Nainsook A lightweight plain weave cotton fabric, usually finished to create a luster and a soft hand. Common end-uses are infants' wear, blouses, and lingerie.
Nano-fiber Nano refers to 1 billionth of a meter, or 1 x 10-8 centimeter. 150,000 strands of a nano-fiber can fit across a human hair.
Nano-technology Complex technology that involves nano-size materials and combines science such as biology, chemistry and physics and engineering.
Nap A fuzzy, fur-like feel created when fiber ends extend from the basic fabric structure to the fabric surface. The fabric can be napped on either one or both sides.
Napping The raising of fibers on the face of the goods by means of teasels or rollers covered with card clothing (steel wires) that are about one inch in height. Action by either method raises the protruding fibers and causes the finished fabric to provide greater warmth to the wearer, makes the cloth more compact, causes the fabric to become softer in hand or smoother in feel, increases durability and covers the minute areas between the interlacings or the warp and the filling.
Net An open mesh fabric of rayon, nylon, cotton, or silk; made in a variety of geometric-shaped meshes of different sizes and weights, matched to various end-uses. The net is made by knotting the intersections of thread or cord to form the mesh.
Net An open fabric, which is created by connecting the intersections in a woven, knitted, or crocheted construction to form a mesh-like appearance that won't ravel. End-uses include veils, curtains, and fish nets.
Ninon A lightweight, plain weave, made of silk or manufactured fibers, with an open mesh-like appearance. Since the fabric is made with high twist filament yarns, it has a crisp hand. End uses include eveningwear and curtains.
Nonwoven Fabric A textile structure held together by interlocking of fibers in a random web, accomplished by mechanical, chemical, thermal or solvent means. Generally, crimped fibers that range in length from 0.75 to 4.5 inches are used.
Novelty Yarn A yarn that is intentionally produced to have a special or unique effect. These effects can be produced by twisting together uneven single yarns, by using yarns that contain irregularities, or by twisting yarns that contain a color variance. A slubbed yarn is an example of a novelty yarn.
Nylon Produced in 1938, the first completely synthetic fiber developed. Known for its high strength and excellent resilience, nylon has superior abrasion resistance and high flexibility.
Nytril A manufactured fiber, most often used in sweaters or pile fabrics, where little or no pressing is recommended, as the fiber has a low softening or melting point. However, it has also been successfully used in blends with wool for the purpose of minimizing shrinkage and improving the shape retention in garments.
