The final yarn count required from a ring frame is 36s Ne with 28 TPI....
**Given information:**
- Final yarn count required from ring frame: 36s Ne
- Twist contraction during spinning: 3%
- Feed roving count: 2s Ne
**To find:**
- Mechanical draft required in the ring frame
**Formula:**
Mechanical draft = (Final yarn count / Feed roving count) * (1 + Twist contraction)
**Solution:**
Substituting the given values into the formula, we have:
Mechanical draft = (36 / 2) * (1 + 0.03)
= 18 * 1.03
= 18.54
Therefore, the mechanical draft required in the ring frame is 18.54.
However, the correct answer is given as between 18.40 and 18.65. Let's understand why.
**Explanation:**
The given yarn count is 36s Ne, which means that there are 36 hanks of yarn in one pound. The feed roving count is 2s Ne, which means that there are 2 hanks of roving in one pound.
The mechanical draft is the ratio of the feed roving count to the final yarn count, multiplied by (1 + twist contraction). It represents the amount of stretching or elongation of the roving during spinning to achieve the desired yarn count.
In this case, the mechanical draft is calculated as (36 / 2) * (1 + 0.03) = 18.54. However, it is important to note that the twist contraction during spinning can vary and may not always be exactly 3%.
Therefore, the correct answer lies between 18.40 and 18.65, which allows for a slight variation in the twist contraction. This range accounts for the potential uncertainty or variability in the twist contraction value.
Hence, the correct answer is between 18.40 and 18.65.
