Is pure cotton really good for skin?

In our daily life, whether we buy clothes or bedclothes, but the preferred material for close contact with skin is undoubtedly pure cotton. Due to the fact that natural fibers are skin friendly, silk, cotton, hemp and other natural fiber materials are widely used in skin friendly textiles, among which cotton is the most widely used. Skin friendly textile mainly refers to the comfort and fit of fabric and skin contact. Skin friendly textiles refer to textile clothing and other textiles with specific requirements in materials and processing technology, which are comfortable and breathable. The concept of “skin friendly” textiles in the market are mainly limited to cotton, silk, viscose fiber, etc., which have not been elaborated in detail in China, and there is no unified index for performance characterization of skin friendly textiles. Therefore, some “conceptual” marketing can take advantage of these loopholes to confuse consumers to pay for their money. < / P > < p > most of them want to be “pure”, so the more single the composition, the more reassured you are. But do you really understand the true meaning of “pure”? Xiaohua has heard such a saying: when the fiber content of a product reaches 60% or more than 75%, it can be called pure cotton; and then it is known that the product with 100% cotton fiber content can be called pure cotton. As a result, many consumers are biased by this statement. Most of them feel that they buy pure cotton, but they are not happy. < / P > < p > in fact, there is no basis for this. According to the national standard GB / T 29862-2013, “100%”, “pure” or “full” is used to represent the fiber content when the product or a part of the product is completely composed of one fiber, and the fiber content tolerance is 0. < / P > < p > you can see here that even if the label says 75% cotton content, the remaining 25% is made of other fiber materials, which can not be called pure cotton in the true sense. < p > < p > hygroscopicity: cotton fiber has good hygroscopicity. Therefore, contact with sweat skin, there will be no stiff discomfort. If the humidity increases and the ambient temperature is high, all the water absorbed in the cotton fiber will evaporate and disperse, which can keep the textile in balance. Thermal insulation / air permeability: the air permeability of a fabric is determined by the number of warp and weft yarns and fiber gaps in the fabric, and also related to such factors as warp and weft density, warp and weft yarn count, yarn twist, etc.; in addition, it is also related to fiber properties, yarn structure, fabric thickness and volume weight. In other words, we need clothes with good air permeability in summer and warm keeping performance in winter, so we can use different quality cotton and different knitting processes to produce seasonal textiles. < / P > < p > heat resistance: in case of high temperature below 100 ℃, the water on the fabric will evaporate and the fiber itself will not be damaged. Therefore, the use of cotton fabric at room temperature, washing and dyeing have no effect on the fabric, thus improving the washing and wear resistance of pure cotton fabric. Sanitary: cotton fiber is a natural fiber, its main component is cellulose, containing a small amount of waxy substances, nitrogen-containing substances and pectin. The pure cotton fabric has been inspected and practiced in many aspects. It has no irritation and side effect when it contacts with skin. It is good for human body to wear it for a long time and has good sanitary performance. < / P > < p > it is easy to wrinkle, difficult to smooth, shrink, lack of elasticity and easy to deform, especially for summer wear, because the fabric is thin. Pet owners at home should have a deep understanding, it is easy to stick hair, but it is difficult to remove; it is not acid resistant. When acid is accidentally put on clothes, it should be cleaned in time to avoid damage to clothes by acetic acid. In addition, both textile technology and material research and development are mature. Textiles that can be sold in regular channels are definitely safe and harmless. In fact, there is no problem with softness and comfort, frequent cleaning and proper replacement, and it is unnecessary to pursue pure cotton excessively. < / P > < p > due to its characteristics, it can not be dried out quickly after strenuous exercise, and the sweat will be fully absorbed in the fiber and in close contact with the skin, which may cause folliculitis in a long time, which can not be ignored. < / P > < p > and after absorbing water, the pure cotton material has a certain degree of softness, but it is not comfortable when it is completely dry. In addition, our armpits, thigh roots and other parts are relatively delicate. Long time friction with the skin may damage the skin barrier and cause skin lesions. < p > < p > finally, for drivers and other job groups who need to work for a long time and can’t move freely or are restricted by environmental factors, pure cotton underwear also has hidden dangers. Because of being in a confined space and in close contact with your private parts for a long time, underwear soaked with sweat, body fluids and secretions is of course the best place for bacteria to breed.
