Scrubs go through more wear and washing than almost any other uniform category — daily industrial laundering, long shifts, and constant movement. Choosing the wrong fabric shows up fast: colors fade within months, seams give way, and staff complain about comfort by the second week. Here's what actually matters when specifying scrub fabric for a hospital or clinic.

1. Blend ratio: cotton vs. polyester

Most hospital-grade scrubs use a poly-cotton blend rather than 100% of either fiber. Pure cotton breathes well but wrinkles fast and shrinks with repeated industrial washing. Pure polyester holds its shape and resists shrinking but can feel hot over a 12-hour shift. A 65/35 polyester-cotton blend is the most common starting point — it holds color and shape through frequent laundering while staying breathable enough for long shifts. For hotter climates or physically demanding units, some hospitals shift toward 55/45 for extra breathability.

2. Fabric weight (GSM)

Fabric weight is measured in grams per square meter (GSM), and it directly affects both comfort and durability:

3. Fluid resistance where it's needed

Not every role needs fluid-repellent treatment, but for surgical, emergency, and lab-facing staff it matters. Fluid-resistant finishes are applied as a coating on the woven fabric and typically reduce breathability slightly — so it's worth specifying this only for the departments that actually need it rather than applying it hospital-wide by default.

4. Color-fastness through industrial laundering

Hospital laundry uses higher wash temperatures and stronger detergents than a home washing machine. If color-coding is part of your department system, ask your supplier specifically about color-fastness ratings under industrial laundering conditions — a scrub set that looks identical to another department after 40 washes defeats the purpose of the color system.

The practical takeaway

For most general hospital departments, a 65/35 poly-cotton blend at 160–180 GSM covers comfort and durability well. Reserve heavier, fluid-resistant fabric for surgical and emergency units specifically, rather than standardizing the most expensive option across every department. A good supplier will walk through these trade-offs with you per department, not just sell one fabric for the entire order.
