Question

The yarns produced by splitting or slitting of sheets of material are called as ...........

• A. Spun Yarns
• B. Combed Yarns
• C. Tape Yarns
• D. Worsted Yarns

Hint:

Tape yarns = slit polymer films → narrow strips → stretched → strong flat yarns.

Answer 1

The Correct Option is C

Step 1: Recall tape yarn production.
Tape yarns are special flat yarns created by slitting polymer sheets or films (like polypropylene or polyethylene) into narrow strips.
These strips are then stretched or drawn to increase strength and molecular orientation.
Step 2: Importance in textiles.
Tape yarns are strong, light, and ribbon-like, making them very useful in woven sacks, ropes, nets, and packaging.
They differ from conventional spun yarns because they are not twisted bundles of fibers but continuous strips.
Step 3: Option analysis.
- (A) Spun Yarns: Made from staple fibers twisted together, not by slitting sheets.
- (B) Combed Yarns: Produced by combing longer fibers to make smooth yarns. Not correct.
- (C) Tape Yarns: Correct, since they come from splitting polymer films.
- (D) Worsted Yarns: Made from wool fibers after combing and spinning, not by slitting.
Step 4: Conclusion.
Hence, yarns produced by splitting or slitting sheets are called Tape Yarns.
