Blending is the combining of different fibres together intimately to achieve a desired product characteristic. Blends can influence colouring, strength, softness, absorbency, ease of washing, resistance to wrinkling, ease of spinning, cost, etc.
Advantages of Blending
- When two different types of fibres are blended, the properties of these two different fibres are synergised. For instance, in the blend of cotton and polyester, cotton provides the absorbency and polyester provides the strength.
- Blending is done to produce a fabric, which is economical by combining the aesthetic comfort properties of the natural fibres with the easy care and strength properties of synthetic fibres.
- Blending also helps to provide the fabric’s light weight with all desirable characteristics.Improving spinning, weaving and finishing efficiency and the uniformity of product.
Methods of blending – Blending can be done at the opening stage, drawing etc.
- In the initial opening stage of the blow room operation, the fibres are spread one on top of the other and fed into the blending feeder.
- The blending can also be done in the carding stage.
- Similarly the blending can be done at drawing or roving stage.
- A filament yarn blended contains yarns of different deniers (denier is the yarn numbering system used for filament yarns, which is explained in unit 13) blended together.
