Felt

Definition and Overview

Felt is a nonwoven fabric made by entangling fibers. The typical raw material is wool, but polyester, acrylic, and other synthetic fibers, or blends of these, are also used. It does not have warp and weft like woven fabrics, or stitches like knits.

Wool felt sometimes uses the scale-like structure called scales on the fiber surface to entangle the fibers by applying moisture, heat, and pressure. For synthetic fibers, needle punching and similar methods that entangle the fibers with needles are commonly used.

Characteristics

Its surface has a fuzzy, matte appearance, and its soft, warm texture is a defining feature. Depending on thickness and density, it ranges from thin and supple to firmer types that hold their shape well. In general, the fact that cut edges do not fray easily also makes it easy to handle.

Because of its air-retaining structure, felt made mainly from wool can provide heat retention and cushioning. On the other hand, stretchability, water absorbency, resistance to friction, and pilling tendency vary depending on the raw materials, production method, and density, so it is important to check actual samples for each application.

Main Applications

In apparel, it is used for hats, bags, some parts of shoes, coat and jacket decoration, and appliqués. Since it can be used in design without finishing the cut edges, it is also suitable for craft-like accessories and kids' items.

Thick, firm types are also used for pouches, boxes, interior miscellaneous goods, and cushioning materials. Its warm appearance makes it a good match for fall and winter planning, while thin products and synthetic types are also chosen for uses that are not limited to a particular season.

• Hats, bags, and pouches
• Patches, appliqués, and garment decoration
• Hardware for shoes and fashion accessories
• Interior accessories and storage items
• Cushioning and protective materials

Selection and Handling Precautions

When selecting, check the raw material, thickness, industry weight, density, firmness, surface fuzz, and color. For three-dimensional shaping or self-supporting applications, check firmness and recovery; for uses that touch the skin, check for itchiness and shedding fuzz. Before sewing, also test how visible the needle holes are and how much the stitches sink in through prototyping.

Felt containing wool may shrink, harden, or lose its shape due to washing, friction, or heat. Washing methods vary depending on the blend ratio and finishing, so always follow the care label. In sewing, needle breakage and feeding problems can occur in thick areas, so adjust the needle, thread, and presser foot pressure through test stitching.

Differences from Similar Terms

Felt is a nonwoven fabric that is not made by weaving or knitting. Melton is generally a wool woven fabric that has been fullered to create a dense surface, and it differs from felt in that it has a woven structure. Even when the appearance is similar, cut edges, stretch, and behavior during sewing are not the same.

Nonwoven fabric is a broad term for materials that are sheeted without weaving or knitting fibers. Felt is treated as one type of nonwoven fabric, but depending on the application and manufacturing method, some nonwovens are not called felt. It is also important to note that this is a term indicating structure and production method, not just a material name.

Frequently Asked Questions

Can felt be washed?

Whether it can be washed depends on the raw material, blend ratio, density, and finishing. In particular, items containing wool may shrink or deform due to moisture, heat, and friction. Do not judge whether it can be washed at home based only on the material name; check the care label on the product or fabric and the test results.

Do cut edges of felt fray?

Because felt is not a structure made by weaving or knitting threads, cut edges generally do not fray into threads easily. However, surface fuzz may shed, and with thin or low-density products, the edges may become distorted. Check the condition during cutting and use before mass production.

What is the difference between felt and melton?

Felt is a nonwoven fabric made by entangling fibers, whereas melton is generally a fabric made by fulling woven cloth to increase density. Both have a thick, warm appearance, but they differ in whether they have a structure, edge behavior, grain direction, and changes during sewing and washing.
