An easy way to identify the composition of a fabric is the combustion method. Another complicating method is the sensory method. The following is an introduction of the two methods.

Clothing fabric identification method--combustion method

An easy way to identify the composition of a fabric is the combustion method. The method is to draw a cloth containing warp and weft yarn at the seam edge of the garment, then igniting it with fire and observing the state of the burning flame, smelling the smell after burning the cloth, and seeing the remaining matter after burning, thereby judging whether it matches the fabric component marked on the durability label of the garment to distinguish the authenticity of the fabric component. Both the cotton yarn and the hemp yarn are burning near the flame. Burning rapidly, the flame is yellow, and blue smoke is emitted. The difference between the odor of burning and the ash after burning is that the burning of cotton gives off a smell of paper, and the burning of sesame produces a scent of ash after burning. The cotton has very little powder ash, which is black or gray, and the hemp produces a small amount of grayish white powder ash.

When the wool yarn and the silk hair meet the fire, they will smoke, and when they burn, they will foam and be slower, and at the same time, they will emit the burnt smell of the hair. After burning, the ash is mostly shiny black spherical particles, and the fingers are crushed. The silk huddled in a fire, and the burning speed was slower, accompanied by a squeaking sound, which gave off the burning smell of the hair. After burning, it will form a dark brown globular ash, which will be broken by hand.

When the nylon is close to the flame, it will quickly curl and melt into a white gel, which will melt and blister in the flame. It burns without a flame, and it is difficult to continue to burn away from the flame, giving off a celery flavor. After cooling, the light brown melt is not easily broken. Polyester is easy to ignite and it melts near the flame. When it burns, it emits black smoke when it melts. It has a yellow flame and emits a fragrant smell. After burning, the ash is a dark brown block and can be broken with fingers. 

Clothing fabric identification method--sensory method

The surface of the cotton cloth is soft, soft for the touch but less elastic, and it is also easy to wrinkle. After the cloth is squeezed by hand, it is loosened, and the wrinkles are noticeable, and the crease is not easily restored. If we take a few yarns from the edge of the cloth and look at it, the length of the yarn is not the same.

The surface of the sticky cotton cloth is soft and bright, bright and colorful, smooth and soft, and has poor elasticity. After the cloth is squeezed by hand, it is loosened, and the crease is visible, and the crease is not easily restored.

The gloss of polyester and cotton cloth is brighter than pure cotton cloth, the cloth surface is flat, clean and free of yarn ends or impurities. It feels smooth and crisp, and its elasticity is better than that of pure cotton. After the hand is squeezed, the fabric is loosened, the crease is not obvious, and it is easy to return to its original state.

The surface of the pure wool worsted fabric is smooth, and the texture is fine and clear. The gloss is soft and natural, and the color is pure. The surface is pinched by hand, the crease is not obvious, and it can be quickly restored to its original state. Most of the yarn counts are double strands.

The pure woolen hair is full and the texture is tight and thick. The surface has fine fluff, and the texture is generally not revealed. The yarn is mostly a single yarn. The blended woolen velvet has smooth surface, a strong hair feel, a waxy appearance and a stiff hand. After the hand is squeezed, the material is loosened, and there is a clear crease, which can slowly return to its original state.

We have to choose different methods of identification depending on the type of fabric. I hope the above can help you.
