Illustrative situation
A brand wants to start a pyjama line and cannot decide between a cotton jersey set, a woven poplin set and a modal blend. The founder wants something soft but also easy to care for and not too costly.
Main answer
A first sleepwear range works well with a small set of soft fabrics, such as cotton jersey, cotton woven or a modal blend, in simple two-piece sets with a relaxed fit, chosen for feel against skin, easy care and cost. If you add children’s sizes, check the CPSC sleepwear flammability rules before you design them.
Fabric options
Cotton jersey is soft, stretchy and easy to wear, but can pill or shrink if poorly finished. Woven cotton, such as poplin, has a crisper feel and a classic look and needs more careful sizing. Modal and other cellulosic blends feel smooth and drape well but may be pricier and need gentler care. The pajamas manufacturer page lists styles a factory can make.
Styles to start with
A short-sleeve top with shorts and a long-sleeve top with long trousers cover most seasons. A button front set is a classic, while a pullover set is simpler to make. Keep pockets and trims modest at first, and add a robe or loungewear later.
Fit and comfort
Sleepwear is usually relaxed, with elastic or drawcord waists and soft seams. Check that waistbands do not dig in, labels do not scratch, and trims do not cause irritation. Wear-test overnight, since comfort shows over hours.
Care and labels
Sleepwear is washed often, so choose care instructions customers will follow and test shrinkage on the finished set. The FTC requires care instructions on garments, and the fibre content label should match the fabric you used. Keep tags soft or print them on the garment for comfort.
Children’s sizes
CPSC regulates children’s sleepwear flammability in sizes 9 months to 14 through Parts 1615 and 1616, with exemptions for tight-fitting garments. Adult sleepwear is treated differently, so do not assume a kids’ version can copy the adult design.
Fact, recommendation, uncertainty
- Established fact
- CPSC regulates children’s sleepwear flammability for sizes 9 months to 14, with exemptions for tight-fitting garments, and adult sleepwear is treated differently.
- Recommendation
- Start with a few soft fabrics and simple sets, wear-test for comfort and check children’s rules before making kids’ sizes.
- Uncertainty
- The best fabric depends on climate, price point and customer, and rules change.

More perspectives from the team
Three further views on the same question, each by function. They add conditions and limits to the main answer; they are editorial notes, not customer reviews.
Sino Finetex Editorial Team Sourcing
Ask for fabric swatches and care instructions for each option and the minimum quantity per fabric. Limit: swatches do not show how a finished set will shrink and drape. Ask for shrinkage test results on each fabric before choosing, and keep them with the style file.
Sino Finetex Editorial Team Product selection
Choose one soft knit and one woven option and offer a few colours and prints. Limit: prints add minimums and make small orders harder. Offer one set that suits warm nights and one for cold.
Sino Finetex Editorial Team Quality & care
Wash the sample several times, check shrinkage and seam comfort, and wear it for a night. Limit: wear-testing by a few people may not show problems for sensitive skin. Check seams and elastic after washing.
