How to distinguish between blended fabrics and raw fabrics

Many people cannot distinguish between pure raw materials and blended fabrics when buying clothes or choosing home textiles. Both are cotton clothes, some are soft, breathable, durable and comfortable to wear, while others are prone to pilling, sweating and deformation. The core difference lies in the purity of the raw materials. Without the need for professional equipment, it is easy to distinguish between pure and blended fabrics through four daily methods: sight, touch, burn, and wash.

Intuitive observation method

Pure natural and pure material fabric, with uneven texture and soft matte luster, without any dazzling bright surface. The pure cotton fabric has delicate and casual patterns, while the wool fabric has a fluffy matte texture. The silk has a warm and transparent luster. However, most blended fabrics are mixed with synthetic fibers such as polyester and nylon, resulting in an overall uniform and neat fabric with a cheap and shiny surface. The patterns are rigid and uniform, lacking the natural texture of natural fibers, and the traces of artificial synthesis can be seen at a glance.

Tactile identification method

It is also the most suitable way for daily life. Pure fabric has a warm and skin friendly feel, pure cotton is soft and non greasy, linen is dry, rough and breathable, wool is fluffy and warm, and it fits the skin without feeling cold. The blended fabric has a slightly smooth and hard texture, with exceptionally sufficient elasticity, and almost no wrinkles when pinched and released. Pure materials such as pure cotton and pure hemp will naturally crease and rebound slowly after being pinched, which is a unique characteristic of natural fibers.

Suitable for identifying fabric samples. Pure plant materials such as pure cotton and hemp have a smooth flame and no pungent odor when burned. After burning, they turn into delicate gray white powder that shatters easily with just a pinch. Pure wool and silk belong to animal fibers, with a slight smell of burning hair when burned, slow burning speed, and crispy ash. On the other hand, blended fabrics will emit black smoke and have a pungent plastic smell when burned. After burning, they will form hard black lumps that cannot be crushed. As long as there is clumping, it can be basically determined to be blended fabric.

Finally, the water washing effect can be used to assist in judgment. Slight shrinkage and wrinkling of pure fabric after washing is a normal phenomenon, but the hand feel remains soft. Blended fabrics mixed with synthetic fibers are less prone to shrinkage and wrinkling after washing, but they are prone to pilling, static electricity, and hardening after multiple washes.
