How to distinguish pure wool and chemical fiber

Jun 16/2022 / news / Author: DongJing

The identification of wool is mainly through feel, burning and other methods.
The feel of wool is soft and not tangled, and non-wool is relatively stiff. Burning is a more accurate identification method. After burning, the wool turns into a black powder when it is pinched; and the chemical fiber becomes a light brown lump after burning, which is not easy to be crushed.
The difference between pure wool and chemical fiber
First, the luster is different. Most pure wool fabrics are soft and natural with beautiful colors; while chemical fiber imitation wool fabrics have rich and bright colors. If you look closely in the sun, you will often see dazzling light spots.
Second, the feel and elasticity are different. Pure wool fabrics are soft to the touch, smooth and boney. When you squeeze the fabric tightly with your hands or shake it with your hands, it has a sense of flexibility, with a slight wrinkle but not hard, soft rebound but not rigid; It looks like wool in appearance, but feels soft and smooth, with no bones, many wrinkles and slow rebound.
Third, burn it after spinning. After the pure wool fabric is drawn and twisted, it can be seen that the wool fibers have uneven thickness, different lengths, and natural curls; while the viscose wool-like fabrics have uniform lengths and thicknesses. After the pure wool is burned, it will burn slowly, and it will continue to burn after leaving the flame, accompanied by the smell of burning hair. The imitation wool ignites when it is close to the flame, burning rapidly, the flame is yellow, accompanied by the smell of burning paper, and the ash contains white light ash that is easily scattered, and leaves hard lumps that are easily crushed.
Dozens of different shapes of granular wool, according to the length of the fleece, the curvature and the gloss, have a variety of grain textures, various curls, and similar coral fleece, imitation rabbit fur and gold and silver wire products, etc. !
Granulated fleece is a kind of knitted fabric. It is a small ingot knitted structure, which is woven on a large circular machine. After weaving, the grey fabric is first dyed, and then processed by various complex finishing processes such as brushing, carding, shearing, and shaking. , The front of the fabric is brushed, the fleece is fluffy and dense, and it is not easy to shed and pilling, the reverse is sparse and well-proportioned, the fluff is short, the texture is clear, and the fluffy elasticity is particularly good. Its ingredients are generally all-polyester and soft to the touch. In addition, the granular fleece can also be compounded to make the effect of keeping out the cold better.
Small ingot knitted structure
Compared with the commonly known polar fleece on the market, the granular fleece displayed this time has a richer and finer fleece feel. And most of the garments in the show are compounded with suede or down fabrics with similar colors. Isn't the biggest disadvantage of knitted flannel because it is too soft and the upper body is invisible? The composite fabric is smooth but crisp, with better warmth retention, close to the real fur
