- Fiber composition (cotton, recycled, elastane %, etc.)<\/li>\n
- Weight (oz\/yd\u00b2 or gsm; specify washed vs. loomstate)<\/li>\n
- Weave \u2013 e.g., 3\/1 RHT (right-hand twill), 2\/1 LHT (left-hand twill), broken twill, plain, jacquard<\/li>\n
- Stretch % and recovery rate, if any stretch is needed<\/li>\n
- Dyeing method \u2013 rope or sheet dyed, number of indigo dips or target shade code<\/li>\n
- Finish \u2013 sanforized (pre-shrunk), resin, softener; this determines shrinkage and hand feel<\/li>\n
- Cuttable width (cm or inches of usable fabric, not loom width)<\/li>\n
- Intended garment \u2013 jeans, jacket, workwear; that drives strength and drape requirements<\/li>\n<\/ul>\n

<\/p>\nSampling & Quality Control Process<\/h2>\n
- \n
- Fabric swatch<\/strong> \u2013 initial hand feel and weave check. No washing yet.<\/li>\n
- Sample yardage (5\u201315 m)<\/strong> \u2013 wash test for shrinkage, colorfastness, and stretch recovery.<\/li>\n
- Lab-dip or shade-band<\/strong> \u2013 approve a master shade that will guide bulk production.<\/li>\n
- Pre-production sample (50\u2013100 m)<\/strong> \u2013 confirm shade, width, weight, and hand feel on the actual production line.<\/li>\n
- Bulk testing<\/strong> \u2013 pull random roll samples; release payment only when results fall within tolerances.<\/li>\n<\/ol>\n

<\/p>\nKey tests: shrinkage rate (max % after standard laundry), stretch recovery, crocking (wet and dry), tensile\/tear strength.<\/p>\n
Avoid These Sourcing Mistakes<\/h2>\n
- \n
- Asking for \u201cdenim\u201d without weight, weave, or composition \u2013 that forces guesswork.<\/li>\n
- Approving a hand-feel swatch without testing a washed sample yardage.<\/li>\n
- Skipping a shade tolerance \u2013 indigo shifts between dip lots.<\/li>\n
- Not verifying the supplier is a real mill; request a live video of the dyeing\/weaving floor.<\/li>\n
- Ignoring how your garment wash process impacts final color and strength.<\/li>\n<\/ul>\n

<\/p>\nEssential Questions for Suppliers<\/h2>\n
- \n
- \u201cCan you share the full construction: yarn count, weave, finish, and weight details?\u201d<\/li>\n
- \u201cIs this fabric produced in-house or sourced? How do you maintain shade consistency across lots?\u201d<\/li>\n
- \u201cMOQ per color and total order for this construction \u2013 is it stock or custom?\u201d<\/li>\n
- \u201cProvide sample stages (hanger, yardage, lab-dip, pre-production) with lead times and costs.\u201d<\/li>\n
- \u201cSupply a recent test report for shrinkage, crocking, tensile strength, and stretch recovery \u2013 tested after home laundry.\u201d<\/li>\n<\/ol>\n

<\/p>\nPreguntas frecuentes<\/h2>\n
How to verify sustainable denim claims?<\/strong> Get certificate numbers and scope documents (GRS, OCS, OEKO-TEX) that cover that exact fabric. A generic mill certification doesn\u2019t prove the cloth meets the standard.<\/p>\n
![\"Denim](\"https:\/\/lydenim.com\/wp-content\/uploads\/2026\/06\/2b0d066e084122122cefcd6d456cbac3c22b876042cd6a0c38adea612a52db4c-1.webp\")
<\/p>\nHow to tell if a supplier is a real mill?<\/strong> Ask for a live video of the dyeing and weaving floor, plus a pre-production sample traceable to their production line. Trading desks only show stock shelves.<\/p>\n
Why does small-batch cost more?<\/strong> Setup and sampling are fixed costs. Shorter runs raise unit price. Stock fabric can lower cost but limits your choices \u2013 sometimes significantly.<\/p>\n
What\u2019s reasonable shrinkage for sanforized denim?<\/strong> Mills usually guarantee \u22643% residual shrinkage after home laundry, but your garment wash can push that higher. Always test under your own wash conditions.<\/p>\n
Choose denim mills by technical capability, sampling rigor, and transparent communication \u2013 not the lowest quote. Define your specs, demand production-line samples, and test shrinkage and crocking yourself before committing.<\/p>\n
