What is a Long Upholstery Needle?

Conclusion

1. Efficiency One of the primary advantages of using a double needle sewing machine is the time-saving aspect. By sewing two lines simultaneously, operators can complete tasks faster than they would with a single needle machine, maximizing productivity, especially in large-scale operations.

3. Needle Compatibility Ensure your sewing machine can accommodate leather needles, which have a wedge-shaped point to penetrate the material without tearing it. These needles come in various sizes; a thicker needle is necessary for heavier hides.

A lock stitch is created by interlocking two threads a top thread and a bottom thread, which is drawn from the bobbin beneath the fabric. This stitching technique is prevalent in home and industrial sewing machines, primarily due to its robustness and capability to produce a neat and professional finish. The lock stitch is characterized by its straight line and tight, even formation, making it ideal for various sewing tasks.

One of the advantages of chain stitch sewing is its durability. The stitch tends to hold up well under stress and strain, which is why it is commonly used in heavy-duty applications like upholstery and canvas. However, it is important to note that while chain stitches offer flexibility and durability, they can be more susceptible to unraveling compared to locked stitches. This means that careful handling and proper finishing techniques, such as backstitching or knotting, are vital to ensuring the longevity of the seams.
