Quilt Batting

Definition and Overview

Quilt batting is a filling material inserted inside garments. By creating a layer that holds air, it helps retain heat and gives garments loft and soft thickness. Sheet-type batting is cut and used, while fiber-fill type batting is packed in according to the area.

Interfacing is also a secondary material used on the inside of garments, but it differs in that its main purpose is to maintain shape and reinforce. Quilt batting is mainly intended to provide warmth, cushioning, and volume, and it is generally not required to be as stiff or firm as interfacing.

Areas Used and Functions

It is used in the body and sleeves of coats, blousons, and vests. In quilted constructions, the outer fabric, batting, and lining are layered and sewn together to maintain warmth and achieve both function and design while preventing the batting from shifting.

Outside of apparel, it is also used in the body, handles, and other small items such as bags and pouches where protection is needed. Thin batting is suitable when you want to add a soft feel and moderate loft without greatly changing the thickness.

• Add warmth
• Create loft and three-dimensionality
• Absorb shock
• Make the thinness of the outer fabric and stitching less noticeable

Materials and Types

Materials include polyester, cotton, and wool, and the texture and function vary depending on the fiber type, fiber thickness, loft, and sheet density. Polyester-based types are often used in products that require lightness and easy handling, while natural-fiber types are chosen for applications that want to make use of the material's texture.

Forms include nonwoven sheet types made by entangling fibers, fiber-fill types, and types in which the fibers are fixed with adhesive. There are also quilt battings with an adhesive layer on one side or both sides that can be temporarily bonded or bonded to the outer fabric or lining.

How to Choose and Sewing Precautions

If a thin, soft outer fabric is paired with thick, stiff batting, the surface may pucker or the seams may be strained. Check the outer fabric's thickness, stretch, drape, and the warmth required for the product, then choose by combining the batting's thickness, density, resilience, and firmness.

Batting tends to shift during cutting and sewing, so stabilize its position with temporary basting, quilting, or topstitching. In thick materials, seam allowances tend to pile up and become bulky, so check the seam allowance finish, the selection of machine needle and thread, and the sewing conditions at stepped areas in advance.

For adhesive types, it is important to check the heat resistance of the outer fabric and its compatibility with surface finishes, and perform test bonding. If heat or pressure is insufficient, it may cause peeling, and excessive conditions may lead to deformation of the outer fabric, shine, or adhesive bleed-through.

Frequently Asked Questions

What is the difference between quilt batting and interfacing?

Quilt batting is a filling material used to provide warmth, loft, and cushioning. Interfacing, on the other hand, is a reinforcing material used to maintain the shape of collars, front edges, facings, and similar parts, and to prevent stretching and distortion. Depending on the product, both may be used in different areas.

Can quilt batting be bonded to the outer fabric?

If the batting has an adhesive layer, it can be bonded, but not all batting is for bonding. Depending on the outer fabric material and finish, it may change under heat, so perform test bonding under different temperature, time, and pressure conditions, and check the appearance and whether peeling occurs.

How is batting thickness determined?

It is determined based on the required warmth, the silhouette you want to achieve, the thickness of the outer fabric and lining, and the thickness of seam allowances that can be sewn. Even with the same thickness, loft and firmness differ depending on the material and density, so it is important to check with a sample actually layered and sewn.
