Purchasing work clothes T-shirts, how to quickly identify whether it is pure cotton?

The sister who does the purchasing must understand this kind of pain? The company needs to order a batch of work clothes T-shirts. All the suppliers say they are pure cotton. As a result, the employees will pilling, sweating, and smelling after wearing it for two days. How can I quickly identify pure cotton? Make it clear once today?

The first trick: look at the label + burn the thread

The washing water label of a regular pure cotton T-shirt will clearly mark "100% cotton" or "pure cotton". If it says "cotton blend", "CVC" and "polyester-cotton", the pure cotton content may only be 30% -60%.

The more direct way is to find a sample dress, pull a thread from the seam and burn it with a lighter.

When pure cotton burns: the flame is orange-yellow, the smell is like burning paper, and the ashes are gray-white fine powder, which will be broken when twisted.

When chemical fiber burns: the flame has black smoke, the smell is pungent like plastic, and the ashes are black lumps, which cannot be crushed.

This method can be done on site, and the supplier cannot stop it.

The second trick: feel + stretch test

Pure cotton is soft to the touch but has a slight astringency. If you pinch it and release it, there will be natural folds. The polyester fabric is slippery and leaves almost no marks after letting go.

Do another stretch test: grab the T-shirt with both hands and pull it sideways.

Pure cotton: small elasticity, slow rebound, fine cotton fiber fluff can be seen after stretching.

Chemical fiber: elastic, let go of the instant return to its original state, the surface is smooth.

If the supplier says "pure cotton but with stretch fiber," then at least 5% -10% elastane, comfort will be discounted.

The third trick: look at the price + look at the manufacturer

To be honest, the ex-factory price of a true 100% cotton work clothes T-shirt will not be less than 25-35 yuan (regular gram weight 180-200g). If the quotation is 15 yuan and the logo is also printed, it is most likely a polyester-cotton blend or recycled cotton.

So choosing a supplier is more important than choosing a fabric. Like Shenzhen Yasenman Garment Co., Ltd., which has been specializing in the customization of corporate work clothes for more than ten years, each batch of fabrics provides a composition test report to support on-site combustion testing. Pure cotton is pure cotton, and no word games are played. Their pure cotton T-shirts use Xinjiang long-staple cotton, which is heavy enough, does not fade, and does not pilling. Employees wear them all summer without sweating.
