Chinese name: warm clothing mbth: There is no classification at present: definition of warm underwear: fabric, wool, bamboo charcoal, modal, lycra, kapok, precautions, purchasing skills, washing methods, common sense and fabric wool is one of the earliest natural fibers used in textiles. The history of human utilization of wool can be traced back to the Neolithic Age. It spread from Central Asia to the Mediterranean and other parts of the world, thus becoming the main textile raw material in Asia and Europe. Wool fiber has the advantages of softness, elasticity, strong hygroscopicity and good warmth retention. Because wool has natural curl, it can form many stagnant air spaces as barriers, which has good warmth retention. Wool has very good stretchability and elastic recovery, special scale structure and good flexibility, so it also has good appearance retention. The processing procedure of thermal underwear wool is very mature, and it will not deform or shrink when worn. Bamboo charcoal is known as the "black diamond" and internationally as the "2 1 century new guardian of environmental protection". Bamboo was used as raw material, and the new technology and technology of high-temperature pure oxygen and nitrogen delayed calcination were adopted to make the natural micropores of bamboo charcoal more fine and honeycomb-shaped, and then it was melt-spun with polyester modified chips with honeycomb-like micropore structure trend. The biggest difference of this kind of fiber is that each bamboo charcoal fiber has a honeycomb micropore structure that runs through the inside and outside. This unique fiber structure design can give full play to the functions of bamboo charcoal 100%. The birth of this multifunctional bamboo charcoal fiber is a revolutionary innovation of textile multifunctional raw materials. Modal fiber is a kind of regenerated cellulose fiber with high wet modulus. The raw material of this fiber is European beech, which is made into wood pulp and then processed into fiber through special spinning process. The whole production process of the fiber is pollution-free. Its dry strength is close to polyester, its wet strength is much higher than that of ordinary viscose, and its luster, softness, hygroscopicity, dyeability and dyeing fastness are better than those of pure cotton products. The fabric made of it presents silky luster, soft hand feeling, good drape and good wear resistance. It is an ideal close-fitting fabric and health care clothing product, which is beneficial to human physiological cycle and health. Lycra is just a trade name of the former Invista. Because the company occupies an arbitrary position in the spandex market, Lycra has become synonymous with almost all spandex yarns. It completely replaces the traditional elastic rubber thread. Lycra is almost an essential component in clothes with special requirements, such as gymnastics clothes and swimming suits. You can expose your curves, and the colloid can stretch freely without oppression. Lycra is not only widely used in daily clothes, but also a pet in a popular kaleidoscope made by fashion designers. According to the quality description introduced by DuPont, Lycra is different from traditional elastic fiber, its extensibility can reach 500% and it can be restored to its original state. In other words, this kind of fiber is very easy to stretch, but after recovery, it can cling to the surface of human body and has little binding force on human body. Lycra fiber can be matched with any fabric, including wool, linen, silk and cotton, which increases the close-fitting, elastic, relaxed and natural characteristics of the fabric and makes it feel more flexible when moving. And Lycra is different from most spandex yarns. It has a special chemical structure, and it will not grow mildew in a hot and humid closed space after being wetted. Kapok kapok thermal underwear is an underwear product made of kapok fiber, which has various styles, ranging from light kapok thermal underwear popular among young people to cashmere kapok thermal underwear with excellent thermal effect, especially suitable for middle-aged and elderly people. Kapok thermal underwear is a kind of green and natural environmental protection underwear product, which meets the needs of consumers who are pursuing high quality today. Kapok thermal underwear has the characteristics of lightness, softness, smooth surface, bright color, antistatic and difficult winding. In addition, because kapok thermal underwear has strong hygroscopicity and moisture conductivity, users are dry and comfortable to wear, and kapok thermal underwear is acid and alkali resistant at room temperature, and will not be moldy and moth-eaten after long-term use. Precautions How to choose high-quality thermal underwear is a very important thing for consumers. High-quality thermal underwear uses superfine fiber as the middle insulation layer, and the final clothing is soft, comfortable and warm. When rubbed by hand, it feels soft and has no foreign body feeling. The surface layer and the middle layer of the garment have a strong sense of integration and better wearability; Pure natural fabric, no uncomfortable smell. If there is obvious artificial chemical smell or musty smell, it is mostly inferior products. Never buy it. The washing method of thermal underwear is different from ordinary cotton underwear. If it is washed improperly, it will not only damage the fibers inside, but also greatly shorten its wearing life. 1. Thermal underwear cannot be dry-cleaned. The most ideal method is gentle machine washing or hand washing. 2. The water temperature should not exceed 40℃, and it is better to control it around 30℃. 3. Neutral detergent must be selected, and washing soap or detergent containing whitening agent is not allowed. Detergent should be appropriate, too much detergent will bring burden to the fabric, thus affecting the texture of underwear. 4. Detergent should not be directly dripped on underwear, but should be dissolved in warm water at 30℃-40℃ before being put into clothes. 5. Wool-containing thermal underwear is suitable for washing in warm water at about 40℃ with neutral detergent. Wash the clothes gently after soaking, and then rinse them with clear water. It is not advisable to wring them out hard. Put the washed wool thermal underwear flat in a cool and ventilated place to dry, so as to avoid exposure in the hot sun. If you want to hang it, you'd better put your sleeves on the hanger to prevent deformation. 6. Washing thermal underwear containing cotton+elastic fiber requires separate hand washing or machine washing. After cleaning, dry it indoors or outdoors in a cool place. Don't expose yourself to the sun. 7. If you need to seal, please put a desiccant to prevent the clothes from getting damp and moldy. 8. Please try to avoid rubbing against the hard coat when wearing it. 9. Please don't sleep in thermal underwear. Using common sense, consumers should pay attention to the following points when buying knitted underwear products: 1) Check whether the model and washing instructions on the clothes are correct and consistent with the logo when buying; Whether the fiber content of the clothes is consistent with that introduced by the clerk, whether it is vague and so on. 2) Learn a simple method to identify fibers. For example, wool and silk products have the smell of burnt feathers when burning; Cashmere products feel soft, without stiffness and roughness. 3) When consumers buy textiles, they should look for products with complete labels and produced and sold by regular manufacturers. For products with doubts about product quality, or products sold by vendors using new materials and technologies, consumers can consult relevant inspection agencies to prevent being cheated. 4) When consumers buy clothes and related textiles, they must identify whether the products sold by merchants are marked with the national textile product safety technical performance index GB 1840 1-2003 and its categories. If not, try not to buy it; At the same time, the products with problems should be reported to the relevant departments in time. 5) After consumers buy textile and clothing products, especially products that come into contact with the skin, they should wash and care according to the instructions on the label before wearing them, so as to avoid the unqualified products from causing great harm to themselves and reduce the use risk. 6) When consumers buy thermal underwear, they should choose rationally and compare the cost performance of products. Don't think that the more expensive the better. Correctly treat and identify the product advertisements of thermal underwear. The basic function of thermal underwear is to keep warm and comfortable, and some advertisements lack scientific basis. Don't blindly believe in the so-called high-tech concept. When choosing thermal underwear, the fabric should be soft, comfortable, light, elastic and warm. The thermal effect of thermal underwear is inversely proportional to air permeability (fabric density). 7) Thermal underwear is different from ordinary cotton underwear. If it is washed improperly, it will not only damage the fibers inside, but also greatly shorten its wearing life. Thermal underwear can't be dry-cleaned. The ideal method is gentle machine washing or hand washing. The water temperature should not exceed 40℃, and it is better to control it at around 30℃. Be sure to choose neutral detergent, detergent should be moderate, too much detergent will bring a burden to the fabric, thus affecting the texture of underwear. Detergent should not be dripped directly on underwear, but should be dissolved in warm water at 30-40℃ before being put into clothes. Wash the clothes gently after soaking, and then rinse them with clear water. It is not advisable to wring them out hard. Put the washed wool thermal underwear flat in a cool and ventilated place to dry, so as to avoid exposure in the hot sun. If you want to hang it, you'd better put your sleeves on the hanger to prevent deformation. Please try to avoid rubbing against the hard coat when wearing it, and don't sleep in thermal underwear. For so-called functional underwear, such as far-infrared underwear, because some additives are made by coating treatment, the performance is easy to deteriorate after repeated washing, so it is not suitable for frequent washing.
