Understanding Knit Fabrics and Sewing Machine Requirements

Knit fabrics, also known as knits, are a popular choice for sewing due to their softness, flexibility, and moisture-wicking properties. However, sewing knit fabrics requires special consideration and the right technique to achieve professional-looking results. In this section, we will explore the differences between knit and woven fabrics, the unique characteristics of knit fabrics, and the types of knit fabrics that can be worked with.

Differences Between Knit and Woven Fabrics

Knit and woven fabrics differ in their construction methods and resulting properties. Woven fabrics are created by interlacing threads perpendicularly, whereas knit fabrics are created by interlooping yarns in a series of connected loops. This fundamental difference affects the fabric’s appearance, drape, and stitch quality.

Appearance: Knit fabrics have a more subtle sheen than woven fabrics, and their texture can vary greatly depending on the yarn type and gauge. Woven fabrics, on the other hand, have a more pronounced grid pattern and a stiffer texture.
Drape: Knit fabrics drape smoothly and naturally around the body, making them ideal for garments that require a fitted silhouette. Woven fabrics, however, can be more prone to wrinkles and may require additional draping techniques for a smooth appearance.
Stitch quality: Knits are generally easier to sew than wovens, as the loops of the fabric allow for a smooth feed under the needle. However, wovens can be more challenging to sew due to their grid structure, which can cause skipped stitches or puckering.

Unique Characteristics of Knit Fabrics

Knit fabrics have several characteristics that require special consideration when using a sewing machine:

• Stretchiness: Knits can stretch up to 5-10% of their original length, making it essential to choose a machine with high stitch density and stability.
• Looped structure: Knits’ looped structure can cause the fabric to pull or bunch under the needle, leading to uneven stitches or fabric distortion.
• Fraying: Knits are prone to fraying, especially at seams, which can lead to a rough, uneven finish.

Types of Knit Fabrics and Their Respective Difficulties

Different types of knit fabrics have varying difficulties when it comes to sewing:

Jersey fabrics (e.g., cotton, poly, or blends): These are the most common type of knit fabric and are considered relatively easy to work with. They have a tight weave and a smooth texture.
Interlock fabrics (e.g., cotton, poly, or blends): Interlock fabrics are similar to jersey fabrics but have a more rigid texture and a slightly tighter weave, making them more challenging to sew.
Stretch velvet fabrics (e.g., cotton, poly, or blends): These fabrics have a plush pile and a stretchy backing, requiring high stitch density and care when sewing to avoid distortion.
Knit wovens (e.g., mesh or double-knit): Knit wovens have a unique blend of knit and woven properties, often requiring specialized techniques and settings to achieve professional-looking results.

Sewing Machine Requirements

To sew knit fabrics effectively, you’ll need a machine that can handle the fabric’s unique characteristics:

High stitch density: Look for a machine with adjustable stitch length and width settings to accommodate the stretchiness of knit fabrics.

Pre-washing and Pre-shrinking Knit Fabrics

Pre-washing and pre-shrinking knit fabrics are crucial steps in preparing them for sewing. This process helps to remove any excess dye, finishes, or impurities that might affect the fabric’s color, texture, or shrinkage.

Wash the fabric in cold water using a mild detergent to remove any excess dye, finishes, or impurities.
Allow the fabric to dry completely before washing it again in cold water with a small amount of vinegar to stabilize the fabric’s pH levels.
After the second wash, remove excess water from the fabric without wringing it, as this can cause distortion and shrinkage.
Allow the fabric to air dry again, and then re-measure the fabric to determine its new dimensions.

Handling Stretchy Knit Fabrics

Stretchy knit fabrics require special care when handling and sewing. Here are some tips to keep in mind:

When handling stretchy knit fabrics, it’s essential to use your hands, rather than your fingers, to prevent pinching or creasing the fabric.
Use a stretch gauge or tape measure to measure the fabric’s stretch percentage, which will help you determine the best sewing techniques and thread weights to use.
When sewing, use a longer stitch length to accommodate the fabric’s stretch, and press the seams with a hot iron to secure the fibers.
When turning raw edges, use a serger or zigzag stitch to prevent fraying, and use a stabilizing material like interfacing or fusible web to support the fabric.

Sewing Techniques for Knit Fabrics

Sewing on knit fabrics requires a different set of skills and techniques compared to sewing on woven fabrics. Knit fabrics have a unique texture and elasticity that can make them challenging to work with, but with the right techniques and stitches, you can achieve professional-looking results.

When sewing on knit fabrics, it’s essential to consider the grain of the fabric. The grain refers to the direction of the yarns in the fabric, and sewing perpendicular to the grain can cause the fabric to distort or stretch unevenly. To avoid this, always sew on the grain or in a direction that follows the natural fibers of the fabric.

Understanding Knit Fabric Grain

The grain of a knit fabric can be identified by the way the yarns are arranged. For example, a stretchy fabric like spandex might have a smooth, even texture when pulled in different directions, while a fabric with a more open weave, like a sweater knit, might have a looser texture. Understanding the grain of your fabric is crucial for sewing successfully.

Look for the direction of the seams: If the seams of your fabric run in a specific direction, it’s likely that the grain runs in that direction.
Check the texture: If the fabric has a smooth, even texture, it’s probably on grain. If it has a more uneven or loose texture, it might be off grain.
Test the fabric: Gently pull the fabric in different directions to see how it stretches and behaves. If it stretches easily in one direction but not the other, it’s likely that the grain runs in that direction.

Knit-Specific Stitches

When sewing on knit fabrics, it’s essential to use stitches that allow for flexibility and stretch. Some common knit-specific stitches include:

Blind hem stitch
Overlock stitch
Stretch stitch
