As a professional apparel manufacturer, having a profound understanding of garment accessories is absolutely essential. Just like an exceptional chef needs to know the varieties and characteristics of their spices to create a masterpiece, a garment manufacturer relies on the perfect accessories to bring a design to life.
Garment accessories come in many forms, but they can generally be divided into the following 7 core categories:
-
Linings
-
Interlinings & Pads
-
Fillings
-
Threads & Tapes
-
Fastenings & Closures
-
Decorative Materials
-
Labels & Tags
1. Garment Linings
Lining is the material used for the inner layer of a garment. Common materials include polyester taffeta, nylon taffeta, flannel, and various cotton or T/C (polyester/cotton) blends.
The Main Functions of Garment Lining:
-
Makes the garment smooth, easy to put on/take off, and comfortable to wear.
-
Reduces friction between the outer fabric and undergarments, protecting the main fabric.
-
Adds thickness to increase thermal insulation.
-
Helps the garment maintain a smooth and crisp shape.
-
Elevates the overall quality and grade of the garment.
-
For padded garments, it prevents the filling from leaking. For leather jackets, it keeps the leather clean and pristine.
Types of Lining Craftsmanship (Common in Outerwear):
-
Fully Detachable Lining (Removable): Connected by fasteners, making it easy to remove and wash.
-
Fully Attached Lining (Fixed): Sewn permanently into the garment; cannot be removed (the most common type).
-
Half Lining: Only the upper half of the garment is lined.
Key Considerations for Designers:
-
Compatibility: The lining’s performance (shrinkage rate, heat resistance, washability, strength, thickness, and weight) must match the main fabric.
-
Color Coordination: The lining color should harmonize with the main fabric and generally should not be darker than the outer shell.
-
Durability: It must be smooth, durable, anti-pilling, and have excellent colorfastness.
Main Categories of Lining Materials:
-
Cotton: Excellent moisture absorption, breathable, warm, and anti-static. Drawbacks: poor elasticity and less smooth. Ideal for kidswear and casual jackets.
-
Silk: Highly breathable, lightweight, smooth, and anti-static. Drawbacks: lower tensile strength, prone to yarn slippage, and harder to sew. Used for high-end garments like fur coats and pure wool suits.
-
Synthetic Fibers (Chemical Fibers): High strength, durable, wrinkle-resistant, dimensionally stable, and moth-proof. Drawbacks: prone to static and less breathable. Widely used in mid-to-low-end garments due to affordability.
-
Blends: Combines the benefits of natural and synthetic fibers. Excellent for mid-to-high-end apparel.
-
Fur & Woolen: Unmatched warmth and comfort. Primarily used in winter coats and leather jackets, though more expensive.
-
Warp-Knitted Mesh: Available in circular, diamond, or shuttle shapes. Widely used as lining for sportswear.
Pro Tip: Common silk/taffeta linings include 170T, 190T, 210T, and 230T. Fleece linings (single-sided, double-sided, warp-knitted) are usually measured by weight, typically ranging from 120-160 GSM. Pocketing fabrics are also classified as linings, commonly using T/C 45×45, 65×35, 96×72, and 133×72. Critical Test Metrics: Shrinkage and colorfastness. For down jackets, high-density or coated linings must be used to prevent down leakage.
2. Interlinings & Pads
This category includes both interlinings (fusible/sew-in) and shoulder/chest pads. Interlinings are applied to collars, cuffs, pockets, waistbands, hems, and suit chests. Fusible interlinings contain adhesive dots, while others are woven, knitted, or non-woven.
The Role of Interlining: Often called the “skeleton” of a garment, it enhances strength, maintains structural shape and dimensional stability, improves wrinkle resistance, and makes sewing operations easier, resulting in a full, aesthetically pleasing silhouette.
-
Interlining: Woven, knitted, or non-woven fabrics with adhesive (Fusible Interlining) applied to specific areas.
-
Pads: Shoulder pads and chest canvases used to build volume and structure (usually non-adhesive).
Key Considerations for Designers:
-
Match the interlining’s thickness, weight, drape, and color with the main fabric.
-
Consider the structural needs of the design.
-
Account for aftercare: ensure the interlining’s dimensional stability matches the fabric during washing or dry cleaning.
-
Crucial Note on Washing: Always test the interlining with the main fabric before bulk production. Otherwise, special washes may cause bubbling, peeling, or delamination.
3. Fastenings & Closures
These serve both functional and decorative purposes, including buttons, hooks, loops, zippers, and Velcro.
Buttons:
-
By Size: Measured in Lignes (L). Formula: Diameter (mm) = Ligne x 0.635. (e.g., 14L, 16L, 18L, 20L).
-
By Material: Natural (shell, coconut, wood) vs. Chemical (resin, plastic, urea, electroplated).
-
By Structure (Resin): Rod-shaped blanks (pearlescent, patterned) vs. Plate-shaped blanks (corrugated, striped).
-
By Holes: Shank buttons (hidden hole on the back) vs. Sew-through buttons (2-hole, 4-hole).
-
By Finish: Glossy, semi-gloss, matte.
Zippers: Zippers are categorized by material (Metal, Resin, Nylon/Invisible) and structure (Closed-end, Open-end, Two-way open-end). Sizes range from #3 to #10 (the larger the number, the wider the teeth).
Key Considerations for Zippers:
-
Are all components color-matched without stains?
-
Does the slider auto-lock properly?
-
Are metal zippers coated with anti-oxidation protection (clear lacquer)?
-
Are nylon zippers needle-detector compliant?
-
Note: Always instruct laundries to wash garments with zippers fully closed to prevent tooth damage or color fading.
4. Threads & Tapes
Threads: Used for stitching and decoration. Includes natural fibers (100% cotton, silk), synthetic fibers (polyester, nylon, acrylic), and blends (poly-cotton, core-spun). Rule of thumb: For the same ply count, the lower the thread count number, the thicker the yarn.
Tapes & Ribbons:
-
Elastic Tape: Made with rubber; used for waistbands and cuffs.
-
Ribbing (Knit): Made of cotton, wool, or synthetics; used for necklines, cuffs, and hems.
-
Webbing/Woven Tapes: Used for plackets and necklines. Available in plain, twill, satin, and jacquard weaves.
5. Fillings / Fillers
Placed between the shell and lining for thermal insulation or 3D embroidery padding.
-
Cotton/Synthetic Batting: Prone to deformation after washing if low quality. Washable cotton and spray-bonded cotton are industry standards.
-
Down & Feathers (Goose/Duck): Unmatched warmth and loftiness, but requires strict sterilization and anti-leakage fabrics.
6. Decorative Materials
Includes lace, tassels, sequins, beads, and appliques to increase the aesthetic and added value of the garment.
7. Labels & Tags
Includes brand woven labels, size tags, care labels, hangtags, leather patches, and origin tags. Materials range from cotton and satin to plastic and leather.
10 Crucial Points for Sourcing Garment Accessories (Manufacturer’s Guide)
For smooth production, apparel manufacturers must verify the following details when sourcing accessories:
-
Linings: Confirm composition, density, quality, width, and color matching. Calculate precise consumption rates. For cotton, check the warp/weft shrinkage rates.
-
Fillings: Determine the exact weight (GSM) required per garment. Specify whether the filling is machine-quilted or hand-stuffed (hand-stuffing requires precise weighing per piece and incurs higher labor costs).
-
Interlinings: Check weight, thickness, and color. Use heavy interlinings for flannel and soft ones for silk. Ensure they withstand the garment’s specific washing requirements.
-
Pocketing Bags: Confirm composition (e.g., T/C 65/35), density, width, color, shrinkage, and whether the pocket edges will be bound or overlocked.
-
Threads: Confirm composition, thickness, ply, and color match. Calculate required yardage based on SPI (Stitches Per Inch, e.g., 7 SPI) and determine dyeing lead times.
-
Buttons: Confirm composition, shape, Ligne size, custom engraving, color, and whether they need to pass needle detector tests. Ask the factory for mold fees if custom.
-
Zippers: Confirm the brand (e.g., YKK, SBS), material, size, teeth type, tape color, and slider lock type. Calculate exact lengths (e.g., Placket length 10cm – 1cm = 9cm zipper).
-
Woven/Care Labels: Confirm material, text accuracy, dimensions, color, and exact sewing placement.
-
Hangtags: Confirm material, double-sided text, dimensions, placement, and whether they are attached by machine or hand (affects labor quotes).
-
Decorative Trims: Confirm trim type, composition, width, color, text, and exact sewing placement on the garment.
FAQ
What are the main categories of garment accessories?
Garment accessories are generally divided into 7 categories: linings, interlinings/pads, fillings, threads/tapes, fastenings/closures (like zippers and buttons), decorative materials, and labels/tags.
Why is the lining important in garment manufacturing?
Lining makes a garment comfortable and easy to wear, reduces friction to protect the outer fabric, adds thermal insulation, maintains the garment’s structure, and conceals internal seams or fillings.
What is the difference between woven and non-woven interlining?
Woven interlining is made from interlaced yarns (like standard fabric) offering flexibility and strength, whereas non-woven interlining is made by pressing chemical fibers together. Both can be coated with adhesive to become fusible interlinings.
How do you measure the size of a button?
Button sizes are measured in Lignes (L). You can calculate the diameter in millimeters using the formula: Diameter (mm) = Ligne model × 0.635. For example, a 20L button is 12.7mm in diameter.
What should I consider when choosing pocketing fabric?
You must consider the fabric composition (usually T/C blends like 65/35), density, color coordination with the main fabric, shrinkage rates, and the required construction method (bound or overlocked).
How do I ensure my metal zippers aren’t damaged during garment washing?
Metal zippers should be coated with an anti-oxidation clear lacquer. Additionally, always instruct the washing facility to wash the garments with the zippers fully closed to prevent tooth damage and color fading.
Why must interlinings be tested before bulk production?
Interlinings must be tested with the specific main fabric to ensure compatibility. If not tested, the interlining might bubble, peel, or separate from the fabric during post-production washing or dry cleaning.
