Linen rope is a wickerwork. It is obtained by combining several threads into strands, which are then twisted into a rope. It is made from coarse flax fiber and is used for packaging, industrial, construction and transport purposes. Products of this kind have been popular for centuries due to their low cost, combined with high strength, a sufficient coefficient of friction, slight extensibility and low electrification. Recently, the material began to be appreciated for its interesting decorative properties.
Due to the absence of accumulation of static electricity, the linen cord is successfully used for work with flammable or explosive goods. When burning, this product does not emit harmful components, which allows it to be used in the creation of life-saving equipment. In addition, the cord is quite light, which increases the convenience of its use. Products of this kind were especially popular with sailors of past centuries, until they were replaced by marine chains for anchors and synthetic materials for rigging ships.
Linen rope likea product based on natural raw materials is subject to the influence of the external environment. But this does not prevent it from being used in construction for decorating the seams of log cabins (instead of tow) or decorating the interior elements of the premises. To increase the service life in this case, such an environmentally friendly product as linseed oil is used, which is impregnated with products. Ropes are sometimes used by designers to create crafts and decorations. For example, thin cords can be seen as the basis for jewelry made from natural materials. Thick ones are suitable for braiding.
The production of ropes is regulated by several state standards, among which No. 1765-89 just refers to linen rope products. This document states that cords can be produced with a diameter of 6-14 millimeters and consist of 3-4 strands, each of which includes 9-12 cables (a cable is a linen strand impregnated with anti-corrosion and antiseptic compounds that provide improved biostability and prolong the term product operation). Ropes made from natural materials are strong enough and withstand loads from 330 to 1050 kg, depending on the brand of goods.
Linen rope is produced on the basis of GOST No. 1868-88. For its manufacture, only short fibers (up to number three) are taken. When producing such products, they are guided by the same principle as when making ropes - the yarn is twisted into strands, which are then twisted into ropes. In this case, the twisting of yarn and strands is usually done in directions opposite to each other.friend.
State standards indicate that pure linen raw materials are not used today. Instead, hemp is added to flax for production, which makes it possible to obtain products with a diameter of 6.5-24 mm, which can withstand loads up to 1400 daN. The finished product should not contain free alkalis, acids, copper s alts, which will allow flax ropes to be recognized as environmentally friendly products. Unfortunately, both rope and linen cord are products with a fairly short shelf life. For example, according to GOST, the guaranteed shelf life for them is one year from the date of manufacture.
