Characteristics and uses of wool What kind of wool is introduced?

1, plasticity: under the action of steam, wool fibers gradually expand, soften and lose elasticity. At this time, if the wool is pressed into various shapes and cooled quickly, its pressed shape can be maintained for a long time, although the pressure is released. Because of its strong plasticity, it can enhance the aesthetic feeling of the fabric.

2. Shrinkage: Under the action of mechanical external force, wool fibers are treated with a certain temperature (40-50℃) and a felting agent, so that the wool fibers are closely meshed with each other, causing surface shrinkage, increasing the thickness of the fabric, and the wool fabric is felted.

3. Hygroscopicity: Wool is a kind of fiber with strong hygroscopicity. In general, the moisture regain of wool is about 4%, reaching 30% in humid air, and the saturation point can reach 50%.

4. Elasticity: Wool fibers usually bend naturally. If stretched and straightened by external force, the fiber will quickly return to its original bending state after the external force is removed. This property is called elasticity of wool. The magnitude of elasticity is expressed by the rebound rate. Wool has a high resilience, and its fabric is not easy to wrinkle during use, and it can remain stiff for a long time.

5. Mothproof property: protein is the main component of wool, and protein is the first-class food of many moths, so the moth-proofing property of wool products is very poor, and it is very easy to be eaten by insects.

6. Wool is the main textile material in Asia and Europe. Wool fiber is soft and elastic, and can be used to make woolen cloth, wool, blankets, felts and other textiles.
