Do You Need to Use Special Thread for Spandex?

While cotton thread may be suitable for many fabric types, it may fall short when it comes to spandex. The unique properties of spandex, such as it’s stretch and elasticity, require a thread that can withstand the fabric's movements without breaking or snapping. That's where polyester thread comes into play. Polyester thread offers the perfect combination of strength and flexibility, making it an ideal choice for sewing spandex.

Can You Sew Spandex With Regular Thread?

When it comes to sewing spandex, many people wonder if it’s possible to sew it with regular thread. However, there are a few things you need to keep in mind.

Secondly, you’ll need to adjust the tension settings on your sewing machine. By adjusting the tension settings, you can ensure that your stitches aren’t too tight and won’t snap when the fabric is stretched.

Another important factor to consider when sewing spandex is the type of needle you use. This type of needle has a rounded tip that allows it to slide between the fibers of the fabric, reducing the risk of snags or skipped stitches.

Additionally, when sewing spandex, it’s important to use a stretch stitch or a zigzag stitch. It’s also recommended to use a shorter stitch length to ensure that the stitches are secure.

Tips for Choosing the Right Needle for Sewing Spandex

When working with spandex fabric, it’s important to choose the correct needle to ensure the best results. Here are some tips to consider when selecting a needle for sewing spandex:

1. Needle size: Use a smaller needle size, such as size 9 or 11, to prevent excessive stretching or snagging of the fabric. This will help maintain the integrity of the spandex.

2. Needle type: Opt for a ballpoint or stretch needle specifically designed for knit fabrics. These needles have a rounded tip that slides between the fabric’s fibers, minimizing any potential damage.

3. Needle quality: Invest in high-quality needles to minimize the risk of breakage or bending. Cheap needles may not be strong enough to handle the stretch and resilience of spandex.

4. Test stitches: Before starting your project, test different needles on a scrap piece of spandex fabric. This will help you determine which needle produces the cleanest and most even stitches without causing any damage.

5. Replace regularly: Needles wear out over time, so replace them regularly, especially if you’re working on large or complex projects. A dull or worn-out needle can result in skipped stitches or fabric damage.

Remember that choosing the right needle is crucial for sewing spandex successfully. By following these tips, you can ensure smooth and professional results.
