008 : Master of Jaeya
“uh?”
Unknowingly, an exclamation came out.
It was because there was a structure like a distillation tower in front of me. It was a high-tech structure that did not suit this shabby factory at all.
‘Isn’t it a distillation tower? Come to think of it, the batch method is a bit old-fashioned.’
Upon closer inspection, the circular metal tubs were not integrated, but were separated from each other.
It was not a facility for distilling crude oil.
It felt like an experimental instrument for synthesizing high molecular compounds that could only have been used in the early 20th century.
“Who are you?”
“Hello, boss. It is called Woo Chan-soo of the trending unemployment. I came in after seeing the sign.”
Grandpa Heoyeon appeared out of nowhere, so I started by saying hello.
“I am not the boss. The boss is my son, and I am the security guard here.”
“Yes?”
Aren’t you in the mood for a security guard?
He was a grandfather with a very skinny body and sparkling eyes that felt beyond eccentric and even extraordinary.
“Anyway, what did you come for?”
“We are looking for a yarn company. I wondered if I could get nylon yarn here.”
“What, get nylon? Maybe it’s because he’s young, he does everything others don’t.”
“The signboard here says it’s a nylon specialty store, right?”
“OK got it. Now that you’re here, eat first. After that, go see Yonsa.”
“Yes?”
Grandpa saw me and told me to eat first.
Come to think of it, it was long past lunchtime.
“Why, don’t you want to eat in a place like this?”
“No, I don’t hate it…”
“Then go inside. It looks like I couldn’t even eat because I was walking around, but Mt. Geumgang is also an after-dinner view.”
The old man pushed me with a nonchalant gesture and entered the factory.
“Honey, who is that bachelor?”
“I don’t know, he said he was a merchant selling fabrics. They said they came to get nylon, but they didn’t eat.”
“I have to eat rice. It’s all about eating and living.”
“Don’t just talk, suddenly give me a seat.”
“Come here. If you are hungry, you will get sick.”
“Today is siraegi soup. I put some meat in it, so it should be good to eat.”
It seems to be a family-run factory.Read at noblemtl
Judging from the fact that an elderly couple and a young man with a similar face were sitting at the table, it seemed almost certain.
As for food, there was nothing special about it.
I put barley rice in a large bowl, topped it with all sorts of herbs and red pepper paste, sprinkled it with plenty of sesame oil, and rubbed it together.
If you put a full amount of such bibimbap in a bowl, you can eat it with soup.
It looked like a lot of sheep, but I went in endlessly, probably because I wandered around so much.
“It looks nice and eats well.”
“… Ah yes. It’s really good. thank you.”
gulp. gulp.
“Are you taming a newcomer? Where is the business meeting?”
“Yes?”
The man who appeared to be his son asked while pouring barley tea.
It seemed that the son the grandfather had talked about was this person.
“What yarn did your senior tell you to find? I wouldn’t have taught you the specifications, so just recite the specifications you want roughly.”
It seems that I looked like a new employee when I went looking for yarn.
In fact, in the 1960s and 1970s, it was common for each company to make new employees sell products under the pretext of education, to develop customers endlessly, to work part-time at agencies, and to buy insurance for affiliates. .
“It is a 120 denier nylon-cotton blend yarn. I want to get a variety of cotton blends from 10% to 45%.”
“Hmm… I learned it properly for a newcomer. I must have met a good senior.”
“What kind of yarn is handled here?”
“There is no yarn. When you have eaten, go back.”
“father!”
huh? I was talking to my son, but suddenly the grandfather next to me got angry.
It was absurd.
He said he was a security guard and cut off the conversation with the boss.
Even at the nylon yarn factory, there is no yarn.
The day was truly dynamic.
Buying food and getting a factory, learning how to smuggle at a Japanese company branch, and now being kicked out of the house where you got food.
“why? am i wrong? I can’t even spin the thread properly, so where’s the thing to sell?”
“I don’t know about 45% cotton blends, but I can sell 10% blends. I mean, the quality is fine.”
“It’s okay, what’s okay! Where do you sell yellowed and brittle nylon? Fuck them all.”
“Honey, if you say that, the guest will misunderstand you.”
The grandmother began to soothe the jumping grandfather. It was like watching an old sitcom.
“What a misunderstanding!! No matter how crazy the world these days is because of money, I can’t do that! nothing to sell good!”
Grandpa hit me on the butt and drove me out like chasing a chicken.
“Take Mother and Father. Come on.”
“Yes, I understand. Bachelor, don’t get me wrong. This old man has some senility.”
“It’s a misunderstanding, no.”
“Oh, no. i have to die soon I’m sorry, bachelor.”
Grandmother beat her chest and lamented.
It was hard to understand either why she wanted to die or why she felt sorry for me.
It was like watching an old comedy play.
“Why die if the owner dies?”
“I’m going to die because you’re such a jerk. Come on. Don’t interfere with my son’s business, come on!”
“Oh hey, this guy. Don’t let go of your arm.”
My grandmother took my grandfather somewhere, and my son looked at me with an embarrassed expression.
“Are you confused? Originally, my father gets angry easily over trivial things.”
“Ah, yes. I understand.”
“By the way, my father graduated from the Department of Mechanical Engineering at Gyeongseong Vocational School.”
“You are an engineer.”
Wow, he was quite an inspiration.
Wasn’t Gyeongseong Vocational School one of the few higher education institutions during the Japanese colonial period?
At that time, it was a place that attracted the best talents in the fields of architecture/mechanics/electricity/civil engineering/railway.
“Yes, he is skilled enough to make his own with this nylon polymerization. All I could see was over my shoulder at the Japanese factory.”
‘yes? Was this structure a nylon polymerization furnace?’
It somehow resembled a crude oil still, but it was a polymerization furnace.
Petrochemical machines seem to have something in common.
Anyway, the fact that my grandfather was a genius was surprising, but it was even more surprising that he imitated the nylon polymerization furnace with only his eyes.
‘I guess this is really the early stage of Hyesung Group?’
It is quite famous that the head family of Hyesung Group are all engineers.
As the textile business declined in the late 20th century, the group’s business declined, but at one time it was a good group.
“Do you spin nylon yourself in this factory?”
“Yes, I make a lump of nylon with this equipment and spray it with a spinning machine there to pull out the yarn. When making blended yarn, cotton is purchased separately and twisted with our nylon to wind the final yarn.”
Although the nylon was not caught on the equipment, he explained the thread pulling process with hand gestures.
It was not a skill I had explained to customers once or twice.
It was like a boss.
“Can I see some samples?”
“Come this way.”
We went further into the factory.
It was neat and tidy, but there was no equipment that was running.
Yarn samples also looked like they had been spun before.
“Has it been a long time since you picked it? It looks like the nylon yarn is discolored.”
The nylon, which should be silvery white, was a bit grainy.
It’s like being hit.
“It’s not discoloration, it’s just our product.”
“The original color is like this?”
“This is because our polymerization technology is still lacking. That’s why my father said he had nothing to sell.”
The president’s face turned red as he explained, as if he must have been humiliated by the buyer.
Still, I believed rather than lied.
“Is it okay if I dye my hair?”
“If it is a dark color, there is no problem, but if it is a light color, the saturation is not very good. If you buy it, I can set the price to 150 won per pound.”
If it’s 150 won per pound, the exchange rate is 270 won… Huh, I don’t think 60 cents a pound would be enough?
pretty cheap?
“It’s cheaper than Gabonane products.”
“Yes, since we polymerize it ourselves, even if we sell it, there is still a little bit left over. Haha… Anyway, even if you don’t know how to dye, you should try beforehand to see how often it breaks when weaving.”
He was a very conscientious gentleman.
Even though he put on a puzzled expression, he confessed that his yarn cuts well.
“Looks like it cuts better than thread.”
“Yes, I admit. No matter how different the conditions for twisting, I couldn’t keep up with the strength of the thread.”
“If you are a speaker, are you twisting yarn?”
“you’re right. What you see over there is a repeater. Have you ever had a baby? Threads, like straw, become stronger when twisted together.”
The boss rubbed both hands together and gestured for the baby.
It was strange. Shouldn’t you twist the thread that way?
I don’t know how to twist a baby, but I know how to twist a thread.
In construction, steel wire cables used when erecting suspension bridges are made by twisting steel wires, and submarine cables used in plants are made by twisting outer sheaths.
These are things that should never be cut off, so you should never twist them like a baby when making them.
This is because, if twisted like a baby, the strength of the steel wire or the sheathing material decreases over time due to the restoring force that tries to return to its original state.
To make the wires right, you need to put one wire in the center to make it the center, and then wrap the other wires around it, rather than twisting them together.
There must be at least one central string so that it does not loosen or lose strength over time.
If even that is not enough, heat is applied when winding.
“Is this equipment also copied with keen eyes?”
“Yes, my father made it himself.”
While it was great to make this by hand, it lacked the core know-how.
“Do you think you can solve the thread strength problem?”
“yes?”
“Walk a thread. I’ll take care of the equipment.”
“You see my hands?”
“Haha, don’t worry, I won’t break it.”
I pulled a piece of yarn from the twisting disk of the twister.
This thread will hold the center.
Whether it’s a person or a thread, you have to raise your hand and say ‘Standard!!!’ to clean up the surroundings.
It was so simple that it seemed to have eluded my grandfather’s attention.
The boss tilted his head, but I motioned him to turn the equipment.
Weiying.
“That’s enough.”
“Have you seen all of these hands?”
“sure. That’s all.”
I pulled out the twisted thread and handed it to the boss.
He made a puzzled expression when I handed him the thread, and after pulling the thread a few times, he trembled.
After pulling on it several times, I even cut it off with my teeth as if I couldn’t believe it.
“What? What kind of magic did you do?”
“It’s not magic. It’s just a logical approach. You have to put one thread in the center and twist it to make it properly twisted. If you rotate all the threads, they will come undone easily.”
“ah! I see! this…”
The more my words continued, the more exclamation the president gave.
“If the strength is not enough, try applying heat. It might be enough to raise the temperature of the drum to hang the thread on.”
“You were a doctor. I didn’t know.”
“Not even a doctor.”
I am not a doctor, but an engineer who has been through all of the 21st century birth and death, so I know it to some extent.
“Would you like to run the nylon polymerization furnace? I think I can help.”
“Yes, of course.”
The boss got excited and ran.
I put the powder material into the stopped polymerization furnace, raised the temperature, and pressed various buttons.
It seemed to be done manually from one to ten, but it was quite a skill.
After watching for a while, when I felt that the polymerization furnace was getting hot, nylon flakes poured out like cheap cereal.
The nylon flakes, which should have been transparent silvery white, were mixed with each other. I spun yarn with these flakes, so it’s that kind of color.
The reaction rate seemed to be set too high.
Basically, this facility seemed to follow the method of polymerization, extraction, and drying.
It was a very basic plant, and it seemed that only the catalysts and reaction control materials needed to be optimized.
“I will ask you a few questions. What catalyst do you use?”
“A catalyst?”
“Do you just raise the temperature during polymerization?”
“Yes, pour caprolactam powder, a raw material for nylon, mix acetic acid and water properly, hold at 150 degrees, then 190 degrees for a while, then heat it all the way up to 260 degrees and cool it down slowly.”
The president even recited the polymerization conditions to me.
These process conditions are no different from confidential, but they trusted me and told me.
“You use acetic acid. Then, what kind of reaction stabilizer do you use?”
When acetic acid was used as a reactive agent, it made pure water, so there was no possibility of discoloration.
Then the culprit of discoloration had to be a reaction stabilizer.
“A reaction stabilizer?”
“Looks like it starts to react when you raise it from 150 degrees to 190 degrees, and then you need to add a stabilizer.”
We often use the word ‘reaction is explosive’, but that’s all from chemical plants.
Contrary to good intentions, in fact, if the reaction occurs rapidly in the industrial field, it is not only dangerous, but also interferes with obtaining materials of uniform quality, so the reaction rate must be intentionally lowered.
The material used at that time is a so-called reaction stabilizer.
“Mo… I didn’t know. No other ingredients are mixed in between.”
There is no concept of a reaction stabilizer.
This was also the result of a lack of basic knowledge.
“like. Then mix in some titanium oxide powder. Mix in about 0.5% of the total weight.”
If you do not know what to use as a reaction stabilizer, you can add titanium oxide.
It mixes well with any substance, has excellent heat resistance, and acts as a filter to filter out organic impurities due to the nature of oxide.
To be precise, 0.1 mol% must be added considering the chemical formula, but this small amount of plant can be approximate.
“Titanium oxide?”
“If you search the drugstore, you should be able to find it easily.”
“All right. I will definitely get it and try it out.”
The voice of the young boss was full of hope.
How come, it looks like you got some nylon yarn?
And at a lower price than Japanese contraband.
