What is "Hemp" - Definition & Explanation

A coarse fiber that comes from the hemp (cannabis) plant. Though used mostly for rope and cord, the most refined fibers are also used for woven textiles
A light-coloured, strong bast fibre obtained from the hemp plant Cannabis sativa.
Hemp is a bast fiber that was probably used first in Asia. The fiber is dark tan or brown and is difficult to bleach, but it can be dyed bright and dark colorrs. The hemp fibers vary widely in length, depending upon their ultimate use. Industrial fibers may be several inches long, while fibers used for domestic textiles are about 3/4 inch to 1 inch (1.9 to 2.54 cm) long. The elongation (1 to 6 percent) is low and its elasticity poor. The thermal reactions of hemp and the effect of sunlight are the same as for cotton. Hemp is moth resistant, but it is not impervious to mildew. Coarse hemp fibers and yarns are woven into cordage, rope, sacking and heavy-duty tarpaulins. In Italy, fine hemp fibers are used for interior design and apparel fabrics. Hemp is a very durable fiber that holds its shape. It grows without the use of pesticides, herbicides or chemical fertilizers and can withstand harsh growing seasons. Hemp cultivation does not exhaust, but rather continuously fertilizes the soil by shedding its leaves throughout its growing period. In this way, it actually returns nutrients to the soil, helping to reduce the energy demand on the Earth. It is also naturally UV resistant and dries quickly.
A coarse, durable bast fiber obtained from the inner bark of the hemp plant. Used primarily in twines and cordages, and most recently apparel.
The main uses of hemp fibre are rope, sacking, carpet, nets and webbing. Hemp is also being used in increasing quantities in paper manufacturing. The cellulose content is about 70%.
Hemp is currently being used by designers in clothing. When thinking of hemp, the illegal plant, marijuana comes to mind. No, hemp fabric does not contain the narcotic chemical that, when smoked produces the "high" that smoking marijuana produces. Marijuana is from the dried flowers and leaves of the Cannabis Sativa plant. Hemp fabric is made from the stems of the plant. The stems are processed to dissolve the gum or pectin and separate the fibers which are then processed again and woven into yarns and fabric. The finest hemp for fabric is produced in Italy. Hemp fabric is like linen in both hand and appearance. Hemp fabric withstands water better than any other textile product. It wrinkles easily and should not be creased excessively to avoid wear and breakage of the fibers.
Hemp is a course fiber made from the inner bark of the hemp plant. It is becoming increasingly popular for use in diapers because of its durability, absorbency and natural anti-microbial properties.
Textiles A plant fibre, is naturally mould and rot resistant. It is very strong and has good shape retention. Over time it softens and develops a rich silky patina. It has excellent thermal properties and can filter up to 95% of UV light.
