64% Polyester 36% Viscose Bump with Polyester Cotton Twill.
Bump curtain interlining is the perfect interlining to provide thermal and sound protection to windows and many other projects.
This interlining is ideal for larger curtains for doors and large windows and also to add body to lightweight fabrics that are going to be used for furnishings.
It has the added benefit of being bonded with a smooth Twill weave sateen lining attached, so does away with having to stitch the layer to the lining.
Its polyester viscose construction may be better for a person who is sensitive to dust as this fabric is less fibrous than the cotton interlining.
