1. Different sources
Although both cashmere and wool come from sheep,
They actually come from different species of sheep.
Wool comes from sheep, while cashmere comes from goats.
Wool: From sheep. Even the finer ones are called wool.
Characteristics of wool products: full, warm and comfortable feel.
Cashmere is a thin layer of fine wool that grows on the outer skin of a goat, hidden at the roots of the goat's coarse hair.
After being stimulated by the cold wave in early winter, it grows to resist the wind and cold, and naturally falls off when the weather gets warmer the next spring. It is a rare animal fiber.
2. Different warmth retention and hygroscopicity
The feel and warmth of cashmere are much better than that of wool (cashmere is 8 times warmer than wool), it is lighter than wool, and its weight is only one-fifth of wool, but it is also more delicate and less durable than wool.
Cashmere has the strongest water absorption among all textile fibers, with a moisture regain rate of more than 15%.
If you immerse a cashmere sweater in water, it will be completely soaked in just a few seconds, while most wool sweaters will take more than half a minute to be completely soaked.
Therefore, cashmere is significantly better than wool in terms of hygroscopicity.
Therefore, cashmere will not fade after dyeing.
And the color is full. It's also more breathable and comfortable to wear.
