PROPERTIES OF HEMP

PROPERTIES

For thousands of years hemp was traditionally used as an industrial fiber. Sailors relied upon hemp cordage for strength to hold their ships and sails, and the coarseness of the fiber made hemp useful for canvas, sailcloth, sacks, rope, and paper.

While hemp fiber was the first choice for industry, the coarseness of the fiber restricted hemp from apparel and most home uses. Hemp needed to be softened. Traditional methods to soften vegetable fibers used acids to remove lignin, a type of natural glue found in many plant fibers. While this method to remove lignin worked well with cotton or flax, it weakened the fibers of hemp and left them too unstable for use. Hemp therefore remained as an industrial fabric.

In the mid 1980's, researchers developed an enzymatic process to successfully remove lignin from the hemp fiber without compromising its strength. For the first time in history, de-gummed hemp fiber could be spun alone or with other fibers to produce textiles for apparel. This technological breakthrough has catapulted hemp to the forefront of modern textile design and fashion. Given hemp's superiority to other fibers, the benefits of this breakthrough are enormous.

Superior Properties
Hemp fiber is one of the strongest and most durable of all natural textile fibers. Products made from hemp will outlast their competition by many years. Not only is hemp strong, but it also holds its shape, stretching less than any other natural fiber. This prevents hemp garments from stretching out or becoming distorted with use. Hemp may be known for its durability, but its comfort and style are second to none. The more hemp is used, the softer it gets. Hemp doesn't wear out, it wears in. Hemp is also naturally resistant to mold and ultraviolet light.

Due to the porous nature of the fiber, hemp is more water absorbent, and will dye and retain its color better than any fabric including cotton. This porous nature allows hemp to "breathe," so that it is cool in warm weather. Furthermore, air which is trapped in the fibers is warmed by the body, making hemp garments naturally warm in cooler weather.

Environmental Advantages
Hemp is an extremely fast growing crop, producing more fiber yield per acre than any other source. Hemp can produce 250% more fiber than cotton and 600% more fiber than flax using the same amount of land. The amount of land needed for obtaining equal yields of fiber place hemp at an advantage over other fibers.

Hemp grows best in warm tropical zones or in moderately cool, temperate climates, such as the United States. Hemp leaves the soil in excellent condition for any succeeding crop, especially when weeds may otherwise be troublesome. Where the ground permits, hemp's strong roots descend for three feet or more. The roots anchor and protect the soil from runoff, building and preserving topsoil and subsoil structures similar to those of forests. Moreover, hemp does not exhaust the soil. Hemp plants shed their leaves all through the growing season, adding rich organic matter to the topsoil and helping it retain moisture. Farmers have reported excellent hemp growth on land that had been cultivated steadily for nearly 100 years.

Hemp Today
As a fabric, hemp provides all the warmth and softness of a natural textile but with a superior durability seldom found in other materials. Hemp is extremely versatile and can be used for countless products such as apparel, accessories, shoes, furniture, and home furnishings. Apparel made from hemp incorporates all the beneficial qualities and will likely last longer and withstand harsh conditions. Hemp blended with other fibers easily incorporates the desirable qualities of both textiles. The soft elasticity of cotton or the smooth texture of silk combined with the natural strength of hemp creates a whole new genre of fashion design. 

The possibilities for hemp fabrics are immense. It is likely that they will eventually supersede cotton, linen, and polyester in numerous areas. With so many uses and the potential to be produced cheaply, hemp textiles are the wave of the future!
