B2B Fabric Decision Guide
Direct Answer
Bamboo viscose is often selected for soft, stretch-focused sleepwear, while cotton offers broad construction and finishing options. The best choice depends on GSM, knit structure, opacity, stretch, recovery, shrinkage, printing, durability, climate and target retail positioning.
Use the table as a development brief, then validate the selected material through specifications, samples and any applicable testing. Results vary by supplier, lot, yarn, knit, GSM, finishing, print, garment construction and care.
| Decision factor | Bamboo viscose | Cotton |
|---|---|---|
| Hand Feel | Often smooth and fluid, depending on yarn, knit, GSM and finishing. | Ranges from crisp to soft depending on fiber, yarn, knit and finishing. |
| Breathability | Can support breathable sleepwear constructions; performance depends on the complete fabric and garment. | Can also support breathable sleepwear; weave or knit, weight and finishing influence the result. |
| Stretch | Frequently blended with spandex for fitted zippies and pajama sets. | Natural stretch varies by knit; spandex may be added when more recovery is required. |
| Recovery | Recovery depends on the knit, spandex percentage, finishing and stretch direction; approve the actual sample after wear and wash review. | Cotton knits may use spandex when stronger recovery is required; approve the actual construction and sample. |
| 180–200 GSM | Often reviewed for warm-climate or summer sets where drape and low bulk matter; light colors and stretch require opacity approval. | Can suit lightweight knit or woven sleepwear, subject to opacity, shrinkage, construction and intended season. |
| 200–220 GSM | A common development range for balanced kids and women’s programs, subject to knit, coverage, recovery and sample approval. | Can support midweight pajama programs; fiber grade, knit, finishing and target silhouette determine the result. |
| 220–230 GSM | May provide more coverage and a substantial hand for premium lounge sets, while heat, drape and recovery still require sample review. | May suit more substantial knit programs; confirm bulk, shrinkage, hand feel and seasonal positioning in the finished garment. |
| Opacity | Light colors, lower GSM and high stretch can reduce opacity; approve the actual fabric and fitted sample. | Opacity varies with yarn, knit or weave, color and weight; approve the actual fabric and garment. |
| Printing Options | Digital all-over printing can work well after artwork, scale, color and strike-off approval. | Pigment, reactive and digital routes may be considered based on fabric and order requirements. |
| Shrinkage Considerations | Pre-production wash and shrinkage review should be completed for the selected fabric and print. | Cotton commonly requires shrinkage planning; verify the actual lot and finished garment. |
| Durability | Wash life, recovery, colorfastness and seam performance depend on yarn, knit, finishing, care and construction. | Abrasion and wash performance vary by cotton quality, yarn, construction, finishing and care. |
| Pilling Considerations | Friction, yarn quality, knit, finishing and care can affect pilling; test the selected lot and sample. | Fiber length, yarn, surface construction, finishing and care can affect pilling; sample testing is still required. |
| Cost Factors | Fiber blend, GSM, print coverage, finishing, quantity and material availability influence cost. | Cotton grade, yarn, construction, dye or print method, quantity and market conditions influence cost. |
| Baby Sleepwear Suitability | May suit stretch zippies and sleepwear when construction, openings, trims, labels and testing are product-specific. | May suit knit or woven baby styles when the approved construction, measurements, labels and testing match the intended use. |
| Kids Pajama Suitability | Often considered for stretch two-piece sets; fit classification, measurements and applicable testing must be reviewed. | Supports knit or woven programs; fit, shrinkage, construction and applicable testing must be reviewed. |
| Women’s Pajama Suitability | Fluid drape and stretch blends can suit short sets, long sets, button-up styles or relaxed lounge silhouettes when opacity and recovery are approved. | Can support jersey, interlock, flannel or woven women’s pajama constructions across structured or relaxed silhouettes. |
| Warm Climate Suitability | Light-to-midweight constructions may suit warm climates, subject to opacity, moisture management and wearer preference. | Lightweight knits or wovens may also suit warm climates; construction and finishing matter more than fiber name alone. |
| Premium Brand Positioning | Can support premium-feel positioning when construction, finishing and documented claims justify it. | Can span value to premium positioning depending on cotton grade, yarn, construction and finish. |
Consider it when a brand wants a smooth hand feel, fluid drape, stretch blend and custom-print surface for fitted or lounge-oriented sleepwear. The finished product can be tested according to applicable standards, and test documentation may be available based on fabric and order requirements.
Consider cotton when the brand prefers familiar fiber positioning, a particular jersey or woven construction, a crisp or structured hand, or a supply and cost plan built around a specific cotton grade. Approve shrinkage, print, color and finished-garment performance.
Avoid absolute safety, chemical, residue, sensitivity or superiority claims that are not supported by product-specific evidence. These statements cannot be inferred from the bamboo or cotton source alone.
Use product-specific language: the selected fabric can be tested according to applicable standards; test documentation may be available based on fabric and order requirements; and the material may be suitable for premium sleepwear depending on construction and finishing.
Send your style, fit, season, GSM preference, artwork, size range, quantity, labels, packaging and target market.
