Knowledge of cotton fabric, in real life, cotton fabric is also a common fabric in our life. This kind of fabric is very elastic and can generally be used to make clothes. Let's share the knowledge of cotton fabric for everyone.

Knowledge of cotton fabric 1 cotton fabric is a kind of clothing fabric that we contact more. There are many definitions of cotton, but the fabric with cotton content between 95%- 100% is preferred. The extremely high cotton content will surprise people that the fabric can give full play to the characteristics of cotton fibers.

Cotton varieties. It is divided into fine wool cotton and long wool cotton. Fine cotton is divided into 1 ~ 7 grades, and long-staple cotton is divided into 1 ~ 5 grades. The larger the series, the worse the quality, that is, 1 is the best. At the same time, cotton prices in different producing areas will be different. For example, the quality of Egyptian long-staple cotton is better than Xinjiang long-staple cotton.

Spinning quality. Spinning can be divided into combing and carding. Comb is graded by spinning machine, impurities are cleaned and then sorted. Generally, the length of single yarn is more than 25mm, which has good luster, smoother fabric and higher grade. Moreover, because the single yarn is longer, it is not easy to pilling after wearing it.

Yarn density. Fabrics with high count yarns are generally thinner than ordinary yarns. Yarns below 40 are ordinary yarns (excluding 40 yarns), and yarns above 40 are high count yarns. Of course, the higher the yarn count, the more expensive the cotton yarn is. The fabric marked 40S, 133*72 on Taobao costs only about 100 yuan, which is basically a "free upgrade". Just give it to you 128*68.

With the same yarn count, the quality of twill yarn is better than plain yarn, and of course the price will be different.

Dyeing materials. Low-priced fabrics, the first consideration is cost, so inferior dyes will be used, and the fabric itself will also have problems such as formaldehyde, PH value, color fastness, and decomposable aromatic amine carcinogens exceeding the standard.

Printing and dyeing methods. Printing and dyeing can be divided into pigment printing and reactive printing. Now the imitation printing on the Internet is still pigment printing. The quality and cost of reactive printing and dyeing are higher than that of pigment printing because of different processes and prices.

Of course, there are also some factors that determine the quality of fabric, that is, the process in the production process, such as finishing, singeing, stretching, calendering and so on. And specific technical details determine the cost.

Characteristics of cotton fabric

Hygroscopicity: Mainly because cotton fibers contained in cotton fabrics have good hygroscopicity. Under normal circumstances, the fiber can absorb water into the surrounding atmosphere, and its moisture content is 8- 10%, so it makes people feel soft but not stiff when touching the skin. If the humidity of cotton cloth increases and the surrounding temperature is higher, all the water contained in the fiber will evaporate and disperse, so that the fabric can keep water balance and make people feel comfortable.

The content of cotton is higher than that of pure cotton (cotton content >: 75%), which has better moisture absorption and moisturizing performance. Because the moisture content of cotton fiber is about 10%, it can absorb moisture in the air. The fabric with this moisture content is very friendly to human skin, which is why cotton fabric is very comfortable and will not feel dry. At the same time, cotton fiber is a porous structure, and air can be stored between fibers, which also makes cotton fabric have a very outstanding performance in moisturizing.

Moisture retention: Because cotton fiber is a poor conductor of heat and electricity, the thermal conductivity is extremely low, and because cotton fiber itself has the advantages of porosity and high elasticity, a lot of air can accumulate between fibers, and air is a poor conductor of heat and electricity, so cotton fiber textiles have good moisture retention, and wearing pure cotton clothes makes people feel warm. Moisture absorption and moisture retention are mainly due to the good moisture absorption of cotton fibers contained in cotton fabrics, with a general moisture content of 8- 10%.

Heat resistance: Many people think that cotton is easy to catch fire, so the heat resistance is not so good, but experiments show that cotton products only evaporate water at 100 degrees, and the fiber structure has not changed much. Cotton fabric has good heat resistance. When the temperature is lower than 1 10℃, only the moisture on the fabric will evaporate, and the fiber will not be damaged. Therefore, the pure cotton fabric has no influence on the wearing, washing, printing and dyeing of the fabric at room temperature, thus improving the washing resistance and durability of the pure cotton fabric.

Warm: Both cotton and cotton fabrics have good warm-keeping effect, and many winter clothes or winter bedding are made of cotton.

Alkali resistance: cotton fiber has good alkali resistance, even strong alkali will not damage the fiber. This property is conducive to the washing and disinfection of clothes, as well as the dyeing, printing and various processing of cotton textiles, so as to produce more new cotton varieties and clothing styles, but cotton fabrics should avoid contact with acidic substances.

Hygiene: Cotton fiber is a kind of natural fiber, and its main component is cellulose. This natural plant fiber will not cause harm to human body, nor will it produce other chemicals during processing. After many tests and practices, the cotton fabric has no irritation and negative effects when it comes into contact with the skin, and it is beneficial and harmless to the human body after long-term use, with good sanitary performance. Therefore, many infant clothes will be made of pure cotton or pure cotton fabrics.

The main disadvantages of cotton:

The elasticity is not very strong, there will be some shrinkage or pilling after washing, and the wrinkle resistance is also very general. These shortcomings will affect the appearance of cotton-padded jacket to varying degrees. It's easy to wrinkle, and only when you take it off and wash it will wrinkles disappear. Therefore, when drying, we should tidy up cotton clothes and dry them naturally.

Washing method of cotton fabric;

In washing, cotton is similar to cotton, and there are not so many rules and regulations. It is best to wash with neutral detergent, hand washing or machine washing. When drying, it is best to turn the back of the clothes outward to avoid yellowing and hardening.

Knowledge of cotton fabrics 2 1. Cotton fabric refers to clothes or textiles with cotton content of 95%- 100%.

2. Good sanitary performance. Cotton fiber is a kind of natural fiber, its main component is cellulose, containing a small amount of waxy substances, nitrogen-containing substances and pectin. After many tests and practices, the pure cotton fabric has no irritation and side effects in contact with the skin, and it is beneficial and harmless to the human body for a long time, with good sanitary performance.

3. Good thermal insulation performance. Because cotton fiber is a poor conductor of heat and electricity, the thermal conductivity is extremely low, and because cotton fiber itself has the advantages of porosity and high elasticity, a lot of air can be accumulated between fibers, and air is also a poor conductor of heat and electricity, so cotton fiber textiles have good thermal insulation performance, and wearing pure cotton clothes makes people feel warm.

4. Strong alkali resistance. Cotton fiber has strong alkali resistance. Cotton fiber will not be damaged when it is in alkaline solution. This property is conducive to washing away pollution, disinfection and impurity removal after taking. At the same time, cotton textiles can be dyed, printed and processed to produce more new cotton varieties.

5. It has good hygroscopicity. Under normal circumstances, fiber can absorb water into the surrounding atmosphere, and its water content is 8- 10%, so it contacts with human skin, making people feel soft but not stiff. If the humidity of cotton cloth increases and the surrounding temperature is higher, all the water contained in the fiber will evaporate and disperse, so that the fabric can keep water balance and make people feel comfortable.

6. Good heat resistance. When the temperature is lower than 1 10℃, only the moisture on the fabric will evaporate without damaging the fiber. Therefore, cotton fabric has no influence on the wearing, washing, printing and dyeing of the fabric at room temperature, thus improving the washing resistance and wear resistance of the cotton fabric.

Cotton fabric knowledge 3 cotton four-piece suit?

Of course. Cotton four-piece suit is the most popular material in the four-piece suit, and it is the first choice for thousands of households. Very soft and comfortable, it is recognized as a comfortable fabric, and it is also the most common four-piece fabric in our family. Pure cotton fabric occupies a dominant position in bedding.

Four advantages of pure cotton four-piece suit

1, comfortable and soft

The four-piece cotton suit feels very comfortable and soft, especially skin-friendly. But also is suitable for all people, has no irritation to human skin, and does not cause redness, swelling and allergy to our skin. In the dry season, it is not easy to have static problems, which is very comfortable.

2, moisture absorption and ventilation

Another biggest advantage of the cotton four-piece suit is that it absorbs moisture and breathes, absorbs water and sweat, and is very practical in the south. Winter in the south is wet and cold, and the humidity in the air is relatively high. The four-piece cotton suit has good moisture absorption and breathability, so we won't feel bored even if we cover the quilt. Let's take this for example. The mobile phone is flooded. I suggest you nest it in a quilt. The reason lies in its hygroscopicity.

3, warm effect

The warm effect of cotton cloth is also good. In the cold winter, this four-piece suit can make us very warm when we sleep. Some people will buy some polyester four-piece suits, and when they lie on them, they will find that the whole bed is cold and the temperature rises slowly. It may be more comfortable to sleep in summer, but it is better to keep warm with a four-piece cotton-padded jacket in winter.

4, good alkali resistance

The cotton four-piece suit also has good alkali resistance (acid and alkali resistance refers to the endurance of the object to soaking in acid or alkaline water), even if it is washed with detergent, these patterns will not be washed off. At the same time, it also allows us to disinfect the quilt cover better and make users feel more at ease.

Disadvantages of pure cotton four-piece suit

The four-piece suit of pure cotton fabric also has some shortcomings. The biggest disadvantage is that it will shrink after frequent cleaning, so you must pay attention to this when making cotton bedding, and it is recommended to customize it appropriately. Another disadvantage is poor gloss.
