The definition and classification of hemp are defined in Xinhua dictionary. There are many species of herbaceous plants, such as hemp, ramie, flax and Aboriginal hemp.

The bark fiber is also called "hemp", which can make rope and weaving cloth.

The definition of cannabis is the annual herb of the genus Sancho, with the English name hemp and Latin name CannabisSalival.

Also known as hemp, cold hemp, linen, hemp and so on, the English hemp, the variety of about 150, generally can be divided into fiber, oil and medicinal marijuana three categories.

Hemp fiber is the main characteristic of cannabis, which has good natural growth ability and easy planting.

In particular, the hemp varieties in Northeast China are among the best in the world.

Hemp fiber is the most natural and natural degradable fiber in natural fibers. It has been used for 5000 years in China.

Hemp fiber is superior to cotton, flax and ramie, and is the best textile material.

This may be related to the need for confidentiality in the early application of hemp fibres in the military field.

But with the further development of civilian products, there is still considerable room for further research and development of more standards. We hope that relevant departments and related engineering and technical personnel will take active action to make positive efforts to improve the standard of hemp fiber and its products as soon as possible and speed up product development.

Its excellent characteristics are as follows:

Bacteriostasis and deodorization -- hemp textiles retain and adsorb cannabinol compounds that kill and inhibit bacteria. Therefore, they have the ability of anti fungus and deodorant. After testing, the antibacterial and deodorant properties of pure cotton fabrics are 0%, flax 70% and hemp fabrics 90%.

Moisture absorption and perspiration - the hemp fiber center has a slender cavity connected with many cracks and small holes distributed on the surface of the fiber. The excellent capillary effect makes the hemp fiber hygroscopic, perspiration and air permeability exceptionally good, making people feel comfortable and cool.

Heat resistant sound insulation - hemp fiber has good heat resistance and sound insulation.

It can withstand the test of high temperature above 370 degrees (3).

Light resistant anticorrosion - hemp fiber has good fastness to sunlight, good corrosion resistance to seawater and durable.

The antistatic property is high. Hemp fiber has stable molecular structure, good orientation of molecular alignment, and extremely low electrostatic generation capacity.

Hemp textiles can avoid static electricity accumulation and will not pilling and absorbing dust due to friction.

Anti ultraviolet effect is good. Hemp fiber cross section shows irregular triangles, polygons and so on. Its molecular structure is multi prismatic, loose and spiral, so it has no itchy feeling, and has good dissipation effect on ultraviolet and sound waves.

The mechanical and physical properties are strong. Hemp fiber has good mechanical and physical properties, its fineness and intensity, and the number of domestic and international standards retrieved from China and abroad, the number and coverage of cannabis standards in China are more and more complete.

But generally speaking, the testing methods and technical standards of hemp fiber are not sound enough, especially in printing, dyeing, knitting, dyed fabrics and so on.

But fiber breaking strength is better than flax, lower than ramie, spinning according to linen process, theoretically, hemp fiber can be spun more than linen and flax.

Therefore, if we further improve the fineness of hemp fiber, we will make hemp textiles become flax.

A strong competitor.
