Shiny fabric and why clothes get a sheen

Short answer: Shiny fabric gets its sheen from how light is reflected from the surface, and that is governed by the fibre, the yarn and how the fabric is made. Smooth fibres and a tight knit more often give an even surface that shimmers lightly. Here we explain why a garment can look shiny and what affects it.

How sheen arises in a fabric

Light that hits a smooth surface is reflected evenly and gives a slight sheen, while an uneven surface scatters the light and looks duller. That is why two garments in the same colour can look different. Sheen is about the structure of the surface and not about the garment being of a particular quality.

The fibre plays a part

Some fibres are smooth and long and therefore reflect light better. Viscose is one example, because the fibre is made as an even thread. Natural fibres such as cotton have a more uneven surface and often look duller. The difference is usually mild in jersey, but it can be seen in some light.

Knit and weave decide a lot

How the yarn is knitted or woven affects the surface. A tight, even fabric gives more smooth areas that reflect light, while a coarser fabric looks duller. Look at the range for men to see how different fabrics can look in real life.

Colour and finishing

Dark colours show sheen more clearly than light ones. Finishing of the fabric can also make the surface smoother, and that can change how the light is reflected. Some fabrics therefore have a clear sheen straight away, while others look duller. Read the description if you want to know how the surface is meant to look.

Sheen that appears over time

Sheen can also appear when a garment has been worn or pressed. Ironing and hard rubbing can flatten the surface so it becomes shiny in places. It is often seen where the garment is exposed to pressure. So iron gently and follow the care label on the garment.

Washing that affects the surface

Washing can change the surface of the fabric, for better or worse. Gentle washing and a sensible amount of detergent help the surface stay even. High heat and hard spinning can cause pills and uneven sheen. So wash the garment inside out and follow the care label.

Choose the surface by use

Think about how the garment will be used. A garment with a matt surface often suits everyday life, while a little sheen can give a smarter impression. Look at bamboo clothing for men and compare the surface of different garments. Light in a shop and at home can look different, so try at home.

Long sleeves and more garments

The surface is often most visible on larger areas, such as a long sleeve or a top. Look at long sleeve models and see how the light falls on the fabric. Compare several garments in daylight, and you will get an idea of how shiny the fabric really is.

Frequently asked questions

Why does fabric become shiny

Light is reflected evenly from a smooth surface and gives sheen. Fibre, yarn, knit and finishing decide how smooth the surface becomes, and wear can also create shiny areas.

Is shiny fabric a sign of quality

No, sheen says nothing about quality. It shows how the surface reflects light, and it can come from the fibre, the making or how the garment is worn and washed.

How do I avoid shiny patches on clothes

Iron gently, avoid hard rubbing and wash the garment inside out on a gentle cycle. Always follow the care label on the garment.
