English 
中文简体 If you've received a fabric specification that simply says "flat woven fabric," you already know the term can be misleading. In the strict textile definition, a flat woven fabric is a cloth made by interlacing warp and weft yarns at right angles on a loom, with no pile or raised surface. But in the apparel sourcing world, the same phrase is sometimes used for knitted flat fabrics—single- and double-faced jersey-like cloths that are flat in appearance but stretchy in behavior. Knowing which one you actually need is the first step toward a successful production run.
What Is Flat Woven Fabric?
Start with the conclusion: a flat woven fabric is any woven cloth with a flat, smooth surface, created by interlacing two sets of yarns — warp (lengthwise) and weft (crosswise). The simplest form is plain weave, where each weft yarn passes over one warp yarn and under the next, alternating on every row. This over-under construction gives the fabric strength, dimensional stability, and a lower amount of stretch compared with knit fabrics.
Because the surface has no loops or piles, flat woven fabrics tend to print well, resist pilling, and hold their shape after repeated washing. They are also relatively easy to cut and sew, which is why they dominate the shirting, dress, and home textile categories.
For a visual reference, you can examine the pieces in our flat woven fabric collection.
Key Types of Flat Woven Fabric
Not all flat woven fabrics are equal. The arrangement of the interlacing pattern creates three main families:
- Plain weave. The simplest and most common. Taffeta and poplin are examples. It offers a balanced hand, good durability, and a crisp surface.
- Twill weave. Defined by diagonal lines formed by offsetting the interlacing points. Denim, gabardine, and chino are twill fabrics. They are more flexible and drape slightly better than plain weaves while still remaining firm.
- Satin weave. This structure uses long floats of warp yarns on the surface to create a smooth, lustrous finish. Satin and sateen are examples. They feel softer but can snag more easily.
All three are technically flat woven fabrics because the surface is not piled. When you see the term "flat weave" in a product description, it usually refers to one of these structures.
Key Characteristics That Affect Purchasing Decisions
For a factory buyer, the most important characteristics are not just how the fabric looks but how it behaves in production and in the finished garment. The table below summarises the typical performance you can expect from a well-constructed flat woven fabric.
| Characteristic | Typical Range | Why It Matters |
|---|---|---|
| Tensile strength | High | Survives seaming and daily wear |
| Stretch | Low (1–5%) | Holds shape but limits body movement |
| Dimensional stability | Good | Minimal shrinkage after washing |
| Breathability | Depends on yarn count and density | Light cottons and linens breathe well |
| Surface feel | Smooth or slightly textured | Easy to laminate, print, or bond |
If the end use requires stretch, a pure flat woven fabric will not deliver it. That is why many sportswear and everyday garments are made from knitted flat fabrics, which we compare in the next section.
Flat Woven vs. Knitted Fabric: The Clearest Way to Compare
Here is where terminology often becomes confusing. A true woven fabric is made on a loom; a knitted fabric is made by interlocking loops on knitting machines. In the garment industry, the Chinese term "平织" (literally "flat weaving") is commonly used for both single-faced and double-faced knitted fabrics that have a smooth surface. These are not loomed fabrics, but they are called "flat woven" in some trading contexts.
So when a supplier says "flat woven fabric," you should confirm whether they mean a woven plain weave or a knitted flat cloth. The table below summarises the differences.
| Feature | Woven flat fabric | Knitted flat fabric |
|---|---|---|
| Production method | Weaving on loom | Knitting on circular or flat knitting machine |
| Stretch | Low | Moderate to high, depending on elastane content |
| Dimensional stability | Excellent | Can relax or shrink if not finished properly |
| Surface appearance | Smooth, no loops | Smooth face with possible loopback structure |
| Typical uses | Shirts, blouses, bedsheets, lining | T-shirts, dresses, sportswear, school uniforms |

Why Suppliers Use "Flat Woven" for Knitted Fabrics
In the export hubs of Zhejiang and Guangdong, the phrase "flat woven fabric" has taken on a second meaning. It is often used to describe a family of knitted fabrics with a flat, uniform surface: single jersey (single-sided flat cloth) and double jersey (double-sided flat cloth). These fabrics are produced on circular knitting machines and are valued for their smooth hand, light weight, and ability to combine with polyester or elastane.
For example, a 100D milk silk double-sided flat cloth has a smooth face on both sides and a soft brushed hand. The structure gives you the flat look of a woven fabric with the comfort and stretch of a knit. That makes it a practical choice for loungewear, casual jackets, and uniform programs.

A 50D single jersey in polyester is lightweight and tightly knitted, often used for linings and basic apparel. Both are called "flat" because they do not have the raised patterns of rib, pique, or jacquard.
How to Choose the Right Flat Fabric for Your Application
Answer three questions before you request samples. What is the final garment? How much stretch does it need? What are the washing and care requirements?
For dress shirts, blouses, and structured bottoms, a true woven flat fabric remains the standard. For knit-like comfort and flexibility, a knitted flat cloth is a better fit. If you are developing basic T-shirts or casual tops, a 50D polyester single jersey offers a smooth hand and good opacity at a competitive cost.

For lining applications, a 75D fully polyester single-sided flat cloth is a reliable workhorse. It is light, strong, and provides a clean low-profile finish that does not add bulk to the garment.

Finally, check the supplier's production capability. A factory with circular knitting machines in different gauges can cover a wider range of weights, densities, and hand feels. That flexibility matters when you need to move from development to production quickly.
Making the Final Call
Whether you need a true woven flat fabric or a knitted flat cloth, the most important thing is clarity. Use precise terms in your RFQ: specify "woven plain weave" or "single jersey," include fiber content, weight, and stretch requirements. This prevents sample mismatches and saves weeks of development time.
