Nonsheer

Nonsheer is a textile term used to describe fabrics that are not transparent. In practice, nonsheer fabrics block light and appear opaque or near-opaque, as opposed to sheer fabrics such as chiffon, georgette, or organza that are intentionally translucent. The term is commonly used in garment specifications and catalogs, though it is less precise than terms like opaque or nontransparent in technical contexts.

Opacity depends on several factors, including fiber content, yarn size, weave or knit construction, fabric weight, and color. Heavier, tightly woven fabrics with dense construction and dark dyes tend to be nonsheer, while lightweight, open-weave fabrics or very light colors can be more translucent. Finishes and the presence of linings or interlinings can also enhance opacity.

Common examples of nonsheer fabrics include cotton broadcloth, poplin, denim, twill, gabardine, canvas, and many wool or synthetic blends. Heavier knits, such as thick jersey, can also be considered nonsheer when their weight and structure prevent light transmission. Conversely, fabrics marketed as sheer are typically thinner, looser, or more delicate in construction.

In practice, nonsheer properties influence garment design, lining choices, and upholstery decisions. Opacity is usually assessed by visual inspection in context, though there are laboratory methods to measure light transmission. There is no universal numerical standard for opacity across brands, so terms like nonsheer, opaque, and nontransparent are often relative to specific products and applications.
