Function of the Sewing Needle
The Context of Sewing Machines used in the Garment Industry, the Needle refers to a slender, pointed metal tool that is a fundamental component of sewing machines. The needle plays a crucial role in stitching fabric together by creating a series of interlocking loops with the thread.
Function of the Sewing Needle. Here are some key points about sewing machine needles:
- Function: The needle pierces the fabric and carries the upper thread through the fabric layers. It interacts with the bobbin thread to form stitches that secure fabric layers together.
Types: Sewing machine needles come in various types and sizes, each designed for specific fabrics and sewing tasks. Common types include universal needles, ballpoint needles (for knit fabrics), sharp needles (for woven fabrics), denim needles (for heavy fabrics like denim), and more specialized needles for embroidery and quilting.
Parts: A typical sewing machine needle consists of a shank (the top part that fits into the needle holder), a shaft (the middle part that penetrates the fabric), and a point (the tip of the needle that pierces the fabric). Needles also have a groove or channel to guide the thread.
Sizes: Needles are categorized by size numbers (e.g., 80/12, 90/14), where the first number represents the European size (diameter of the shaft) and the second number represents the American size (thickness of the needle). Different sizes accommodate different fabric weights and thread types.
Replacement: Needles should be replaced regularly to ensure clean, precise stitching and to prevent damage to fabrics and the sewing machine. Factors like fabric type, thread thickness, and sewing speed affect how often needles need to be changed.
Maintenance: Proper care includes using the correct needle type and size for the fabric being sewn, ensuring the needle is correctly inserted and aligned, and checking for damage or dullness. Needles should be inserted with the flat side facing the back of the machine.
Function of the Sewing Needle. The needle is a critical component that, along with the thread and bobbin, forms the basic elements of sewing. Choosing the right needle for the task and maintaining it properly ensures efficient and high-quality sewing in garment production.
