Textiles, Part 10: "Types of Spun Yarn ~Ring-Spun Yarn~"

Hello everyone!

This time, building on our previous discussion of "Spinning," we'll introduce the different types of spun yarn.

First, the stage in the spinning process where yarn types are categorized is "finishing."

The type of spinning machine determines the type of yarn produced.

This time, we'll focus on the most common of the three main types: "ring-spun yarn."

"Ring-Spun Yarn"

Ring-spinning machines began to spread in Japan around 1890. Before that, yarn was produced using spinning machines called "mule spinning machines."

During this period, Japan was in the midst of the Industrial Revolution. The textile industry, one of the industries supporting Japan, was steadily developing, and the highly efficient ring-spinning machines were introduced one after another, becoming the mainstream.

To briefly explain the mechanism, the roving is stretched by two rollers with different rotation speeds, and then twisted as it passes through parts called a "ring" and a "traveler" before being wound onto a bobbin.

You can see how the roving is supplied from above, and how the twisted yarn is wound onto the bobbin.

A key feature is that there are no untwisted sections; the entire yarn is uniformly twisted.

Because it produces fluff, the resulting fabric has a soft feel.

Summary of today's lesson:

The type of spinning machine determines the type of spun yarn.

Currently, the most common yarn is "ring-spun yarn," produced using a ring spinning machine.

Before that, mule spinning machines were the mainstream.

The yarn is twisted using a ring and traveler.

The entire yarn is uniformly twisted.

Because it produces fluff, the resulting fabric has a soft feel.

We will introduce the remaining two types of spun yarn in the next lesson.

Thank you for reading to the end.
