Mankind's first synthetic fiber, Nylon, is fiber manufactured by composing Polymer, which is most similar to mineral of silk. It was developed by Dr.Carothers at American Dupont in 1935, and commercialized from 1938. As the age of considering 'synthetic fiber is well sold when manufactured as substitute of natural fiber' is over, synthetic fiber has maximized its feature and characteristic in nowadays and it is called as highly functional and performing new materials. As clothe customers demand highly sensible and high quality products, features of high-tech fabrics are being more important. In nowadays, 'micro fiber' has brought up as a part of fulfilling customers' demands for new material and new synthetic materials in synthetic fiber industry. As all foreign synthetic fiber makers recently focus on development of micro fiber and textiles using micro fiber, it is being focused as the best promising item in synthetic fiber industry.

Definition of Micro fiber is generally determined by standard of yarn and manufacturing methods.
If we take a look at the definition of yarn standards, unit for synthetic fibers and linen is Denier and Tex. Denier is a unit representing thickness of linen, such as yarn, nylon and others, and it is calculated with the weight of yarn. 1 Denier means 1gr for 9,000m. As Denier value gets lower, the thickness gets thinner, and as the value gets higher, the thickness gets thicker.
Therefore, it requires higher technology to manufacture yarns with low Denier value. Thread of synthetic fiber gets extremely difficult as Denier value gets lower. Making some thick objects into thin objects is easy, but making a thin object with thickness of hair even thinner is extremely tough process. Therefore, securing highly reliable production technology enabling the first thing is the technology of manufacturing micro fiber, the second thing is the technology of processing micro fiber, and the third thing is the technology of making defect zero at same time is required. With hard efforts in long period, products manufactured during research and development period are produced and sold in the market. These products are new silk-like products such as Nylon and Polyester with excellent fabrics touch feeling. Like this, micro fibers or products made with micro fibers with lower than 1 Denier, which is the unit used for micro fibers are known as 'Micro fiber'.

For preventing allergic diseases and Atrophic Dermatitis, using products preventing factor materials causing allergy is most efficient. - Originally Keeps House Dust Mite Away.

Mono Filament 0.12 Denier - It has 1/100 thickness of hair and length to moon with 5g. Since it is thinner than house dust mite, house dust mite can't go through it. This is well preferred as functional fabrics for bedclothes, carpet, sofa and cloth. The characteristic of mono filament is that since it great amount of sweat, water and moisture with capillary effect, it is widely used for sports towel, sports wear and water purifier filter, and very suitable for baby item, baby clothe and underwear. Moreover, since it can even be used for artificial sweater, artificial shimmy, artificial mustang, cleaner, glass cleaner and other various purposes, it is being focused as the next generation new material in 21C.
Yarn - There are divided micro fiber, chart micro fiber, and eluted micro fiber.
