In the course of putting on a soft and warm sweater, have you ever thought about the way it was produced? The making of yarn is a special process, and one of the most important parts of that process is something called the "core." The core is the heart of yarn, so to speak. It needs a good core, very important, so the yarn does not fall apart when you band it. A poor core means the yarn can lose strength and break.
Eheng knows a thing or two about building solid and steady yarn cores. A core is an inner shaft of a strand with little fibers wrapped around its outside to hold them together. You can consider it as a backbone in our bodies, just as our spine helps us to stand and to move the core is very significant for the yarn to stay together. We utilize specialized spinning methods at Eheng, which allow our cords to have a high tensile strength and consistency, ensuring the quality of our yarn.
The spinning methods of Eheng are important for pesticide-free and strong and tough yarn. Spinning fibers around a core also makes the yarn more durable. "Meaning the yarn is sturdy - it can take a lot of use before it gets ruined." We can also add additional materials on top of the core such as nylon to increase the strength of the yarn. Nylon added to the yarn also makes it much more durable, allowing for a range of uses.
Eheng revolutionized the spinning world by producing what is known as core spinning yarn. This type of yarn is strong enough to be used for heavy-duty items, such as parachute cords and seatbelts. They need to be really tough to keep people safe and our core spinning yarn is ideal for that. Core spinning has also enabled us to blend various weave types that are soft and strong at the same time. That way, you can enjoy the softness of the yarn, and then know that it is incredibly durable as well. With Eheng's core spinning yarn, you can have your cake and eath it too!
One of the biggest advantages of core-spinning is that it allows us to make an even, consistent yarn. It means that all the pieces of yarn are consistent in thickness and quality. Yarn is easier to work with when it is even whether knitting, crocheting, or weaving. Spin blending is also a possibility between lighter cotton and wool fluffy material, to create soft and strong yarn blends. These yarn blends offer people plenty of selection for their various projects.
We at Eheng take great pride in being a company of core-spinning experts. We are artists with the knowledge of building cores that are strong and stable regardless of the types of fibers used.
