Fiber fillings used in garments where warmth is required without increased weight is called:

Correct option is D

Wadding is a soft, fluffy, and insulating material placed between fabric layers in garments, especially in winter wear. Its main function is to trap air, which acts as a thermal insulator, providing warmth without adding bulk or weight. This makes wadding ideal for items like:
· Quilted jackets
· Winter coats
· Sleeping bags
· Padded vests
· Quilts and comforters
Wadding can be made from natural fibers (like cotton or wool) or synthetic fibers (like polyester), each offering different properties in terms of insulation, breathability, and durability.
Information Booster:
The principle behind wadding’s effectiveness is air entrapment. Air is a poor conductor of heat, so when it's trapped between fibers, it forms a barrier that reduces heat loss from the body. This is why garments with wadding are warm yet lightweight.
Wadding is often stitched or quilted into the garment to prevent it from shifting or clumping during use and washing. The loft (thickness) of the wadding can vary based on the degree of insulation required.
Additional Knowledge:
· (a) Lining: Lining is the inner layer of a garment, made of smooth fabric like polyester or satin, that helps the garment slide on easily. It adds comfort and finish, not insulation. It doesn’t trap heat or provide significant warmth.
· (b) Interlining: Interlining is a material inserted between the outer fabric and the lining, often used to give shape or stiffness to parts of a garment like collars, cuffs, or lapels. While some interlinings may offer light insulation, they are not intended for warmth in the way that wadding is.
· (c) Seam binding: Seam binding is a narrow strip of fabric used to encase raw fabric edges within a garment or textile product. It adds strength and a clean finish but has no role in insulation or warmth.
