Now when I walk down the street and look around from house to house, I see that the yard of every house is full of wheat straw, and I can tell that I have gained a lot from it.
Although the labor efficiency is low, we are busy threshing wheat during this cold season, and we don’t have to worry about everything when we have food.
Lin Yan felt a lot more relaxed. The food problem had finally been solved initially. As long as people didn't starve, people would have the energy to do other things.
The tung oil fruit has been sent to the laboratory, and a small set of tools for the Ye Zi family's oil mill has been prepared, and Maomu is Lin Yan's helper in pressing the oil.
After the dried tung oil seeds are pressed, the oil yield is very high. After dozens of kilograms of oil are squeezed, the remaining tung oil seeds are kept until needed.
Mao Mu looked at Lin Yan using a brush to apply tung oil to the wood, "Does this make it waterproof?"
"It should be, just apply a layer and let it dry and try the effect. If it doesn't work, apply a few more layers of oil."
This is the first time a test has been conducted to determine the waterproofing properties of tung oil.
Tung oil dries easily, and the oiled wood board dries quickly and feels much smoother. Mao Mu put the wooden board in the water and observed that it really did not seep.
And when the water was poured on it, there was no residue and it was slippery. He was pleasantly surprised and said, "It's really good. I only applied a layer of oil and the effect is so good."
Lin Yan checked it carefully and said, "It is indeed good. The quality of this tung oil is good, and the effect is visible after just one layer of application. But the smell is a bit strong, and it needs to be dried more to dissipate the smell."
"The smell will disappear after a while. The most important thing is that it is waterproof and the effect is very good. It can be used on existing wood products. It is simple and easy to operate, and it is very useful."
"There is still a shortage of tung oil seeds. We need to prepare more next year."
The two of them were muttering to each other, and Shi Zhi took time out of his busy schedule to come over and take a look, and was also amazed. "It's just a layer of oil, but the effect is so obvious. Lin Yan, every boat you make needs to be painted, so you won't be afraid of water leaks."
Lin Yan nodded, "I thought so too. Why did you come here suddenly?"
"I heard that you are doing a test on tung oil, so I came over to take a look. It's going to get cold soon. I want more people to go to wood factories and smelting plants to make accessories for frame cars, so that more cars can be used next year. You said you want to Don’t you want to tell Alan and the others?”
"Just tell Bai Yun, she is in charge of the wood factory and smelting plant. It is up to Bai Yun to decide whether to report to the arbitration tribunal or not."
"Okay, then I'll go find Baiyun."
As soon as Shi Zhi left, Bai Chen came, and she also came to see Tung Oil. After seeing the effect of brushing wood with tung oil, she asked, "Can the paper also be coated with a layer of oil so that it can be waterproof?"
"Theoretically, it's feasible. But how to do it, you have to figure it out slowly. I'll leave the oil paper to you. Just tell Hong Ling by the way, and the oil cloth will be handed over to her."
"Okay, I heard that Hong Ling has made new cloth, why don't we go and see it together?" Bai Chen also hadn't seen Hong Ling for several days.
Lin Yan asked curiously: "Is it still Azabu?"
"It should be. I heard it is very fine and whiter. She is preparing to dye the cloth."
"Dyeing? Are you sure?" Lin Yan was surprised. Has Hong Ling already achieved this step?
Bai Chen shook his head, "You'll know after you go and see."
Lin Yan thought about it and was not in a hurry. The effect of tung oil is very good. There are still many things to do next, and it can't be done in a short while. Why not go and see Hong Ling's progress.
She said: "Mao Mu, Bai Chen and I are going to Hong Ling's place, are you going?"
Mao Mu shook his head. He was not interested in the cloth. "You go ahead. I will continue to apply oil and see the effect."
The two came to the garment workshop, and Hongxiu welcomed them in with great enthusiasm, "I'm so happy that you can come. I will stay at my house for dinner today, and I will make dry noodles, so you can eat together. Speaking of this, Lin Yan would like to thank you very much, your mother-in-law didn’t hide anything, she told you all the ways to make pasta, and our family also benefited from it."
Thinking about the wheat that filled two rooms at home, Hongxiu smiled brighter and no longer had to worry about food.
Their family has already agreed to open up wasteland and plant more wheat in January next year.
Lin Yan said hurriedly: "I don't dare to take credit. Everyone grows so much wheat just for eating. The more varieties you can eat, the better."
Hongxiu insisted: "You are kind-hearted. If you have any good food, you think of everyone and everyone knows it. After having wheat, the family has enough food and no longer needs to go hungry. This is all due to you." "
"Hong Xiu is right. We all know Lin Yan's sacrifice and keep it in our hearts." Bai Chen agreed with a smile, "Let's find Hong Ling. Where is she?"
"Hong Ling, she has been rushing into the workshop for several days. You wait, I will call her."
"No, let's go and take a look together." Lin Yan said hurriedly.
Following Hong Xiu to the place, there were threads and cloths everywhere and it was very messy. Hong Ling was staring at a vat.
Hong Xiu said loudly: "Hong Ling, look who's coming."
Hong Ling turned around and saw Lin Yan and Bai Chen. She was surprised and said, "Why are you here? Wait for me for a while. I'll be fine soon."
"You go about your business. I heard that you are dyeing cloth, so we will come and take a look." After Lin Yan finished speaking, he looked at Hong Xiu, "You go and do your work, don't worry about us."
Hongxiu didn't stay either, telling them not to leave in a hurry and to have dinner at home before turning around and going about her own business.
Looking at the dark liquid in the vat, Lin Yan asked, "Is this going to be dyed black? What kind of dye did you use?"
"This is a dye made from steamed chestnut shells and filtered. I have just started trying it, and I haven't dyed the cloth yet." Hong Ling had heard Lin Yan mention dye before, and recently started trying it, but it has not yet produced any results.
"It's okay. We both came here on a whim. We thought of you and came over to have a look. You still need to study the dyeing of cloth yourself, and we can't help you much." Lin Yan said truthfully.
It has been a long time since she opened the room in the science and technology museum. She has not been out in the past two years, and her contribution has almost stagnated. She can only slowly explore everything by herself.
When this cold season passes, I still need to go out more and try to open more rooms and get more technical information.
I watched Hong Ling put a small piece of linen cloth into the dye vat and take it out after a while. The cloth did change color, but it faded badly after being soaked in water.
The red spirit infects the fabric again, repeating itself endlessly.
Lin Yan wondered: "The color of the cloth dyed in this way will fade after washing."
"Yeah, I'm trying to figure out how to make the dye adhere to the fabric and not fade. Just infecting it won't work. There should be some steps and additives. I'm looking for it."
Lin Yan encouraged, "Then keep working hard. I'm here to tell you that once the tung oil is squeezed out, I'll leave it to you how to make oilcloth."
"Oilcloth?" Hong Ling was stunned and looked at Lin Yan in confusion.
"It is a kind of cloth that is waterproof, moisture-proof, and moisture-proof. It can be used to keep out the rain on rainy days. It is easy to scrub. Generally speaking, just soak the cloth in tung oil. You can try it."
Hong Ling understood. "If we have oilcloth, we can make umbrellas, raincoats, etc., right?"
Lin Yan nodded, "That's it. Try making it when you have time. The tung oil is in the laboratory. Go and get it if you need it."
Hong Ling nodded.
While several people were talking, Hongxiu came and called them to eat. Lin Yan and Bai Chen had no choice but to stay and have a meal.
