Question

What will be the tightness factor of the plain single jersey knitted with 64 tex yarn and 1.5 cm loop length?

• A. 96
• B. 42
• C. 5.3
• D. 2.3

Hint:

Tightness factor formula : \(\frac{\sqrt{\text{Tex}}}{\text{Loop Length (cm)}}\)

Answer 1

The Correct Option is D

Step 1: Defining Tightness Factor: The tightness factor (TF) of a knitted fabric is a measure of how tightly or loosely the loops are packed. It's calculated using the yarn count (in tex) and the loop length (in cm): \[ \text{Tightness Factor (TF)} = \frac{\sqrt{\text{Tex}}}{\text{Loop Length (cm)}} \]
Step 2: Calculate the value: Yarn Count (Tex): 64 tex Loop length: 1.5cm \[ \text{Tightness Factor (TF)} = \frac{\sqrt{64}}{1.5} = \frac{8}{1.5} = 5.33 \] Rounding it to the nearest value, we get 5.3.
