1. What is the primary function of a loom in textile production?
A. Dyeing fibers
B. Interlacing warp and weft yarns to form fabric
C. Cutting finished garments
D. Spinning yarns
A loom’s fundamental role is to interlace warp and weft yarns under
tension in order to produce woven fabric.
2. Which part of the loom holds the warp yarns under tension?
A. Shuttle
B. Beat-up
C. Warp beam
D. Take-up roll
The warp beam is the component that holds the supply of warp yarns
and maintains tension as the fabric is woven.
3. What is the function of heddles in a loom?
A. To apply dye to yarns
B. To guide warp yarns and facilitate shed formation
, C. To measure fabric width
D. To wind weft yarn
Heddles are used to control and guide the individual warp yarns and
assist in forming the shed for weft insertion.
4. In weaving terminology, the “shed” refers to:
A. The lint collection tray
B. The gap between raised and lowered warp yarns
C. The finished edge of fabric
D. The weft insertion path
The shed is the space created when warp yarns are separated to
allow the weft thread to pass through.
5. Which mechanism is responsible for beating the weft into place?
A. Warp stop motion
B. Reed extension
C. Reed
D. Take-up motion
The reed pushes the newly inserted weft yarn securely into position
against the fell of the cloth.
6. What is the safety purpose of the warp stop motion?
A. To cut excess warp
B. To stop the loom if a warp yarn breaks
C. To control loom speed
D. To adjust weft tension
Warp stop motion prevents defects by halting the loom when a warp
break is detected.
7. Which loom component guides the shuttle across the shed?
A. Warp beam
B. Shuttle race
C. Reed
, D. Tension box
The shuttle race provides the track along which the shuttle travels
during weft insertion.
8. What type of loom uses rapier mechanisms instead of shuttles?
A. Circular loom
B. Shuttleless loom
C. Backstrap loom
D. Handloom only
Rapier looms are categorized under shuttleless looms and use
retractable arms to insert weft yarn.
9. Which defect is caused by improper tension in warp yarns?
A. Bow
B. Skew
C. Slubs
D. Barré
Uneven warp tension can result in skewed fabric where the warp and
weft are misaligned.
10. What does the term “pick” refer to in weaving?
A. A warp yarn
B. A fabric imperfection
C. A single weft insertion across the loom
D. A heddle type
A pick is one pass of the weft yarn across the warp threads.
11. The take-up motion on a loom is responsible for:
A. Cutting warp yarns
B. Winding woven fabric onto the cloth beam
C. Feeding weft yarn
D. Tensioning the heddles
