The craftsmen further improve the engineering technology.

Later, the cotton textile center moved to Jiangnan. Shandong was suppressed and restricted by climatic conditions, so Jiangnan craftsmen continued to improve in production activities.

Every improvement doubles the textile efficiency!

It can even increase several times at once.

Combined with a steam engine?

Sorry, the existing textile technology is not suitable for the use of steam engines.

Not even worthy of using hydraulic machinery.

Water-powered linen spinning machines have gradually become popular, causing the price of linen to continue to fall. The linen that was once rare for the Koryo people was sold by the Ming Dynasty merchants at a low price. Now that Goryeo is a Korean province, ordinary people there no longer have to go naked.

However, cotton fibers are too short, and water-spun cotton yarn is easy to break, let alone cotton yarn spun with a steam engine.

The first is to break through the technical difficulties in spinning, and the second is to cultivate higher-quality long-staple cotton.

Zhu Guoxiang said to the owner of Hu's workshop: "You merchants who are spinning and weaving, can you offer a reward to the craftsmen to continue to improve. The "Da Ming Law·Gong Law" has promulgated a patent law. Once improvements are made, the court will protect your interests.

"

"Always trying to improve." The owner of Hu's factory was actually complaining in his heart.

Patents related to cotton textiles have been in litigation for more than ten years. Although the craftsmen also made some money, they were exhausted mentally and physically by the lawsuits and even received physical threats.

In the end, the craftsmen sold their patents to big businessmen one after another, and the big businessmen with the financial advantage took their time to litigate the case.
