Manufacturing & Quality Control
Cutting, sewing, finishing, inspection and production management.
The Simple Production Process of Underwear
A pair of underwear is decided long before the sewing line runs: material and tooling are chosen, the body measurements are taken, the pattern is drawn and the pieces are cut. The silhouette then does the rest, with a classic brief cut from an isosceles triangle, a roomy leg on boxer briefs and a narrowed back on a thong. Unitex Underwear runs that sequence with partner workshops in Fujian.

The Underwear Production Process: From Design Concept to Container Shipment
A complete OEM underwear order runs about 16 weeks across five stages: pre-production covering design, sampling and material booking, production preparation, mass production, finishing and packing, then shipping quoted separately. Material procurement is the stage carrying the highest delay risk, and the choice between sea and air freight moves the promised delivery date more than any step inside the factory. Unitex Underwear manages those stages from Xiamen with dated outputs at each one.

Women’s Underwear Size Guide: Creating Inclusive Size Charts for Global Markets
Inclusive sizing in women's underwear is a grading project rather than a range extension: extending a band needs a re-graded set, because proportions change as the size moves away from the developed size. The practical consequence is that the extended sizes are developed rather than added.

Women’s Seamless Underwear: The Complete OEM Manufacturing Guide
Seamless underwear is knitted as a piece rather than cut and sewn, which removes the side seams and changes both the fit behaviour and the minimum structure. For an OEM programme the practical consequences are a different sampling route, a construction that cannot be adjusted by altering a seam, and a minimum that follows the knitting programme.
Explore the Ways for Dyeing and Printing Factories to Make the Hand-feel of Underwear Fabrics Soft and Comfortable
Fabric hand-feel is set by the finishing route rather than by the fibre: enzyme treatment for surface softness, mechanical treatment for physical softening, liquid ammonia for dimensional stability, alkaline de-weighting for drape, and functional finishing for performance. Each changes the fibre's behaviour, so the route belongs in the specification.
Why is Knitted Fabric More Suitable for Making Underwear?
Why is Knitted Fabric More Suitable for Making Underwear? Knitted fabric dominates underwear because of four advantages: natural multi-directional stretch (moves with the body), built-in breathability…

Dimensional Stability of Underwear Affected – Shrinkage Rate of Fabric
Dimensional change belongs to a specific fabric, cut and wash cycle, not to underwear in general. Specify length and width as two separate figures, name the wash and drying procedure from ISO 6330 and the measurement method from ISO 5077, then fix a pass or fail tolerance in the purchase order. Test the production fabric lot before cutting, because an AQL inspection will not catch a garment that shrinks one size.

How to Reduce the Cost of Underwear Products Without Sacrificing Quality
Five levers, worked in order: fabric consumption through the cutting plan, minimum consolidation through fewer colourways, simplification of cost that does not show, sea freight for the planned volume, and supplier integration. The specification is held fixed while the structure changes.
How to Reduce the Cost of Underwear Products
Cost reduction in underwear runs on four levers rather than one: material procurement, production technology, inventory management and the sales channel. Cutting material alone moves cost onto the parts of the programme that carry risk, which is why the lever order matters more than the size of any single cut.
Unitex Underwear Supplier – Safeguarding Your Quality Sleep
Sleepwear improves sleep on three variables — fabric breathability, seam and label comfort, and seasonal weight — all three fixed at the development stage, not after sampling. Unitex Underwear (Xiamen Unitex Trade Co., Ltd.) supplies OEM sleepwear programmes: cotton and bamboo for temperature regulation, modal or micro-modal where hand feel decides the spec, flat seams and tagless labels as standard, and weights matched to season from light nightgowns to polar fleece sets.
