Blending

Blending


Usually blending refers to the mixing and combining two or more than two fibres of different origins. For example cotton fibres with polyester. The purpose of blending is to achieve desired properties of both the components of the fibres in a yarn which otherwise is unobtainable from a single component For example strength, crease resistance. colour, price, moisture absorption drying properties, ete.

Just as mixing, blending should also be done thoroughly so that a homogenous yarn may be produced out of the component fibres

OBJECTS OF BLENDING


1. Blending influences the reduction of the cost of the final product through blend composilion. availability of fibres quality& inherent fibre property variations

 2. It helps to improve processing performance of the following process –
 (i) Carding: Blending influences the processing performance of carding through control of nep level variation, waste level variation, fly, roving twist variation, m/c adjustment, static electricity formation


(ii) Spinning: Blending influences the processing performance of spinning through control of yarn twist variation, end breakage, m/c adjustment etc.


iii) Warping & weaving: Blending influences the processing performance of warping & weaving  through control of end break m/c adjustment etc.

(iv) Dyeing & finishing: Blending influences the behavior of dyeing& finishing through control of shrinkage variation, dyeing defects etc

3. Blending influences

 (i) Aesthetic properties: It influences to increase luster, Appearance, cover, color etc.

 (ii) Subjective properties: It increases comfort & the properties like handlings, touch, softness etc

4. It helps to meet function & end used requirements 

5. It helps to achieve effect by carrying color, fibre characteristics & so on
