What are the physical and chemical properties of Fibre?
Physical & Chemical Properties of Wool Fibre
| SL. No. | Parameters | Properties |
|---|---|---|
| 6 | Hygroscopic (Moisture capacity 14 – 18%) | Higher than other fibres. |
| 7 | Hand Feel | Soft |
| 8 | Specific Gravity | 1.32 and so fabrics fees lighter than cellulose. |
| 9 | Dissolvability | Wool dissolved in alkali solution |
What are the chemical properties of Fibre?
The natural fiber can be considered as a composite material consisting of cellulose, hemicelluoses, pectin, lignin, and waxes. The reinforcing elements of natural fibers are cellulose microfibrils; the microfibrils are surrounded by the matrix elements — hemicelluloses and lignin.
What are the physical types of fibers?
It may be natural like silk or synthetic like Nylon. Filament fibers are measured in yards or meters. Silk, in filament form, is reeled from cocoons. Man-made fibers of a chemical composition, liquid nature are forced through spinnerets, hardened and produced into continuous filament strands of a determined length.
What are the physical properties of fabric?
Physical properties of Fabrics
- Fiber or filament: type, size, length.
- Yarn: diameter, twist, weight or size, count, fiber content for mixed yarns, ply.
- Weight: ounces per squared or yards per pound.
- Thickness: vertical depth.
- Fabric structure.
- Woven fabrics: weave type, warp and filling yarn count per linear inch
What are the physical properties of wool Fibre?
Color: The color of wool fiber could be white, near white, brown and black. Tensile Strength: The tensile strength of wool in dry condition is 1 – 1.7 and 0.8 – 1.6 in wet condition. Elongation at break: Standard elongation is 25 – 35% and 25 – 50% in wet condition. Elastic Recovery: Good.
What are the physical and chemical properties of polyester?

What is fiber material?
Fiber or fibre (from Latin: fibra) is a natural or man-made substance that is significantly longer than it is wide. Fibers are often used in the manufacture of other materials. The strongest engineering materials often incorporate fibers, for example carbon fiber and ultra-high-molecular-weight polyethylene.
What are four properties of textiles?
When looking at basic properties of fabric, there are certain features which are necessary to consider; breathability, weight, drape, durability, softness, construction and whether it is a water-repellent fabric.
What is a chemical property of wool?
Chemical Properties of the wool fiber is given below: Effects of Acids: Wool is attacked by hot concentrated sulphuric acid and decomposes completely. It is in general resistant to mineral acids of all strength even at high temperature though nitric acids tend to cause damage by oxidation.
What are the chemical properties of wool?
Wool fibre is a protein known as keratin. Keratin is made up of amino-acids joined by peptide linkages. In addition to carbon, hydrogen, oxygen and nitrogen it also contains sulphur. The amino-acids present in wool are mainly bulky, while silk has chiefly small amino-acids.
