Interlinings: What Are They Used For?
Share on:
Currently, to maintain the shape of the various sections of a garment, a fabric is used that is permanently secured between two layers of fabric in a garment through fusing or sewing; this is known as interfacing. It provides insulation and weight, as well as improving the drape of the fabric, which helps protect delicate fabrics.
Types of Interlinings
There are two types of interfacing, each with unique characteristics that meet different sewing needs:
Sewn-in interfacing
This type of interfacing has a plain weave construction. It is placed between two pieces of fabric and secured with stitches. It is important to note that, before joining the fabrics, you must ensure that the interfacing is the same size as the other pieces of fabric to be joined.
In terms of construction, for lighter interfacings, cotton warp and weft threads can be used, which provide a soft feel on both sides; whereas to prevent the garment from wrinkling and to ensure better shape retention, a cotton warp and a viscose weft are typically used.
Heat-activated interfacing
This type of interlining is made from woven fibers or nonwoven materials, which are bonded together through thermal or chemical processes. It is placed between the layers of fabric and bonded by fusion, which requires the application of pressure and heat for a specific period of time.
The fibers used can be polyester, rayon, or nylon; furthermore, the way the fibers are arranged affects the strength and characteristics of the interfacing.
Functions of Interlining
- To hold a garment in place.
- To help the garment retain its shape.
- It reinforces parts of the garment, making it stronger and more attractive.
- It improves the garment’s performance during use.
Applications and Uses of Interlinings in Clothing
They are mainly used on collars, cuffs, jackets, as trims on outerwear, coats, shoes, bags, and other items; however, they can also be used to protect fabrics, especially those exposed to direct sunlight, such as curtains.
When it comes to delicate fabrics, such as velvet or silk, they can be damaged by handling or constant use; therefore, most tailors use interfacing to extend the garment’s lifespan.
How do you choose a type of interfacing?
The type of interfacing should be chosen based on the fabric to be used; if you’re working with a heavy fabric such as denim or wool, consider using an interfacing with a cotton warp and a viscose weft; however, if you’re using a lightweight fabric such as silk, use a lightweight interfacing. It’s also important to know the type of garment you’re making, since the amount of interfacing used varies depending on whether it’s a ready-made garment or a custom-made garment.
Conclusion
Interlinings are widely used in garment manufacturing; thanks to the additional properties they impart to garments, they enable high-quality workmanship. Furthermore, there are different ways to use them depending on the specific needs.
