Hemp fabric is known to be the premier natural antibacterial fabric often referred to as the “king of the natural fibers,” and the “second skin.” It was first cultivated in Ancient China over 5,000 years ago. It has now grown globally, led by China, India, Russia, Turkey, Hungary, Romania, and Poland.
Today’s hemp contains less than 0.3% THC, which is below global safety standards, which means hemp is non-toxic and safe for daily wear. Hemp is naturally antibacterial, breathable, and eco-friendly and is the future of functional fabrics.
Research shows that hemp material has up to a 99% antibacterial efficacy to against the bacteria Staphylococcus aureus and E. coli, as well as Candida albicans. Additionally, it demonstrates significant antimicrobial properties even after multiple laundry cycles, allowing for extended wearing times with less microbe growth in medical and hygiene material.
Cotton blended with hemp has been tested and has better performance than pure cotton material, a 55:45% cotton-hemp blend tested to inhibit up to 99% of Staphylococcus aureus vs pure cotton.
Hemp is natural, fights bacteria and odours, keeping you fresh and irritation-free.
Hemp fabric’s unique structure and natural chemistry make it the textile with the best antibacterial effect offering unmatched protection, comfort, and sustainability for today’s health-conscious and eco-aware world
