What Are Recycled Yarns?

When we talk about recycled yarn, we mean the pre-consumer recycled yarns made from recycled fibers or from recycled woven fabrics. Recycled fibers or fabrics will be cut into graininess, then after a series of treatments and melt extrusion, they will get re-spun and plied into yarns.

Why We Use Recycled Yarns To Make Waterproof Socks?

Sustainability is of paramount importance to us. With RANDY SUN waterproof socks made of recycled yarns, you can enjoy outdoor activities, responsibly. Recycled yarns products that place less burden on nature, the environment, and all who live in them. By using environmentally friendly recycled yarns waterproof socks, you can have a positive impact on the planet.

The recycled yarns in our assortment are made from responsible materials that, throughout their production and manufacturing processes, have as little impact as possible on the planet and the humans and animals involved. As part of this responsible production process, attention is paid to compliance with social standards. And extra consideration is given to creating a safe and hygienic working environment for every employee involved in the production process.

Properties Of Recycled Yarns

Recycled yarns share the same properties as the textile fibers they are created from. But for the most part recycled yarns are all going to be quite strong and durable. If the recycled yarns are fiber-based (and are spun and plied into traditional yarns), they act just like their non-recycled counterparts.

Reduce Packaging Waste

Packaging accounts for nearly a third of municipal solid waste in the United States, according to the U.S. EPA. Some packaging items often end up as litter where they pollute marine environments, and persist in the environment and in living organisms for much longer than they are in use. We are trying to use very simple packaging of this recycled yarn waterproof socks to reduce waste and decrease the chance of such damage.

Moisture Wicking Coolmax & Anti-Blisters

COOLMAX is a high-performance moisture-wicking polyester fiber developed in 1986 by Invita (which was then called DuPont). Its unique 4-channel fiber design provides enhanced moisture management and highly breathable properties.

This fiber inherently encourages the passage of moisture & heat away from the skin to the surface of the socks for rapid evaporation, which prevents blisters and uncomfortable chafing.
