How to distinguish wool and cashmere? How to divide the quality grades of wool and cashmere

We all have a better understanding of cotton, hemp and other fabrics. Spring and autumn is the season for selling all kinds of sweaters. Many sellers have marked mohair, Merino wool, cashmere and so on in a dazzling position. Today I will introduce how to identify the true and false wool and cashmere? How to divide the quality grades of wool and cashmere?

Characteristics and differences of cashmere and wool:

First of all, wool and cashmere are not the same concept. Generally speaking, we can think of the difference between feather and down. Wool and cashmere are both natural fibers, but they are different in thickness. They can be calculated by the number of fibers. The higher the number of fibers, the finer they are. The better the handle and warmth retention performance are, which means the more expensive they are. Let's say that if you make two identical coats out of wool and cashmere, cashmere coat will keep warm eight times as much as wool coat, and its weight is only one fifth of wool coat.

Classification of quality grades of wool and cashmere

The same is wool, different varieties of wool, the wool fiber thickness is also different. If the number of good wool exceeds 100, it is close to the quality of cashmere. If you make a list of the better wool fabrics on the market, the quality from low to high is as follows:

Mohair coarse wool (Angora goat hair, coarse wool over 45 microns in diameter)

Merino wool (fine wool mainly produced in Australia, with a diameter range of 18-25 microns)

Mohair fine wool (Angolan 1-year-old goat hair, 10-30 microns in diameter)

Cashmere cashmere cashmere (about 19 microns in diameter)

Several points for attention:

1. The better the quality of wool and cashmere products, the closer the color is to the light color of the original wool. Please refer to the color of Hermes cashmere scarf. Which colors are gorgeous are mostly blended or inferior fabrics;

2. For the common ring velvet of scarves, we should pay attention to the thin and dense ones, and the thin and sparse materials with light transmission are poor;

3. Cashmere products should be maintained and should not be worn for a long time. It's better to put them flat for one day to prevent them from becoming loose, because cashmere fiber is elastic and can be naturally restored.

4. The ingredient label on the tag is the place to observe the content of wool and cashmere (the handle is not reliable in many cases, and the handle of the chemical fiber fabric made by scientific and technological means will even be slightly better). Some excellent wool and cashmere fabrics will be sewn with additional fabric marks as the main label. When you encounter such fabrics, you should try your best to accept them. They are usually good fabrics;

There are two kinds of situations where there is no label for washing label fabric composition: if domestic brands are mostly pure fiber spinning wool fabrics, they will not be labeled at all; if some original cashmere fabrics do not have label for washing label, they need experience such as hand feeling.

How to distinguish between wool and cashmere?

The Mohair on the market is mostly imitation Mohair made of chemical fiber. After washing, you can find that the hand feel of fake Mohair is obviously worse; there is a slight crackle after rubbing the fake Mohair with cotton cloth for many times; the simplest way is to cut off a small section and ignite it. The real mohair burns slowly and has the smell of charred feathers and turns into powder. The fake Mohair burns and agglomerates and has the smell of plastic. The above methods can be used to identify the true and false wool and cashmere.

Use a lighter to burn wool vertically from the bottom. Blended yarn, wool, cashmere, etc. all have protein, and there will be a bad smell when burning. The key is that after lighting, leave the fire source, and it will go out quickly. At the same time, when you pinch it, the remaining product becomes powder, and there are no other impurities, which indicates that it is pure wool. But after lighting, leave the fire source, and the flame still burns up along the wool. How much is there How much to burn, until all the wool is burned, this is pure cashmere.

For wool and cashmere mixed with rabbit hair, the above burning methods are invalid, but good wool and cashmere are not afraid of washing, and rabbit hair is more spoiled and easy to tangle after washing.

Now many cashmere sweaters and scarves are made of cashmere yarn. How to distinguish the true and false cashmere thread? Is the fine wool thread sold at a high price as cashmere thread? The following methods are simple and practical!

The characteristics of cashmere thread: take a thread, gently and effortlessly pull can pull off a section of wool, no stretch sense, that is cashmere;

The characteristics of wool thread: if it is tight when it is pulled off, it will take a lot of effort, which is usually wool;

Characteristics of blended chemical fiber line: if it has tensile property, it must be chemical fiber.

Other precautions: cashmere or wool, the line is very simple to pull off, just like the feeling of pulling cotton ball. If there is stretching, it is similar to the feeling of slight elasticity. When pulling, the fingers holding the thread will still have a little pain, or even a short line impression. In the purchase can also pull a little bit more expensive line and the cheapest line, compare.
