Interlining is the process of applying an additional layer of fabric such as cotton between the outer fabric and the lining. It has the basic process of giving body, loft and insulation to curtains, quilts, winter jackets or similar items. The method used to add the interlining can vary for different types of applications and ranges from fusion, knit, or woven. Popular materials used include man-made fibers with sufficient insulating qualities, as well as wool and silk.
Here are three of the main types of interfacing available:

Interlining that is thicker is known as bump, which is based on a loose weave made of 20% synthetic fibers and 80% cotton. Due to the high cotton content, it is necessary to use this type of pre-shrunk material to prevent it from getting wet or damp once the manufacturing process is finished. This is a high quality solution to give extra thickness and an excellent option for those who work with a material such as silk. However, it is one of the more difficult materials to use because the loose weave can cause the fibers to dislodge and become quite unstable without careful control. The thickness of this type of material is approximately 0.5 mm and weighs around 400 g/m2.
Wool
The domett type of interlining uses a 100% cotton material with a thick brushed twill weave. It’s made in a variety of weights and is slightly thinner than the shock option. This is a very versatile option and works easily with a wide range of fabrics and is relatively easy to work with. The lighter domett materials are practical for use in home furnishings such as blinds or other areas that rely on pleated sections for tails or trim. The weight of domett can oscillate between 160 g/m2 and 300 g/m2 and the thickness is around 2 or 3 millimeters.
Saril
Saril is a low-cost, synthetic alternative that doesn’t give the best finish and can only be used when absolutely necessary. However, it does have one advantage and that is the ability to prevent shrinkage. If you plan to make something for use in an area that has a humid environment, such as a bathroom or kitchen, this option may be worth using. This material is stitched and is available in a variety of weights similar to the dommett alternative.
