Selvage Edge Formation Mechanisms: How Machines Make A Selvage Edge
When it comes to creating a selvage edge, a crucial process that enables the formation of a secure, self-finish seam on woven fabrics, there are several key mechanisms in play. The selvage edge is formed through a combination of the interlock stitch, thread selection, and tension control.
Interlock Stitch Formation
The interlock stitch, often referred to as the “edge stitch,” is a fundamental component of the selvage edge. It involves a continuous loop of thread that interlocks the warp yarns to create a secure finish on the fabric’s selvage. To form the interlock stitch, the sewing machine uses a specialized hook or needle, which creates a loop in the thread as the fabric moves below the needle. As the fabric advances, the loop is formed on the underside of the fabric, trapping the warp yarns in place and preventing fraying.
Threads Used for Selvage Edging
Selvage edges can be created using various types of threads, including:
“For high-quality selvage edges, it’s often recommended to use a heavier-weight thread, such as cotton or polyester, with a high number of threads per inch.”
Some common threads used for selvage edging include:
- Cotton thread: Known for its breathability and ability to hold a tight stitch, cotton thread is a popular choice for selvage edging.
- Polyester thread: Offers excellent durability and resistance to wear and tear, making it ideal for high-traffic areas or heavy-duty applications.
- Cotton-polyester blend: Combines the benefits of both cotton and polyester, providing a strong, durable stitch while allowing for breathability.
Effect of Thread Tension on Selvage Edge Formation, How machines make a selvage edge
Thread tension plays a critical role in the formation of a high-quality selvage edge. If the thread is too loose, the stitch may be uneven or prone to fraying, while an overly tight thread can lead to puckering or distortion of the fabric. Achieving the optimal thread tension is crucial for creating a smooth, secure selvage edge.
Manual vs. Automated Selvage Edge Creation
Both manual and automated methods can be used to create selvage edges, each with its own set of advantages and disadvantages.
