Properties of Wool
Wool, is a natural fiber possessing several
properties, that make it useful in textiles, apparels and home
furnishings. Some of the important properties are:
- Strength: Wool is the weakest of
the natural fibers. Various wool fabrics are made more durable, by
using selected grades of recycled wool. The fiber is strengthened by
the use of ply yarns.
- Elasticity: The fiber is very
elastic and can be stretched to 25 to 30 percent of the natural
length. Wool and wool blend fabrics are given mechanical crimps and
also chemical treatments to increase the elasticity. Chemical
treatments lead to improved shape retention.
- Resilience: Wool fiber has high
resilience, therefore it does not wrinkle much. The wrinkles, if
any, smooth when the fabric is steamed.
- Absorbency: Wool tends to be a
water repellent, but if the moisture seeps in, it can absorb about
20 percent of its weight.
- Heat Conductivity: The natural
fiber is a non conductor of heat, therefore wool is excellent for
manufacturing winter wear garments, carpets and rugs.
