Interlining is a popular option to enhance window treatments like curtains or blinds to give an extra layer of thickness. Many fabrics can appear quite lifeless and thin on their own, but adding the extra layer can have a dramatic impact for the more sumptuous look. The interlining is not only used to improve the all-round look, but also to make the curtains a lot more insulating.
The major types of interlining consist of saril, which is made from polyester and domett and bump which is made from cotton.
Saril is one of the most cost-effective interlining options, but it does lack drape qualities, so is not a practical choice in all situations. This is a stitch bonded fabric with fibers joined using repeated rows of small stitches. The actual weight is quite consistent with cotton substitutes. A practical benefit of saril over domett and bump is the ability to resist shrinking in a moist environment. This makes it useful for any items used in the bathroom or kitchen.
Domett is a type of cotton twill fabric that is heavily brushed and slightly thinner than bump. It is available in a choice of weights to make it more versatile to use. This interlining option is one of the easiest to work with. A popular area to use domett is curtains, blinds, or other areas with pleated features, such as tails and swags. The thickness of domett is in the region of 2mm and the weight can range from 160g / m2 to 300g / m2.
Bump is a loosely woven and thick fabric that is perfect for various types of interlacing. It is made from 20% synthetic fibers and 80% cotton. This type of fabric is likely to shrink in the moisture atmosphere so it is more practical to use pre-shrunk. This is a high-quality option and certain to give the best looking finish for a set of curtains. Also, it is practical to pair with thin fabrics such as silk. However, this is one of the most difficult interlining options to work with. The thickness is about 0.5mm and weight is in the region of 400g / m2.
While the interlining does do a lot to improve the curtains and blinds, it can have a significant impact on the price. This relates to the increased time to make the item and the greater fabric used. But, in most cases, it does lead to the finished item with the far superior finish and insulating qualities.
