Scrubs Fabrics Compared: Polyester, Cotton, Viscose and Stretch Blends

Most scrubs are made from blends rather than a single fibre. Poly-cotton is the practical all-rounder for frequent hot washing, polyester-rich blends hold their colour and shape and dry quickly, viscose (rayon) adds softness and drape, and a small amount of elastane adds stretch for long, active shifts. The right choice depends on the role, how the scrubs are laundered and how many hours staff spend in them.

This guide explains what each fibre contributes, how the common blends compare, and how to match fabric to roles across a clinic or hospital.

What each fibre brings

Polyester

Polyester is a synthetic fibre and the backbone of most modern scrub fabrics.

• Strengths: durable, holds its shape, resists creasing and shrinking, dries quickly and generally holds dye well.
• Weaknesses: on its own it breathes less and can feel less soft than natural fibres; lower-grade polyester can pill.
• In scrubs: rarely used alone for clinical scrubs; usually blended with cotton or viscose.

Cotton

Cotton is a natural fibre valued for comfort against the skin.

• Strengths: breathable, absorbent and soft; tolerates high washing temperatures.
• Weaknesses: creases easily, can shrink if the fabric has not been pre-treated, dries slowly, and colours can fade faster with repeated hot washing.
• In scrubs: 100% cotton scrubs exist, but institutional scrubs usually blend cotton with polyester for durability and easier care.

Viscose (rayon)

Viscose is a regenerated cellulose fibre, made from wood pulp; rayon is the broader name for the same family.

• Strengths: very soft and smooth, drapes well and gives a more refined look; comfortable next to the skin.
• Weaknesses: weaker when wet, and less tolerant of very hot washing and harsh tumble drying than polyester or cotton.
• In scrubs: blended with polyester, often with elastane, for soft, modern-looking scrubs.

Elastane (spandex)

Elastane, also sold under brand names such as Lycra, is a highly elastic synthetic fibre used in small proportions.

• Strengths: adds stretch and recovery, so garments move with the body and keep their shape.
• Weaknesses: sensitive to heat; very hot washing and drying can reduce the stretch over time.
• In scrubs: a small percentage in a blend is enough to make scrubs noticeably more comfortable for active roles.

Common scrubs blends compared

Blend	Feel	Tolerance of hot washing	Crease resistance	Stretch	Typical use
Poly-cotton	Firm, crisp	High	Good	None	General clinical roles, commercial laundry, high-turnover programmes
100% cotton	Soft, natural	Moderate; can shrink and fade	Low	None	Staff who prioritise a natural fibre, lighter-duty roles
100% polyester	Smooth, can feel synthetic	High	Very good	Little or none	Some budget scrubs and outer layers
Polyester-viscose	Soft, smooth	Moderate	Good	None	Consultation and front-of-house roles
Polyester-viscose-elastane	Soft, stretchy	Moderate; follow the care label	Good	Yes	Long shifts, active and hands-on roles
Polyester-cotton-elastane	Firmer, with some stretch	Fairly high	Good	Yes	Teams that want stretch with tougher laundering

These are general characteristics. Real performance depends on the specific fabric, including its weave, weight and finishing, so always judge a sample rather than a label.

Matching fabric to roles

Different roles in the same organisation can justify different fabrics, as long as colours and branding stay consistent so the team still looks like one team.

High-wash, high-turnover roles

Ward nurses, emergency staff and support teams whose scrubs go through a commercial or hospital laundry are well served by poly-cotton, or a tougher stretch blend that tolerates hot washing and tumble drying.

Long, active shifts

Staff who bend, lift, reach and walk all day, such as nurses on long shifts, physiotherapists and dental assistants, often prefer a polyester-viscose-elastane stretch fabric. Our comparison of stretch scrubs vs traditional scrubs covers the trade-offs in comfort, durability and cost.

Consultation and front-of-house

Outpatient doctors, aesthetic practitioners and reception staff in scrubs tend to value appearance: a smooth, soft fabric that drapes well and still looks neat at the end of the day.

Laboratory and diagnostic roles

Lab and diagnostic staff often wear scrubs under a coat, so the scrub fabric mainly needs to be comfortable and easy to wash, while the outer layer takes most of the wear. A durable poly-cotton under a lab coat is a common combination, and choosing the two together keeps colours and branding consistent.

Staff who launder at home

If staff wash their own scrubs, choose a fabric that copes with ordinary domestic washing and drying without special handling, and give everyone the same clear care instructions. Pale colours in cotton-rich fabrics are the most likely to look tired quickly with home washing, so a polyester-rich blend is often the safer choice.

Mixed teams on one programme

Most clinics end up with two fabrics at most: one hard-wearing main fabric for the majority and a stretch option for roles that move the most. Keep the colours, cut and branding identical so that a patient sees one team, whatever fabric each person has chosen. Record which staff have which fabric, so reorders arrive in the right one.

Weight, weave and finish

Composition is only part of the picture.

• Weight: heavier fabrics feel more substantial and are less see-through in pale colours; lighter fabrics feel cooler. In the UAE, where staff often move between outdoor heat and cold air-conditioned wards, the balance matters; see the best scrubs fabric for hot weather.
• Weave: twill weaves are hard-wearing and hide creases; plain weaves are smooth and light; some stretch fabrics use constructions designed for extra give.
• Finish: brushing gives a softer handle, and some fabrics carry antimicrobial or fluid-repellent finishes. If a finish matters to you, ask the supplier for test documentation, and remember that scrubs are uniform garments, not certified PPE.

Fabric and colour go together

Fibres take dye differently. Polyester-rich blends generally keep their colour well through washing, while cotton-rich fabrics can fade faster with frequent hot washing. If you choose deep colours such as navy, wine or black, ask how the fabric looks after repeated washes, and compare a washed piece against a new one. The causes of fading, and how to specify against it, are covered in why scrubs fade.

How to evaluate fabric samples

1. Get the composition and weight of every fabric offered, in writing.
2. Handle swatches in your actual colour; the same base fabric can feel slightly different in different shades.
3. Wash a sample garment several times using your normal laundry method and compare it with an unwashed piece.
4. Wear-test a set for a full shift, ideally with staff from different roles.
5. Check for pilling at friction points such as the inner thighs, underarms and where bags rub.
6. Check opacity of light colours in daylight.
7. Confirm the care instructions match how the scrubs will really be washed and dried.

Quick decision guide

• Commercial laundry and hot washes: poly-cotton
• Long shifts and active work: polyester-viscose-elastane stretch
• A polished, soft look for consultation roles: polyester-viscose, with or without stretch
• Natural feel above all: cotton-rich, accepting more creasing and some fading
• A mixed team: one main fabric plus a stretch option, in the same colours

Choosing fabric for your team

MISHAREN makes scrubs to order at its own unit in Kerala, India, in poly-cotton for frequent hot washing and in polyester-viscose-elastane stretch for long shifts, and you can test a sample before ordering in bulk.
