The process breakdown of a basic shirt involves numerous steps, each requiring precision and expertise. From fabric selection and pattern making to cutting, assembling, and finishing, every stage plays a crucial role in determining the final product’s appeal and comfort.

Understanding the Sewing Section

In a garment manufacturing unit, the sewing section is akin to a bustling city center. It’s here that individual fabric pieces come together, taking on the form of a tangible, wearable garment. The sewing section’s operations are both complex and fascinating, requiring a blend of skill, precision, and effective management.

The sewing section is typically organized into several workstations or lines, each dedicated to different garment types or styles. For instance, one line might be dedicated to shirts, while another could focus on trousers. Each line comprises several sewing machines, each assigned to specific tasks or operations.

The sewing process begins with feeding – the process of feeding cut fabric pieces into the sewing line. Following the assembly line principle, each operator performs a specific operation and then passes the semi-finished garment to the next operator. For example, one operator might sew the shoulder seams, while the next might attach the collar.

An essential part of the sewing section’s operation is the ‘bundle system’. Cut pieces for a specific operation are bundled together and distributed along the line. Each bundle moves together through the entire process, maintaining the continuity and consistency of the production.

The sewing section’s efficiency is often measured by its ‘throughput’, i.e., the number of finished garments produced per hour. Maximizing throughput while maintaining quality is a constant challenge and requires effective line balancing, workforce training, and machinery maintenance.

Process Breakdown of Basic Shirt

Crafting a basic shirt involves a series of carefully orchestrated steps, each contributing to the overall quality and aesthetics of the final product. Here’s a detailed breakdown of the process:

1. Pattern Making: The journey of a basic shirt begins with pattern making. This involves creating the blueprint for each piece of the shirt, including the front panels, back panel, collar, sleeves, and cuffs. Patterns are created according to specific size and style specifications.
2. Cutting: Once the patterns are ready, they’re laid on the fabric, and the fabric is cut accordingly. This process requires precision to ensure that each piece is cut accurately and consistently.
3. Feeding: The cut pieces are then sorted and bundled together for each shirt, ready to be fed into the sewing line.
4. Sewing: This is the most complex part of the process, involving several different operations:
   • Shoulder Seams: The front and back pieces are sewn together at the shoulders.
   • Collar Making: The collar pieces are stitched together, turned right side out, and pressed.
   • Attaching the Collar: The collar is then sewn to the neckline of the shirt.
   • Sleeve Seams: The sleeves are sewn along the underarm seam, and cuffs are attached at the lower edge.
   • Attaching the Sleeves: The sleeves are then sewn to the armholes of the shirt.
   • Side Seams: The front and back pieces are sewn together along the side seams, integrating the sleeves.
   • Hemming: The bottom edge of the shirt is hemmed to give a clean finish.
   • Buttonholes and Buttons: Finally, buttonholes are made on the front panel and cuffs, and buttons are sewn in place.
5. Pressing: The completed shirt is then pressed to remove any wrinkles and give it a neat, finished look.
6. Quality Control: The final step involves a thorough quality check to ensure that there are no flaws in the garment. Any necessary corrections are made at this stage before the shirt is approved for shipping.
