Question

The twist in a 36 Ne cotton yarn is 15 tpi. The twist multiplier (TM) in cotton system of the yarn (correct to 1 decimal place) is _________.

Hint:

The twist multiplier (TM) is calculated as the twist per inch (TPI) divided by the square root of the yarn count in Ne.

Answer 1

Correct Answer: 2.5

Step 1: Formula for Twist Multiplier (TM). The twist multiplier (TM) is calculated using the formula: \[ TM = \frac{{TPI}}{\sqrt{{Yarn Count}}} \] Where: - TPI is the twist per inch (given as 15 tpi), - Yarn Count is given in Ne (36 Ne). Step 2: Calculating the Twist Multiplier. Substituting the given values: \[ TM = \frac{15}{\sqrt{36}} = \frac{15}{6} = 2.5 \] Step 3: Conclusion. Thus, the twist multiplier (TM) of the yarn is \( \boxed{2.5} \).
