SEWING NEEDLE WITH OPTIMIZED TIP GEOMETRY AND MICRO-TEXTURED SURFACE.

Abstract

The invention is considered within the scope of textile and garment production technologies and is particularly aimed at improving the structural design of sewing needles used in high-speed industrial sewing machines. Specifically, the goal is to minimize mechanical stress and thermal effects during fabric penetration, regulate friction behavior, and increase overall sewing efficiency by redesigning the geometric form and surface characteristics of the needle tip. Accordingly, the invention relates to a sewing needle developed through the application of biomimetic geometric structures and micro-scale surface textures inspired by nature.
