How do you evaluate the fineness of wool? What is superfine wool

Wool fineness is to determine the quality and use value of wool fibers.

important process characteristics, expressed in microns or mass count of fibers; The smaller the fineness, the higher the count count, and the finer the yarn spun.

The count is a unit of fiber or yarn thickness. It is expressed as the length of the fiber or yarn per unit weight at a nominal moisture regain rate. Due to the different calculation unit systems, it is usually divided into two types: metric and imperial

1. Metric counts. The length (m) of a 1 gram of fiber or yarn at a nominal moisture regain rate. The finer the fiber or yarn, the higher the metric count.

The thickness of hemp fiber and wool yarn, wool chemical fiber pure spinning and blended yarn, as well as silk spinning yarn and ramie yarn is expressed by metric counts. The metric count of strands is expressed by the nominal count of the single yarn that makes up the strands divided by the number of strands.

2. Imperial counts. The length of the yarn in kilograms at a nominal moisture regain rate (cotton yarn is 768 meters per strand). The finer the yarn, the higher the imperial thread count.

Due to the inconvenience of calculation, this representation is now used in fewer countries. The imperial thread number of strands is expressed in a similar way to the metric thread number.

Therefore, wool fineness can be quantified in terms of microns in diameter, or thread count.

The fineness of wool needs to be tested, there are many specifications, the common specification is 56s-80s, you can see the figure for details:

The average fineness of wool reaches 20 microns and the average length reaches centimeters, both of which exceed the international superfine wool standards with an average fineness of 25 microns and an average length of centimeters.

The reporter saw a handful of wool at the Xinjiang Academy of Agricultural and Reclamation Sciences, which was only a micron fine compared with the world's finest wool. This is the superfine wool produced by the Xinjiang Corps themselves. The Xinjiang Academy of Agricultural and Reclamation Sciences sent 5 kilograms of such wool to the Wool and Cashmere Quality Inspection Center of the Ministry of Agriculture for testing, and the conclusion was:

The fineness reaches micron to micron, and the comprehensive quality reaches the world's advanced level.

The number of Australian wool quality is 66 70 (average diameter 20, wool bush length 57 102mm).

The average weight of the adult male sheep after shearing is kilograms, the average amount of shearing is kilograms, and the average length of the wool is centimeters. The fineness is uniform, the wool fineness is microns, that is, 58 64's, there is a significant large bend, the luster is good, and the net wool rate is.

Breed characteristics

Australian Merino sheep are divided into fine-haired, medium-haired and strong types, and each type is divided into horned and hornless. The body shape is approximately rectangular, the body is wide, the back is straight, the hindquarters are muscular, and the legs are short. The ram has 1 3 transverse folds on the neck, and the ewes have longitudinal folds.

Abdominal hair is good. Fine hair type: sturdy physique, medium body, dense and soft, shiny.

Medium hair type: large physique with a lot of hair, broad forebody, good body shape, long and soft hair coat, sufficient oil and sweat, and good luster. Tough:

Large, sturdy physique and good build.

Australia's specially fed merino sheep produce a wool with a diameter of 12 m and 14 m, known in the world as superfine wool. This superfine wool is silky and its fineness is 1 8 of a human hair. Superfine wool is soft and elegant, while ordinary wool is hard, so superfine wool also has a lot of **.

Wool is mainly made up of proteins. The use of wool can be traced back to the Neolithic Age, when it spread from Central Asia to the Mediterranean and other parts of the world, and became the main textile raw material in Asia and Europe. Wool fibres are soft and elastic and can be used to make textiles such as wool, fleece, blankets, felts, etc.

Wool products have the characteristics of plump feel, good warmth, and comfortable wearing. Sheep wool accounts for a significant proportion of textile raw materials. The world's largest production of sheep wool is Australia, the former Soviet Union, New Zealand, Argentina, China, etc.

Sheep wool is divided into five categories according to fineness and length: fine wool, semi-fine wool, long wool, hybrid wool, and coarse wool. Chinese sheep wool varieties include Mongolian wool, Tibetan wool and Kazakh wool. The main factors in assessing the quality of wool are fineness, curl, colour, strength and weed content.

Superfine wool refers to those extremely superfine wools.

In daily life, people wear clothes made of a variety of materials. Among them, wool clothing is also more popular, but the wool fineness used in wool clothing is also different due to different workmanship. For example, there are two types of clothing on the market: superfine wool and wool.

So what is the difference between superfine wool and wool? Is there a wool fineness comparison table to 100?

The differences between superfine wool and wool are as follows.

1. The fineness of wool is different, ultra-fine wool is the wool that is relatively fine in the wool, while ordinary wool is coarse.

2. The comfort is different, the sweater made of superfine wool has good elasticity, the feel is very soft and delicate, and it is more comfortable to wear closely, but ordinary wool trillions will have an itchy feeling after wearing.

3. The taste is different, ultra-fine wool can absorb and lock the odor molecules after sweating, so that the clothes can stay fresh for a long time, while ordinary wool cannot absorb odors.

The wool fineness control is not to 100, but there is a fineness comparison table below 100, and the specific comparison table is as follows.

32 sticks with an average diameter.

36 sticks with an average diameter.

40 sticks with an average diameter.

44 sticks with an average diameter.

46 sticks with an average diameter.

48 sticks with an average diameter.

50 sticks with an average diameter.

56 sticks with an average diameter.

58 sticks with an average rolling diameter.

60 sticks with an average diameter.

64 sticks with an average diameter.

66 sticks with an average diameter.

70 sticks with an average diameter.

The above is the difference between superfine wool and wool, as well as the fineness of wool comparison table, which can also be used for reference.

Difference Between Fine Wool and Cashmere.

1. The scale arrangement of fine wool is tighter and thicker than that of cashmere, and its cashmere shrinkage is greater than that of cashmere.

2. The curl degree of fine wool is greater than that of cashmere.

3. The leather content of cashmere is higher than that of fine wool, and the rigidity of cashmere fiber is better than that of fine wool, that is, cashmere is softer than fine wool.

4. The warmth of cashmere is stronger than that of fine wool.

5. The fineness unevenness of cashmere is smaller than that of fine wool, and the appearance quality of its products is better than that of fine wool.

6. The density of cashmere is smaller than that of fine wool, and its products are lighter and thinner than fine wool products.

7. The acid resistance and alkali resistance of fine wool are better than those of cashmere, and the damage is smaller than that of cashmere when exposed to oxidants and reducing agents.

Advantage 1: Luster: wool fiber is shiny. Wool in fine is often shiny than coarser wool fibers. Fibers with high gloss have a smooth appearance.

2. Elasticity: Wool fiber has excellent elasticity and flexibility. Under standard conditions, wool fibres can be extended between 20% and 40%. In humid environments, it can extend to more than 70%. The recovery rate is superb.

After applying 2% elongation, the fibers recover immediately, with a recovery rate of 99%. Even after a 10% extension, it has a recovery rate of more than 50%, which is higher than any other fiber except nylon. The resilience of the wool is very good.

It can be crushed and crumpled back to its original shape.

3. Water absorption: the standard moisture regain rate of wool is. Under saturated conditions, wool can absorb more than 29% of its weight in water. This absorbent capacity allows wool to survive in humid, air-conditioned environments. As for the hygroscopic function, wool generates and releases heat.

4. Antistatic: Wool itself is antistatic. This is because wool is an organic substance, and there is moisture in it, so the medical community generally believes that wool is not too aggressive**.

Disadvantage 1: Because wool is a natural fiber, they do not have antibacterial and insect resistance, and the fabric will turn yellow after a long time.

2. High-end clothing woven with wool is generally dry cleaned, because the wool will shrink and pill after washing, so the wool fabric will be more troublesome to take care of.

3. The ** of wool will be relatively high, for example, the custom suits of pure wool basically start with 10,000 yuan, of course, if you want to be cheaper, you can blend wool with other chemical fibers.

The advantage is that wool itself is a material that is easily curled, it is soft and the fibers are tightly intertwined, forming a ball that can produce the effect of heat retention. The disadvantage is that it is easy to generate static electricity, so in general, try not to wear it in some combustibles.

What are the advantages and disadvantages of wool? I feel that the advantage of wool is that it is warm, but it is too heavy.

Advantages: The warmth effect is better, soft and comfortable.

Disadvantages: easy to shrink, easy to be eaten by insects, sensitive skin will have an itchy feeling. There is a special wool detergent that can be gently hand washed, shade-dried, or washed at a professional dry cleaner.

Easy to go wool, that is, the wool inside your wool clothes is easy to slip out and stick to other clothes, and it is difficult to take off those individual wool.

Advantages: It can bring out the elegance and nobility of the wearer, has good warmth, and is easy to shape.

Disadvantages: Short service life, shelf life. It is easy to generate static electricity. It is easy to cause allergies, flammable, insects, not strong, poor color fastness, friction aurora, crisp, not suitable as a material for casual clothing.

Woolen wool, also known as "wool", is a general name for fabrics woven with various types of wool and cashmere. It is usually suitable for making formal and high-end clothing such as dresses, suits, coats, etc.

Its advantages are anti-wrinkle and wear-resistant, soft to the touch, elegant and crisp, elastic, strong warmth, soft luster, warm to the touch, and not easy to wrinkle.

Its main disadvantage is that it is difficult to wash, and it is not suitable for making summer clothes.

The fineness of the wool is different: superfine wool is the finest of the wool, while ordinary wool is coarser. Comfort is different:

Sweaters made of superfine wool are not only elastic, but also very soft and delicate to the touch, which is quite comfortable to wear, but coarser wool clothes will itch after wearing. Different tastes: Superfine wool can absorb and lock in the odor molecules after sweating, so that the clothes stay fresh for a long time, while ordinary wool cannot absorb odors.

1. The fineness of wool is different: ultra-fine wool is the finest of wool, while ordinary wool is coarse.

2. Different comfort: sweaters made of ultra-fine wool not only have good elasticity, but also feel very soft and delicate, which is quite comfortable to wear, but coarser wool clothes will have an itching sensation after wearing.

3. Different taste: ultra-fine wool can absorb and lock the odor molecules after sweating, so that the clothes can stay fresh for a long time, while ordinary wool cannot absorb odors.
