The difference between silk fiber and oak silk fiber. Silk fiber is the only natural silk fiber with practical application. It is made by silk changing mucus and solidifying. Textile fabric manufacturers said that silk fibers are divided into many types according to the food habits of silk, including silk fibers formed from mulberry leaves, silk fibers formed from oak leaves, and other silk fibers formed from cassava leaves, mulberry leaves, and hemp leaves. .
Mulberry silk fiber and oak silk fiber can retain the shape of filament fibers in the filaments formed by bundles, while other wild silk fibers can only be reshaped into short Fibers are processed with textiles. Among the filaments formed by bundling mulberry silk fibers and rubber silk fibers, the filaments of mulberry silk fiber are the most important, accounting for the majority of natural filaments.
Silk structure:
Silk fiber, also known as silk fiber, is the final silk fiber used.
The wire mesh is covered around the wire mesh fibers, and its presence has an important impact on the use, processing and product style of the fibers.
(1) As a protective agent, it can protect silk fibers from mechanical damage during textile processing.
(2) As a clustering agent, it can be used for clustering silkworm filament processing, that is (sao) silk.
(3) Acts as a shape memory agent to lock the deformation of the silk fiber and release it when necessary.
The glue content of each cocoon silk is uneven. The silk spun out at the beginning has low glue content, and the silk spun out at the end has the highest glue content. Silk fiber has a relatively complete fibril structure, which can fully reflect the excellent quality of natural fibers.
Chemical composition:
Silk is a protein fiber and a nitrogen-containing polymer compound.
Object, the single base of its macromolecule is α-amino acid. The general structural formula of α-amino acid is RCH(NH)2COOH. Its amino group is located on the α-carbon atom adjacent to the hydroxy acid, so it is called α-amino acid. According to the general structural formula of silk fibroin molecules, based on the peptide base of the overall macromolecular chain, the connecting side bases are different, which is an important feature of natural protein fibers. There are more than 18 kinds of amino acids that make up silk fibroin.
Collection status:
According to the analysis of molecular conformation changes during the fibrosis process, the fibrotic liquid silk not only has Long-chain molecules in the β conformation also have a certain directionality, so they may form crystals based on the formation of crystal nuclei. Silk is the main body of silk. In addition, it also contains silk and a small amount of wax, fat, inorganic matter, etc.
��Therefore, crystals may be formed based on the formation of crystal nuclei. Silk is the main body of silk. In addition, it also contains silk and a small amount of wax, fat, inorganic matter, etc.
