Question:
Match List - I with List - II.
List - I (Fibre property) List - II (Method used) A. Fibre length
B. Fibre fineness
C. Fibre maturity
D. Fibre strength I. Stelometer
II. Differential dyeing method
III. Gravimetric method
IV. Digital fibro graph
Match List - I with List - II.
| List - I (Fibre property) | List - II (Method used) |
|---|---|
| A. Fibre length B. Fibre fineness C. Fibre maturity D. Fibre strength | I. Stelometer II. Differential dyeing method III. Gravimetric method IV. Digital fibro graph |
Show Hint
Instrument identification: Stelometer = Strength, Fibrograph = Length, Gravimetric = Weight/Fineness. Dyeing is the unique chemical way to see maturity.

The Correct Option is B
Solution and Explanation
Concept:
Fibre characterization involves measuring physical dimensions and mechanical strength. Standardized instruments provide objective data necessary for spinning quality control.
Step 1: Evaluating Length and Fineness Measurement.
Fibre length in cotton is most commonly measured using a Digital fibro graph, which provides span length data. Fibre fineness (linear density) is determined by the Gravimetric method, which involves weighing a known length of fibers.
Step 2: Evaluating Maturity and Strength Measurement.
Fibre maturity (the degree of cell wall development) can be assessed via the Differential dyeing method, where mature and immature fibers take up dyes differently. Fibre strength is measured using a Stelometer, which tests the breaking tenacity of a fiber bundle.
Step 3: Matching the Lists.
A-IV (Length: Digital fibro graph), B-III (Fineness: Gravimetric), C-II (Maturity: Differential dyeing), D-I (Strength: Stelometer).
