How to distinguish polyester, wool, cotton

1. It can be distinguished by the method of fire, if it is cotton thread, it is ash after burning, and there is the smell of burning paper; Polyester fibers form hard balls after burning. When the wool is burned, the residue is lumpy, and there is roast chicken.

The smell of hair (the smell of burning proteins).

2. Fluorescence method: the use of ultraviolet rays.

Fibers are irradiated by fluorescent lamps, and fibers are identified according to the different luminescent properties of various fibers and the different fluorescent colors of fibers. The fluorescence characteristics of cotton and polyester are as follows: cotton, pale yellow, polyester fiber, white light and bright on a sunny day.

3. Density gradient method.

It is to identify fibers according to the characteristics of various fibers with different densities, the specific gravity of cotton is:, and the specific gravity of polyester is:. The specific gravity can be read directly from the density gradient tube, and the above number can be compared to know which polyester is used.

Distinguish polyester, wool, cotton can be distinguished by fire, this method is very common and simple:

If it is cotton, it will be ashes after burning, and there is a smell of burning paper; Polyester fibers form hard balls after burning. Take a small sample and ignite it, the composition of cotton thread is cellulose, and the component of wool thread is protein. Therefore, when the wool is burned, the residue is lumpy, and there is the smell of burning chicken feathers (the smell of protein burning), while the residue of cotton thread is powdery when burning, and there is no obvious odor.

Smell of burning, polyester pilling, wool smells of burnt feathers, and cotton thread smells of burning paper.

After lighting these 3 things, smell the smell to distinguish them.

The wool thread is very soft and smooth, and the acrylic is relatively hard, and it can be distinguished by fire.

When burned with fire, it is wool that can be burned into powder, and it is not wool that is inseparable from each other, and it is wool that can be twisted into powder.

Acrylic fiber has unique excellent characteristics very similar to wool, soft feel, good bulkiness and good elasticity. The feel and appearance are very similar to wool, so it is called "artificial wool". It has good dyeing performance, bright colors and strong warmth.

The wool thread is very soft and smooth, the clear fiber is relatively hard, the smell of wool and acrylic is different after burning, and the smell of wool is strong and smelly. Acrylic is burned into black, hard granules.

Woolen yarn and cotton thread are two commonly used wires, and their differences are as follows:

1.Material: Wool is often composed of wool, mohair, rabbit hair, cashmere and other materials, while cotton thread is made of cotton fibers.

2.Texture: The wool is soft and elastic, suitable for knitting, weaving, crocheting and other handmade products, which can give the products a strong sense of three-dimensional and fluff. Cotton threads are smoother and delicate, making them suitable for intimate clothing and delicate handmade work.

3.Thermal performance: grinding stupid because the wool itself has fluff, so the warmth performance is better, suitable for making winter clothes; Cotton thread, on the other hand, is more suitable for summer clothing.

4.Moisture absorption: Wool has better moisture absorption than cotton yarn and is able to absorb moisture that penetrates into the surface, thus ensuring dryness and comfort.

5.Difficulty of maintenance: The maintenance of wool is relatively difficult, and it is necessary to pay attention to the care, dry cleaning and insect control of fluff under the filial piety cover; Cotton threads are relatively easy to maintain and can be washed with water.

To sum up, wool and cotton yarn have certain differences in material, texture, warmth, moisture absorption and maintenance difficulty, etc., and the choice of which wire should be considered according to the specific use and needs.

Whether it's good or not is up to the customer. Well, for you, what's right for you is the best.

Polyester thread and cotton thread are basically used in sewing machines, polyester thread has high strength, many colors, and is cheap. Generally, polyester sewing thread is basically used for sewing thread on the market. Cotton thread is some relatively high-end product fabrics, which are used for sewing clothing cuffs with strict requirements.

Polyester thread.

Of course, the cotton thread is better, the cotton thread is closer to the skin, and it will not make you feel uncomfortable, but the toughness of the polyester thread is better.

Is it better to have a polyester thread or a cotton thread, so what is it used for? If you do the back, it is still good cotton thread, but if you sew clothes, it is still polyester thread, polyester thread is more resistant, and you can use it to make clothes. It takes a little longer to resist Peng Mo.

Pure cotton thread he is better fitting, but. I don't like to use it. Use.

Good and bad. So what's this for? If.

See what it does?

Each has its own benefits. Cotton is more comfortable, and polyester is stronger.

I think it's better to compare these two points with pure cotton, because the quality of pure cotton is very good, and it is also very strong, and it will feel very comfortable in the process of use.

The polyester thread is strong, not easy to fade, and the color is bright. Pure cotton thread is easy to break and fade.

Cotton thread is made of cotton or other plant fibers, the raw material of wool is animal hair, wool usually refers to wool spun thread, but also refers to wool and artificial wool mixed spun thread or spike artificial wool spun thread.

Cotton thread: Cotton thread is a thread made from cotton fibers. There are two kinds of cotton thread for binding, which are good and not varnished, and there are two kinds of packaging forms: straight shaft type and tower shaft type. The tower shaft type is mostly used for wire locking.

Wool: Wool usually refers to yarn spun from wool, and there are also threads spun from different types of chemical fiber materials, such as: acrylic fiber, polyester fiber, persian fiber and so on. Or as a negative word for a suspected lead.

Cotton thread is made of cotton or other plant fibers, the raw material of wool is animal hair, wool usually refers to wool spun thread, but also refers to wool and artificial wool mixed spun thread or artificial wool spun yarn.

Cotton thread: Cotton thread is a thread made of cotton fiber. There are two kinds of cotton thread for binding: glazing and non-glazing, and there are two types of packaging forms: straight shaft type and tower shaft type. The tower shaft type is mostly used for wire locking.

Yarn: Wool usually refers to yarn spun from wool, and there are also threads spun from different types of chemical fiber materials, such as: acrylic fiber, polyester fiber, persian fiber, etc. Or as a kind of negation.

1. The feel is different. The wool thread is very soft and smooth, and the clear and slippery is relatively hard.

2. The smell of wool and acrylic is different after burning. The smell of wool is strong and foul. Odorless or the smell of burning paper is cyanamide thread.

3. The state is different after the fire. It is wool that is inseparable from each other and can be twisted into powder. After combustion, the black, hard granular form is acrylic.

4. ** aspects. The ** of acrylic thread is very cheap, a fraction of that of wool thread.
