Overview of Types of Knit Fabrics: Weft vs. Warp Knits
Knit fabrics are divided into two primary categories: weft knits and warp knits. Each type has unique characteristics that influence its appearance, stretch, and functionality.
Weft Knits
Weft knits are among the most common knit fabrics. In this method, a single yarn runs horizontally across the fabric, creating loops that interlock row by row. This structure gives weft knits their signature stretch and softness. You'll often find weft knits in everyday clothing like t-shirts, sweaters, and leggings.
One key feature of weft knits is their flexibility. These fabrics stretch more in the crosswise direction, making them ideal for clothes that need comfort and movement. However, they can unravel if a loop breaks, so handling them carefully is essential. Weft knits also tend to curl at the edges, which you should consider when cutting or sewing.
Warp Knits
Warp knits differ significantly from weft knits. In warp knitting, multiple yarns run vertically, forming loops that interlock in a zigzag pattern. This construction makes warp knits more stable and less stretchy than weft knits. You'll often see warp knits in sportswear, lingerie, and upholstery.
Warp knits resist unraveling, even when damaged, which adds to their durability. They also maintain their shape better over time, making them suitable for structured clothes. While they lack the elasticity of weft knits, their strength and stability make them a reliable choice for many applications.
Here is a comparison between weft and warp knits presented in a table format:
| Feature | Weft Knits | Warp Knits |
|---|---|---|
| Formation | Formed by looping yarn horizontally. | Formed by looping yarn vertically. |
| Yarn Requirements | Requires one yarn for a series of loops. | Requires multiple yarns simultaneously. |
| Elasticity | More elasticity, especially in width. | Less elasticity, more stable structure. |
| Unraveling | Can easily unravel if a loop breaks. | Less likely to unravel easily. |
| Machine Used | Circular or flat knitting machines. | Tricot or Raschel knitting machines. |
| Common Uses | Sweaters, socks, and casual wear. | Lingerie, swimwear, and sportswear. |
| Fabric Texture | Generally softer and more flexible. | Firmer and less stretch than weft knits. |
| Design Complexity | Easier to create intricate patterns. | More limited in design capabilities. |
A Fabric Guide to Types of Weft Knit Fabrics
Weft knit fabrics come in various styles, each offering unique characteristics and applications. Below, you'll explore some of the most popular types of fabrics.
1. Jersey Knit
Jersey knit fabric is one of the most common and recognizable knit fabrics. It features a smooth surface on the right side and a slightly textured wrong side. This fabric is lightweight, breathable, and has a natural stretch, making it ideal for t-shirts, dresses, and casual wear.
You'll appreciate its softness and how it drapes well on the body. But jersey knit tends to curl at the edges when cut, so it's essential to handle it carefully during sewing.
2. Rib Knit
Rib knit fabric stands out for its distinct vertical ridges, created by alternating knit and purl stitches. This structure gives rib knit excellent elasticity, especially in the crosswise direction. You'll often find it used in cuffs, collars, and waistbands, where stretch and recovery are crucial.
Rib-knit also provides a snug fit, making it a popular choice for fitted clothes like tank tops and sweaters. Its durability ensures that it maintains its shape even after repeated use.
3. Interlock Knit
Interlock knit is a double knit fabric that offers a smooth surface on both sides. It's thicker and more stable than a jersey knit, providing a soft and luxurious feel. This fabric doesn't curl at the edges, making it easier to work with during sewing.
Interlock knit is commonly used in baby clothes, activewear, and loungewear due to its comfort and durability. Its structure also makes it less prone to stretching out of shape over time.
4. Purl Knit
Purl knit fabric stands out for its unique texture and reversible design. Unlike other types of knit fabrics, purl knit has a bumpy surface on both sides. This construction gives the fabric a soft, textured feel for cozy clothes like cardigans.
You'll notice that the purl knit stretches more in the vertical direction. This feature makes it ideal for clothing that requires flexibility and comfort. But it can be slightly heavier than other fabrics.
5. French Terry
French terry fabric is a popular knit fabric known for its looped texture on one side and smooth surface on the other. It offers the perfect balance between comfort and functionality.
You'll often find it used in casual wear like sweatshirts, hoodies, and joggers. The loops on the inside help trap warmth, while the smooth outer surface gives the fabric a polished look.

11. Cable Knit
Cable knit fabric stands out for its intricate, raised patterns that resemble twisted ropes or braids. These designs are created by crossing stitches over one another, giving the fabric a textured and decorative appearance. You'll often find cable knit used in scarves and blankets, where both style and warmth are essential.
12. Pointelle Knit
Pointelle knit fabric features delicate, openwork patterns that add a touch of elegance to any clothing. These patterns are created by strategically placed holes, forming decorative designs throughout the fabric. Pointelle knit is often used in lightweight tops and baby clothing due to its soft and breathable nature.
This fabric provides a feminine and vintage-inspired look, making it a favorite for romantic and delicate designs.
13. Velour knit

Practical Tips for Selecting Knit Fabrics
Choosing the right knit fabric can significantly impact the success of your project. Focusing on a few key factors ensures that the fabric you select meets your needs.
- Check Stretch and Recovery: Determine how much stretch the fabric has and how well it recovers its shape after being stretched. This is crucial for fitted garments.
- Assess Weight and Drape: Consider the weight and drape of the fabric to ensure it suits the intended garment type.
- Feel the Texture: Touch the fabric to gauge its softness and texture, ensuring it feels comfortable against the skin.
- Examine Color and Print: Look for consistent coloring and print quality. Ensure patterns align properly if you plan to sew multiple pieces together.
- Consider Fabric Content: Check the fiber content label to understand its properties, such as polyester, spandex, or rayon.
- Test Durability: Look for tightly knit fabrics for more durability, especially for items that will see frequent use or washing.
- Test for Transparency: Hold the fabric to light to check for transparency. If not desired, lining might be required.
- Buy a Sample First: If possible, purchase a small sample to test how it behaves when washed and sewn.
- Consider Project Needs: Match the fabric's characteristics, such as stretch, weight, and warmth, with the specific needs of your sewing project.
