Application of Microfiber:
Microfiber is a fairly new technology, with many applications in many industries. Cleaning with microfiber products is fast, easy and environmentally friendly. With microfiber products you can eliminate or drastically reduce the need to use chemicals. Microfiber cleaning fabrics are sometimes described as having a magnetic attraction to dirt and dust. Microfiber products are extremely soft and do not scratch, but at the same time they are effective for all cleaning applications.

Fashion clothing textiles
Woven fabric was produced from even a 0.1 dtex UFF hollow microfibre combined with a single hollow staple fibre. This product offers softness, bulk, dry handle, a sense of warmth, good recovery, and is lightweight.

High-performance filter fabrics
Owing to their fine, compact structure, microfibre textiles offer excellent filtration effects for both air and fluid filtration. Independently on common microfibres, also ultra-fine microfibre products, such as0.05 dtex PP microfibre nonwovens, in combination with a high electrical voltage, which will provide permanent polarization to the nonwoven, attract and absorb charged dust particles. Microfibre textiles can produce excellent filtration effects in the process of filtering solid or liquid materials. The characteristics of microfibre liquid filters are as follows:
  • High water passage speed,
  • High extraction performance (retention of particles up to micrometers dimensions), and
  • Ease of cleaning micro-particles from the filter.
The micrometer-sized fibre segments add mechanical filtration properties to the filter medium. Also, two different dissimilar polymers can be selected that will generate turboelectric properties under flow conditions. The two polymers may also be electrostatically chargeable to enhance first-step filtration properties. These filtration mechanisms, when combined properly, may be able to create a higher efficiency, lower pressures drop-filter materials that will last longer before plugging in both air and liquid applications.

Protection against the weather
Woven sportswear fabrics are also used for protection against wind and weather, and also for insulation purposes. Woven fabrics for protection against the weather were previously coated with polyvinyl chloride (PVC) in most cases. The PVC coating guarantees absolute waterproofness, but has a serious disadvantage. It allows no passage of air; the wearer perspires after only a few minutes, and has no opportunity of expelling his body moisture to the outside of the garment. This coating is equivalent to an airproof package, and is used nowadays only for heavy duty rainproof clothing (the so-called oil-cloth).Today, there is a wealth of alternative coatings and methods to replace PVC, such as microporousfluorocarbon coatings, which guarantee some breathing activity on the part of the fabric. Thanks to ever finer yarns, fabrics can now be produced to meet practically all functional sportswear requirements without additional coating or membranes. They are wind- and water-repellent, yet can breathe.

Microfibres for cleaning
Microfibre products are suitable for cleaning anything. Unlike ordinary cleaning fabrics that move or push dirt and dust from one place to another, microfibres actually ‘scrape’ the dirt or stain from the surface, and then store the dirt particles in the fabric until it is washed. Microfibre cleaning clothes trap dirt and dust inside the cloth, and do not spread dust or dirt around. The user can clean the cloths with water alone; no chemicals are needed. The scheme of cleaning dirt by common fibres and microfibres are shown in below.

Works of micro fibre
Energy conservation
Experiments have shown the drastic savings in the energy consumption in heat exchanges which are brought about by using metal-coated microfibres. In this case, the microfibre shows its heat conveying properties. By using the metal-coated microfibres inside the tubes of heat exchangers, heat transfer enhancement can be achieved. The findings of the above experiments are as follows:
  • Heat transfer increases with the number of metal-coated microfibres.
  • Pressure drops increase with the number of microfibres.
Medical applications
When it comes to the medical market, microfibre nonwovens are exactly what the doctor ordered. Both manufacturers and consumers are already aware of the many benefits microfibre nonwovens offer to the medical market. When compared the commonly textiles to microfibre nonwovens, they are lower in cost, easier to use, more versatile, safer, and features of better disposability. With this in mind, it is no wonder that microfibre nonwovens are found in hospital surgical drapes and gowns, protective face masks, gloves, surgical packs, and bedding & linens. On the other hand, nanofibres help stimulate living tissues to repair themselves in various parts of the human body, such as cartilage, blood vessels, bones and so forth, due to diseases or wear and tear.Nanofibres are about 10,000 times smaller in diameter than the width of a human hair, but of greater dimensions than a typical cell, which is of the order of one micrometer depending of the type of cell.Nanofibres have a large surface area in comparison to their size. Smaller than usual fibres, they allow cells to adhere to them better, speeding up the healing process.

Microfiber is widely used in case of;
  1. Apparel
  2. Clothing
  3. Accessories
  4. Textiles for cleaning
  5. Rags
  6. Insulation
  7. Basketballs
  8. Environmental issues
