Hemp fiber

Hemp fiber - a raw material for the manufacture of hemp, which is then spun into yarn and thread and Suchat rope. In raw form hemp fiber can be used as raw material for paper and cardboard, as well as woven mats.
Bast layer of hemp stalk contains an average of about 20-25% of the fiber from the male plants and about 12-20% for women. For a variety of industrial hemp varieties sown, this figure reaches 35-40%. average fiber length of about 1.8 m to 2.5 m times.

Good moisture supply during the growing period, the most important for the formation of fibers in the stem. The lack of moisture in the fibers are unconsolidated stems with large openings, which indicates poor quality.
The formation of the primary fibers (of length bast cells from 8 to 55 mm) occurs in a period of vegetative growth and the hemp fully completed when the plant ceases to increase in height. The period of full flowering to full ripening recycled fiber produced in the stems (with a bast cells to 4 mm). It is much less durable and is usually removed during carding.

In hemp fibers reach maximum strength by the end of full bloom, at materki and monoecious hemp in the period of full maturity of seeds. In the earlier period, cleaning fiber quality is still poor, and instead of hemp can be obtained tow. The best fibers are obtained from plants in crops close drill, and high slabovetvyaschihsya with a stem diameter of 5-8 mm.

Bundles of fibers in hemp stalk covered with a thin rind, glued together with vegetable proteins and fit snugly to the wood parts. Distinguish them from the stem can be either by decortication, or by retting, drying and softening, or chemical means (cooking in ammonium phosphate solution).

The porosity of hemp fabric allows better absorb moisture and, therefore, loss of color during washing minimal. It also allows the body to "breathe" during the intense heat, keeping cool.
Attention should be paid to the positive psychological and physical impact of the clothes, which is associated with a beneficial effect on the nervous system by contacting the exocrine glands with a cloth.
