Microfiber fabric is a textile made from extremely fine synthetic fibers or filaments. In textile standards, the word generally refers to fineness rather than one fixed polymer, knit, weave, GSM, stretch level or finish. Polyester and polyamide (nylon) are common choices, but a buyer still needs the exact fiber content and construction on the technical sheet. AATCC describes microfiber as less than 1 denier and greater than 0.3 denier, while other textile references use a less-than-1-dtex threshold, so the convention should be stated when it matters.
For an apparel buyer, the useful question is not only “what is microfiber fabric?” It is: which fiber, yarn, construction and finish will deliver the hand, coverage, recovery, moisture behavior and care performance required by this garment? This guide turns the name into a quote-ready specification for activewear, swimwear, underwear, linings and other private-label apparel programs.
What Is Microfiber Fabric?
Microfiber fabric is made with very fine fibers or filaments that are assembled into a woven, knitted or nonwoven textile. The fine scale can create a smooth surface, dense coverage, soft hand and a high surface-area yarn, but those results are produced by the combination of fiber, yarn, construction, finishing and fabric weight. The name by itself is not a performance test.
The terminology needs care. AATCC’s textile explanation uses a less-than-1-denier and greater-than-0.3-denier definition, while Textile Exchange’s glossary describes a synthetic fiber finer than one denier per filament. These definitions are close in practical sourcing conversations but are not a substitute for the supplier’s stated filament or yarn specification.
| Buyer field | What it describes | Why it matters |
|---|---|---|
| Fiber content | Polymer or blend, such as polyester, polyamide or elastane | Changes dye route, recovery, care, labeling and cost |
| Fiber or filament fineness | Denier or dtex at the agreed measurement level | Separates a true microfiber yarn from a generic soft synthetic claim |
| Construction | Knit, weave, interlock, tricot, jersey, woven or other structure | Controls stretch, cover, stability, drape and seam behavior |
| Finished GSM | Fabric mass per square meter after finishing | Helps control opacity, seasonality, hand and yield |
| Stretch and recovery | Direction, extension, recovery and growth under an agreed method | Prevents a fitted garment from feeling restrictive or losing shape |
| Finish and face | Peached, brushed, wicking, sueded, coated, embossed or untreated surface | Changes touch, friction, moisture behavior and appearance |
| Usable width | Finished width available for cutting | Affects marker efficiency, consumption and quotation |
| Lot and color control | Dye lot, shade, tolerance and approval swatch | Protects repeat-order consistency and shade matching |
The buyer should therefore treat microfiber as a starting material description. The approved swatch, construction record and test evidence are the real reference for sampling and bulk production.
Is Microfiber Always Polyester or Nylon?
No. Polyester and polyamide are common because both can be engineered into very fine filaments, but microfiber is not a synonym for polyester. A microfiber fabric may be polyester, nylon, a polyester-nylon blend, or a blend that includes elastane for stretch. The polymer changes how the material behaves; the construction and finish change it again.
Polyester microfiber is often selected when dimensional stability, color development, quick-drying behavior or cost control are important. Nylon microfiber may be chosen when a buyer wants a different hand, dye response or resilience profile. Neither sentence is a universal guarantee. The actual yarn, fabric construction, finish and garment design must be approved together.
| Material description | What the name tells you | What still needs confirmation |
|---|---|---|
| Microfiber | The fiber or filament is very fine under the stated convention | Polymer, construction, GSM, width, finish and tests |
| Polyester microfiber | Polyester is used in a fine-fiber form | Filament fineness, knit or weave, dye route, recovery and care |
| Nylon or polyamide microfiber | Polyamide is used in a fine-fiber form | Grade, construction, colorfastness, recovery and abrasion behavior |
| Microfiber with elastane | Fine fiber is combined with an elastic component | Fiber percentages, stretch direction, recovery, growth and sectional labeling |
For products sold in the United States, the FTC Textile Fiber Rule requires covered textile products to disclose generic fiber names and percentages by weight. If a garment uses elastic material and another fabric, 16 CFR 303.10 is a useful reminder to confirm how the content should be documented. Do not place “microfiber” on a buyer-facing label as if it replaces the generic fiber name.
Microfiber Fabric vs Polyester, Nylon and Regular Synthetic Fabric
Polyester and nylon describe fiber chemistry. Microfiber describes a fine fiber or filament format. A regular polyester fabric may use coarser filaments, a different yarn construction or a different surface finish. A nylon microfiber fabric may feel quite different from a polyester microfiber fabric even when the two have similar GSM. The word microfiber narrows the material conversation, but it does not finish it.
For a tech pack, use the chemical name and the construction name together. For example, a brief may say “polyamide microfiber tricot with controlled two-way stretch” or “polyester microfiber interlock with a smooth face and moisture-management finish” if those are the intended requirements. The supplier should confirm whether the requested wording matches the production construction.
Do not compare fabrics only by softness. A surface can feel soft but have poor recovery, low coverage, snag risk, or unstable dimensions after washing. Compare the approved swatches under the same light, pressure, wash route and garment pattern.
Is Microfiber Fabric Stretchy?
Microfiber fabric is not automatically stretchy. Stretch comes from the fabric structure, elastane or other elastic component, yarn design, finishing and the direction in which the fabric is tested. A woven microfiber lining may have little give. A knitted microfiber fabric may have significant crosswise or four-way movement. Two fabrics carrying the same microfiber name can therefore produce very different fits.
Ask for a stretch and recovery record that describes the method, specimen direction, extension, hold time, release time and conditioning. If the material will be used for leggings, sports bras or close-fitting tops, test the garment as well as the flat fabric because seams, panels and grain direction change the result.
| Stretch or recovery field | What to record | Buyer decision |
|---|---|---|
| Direction | Lengthwise, crosswise or both directions | Confirms whether the material suits the pattern and movement |
| Extension | Percentage or distance at the agreed load and gauge length | Shows the available movement without guessing from hand feel |
| Recovery | Shape return after a stated rest period | Indicates whether the garment can stay close to the body |
| Growth or bagging | Permanent change after repeated extension or wear simulation | Flags sagging risk at knees, seat, elbows or straps |
| Seam and garment check | Fit, seam torque, coverage and comfort on the actual prototype | Confirms that the fabric works in the product, not just in a swatch |
State the intended fit and movement before asking for a sample. “Stretchy microfiber” is not a complete material brief.
Microfiber Fabric GSM, Denier, Width and Usable Yield
GSM means grams per square meter. It is a finished-fabric weight, not a synonym for filament fineness. A very fine filament can be knitted into a light lining, a compact interlock or a denser performance fabric. The construction, loop or yarn density, finishing and width determine the finished GSM.
Denier or dtex may describe the fiber, filament, yarn or a yarn bundle, so the level of measurement must be written down. A buyer can ask whether the supplier is reporting denier per filament, total yarn denier or another count. This prevents two suppliers from appearing to quote the same “microfiber” specification when they are not describing the same thing.
Usable width is the width available after finishing, selvage and any unusable edge are excluded. It matters to consumption, marker planning and cost. Record open width or tubular width, finished GSM tolerance, roll length, edge condition and whether the fabric relaxes before cutting.
Do not publish a universal microfiber GSM range. Instead, give the garment type, coverage target, climate, construction, stretch requirement and target finished weight. The supplier can then propose a sample that can be measured and compared.
How Surface Fineness Changes Hand Feel and Coverage
Fine fibers can create a smooth hand and a dense-looking surface because more filaments can be present within a yarn or fabric area. The result may be soft, fluid, compact or subtly lustrous. A split filament, brushing, peaching, sueding, calendaring or coating can change the surface again. The same fiber family can therefore support a smooth lining, a matte activewear face or a soft fashion finish.
Coverage is not guaranteed by the microfiber label. It depends on GSM, construction, color, stretch state, light transmission, finishing and the garment’s ease. Test the fabric in the intended color and at the intended stretch. For a light color or a close-fitting product, inspect coverage both flat and worn over the approved base layer.
Is Microfiber Fabric Breathable and Moisture-Wicking?
Microfiber can be used in moisture-management garments, but breathability and wicking are construction and test questions, not automatic properties of the name. Air permeability, thickness, cover factor, yarn geometry, surface finish, knit openness and garment panels all affect comfort. A dense surface may feel smooth and protective but behave differently from an open knit.
For a performance brief, separate liquid moisture movement from water-vapor or air movement. Ask for the agreed liquid moisture-management, wicking, drying or air-permeability method where that performance matters. AATCC’s standards list includes TM195 for liquid moisture management, TM197 and TM198 for wicking, TM199 through TM201 for drying behavior and TM204 for water vapor transmission.
The practical approval route is to test the fabric and wear the finished prototype. The same fabric can feel comfortable in a loose training top and too warm in a tightly lined compression panel because the garment architecture is different.
What Is Microfiber Fabric Used For in Apparel?
Microfiber fabric is used for activewear, training tops, leggings, swimwear, underwear, slips, linings, lightweight jackets and fashion garments that need a smooth surface or controlled drape. It can also appear in accessories and cleaning textiles. The cleaning-cloth meaning is common in consumer search, but it should not be allowed to blur an apparel specification.
For activewear, a buyer may value a smooth low-friction face, quick-drying behavior, controlled stretch, coverage and a clean print surface. For swimwear or underwear, recovery, opacity, chlorine or perspiration colorfastness and skin comfort may carry more weight. For a lining, low bulk, usable width, static behavior, snag resistance and sewing performance may matter more than high stretch.
Match the fabric to the product’s failure points. A fabric that looks excellent as a swatch may not be the right choice for a high-friction gusset, a compression waistband or a heat-exposed care route.
Care, Pilling, Snagging and Dimensional Change
Care instructions should be based on the actual fiber blend, finish and garment test. Heat, aggressive agitation, rough surfaces and unsuitable chemicals can change the surface, recovery, color or dimensions. Fine filaments can also make a fabric feel smooth while remaining sensitive to a sharp snag, rough hook-and-loop or high-friction seam.
Pilling is not a guaranteed microfiber advantage or disadvantage. It depends on fiber length, yarn twist, surface hairiness, finishing, abrasion and laundering. Inspect both the face and reverse, especially where a backpack, seat, thigh, underarm or equipment contact will create repeated friction. Record the agreed method and rating rather than using an unqualified “anti-pilling” claim.
Dimensional change should be checked in the intended care route. AATCC TM135 is one named method for dimensional changes of fabrics after home laundering, but the final method and acceptance criteria should match the product, market and buyer agreement. Include length, width, skew, spirality and garment measurements where relevant.
How to Specify Microfiber Fabric in a Tech Pack
A quote-ready microfiber brief separates facts you already know from properties that need supplier confirmation. Include a reference swatch or image where possible, but do not let a moodboard replace measurable fields. The sample should be traceable to a construction record and an approved color or lab dip.
| Tech-pack field | Example of a useful instruction | Evidence to request |
|---|---|---|
| Product and end use | Training top, swim short, lining or underwear | Pattern, reference garment or use description |
| Fiber content | Exact percentages and generic fiber names | Technical sheet and label wording review |
| Yarn or filament | Microfiber convention, denier or dtex level | Yarn or fabric specification |
| Construction | Knit or woven type, gauge or structure if known | Swatch, construction note and width record |
| Finished GSM and tolerance | Target weight after finishing with an agreed tolerance | Measured sample and lot report |
| Usable width | Open or tubular finished width excluding unusable edges | Roll inspection record |
| Stretch and recovery | Direction, extension, recovery, growth and method | Test result plus garment fit review |
| Surface and finish | Smooth, peached, brushed, wicking, coated or untreated | Approved hand-feel and finish swatch |
| Color and care | Pantone or lab dip route, wash and heat limits | Lab dip, colorfastness and care review |
| Test plan | Moisture, dimensional change, pilling, abrasion or coverage as needed | Pre-bulk test report and retained sample |
When a requirement is unknown, write “to be confirmed after sample review” rather than inventing a number. A supplier can help convert the garment goal into a practical construction, but the approved standard should be captured before bulk.
For help organizing the material and garment brief, see the fabric and trim library, tech pack customization service and sampling and prototyping workflow. Send the target use, swatch, drawing or tech pack so the material recommendation is tied to a real product.
What to Test Before Bulk Approval
The test plan should reflect the garment’s risks and the claims used in the product listing. A basic fabric identity and measurement check may be enough for a simple lining, while a close-fitting performance garment may need moisture, stretch, recovery, coverage, laundering and abrasion evidence. The buyer and supplier should agree the specimen conditioning, method, tolerance and decision rule before testing.
| Pre-bulk check | Evidence | Decision it supports |
|---|---|---|
| Fiber content and construction | Technical sheet, swatch and composition review | Confirms the supplied material matches the brief |
| GSM, width and thickness | Measured lot sample with tolerance | Confirms yield, coverage and cutting assumptions |
| Stretch, recovery and growth | Flat-fabric result plus garment fit observation | Confirms mobility and shape retention |
| Moisture, wicking and drying | Agreed lab method or comparative wear evidence | Supports a performance statement without overclaiming |
| Dimensional change | Wash or care-route measurement | Confirms pattern and care stability |
| Pilling, abrasion and snag risk | Agreed rating, rub or inspection evidence | Checks high-contact areas and surface life |
| Colorfastness and shade | Lab dip, approved standard and wash or perspiration check | Protects color consistency and care instructions |
| Final garment review | Retained sample, measurement chart and approval notes | Connects the fabric result to the sewn product |
The AATCC standards catalog provides named methods for dimensional change, abrasion, colorfastness, moisture management, wicking, drying and fiber-fragment release. The correct method depends on the product and market; listing a test name is not the same as passing it. Keep the approved swatch, report and sample comments together for repeat orders.
A Practical Microfiber Fabric Sampling Workflow
- Write the garment brief. State the product, fit, climate, movement, coverage, surface and care expectations.
- Define the material. Record the preferred polymer or blend, microfiber convention, construction, finished GSM, usable width and finish.
- Request comparable options. Ask for a swatch card or small cut sample with composition, width, weight and available colors.
- Test the risk points. Measure the flat fabric and build the intended prototype so stretch, recovery, coverage, sewing and comfort can be reviewed together.
- Approve the standard. Record the selected swatch, color, measurements, tolerance, care route, test evidence and revision comments.
- Protect the bulk reference. Retain the approved sample and connect it to the purchase order, inspection plan and packing instructions.
The workflow keeps a material name from becoming a vague promise. It also gives a buyer a clear point to change the construction before the pattern, decoration and bulk plan are locked.
Common Microfiber-Fabric Sourcing Mistakes
- Treating microfiber as a fixed fiber instead of confirming polyester, nylon, elastane or another blend.
- Asking for “soft and stretchy” without specifying construction, direction, extension, recovery and growth.
- Comparing GSM values that were measured before and after different finishing or relaxation conditions.
- Approving a dark swatch and assuming a light color will have the same coverage and shade behavior.
- Using a cleaning-cloth specification for an apparel product without checking hand, skin comfort, sewing and care.
- Publishing wicking, quick-dry, anti-pilling or breathable claims before the actual fabric or garment is tested.
- Sending a sample to bulk without keeping the approved swatch, measurement record and comment history.
Frequently Asked Questions
Microfiber fabric is made from very fine synthetic fibers or filaments. Polyester and polyamide (nylon) are common, and blends may include elastane or other fibers. Confirm the exact fiber percentages on the technical sheet or label because microfiber describes fineness, not one fixed chemistry.
No. Polyester is common, but polyamide (nylon) and blends are also used. The fiber content, yarn construction, finish and end use should be confirmed for each fabric lot.
Not automatically. Stretch comes from knit construction, elastane, yarn design and finishing. Request stretch direction, extension, recovery and growth results instead of relying on the microfiber name.
Breathability depends on construction, thickness, cover factor, finish and garment design. A microfiber label alone cannot guarantee air permeability or moisture comfort; request the relevant test or a wear-trial sample.
There is no universal microfiber GSM. Finished weight depends on construction and end use. State the target finished GSM and tolerance, then verify the approved lot after finishing.
It can be suitable when the construction, stretch and recovery, moisture management, coverage, colorfastness and care performance match the garment. Approve the fabric through a sample and test plan, not the name alone.
Pilling depends on fiber, yarn, surface, finish, friction and laundering. Some microfiber surfaces resist pilling while others can fuzz or snag. Use an agreed pilling or abrasion method and inspect the actual garment.
Send the garment type, target use, composition preference, construction, GSM and tolerance, usable width, stretch and recovery needs, finish, color, quantity, care route, packaging and any test or labeling requirements. A moodboard, reference swatch or tech pack speeds the review.
How to Choose Microfiber Fabric Before You Approve the Garment
Choose the material by connecting the fiber description to the garment’s real failure points. Confirm the polymer and percentages, construction, finished GSM, width, stretch, recovery, coverage, surface, care route and test evidence. If a property is important enough to appear in the product brief, it is important enough to appear in the approval record.
Request a Custom Quote or send your moodboard or tech pack for review. Include the garment type, target quantity, color, reference fabric and any required test or labeling route. DTS Activewear can review the brief, clarify the material questions and connect the selected fabric to sampling before bulk production.
