Recycled yarn - Recyclable cotton yarn
Keywords: cotton recycling, blends with water soluble fibers, recycling yarn
With the invented yarn, a certain proportion of synthetic fibers made from polyvinyl alcohol (PVA) is added to the natural cotton fibers during spinning, which can be dissolved again with hot water during recycling. This means that the yarn loses strength on the textile surface and can then be mechanically disintegrated more gently. The recovered cotton fibers are shortened to a lesser extent by this.
- Cotton recycling
- Promotion of sustainability
- Environmental friendly
Only a small percentage of cotton is currently recycled. The invention now makes it possible to spin cotton yarns that can be opened up considerably better into individual fibers. As a result, higher quality products can be produced from expensive raw materials such as cotton. An application in the textile and jeans manufacturing industries, which are concerning themselves with the topic of sustainability and want to get involved there, is conceivable because very large quantities of cotton that is dyed the same are used here.
A patent has been filed for the invention. A prototype is to be built and tested as part of a project. On behalf of Hochschule Niederrhein University of Applied Sciences, PROvendis offers interested companies licenses for the invention and patent application.
An invention of HS Niederrhein.
