* CDXA Elastic laminate composite: A breathable, stretch, 3-layer laminate consisting of a nonwoven base, elongated strands of Lycra® XA® ( a man-made elastomeric fiber), and a nonwoven cover, bonded together with a hot melt adhesive. There are two types: MDXA in which the Lycra XA strands are laid down in the machine direction, which gives the resulting laminate good elasticity in the machine direction; and CDXA in which the elongated strands are laid down in the cross-machine direction, which gives the resulting laminate good stretch and recovery in the cross direction plus strength and stability in the machine direction. Both of these elastic laminate composites can be tailored to suit individual applications. | * CDXA Elastic laminate composite: A breathable, stretch, 3-layer laminate consisting of a nonwoven base, elongated strands of Lycra® XA® ( a man-made elastomeric fiber), and a nonwoven cover, bonded together with a hot melt adhesive.
