The difference between silk and mulberry silk
Silk usually refers to silk, which includes castor silk, tussah silk, mulberry silk and cassava silk.The filaments made by holding several cocoon filaments together and sticking them together with mulberry silk as raw material are called silk.Mulberry silk is a continuous long fiber formed by the solidification of the silk secreted by mature silkworms when they cocoon. Mulberry silk is also called natural silk.
Mulberry silk is one of the earliest animal fibers used by humans.Mulberry silk is a natural animal protein fiber and is the main raw material for silk weaving.The difference between silk and mulberry silk is that silk is synthesized on the basis of mulberry silk.Using mulberry silk as raw material, silk is a fabric made after processing.
The following methods can be used to identify silk and mulberry silk：
1. Price identification: The price of silk fabrics is about twice that of chemical fiber and artificial silk satin.
2. Product number identification: Domestic satin is a unified product number composed of 5 Arabic numerals. The first digit of these 5 digits from the left represents the fabric material number. All silk fabrics are “1”, chemical fiber fabrics are “2”, blended fabrics are “3”, tussah silk fabrics are “4”, and rayon fabrics are “5”.
3. Identification of luster and feel: Spread the sample evenly to see its appearance. The silk has light-absorbing properties, looks smooth and does not afford a mirror surface, has an elegant and soft luster, is pearl-bright, and feels soft and elegant. The silk thread is denser, and there will be wrinkles when grasped by hand. The higher the purity and the greater the density, the better the silk feel; Although the simulation silk fabric has been de-hardened, it feels softer, but the silk surface is dark and has no pearl luster; the chemical fiber fabric is shiny and bright, dazzling, and feels stiffer.In addition, silk products should feel slightly scratched. Rubbing the two layers of fabric will produce a “silk buzzing” sound, while fabrics from other raw materials do not.
4. Burning: Take out part of the yarn and burn it. The silk cannot see the open flame. It has the smell of burning hair. The silk is gray and black particles, which can be crushed by hand; The simulation silk is caught in fire and has a plastic smell. After the fire is extinguished, hard glue will be left on the edge.
