Embodiment 1
[0018] A process for keeping the freshness of reeling cocoons when the silk reeling machine is stopped, comprising the following steps:
[0019] 1) After the automatic silk reeling machine stops, drain the silk reeling soup in the silk reeling tank;
[0020] 2) mixing the glacial acetic acid with water to obtain an aqueous acetic acid solution with a concentration of 10% to 30% (V / V);
[0021] 3) Put the aqueous acetic acid solution obtained in step 2) into a sprayer, spray evenly on the remaining cocoons remaining in the silk reeling tank with the sprayer, and allow it to soak naturally for 15 minutes;
[0022] 4) Slowly add cold water at a temperature of 5°C at a flow rate of 500ml / min into the silk reeling tank until the silk reeling tank is full.
[0023] The deterioration and color change of reeled cocoons are divided into 3 grades: Grade 0: the cocoon body is completely white; Grade 1: slight yellowing; Grade 2: deep yellowing; Grade 3: extremely yellowing of;

Embodiment 2
[0027] 1) After the automatic silk reeling machine stops, drain the silk reeling soup in the silk reeling tank;
[0028] 2) mixing the glacial acetic acid with water to obtain a 20% (V / V) acetic acid aqueous solution;
[0029] 3) Put the aqueous acetic acid solution obtained in step 2) into a sprayer, and evenly spray it on the remaining reeled cocoons remaining in the silk reeling tank with the sprayer, allowing it to soak naturally for 20 minutes;
[0030] 4) Slowly add cold water at a temperature of 10°C to the silk reeling tank at a flow rate of 1000ml / min until the silk reeling tank is full.
[0031] In this way, do not add water to the silk reeling soup, directly add glacial acetic acid with an equivalent concentration of 20% to the silk reeling soup, and directly add glacial acetic acid to the silk reeling soup to reach a concentration of 20%, as shown in figure 2 Shown, the deterioration index method of embodiment 2 is all lower than all the other two methods, has be...
Embodiment 3
[0033] 1) After the automatic silk reeling machine stops, drain the silk reeling soup in the silk reeling tank;
[0034] 2) mixing the glacial acetic acid with water to obtain a 30% (V / V) acetic acid aqueous solution;
[0035] 3) Put the aqueous acetic acid solution obtained in step 2) into a sprayer, spray evenly on the remaining cocoons remaining in the silk reeling tank with the sprayer, and allow it to soak naturally for 15 minutes;
[0036] 4) Slowly add cold water at a temperature of 15°C at a flow rate of 1500ml / min into the silk reeling tank until the silk reeling tank is full.
[0037] This is compared with the 3000ml / min flow rate filling, 20 ℃ silk reeling tank environment, 6000ml / min flow rate filling, 25 ℃ silk reeling tank environment, for example image 3 Shown, the deterioration index method of embodiment 3 is all lower than other two kinds of methods, and flow rate adds water speed too fast and can affect the gradual dilution and the dispersal of the acetic a...
