Knowledge Of Clothing Health Consumption

People for clothing The pursuit is not only satisfied with the colourful variety of colors but also changes in styles. It is hoped that clothing will bring healthy enjoyment while bringing the pleasure of beauty. But many people may not be clear about how to integrate the beauty of clothing and health. Before the Spring Festival, we will prepare some clothing and health knowledge for you, and guide healthy consumption.

　　 Fabric is the key.

　　 clothes The texture is very important. People dress not only for beauty, but also for health. It is unwise to pursue fashionable and beautiful clothes without paying attention to their health.

Helps keep the body warm. clothing One of the functions. When the temperature is low, clothing should make the body's heat not lose too much. When the temperature is high, it will not interfere with the heat dissipation of the body, and prevent the adverse effects of sunlight and heat on the human body. In order to meet the above requirements, the fabric made of clothing should have the characteristics of heat preservation, air permeability and hygroscopicity.

Textiles with good thermal insulation Woollen fabrics For the best, cotton is next, and silk is the last. Because porous fabrics can store more air, thick and loose fabrics have good thermal insulation. At the same time, the color of fabrics is also related to thermal insulation. Dark fabrics are less reflective and heat absorbing. Light coloured fabrics have great reflective power and low heat absorption. Therefore, winter should be made of loose, thick, dark colored wool and cotton fabrics. In summer, thin, light and light linen and silk fabrics should be selected for clothing.

Fabrics with good breathability can emit sweat and waste gas from the skin to keep the skin dry and regulate body temperature. Therefore, we should choose a good breathable fabric for children to make clothes, adhesive tape, tarpaulin, plastic cloth and other poor ventilation, not suitable for children's clothing and children's diapers, so as not to affect the skin's metabolism, health.

The good or bad hygroscopicity is determined by the fiber properties of fabrics. Generally, wool and cotton fibers have good hygroscopicity and can be evaporated quickly to keep fabrics dry and clean.

The weaving of fabrics is also related to hygroscopicity. Knitted fabrics are more absorbent than plain fabrics. Therefore, children should wear woolen knitted clothes because they are soft and moisturizing, and have good breathability and moisture absorption. However, it should be noted that coarse wool products can not be used to avoid irritating the skin, and the moisture absorption of artificial fibers is poor, and it is not suitable for underwear. Children's underwear is better than cotton.

Chemical fiber fabrics are dangerous.

Some fabrics, such as chemical fiber products, are relaxed, soft, crisp and colorful, and have always been popular with people. However, they are irritating to the skin. In Japan, 1000 people who wore chemical fibre fabrics were investigated and found that 600 of them had abnormal skin sensation in one year. Because the raw material of chemical fiber fabrics is extracted from coal, petroleum, natural gas and other high molecular compounds or nitrogenous compounds, some of them are likely to become allergens. Once entering the body, it is easy to cause allergic dermatitis, causing itching, pain, swelling or blisters.

In addition, this type of fabric has poor ventilation and hygroscopicity, which affects sweat evaporation and skin respiration. Weak electricity on fabric, easy to absorb dust in the air, causing bronchial asthma. Some of them produce static electricity by rubbing or rubbing with the skin. Some clothes with positive charges not only have adverse effects on the skin, but also increase the blood pressure of the people. Of course, it is unrealistic to wear clothes without chemical fiber in our life. As long as our underwear does not use chemical fiber material, most of the skin damage caused by chemical fiber clothing can be avoided.

Health care of silk fabrics

Silk is known as "Queen" in textiles. People accept it not only because of its beauty, lightness, softness and smoothness, but also to a large extent its unique health care function. It can be seen under microscope that silk is composed of many slender fiber molecules arranged parallel to the long axis, leaving gaps between molecules, and water molecules can easily enter through the gaps. Therefore, silk has good moisture permeability. Even sweating in summer, silk underwear can play a role of moisture absorption and air permeability, and is conducive to regulating the temperature and humidity of the human body. Silk clothing and skin contact will not cause trouble, on the contrary, through human activities, it can massage the skin, enhance the vitality of epidermal cells, and prevent skin aging. Silk can also play an auxiliary role in certain skin diseases. Chinese medical experts have used silk underwear to treat senile pruritus and female genital pruritus, and have achieved significant antipruritic effects.

Choose fabrics according to age

Along with the growth of age, the physiological function of human body is also changing. The choice of clothing fabric should also be different. Infants with delicate skin and strong sweating function should choose soft, permeable and absorbent fabrics. Young people should pay attention to the beauty of body shape and wear tight clothing, in order to show handsome spirit. But we should pay attention to the fact that shirts and trousers should not be too tight and thin, and the texture of fabrics is also soft and soft, which is conducive to health. Middle-aged people, skin, muscle relaxation, subcutaneous fat thickening, in order not to give people the impression of bloated, clothing styles may be a little tight, but not too thin, in order to prevent vascular compression affecting blood circulation. The choice of clothing styles and colors of middle-aged people is the best way to give people a sense of youthful vigor. In the old age, all kinds of functions are obviously reduced, and the body's heat is reduced. Therefore, the clothing of the elderly should choose light, soft and warm clothing materials. The styles should be wider and more convenient and comfortable to wear.

Unknown index

I. azo dyes: after using the azo dyes containing carcinogenic aromatic amines, the dyes can be absorbed by the skin and spread in the human body after long-term contact with the human body. These dyes can be reduced to the carcinogenic aromatic amines under the biochemical reaction conditions of the normal metabolism of human body, and can alter the structure of DNA through the activation of human body, cause human diseases and induce cancer.

Two, formaldehyde: formaldehyde will cause strong irritation to human respiratory tract and skin, causing respiratory inflammation and dermatitis. In addition, formaldehyde is a strong irritant to the skin, and is also an initiator of many allergies. According to the GB18401-2003 national textile product basic safety technical specification, textiles are mainly divided into three categories: infant products are class A, formaldehyde content can not exceed 20mg/kg; products directly exposed to skin are B class, and can not exceed 75mg/kg; products with non direct contact with skin can not exceed 300mg/kg for C class.

Three, pH value: the surface of the human body is slightly acidic to prevent the invasion of germs, so the pH value of the textiles is beneficial to the protection of human body between the slight acid and neutral.

Four. Color fastness: color fastness affects not only the wearing effect, but also the dyes that are harmful to the human body. Improving the color fastness of textiles will undoubtedly reduce the risk to the greatest extent. The color fastness to saliva and perspiration of infant clothing is particularly important, because infants can absorb dyes through saliva and sweat stains.

No chemical fiber clothing can be used to prevent static electricity.

When the body moves, friction between the skin and the clothes and between the clothes and the clothes will generate static electricity. With the increasing number of household appliances and people wearing more chemical fiber clothing in winter, the static charge generated by household appliances will be absorbed and stored by the human body. In addition, indoor walls and floors are mostly insulators and air is dry, so it is more susceptible to electrostatic interference.

Because the skin of older people is less than that of young people, the aging of cardiovascular system and the weakening of anti-interference ability, the elderly are more susceptible to static electricity. The cardiovascular system has various kinds of old people. Static electricity can aggravate the condition or induce ventricular premature beat. Too high static electricity often makes people restless, headache, chest tightness, dyspnea and cough.

In order to prevent the occurrence of static electricity, indoor must maintain certain humidity, indoor must mop the floor frequently, sprinkle some water frequently, or humidifier humidifier, must bathe diligently, frequently changes clothes, eliminates the human body surface accumulates the static electricity. When the hair is not combed, the comb is immersed in the water for a moment. After the static electricity is removed, the hair can be combed and served. After you take off your clothes, gently touch the wall with your hands, touch the wall before touching the handle or faucet, and release the static electricity in the body. For the elderly, soft and smooth cotton or silk underwear and underwear should be chosen, so as not to wear chemical fiber clothing, so that the harm of static electricity can be reduced to a minimum.
