What are the advantages of using hemp for fabric?
Hemp has been increasingly used in the textile industry with limited widespread use likely linked to other uses for hemp outside of clothing, namely recreational drug use. The texture of hemp varies based on the environment in which it is grown and can range from coarse to soft. One of the advantages of using Hemp fabric is that it is naturally antimicrobial. The potential for hemp to be naturally sun protective is based on the stitch density of the fabric. Studies evaluating the natural UPF of 100% hemp vary from 5.8 to 50+ depending on the stitch density. There are natural pigments within the hemp textile that add to its ability to protect from the sun.
Would you consider hemp to be an environmentally friendly fabric?
Hemp is considered eco-friendly given the small amounts of water needed, its natural tendency to resist pests requiring little pesticide use, and little fertilizer use.
If given a choice, which would you prefer: hemp or cotton?
In terms of texture and feel, cotton most often has a much better feel. In terms of cost, hemp is more expensive to work with.
From an eco-friendly perspective, studies have shown that it can take over 250 gallons of water needed to grow the cotton required to produce just one cotton T-shirt. (CCGGA, 2019), The Guardian reported that in 2013 India’s cotton exports would have been enough to supply 85% of their 1.24 billion people with 100 liters of water every day for a year. This was at a time when 100 million of their people did not have access to safe water. (Guardian, 2015) Organic cotton has gained in popularity owing to the fact that it is grown without the use of toxic synthetic pesticides and fertilizers. However, to be labeled as organic, the only criteria to meet is to utilize USDA-certified organic crops in production. The word "organic" can still be ascribed to cotton that utilizes certified organic crops even if it has been chemically modified with finishes or dyes. (USDA, 2019)
I had attempted to integrate hemp into our collection of sun-protective textiles that do not use UV chemical finishes in the past. From a manufacturing point of view, hemp is a coarser and stronger fiber and more expensive to work with. We will continue to determine if we can increase the stitch density to gain natural sun protection while still creating a fashionable yet affordable look and a textile that feels soft against the skin. This is very much a work in progress, however.
