Silk Raw Material Characteristics

All-natural fiber


The natural fiber included in silk is generally silk fiber, which is a continual long fiber strengthened by the secretion of silk fluid when prepared silkworms develop a cocoon, Castor silk, cassava silk, and so on.

Among them, there are mulberry silk fibers formed from mulberry fallen leaves, tussah silk fibers created from tussah fallen leaves, and also various other wild silk fibers created from cassava leaves, mulberry fallen leaves, as well as castor leaves. Amongst the filament threads formed by packing mulberry silk fibers and tussah silk fibers, the filament yarns of mulberry silk fibers are the most important, accounting for many of the natural filament threads.


Silk framework


Silkworms spew out two silks at the same time, but after solidification, they will certainly combine to form a cocoon silk. Each cocoon silk includes 2 silk fibers bound with each other by sericin, called silk fibroin, that is, silk fiber without adhesive.


Silk fibroin, additionally referred to as silk fibroin, is the silk fiber finally used.
Sericin is twisted around the silk fibroin. Its visibility will have an essential impact on the usage, item as well as handling design of the fiber.


The web content of sericin on each cocoon silk is not uniform, and the content of sericin at the start is low, as well as the material of sericin at the end is the highest possible. Silk fiber has a relatively excellent fibril structure, which can fully share the outstanding quality of all-natural fiber.

The all-natural fiber had in silk is mostly silk fiber, which is a continual long fiber strengthened by the secretion of silk fluid when prepared silkworms create a cocoon, Castor silk, cassava silk, and so on.

Among them, there are mulberry silk fibers formed from mulberry fallen leaves, tussah silk fibers developed from tussah leaves, and also various other wild silk fibers formed from cassava leaves, mulberry leaves, and castor leaves. Each cocoon silk contains 2 silk fibers bound together by sericin, called silk fibroin, that is, silk fiber without glue.
