From Approved Specifications to Finished Underwear

Intivex Underwear manufactures men’s boxer briefs, boxers and trunks, women’s panties, boyshorts and high-waist briefs, plus selected seamless underwear. Our production process supports brands, importers, wholesalers and distributors sourcing OEM, private-label and recurring bulk orders.

The production route depends on garment construction. Cut-and-sew products move through pattern preparation, fabric cutting and sewing. Selected seamless styles begin with knitting and follow the additional operations required by the approved design. Both routes require confirmed materials, measurements, branding and packing instructions before production release.

Confirm the Sample and Order Details

Production starts with a review of the approved sample and written specification. Fabric, fit, measurements, waistband, colors, logo placement, labels and packaging must match the final order requirements.

Buyers should also confirm quantities by style, color and size. A total quantity without a size breakdown is insufficient for production planning. Outstanding changes should be resolved before materials are purchased or garments are cut.

Projects requiring development can begin through our OEM and private-label service, using a tech pack, physical reference sample or selected existing style.

Prepare Materials and Patterns

Fabric, yarn, elastic, waistbands, labels and other trims are reviewed against the confirmed specification. Material availability affects the schedule, particularly when custom colors, branded waistbands or special packaging require additional sourcing.

For cut-and-sew styles, patterns and size grading establish the garment dimensions across the ordered size range. Fabric stretch and the approved construction must be considered together. Changing the material after fit approval may require another sample review because the same pattern can produce a different result.

Spread, Cut or Knit

Cut-and-sew production uses fabric spreading and cutting to prepare garment panels. Material direction, panel shape and relevant print placement need to follow the approved construction. Cut components are organized for the next production stage.

Selected seamless underwear follows a knitting route using suitable yarns and confirmed garment requirements. Subsequent sewing, component attachment or finishing depends on the style. Seamless production is reviewed separately rather than treated as a direct substitute for a sewn design.

Sew and Assemble the Garment

During sewing and garment assembly, cut panels are joined and waistbands, elastic and other components are attached according to the design. Sewing operations vary with the garment structure and required seam finish.

First-piece approval checks the initial result before the construction is repeated across the batch. Stitching, panel alignment, key measurements and waistband attachment are reviewed against the approved reference. Branding and labels are incorporated at the appropriate production stage.

Inspect and Prepare for Packing

In-line checks help identify construction or measurement differences while production is underway. Finished garments are then checked for appearance, stitching, relevant dimensions, waistbands, branding and labels.

Our measurement and inspection process uses the approved specification as its reference. Required third-party testing should be discussed early so testing arrangements can be included in the order schedule.

Packing follows the confirmed style, color and size combinations. Individual bags, multi-packs, barcode labels and export-carton details are checked alongside order quantities.

Plan the Order Schedule

Sampling usually takes about 7–12 days. Bulk production usually takes about 30–45 days after sample and order confirmation, depending on materials, construction, size mix, branding, packaging and quantity.

Send your product specification, order breakdown, destination and delivery target for review. Production timing and shipment arrangements are confirmed separately so the manufacturing schedule is not confused with the final arrival date.
