What kind of thread is best for sewing double knit fabric?

When it comes to sewing double knit fabric, selecting the right thread is crucial for achieving a professional and durable finish. As a supplier of double knit fabric, I understand the importance of this decision and the impact it can have on the final product. In this blog post, I'll share insights on what kind of thread is best for sewing double knit fabric, considering factors such as thread type, weight, and color.

Understanding Double Knit Fabric

Before delving into thread selection, it's essential to understand the characteristics of double knit fabric. Double knit is a type of knitted fabric that consists of two layers of knitting stitched together. This construction gives the fabric its unique properties, including stability, stretch, and thickness. Double knit fabrics are commonly used in a variety of applications, such as clothing, upholstery, and accessories.

There are different types of double knit fabrics, each with its own characteristics. For example, Balanced Interlock Fabric offers a good balance of stretch and stability, making it suitable for a wide range of garments. Wear Knit is known for its durability and resistance to wear, making it ideal for items that will be subjected to frequent use. Underwear Interlock is a soft and comfortable fabric often used for underwear and loungewear.

Thread Type

The type of thread you choose for sewing double knit fabric depends on several factors, including the fabric's weight, stretch, and the intended use of the finished product. Here are some common thread types and their suitability for double knit fabric:

Cotton Thread

Cotton thread is a popular choice for sewing double knit fabric, especially for lightweight to medium-weight fabrics. It has good strength and is relatively easy to work with. Cotton thread is also breathable, which makes it suitable for garments that will be worn close to the skin. However, cotton thread may not be the best choice for fabrics with a high stretch content, as it may not stretch enough to keep up with the fabric's movement.

Polyester Thread

Polyester thread is another excellent option for sewing double knit fabric. It is strong, durable, and has good resistance to abrasion and fading. Polyester thread also has some stretch, which makes it suitable for fabrics with a moderate to high stretch content. Additionally, polyester thread is less likely to shrink or wrinkle compared to cotton thread, making it a good choice for items that will be washed frequently.

Nylon Thread

Nylon thread is known for its high strength and elasticity. It is often used for sewing heavyweight or stretchy fabrics, such as double knit fabric. Nylon thread can withstand a lot of stress and is less likely to break or fray. However, nylon thread may be more difficult to work with compared to cotton or polyester thread, as it can be slippery.

Silk Thread

Silk thread is a luxurious option for sewing double knit fabric. It has a smooth and lustrous appearance, which can add a touch of elegance to the finished product. Silk thread is also strong and has good elasticity. However, silk thread is more expensive than other thread types and may require special care when sewing.

Thread Weight

The weight of the thread you choose is also important when sewing double knit fabric. Thread weight is typically measured in denier or tex. Denier is a unit of measurement that indicates the weight of 9,000 meters of thread, while tex is a unit of measurement that indicates the weight of 1,000 meters of thread.

For lightweight double knit fabrics, a finer thread weight, such as 40 or 50 denier, is usually sufficient. This type of thread will be less visible on the fabric and will not add too much bulk. For medium to heavyweight double knit fabrics, a heavier thread weight, such as 60 or 80 denier, may be more appropriate. This type of thread will provide more strength and durability.

Thread Color

The color of the thread you choose should match or complement the color of the double knit fabric. This will ensure that the stitches blend in with the fabric and create a professional-looking finish. If you're using a patterned fabric, you may want to choose a thread color that matches one of the colors in the pattern. Alternatively, you can choose a neutral thread color, such as black, white, or gray, that will work with any fabric color.

Tips for Sewing Double Knit Fabric

In addition to choosing the right thread, there are several other tips that can help you achieve a successful sewing project with double knit fabric:

• Use the right needle: Choose a needle that is appropriate for the weight and type of double knit fabric you're using. A ballpoint or stretch needle is usually a good choice for sewing knit fabrics, as it will prevent the needle from snagging or damaging the fabric.
• Adjust the tension: Double knit fabric can be stretchy, so it's important to adjust the tension on your sewing machine to ensure that the stitches are even and secure. You may need to experiment with different tension settings to find the right one for your fabric.
• Stitch slowly: Double knit fabric can be thick and heavy, so it's important to stitch slowly to prevent the fabric from bunching or puckering. This will also help you maintain control over the sewing process and ensure that the stitches are straight and even.
• Use a walking foot: A walking foot is a special type of presser foot that helps to feed the fabric evenly through the sewing machine. This can be especially helpful when sewing double knit fabric, as it can prevent the fabric from shifting or stretching during the sewing process.

Conclusion

Choosing the right thread for sewing double knit fabric is essential for achieving a professional and durable finish. By considering factors such as thread type, weight, and color, you can select the thread that is best suited for your project.
