Chapter Three � The Contract Sewing Process
The contract sewing process is an industrial method for mass-producing a wide range of products for commercial and industrial use. The production of these products involves selecting components that are assembled and connected through sewing.
Contract sewing is a vital industry that supports large manufacturers in planning, developing, designing, and perfecting designs and procedures. The term "contract sewing" succinctly describes the process used to create sewn materials.
The Contract Sewing Process
Prototype and Design
The purpose of the prototype and design phase in contract sewing is to identify design flaws and develop methods for addressing them. This phase is based on the understanding that concepts and designs that appear promising on a computer may not always be practical in the production process. By catching errors and mistakes before moving into production, this phase helps save time and money.
Pattern
Unlike in the past when patterns were produced in print, modern contract and industrial sewing patterns are created using computer-aided design (CAD) programs. CAD allows for the creation of detailed 3D representations of garments, enabling designers to inspect every aspect and make edits by undoing or modifying elements while keeping the overall design intact.
A 3D sample created with CAD eliminates the need for physical samples for photo shoots or communication with buyers, as these can now be completed electronically. Instead of maintaining a backroom full of stored patterns, CAD allows for patterns to be stored online for future projects. Once the CAD rendering is finished, it can be easily passed on to a pattern maker or technical designer responsible for production.
The instructions on a pattern are customized for each product, as there is no single way to complete the process. As shown in the example below, instructions for contract sewing are often very brief. In many cases, no instructions are provided, and the specifics are left up to the contractor.
The electronic pattern process encompasses every aspect of product development. For clothing, it displays the cuts for each size and the methods for cutting. A crucial part of this process is determining the consumption of materials used in production, which influences the final cost.
Once the pattern is approved, it is sent to the pattern printer, a wide-format printer similar to a plotter used for printing blueprints. This step may vary among manufacturers; some print the pattern on heavy material that will be used in the cutting process.
Selection of Materials
Once production development is approved, the pattern undergoes marking and grading to determine the yield. This process helps calculate the amount of fabric needed for ribbons, lining, buttons, zippers, and other components. When the fabric arrives, a pre-production sample is made.
Before sending the fabric to production, it is inspected and preshrunk. While this may not apply to all contract sewing projects, inspecting and approving the materials—whether leather, polyester, vinyl, or another type—is a common practice. Ensuring that the materials are in good condition is crucial for producing a quality product.
Cutting
The cutting process involves laying the pattern out on the material to be cut. A very sharp, saw-like cutting tool then slices through several layers of fabric, following the guidelines of the pattern. While this method is used for manufacturing cloth or clothing items, it may vary for heavier materials such as leather or vinyl.
Computerized Cutting
Aside from hand cutting, a more efficient method is the automated high-ply cutting system designed specifically for cutting garments. Instructions for cutting are developed on a computer, which determines the optimal way to cut the fabric to minimize waste. In CNC (computer numerical control) style, these instructions are downloaded into the automated cutter to guide it through each cut.
Sewing
The process of sewing in contract or industrial settings differs significantly from a single person working at a sewing machine. In industrial sewing, the process resembles an assembly line. Each person performs a specific part of the assembly, with the item passing through a series of operations before being completed. Individual tasks may include sewing on a piece, adding a stitch or clip, or adjusting the positioning of the material.
Stitches
The proper selection of the type of stitch depends on the design of the final product and the material that is being secured.
Single Needle Lockstitch
The single needle lockstitch is the most common mechanical stitch, creating a smooth seam that does not pucker. It uses one needle and two threads that interlock within the fabric.
Double Needle Lockstitch
Double needle lockstitches are similar to single needle lockstitches but use two needles. This can sometimes result in puckering.
Zigzag
The zigzag stitch is similar to the lockstitch but produces a back-and-forth zigzag pattern.
Cover Stitch
A cover stitch is a double or triple stitch used for hemming knit fabrics and seams that stretch. On one side of the stitch, you see two parallel lines, while the underside features a zigzag pattern connecting the lines.
Bar Tack
A bar tack is a series of closely spaced stitches used to reinforce areas of a garment that are subjected to stress or wear.
Box X Stitch
The box X stitch is a square-shaped stitch with an X in the middle, commonly used for securing straps or handles to fabric bags.
Mauser Stitch
The Mauser stitch is a flatlock stitch created by a specialized machine that forms threads into a flat, interlocking pattern. It is known for being incredibly durable and comfortable, especially when placed against the skin.
Post Bed Lockstitch
The post bed lockstitch is performed by industrial sewing machines to stitch heavy-weight items such as car seats, furniture, and sporting goods.
Blind Stitch
The blind stitch is an invisible stitch used for hems or joining two pieces of fabric. It is hidden in the folds of the material and only becomes visible when the fabric is pulled apart.
The nine stitches listed above are just a sample of the various types used by contract sewing companies. The appropriate type of stitch is selected based on the needs of the material and product. Stitch selection is closely related to the dynamics of the material and its intended use.
