As a further improvement on the present invention, carry out step 22 after it is characterized in that completing described step 21: mercerising.
As a further improvement on the present invention, it is characterized in that described step 3 comprises step 31: brighten;
As a further improvement on the present invention, it is characterized in that dyeing after mercerising.
As a further improvement on the present invention, dye after the enzyme treatment step.
The beneficial effect that the present invention adopts is: method of the present invention is applied to natural biodegradation industrially to avoid simultaneously destructive degradation reaction to continue to carry out.After having adopted method of the present invention, guarantee the service life of ramie fabric, improved the feel of ramie fabric, more obvious to the elimination of prodding and itching feeling, thus the comfortableness of wearing is provided.
The specific embodiment
Below the present invention is described further.
The biological afterfinish method of ramie fabric comprises the following steps:
Step 1: singe; Step 2: move back and boil; Step 3: gentle drawing; Step 4: preshrunk; Step 5: self-contained, also comprise the enzyme treatment step between described step 2 and step 3, described enzyme treatment step is as follows: add the cellulase RE-60 of 1.4-1.5%owf and the activator RJ-60 of 2-5g/l in jet overflow dyeing machine, the cellulase RE-60 in jet overflow dyeing machine and activator RJ-60 turned round one hour at 50-60 ℃ of temperature.
The present invention adopts different schemes according to different clothes, for shallow middle painting cloth, when carrying out described enzyme treatment step, add the cellulase RE-60 of 1.4%owf and the activator RJ-60 of 2g/l in jet overflow dyeing machine, the cellulase RE-60 in jet overflow dyeing machine and activator RJ-60 turned round one hour at 50 ℃ of temperature; For dark cloth, when carrying out described enzyme treatment step, add the cellulase RE-60 of 1.5%owf and the activator RJ-60 of 5g/l in jet overflow dyeing machine, the cellulase RE-60 in jet overflow dyeing machine and activator RJ-60 turned round one hour at 55 ℃ of temperature.
In order further to improve the quality of ramie fabric, comprise step 21 between described step 2 and enzyme treatment step: bleaching.
In order further to improve the quality of ramie fabric, carry out step 22 after completing described step 21: mercerising.
In order further to improve the quality of the ramie fabric that makes with shallow middle painting cloth, described step 3 comprises step 31: brighten;
In order further to improve the quality of the ramie fabric that makes with shallow middle painting cloth, dye after mercerising.
In order further to improve the quality of the ramie fabric that makes with dark cloth, dye after the enzyme treatment step.
In the inventive method, be one of key of the inventive method to the selection of cellulase, due to the production bacterial classification of the fine cellulase of difference, the mode of production different and vigor and composition product vary, therefore by experiment, determine to select cellulase RE-60, concrete experimental data is as follows:
Condition: equipment: jet overflow dyeing machine; Temperature: 50 ℃; PH value: 5.8; Bath raio: 1:15; Substrate: pure ramie mercerising semi-finished product; Time: 1 hour.
| Cellulase | RE-10 | RE-40 | RE-60 | RE-90 | RE-100 |
| Enzyme dosage %owf | 0.4 | 1.6 | 1.4 | 0.4 | 1.4 |
| Strength loss rate % | 40.0 | 45.0 | 27.8 | 33.8 | 34.6 |
| Stiffness degradation rate % | 26.0 | 21.0 | 38.6 | 31.7 | 35.6 |
| The pH scope of 90% vigor | 4.5-5.5 | 5.5-6.0 | 5.5-6.5 | 4.8-5.7 | 5.5-6.5 |
As seen from the above table, in the situation that the strength loss rate is identical, the stiffness degradation rate of the ramie fabric that process RE-60 enzyme is processed is larger, feel is more soft, elimination to prodding and itching feeling is more obvious, and has temperature, pH value sensitivity lowly, is convenient to the characteristics of industrial practical operation.
In the inventive method, the selection of activator is also one of key of the inventive method, because in cellulase carries out the catalyzing hydrolysis process to ramie, the impact of activator is very obvious, therefore by experiment, determine to select activator RJ-60, concrete experimental data is as follows:
As seen from the above table, RJ-60 and traditional acetic acid-sodium acetate comparatively speaking have and improve enzyme activity, stable pH range, prevent that cloth cover from sending out old, preventing the characteristics of staining.
The data that the present invention utilizes cellulase RE-60 and activator RJ-60 to turn round one hour in jet overflow dyeing machine are as follows:
Condition: temperature: 55 ℃; RE-60:1.5%owf; RJ-60:5g/l, bath raio: 1:15.
In sum, method of the present invention is applied to natural biodegradation industrially to avoid simultaneously destructive degradation reaction to continue to carry out.After having adopted method of the present invention, guarantee the service life of ramie fabric, improved the feel of ramie fabric, more obvious to the elimination of prodding and itching feeling, thus the comfortableness of wearing is provided.
