Answer: D. Nonwoven. Nonwovens offer scalable web production and can be designed to distribute liquid or provide a barrier.
Which geosynthetic is intended mainly as a low-permeability fluid barrier?
A Uncoated geotextile
B Loose filter felt
C Open geogrid
D Geomembrane
Answer: D. Geomembrane. A geomembrane provides containment by resisting fluid movement through a continuous barrier.
Which property describes a sports textile’s ability to move sweat along the fabric?
A Wicking
B Calendering
C Seam slippage
D Bleach exhaustion
Answer: A. Wicking. Wicking moves liquid through small spaces by capillary action.
What segment includes fabrics designed to protect workers from industrial hazards?
A Sportech
B Protech
C Packtech

Answer: B. Protech. Protech groups textiles intended to protect people or equipment from specified hazards.
What surrounds and holds the reinforcing fibres in a composite?
A Spindle
B Matrix
C Selvage
D Squeegee
Answer: B. Matrix. The matrix binds the fibres and helps transfer stress to them.
What is the function of a water-resistant backsheet in an absorbent hygiene article?
A Collect liquid at skin
B Raise surface friction
C Add permanent creases
D Limit outward leakage
Answer: D. Limit outward leakage. The backsheet acts as a barrier to fluid leaving the product through its outer side.
Which group includes architectural textile membranes for roofs or facades?
