 3.0, a recognizable color difference trace in the range of 3.0 to 6.0, a large color difference trace in the range of 6.0 to 12.0, and a very large difference trace in the range of 12.0 or more.)
