Burning Test for Textile Fiber

This is a mind map introducing the burning test for textile fiber. Through the burning test, people can identify whether it is natural fiber or man-made fiber. Natural fibers include cotton, linen, silk, and wool, while man-made fibers include acetate, acrylic, nylon, polyester, and rayon. However, the burning test also has limitations. It is apparent that many fibers have similar burning reactions that might cause doubt and occasional confusion. More details are shown on the mind map. You can discover more templates on EdrawMind and create a mind map for your learning easily.

Fabric Identification

to know the identification of fabric.To identify fabric that is unknown, a simple burn test can be done to determine if the fabric is a natural fiber, man made fiber, or a blend of natural and man made fibers. The burn test is used by many fabric stores and designers and takes practice to determine the exact fiber content. However, an inexperienced person can still determine the difference between many fibers to "narrow" the choices down to natural or man made fibers. This elimination process will give information necessary to decide the care of the fabric.

Identification of Natural Fibers Through Burning Test

Cotton

a steady flame

smells like burning leaves

The ash left is easily crumbled

easily extinguished

Linen

takes longer to ignite

the ash is very brittle

easily extinguished

Slik

protein fiber

burns readily, not necessarily with a steady flame

smells like burning hair

The ash is easily crumbled

are not as easily extinguished as cotton or linen

Wool

protein fiber but is harder to ignite than silk

The flame is steady but more difficult to keep burning

The smell of burning wool is like burning hair

Identification of Man Made Fibers Through Burning Test

Acetate

burns readily with a flickering flame

cannot be easily extinguished

The burning cellulose drips and leaves a hard ash

The smell is similar to burning wood chips

Acrylic

burn readily due to the fibre content and the lofty, air filled pockets

A match dropped on an acrylic blanket can ignite the fabric which will burn rapidly unless extinguished

The ash is hard

The smell is acrid or harsh

Nylon

Nylon melts and then burns rapidly if the flame remains on the melted fibre

If you can keep the flame on the melting nylon, it smells like burning plastic

Polyester

Polyester melts and burns at the same time

the melting, burning ash can bond quickly to any surface it drips on including skin.

The smoke from polyester is black with a sweetish smell

The extinguished ash is hard

Rayon

It is a regenerated cellulose fibre which is almost pure cellulose

Rayon burns rapidly and leaves only a slight ash

The burning smell is close to burning leaves

Limitations

It is apparent that many fibers have similar burning reactions that might cause doubt and occasional confusion
