The difference between cotton and pure cotton, what is the percentage of cotton content respectively

I do textiles, and I will briefly talk about the difference between cotton and pure cotton. There seems to be no difference between pure and pure in a literal sense, and there is a difference in the textile industry. The cotton is spun into cotton yarn according to the product specifications, which has two grades: cotton and pure cotton.

The cotton blend of cotton yarn contains chemical fibers or other non-cotton components to be strong.

The strength of the yarn, so the cotton content of the whole cotton is not 100, and there is only one substance in the cotton content of pure cotton: cotton. It is not doped with non-cotton substances, so the cotton content of pure cotton is 100%.

As for the cotton content of the whole cotton, it is changed according to the value of the non-cotton content that needs to be mixed with the product. Due to my lack of qualifications, the above information is for reference. I also hope that there will be professionals to correct or supplement!

Nowadays, when many people buy clothes, they always pay attention to pure cotton and cotton, but they don't know very well whether 100% cotton is pure cotton or cotton? 100% cotton belongs to all cotton, all cotton means that the fabric of the whole item is all 100% cotton, but it should be noted that all cotton does not mean that 100% is definitely cotton, and some other fibers will be added in it, when the cotton content in the fabric exceeds 65%, this is the range of cotton. There are many types of cotton, such as labor cloth, corduroy, twill, etc., which is a term used in clothes or other fabric materials.

If it is a cotton fabric, it will not wrinkle easily due to the different processing methods.

100% cotton is all cotton.

In the general concept, pure cotton means that the raw materials of the product are all cotton, but pure cotton is not equal to 100% cotton. Real 100% cotton is collectively referred to as cotton, and generally the cotton content of more than 75% can be called pure cotton.

Therefore, only when the fabric is 100% cotton, or when the cotton fabric is made of cotton, including plain cloth, poplin, twill, labor cloth, etc., can it be called "pure cotton" or "cotton".

The method of judging cotton products

1. Look at the label.

Although the banner of the merchant may be pure cotton, the specific cotton content will be indicated on the product label.

2. Look at the feel.

The cotton cloth surface is soft and shiny, soft to the touch, poor elasticity, easy to wrinkle, and the crease is not easy to return to its original state.

3. Combustion method.

Pure cotton products are close to the flame, do not shrink or melt. It burns quickly after contact with the flame, the flame is orange yellow, has blue smoke, and has few ashes, and is linear. The ash is fine and soft, and it is easy to form a powder when touched.

100% cotton"with"220 grams of pure Yu Zhi cotton"These two concepts are not at the same level, so they are not comparable to each other and cannot be directly compared.

100% cotton"It refers to the amount of cotton in a fabric, which means that the fabric is made from 100% cotton. While"Cotton 220 grams"It refers to the weight of this fabric per square meter, that is, there are 220 grams of fabric per square meter.

When buying cotton fabrics, in addition to seeing whether it is labeled"100% cotton"In addition, you also need to pay attention to other indicators, such as texture, feel, breathability, sweat absorption and other characteristics, in order to better choose the fabric suitable for your own vertical purity.

Pure cotton is 100% cotton. Pure cotton simply means that the fabric is 100% cotton, and pure cotton fabric is a textile made of cotton as raw material, through a loom, and intertwined by the vertical and horizontal ups and downs of warp and weft yarns. There are many varieties of cotton fabrics, with different colors.

According to the dyeing method, it is divided into primary color cotton, dyed cotton, printed cotton, and yarn-dyed cotton.

Pure cotton: cotton fiber has good moisture absorption, under normal circumstances, the fiber can absorb water to the surrounding atmosphere, its moisture content is 8-10%, so it contacts people's **, so people feel soft but not stiff. If the humidity of the cotton cloth increases and the surrounding temperature is high, all the moisture contained in the fiber will evaporate and dissipate, so that the fabric will maintain a water balance and make people feel comfortable.

Because cotton fiber is a poor conductor of heat and electricity, the thermal conductivity coefficient is very low, and because the cotton fiber itself has the advantages of porosity and high elasticity, a large amount of air can accumulate between the fibers, and the air is a bad conductor of heat and electricity, therefore, pure cotton fiber textiles have good moisturizing properties, and wearing pure cotton clothing makes people feel warm.
