Real silk points to silk commonly, include mulberry silk, tussah silk, castor silk, cassava silk to wait. Silk is called "queen of fiber" and is favored by people of all ages for its unique charm. Silk belongs to protein fiber, silk contains 18 kinds of amino acids beneficial to human body.


Silk fiber is the only practical application of natural filament fiber, from silkworm to mucous solidification. Textile fabric manufacturer introduces, silk fiber is divided into a variety because of silkworm feeding nature is different, among them have mulberry silk fiber that feeds mulberry leaf to form, oak silk fiber that feeds oak leaf to form and other wild silk fiber that feeds cassava leaf, mulberry leaf, castor leaf to form. Mulberry silk and tussah silk can retain the form of filament into the filament yarn formed by cluster, while other wild silk fibers can only be changed into short fibers for textile processing. Among the filament yarns made of mulberry silk and tussah silk, the filament yarns of mulberry silk are the most important, which account for most of the natural filament yarns.






Structure of silk






Silk fibroin, also known as silk fibroin, is the ultimate use of silk fibers.


Sericin is wrapped around the silk fiber, and its presence will have an important impact on the use, processing and product style of the fiber.


(1) it can be used as a protective agent to protect fibroin fibers from mechanical damage in textile processing.


(2) it can be used as a cluster agent for the cluster processing of silk filament yarn, i.e., silk reeling.


(3) it can act as a shape memory to lock up the deformation applied to the fibroin fibers and release it when necessary.


The sericin content on each cocoon silk is not even, the silk that starts to spit, sericin content is low, the silk that ends to spit, sericin content is highest. Silk fiber has relatively perfect fibril structure and can fully display the excellent quality of natural fiber.


Chemical composition


Silk belongs to protein fiber, it is a kind of macromolecule that contains nitrogen to combine


The mono - base of the macromolecule is alpha amino acid. The general formula for the structure of alpha amino acids is RCH(NH)2COOH, which is called alpha amino acids because its amino group is located on the alpha carbon atom adjacent to the hydroxyl acid. According to the general structure formula of silk fibroin molecules, different side groups are connected on different peptide groups of the whole macromolecular chain, which is an important feature of natural protein fibers. Silk fibroin is made up of 18 amino acids.


State of aggregation


The analysis of the change of molecular conformation in the process of fiber formation shows that there are not only long chain molecules with beta conformation in the liquid silk of fibrosis, but also a certain degree of orientation, so it is possible to form crystals based on the formation of crystal nucleus. Silk fibroin is the main body of silk, in addition, it also contains sericin and a small amount of wax, fat, inorganic and so on.
