Quality control is another crucial aspect of shirt manufacturing that automatic sewing machines enhance. These machines are designed to deliver uniformity across all garments, ensuring that each shirt adheres to the same high standards. By eliminating the variability inherent in manual sewing, manufacturers can produce shirts that fit better and exhibit superior construction. This consistency not only boosts customer satisfaction but also strengthens brand reputation.

Heavy duty sewing needles are specially crafted to sew through multiple layers of fabric, heavy materials like denim, upholstery, leather, and canvas. The most notable difference between standard needles and heavy duty needles lies in their construction. Heavy duty needles have a thicker shaft and a larger eye, which allows them to accommodate thicker threads and withstand greater tension without bending or breaking. They come in various sizes, with the most commonly used sizes ranging from 90/14 to 110/18, indicating their increased strength and capacity for thicker materials.

Moreover, the twin needle sewing machine is ideal for topstitching, as it creates a visually appealing finish on the right side of the fabric while also providing reinforcement on the backside. When working with thicker fabrics or multiple layers, this feature proves invaluable. It not only adds to the durability of the stitches but also elevates the overall aesthetic of the finished product.
