Influence of sewing needle on fiber projecting-out resistance of winter woolen garment

Fiber projecting-out phenomena often occur on the surface of winter woolen garments during wearing,which may be mainly attributed to sewing needles.These phenomena negatively affect the aesthetics and wearability of the garments.According to ″Fabric Test Method for Fiber Projecting-out Resistance of Feather and Down″(GB/T 12705—2009) and the adjusted test parameters based on actual situations,simulation was conducted of fiber projecting-out resulted from all kinds of acting forces such as extrusion,knead,collision and so on of the garment during wearing,and the quantity of projecting-out fiber was counted.The quantity of projecting-out fiber and related rule were studied under conditions of fabrics with different linear densities and different sewing needles used.The results showed that using smaller and round shaped sewing needle is an effective way to reduce the quantity of projecting-out fiber.This technique can be used in the manufacture of winter woolen garments and the fiber projecting-out resistance of the manufactured garments can be effectively enhanced.
