The differences between raw silk and twisted yarn are as follows:
Raw silk is the product obtained after reeling silk from mulberry silkworm cocoons. Commonly known as real silk, machine-reeled silk is also called factory silk, while hand-reeled silk is called native silk. Raw silk after degumming is called finished silk. China has a long history of raw silk production and currently leads the world in output. Silk is soft, smooth, and full to the touch, with good tensile strength, elasticity, a gentle luster, strong moisture absorption, and is non-irritating to the human body. It is a high-grade textile material that can be woven into various silk fabrics with different structures, used for clothing, interior products, handicrafts, decorations, and more. Raw silk also possesses high specific strength, excellent electrical insulation, good thermal insulation, and

Raw silk also has high specific strength, excellent electrical insulation, good thermal insulation, and is flammable but burns slowly. It has important applications in industry, national defense, and medicine, such as making insulating materials, parachutes, and artificial blood vessels.
Twisted yarn refers to yarn in which two cross-sections are relatively rotated, causing the fibers originally parallel to the yarn axis to incline into a helical line. For short fibers, twisting mainly serves to increase yarn strength. For filament yarns, twisting can both increase strength and create a three-dimensional effect. The amount of twist and the matching of twist direction and twist degree in the fabric greatly affect the product's appearance and performance. Therefore, twisted yarn is more expensive than the original drawn yarn. Twist direction refers to the inclination direction of fibers in single yarn or strands in plied yarn after twisting. There are two types: S-twist and Z-twist; S-twist is a forward twist, Z-twist is a backward twist. Every single strand has a twist direction. High-strength yarn refers to yarn that can withstand a tensile force greater than 8 grams per denier. High-strength yarn is suitable for webbing with high tensile requirements, such as webbing used for mountain climbing and rock climbing, or webbing for lifting heavy objects.
