Much has been written about the sustainability and advantages of hemp as a crop and its many uses. Hemp fabric has a lot of advantages over other vegetable and synthetic fabrics. Here are a few:
-Hemp is the strongest vegetable fiber on the planet with up to three times the tensile strength of cotton. Hemp fabric is also very tear resistant. This is why historically hemp was used to make rope, sails, and flags.
-Even after processing, hemp will retain a large amount of its natural cannabinol compounds. These render it highly mildew-resistant, a major advantage over cotton and other natural materials.
-Hemp fiber is filled with minute air pockets that make it both thermally and acoustically insulating. This “spongy” quality also makes help very breathable.
-Hemp fabric can shield more than 95% of the sun’s harmful UV rays.
-With its high silica content, hemp is resistant to the damaging effects of insects and other pests.
-Like cotton and several other vegetable fibers, hemp has high heat-resistance, an advantage over synthetics.
There are those who claim that hemp is a highly evolved plant species. It has the ability to grow well in a variety of climates and soil types. Naturally pest resistant, it grows very tightly spaced and will out-compete any weeds, eliminating any need for herbicides. For these reasons, hemp has never been genetically modified (and hopefully never will).
