wool
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 excellent stretchability and elastic recovery, special scale structure and excellent flexibility, so it also has good appearance retention. At present, the processing procedure of thermal underwear wool is very mature, and it will not deform or shrink when worn.
bamboo charcoal
Known as the "black diamond", it is internationally known as the "2 1 century new environmental guardian". 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.
The main performance of bamboo charcoal fiber is its super adsorption capacity: the adsorption capacity of bamboo charcoal is more than 5 times that of charcoal, and it can adsorb, decompose and deodorize harmful substances and dust such as formaldehyde, benzene, toluene and ammonia. For example, the ammonia removal rate of ordinary viscose fiber is only 17.4%, while the ammonia removal rate of bamboo charcoal viscose fiber reaches 54%. Emit far infrared rays, store heat and keep warm: the emissivity of far infrared rays is as high as 0.87, which can store heat and keep warm, and the heating rate is faster than that of ordinary cotton fabrics. Humidity control, dehumidification and drying: high equilibrium moisture regain and water retention rate give bamboo charcoal fiber humidity control ability. The emission concentration of negative ions is high: in general, the concentration of negative ions in urban parks is1000-2,000 /cm3, that in suburban fields is 5,000-50,000 /cm3, and that of bamboo charcoal fibers is 6,800 /cm3, which is equivalent to that in suburban fields and is beneficial to health.
Modal
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 has silky luster, comfortable soft touch and drape, and excellent durability.
It is an ideal close-fitting fabric and health care clothing product, which is beneficial to human physiological cycle and health.
Application of Modal Yarn Modal fiber can be blended and interwoven with various fibers to give full play to the characteristics of each fiber and achieve better wearing effect.
1, modal fiber fabric, soft to the touch, good drape and comfortable to wear.
2. Modal fiber fabric is superior to pure cotton fabric in moisture absorption and breathability, and it is an ideal close-fitting fabric and healthy clothing product, which is beneficial to human physiological cycle and health.
3. Modal fiber fabric feels smooth, delicate and smooth, and has the effect of natural silk.
4. Modal fiber fabric is a natural mercerized fabric with bright color and light weight.
5. Modal fiber fabric has stable wearability. After testing and comparison, cotton fabric will feel harder and harder after washing for 25 times, while modal fiber fabric is just the opposite, softer and brighter after washing.
6. Modal fiber fabric has good effect, strong morphological stability, natural wrinkle-resistant and non-ironing, and is more convenient and natural to wear.
Lycra
Lycra is just a trade name of Invista, a former wholly-owned subsidiary of DuPont (acquired by Koch Industrial Group for $4.4 billion in 2004). Due to its monopoly 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.
Lycra can stretch freely for 4-7 times, and after the external force is released, it will quickly return to its original length. It cannot be used alone, but it can be interwoven with any other man-made or natural fiber. It does not change the appearance of the fabric, and it is an invisible fiber, which can greatly improve the performance of the fabric. Lycra has outstanding ductility. For knitwear, its multidirectional extension is determined by the fabric itself, and Lycra only brings elasticity after stretching.
spandex fiber
Spandex fiber is the abbreviation of polyurethane fiber, and its trade names are Lycra (USA, UK, Netherlands, Canada, Brazil), Neolon (Nylon, Japan), Dorlastan, Germany, etc. It has excellent dyeing performance, can be dyed in various shades, has strong affinity for fibers, can adapt to most kinds of dyes, has good chemical resistance, is resistant to most acids, alkalis, chemicals, organic solvents, dry cleaners and bleaches, is resistant to sun and snow, but is not resistant to oxides, and is easy to make fibers yellow and reduce strength. Generally, spandex is not used alone, but a small amount is mixed into the fabric. This kind of fiber has both rubber properties and fiber properties, and is often used in core-spun yarn with spandex as the core, which is called elastic core-spun yarn. The main characteristics of this kind of yarn are: first, it can obtain good hand feel and appearance, and the outer fiber is composed of natural fiber, which has good hygroscopicity; Second, only 1- 10% spandex filament can produce high-quality elastic yarn; Thirdly, the control range of elasticity percentage is from 10% to 20%, and different elasticity values can be selected according to the use of the product.
nylon
Nylon is the Chinese name of synthetic fiber nylon, which is also translated as "nylon" and "nylon". The scientific name is polyamide fiber, that is, polyamide fiber. Jinzhou Chemical Fiber Factory is the first factory in China to synthesize polyamide fiber, hence the name "nylon". It is the earliest synthetic fiber variety in the world, and is widely used because of its excellent performance and rich raw material resources.
Performance of nylon: good strength and wear resistance, ranking first among all fibers. Its wear resistance is 10 times of cotton fiber, 10 times of dry viscose fiber and 140 times of wet fiber. Therefore, its durability is very good. Nylon fabric has excellent elasticity and elastic recovery, but it is easy to deform under a small external force, so its fabric is easy to wrinkle during wearing. Poor ventilation and permeability, easy to generate static electricity. The hygroscopicity of nylon fabric is a good variety in synthetic fiber fabric, so the clothing made of nylon is more comfortable than polyester clothing. It has good moth resistance and corrosion resistance. The heat resistance and light resistance are not good enough, and the ironing temperature should be controlled below 140℃. Pay attention to the washing and maintenance conditions during wearing and using, so as not to damage the fabric. Nylon fabric is a kind of light fabric, which is second only to polypropylene and acrylic fabrics in synthetic fiber fabrics, and is suitable for making mountaineering clothes and winter clothes.
Cotton combing
Combed cotton-The shorter fibers (below about 1CM) in cotton fibers are removed by combing machine, while the longer and tidy fibers are left behind. Combed cotton yarn is fine and of good quality. Cloth made of combed cotton yarn has a high quality level in texture, washability and durability. Cotton fiber has high strength, good wrinkle resistance and poor extensibility; Good heat resistance, second only to hemp; Poor acid resistance, dilute alkali resistance at room temperature; Good affinity for dyes, easy dyeing, complete chromatography and bright color.
polyester fiber
Polyester fiber is made of polyester (PET) as the main raw material and some functional masterbatch. The density of the product is 136g/cm3, and it can be dissolved in solvents such as phenol-tetrachloroethane and o-chlorophenol. It has very low hygroscopicity, acid resistance, high chemical stability and good light resistance. The fibers are not brittle and deformed at the temperature of -40℃-+250℃, and each fiber independently provides great cohesion. As a textile raw material, polyester fiber has high strength, strong wear resistance, good elasticity and strong heat resistance.
kapok
Kapok thermal underwear is an underwear product made of kapok fiber, which has various styles, ranging from lightweight kapok thermal underwear popular among young people to cashmere kapok thermal underwear with excellent thermal insulation 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.
It is understood that different from ordinary cotton underwear, high-end thermal underwear is more popular this year. More than 400 yuan of kapok thermal underwear series and 300 yuan's ecological napping series have all become hot items. "Kapok thermal underwear is our sales champion this year, with an average of more than 60 sets sold every day, accounting for 1/3 of the total daily business." According to the manager of an underwear counter. It can also be seen that with the improvement of people's living standards, consumers' awareness of underwear brands is gradually improving. In Yiwu, known as the "Ocean of Small Commodities in the World", all mature underwear brands, such as Langsha, Yiting, Destiny Bird, Gershman, Top Three, Clockwise, etc. , are constantly introducing high-quality underwear products to meet the needs of consumers, which makes the brand sales advantage obvious.
The kapok fiber used in kapok thermal underwear is the thinnest, lightest, hollowest and warmest fiber material among natural ecological fibers. Its fineness is only 1/2 of cotton fiber, but its porosity is as high as 86%, which is 2-3 times that of ordinary cotton fiber. Smooth, antibacterial, moth-proof, mildew-proof, mild, not easy to wind, waterproof, non-thermal, ecological, warm, moisture-absorbing and moisture-conducting.
The industrialization of kapok fiber for kapok thermal underwear is not high. The fabrics used in kapok thermal underwear are mostly blended with various natural fibers (cotton, camel hair, wool, cashmere, rabbit hair, silk, hemp, etc.). ) and man-made fibers (nylon, acrylic, polyester, polypropylene, various viscose, PTT, etc. ). 100% kapok thermal underwear series is less.
Kapok thermal underwear is favored by consumers because of its light weight, softness, smoothness, bright color, antistatic, non-entanglement, moisture absorption, mildew and moth resistance, acid and alkali resistance at room temperature, environmental protection and other advantages.
