Fibre is the foundation of all textile products. To achieve the target fabric specifications, we must begin with the appropriate fibre properties. Different fibre properties have a significant influence on yarn as well as fabric quality. Let’s have a look as below-
Fibre Quality
Definition
Yarn Impacts
Fabric Impacts
Micronaire value
The fineness and maturity of the fibre
Evenness/imperfections, spinning efficiency, strength etc.
Dye-ability, white specs, appearance, strength, etc.
Staple length
The length of the fibre reported as the average length of the longer one-half of the fibre (upper half mean length).
Evenness/imperfections, spinning efficiency, strength, hairiness, etc.
Appearance, strength, pilling, etc.
Length uniformity
The length variation of the fibres and the best indicator of short fibre content.
Evenness/imperfections, spinning efficiency, strength, hairiness, etc.
Appearance, strength, pilling, etc.
Strength
The amount of force required to break a bundle of fibre.
Spinning efficiency, strength, etc.
Strength
Colour grade
The fibre reflectance and yellowness of the fibre.
–
Dye-ability and appearance.
Trash grade
The amount of leaf, plant, and other non-lint material in the cotton fibre.
