Yarn

Step 1: Recall formula for yarn count (Metric system).
Count (Nm) = Length of yarn in meters / Weight of yarn in grams.
Here, count is expressed as meters per gram.
Step 2: Substitute values.
Length = 114 m, Weight = 3 g.
So, Count = 114 ÷ 3 = 38 Nm.
Step 3: Correction (English system).
But if we calculate in English system (yards/pound), conversion may be needed.
Here the problem directly suggests a metric count type, so answer = 38.
Step 4: Double-check options.
Given options: 38, 117, 111, 342.
Metric system gives 38.
Step 5: Conclusion.
Therefore, the count is 38.

Step 1: Difference between Worsted and Woolen yarns.
- Woolen yarn: Short fibers, fuzzy, bulky, less smooth, traps air, used in warm clothing.
- Worsted yarn: Long fibers, parallel arrangement, smooth, fine, strong, used for suiting.
Step 2: Importance of combing.
In Worsted yarn spinning, the fibers are passed through a combing process.
This removes short fibers (called noils) and arranges long fibers in parallel form.
This step is not present in Woolen spinning.
Step 3: Option analysis.
- (A) Opening: Present in both woolen and worsted spinning.
- (B) Combing: Correct — extra step in worsted spinning.
- (C) Scouring: Present in both, it cleans wool.
- (D) Spinning: Present in both systems.
Step 4: Conclusion.
Thus, Combing is the additional step in Worsted yarn spinning.

Step 1: Recall formula for equivalent count of folded yarn.
For folded yarn, the reciprocal of resultant count is equal to the sum of reciprocals of the component counts:
Step 2: Substitute given values.
Step 3: Adjust for threefold yarn.
Since it is a threefold yarn, the count of folded yarn = 5s × 2 (plies) = 10s.
Step 4: Conclusion.
Thus, the count of the threefold yarn is 10s.

Step 1: Cotton Count.
Cotton count is defined as the number of hanks of 840 yards that weigh one pound.
Thus, Cotton Count → II.
Step 2: Tex System.
Tex is the weight in grams of 1000 meters of yarn.
Thus, Tex → III.
Step 3: Worsted Count.
Worsted count is based on the number of hanks of 560 yards that weigh one pound.
Thus, Worsted Count → I.
Step 4: Metric Count.
Metric count is defined as the weight in kilograms of 1 km of yarn.
Thus, Metric Count → IV.
Step 5: Conclusion.
Therefore, the correct match is: A - II, B - III, C - I, D - IV.

Step 1: Structure of complex yarns.
Complex yarns are made from more than one strand arranged to give decorative effects.
Corded complex yarns typically use three parts: base yarn, effect yarn, and binder yarn.
Step 2: Function of each part.
- Base Yarn: Provides strength and foundation.
- Effect Yarn: Creates surface texture and decorative appearance.
- Binder Yarn: Holds the base and effect yarns together firmly.
- Fancy Yarn: This is not a separate component; it is the general name for decorative yarns.
Step 3: Option analysis.
- Option 1: A, B and D → Incorrect, because "Fancy yarn" is not a distinct component.
- Option 2: A, B and C → Correct, includes the three real components.
- Option 3: A, B, C and D → Incorrect, again includes Fancy Yarn.
- Option 4: B, C and D → Incorrect, misses Base Yarn.
Step 4: Conclusion.
Hence, corded complex yarns consist of Base, Effect, and Binder yarns.
