The methods for identifying the composition of clothing fabrics mainly include checking labels, looking with eyes and touching with hands, and burning methods. ‌

Checking labels: Legitimate clothing brands usually clearly label the composition of the fabric on the label, such as cotton, polyester, spandex, etc., which is the most direct way. ‌

Seeing with eyes and touching with hands: Different fabrics have their own characteristics in appearance and feel. For example, all cotton fabric has a soft touch and good breathability, while T/C fabric is smoother and firmer. In addition, various fibers are distinguished by their sensory characteristics, such as cotton's slender and soft texture, low elasticity, and easy wrinkling; The texture of hemp is rough and hard, often with defects; Silk has a glossy texture, soft and lightweight; Wool is elastic, has a soft luster, a warm touch, and is not easily wrinkled. ‌

Combustion method: This is a relatively professional identification method. By burning a small piece of fabric and observing its characteristics such as flame, smoke color, and ash, the composition of the fabric can be preliminarily determined. For example, when cotton fibers burn, the flame is yellow, there is a smell of burning paper, and the ash is gray white; And T/C burns out a bit hard balls; The black balls produced by burning polyester are hard and have a lot of black smoke. ‌

In addition to the above methods, there are other identification methods such as microscopic observation, reagent coloring, dyeing, and dissolution, which require professional equipment and knowledge and are suitable for professional laboratories or occasions with special research needs for fabrics. In practical applications, viewing tags and using sensory methods are the most commonly used and easy to operate methods. ‌
