Excuse me, how to identify cotton sheets, quilts and underwear?

You should have a certain recognition ability when buying clothes. If you love pure cotton, you need to know something about it.

I also like pure cotton clothes very much. Because of its health, I feel comfortable and safe inside. Generally speaking, I don't have any special skills, but I can easily identify them, because many of my clothes are pure cotton or close to pure cotton, and I can find the feeling after wearing them for a long time ~ Generally speaking, pure cotton clothes are easy to deform and shrink, and they are astringent, not easy to wash, not as refreshing and easy to rub as chemical fiber clothes; Moreover, pure cotton clothes are easy to fade or cross-color with other clothes when washing.

Here are some characteristics of pure cotton I found for your reference.

Characteristics of pure cotton fabric:

(1) hygroscopicity: cotton fiber has good hygroscopicity. Under normal circumstances, fiber can absorb water into the surrounding atmosphere, and its water content is 8- 10%, so it contacts 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.

(2) 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 large amount 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 clothing makes people feel warm.

③ Heat resistance: Pure cotton fabric has good heat resistance. When the temperature is lower than 1 10℃, only the moisture on the fabric will evaporate without damaging the fiber. 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 wear resistance of the pure cotton fabric.

(4) Alkali resistance: Cotton fiber has strong alkali resistance, and the fiber will not be damaged in alkali solution. This property is beneficial to wash away the pollution after taking, disinfect and remove impurities, and can also dye, print and process various cotton textiles to produce more new cotton varieties.

⑤ Hygiene: Cotton fiber is a natural fiber, the main component is cellulose, and there are a few waxy substances, nitrogen-containing substances and pectin. After many tests and practices, the pure 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.

Chemical fiber is the general name of textile fiber which is made of natural polymer or synthetic polymer and processed by chemical process.
