Flannel

Definition and Overview

Flannel is a woven fabric made by raising the surface of woven textile to create short pile. The fuzzy finish helps trap air, producing a soft touch and a warm appearance. Depending on the fiber type, weave structure, and degree of raising, it can vary widely in thickness and texture.

Those made mainly from cotton may be called “nells,” while relatively firm fabrics made with wool may be called “flannel.” However, these distinctions vary depending on the material, place of origin, and trade custom.

Features

Because the surface pile gently catches the light, it has a calm matte look. It feels gentle against the skin and is generally expected to provide warmth, so it is used as a textile for autumn and winter. It also pairs well with check patterns and yarn-dyed plaid patterns.

On the other hand, the fuzzy surface may become frayed or pill when rubbed. Also, because the pile direction can make colors appear lighter or darker, it is important to align the nap direction of all hardware during cutting.

• Cotton flannel is soft and tends to have a casual look.
• Flannel containing wool has a warmer feel and is also used for more refined applications.
• Blends are sometimes adjusted for durability, ease of handling, and texture.

Main Applications

Light, soft cotton flannel is used for shirts, blouses, pajamas, and children's clothing. Its warmth from the fuzzy finish makes it suitable even for items that come into direct contact with the skin.

For jackets, pants, skirts, dresses, and light outerwear coats, flannel with moderate thickness and body is used. Since applications vary depending on the material composition and industry weight, check the drape and strength required for the item being produced.

Selection and Handling Notes

When selecting, check the composition, thickness, industry weight, one-sided or two-sided fuzzy finish, and pile length. For shirts, compare ease of sewing and feel against the skin; for bottoms and jackets, compare shape retention and resistance to abrasion. For patterned fabrics, also check the pattern direction and pile direction.

Washing and steaming may cause shrinkage, disturbed pile, or changes in texture. Before mass production, perform washing tests and check shrinkage rates according to product conditions. During sewing, the pile may cause seam slippage, so adjust presser foot pressure and feed settings through test sewing.

• Cutting should basically be done in one direction to prevent color differences caused by nap direction.
• Do not press the iron down hard; use a pressing cloth to avoid crushing the pile.
• Washing methods vary depending on composition and finishing, so check the care label and fabric test results.

Differences from Similar Terms

Melton is also a fuzzy wool fabric, but it generally refers to a thick fabric made by fulling the structure tightly and finishing the surface smoothly. Compared with melton, flannel more often has a soft texture with some pile remaining.

Tweed is a general term for wool fabrics with texture created by threads of different thicknesses or colors, and it is not a name determined only by whether the fabric is fuzzy. Flannel is a name derived mainly from its fuzzy surface finish, and it does not independently limit the weave structure or material.

Frequently Asked Questions

Are flannel and nells the same?

Nell is used as one name for flannel and often refers especially to a relatively soft fabric made with cotton and a fuzzy finish. However, the scope of the term varies depending on trade practice, so when placing an order it is important to confirm the composition, thickness, and fuzzy-finish specifications.

Can flannel be machine washed at home?

Whether home washing is possible depends on whether the fabric is mainly cotton or mainly wool, the blend ratio, and the dyeing and finishing conditions. Even cotton flannel may shrink or become fuzzy after washing. When turning it into a product, always make a decision based on the care label and test results for each fabric.
