Fabric Guide

Cotton Pajamas — Fabric Guide for Sleepwear Brands

The sleepwear default — breathable, easy to print, easy for customers to care for.

What it is

Cotton is a natural cellulose fibre spun into yarn and then either woven or knitted. For sleepwear it is the reference point: when a buyer says “make it comfortable and easy to care for”, cotton is usually the answer that needs the least explaining to the end customer.

The word “cotton” on its own does not describe a fabric, though. A cotton poplin, a brushed cotton flannel and a cotton jersey behave completely differently in wear, in the sewing room and on the shrinkage report. What you are actually choosing is a construction — and that decision changes the pattern, the seam type and the price more than the fibre does.

Where it fits commercially

Cotton is the safe centre of a sleepwear range. It sells year-round, it photographs honestly, and customers already know how to wash it. Its trade-off is against the silky, fluid handle of modal or satin — cotton looks and feels like a well-made shirt, not like lingerie.

If your collection needs both, the usual split is cotton for the classic button-up sets and men’s styles, and a cellulosic or satin for the women’s drapey pieces.

What to confirm before bulk

Washed shrinkage, measured on your approved sample, not quoted from a spec sheet
Whether the print method affects hand feel enough to change your product description
Pattern matching rules if you are using a check or stripe
Whether the fabric is pre-shrunk (mercerised, compacted, sanforised) and how

Properties

How it behaves

Fibre type: 100% cotton, or cotton blended with a small percentage of elastane for knits
Construction: Available as woven (poplin, twill, flannel) and knit (jersey, interlock, rib)
Weight: Woven pajama fabrics typically sit in a light-to-mid shirting range; knits are chosen by GSM. Confirm the exact weight on your approved sample rather than by name — "cotton poplin" covers a wide range.
Hand feel: Dry, matte and slightly crisp when woven; soft and relaxed when knit. Softens noticeably after the first few washes.
Stretch: None in plain wovens. Knits stretch mechanically; add 3–5% elastane when a body-skimming fit is needed.
Drape: Structured rather than fluid. Holds a shape — good for classic notch-collar sets, less suited to a liquid, poured look.
Breathability: High. Absorbs moisture rather than repelling it, which is why it remains the default for year-round sleepwear.

Production Notes

What to plan for

The practical consequences of choosing this fabric — the things that decide whether a bulk order goes smoothly.

Shrinkage considerations: Cotton shrinks. This is normal and manageable, not a defect — the fabric is pre-shrunk or compacted before cutting, and the pattern carries a shrinkage allowance. Always confirm shrinkage on a washed sample before approving bulk.
Printing & dyeing: Takes reactive printing and yarn-dyed work well, with strong colour saturation. Pigment printing is cheaper but sits on the surface and can stiffen the hand feel — check this on the sample if softness matters to your brand.
Sampling considerations: Ask for the sample to be washed once before fit approval. Cotton fit judged on an unwashed sample is not the fit your customer receives.
Production considerations: Widely available, so lead time is usually driven by dyeing and printing rather than by greige fabric supply. Yarn-dyed checks and stripes need pattern matching at cutting, which affects consumption.

FAQ

Fabric questions we get asked

How much does a pajama sample cost?

Sample cost depends on the style, fabric and customization (printing, embroidery, special trims). We confirm the exact sample fee per project before sampling starts — share your design through the quote form for a precise figure.

How long does sampling take?

Sampling time depends on style complexity, fabric availability and the number of revision rounds. We confirm a sampling timeline with each sample order and keep you updated through development.

Can I use my own pajama design?

Yes. Send a tech pack, reference sample or reference photos and we handle pattern development, grading and sampling to your design. Your designs stay confidential to your project.

Will my fit sample be washed before I approve it?

Yes — we launder fit samples before sending them. Cotton shrinks, knits relax and viscose can distort, so a sample approved unwashed is not the garment your customer receives. Approving fit on a washed sample removes the most common cause of bulk fit complaints.

Can you source custom fabrics?

Yes. Beyond stock cotton, modal, satin, jersey, flannel and viscose options, we source custom blends, custom-dyed colors and custom prints. Custom-developed fabrics carry higher minimums, which we confirm during quoting.

Can you match Pantone colors?

Yes. For custom-dyed fabrics we produce lab dips against your Pantone reference for approval before bulk dyeing, so the production color matches the approved standard.
