Blank Cotton Jersey T-Shirts and Tank Tops: What to Specify Before the First Order
Blank cotton jersey tees and vests turn on four coupled numbers: finished weight (150–170 gsm mainstream; 180 gsm the single-jersey ceiling; cotton interlock carrying 200), yarn count (28s to 32s combed) and stitch length, neckline construction, and dimensional change named with its test method. A ribbed collar recovers after washing; a self-fabric bound neck does not. A reliable supplier quotes stitch length, not adjectives.

Period Panties Manufacturing: Layer Construction, Absorbency and What to Specify (2026)
Period panties normally run on a minimum of around 2,000 pieces per style and colour. Technically they are a layered construction rather than a single fabric: a body-facing layer, an absorbent core and a barrier layer, plus the gusset that joins them. Each layer is a separate specification item, and the stack — not the fibre name — is what the programme rests on.

Underwear Fabric Guide: Modal vs Cotton vs Bamboo (2026 Buyer’s Guide)
Pick fabric from your price point, not the buzzword. Combed cotton, 160 to 200 gsm, with five per cent spandex is the lowest-risk choice for basics and survives washing. Good modal, named at fibre level, earns its premium on women's lines; cheap modal pills within a few washes. Bamboo is usually viscose, so the eco story holds only if the mill documents its process. Unitex Underwear specs fabric, weight and blend to your market.
What Is Recycled Cotton? Is It Cheaper Than Regular Cotton? – A Sustainable Material Guide Every Underwear Sourcing Professional Must Read
Recycled cotton pays off on the fibre bill and less so on the yarn bill. Textile waste is far cheaper than farmed cotton, but shorter fibres spin slower, need more sorting and are usually blended to hold strength, so finished yarn can land level with virgin cotton or fifteen to thirty-five per cent above it. Unitex Underwear blends it for underwear rather than selling the label alone.

How Can Underwear Factories Deal With the Problem of Fabric Color Difference?
Colour difference is caught before it reaches the line, not after. The work starts with yarn from one batch and origin, dyes chosen for the fibre, and tight control of temperature, time and pH; then cutting keeps shades apart so one garment never mixes two dye lots. A retained standard swatch settles disputes. Unitex Underwear agrees the tolerance in writing before bulk.

Knit vs. Woven Pajama Fabric: A Complete Seasonal Comfort Guide
Knit is one yarn looped back into itself, so it stretches, feels soft and traps still air for warmth. Woven crosses warp and weft at right angles, giving a crisp hand and the non-cling drape that keeps summer sleepwear off damp skin. That is the decision: warm-weather lines on lightweight woven cotton such as poplin or seersucker, cold-weather lines on French terry, rib or interlock. Unitex Underwear matches structure to season before fixing price.

Uncovering the Secrets of Men’s Underwear Materials
Men's underwear materials differ in hand, recovery, moisture behaviour and cost rather than in a ranking. Cotton is the volume base, modal offers a softer hand with better shape retention, and bamboo moves moisture well with a sustainability claim attached — the choice follows the market rather than a fibre preference.

2026 Ultimate Guide to Sportswear & Sports Underwear Fabrics: How to Choose Breathable, Non-Sticky Performance Materials?
Five fibres carry the sports category: polyester for wicking and cost, nylon for softness and durability, polypropylene for moisture transport, cotton for daily comfort, and merino for premium temperature regulation. The choice follows the support level and the activity rather than the fibre name, and each trades drying speed against hand-feel.

2026 Summer Underwear Guide: How to Choose Perfect Underwear for Hot Weather
Summer underwear is specified on three variables: fabric weight, elastane content and the compliance file. A 140–150 g/m² single jersey behaves differently from 180 g/m² in heat and humidity, in drape and in how it looks after ten washes. A 5–10% elastane blend holds shape through repeated washing where pure cotton does not. And the print, dye and trims are part of the tested article, so the test report has to cover the whole garment.

Bacterial cellulose is a lab-grown textile with three properties relevant to underwear: it holds natural moisture above 90%, which removes the static that builds in dry winter conditions; it degrades in soil in roughly 28 days without leaving microplastics; and it does not pill. The constraint is cost — the technology sits at the research-to-pilot stage, with a projected cost reduction of around 60% over three to five years.

Knit Underwear Color Fading & Color Fastness: 6 Quality Control Checkpoints from a Professional Supplier
Colour fastness ranks among the top three quality complaints in the category, behind sizing deviations and seam failures. Knit underwear is more exposed because the structure has more surface and more open edges, and because dye uptake varies between the body fabric and the trims. The test has to run on the actual construction rather than on the base cloth.
