Water Jet Woven Fusible Interlining 50d.
A fusible interlining is a thin layer made from woven, knitted or non-woven material bonded mechanically or thermally which when fused with fabric panel can give reinforcement, durability and can also stabilize and makes sewing work easier while sewing.
Fused or glued interlinings are the number one thing in the sewing industry today simply because they’re inexpensive and you can produce it on a mass scale very easily and cost effectively. Well the problem with this is that there’s not much flexibility in the garment and you can feel it because it feels less comfortable and it does not stretch when you move.
It is also less breathable and overall it makes the jacket look stiff. For example with this technique you never end up with a nice lapel roll, usually they are quite flat which makes it look less attractive to the wearer. It is also the least durable option, overtime with a few washes it will likely show bubbles on the lapel and on the body of the jacket.
