Buying guide
Hospital bed sheet fabrics and thread counts explained
Quick answer: most hospital bed sheets are a cotton-polyester blend woven at T-130 to T-180, which is where hot washing, bleach resistance, drying time and cost balance. Premium patient linens use T-200 to T-250 or CVC, knitted jersey is used on pressure-relief mattresses, and “hospital grade” means the construction survives institutional laundering, not a legal standard.
International Linens weaves and knits hospital sheeting in its own units, so this guide covers the constructions we actually run and what each one is for. It is written for distributors, laundries and facility buyers comparing specifications.
Types of hospital bed sheets
| Type | Construction | Used for |
|---|---|---|
| Woven flat sheet | Plain weave, T-130 to T-250, 1 to 3 inch hems | Top sheets and flat bottom sheets with hospital corners |
| Woven fitted sheet | Same fabric, all-round elastic, 7 to 15 inch pocket | Standard bottom sheet on most beds |
| Knitted fitted sheet | Single jersey or interlock, 13 to 25 oz | Pressure-relief and variable-depth mattresses, long-term care |
| Draw sheet | Woven or knitted, 54 inch wide | Repositioning patients and protecting the bottom sheet |
| Bariatric sheet | Woven or knitted, 42 to 60 inch widths | Bariatric and expandable frames |
| Stretcher sheet | Woven, 30 inch wide | Gurneys and transport |
| Flannel sheet | Brushed cotton or blend | Occasionally used as a warm top layer or bath blanket; not common as a bottom sheet |
What are hospital sheets made of?
Three fibre options cover almost all hospital bedding. Cotton-polyester, typically 50/50 or 55/45, is the workhorse: it dries fast, resists shrinkage and holds up to bleach, and it is what most US healthcare programs specify. CVC (chief value cotton, around 60/40) gives a softer, more absorbent sheet at a modest premium. 100% cotton is the most comfortable and the most expensive to launder, because it shrinks more, dries slower and wears faster under bleach; it is used in premium rooms and where a facility specifies natural fibre. Knitted sheets are usually cotton-polyester jersey with a small amount of elastane in some constructions.
Thread count explained: T-130 to T-250
T-number is the thread count: warp plus weft threads per square inch. Institutional sheeting is woven at lower counts than retail bedding because durability and drying time matter more than hand feel, and because count above about 200 adds cost without adding wash life.
| Thread count | Feel and use | Typical buyer |
|---|---|---|
| T-130 | Economy, open weave, dries fastest, lowest cost per wash | High-turnover wards, laundries pricing by the pound |
| T-150 to T-170 | Standard hospital sheet; the most common spec in US healthcare | Distributors, hospital groups |
| T-180 | Smoother hand, longer wash life, still economical | Premium patient linens, long-term care |
| T-200 | Percale feel, closer to hotel bedding | Private rooms, rehabilitation |
| T-250 | Sateen or percale, softest institutional sheet | Private hospitals, hospitality-grade healthcare |
What does hospital grade mean?
There is no legal definition of hospital-grade sheets. In practice the term means a sheet built for institutional laundering: a construction that survives repeated washing at 70 to 90 degrees Celsius with chlorine or oxygen bleach, hems and elastic that outlast the fabric, sizing that fits hospital mattresses, and chemical finishing that is safe for broken skin. Buyers should ask a supplier for four things instead of the label: fibre content, thread count or knit weight, the finishing certificate, and wash-test results.
Weave and finish
- Plain weave (percale): crisp, matte, the standard for hospital sheets.
- Sateen: smoother and heavier, used at T-200 and above for premium rooms.
- Crease-resistant finish (CRF): a resin finish that lets sheets come off the ironer flat; specify it if your laundry uses flatwork ironers.
- Whiteness: optical brighteners and bleaching level; ask for the whiteness index if you match linen across suppliers.
- OEKO-TEX Standard 100: certifies the fabric has been tested for harmful substances. Class I, the class for baby articles, is the strictest; our processing is certified to it (certificate 2026OK1630).
Knitted versus woven
Woven sheets are cut to one pocket depth, iron flat and cost less per piece. Knitted sheets stretch to fit mattresses from 6 to 12 inches deep, need no ironing, feel softer on fragile skin and cost more. Knit weight is given in ounces per linear yard: 13 to 17 oz for light, quick-drying sheets and 21 to 25 oz for maximum durability. Most facilities run woven sheets on standard beds and knitted sheets on specialty mattresses. See knitted fitted sheets and woven hospital bed fitted sheets.
What are hospital blankets made of?
Thermal blankets are a leno or cellular weave in cotton or cotton-polyester that traps air while staying light and quick to dry. Bath blankets are a lighter flannel-type weave. Fleece and polyester blankets are used for transport and comfort programs. Flame retardancy and antimicrobial finishes are specified per facility. See hospital blankets.
Choosing the right specification
- Match the fibre to the laundry: cotton-polyester for tunnel washers and bleach, cotton for premium rooms with gentler processing.
- Choose T-150 to T-180 unless a program justifies more.
- Use knitted sheets only where mattress depth varies.
- Specify CRF if you iron.
- Ask for the OEKO-TEX certificate number and wash-test results.
- Set white as the bulk colour and use colours for size or ownership coding.
All of the constructions above are woven, knitted and finished at our units in Faisalabad and supplied in bulk. Start with the hospital bed sheets collection, and use the size chart to set dimensions.
Frequently asked questions
What thread count are hospital sheets?
Usually T-130 to T-180. T-200 and T-250 are used for premium patient rooms.
What are hospital bed sheets made of?
Mostly cotton-polyester blends (50/50 or 55/45), with CVC and 100% cotton for premium programs and knitted jersey for stretch sheets.
What is CVC fabric?
Chief value cotton: a blend with more cotton than polyester, typically 60/40. Softer than 50/50 and still durable.
Are hospital sheets 100% cotton?
Rarely. Cotton shrinks more, dries slower and wears faster under bleach, so blends dominate. 100% cotton is used where a facility specifies it.
What does T-180 mean on a sheet?
A thread count of 180 threads per square inch (warp plus weft). It is a mid-range institutional sheet with a smoother hand than T-130.
Why are hospital sheets white?
White can be bleached hard, shows that it is clean and can be matched across suppliers. Colours are used for coding rather than for the bulk stock.
