What polyamide is and why it is on the label
Short answer: Polyamide is a synthetic fibre, also known as nylon, that is often blended into socks and tights to give strength and stretch. That is why polyamide often appears on the label next to viscose or cotton. Here is what the fibre does and why it is found in so much clothing.
What polyamide is
Polyamide is a man-made fibre produced from chemical raw materials. It is used in textiles because it is strong and light. The name nylon is often used for the same type of fibre. Polyamide can be spun very thin, which is why it appears in everything from socks to sportswear. That makes it practical in clothing that should be thin yet still withstand being pulled and worn many times.
Why polyamide is in socks
In socks, polyamide contributes strength at the toe and heel, where there is most wear. It also helps the sock keep its shape. Without a strong fibre the toe would soon thin out, and the heel might get holes after a few washes. See all bamboo socks for women and read the label on each style to see what the sock is made of.
Polyamide together with bamboo viscose
Bamboo viscose is soft but not as hard-wearing. That is why it is often blended with polyamide and elastane. The result is a sock that feels soft and still lasts longer. How large a share each fibre makes up is stated on the label and varies from style to style. That is why it is a good idea to compare labels if you want a sock with a larger or smaller synthetic share.
What polyamide does not do
Polyamide does not absorb moisture in the same way as natural fibres or viscose. It is only one part of the whole, and overall comfort depends on the blend, the knit and the fit. You cannot judge everything from one fibre, so read the whole list. Look at everything from viscose to elastane, and think about what matters to you when choosing socks.
How to care for socks with polyamide
Wash by the label and avoid very high heat, which can damage both polyamide and elastane. Use a laundry bag so the socks do not pull on other clothes. Air drying is gentlest. Polyamide usually tolerates regular washing well, but always follow the maker's instructions. Small habits such as a laundry bag and low heat make a difference to how long the socks look good.
If you are sensitive to synthetic fibres
Some people notice a difference between natural and synthetic fibres in clothing that sits close to the skin. If you have sensitive skin, try the socks for a short day and read the label beforehand. If your skin reacts, talk to your doctor about it. Remember that you can always choose a different blend if one does not feel right.
Polyamide in the rest of your clothes
The fibre is also found in tights and underwear. Look at bamboo tights for women and a bamboo slip to see what the blends look like and what place polyamide has. Then you know what you are getting and why it is listed.
