Comparision between mixing and blending in Blowroom

Blending means, in very unit cross section of the yarn, every fibre characteristic is found in the same proportion of different cotton as in the original blend.

Blending is based on the measurement of important fibre properties 1ike 1ength, fineness, strength, etc. and quantitatively proportioning and combining the compatible Properties under controlled condition.

Physical properties (fibre length, fineness, strength) of the resultant blend can be predicted, and are reproducible.

It is combining together in some what haphazard proportions of different cottons whose physical properties are only partially known, and the resultant mixture has average physical property characteristic which are not easily reproducible. Totally, blending is based on principles of measurement and proportion while mixing is not.
