Nahtbild

Nahtbild is a term used in the textile and garment industry to describe the visual and tactile appearance of a seam on fabric. It encompasses how the stitch is formed, how the seam lies against the fabric, the choice of thread, and how the finishing methods translate into the finished look. The concept applies to both the outside and inside of a garment and is influenced by fabric type, construction method, and sewing equipment.

Elements that contribute to Nahtbild include the seam type (for example, flat seams, overlock seams, or bound seams), stitch type and length, thread material and color, tension, and how the edges are finished. The density of stitches, alignment of the seam, presence of topstitching, and the degree of puckering or curling also play a role. In knit fabrics, the stretch and recovery characteristics affect how the seam sits and appears, while in woven fabrics the seam allowances and finishing determine the final look.

Nahtbild is a quality criterion in pattern making, production, and quality control. A favorable Nahtbild is typically characterized by even stitch length, uniform tension, clean edge finishes, minimal puckering, and a neat transition between fabric panels. It is influenced by production parameters such as sewing machine settings, thread choice, fabric thickness, and press methods, and it can be evaluated visually or with standard inspection procedures.

In practice, designers and technicians refer to Nahtbild when selecting seam types and finishes to achieve the desired aesthetics, comfort, and durability for a garment or textile product.
