How Can You Tell That It Is Real Wool?

The importance of verifying whether a piece of wool clothing item has wool content or not can never be overstated.

This can help you avoid laundry accidents, especially if you purchase a piece of fabric with no fiber content label or come in possession of an unmarked material or piece of vintage clothing.

How To Know If Your Wool Clothing Item Is Made From Real Wool?

It is also essential to know the wool content of fabrics if you want to grab supposed bargains at markets while on vacation.

Unfortunately, valuable fabrics such as cashmere, alpaca or merino wool are often counterfeited or have a percentage of synthetic fibers added.

If you sell or give away fabrics, they should be adequately labeled because potential buyers may be allergic to wool or lanolin.

Information about wool content is also essential if you want to dye fabrics, as most dyes are specific to certain fibers.

Here are  tests that you can use to determine the fiber of your fabric with the help of common household items:

The Burn Test - Identify Real Wool

The burning test is a rapid method for identifying fibrous materials and other materials, also plastics. It is used to distinguish between the major types of raw materials and between the various synthetic fibers.

It is not very suitable for textile of different fibrous materials. For this purpose, the different fibers would have to be separated from the composite and tested individually.

We explicit point out that this test should not be performed at home! Be warned that something could catch fire –

if you are not working carefully enough!

There are certain safety precautions that must be put in place before carrying out a burn test. First, you need to make sure you’re working in an area that is well ventilated.

The burning fabric should only be held with tongs or metal tweezers and there should be a fire extinguisher around, just in case.
Also, avoid using refillable lighters or matches with strong fuel smell, it is better to use a disposable lighter – the smell of the fiber is essential for identification.

The fact that you need to be able to identify the smell of the fiber explains why you should not do this test when you have a cold or sinus problem.

Performing the Burn Test

Step 1
You need to carefully remove several fibers from the mystery fabric from a place where it won’t be noticed. Wind the fibers tightly around one end of a metal wire that can’t burn.

Step 2
Fill your glass bowl with some water.

Step 3
Light your match

Step 4
Hold fabric over bowl and touch with the lit match. An original wool fabric will immediately catch fire and maintain a steady burn, though it might be difficult to keep it burning. Burnt wool fabrics have the smell of burning hair.
