Question

Determine the correctness or otherwise of the following Assertion [a] and Reason [r]
Assertion: In shuttle loom, late shedding is preferred for filament weaving.
Reason: In late shedding, the timing of shed dwell matches with the timing of shuttle travel through the shed, and therefore, it minimizes the rubbing of warp yarns.

• A. Both [a] and [r] are true and [r] is the correct reason for [a]
• B. Both [a] and [r] are true and [r] is not the correct reason for [a]
• C. Both [a] and [r] are false
• D. [a] is true but [r] is false

Hint:

In shuttle looms, late shedding reduces the rubbing of warp yarns, which is crucial for filament weaving to avoid damage to the delicate yarns.

Answer 1

The Correct Option is A

In shuttle looms, late shedding is indeed preferred for filament weaving because it reduces the rubbing of warp yarns. Late shedding allows the shuttle to pass through the shed before the warp yarns are fully raised, which minimizes friction between the shuttle and the yarns. This is particularly important in filament weaving where the delicate yarns are prone to damage. The assertion (a) is correct, and the reason (r) provided correctly explains why late shedding is beneficial in this context. Thus, both the assertion and the reason are true, and the reason is the correct explanation for the assertion. Final Answer: \boxed{(A) Both [a] and [r] are true and [r] is the correct reason for [a]}
