define the following fibre characteristics
-conduction of heat
-texture
-lustre
-moisture absorbency
-strenght
-flammability
Sure! Here are the definitions of the fiber characteristics you mentioned:
1. Conduction of heat: It refers to the ability of a fiber to transfer heat. Some fibers, like wool, have good heat conduction properties, meaning they can absorb and release heat quickly. Others, like cotton, have poor heat conduction properties and tend to hold onto heat.
2. Texture: This refers to the feel or surface characteristics of a fiber. It includes properties like softness, smoothness, roughness, or coarseness. For example, silk is known for its smooth and luxurious texture, while hemp has a rougher texture.
3. Lustre: Lustre describes the brightness or shininess of a fiber. It varies from fiber to fiber. For instance, silk and satin have a high lustre, giving them a glossy appearance, while cotton has a lower lustre and appears more matte.
4. Moisture absorbency: This refers to how well a fiber can absorb moisture. Some fibers, like cotton and linen, have good moisture absorbency, making them comfortable to wear in hot weather as they can wick away sweat. In contrast, synthetic fibers like polyester have lower moisture absorbency.
5. Strength: Strength refers to the tensile strength or resistance to breaking of a fiber. It measures how well the fiber can withstand pulling or stretching. Natural fibers like silk and wool are known for their strength, while synthetic fibers like nylon and polyester also exhibit high strength.
6. Flammability: Flammability is the ability of a fiber to ignite and sustain combustion. Some fibers, like cotton and wool, have relatively low flammability. On the other hand, synthetic fibers like polyester and nylon tend to be more flammable and can melt when exposed to flames.
By understanding these fiber characteristics, you can make informed choices about the suitability of different fibers for various applications such as clothing, upholstery, or other textile products.
