A Guide to Garment Manufacturing Processes: Advantages, Disadvantages & Fabric Applications

From LuopeiTa Clothes Factory

At Luopeita Clothes Factory, we believe that the beauty of a garment lies in its craftsmanship. The manufacturing process chosen for a clothing item significantly impacts its aesthetics, durability, comfort, and cost. This guide details some of the key techniques we employ, highlighting the pros, cons, and ideal fabric choices for each to help our clients make informed decisions.

1. Flatlock Stitching (Flat Seam)

Description: This technique uses a specialized sewing machine (a flatlock machine) to create a seam where the fabric edges are butted together and joined by a zigzag stitch, rather than overlapping. It results in a flat, smooth seam, often with a decorative ladder-like effect on the reverse side.

• Advantages:

  • Seamless Comfort: The completely flat seam eliminates bulk and friction, making it ideal for areas that contact the skin directly, like the sides of t-shirts or underwear.

  • Durability: The stitch structure is strong and allows for significant stretch without popping stitches.

  • Moisture Management: The flat profile doesn't trap moisture, perfect for activewear.

  • Aesthetic Appeal: The decorative "ladder" stitch is often used as a design feature on sportswear and casual garments.

• Disadvantages:

  • Cost: Requires specialized machinery and more skilled operators than a basic overlook stitch.

  • Fabric Limitations: Not suitable for woven, non-stretch fabrics as the seam can gap open.

  • Complexity: More time-consuming to set up and sew than a standard seam.

• Ideal Fabric Types:

  • Knits: Jersey, interlock, rib knit, French terry.

  • Stretch Fabrics: Elastane blends, stretch mesh, performance fabrics.

  • Commonly Used For: Activewear, t-shirts, leggings, underwear, athleisure.

2. Overlock Stitching (Serging)

Description: This is the most common seam finish in mass-produced clothing. An overlock machine trims the fabric edge and simultaneously encases it with thread, preventing fraying. It creates a durable, flexible, and neat edge.

• Advantages:

  • Efficiency & Speed: Extremely fast, making it cost-effective for high-volume production.

  • Durability: Excellent for preventing fabric fraying, increasing the garment's lifespan.

  • Stretch: The stitch has natural give, making it suitable for knit fabrics.

  • Neat Finish: Provides a professional, clean finish on the inside of the garment.

• Disadvantages:

  • Bulk: Can create a slightly bulky seam compared to a flatlock, which might cause irritation in high-sensitivity areas.

  • Less Refined Look: While functional, it is not considered a high-end finish for visible seams on delicate garments.

  • Not for Wovens (Alone): While it finishes the edge, a separate straight stitch is often needed for the main seam strength on wovens.

• Ideal Fabric Types:

  • Almost all fabrics, but most notably:

  • Knits: All types (jersey, ponte, sweater knits).

  • Wovens: Light to medium-weight fabrics like cotton, linen, rayon (primarily for seam finishing).

  • Commonly Used For: T-shirts, sweatshirts, pajamas, dresses, and for finishing inner seams on virtually all garment types.

3. Coverstitch

Description: This process uses two or more needles to create parallel rows of straight stitching on the top side and a serger-like looper thread on the underside. It is primarily used for hemming and topstitching on knit garments.

• Advantages:

  • Professional Hems: Creates a clean, professional hem on knits that must stretch without breaking the thread (e.g., t-shirt bottoms and cuffs).

  • Decorative Topstitching: The parallel rows offer a sporty, decorative look for details on necklines and sleeves.

  • Flat and Stretchy: The resulting hem is flat and has excellent recovery.

  • Durability: Very secure and durable stitch.

• Disadvantages:

  • Specialized Machine: Requires a dedicated coverstitch machine, which is a significant investment.

  • Complex Setup: Threading and adjusting the machine is more complex than a standard sewing machine.

  • Limited Application: Used almost exclusively for hemming and topstitching, not for constructing main seams.

• Ideal Fabric Types:

  • Knit Fabrics: Jersey, interlock, ponte di roma, sweatshirt fleece.

  • Stretch Fabrics: Any fabric with significant spandex/elastane content.

  • Commonly Used For: Hemming t-shirts, leggings, athletic jerseys, neckline bindings, and decorative details.

4. Silkscreen Printing

Description: A popular printing technique where ink is pressed through a fine mesh screen onto the fabric. Each color in the design requires a separate screen.

• Advantages:

  • Vibrant Colors: Can lay down a thick layer of ink for opaque, vibrant colors on dark garments.

  • Durability: High-quality plastisol inks are very durable and withstand many washes.

  • Cost-Effective for Bulk: Unit cost becomes very low for large production runs.

  • Versatility: Can be used on a wide range of fabric colors and types.

• Disadvantages:

  • High Setup Cost: Creating screens for each color is expensive, making small runs uneconomical.

  • Stiff Hand Feel: The ink can leave a noticeable texture or stiff feel on the fabric, especially with large, solid designs.

  • Not for Complex Designs: Designs with many colors or photorealistic details require many screens, increasing cost and complexity.

  • Environmental Impact: Traditional plastisol inks are PVC-based and not eco-friendly (though water-based alternatives exist).

• Ideal Fabric Types:

  • Cotton & Cotton Blends: The best results are achieved on 100% cotton.

  • Polyester: Requires special inks and pretreatment for good adhesion.

  • Commonly Used For: T-shirts, hoodies, tote bags, posters, and any garment requiring bold, graphic designs.

5. Embroidery

Description: The art of decorating fabric with needle and thread (or yarn) using automated multi-head machines. The design is digitized first and then stitched onto the garment.

• Advantages:

  • Premium & Luxurious Feel: Adds a high-end, textured, and professional look to garments.

  • Extreme Durability: Excellent wash fastness; the design will last the lifetime of the garment.

  • Tactile Texture: Creates a raised, three-dimensional effect that is visually and physically distinctive.

  • Brand Prestige: Ideal for company logos, insignias, and details that require a premium appearance.

• Disadvantages:

  • High Cost: Digitizing and setup are expensive. The stitching process is slower than printing.

  • Not for Large Areas: Covering large areas is costly, heavy, and can make the fabric stiff and uncomfortable.

  • Fabric Limitations: Can cause puckering on very lightweight, thin, or stretchy fabrics if not stabilized correctly.

  • Backing residue: Requires a stabilizer (backing) behind the fabric, which must be torn away, sometimes leaving a slight residue.

• Ideal Fabric Types:

  • Medium to Heavyweight Fabrics: Denim, twill, canvas, jackets, polo shirt pique, corduroy.

  • Stable Knits: Polo shirt fabric, thicker sweatshirt fleece.

  • Fleece & Terrycloth.

  • Commonly Used For: Brand logos on caps, polo shirts, jackets, uniforms, and high-end decorative elements.
