Question

The nonwoven technology which uses high-pressure water jets is

• A. Needlepunched
• B. Spunlacing
• C. Spunbonding
• D. Meltblowing

Hint:

Spunlacing is a nonwoven technology where water jets are used to entangle fibers and create a fabric without using heat or adhesive.

Answer 1

The Correct Option is B

The nonwoven technology that uses high-pressure water jets is known as spunlacing. This process involves using jets of water to entangle fibers and form a fabric. The fibers are not bonded by adhesives or heat but are mechanically bonded by the force of the water jet, creating a fabric with good strength and softness. Spunlacing is used to produce soft and breathable fabrics that are often used in hygiene products, medical fabrics, and wipes.
In comparison, other nonwoven technologies, like needlepunched (A), use needles to entangle the fibers, and spunbonding (C) uses continuous filaments to form fabrics, which does not involve high-pressure water jets. Meltblowing (D) uses hot air to form fibers, which is also not related to water jets.
Therefore, the correct technology using high-pressure water jets is spunlacing. Final Answer: \boxed{(B) Spunlacing}
