Fabric lots are checked against agreed width, weight and defect limits. Where are those requirements recorded?
A Product specification
B Operator attendance sheet
C Machine repair manual
D Shipping forecast
Answer: A. Product specification. A product specification states the required characteristics, tolerances and acceptance criteria.
The left and right panels of a garment show different shades. Which records should be checked first?
A Lab dryer speed
B Carton print resolution
C Panel dye lot matching
D Needle position only
Answer: C. Panel dye lot matching. Mixing parts from different shade or dye lots can create visible mismatch within a garment.
Choose a selection method that gives each equal-sized fabric roll an equal chance of inclusion.
A Choose the nearest roll
B Choose only first rolls
C Choose the cleanest rolls
D Simple random sampling
Answer: D. Simple random sampling. Random selection from the full roll list can give each roll an equal chance to be selected.
Name the check that compares a test instrument against a known reference.
A Shade grouping
B Packing
C Pattern grading
D Calibration
Answer: D. Calibration. Calibration compares indications with reference values and can establish measurement error.
Before releasing a finished lot, what is final inspection used to do?
A Adjust yarn winding speed
B Confirm release requirements
C Set initial fibre blend
D Create the first pattern
Answer: B. Confirm release requirements. Final inspection checks finished goods against the release criteria.
On a woven fabric, a continuous lengthwise flaw produced by an absent warp yarn is called what?
A Course barré
B Missing pick
C Seam opening
D Missing end
Answer: D. Missing end. Warp ends run lengthwise. A missing one can leave a continuous lengthwise line.
What describes the allowable difference from a target dimension?
A Tolerance
B Defect classification
C Calibration
D Median
Answer: A. Tolerance. Tolerance states how much variation from a target is acceptable for the characteristic.
Raised small balls of entangled fibres are found after routine care. Identify the defect.
A Bow
B Shade band
C Needle line
D Pilling
Answer: D. Pilling. Pilling creates small fibre balls that remain attached to the fabric surface.
For a count of faulty units, how is a garment with three imperfections normally counted?
A As no defect at all
B As three separate units
C As three garment lots
D As one nonconforming unit
Answer: D. As one nonconforming unit. A unit count counts each nonconforming garment once. A defect count can count several faults on that garment.
What does inspection of incoming yarn aim to detect before manufacture?
A Carton delivery schedules
B Nonconforming purchased material
C Software update needs
D Customer return causes only
Answer: B. Nonconforming purchased material. Incoming inspection can identify yarn that does not meet quality requirements before it enters production.
When weft threads curve across the width, which defect is present?
A Dropped stitch
B Puckering
C Bow
D Skew
Answer: C. Bow. Bow is curvature across the width. Skew describes an angular displacement of a yarn or course line.
Why are nonconforming goods often physically separated and identified?
A Improve dye fixation
B Increase roll width
C Prevent unintended use
D Remove every mark
Answer: C. Prevent unintended use. Segregation keeps suspect goods from being mixed with accepted production.
Which identifying record helps trace a fault to a particular dye batch?
A Room humidity label
B Machine paint colour
C Fabric retail brand only
D Dye lot number
Answer: D. Dye lot number. A dye lot number links the fabric or garments to the batch where the colour was processed.
Find the woven fault caused by an absent weft insertion.
A Uneven nap
B Missing pick
C Missing end
D Dropped loop
Answer: B. Missing pick. A pick is one insertion of weft across the width, so its absence leaves a crosswise fault.
When only selected units are examined, what is the group selected called?
A Population
B Tolerance
C Sample
D Specification
Answer: C. Sample. A sample is the subset taken from the full lot or population for inspection.
A corrective action should target which aspect of a recurring quality problem?
A Underlying cause
B Only its first symptom
C The product name
D Random retesting alone
Answer: A. Underlying cause. Corrective action addresses the cause to reduce the chance of recurrence.
Which check takes place while fabric is still being made?
A In-process inspection
B Final shipment inspection
C Post-sale warranty review
D Warehouse stocktaking
Answer: A. In-process inspection. In-process inspection identifies defects while there is still time to stop, adjust or correct production.
Which sampling action reduces the risk of checking only an unusually clean region of a roll?
A Select only bright areas
B Sample several roll locations
C Inspect only the leader
D Choose the smoothest edge
Answer: B. Sample several roll locations. Checking several locations improves coverage of variation along the roll and across the fabric.
Notice that a normally crosswise weft line now runs at a straight angle to the selvage. Which defect fits?
A Skew
B Bow
C Fabric glazing
D Needle cut
Answer: A. Skew. Skew shifts the yarn or course alignment so it no longer lies at the intended right angle to the edge.
For a width specified as 150 ± 2 cm, which reading exceeds the upper limit?
A 150 cm
B 152 cm
C 153 cm
D 148 cm
Answer: C. 153 cm. The upper specification limit is 152 cm. A reading of 153 cm exceeds it.
Repeated measurements under the same conditions agree closely. Which characteristic describes this?
A Large between-site variation
B High bias
C High nonconformance
D Repeatability
Answer: D. Repeatability. Repeatability concerns agreement among measurements made under essentially the same conditions.
Assigning penalty points to faults during fabric inspection helps assess what?
A Steam pressure regulation
B Overall fault burden
C Fabric shipment cost
D Yarn twist direction
Answer: B. Overall fault burden. A grading system assigns points to faults so their burden can be compared on a defined area basis.
What is a rework instruction intended to achieve?
A Skip the release check
B Add random inspection data
C Bring units into conformance
D Change all specifications
Answer: C. Bring units into conformance. Rework corrects a recoverable fault so the item can be evaluated against requirements again.
After a corrective action, what step checks that the problem actually improved?
A Verify subsequent performance
B Remove all previous records
C Increase defect tolerance
D Accept the next lot automatically
Answer: A. Verify subsequent performance. Follow-up measurements determine whether recurrence declined and the action was effective.
Distinguish quality control from production scheduling. Which activity is quality control?
A Allocate staff holidays
B Compare results with requirements
C Assign daily dispatch routes
D Order a larger warehouse
Answer: B. Compare results with requirements. Quality control checks whether the product or process meets stated requirements.
