Table 1, comparison of the dyeing properties of non-pretreated acetocyan fibers with different pretreated fibers.
| Sample (I) | K/S |
| Without pretreatment | 6.4165 |
| Individual ionic liquid treatment | 6.8543 |
| Nitrilase treatment alone | 7.0157 |
| Combined pretreatment of ionic liquid and nitrilase | 8.6242 |

Example 2: influence of the dosage of the ionic liquid on the dyeing performance of the acetocyan fiber.
A method for dyeing cellulose acetate fibers by berberine comprises the following steps:
step a, pretreatment process: the mass fraction of the allyl-3-methylimidazolium chloride ionic liquid is 80-95%, and the bath ratio is 1: treating at 45 deg.C and 60 deg.C for 30min, taking out sample, washing with anhydrous ethanol for 3 times, and washing with water. ②, the nitrilase dosage is 6% owf, the pH is 7.0, the bath ratio is 1: treating at 40 and 45 deg.C for 30min, washing with water, and oven drying.
Step b, dyeing process: berberine is used in 3% owf, pH is 4, bath ratio is 1: and (3) dyeing at room temperature, heating to 90 ℃ at the temperature of 1 ℃/min, keeping the temperature for 60 minutes, washing with water, and drying.
By adopting the process, the dosage of the I-allyl-3-methylimidazolium chloride ionic liquid is adjusted, and the influence on the dyeing property of the acetocyan fiber is tested, and the result is shown in table 2.
Table 2 effect of ionic liquid dosage on dyeing performance.
| Amount of Ionic liquid (%) | K/S |
| 80 | 8.3881 |
| 85 | 8.5414 |
| 90 | 8.6242 |
| 95 | 8.6611 |
As can be seen from table 2: within a certain range, the K/S value is increased along with the increase of the dosage of the ionic liquid, and the color yield is increased. When the dosage of the ionic liquid is more than 90%, the dosage is continuously increased, the change of the K/S value is not large, economic factors are comprehensively considered, and when the dosage of the ionic liquid is 90%, the effect is optimal.
Example 3: the influence of the amount of nitrilase on the dyeing properties of acetocyan fibers.
A method for dyeing cellulose acetate fibers by berberine comprises the following steps:
step a, pretreatment process: the mass fraction of the allyl-3-methylimidazole chloride ionic liquid is 90 percent, and the bath ratio is 1: treating at 45 deg.C and 60 deg.C for 30min, taking out sample, washing with anhydrous ethanol for 3 times, and washing with water. ② the nitrilase dosage is 4-10% owf, pH is 7.0, bath ratio is 1: treating at 40 and 45 deg.C for 30min, washing with water, and oven drying.
Step b, dyeing process: berberine is used in 3% owf, pH is 4, bath ratio is 1: and (3) dyeing at room temperature, heating to 90 ℃ at the temperature of 1 ℃/min, keeping the temperature for 60 minutes, washing with water, and drying.
The above process was used to adjust the amount of nitrilase used and to test its effect on staining performance as shown in table 3.
TABLE 3 influence of nitrilase dosage on the dyeing properties.
| Nitrilase amount (% owf) | K/S |
| 4 | 7.9154 |
| 6 | 8.6242 |
| 8 | 8.7645 |
| 10 | 8.8713 |
As can be seen from table 3: the K/S value increases with increasing nitrilase dosage, and the color yield does not change much when the nitrilase dosage exceeds 6% owf.
Example 4: the influence of the berberine amount on the dyeing performance.
A method for dyeing cellulose acetate fibers by berberine comprises the following steps:
step a, pretreatment process: the mass fraction of the allyl-3-methylimidazole chloride ionic liquid is 90 percent, and the bath ratio is 1: treating at 45 deg.C and 60 deg.C for 30min, taking out sample, washing with anhydrous ethanol for 3 times, and washing with water. ② the nitrilase dosage is 6% owf, pH is 7.0, bath ratio is 1: treating at 40 and 45 deg.C for 30min, washing with water, and oven drying.
Step b, dyeing process: the berberine is used in 1-7% owf, the pH value is 4, the bath ratio is 1: and (3) dyeing at room temperature, heating to 90 ℃ at the temperature of 1 ℃/min, keeping the temperature for 60 minutes, washing with water, and drying.
The above process was used to adjust the berberine dose and test its effect on staining performance as shown in table 4.
Table 4, effect of berberine dosage on staining performance.
As can be seen from table 4: with the increase of the using amount of the berberine, the K/S value is increased, and the color yield is increased. The specific dosage is determined according to the required color depth during dyeing, and the required berberine dosage is small during dyeing of light color; when the color is dyed in dark color, the consumption of the berberine is large.
Example 5: influence of dyeing pH on dyeing properties.
A method for dyeing cellulose acetate fibers by berberine comprises the following steps:
step a, pretreatment process: the mass fraction of the allyl-3-methylimidazole chloride ionic liquid is 90 percent, and the bath ratio is 1: treating at 45 deg.C and 60 deg.C for 30min, taking out sample, washing with anhydrous ethanol for 3 times, and washing with water. ② the nitrilase dosage is 6% owf, pH is 7.0, bath ratio is 1: treating at 40 and 45 deg.C for 30min, washing with water, and oven drying.
Step b, dyeing process: the berberine dosage is 3% owf, the pH value is 3-11, the bath ratio is 1: and (3) dyeing at room temperature, heating to 90 ℃ at the temperature of 1 ℃/min, keeping the temperature for 60 minutes, washing with water, and drying.
The above process was used to adjust different pH and test its effect on staining performance as shown in table 5.
Table 5 effect of dyeing pH on dyeing performance.
| pH | K/S |
| 3 | 8.6723 |
| 4 | 8.6242 |
| 5 | 8.6049 |
| 7 | 8.6352 |
| 9 | 8.0116 |
| 11 | 6.4384 |
As can be seen from table 5: the dyeing pH values are different, the change of the K/S value is large, and the color yield is large under the acidic condition; under alkaline conditions, the color yield is reduced, and the color light is changed, which is caused by the change of the molecular structure of the berberine under alkaline conditions.
Example 6: the effect of different dyeing temperatures on dyeing performance.
A method for dyeing cellulose acetate fibers by berberine comprises the following steps:
step a, pretreatment process: the mass fraction of the allyl-3-methylimidazole chloride ionic liquid is 90 percent, and the bath ratio is 1: treating at 45 deg.C and 60 deg.C for 30min, taking out sample, washing with anhydrous ethanol for 3 times, and washing with water. ② the nitrilase dosage is 6% owf, pH is 7.0, bath ratio is 1: treating at 40 and 45 deg.C for 30min, washing with water, and oven drying.
Step b, dyeing process: berberine is used in 3% owf, pH is 4, bath ratio is 1: dyeing at room temperature, heating at 1 deg.C/min, maintaining at 70-100 deg.C for 60 min, washing with water, and oven drying.
The above process was used to adjust different temperatures and test their effect on dyeing performance as shown in table 6.

| Dyeing temperature (. degree.C.) | K/S |
| 70 | 6.7051 |
| 80 | 8.1873 |
| 90 | 8.6242 |
| 100 | 8.4319 |
As can be seen from table 6: and (3) further increasing the K/S value with the increase of the dyeing temperature, and continuing to increase the temperature until the K/S value is maximum under the dyeing condition of 90 ℃, so that the color yield is slightly reduced.
