What Kind Of Wool Called High Quality

what kind of wool is called high quality? Wool is based on wool as the main raw material of textile fabrics, so the quality of wool is directly related to the quality of the woven products. So what kind of wool is good wool?

Wool is an important textile raw material, and goat wool in addition to angora goat wool (I. e., mohair) are fine hair is too short, coarse hair is too hard and is not conducive to spinning, so the wool used for textile is basically sheep wool.

Goat and sheep wool
The preponderance of world wool production is in the southern hemisphere.
Oceania's raw wool production accounts for about 40% of the world's total raw wool. Australia mainly produces fine wool and New Zealand mainly produces semi-fine wool. Australia, New Zealand, the Soviet Union and China are the major producers of wool, accounting for about 60% of the world's total wool production.

Among them, the most famous wool for wool knitted fabrics is the wool produced by Merino fine wool sheep. All the world's fine wool breeds are produced from merino sheep or sheep of predominantly merino descent.

The original sheep breeds in China belong to Mongolian sheep, Tibetan sheep, Kazakh sheep and Altai sheep. The wool produced is of rough quality and belongs to mixed wool. As a raw material for woolen fabrics for clothing, it is of poor quality and is mainly used for carpet wool. At present, China has bred Xinjiang fine wool sheep and northeast fine wool sheep through the introduction of foreign varieties, which has improved the quality of wool, but there is still a certain gap in the Merino wool produced in Australia.

Identify the quality of raw hair
One is to look at the color, high-quality Australian merino wool is white, European wool is white yellow, domestic wool is gray white. If the wool is snow-white, it is likely that too much decontamination treatment has been carried out to cover up the poor quality of the wool, which will damage the surface protein of the wool and shorten the physical strength of the wool.

The second is to look at the length and curl of the wool. The high-quality fine wool fibers are fine and uniform, with an average diameter of not more than 25 microns, a length of 5-10cm, soft and curved, good elasticity, and soft luster.

The third is to smell, wool after cleaning, carbonization, shrink-proof and other processes will not leave any odor, including sheep smell, only a light wool unique taste.

The fourth is to measure the rebound, through extrusion and other ways to detect its compression resilience, and through the control of high-quality wool to test the same weight of wool bulkiness to visually identify the resilience of wool.
