French Terry Fabric: Types, GSM & Sourcing

Who wrote this: This guide comes from the knitting floor team at Shaoxing Keqiao Lianyang Fabric Co., Ltd (Pura Fabric), a weft-knit fabric manufacturer established in 2010 in Keqiao, Shaoxing, China, operating 52 circular knitting machines across a 4,000 sqm facility. The specification logic below is the same checklist we use when we quote on our own floor.

French terry fabric is one of the most requested constructions in the knitwear market, and it is also one of the most frequently specified badly. The word gets used for anything with a fuzzy face, which means mills quote against it, buyers receive samples that do not match what they pictured, and the fabric gets ordered twice before it is right.

This guide works through what French terry actually is, how the loop is built, how it behaves in the wash, and how to specify it for bulk production — including the six points that most often separate a good delivery from a disappointing one. It is written for garment and fabric buyers who need to specify rather than for readers who are only curious.

What Is French Terry Fabric?

French terry is a three-dimensional knit defined by one thing: the pile. Thousands of tiny yarn loops are raised off the ground plane on the face of the fabric, creating a soft, spongy surface with visible depth, while the back stays flat and smooth with the anchoring points visible as a fine dotted texture. That two-sided structure — loop face, flat back — explains most of the performance characteristics buyers care about, and it is why the fabric behaves differently from both woven toweling and single-jersey knit.

The name is frequently confused with two other constructions. Terry cloth is the broader family, and it includes both French terry and Chinese terry, distinguished mainly by the yarn used in the pile. Chinese terry typically uses a finer, more uniform yarn, produces a denser pile, and is often brushed or sheared on the face for extra softness. French terry generally uses a slightly coarser spun yarn, a lower pile density, and retains a visible loop texture rather than a brushed one. When a buyer specifies “French terry” they are usually asking for the visible loop, a moderate pile, and the characteristic soft-but-structured handle that comes from a three-end fleece yarn.

The loop is not decorative. It creates air space between fabric and skin, which is why French terry dries slower than flat knit but feels warmer when damp, and it wicks along the yarn rather than across the surface, moving moisture outward and leaving a soft layer rather than a clammy one. For anyone specifying for sweatshirts, hoodies, towels or robes, those two behaviours are usually the deciding factors.

The fabric is knitted, not woven, on circular or flat knitting machines. This matters commercially: knitted fabric can be cut and sewn without the fraying that woven edges require, it stretches in both directions, and it does not have a grain line that constrains pattern layout. A buyer moving from woven toweling to French terry is buying that freedom as much as the texture.

The Loopback Structure: Why It Behaves the Way It Does

Understanding the loop is the difference between specifying French terry correctly and guessing at it. A loop forms when one yarn is manipulated so that part of it rises above the ground plane instead of lying flat. Because that loop is continuous with the ground loop, it is structurally part of the fabric rather than a separate yarn sitting on top — which is why French terry does not shed or pill off the way a brushed or flocked surface does.

Three variables define the resulting fabric, and all three should be specified rather than assumed.

Pile height is the length of the raised loop. It is the most visible difference between a lightweight summer terry and a heavy winter one. Short loops produce a flatter, faster-drying, more fabric-like surface; long loops produce a shaggy, warmer, more towel-like surface. The trade-off is direct: longer loops add warmth and bulk, reduce air permeability, and increase drying time.

Loop density is the number of loops per square centimetre. Dense loops give a firm, plush, fast-recovering surface that resists flattening. Sparse loops give a softer, more open surface that compresses readily and dries faster. This is often confused with GSM but the two are independent — a fabric can be heavy because of the ground fabric while having a sparse, open loop, and it will behave very differently from a fabric of the same weight with dense loops.

Yarn composition in the pile matters more than buyers expect. The ground yarn provides the body and the recovery; the pile yarn provides the feel. A cotton pile gives a soft, absorbent, low-static surface. A polyester pile dries faster, holds its loft through more wash cycles, and has lower water absorption. A bamboo or viscose blend adds a smoother, silkier hand but at a lower strength, which matters for garments that will be laundered commercially. Common specifications are 100% cotton pile on a cotton or TC ground, and cotton/polyester blends where fast drying and durability are the priority.

Specification	Low	Mid	High	What it changes
Ground GSM	180 gsm	240–280 gsm	320 gsm+	Body, opacity, recovery, cost
Pile height	1.0–1.5 mm	1.8–2.5 mm	3.0 mm+	Warmth, air permeability, drying time
Loop density	Sparse, open	Standard	Dense, plush	Firmness, pilling resistance, compressibility
Pile yarn	100% cotton	Cotton/poly blend	Poly or bamboo blend	Hand feel, absorbency, drape, laundering life
Stitch definition	Plain	Rib	Interlock-backed	How flat the loops sit under tension

One practical consequence deserves emphasis. Loop compressibility is what buyers report as pilling, and it is not a fibre problem. A high-compression terry will look flattened after a few washes and stay flattened. A denser loop with a higher-twist yarn, or a fabric whose pile is anchored through a finer ground, will look far better after the same number of cycles. If a buyer says the fabric pills, the useful question is whether the compression is in the pile or in the ground.

French terry knit fabric is what most people mean when they ask for a sweatshirt fabric that feels substantial without being heavy. The knit construction is what gives it the characteristic combination: the softness and warmth of a pile surface with the recovery and drape of a knitted back. A woven towelling cloth of similar weight will feel stiff and will not recover from a crease.

Where the requirement is instead a smooth surface with recovery — a fitted tee, a lining, an activewear top — an interlock knit is the more appropriate construction, and it is worth being clear about which of the two you are specifying before the fabric is made.

French Terry Versus Regular Terry

Both are loop-pile knits, and the practical differences come down to yarn, loop density and finishing. This is a genuine commercial distinction in some markets, largely historical, but the specification still matters when a buyer is comparing two quotes.

Attribute	French terry	Chinese terry
Pile yarn	Cotton, cotton blends, open-spun	Finer combed or compact yarn
Loop appearance	Visible, soft, open loops	Dense, fine, often brushed or sheared
Hand feel	Soft, matte, spongy	Smoother, denser, sometimes slick after brushing
Dry time	Slower — loft traps air	Faster — denser surface releases water
Bulk at equal GSM	Higher, due to pile	Lower, surface is flatter
Typical use	Sweatshirts, hoodies, lounge, towels	Robes, premium towels, brushed finishes

Two further points get missed in this comparison. A heavier French terry and a lighter Chinese terry can end up behaving more similarly than a heavy Chinese and a light French, because pile height matters more to the hand than the yarn label. And when choosing between them, the deciding question is usually the end use: a loop for a sweatshirt wants a visible, compressible texture, while a loop for a bath towel wants density, absorbency and fast drying, and is often brushed or sheared to get there.

Terry Knit Construction

French terry is produced on weft knitting machines, and understanding the construction helps a buyer specify correctly and predict behaviour in the cutting room.

On a single-face terry the loops are knitted on one side only. This is the commonest form and the most economical. It has a flat, sometimes slightly stiff back and it is the version most often used for sweatshirt bodies. Because the loop is anchored to a single ground layer, a single-face terry has less recovery than a double-face construction and can feel thinner at the same GSM.

On a double-face or interlock-backed terry, the back is knitted as a separate, finer layer that is joined to the loop face. This doubles the structural base, adds significant body and recovery, prevents the loop side from distorting when the garment is stretched, and gives a cleaner, more opaque back. It is the version to specify for premium tees, fitted garments, and anything that will be laundered repeatedly, at a higher cost per metre.

Machine gauge matters less than buyers expect, but two points are worth knowing. A finer gauge (for example 24 gauge against 20 gauge) produces a finer, denser loop and a smoother surface, at the cost of machine output. A coarser gauge produces a more pronounced, more open loop. Machine gauge is one of the reasons two terries of identical GSM and identical fibre can look and feel quite different.

Fabric width matters commercially here in a way it does not for flat knits. A terry with a tall pile requires a wider valid cuttable width than its overall width implies, because the pile compresses at the selvedge. Where a buyer specifies overall width, the mill may deliver a fabric whose usable width is 10–15 cm narrower than expected. Specifying valid cuttable width removes that as a production risk.

GSM, Weight and What to Specify When Ordering

For stretch-related constructions, see our rib knit material guide, and for the fibre and colour families referenced in the tables above, our guide to pink and black fabric types.

Weight is the first specification a buyer asks for and the last one they should rely on. Because terry gets its bulk from the pile rather than the ground, two fabrics at the same GSM can feel very different. Use GSM as a rough category, then specify the ground construction separately.

End use	Typical GSM	Pile height	Notes on construction
Lightweight sweatshirt / lounge top	180–220	1.0–1.5 mm	Single face usually acceptable; fast drying
Standard sweatshirt	240–280	1.8–2.5 mm	Most common spec; single or double face
Hoodie / heavier sweatshirt	280–320	2.0–3.0 mm	Double face preferred for recovery and opacity
Bath towel	350–450	3.0 mm+	Dense pile, often sheared; absorbency is the spec
Robes / loungewear	320–400	3.0 mm+	May be brushed on the face for a softer finish
Activewear / quick-dry	180–240	1.0–1.5 mm	Poly or TC pile; flat surface dries faster

Before ordering, there are five points worth settling in writing.

• Specify valid cuttable width, not overall width. Pile compresses at the edges. Where a high-pile terry is supplied at 180 cm overall, a usable width closer to 160 cm should be expected unless the mill states otherwise.
• State shrinkage tolerance and the test method. Pile fabrics shrink more than flat knits, and the figure varies with fibre and finishing. A tolerance of 3% or 5% is normal, but the method must be named.
• Name the pile yarn separately from the ground yarn. A fabric described as “80% cotton” may refer to the ground only. Specify both.
• Confirm whether the loop is brushed or sheared. Brushing and shearing change the hand substantially and are not interchangeable.
• Recalculate yardage for the finished garment. Heavier terry consumes more metres per garment at the same width. Use our garment yardage calculator to model the actual consumption before committing.

Composition and Fibre Choices

Fibre choice in French terry is a trade-off between absorbency, hand feel, drying time and laundering life, and the right answer depends on the end use rather than on a general preference for one fibre.

100% cotton is the reference point. It is the most absorbent, has the softest matte hand, and launders well. It is also the slowest to dry and the most prone to shrinkage. Where a garment is worn next to skin and washed frequently, cotton is usually right.

Polyester or TC terry is chosen for fast drying, low weight and durability — activewear, travel items, and lining or layering components. It does not absorb well, so it should not be specified for a towel. Cotton/polyester blends are the workhorse for bulk programs: the polyester adds strength, reduces shrinkage, speeds drying and extends loop life under repeated commercial laundering.

Bamboo, lyocell and viscose blends are used where a smoother, silkier hand is wanted. They drape better and feel cool against the skin. They are also weaker when wet and tend to be more expensive, so they are generally reserved for premium loungewear and skin-contact layers rather than high-wash programs. Our terry cloth material guide covers the fibre question in more detail.

Finishes That Change the Fabric

The same base construction can be changed substantially by finishing, and these changes need to be specified rather than assumed.

Peaching or brushing raises an additional fibre layer on the face, giving a peach-skin or brushed-back hand and a warmer, drier surface. It reduces the visible loop texture, so a brushed fabric and a loop fabric should never be described interchangeably in a specification. It also increases warmth and reduces drying speed.

Shearing trims the loop to a uniform, even height. A sheared terry looks precise and dense, holds a flat surface under tension, and is often chosen where a clean appearance matters more than maximum loft.

Mercerizing is used on cotton terries to increase lustre, dye depth and strength. It is worth confirming whether a mercerized finish is present, because it changes both the appearance and the cost. Anti-pilling treatments are also worth specifying where the fabric will be washed at high temperature or in a commercial laundry, since they reduce the surface fuzz a loop fabric can develop.

Moisture management and antimicrobial finishes are used on performance terries, usually on a synthetic base. We produce antibacterial and moisture-wicking blends for activewear programs — a useful reference point when specifying functional terry.

Every one of those points is settled more easily when the fibre is decided early, because fibre choice constrains construction, finishing and care. Our guide to terry cloth material sets out the fibre question on its own, and it is worth reading before the specification is written rather than after the first sample arrives.

Terry Compared with Other Knits

Buyers often arrive at terry having considered other knits. The distinctions below are the ones that matter in specification.

Construction	Face surface	Bulk source	Warmth	Drying speed	Typical use
French terry	Visible loops	Pile on a single ground	High	Slow	Sweatshirts, hoodies, towels
Jersey	Flat, smooth	Ground only	Low	Fast	Tees, lining, layering
Interlock	Flat, smooth	Two knitted faces	Medium	Medium	Premium tees, activewear
Fleece	Brushed surface	Brushed fibre on knit	Very high	Slow	Sweatshirts, blankets, warmwear
Sherpa	Dense pile, often curly	High pile on knit or woven	Very high	Slow	Winter jackets, hoodies, blankets
Pique	Raised textured pattern	Double knit	Low	Fast	Polo shirts, collars

Blend	Typical Composition	Resulting Characteristics	Common Use
100% Cotton	100% Cotton (often ring-spun or combed)	Natural, breathable, soft hand. Can shrink more. Traditional feel.	Premium basics, loungewear, eco-conscious lines (if organic).
Cotton/Polyester	60/40, 80/20, or 50/50 blends	Improved durability, wrinkle resistance, colorfastness, and reduced shrinkage. Often more affordable.	Mass-market hoodies, team uniforms, everyday activewear.
Cotton/Rayon (or Modal/Lyocell)	Typically 60/40 or 70/30	Incredibly soft, drapey hand. Enhanced moisture management. More luxurious feel than poly blends.	Luxury loungewear, high-end basics, drapey silhouettes.
Synthetic-Dominant	Polyester/Spandex or Nylon/Spandex	Maximum stretch, moisture-wicking, quick-drying, shape retention. Less natural feel.	Performance activewear, athletic layers, travel apparel.

Two distinctions in the above table are worth drawing out, because they are the ones that come up most often in specification conversations.

Feature	French Terry	Fleece	Jersey	Terry Cloth (Woven)
Construction	Weft knit with uncut loops on back	Weft knit with cut loops (sheared) on back	Smooth weft knit, no loops	Woven fabric with extra weft yarns forming loops on one or both sides
Back Texture	Looped, textured	Napped, plush, fuzzy	Smooth	Very prominent, absorbent loops
Breathability	Good (due to air pockets in loops)	Poor to Fair (napping compresses structure)	Excellent (thin, open structure)	Good (loop structure allows air)
Warmth	Moderate (traps air in loops)	High (dense nap insulates well)	Low (thin)	High (thick, looped)
Stretch	Good 2-way or 4-way (if blended with Lycra/Spandex)	Good 2-way	Excellent 2-way	Very Limited (woven)
Typical Use	Sweatshirts, hoodies, loungewear, casual dresses	Fleece jackets, blankets, cold-weather layers	T-shirts, underwear, dresses	Bath towels, beachwear, robes

The practical takeaway: if the loop is not wanted in the final appearance, terry is the wrong choice. Fleece gives similar warmth with a brushed face and a different surface character, and a French terry that has been brushed is effectively moving toward fleece with the wrong specification. Decide which of the two you are buying before the fabric is made.

Sourcing French Terry Fabric in Bulk

Most buying problems with French terry come from specifying it as “terry fabric” and nothing more. That description permits almost any construction, and a mill can legitimately deliver something quite different from what was imagined. The following points are what a buyer should establish in writing before the order is placed.

Points to settle with the mill

• Construction: single-face or double-face / interlock-backed.
• Total weight and pile height, stated separately, plus the tolerance on each.
• Valid cuttable width, not overall width.
• Ground and pile fibre content stated separately, with the blend ratio of each.
• Finish: loop, brushed/peached, or sheared.
• Shrinkage tolerance and test method — specify the standard, not just the number.
• Colour fastness target for the intended washing regime.
• Batch consistency tolerance across a production run, if you are ordering more than one dye lot.

Verifying what you received

Three checks catch most specification failures at goods-in, and all three take minutes.

First, check the weight against the stated GSM on a calibrated balance, sampling several points across the roll. A fabric delivered well under the stated weight will not recover the loft it was specified for.

Second, measure the valid cuttable width under light tension, not the overall width. A difference of more than about 12 cm between stated overall width and measured valid width is a red flag worth raising at goods-in rather than discovering at the cutting table.

Third, press a swatch and observe the recovery. Compress the face firmly, release it and let it sit. A fabric with a well-anchored loop recovers within a minute or two. One that stays compressed will look flattened after a small number of wash cycles, whatever the fibre content claims.

What changes between sample and bulk

Two things routinely move between an approved sample and the production roll. Shrinkage increases with bulk processing because the fabric is relaxed in bulk dyeing and finishing rather than in a single sample batch. Hand feel can shift if the loop is sheared or brushed slightly differently, or if the pile yarn is substituted with a visually similar but different blend.

Both are managed by specification rather than by inspection alone: state the shrinkage tolerance and the finishing route in the order, and confirm the finishing route on a pre-production sample before the bulk dye lot is released.

For guidance on the specification points above, or for a quote against a particular construction, tell us the end use, target weight and width and we will come back with what we can actually run.

Care, Washing and Longevity

French terry ages well if handled properly and ages badly if it is not, and most of the difference comes from heat rather than detergent.

Wash at 30–40°C. A high-temperature cycle sets any residual relaxation permanently, which is why a fabric that measures within tolerance at the mill can still shrink noticeably after the first domestic wash. Cold or cool cycles preserve the loop and the fit.

Wash inside out where the loop is brushed or peached. The raised surface abrades against the garment’s interior. Turning it inside out materially reduces the wear on the face over repeated cycles.

Avoid high tumble heat. Tumble drying is the main cause of loop compression and the flattened appearance buyers report as quality decline. Air drying flat preserves the loft.

Do not use fabric softener on the pile. Softener coats the fibre and reduces its absorbency over time. It will make the fabric feel better immediately and perform worse after several washes, which is the wrong trade for a towel or a bathrobe.

Expect the loft to compress with use and recover on drying. A high-quality terry will flatten under wear and lift back as the garment dries. That behaviour is the correct test of loop quality. A fabric that stays flat after drying has a poor loop anchor, regardless of what the specification sheet says.

For the fibre and finishing detail behind these points, our guide to cotton French terry goes deeper, and the warm-weather considerations cover the seasonal question specifically.
