What Is CiCLO® Technology?
CiCLO® is a revolutionary additive built directly into the yarn fibre during production.
It allows synthetic fibres to behave more like natural materials, should they end up in landfill or the ocean, helping reduce the time they persist in our environment.
CiCLO® doesn’t change:
your knit or crochet experience
cost to make
convenient care
the lifetime of your makes
It only activates in specific environments like landfill where it helps to reduce the long-term persistence of the synthetic fibres in your yarn blend.
How Does CiCLO® Work?
Microbes, which exist naturally in places like soil and seawater, digest and break down natural fibres which enter those environments. Microbes cannot digest synthetic fibres like polyester so ignore them.
Award-winning CiCLO® technology makes CiCLO® recycled polyester both appealing to and digestible by microbes, so instead of sitting unchanged for decades, they will behave like natural fibres in the right conditions.
Materials Matter for Makers
As knitters and crocheters, we invest time, skill and love into what we make. Synthetic yarns have always offered affordability, vibrancy and convenient care. Now with CiCLO® technology we can offera solution to the challenge they present to our environment too.
You Can Make A Difference
Sirdar Loveful Bio Blend is the first hand knitting yarn to feature award-winning CiCLO® technology.
It represents a step forward not just for Sirdar, but for the future of affordable, sustainable knit and crochet. Because where we lead, others follow.
And because small changes, multiplied by thousands of makes, can create real impact.
