Several Common Fabrics Of Thermal Underwear

　　 wool

Human beings are spin One of the earliest used natural fibers. As a result, fine wool can be used as a major textile material in Asia and other parts of the world. Wool fiber is soft and elastic, with strong hygroscopicity and good warmth retention. Because wool has natural curl, it can form many non flowing air areas as a barrier, which has good thermal insulation. Wool has very good tensile and elastic recovery, and has a special wool scale structure and excellent bending, so it also has a good appearance retention. At present, the processing process of thermal underwear wool has been very mature, wearing no deformation, no shrinkage.

　 Bamboo charcoal

Known as "black diamond", it is known as "the new guard of environmental protection in the 21st century". It is made of bamboo by using pure oxygen high temperature and nitrogen blocking delay calcination process and new technology, which makes the inherent micropores of bamboo charcoal more refined and honeycomb, and then melt spinning with polyester modified chips with honeycomb structure trend. The biggest difference of the fiber is that each bamboo charcoal fiber has a honeycomb structure running through the inside and outside. This unique fiber structure design can make the bamboo charcoal function 100% play out. This multi-functional bamboo charcoal fiber is a revolutionary innovation of textile multi-functional raw materials.

　　 Bamboo charcoal fiber The main performance is, super adsorption capacity: bamboo charcoal adsorption capacity is more than 5 times of charcoal, formaldehyde, benzene, toluene, ammonia and other harmful substances and dust can play the role of absorption, decomposition and deodorization. For example, the ammonia removal rate of ordinary viscose fiber is only 17.4%, while that of bamboo charcoal viscose fiber is 54%. Far infrared emission, thermal storage: far infrared emissivity is as high as 0.87, it can store heat and keep warm, and the temperature rise speed is faster than ordinary cotton fabric. Moisture control, to achieve the effect of dehumidification and drying: high balance moisture regain and water retention rate, endow bamboo charcoal fiber with the ability of moisture control. High negative ion emission concentration: generally, the negative ion concentration of urban parks is 1000-2000 cells / cm3, that of suburban fields is 5000-50000 / cm3, and that of bamboo charcoal fiber is 6800 / cm3, which is equivalent to the negative ion concentration of suburban fields, so it is beneficial to health.

　 　 modal

Modal fiber is a kind of regenerated cellulose fiber with high wet modulus. The raw material of the fiber is Zelkova schneideriana. It is made into wood pulp and then processed into fiber by special spinning process. There is no pollution in the whole production process of the fiber. Its dry strength is close to that of polyester, and its wet strength is much higher than ordinary viscose. Its luster, softness, hygroscopicity, dyeability and color fastness are all better than those of pure cotton products. The fabric made of it shows a silk luster with pleasant soft touch and drape feeling and excellent wear resistance

It is the ideal close fitting fabric and health care Clothes & Accessories Products, conducive to human physiological cycle and health.

Modal fiber can be blended and interwoven with a variety of fibers to give full play to the characteristics of each fiber to achieve better wearing effect.

1. Modal fiber fabric has soft handle, good drapability and comfortable wearing.

2. Modal fiber fabric has better moisture absorption and air permeability than pure cotton fabric. It is an ideal close fitting fabric and health care clothing product, which is conducive to human physiological cycle and health.

3. Modal fiber fabric is smooth, delicate and smooth with natural silk effect.

4. Modal fiber fabric is a natural mercerizing fabric with bright color and light quantity.

On the contrary, after washing with modal for 5 times, the fabric becomes more and more stable.

6. Modal fiber fabric has good effect, strong shape stability, natural wrinkle resistance and no iron property, which makes wearing more convenient and natural.

　　 Leica

Lycra is only a trade name of NVIDIA, a former wholly-owned subsidiary of DuPont (acquired by Koch Industries Group for $4.4 billion in 2004). Due to its dominant position in the spandex market, Lycra has become a synonym for almost all spandex yarns. It completely replaces the traditional elastic rubber cord, which has special requirements in gymnastic clothes and swimming suits clothing Lycra is almost an essential component. It allows you to be curvy and stretch freely without pressure. Lycra is not only widely used in everyday fashion designer Make a popular kaleidoscope of pets. According to DuPont's quality specification, Lycra is different from traditional elastic fiber in that it can stretch up to 500% and return to its original state. That is to say, this kind of fiber can be stretched very easily, but after recovery, it can cling to the surface of the human body, which has little binding force on the human body. Lycra fiber can be used with any fabric, including wool, hemp, silk and cotton, to increase the fabric's close fitting, elastic and natural characteristics, and feel more flexible when moving. In addition, it does not have the special structure of the polyurethane fiber in the hot water.

The length of Lycra can be recovered to 7 times of the original length. It cannot be used alone and can be interwoven with any other man-made or natural fibers. It does not change the appearance of the fabric, is an invisible fiber, can greatly improve the performance of the fabric. Lycra has outstanding stretch. For knitwear, its multidirectional extension is determined by the fabric itself. Lycra only brings elasticity after stretching and recovery.

　　 spandex

It has the name of fiber, such as nylon, nylon, etc. It has good dyeing performance and can be dyed into various kinds of fast colors. The dye has strong affinity to fiber, can adapt to most kinds of dyes, and has good chemical resistance. It is resistant to most acid and alkali, chemical agents, organic solvents, dry cleaning agents and bleaching agents, as well as sunlight and snow, but it is not resistant to oxides, which makes the fiber yellowing and strength decrease. In general, a small amount of spandex is not used alone. This kind of fiber has the properties of both rubber and fiber. Most of them are used in the core spun yarn with spandex as the core yarn, which is called elastic core spun yarn. The main characteristics of this kind of yarn are as follows: first, it can obtain good handle and appearance; second, it can produce high-quality elastic yarn with only 1-10% spandex filament; Third, the elastic percentage control range is from 10% to 20%. Different elastic values can be selected according to the use of the product.

　　 nylon

Nylon is the Chinese name of synthetic fiber nylon, the translated name is also called "nylon", "nylon", the scientific name is polyamidefibre, namely polyamide fiber. Since Jinzhou Chemical Fiber Factory is the first factory in China to synthesize polyamidefibre, it is named "nylon". It is the earliest synthetic fiber variety in the world. It has been widely used because of its excellent performance and abundant raw material resources.

Properties of nylon: strong, good wear resistance, the residence has fiber first. Its wear resistance is 10 times of cotton fiber, 10 times of dry viscose fiber and 140 times of wet state fiber. Therefore, it has excellent durability. Nylon fabric has excellent elasticity and elastic recovery, but it is easy to deform under small external force, so it is easy to wrinkle during wearing. Poor ventilation, easy to produce static electricity. The moisture absorption of nylon fabric is better in synthetic fiber fabric, so the clothing made of nylon is more comfortable than that of polyester. It has good moth resistance and corrosion resistance. The ironing temperature should be controlled below 140 ℃. In the process of wearing and using, it is necessary to pay attention to the washing and maintenance conditions to avoid damaging the fabric. Nylon fabric is a light fabric, which is only listed after polypropylene and acrylic fiber fabrics in synthetic fiber fabrics. Therefore, it is suitable for making mountaineering clothes and winter clothes.

　 Carding cotton

Combed cotton - short fibers (less than 1cm) are removed from cotton fibers by combing machine, while long and neat fibers are left. The yarn spun from combed cotton is fine and of good quality. Made of combed cotton yarn cloth In texture, washability and durability have a high level of quality. Cotton fiber has high strength, good wrinkle resistance, poor tensile property; good heat resistance, next to hemp; poor acid resistance, dilute alkali resistance at room temperature; good affinity for dyes, easy dyeing, complete chromatography, and bright color.

　　 polyester

Polyester fiber is a kind of polyester (PET, polyethylene terephthalate) as the main raw material, adding certain functional masterbatch, the product density is 136g / cm3, soluble in phenol - tetrachloroethane, o-chlorophenol and other solvents, with minimal moisture absorption, acid resistance, high chemical stability and polyamide, and has good light resistance. The fiber does not embrittle and deform at - 40 ℃ - + 250 ℃. Each fiber is independent and provides great cohesion. As textile raw materials, polyester fiber has high strength, strong wear resistance, good elasticity and strong heat resistance.

　　 Kapok

Kapok Thermal Underwear It is a kind of underwear made of kapok fiber, with various styles. There are lightweight kapok thermal underwear loved by young people, as well as cashmere kapok thermal underwear with excellent thermal effect, especially suitable for middle-aged and elderly people.

Today's natural thermal underwear is the pursuit of high-quality green underwear. Kapok thermal underwear has the characteristics of light, soft, smooth surface, bright color, antistatic and not easy to tangle. In addition, the kapok thermal underwear has strong moisture absorption and moisture transfer performance, so the user can wear it dry and comfortable. Moreover, the kapok thermal underwear can withstand acid and alkali at room temperature, and it will not become moldy or moth eaten for a long time after use.

It is understood that different from the previous cotton underwear, high-end thermal underwear is more popular this year. More than 400 yuan of kapok thermal underwear series, 300 yuan of ecological napping series have become hot goods. "Kapok thermal underwear is our sales champion this year, with an average of more than 60 sets per day, accounting for 1 / 3 of the total daily turnover." According to a underwear store manager said. It can also be seen that, with the improvement of people's living standards, consumers' consumption awareness of underwear brand is gradually enhanced. In Yiwu, known as "the ocean of small commodities in the world", various mature underwear brands, such as Longsha, Yiting, yuanfenniao, Goshman, sangun, clockwise, etc., conform to the needs of consumers and constantly introduce high-quality underwear products, which makes the brand sales advantages obvious.

Kapok fiber used in kapok thermal underwear is the thinnest, lightest, highest hollowness and the most warm fiber material among natural ecological fibers. Its fineness is only 1 / 2 of that of cotton fiber, but its hollow ratio is more than 86%, which is 2-3 times of that of general cotton fiber. It has the advantages of bright and clean, antibacterial, mothproof, mildewproof, gentle, not easy to tangle, water and heat conduction, ecology, warmth, moisture absorption and moisture transmission.

The degree of industrialization of kapok fiber used in kapok thermal underwear is not high. Most of the fabrics used in kapok thermal underwear are blended with various natural fibers (cotton, camel hair, wool, cashmere, rabbit hair, silk, hemp, etc.) and man-made fibers (nylon, acrylic, polyester, polypropylene, viscose, PTT, etc.). Kapok fabric made of 100% kapok clothes There are relatively few assembly lines.

As kapok thermal underwear is light, soft, smooth, bright, antistatic, not easy to tangle, moisture absorption and moisture transfer, not mold and moth, acid and alkali resistance at room temperature, green and natural environmental protection characteristics, favored by consumers.
