The machine needle is one of the most important components of a sewing machine. The chapter "Machine Needle" from the book "Basic Sewing Machine" explains its structure, types, functions, and proper selection. The needle plays a key role in forming stitches by carrying the thread through the fabric and interlocking it with the bobbin thread.

Proper selection and maintenance of the machine needle are essential for achieving high-quality stitching and preventing damage to fabric and machine parts.

Structure of a Machine Needle

A sewing machine needle consists of several parts, each having a specific function.

• Shank: The upper part that fits into the needle holder
• Shaft: The main body of the needle
• Eye: The hole through which thread passes
• Point: The sharp tip that pierces the fabric
• Groove: Guides the thread along the needle
• Scarf: A small indentation that helps in stitch formation

Each part contributes to smooth and efficient stitching.

Functions of Machine Needle

The machine needle performs several important functions in sewing.

• Pierces the fabric
• Carries the upper thread
• Forms loop for stitch formation
• Works with bobbin to create stitches

It is essential for proper stitch formation and fabric handling.
