Textile Engineering

1.  What is Mixing in Spinning?
 In spinning sector, if various grades of same fibres are kept
together for producing yarnthen it is termed as mixing.
Suppose, a yarn is produced by using 60% Indian cotton and
40% Egyptian cotton then it is called mixing.

 Mixing and blending of textile fibres in
spinning
 Types of Mixing Applied in Spinning:
 There are different types of mixing as done in spinning
sector for producing yarn. Those are in the below:
 Automatic mixing,
 Mixing by hopper,
 Bin mixing,
 Volume mixing,
 Hand stock mixing,
 Lap mixing,
 Sliver mixing,

2.  Weight mixing,
 Card mixing.
What is Blending in Spinning?
 In spinning sector, when various fibres of different or same
grades are kept together then it is termed as blending.
Suppose, a yarn produced by using 60% cotton yarn and 40%
polyester yarn then it’s called as blending.
 Objects of Blending in Spinning:
 The key objects of blending have pointed out in the
following:
 Blending is used to provide the requiredfeatures to the end
product.
 It is used to control and decrease of yarn production cost.
 It is used to achieve uniform quality of yarn.
 It helps to meet functions and end used requirement.
 It is aesthetic such as texture, fashion, drape luster etc.
 Blending is used to develop yarn processing performance.
 It is also used to achieve different effects by carrying color,
characteristics of fiber and so on.
