3. Interlocking with Bobbin Thread The bobbin case, which holds the bottom thread, is designed to catch this loop. As the needle continues to move up, the loop tightens around the bobbin thread, creating the lock stitch. Once the loop is locked in place, the needle continues its downward motion, pulling the newly formed stitch tight against the fabric.

When selecting strong sewing machine needles, it’s crucial to consider the type and weight of the fabric you will be working with. For instance, a size 90/14 heavy-duty needle is suitable for thicker fabrics like canvas and upholstery, while a 100/16 needle can handle even tougher materials. Additionally, it’s important to match your thread type with the needle; for example, using heavier thread with a needle designed for thicker materials ensures that both components work harmoniously.
Conclusion
Industrial sewing machines for auto upholstery are engineered to handle a variety of materials, including leather, vinyl, and specialized fabrics that are commonly used in vehicles. These machines are built for durability, as they need to sew through multiple layers of thick materials while maintaining precise stitch quality. The average automobile can have intricate stitching designs, which require high-speed and accurate sewing machines to ensure a flawless finish.
