Basic of Rib Fabric (Part 1)

Rib knits have a very high degree of elasticity in the crosswise direction. This knitted fabric is used for complete garments and for such specialized uses as sleeve bands, neck bands, sweater waistbands, and special types of trims for use with other knit or woven fabrics.

Characteristics of rib fabric:

  1. High Flexibility: Rib fabric is known for its exceptional flexibility, especially in the transverse (crosswise) direction, which makes it comfortable to wear without the use of rubber thread.
  2. Distinct Straight and Reverse Loops: Rib fabric features straight and reverse loops that are clearly visible on both sides of the fabric, creating a distinctive ribbed texture.
  3. Homogeneous Fabric: Rib fabric is considered a homogeneous fabric, meaning it has a consistent appearance and texture.
  4. Variations in Rib Patterns: Depending on the arrangement of straight and reverse loops, rib fabric can have different rib patterns, such as 2×2, 2×1, or 1×1 rib, each with its own visual and functional properties.
  5. Insulating Qualities: Rib fabric is effective at protecting the body from cold temperatures because it traps air between its layers, providing insulation and keeping the wearer warm.
  6. Non-Curling Edges: Rib fabric typically does not curl at the cut edges, which makes it easier to work with in sewing and garment construction.
  7. Minimal Stitch Escape: Stitch escape, where stitches unravel, is usually observed only at the last stitch, indicating good stitch stability.
  8. Higher Weight and Thickness: Rib fabric is heavier and thicker compared to some other types of fabrics, providing warmth and durability.
  9. High Elasticity and Elongation: Rib fabric exhibits high elasticity, allowing it to stretch and recover, making it suitable for applications where flexibility is required.
  10. Versatile Use: Rib fabric finds a wide range of applications in upper clothing, medical textiles, special sportswear, t-shirt skirts, collars, sleeves, knitted cuffs, hats, men’s socks, and similar areas due to its versatility and properties.

Use 2 set needle: Cylinder and dial

  1. Cylinder needles placed vertically: Cylinder needles are positioned vertically on the cylinder of the knitting machine. They move up and down in a circular motion to create the knit stitches.
  2. Dial needles placed horizontally: Dial needles are positioned horizontally on the dial of the knitting machine. They work in conjunction with the cylinder needles to create various stitch patterns and maintain tension in the fabric.

To identify rib fabric, look for these key characteristics:

  • Description: Rib knit fabric is double-faced (V shape) and reversible, meaning it looks the same on both sides.
  • Texture: You can feel the raised ribs when you touch the fabric. These ribs are produced by alternating between knit and purl stitches during the knitting process.
  • Rib Size: Pay attention to the size of the ribs. They can vary, with common sizes including 1×1 (one knit stitch followed by one purl stitch), 2×2 (two knit stitches followed by two purl stitches), 3×3 (three knit stitches followed by three purl stitches), or even uneven combinations like 1×3 (one knit stitch followed by three purl stitches).

Rib fabric comes in various sizes, typically defined by the arrangement of knit and purl stitches within the fabric. The most common rib sizes include:

  • 1×1: This means one knit stitch followed by one purl stitch, creating a small and tight rib pattern.
  • 2×2: Two knit stitches followed by two purl stitches, resulting in a slightly larger and more balanced rib pattern.
  • 3×3: Three knit stitches followed by three purl stitches, producing a broader rib pattern.
  • 6×6: Six knit stitches followed by six purl stitches, creating a wider and more pronounced ribbed texture.

Additionally, there are multisized rib patterns where the number of knit and purl stitches may vary, such as 4×6 or 2×4. These variations allow for different textures and visual effects in the rib fabric. The specific rib size used can vary based on the intended design and application of the fabric in clothing or other textile products.

In the knitting process, when every other wale alternates between plain and purl stitches on the right and back sides, it is called a 1 X 1 rib, or a plain rib.
The 1×1 rib is known for its elasticity and is commonly used in various knitwear items, including cuffs, collars, and hems, as it provides stretch and a snug fit.

The classic 2×2 rib stitch is formed by alternating two knit stitches and two purl stitches across all rows and stitches.

Tubular Rib Knit Fabric

Tubular rib knits are constructed and sold in a tube shape so there is no selvage. They are usually produced by circular knitting on special machines. They can be used to create seamless garments, as there are no side seams. It is a popular choice for clothing that needs to be tight-fitting and comfortable to wear close to the skin. Tubular fabric is also less likely to tear or fray.
