Introduction: Everyone says that it is better to wear pure cotton clothes because pure cotton is more comfortable, clean and breathable. Some friends want to know more about pure cotton. So, do you know whether pure cotton gets smaller or larger the more you wash it? Do pure cotton clothes get smaller or larger the more they are washed? Regarding this question, many friends want to know the answer. Let’s find out quickly.
Does pure cotton get smaller or larger the more you wash it?
Pure cotton
The more you wash it, the smaller it gets. This is mainly because the pure cotton fabric has shrunk to a certain extent.
In order to reduce costs, some manufacturers now use chemical fiber ribs and piping on the collars of pure cotton T-shirts, the waistbands of cotton underwear, leg tubes and other parts that are easy to wear, so these parts are more likely to be washed. The bigger.
Therefore, do not use excessive force when washing clothes, only scrub gently. After washing, do not squeeze too hard and press the water with your hands. It is best to lay it flat and dry it in the sun to keep the original shape as much as possible.
The shrinkage rate of pure cotton clothing is 2% to 5%, which has been specially processed or washed. Pure cotton has a large shrinkage rate, and cotton fibers are highly absorbent. When they absorb water, the cotton fibers swell, causing the cotton yarn to shrink and deform. The water temperature can be controlled below 35℃ when washing. It is not suitable to soak in detergent for a long time. When ironing, the temperature should be below 120℃. When drying clothes, keep them in a cool place or in the sun.
Pure cotton fabric is a fabric made from cotton as raw material and produced through textile technology. It has the characteristics of moisture absorption, warmth retention, heat resistance, alkali resistance, and hygiene. Generally speaking, pure cotton fabrics have better moisture absorption and heat resistance, and are comfortable to wear. Work clothes in some industries that require high hygroscopicity of clothing can be processed with pure cotton fabrics. For example, summer school uniforms, etc.

Characteristics of pure cotton
Hygroscopicity
Cotton fiber has good hygroscopicity. Under normal circumstances, the fiber can absorb moisture from the surrounding atmosphere. Its moisture content is 8~10%, so when it contacts human skin, it makes people feel soft but not stiff. . If the humidity of cotton cloth increases and the surrounding temperature is high, all the moisture contained in the fiber will evaporate and dissipate, keeping the fabric in a water balance state and making people feel comfortable.
Warmth retention
Because cotton fiber is a poor conductor of heat and electricity, the thermal conductivity coefficient is extremely low, and because cotton fiber itself is porous and has high elasticity, it can accumulate between fibers. A large amount of air, and air is a poor conductor of heat and electricity. Therefore, pure cotton fiber textiles have good warmth retention properties. Wearing pure cotton fabric clothing makes people feel warm.
Heat resistance
Pure cotton fabrics have good heat resistance. When the temperature is below 110°C, it will only cause the water on the fabric to evaporate and will not damage the fibers. Therefore, pure cotton fabrics are resistant to heat at room temperature. It has no effect on the fabrics during wearing, washing, printing and dyeing, thus improving the washability and wearability of pure cotton fabrics.
Alkali resistance
Cotton fiber has greater resistance to alkali. In the alkali solution, the fiber will not be damaged. This property is beneficial to the cleaning of pollution after consumption. , disinfect and remove impurities, and also dye, print and process pure cotton textiles to produce more new varieties of cotton fabrics.
Hygiene
Cotton fiber is a natural fiber, its main component is cellulose, and there are also a small amount of waxy substances, nitrogen-containing substances and pectin. Pure cotton fabrics have been tested and practiced in many aspects. There is no irritation or negative effects when the fabric comes into contact with the skin. It is beneficial to the human body when worn for a long time and has good hygienic performance.

What is the difference between pure cotton and 100% cotton
1. The difference in cotton content
Pure cotton fabrics are generally made of cotton, and their cotton content is very high. When the cotton content is above 70%, it is called pure cotton.
Cotton fabric is generally a term used in many home textiles and other materials, so cotton means that the fabric is made of 100% cotton.
2. Differences in terms
Cotton simply means that the fabric is 100% cotton.
Pure cotton means that all the fabrics of the whole piece are 100% cotton.
3. Differences in processing
Pure cotton fabrics are prone to wrinkles due to different processing methods.
Cotton fabrics are not prone to wrinkles due to different processing methods.
Washing and maintenance
1. Cotton fabrics have strong alkali resistance, not acid resistance, and good high temperature resistance. Various detergents can be used, but try not to use detergents.For powder, it is best to use transparent soap or soap powder or soap paste. First use warm water to dissolve the detergent, then soak the clothes after it cools down. Not suitable for chlorine bleaching;
2. Before washing, colored clothes can be soaked in water for a few minutes, but not for too long to avoid color damage.
3. White clothes can be washed at high temperature with a strong alkaline detergent to have a bleaching effect;
4. Underwear should not be soaked in hot water to avoid coagulation of the protein in the sweat stains. And adhere to the clothing, resulting in yellow spots.
