Introducing GCLO, a global leader in eco-friendly functional polymers and products.

After conducting basic R&D of functional polymers and eco-friendly fibers since 2002, G.CLO Inc. was established in 2011 with the goal of becoming a more professional ‘eco-friendly functional polymer R&D best company’.

After continuous R&D with registration of numerous domestic and global patents and acquisition of various certificates, in 2016, we became a partner with the PD Group, which owns Courtaulds textile in the UK, which has led the textile industry for more than 200 years.


In 2019, we launched the Ceravida® technology brand with the completion of Junlite, a human-friendly and nature-friendly bioceramic material, and started to achieve innovation with eco-friendly functional polymer material technology.


As a result of long-term R&D efforts, in 2020, along with the FDA medical device registration of a multifunctional function yarn for HEAT, COOL, and RECOVER, antibacterial agents using pure natural substances were completed.


G.CLO, based on the achievements of over 20 years of research and development, has applied innovative and creative Ceravida® technology to our daily products starting in 2021, for a healthier and more comfortable life and our sustainable environment. We will become a leading company in ‘Eco-friendly functional technologies and products through creative technological innovation’.

Founded in 1794 by George Courtaulds and his cousin Peter Taylor in Pebmarsh, North Essex, as a silk, crepe and textile business.


1794-1904 Courtaulds played a very important role in the history of British textile manufacturing.


From 1904 to 1968, he pioneered the manufacture of rayon through the viscose process, leading the technological development in the textile industry.


In 1904, Coventry opened the first plant to produce rayon and weaved into fabrics at the Halstead Mill in Essex, becoming the world’s first man-made fiber producer. The subsequent expansion into the acetate fiber, cotton and hosiery industries controlled around 30% of UK cotton spinning capacity and 35% of warp knitting production.
