Which fabric has a low melting point?

Which fabric has a low melting point?

• A. Silver-pile knit
• B. Pique knit
• C. Rib knit
• D. Interlock

Answer: (C)

Melting point in fabrics is driven by the fiber chemistry. Natural fibers like cotton or wool don’t melt; they burn or char instead. Thermoplastic synthetic fibers, such as polyester, have a defined melting point and will soften or melt at relatively low temperatures. Rib knit is commonly made from polyester or polyester blends, so its fibers tend to have a lower melting point compared with the natural-fiber knits or the metallic-pile option. The other fabrics are typically cotton-based or involve materials that don’t melt at low temperatures in the same way, so they won’t exhibit a low melting point.
