Time passed slowly, and everything in Daming was moving forward step by step.

At the end of August of the first year of Ankang, good news came from the chemical test site of Dashiguo.

The rayon requested by Zhu Jingyuan was finally trial-produced.

After Zhu Jingyuan received the news, he immediately led the team to the experimental base to check it out, just like last time.

Lu Xueqin, the person in charge of the experimental base, took a strand of filament and introduced it to Zhu Jingyuan with some excitement:

"Your Highness, this rayon is twice as strong as cotton and five times as strong as wool.

"The point is that the abrasion resistance is particularly strong, ten times more abrasion resistant than cotton, and twenty times more abrasion resistant than wool.

"Clothes made of it are definitely more durable than any cotton wool material, and it is especially suitable for workwear.

"The disadvantage is that it is not absorbent in water, so if it is used as summer clothes, it is easy to get soaked in sweat.

"But if you look at it the other way, it's actually an advantage, because they're very easy to dry.

"And they're actually a western front made of plastic, so they shouldn't be moldy."

Zhu Jingyuan took the bundle of filaments and gently twisted them with his hands, and he was also quite excited:

"Okay, okay, then try to make clothes, not only clothes, but also bags and backpacks......"

The "rayon" that Lu Xueqin made is the nylon of Zhu Jingyuan's previous life, also known as nylon, or polyamide fiber.

This is the world's first "fossil material synthetic fiber".

It is not the first "synthetic fiber", nor is it the first "chemical fiber".

Prior to this, there were "viscose fibers" made from natural fibers such as cotton and linen, and viscose fibers were the earliest chemical fibers.

Including rayon, as well as later generations of modal, celier, bamboo charcoal fiber and other materials, the essence is this viscose fiber.

Compared with natural recycled fibers, the advantages of polyamide, a synthetic fiber made of fossil materials, are that the cost is lower, the production process is shorter, and the overall fiber is more environmentally friendly......

The first few points are actually relatively easy to accept, and the fact that it is more environmentally friendly may be difficult for many people to understand.

But the logic is actually very simple, rayon, modal, bamboo charcoal, tencel, ice silk are all "recycled fibers".

This "regeneration" process, which is the process of extracting natural cellulose, requires the use of chemical solvents containing acids, alkalis, and amines to completely dissolve it, so it causes additional pollution compared to virgin cotton and linen materials.

Nylon, a synthetic fiber made from fossil raw materials, is produced directly from oil dug up from the ground, avoiding the water, pesticides and fertilizers consumed in the process of plant cultivation.

Synthetic fibers crush natural fibers in terms of strength and abrasion resistance.

Chemical fiber clothes are only scratched and burned, but they are not worn, and they are top ten pieces in terms of wear-resistance.

The key is that when Zhu Jingyuan sees nylon known as "rayon" now, he has an inexplicable sense of intimacy in his heart.

Now the development level of this world is really getting closer and closer to the era in which I lived in my previous life.

Zhu Jingyuan and Lu Xueqin studied these "plastic silks", determined their official names as "rayon", and registered trademarks.

Let them continue to prepare factory production schemes, try to use them in the textile industry and try to make garments.

At the same time, research on elastic yarn continued.

Nylon itself also has a certain elasticity, but it is still relatively low overall, and can only be stretched by about five percent.

Elastic yarn is a polyurethane fiber, also known as elastic fiber, lycca, spandex, which can be stretched to six times its length.

With the direction pointed out by Zhu Jingyuan, the progress of related research is also very fast.

By October of the first year of Ankang, the elastic fiber material called "elastic silk" was successfully trial-produced.

Compared with rayon nylon, the effect of elastic silk is magical.

Never before has mankind ever used a conventional textile material with such a huge elasticity.

In the past, natural fibers, such as cotton, linen and wool, were basically inelastic, and the elasticity of silk was also very small.

The rubber bands used in elastic bands cannot be made into fine silk threads and cannot be used directly to weave fabrics.

It can only be wrapped with cloth and used as a tightened edge for belts, cuffs, etc.

Stretch yarn can be used directly as a textile material to weave a lightweight fabric with elasticity as a whole.

Stretch fabric, which is already a matter of course for modern people, is a very amazing thing at this time.

Therefore, when the synthetic elastic yarn was successful, even the craftsmen in charge of research and development themselves were surprised.

Lu Xueqin took a bundle of silk threads, stretched them outward several times, and after letting go, they immediately returned to their original state:

"Your Highness, this synthetic silk is really amazing, it can be made thinner than silk, and it has the elasticity of rubber bands, and it is more tough than rubber bands......"

Zheng Fuguang next to him also widened his eyes, he knows mechanics, but he doesn't understand polymer chemistry:

"How the hell is this done? Why is this filament so elastic? ”

The maidservants who followed Zhu Jingyuan, as well as the soldiers who accompanied them to protect them, were also extremely surprised now, and they all looked at the things in Lu Xueqin's hands in disbelief.

Zhu Jingyuan was also very emotional, the elastic material was finally made.

Modern body-fitting socks, gloves, underwear, and other clothes can finally be made.

The biggest problem with chemical fibers is that they usually don't absorb much water, but they can be blended with natural fibers.

All kinds of modern elastic clothing are basically added with elastic silk spandex

After everyone's initial admiration and surprise passed, Zhu Jingyuan once again arranged tasks for the person in charge here.

Rayon and stretch yarns, also known as nylon and spandex, are not usually used directly.

Instead, the two are combined in specific proportions, or with other fibrous materials, twisted in a special way to form a new hybrid yarn, which is then used in textile fabrics.

The so-called stretch cotton, corespun yarn and so on are all made in this way.

Those recycled fiber materials such as modal, ice silk, and tencel must also be blended with spandex if they want to gain elasticity.

Therefore, in the modern textile industry, elastic yarn spandex is very widely used.

With spandex, stockings in the modern sense can finally be made.

Stockings are purely petrochemical industry products, and basically only two materials, nylon and spandex, are used.

That is, the "rayon" and "elastic silk" made by Zhu Jingyuan's petrochemical experimental base.

This thing seems simple, but in fact it involves the entire oil extraction, smelting, chemical industry, and textile industry system.

Of course, the synthetic fiber industry was not born for stockings, which are just a by-product.

In fact, many things in modern times are like this, and the seemingly ordinary and inconspicuous little things can only be produced by relying on the extremely complex and huge industrial system.

From this point of view, the vast majority of countries in the world in the new century will not be able to produce even a pair of stockings.

Including the vast majority of the so-called developed countries......

Now, the two most important materials in synthetic fibers have been successfully developed, and Zhu Jingyuan has once again announced that he will pay bonuses to all relevant craftsmen and everyone will be paid another year's salary according to the original agreement.

No one doesn't like more wealth, and no one doesn't like to be affirmed for their work.

After Zhu Jingyuan's announcement was passed on, the atmosphere in the entire experimental base became extremely warm again.

Zhu Jingyuan stayed in the experimental base for half a day, and let the craftsmen of the petrochemical experimental base take another holiday to rest, and he and Zheng Fuguang and others returned to the palace.

Then Zhu Jingyuan summoned the main ministers of the Great Food Country, craftsmen from various laboratories and factories to a meeting.

Zheng Fuguang and Liu Zhixin followed Zhu Jingyuan to the petrochemical base, and they could probably guess what Zhu Jingyuan was going to do.

After everyone arrived, Zhu Jingyuan said directly:

"Rayon and stretch yarn are two synthetic materials that are enough to support a whole new textile industry.

"So I decided to officially start the comprehensive development and construction of the petrochemical, textile, and garment industries of the big food country."

Zhu Jingyuan paused slightly at the beginning, looking at the ministers and craftsmen around him, wanting to hear their opinions.

Liu Zhixin, the left chief of the Great Food Country, is the oldest and most sincere one in this group of people.

Hearing Zhu Jingyuan's thoughts, Liu Zhixin, who had already made some preparations, said with some worry:

"Your Majesty, the local population of our big food country is still too small, and the limited petrochemical industry is the limit.

"The textile and apparel industries require a lot of labor and adequate water.

"The place where we eat big food is basically not suitable for the development of this ......"

Petroleum extraction and chemicals are capital-intensive machines that require high investment to build infrastructure.

There is a high demand for labor, but it is not particularly sensitive to the price of labor, and it can directly attract immigrants at a high price.

Textiles and garments are purely labor-intensive industries that require cheap labor.

Zhu Jingyuan was also prepared for this, but he didn't speak immediately, wanting to continue to listen to opinions.

A group of officials discussed for a while, and Pan Shien, the right judge of the Great Food King's Mansion, tried to speak:

"Wang, Liu Changshi, and his subordinates think that textile and garment factories do not need to be placed in the territory of Dashiguo.

"According to the king's long-term plan, the defense of Quicksand City only retains the oil extraction industry, and the petrochemical industry is placed on the coast of the Great Food Sea.

"As for the textile and garment industry chain, my subordinates think that it should not be placed in Quicksand City, or even in the local food country.

"You can put it on the west coast of the Great Qin Sea or Crete, and recruit Tessie workers to do it.

"Solving the problem of manpower shortage from Daming can also reduce production costs."

When Xu Minghui heard this suggestion, he subconsciously followed and said:

"If you want to reduce costs, it is better to put the factory directly in the east of Mozhou and use the Mozhou slaves to work.

"Anyway, a place as big as the eastern part of Mozhou now belongs to our Great Food Country.

"Especially a large piece in the middle, which directly belongs to the king's private property."

Zhu Jingyuan asked a little uncertainly:

"The Tessie workers are fine, the words of the Moren slaves...... Can you do the work of a textile and garment factory? ”

Xu Minghui and Liu Zhixin, as well as other ministers and craftsmen, were a little hesitant to give a definite answer to this question.

They really don't believe much in the abilities of the Moren, including Xu Minghui himself, who made this suggestion.

After hesitating for a few seconds, Pan Shien tried to say:

"If the Mo people can't do it, why don't you introduce the Tianzhu people to the East Mo Continent?"

This suggestion was quickly endorsed by the courtiers and craftsmen around him.

In the eyes of the Ming people in this world, the Tianzhu people belong to the Hu people, and their status is higher than that of Xiyi in many cases.

Let's try it soon, everyone. 】

Because the Ming people felt that the Tianzhu people were easier to manage than the Xiyi people.

Zhu Jingyuan was suddenly a little speechless.

If the British went to Mozhou to transport Tianzhu people, and the Ming Dynasty also transported Tianzhu people to Mozhou, Tianzhu would not be left behind.

Will Mozhou become a large Tianzhu?

But if you think about it from another angle, the large Tianzhu seems to be better than the "Mo" continent.
