A week or so, because it's about to break out of the cocoon.
-
The soil method should first peel off the cocoon, peel off the messy silk on the surface of the cocoon, and then divide the neat cocoon into color. After dividing the texture, you can put the cocoon into the boiling water, and continue to heat it until the cocoon is transparent enough to see the chrysalis inside, and then you can use chopsticks to pick up the silk head. The thread end is put on the ** wheel, and the rolling thread wheel can continuously pull off the silk.
In order to draw the silk without threading, some alkali should be put in the boiling water to reduce the mutual adhesion between the silk as much as possible.
On Wednesday, I boiled water at home, peeled four cocoons, and the filaments that were drawn were fine, but the strength was good. It's just that I just started to learn to draw silk, and the silk that was drawn out was pulled out together in several strands, because the messy silk outside the cocoon was not peeled clean, so that multiple strands were drawn together when the silk was drawn, and the silk of the three cocoons was finished in a while. The last cocoon was still pulled to the end, but it was broken four or five times, and it seems that the matter of pulling the silk is really a technical job.
In the process of peeling off the cocoon, my aunt came to play and talked about the silk, only to know that my grandmother had done silk work, but unfortunately my grandmother passed away in 1997, otherwise I really have to ask for advice. If you want to extract all the silk from these 400 cocoons, there should be a lot, but it is impossible to do anything with the silk extracted, and Wu Jiang's cocoon collection time will not be until June, so he has to try to save the cocoons by himself. The cocoon has been set for ten days, and if the temperature is not low, the moth will soon appear, and the cocoon will be useless.
Preserving this cocoon has become a problem that must be solved, killing the silkworm pupae is very important, the usual practice is to dry in the scorching sun, the silkworm pupae can be killed, but it has been raining heavily these days, it is impossible to use this method. There is no way, but to put the cocoon in the freezer of the refrigerator, so that the low temperature of minus 10 to kill the cocoon, presumably such a low temperature will be able to kill the silkworm chrysalis and preserve the purpose of the cocoon, but I don't know if this method will affect the quality of the silk.

Generally, it is windy in spring.
Kites are the best, and here are some of the conditions for the best time to fly kites:
When the wind is strong, it is more appropriate to enlarge the kite, and when the wind is small, it is more suitable to fly a small kite. In general, the higher above the ground, the stronger the wind. If the wind is about 2 meters above the ground, and the kite can't be put up, you can drag the kite to run in the wind for a while, and wait until the kite flies to a certain height and the wind is suitable, so you don't have to run, and the kite can't fall.
2.The direction of the kite's flight in the air is closely related to the wind force and direction. The wind speed and direction are fixed, and the kite is stable in the air; When the wind speed and direction change, the direction of the kite's flight in the air changes.
The changing wind direction and wind speed can make the dragon kite shake its head and tail, meandering and circling, majestic; It can make the eagle kite look forward to pitching and soaring up and down like a living eagle.
