*WHAT IS “MICRO-FIBER BLEND”?
(“autofiber link”)
.
-[micro-fiber] is ‘synthetic fiber’ finer than 1 ‘denier’ or ‘decitex’/’thread’, having a ‘diameter’ of [(less than) 10 micro-meters]-
.
The most common types of microfiber are made variously of polyesters; polyamides (e.g., nylon, Kevlar, Nomex, trogamide); and combinations of polyester, polyamide, and polypropylene.
Microfiber is used to make mats, knits, and weaves, for apparel, upholstery, industrial filters, and cleaning products.
The shape, size, and combinations of synthetic fibers are chosen for specific characteristics, including softness, toughness, absorption, water repellence, electrostatics, and filtering ability
.
History
Production of ultra-fine fibers (finer than 0.7 denier) dates from the late 1950s, using melt-blown spinning and flash spinning techniques.
Initially, only fine staples of random length could be manufactured and very few applications were found.[1]
Then came experiments to produce ultra-fine fibers of a continuous filament type:
the most promising experiments were made in Japan in the 1960s, by Dr. Miyoshi Okamoto, a scientist at Toray Industries
Okamoto’s discoveries and those of Dr. Toyohiko Hikota led to many industrial applications, including Ultrasuede, one of the first successful synthetic microfibers, which entered the market in the 1970s.
Microfiber’s use in the textile industry then expanded.
Microfibers were first publicized in the early 1990s, in Sweden, and saw success as a product in Europe over the course of the decade
.
Apparel
Clothing
Microfiber fabric is frequently used for athletic wear, such as cycling jerseys, because the microfiber material wicks moisture (perspiration) away from the body;
subsequent evaporation cools the wearer.
Microfiber is also very elastic, making it suitable for undergarments.
Microfiber can be used to make tough, very soft fabric for clothing, often used in skirts and jackets.
Microfiber fabric can also be used in bathrobes, jackets, swim trunks, and other aquatic apparel.
Microfiber can be made into Ultrasuede, a synthetic imitation of suede leather, which is cheaper and easier to clean and sew than natural suede leather
.
Accessories
Microfiber is used to make many accessories that traditionally have been made from leather: wallets, handbags, backpacks, book covers, shoes, cell phone cases, and coin purses.
Microfiber fabric is lightweight, durable, and somewhat water repellent, so it makes a good substitute
Another advantage of Microfiber fabric (compared to leather) is that it can be coated with various finishes and can be treated with antibacterial chemicals.
Fabric can also be printed with various designs, embroidered with colored thread, and heat-embossed
.
Other uses
Textiles for cleaning
Cross sections: microfiber thread above, cotton thread below
Microfiber cloth for cleaning screens and lenses
Microfiber mop with ‘velcro back’ for fastening on ‘handle’
.
In cleaning products, microfiber can be 100% polyester, or a blend of polyester and polyamide (nylon).
It can be either a woven product or a non woven product, the latter most often used in limited use or disposable cloths.
In the highest-quality fabrics for cleaning applications, the fiber is split during the manufacturing process to produce multi-stranded fibers.
A cross section of the split microfiber fabric under high magnification would look like an asterisk
The split fibers and the size of the individual filaments make the cloths more effective than other fabrics for cleaning purposes.
The structure traps and retains the dirt and also absorbs liquids.
Unlike cotton, microfiber leaves no lint, the exception being some micro suede blends, where the surface is mechanically processed to produce a soft plush feel
For microfiber to be most effective as a cleaning product, especially for water-soluble soils and waxes, it should be a split microfiber.
Non-split microfiber is little more than a very soft cloth.
The main exception is for cloths used for facial cleansing and for the removal of skin oils (sebum), sunscreens, and mosquito repellents from optical surfaces such as cameras, phones and eyeglasses wherein higher-end proprietary woven, 100% polyester cloths using 2 µm filaments, will absorb these types of oils without smearing
Microfiber that is used in non-sports-related clothing, furniture, and other applications isn’t split because it isn’t designed to be absorbent, just soft.
When buying, microfiber may not be labelled to designate whether it is split.
One way to determine what microfiber it is, is to run the cloth over the palm of the hand.
A split microfiber will cling to imperfections of the skin and can be either heard or felt.
Another way is to pour a small amount of water on a hard flat surface and try to push the water with the microfiber.
If the water is pushed rather than being absorbed, it’s not split microfiber
Microfiber can be electrostatically charged for special purposes like filtration
.
Cloths and mops
Microfiber products used for consumer cleaning are generally constructed from split conjugated fibers of polyester and polyamide.
Microfiber used for commercial cleaning products also includes many products constructed of 100% polyester.
Microfiber products have exceptional ability to absorb oils, and are not hard enough to scratch even paintwork unless they have retained grit or hard particles from previous use.
Due to hydrogen bonding, microfibre cloth containing polyamide absorbs and holds more water than other types of fibres.
Microfiber is widely used by car detailers to handle tasks such as removing wax from paintwork, quick detailing, cleaning interior, cleaning glass, and drying.
Because of their fine fibers which leave no lint or dust, microfiber towels are used by car detailers and enthusiasts in a similar manner to a chamois leather
Microfiber is used in many professional cleaning applications, for example in mops and cleaning cloths.
Although microfiber mops cost more than non-microfiber mops, they may be more economical because they last longer and require less effort to use
Microfiber textiles designed for cleaning clean on a microscopic scale.
According to tests using microfiber materials to clean a surface leads to reducing the number of bacteria by 99%, whereas a conventional cleaning material reduces this number only by 33%
Microfiber cleaning tools also absorb fat and grease and their electrostatic properties give them a high dust-attracting power.
Microfiber cloths are used to clean photographic lenses as they absorb oily matter without being abrasive or leaving a residue, and are sold by major manufacturers such as Sinar, Nikon and Canon.
Small microfiber cleaning cloths are commonly sold for cleaning computer screens and eyeglasses.
Microfiber is unsuitable for some cleaning applications as it accumulates dust, debris, and particles.
Sensitive surfaces (such as all high-tech coated surfaces e.g. CRT, LCD and plasma screens) can easily be damaged by a microfiber cloth if it has picked up grit or other abrasive particles during use.
One way to minimize the risk of damage to flat surfaces is to use a flat, non-rugged microfiber cloth, as these tend to be less prone to retaining grit.
Rags made of microfiber must only be washed with regular laundry detergent, not oily, self-softening, soap-based detergents.
Fabric softener must not be used.
The oils and cationic surfactants in the softener and self-softening detergents will clog up the fibers and make them less absorbent until the oils are washed out.
Also, since microfibre cloth attracts much soil and holds water tightly, it provides an ideal nutritional environment for various micro-organisms
.
Insulation
Microfiber materials such as PrimaLoft are used for thermal insulation as a replacement for down feather insulation in sleeping bags and outdoor equipment, because of their better retention of heat when damp or wet
Microfiber is also used for water insulation in automotive car covers.
Depending on the technology the fiber manufacturer is using, such material may contain from 2 up to 5 thin layers, merged.
Such combination ensures not only high absorption factor, but also breathability of the material, which prevents ‘greenhouse effect’
.
basketballs
With microfiber-shelled basketballs already used by FIBA, the NBA introduced a microfiber ball for the 2006–07 season.[10]
The ball, which is manufactured by Spalding, does not require a “break-in” period of use as leather balls do and has the ability to absorb water and oils, meaning that sweat from players touching the ball is better absorbed, making the ball less slippery
Over the course of the season, the league received many complaints from players who found that the ball bounced differently from leather balls, and that it left cuts on their hands
On January 1, 2007, the league scrapped the use of all microfiber balls and returned to leather basketballs
.
Other
Microfibers used in tablecloths, furniture, and car interiors are designed to repel wetting and consequently are difficult to stain.
Microfiber tablecloths will bead liquids until they are removed and are sometimes advertised showing red wine on a white tablecloth that wipes clean with a paper towel.
This and the ability to mimic suede economically are common selling points for microfiber upholstery fabrics
(e.g., for couches)
.
Microfibers are used in towels especially those to be used at swimming pools as even a small towel dries the body quickly.
They dry quickly and are less prone than cotton towels to become stale if not dried immediately.
Microfiber towels need to be soaked in water and pressed before use, as they would otherwise repel water as microfiber tablecloths do
.
Microfiber is also used for other applications such as making…
menstrual pads,
cloth diaper inserts,
body scrubbers,
face mitts,
whiteboard cleaners,
and various goods that need to absorb water and/or attract small particle
.
Environmental and safety issues
Microfiber textiles tend to be flammable if manufactured from hydrocarbons (polyester) or carbohydrates (cellulose) and emit toxic gases when burning,
more so if aromatic (PET, PS, ABS) or treated with halogenated flame retardants and azo dyes.[12]
Their polyester and nylon stock are made from petrochemicals, which are not a renewable resource and are not biodegradable.
For most cleaning applications they are designed for repeated use rather than being discarded after use
An exception to this is the precise cleaning of optical components where a wet cloth is drawn once across the object and must not be used again as the debris collected are now embedded in the cloth and may scratch the optical surface.
Microfiber products may also have the potential of entering the oceanic water supply and food chain similar to other microplastics
Synthetic clothing made of microfibers that are washed release materials and travel to local wastewater treatment plants, contributing to plastic pollution in water.
Fibers retained in wastewater treatment sludge (biosolids) that are land-applied can persist in soils
There are environmental concerns about this product entering the oceanic food chain similar to other microplastics
A study by the clothing brand Patagonia and University of California, Santa Barbara, found that when synthetic jackets made of microfibers are washed, on average 1.7 grams (0.060 oz) of microfibers are released from the washing machine.
These microfibers then travel to local wastewater treatment plants, where up to 40% of them enter into rivers, lakes, and oceans where they contribute to the overall ‘plastic pollution’
(talk about “splitting hairs!”)
.
Microfibers account for 85% of man-made debris found on shorelines worldwide

What is Microfiber Blend? What does 80/20, 75/25 and 70/30 mean?
3-3 minutes
The blend of a microfiber towel is the ratio of the components that make up the fibers of the fabric.
Most microfiber is a blend of polyester and polyamide.
Some (lower quality) microfiber is 100% polyester (there is some high grade 100% polyester microfiber, which does perform wel, in certain applications).
The first number represents the ratio of polyester and the second number the ratio of polyamide.
In general, polyester is the scrubbing and cleaning component, and the polyamide is the absorbent component of the fiber.
Polyester is the dominant material in all microfiber products.
Polyamide is more expensive than polyester, so all else being equal, fabrics with a more of it, are more expensive.
With high quality fabrics made on the same weaving or knitting machine, a 70/30 material will be softer and more absorbent than an 80/20 material.
With some soft automotive paint, detailing professionals, using high grade lighting, can see the micro scratches left by some 80/20 towels, where the same towel in 70/30 leaves no marks behind.
With all of that said, most microfiber material is marked incorrectly (either on purpose, by supplier, without their knowledge, or because of factory cost cutting).
The only reason that the microfiber blend is marked on the towels (usually with a sewn in tag) is that US Customs requires that all textiles imported be marked with their components/ingredients, and their country of origin.
There is no one, or authority out there checking to make sure that fabrics are marked correctly.
It is up to the seller to check this on their own.
This expensive lab test can be cost prohibitive.
Factories will cut corners to meet price points, and in order to do so will use less expensive materials but leave the marked specifications unchanged.
We have done independent tests on one big box stores popular microfiber towels and they were 100% polyester (or 95/5), when marked 80/20.
We also have competitors who we know buy from our same factory in South Korea but mark their towels as 70/30 when they are really made from 80/20 material.
So what should you do as a consumer trying to select the right microfiber towels for your business or hobby?
Only buy from reputable sources, who have consistent production, and quality control.
Make sure you evaluate new towels, to ensure that they meet your standards.
The advertised (and marked) microfiber blend of the towel should not influence your evaluation of the products.
always use your own best judgement!
