Fortunately, it didn't take long to wait, and the experimental time had already met the set requirements, so Director Cheng personally took out the experimental samples for confirmation.

"Brother Cheng, has this experiment failed? There are so many pores on it. If you use it to make a raincoat, it will definitely leak."

Yuchi Hui, who was originally looking forward to this experiment, showed a disappointed expression on his face as soon as he saw the sample in Cheng Chucai's hand.

His expectation just now disappeared without a trace.

"Brother Yuchi, it is definitely not suitable to make raincoats, but whether it has special uses in other occasions needs further confirmation."

After confirming the difference between the results of this experiment and the previous one, Cheng Chucai kept thinking about the use of this rubber product.

"The rubber has become like this after processing, and it looks like it's like there's only ash left after the wood burns."

Yuchi Hui couldn't help but say something in a depressed mood.

There was no way. In his opinion, the pair of rubber products in front of him were really a pile of waste, and it was obvious that the refining failed.

"Brother Yuchi, look at this rubber product. Although the shape has changed a lot, its originally dense appearance has been completely changed, and it seems that it is not very suitable to make seals.

But don’t you think this thing has become very fluffy, and you press your hands, step on your feet, or sit on your butt, it seems to be able to bounce back like a spring?

If we use this rubber product to cooperate with sofa manufacturers in the Workshop City, can we make sofas with better comfort?

I remember that the luxury carriages produced by Mercedes-Benz four-wheeled carriage workshops all use whale leather sofas, and it seems that they are not very satisfied with the filling inside."

Cheng Chucai suddenly thought of the sofa in his luxurious carriage, although at the beginning it felt much better than the hard wooden boards.

But I always feel a little unsatisfied.

If your rubber product is combined with the spring, the effect seems to be better.

"Is this just something?"

After hearing what Cheng Chu said, Yuchi Hui took the sample from his hand and experienced it carefully.

Not to mention, without reminding, this thing looks like garbage.

However, after Cheng Chu reminded him, Yuchi Hui felt that he had made the newly created sample and felt that it was good.

Although it is a rubber product, its elasticity is no less than that of a spring.

The most important thing is that after fluffy, the volume of rubber has increased several times compared to before, and the weight per unit volume has decreased significantly.

If this expansion ratio can be further controlled, using this kind of primitive as the filling of the sofa will be much more comfortable than the current ones.

"Yes, this is this thing! I think the use of rubber processing products after expansion is actually worth looking forward to.

It may even become a brand new material and open up new areas of application for many workshops."

The more Cheng Chucai said, the more confident he felt.

The industry of the Tang Dynasty is now in its infancy, and all kinds of things are still unripe.

Many parts are made simply and roughly using wood or steel.

But not all parts are suitable for making steel or wood.

"From the current situation, when special materials are added, the rubber processing products will expand.

However, how to control this expansion ratio may be related to the amount of addition of this material, so we need to further confirm.

For sofas, too fluffy or too tight materials are not the most suitable.

We need to work with the sofa workshop to find the most suitable proportion.”

Yuchi Hui thought of the use of the sofa in the four-wheeled carriage workshop and many nobles' homes, and he felt more anticipated.

"Well, it is indeed necessary to work with the sofa workshop. After all, we are not the most professional in this regard."

"Brother Cheng, the sofa can be used as a filling material.

I suddenly thought that if our beds also use this material as mattresses, would there be a big market?”

Yuchi Hui's thinking is becoming more and more divergent.

During this period, in order to make the Yuchi Cheng rubber workshop run smoothly, he kept thinking about various ideas.

Every day, we will also gather craftsmen to brainstorm the new uses of rubber.

Now that he was prompted by Cheng Chucai, he immediately thought of more other application scenarios.

"Use our materials to make mattresses? Sofas are OK, but there seems to be no reason for mattresses to be not."

Cheng Chucai's eyes also became much brighter.

Nowadays, wealthy families may use quilts or animal fur in the mattresses of various households in the Tang Dynasty.

However, many ordinary families only have one straw mat, and they directly pounce the straw mat on the wooden board.

Or put a layer of straw on the straw mat, and the warmth effect is also smooth.

But the comfort level of these things is definitely very limited.

Cheng Chucai imagined the feel of the whale leather sofa, and then imagined that his mattresses had all turned into that look, and he became more and more excited.

"Brother Yuchi, do you think we should just build another workshop specifically for the production of mattresses and sofas?

This new filling is only mastered by our workshop, and no one else knows about it.

Even if they want to study, there will be no results in a short period of time.”

Although Cheng Chu is not a greedy person.

But he still doesn't want to give up on the benefits that can be touched by such deep hands.

"If you build a workshop separately, you need to report to your home."

Yuchi Hui hesitated for a moment.

He is just Yuchi Gong's nephew, not his son.

Many times, if he can do it without discussing it with his family, he hopes to do it himself as much as possible.

"It doesn't matter! This new mattress is an epoch-making product. We report this plan to our home, which is good news.

Even if the family doesn’t want us to do so much, they won’t blame us for this.”

"Okay, since that's the case, then we'll go back and discuss as soon as possible.

But before this, we need to confirm how to make the best rubber processed product for sofas and mattresses.”

Cheng Chucai's words made a lot of sense. Yuchi Hui thought about it but couldn't find a reason to refute it.

"The name of rubber processing is really difficult to describe, and others suddenly know that this thing is made of rubber.

Disadvantage our technology from confidentiality.

In my opinion, let’s call this thing a foam.”

The more Cheng Chucai said, the more he felt, and he was full of energy.

"Foam? There are many holes on it, just like bubbles appearing during production.

The overall feeling is that it has a little similarity to cotton, and it is really appropriate to describe it as foam."

Soon, among the words of Yuchi Hui and Cheng Chucai, there was another thing called foam in the Tang Dynasty.

...

Everything is difficult at the beginning.

Once you have a clue, many things will be easier to do.

This is especially true in scientific research.

I know what materials will cause rubber foam to become foam, and the rest is nothing more than doing a few more tests.

Soon, Cheng Chu found a relatively suitable foaming ratio.

Next, they bought two sofas from outside in a simple and rough manner, then took them apart and replaced the filling with foam.

Then they went home to report the situation.

"This is the sofa produced in our workshop? When did you start making sofas?

It feels good to do."

Although Cheng Yaojin gives people the impression that he is careless, most of the time, he is actually very careful.

He sat on the sofa that Cheng Chucai had returned in various sitting positions and felt it carefully, and he really felt the gap.

"Aye, this sofa was made as a filling that we accidentally discovered during the experiment.

The other parts of the sofa are purchased directly from the market, and the filling inside is now replaced.

It is said that they can quickly make large quantities of this kind of sofa and promote it to the market.

We were squatting at the entrance of the Mercedes-Benz four-wheeled carriage workshop and reported that yesterday, the sofa workshop of Yuchi Cheng transported several sofas from carriages into it.

I guess their luxury carriage will soon start using new products from Yuchicheng sofa workshop.”

Wei Bao listened to his friend's report on the news with a solemn expression.

Although the sofa is not the core part on the carriage, it is the part that people riding in the carriage are most exposed to.
