The main break of wool fiber is a cortical layer of cortical cells. Wool cortex cells contain high sulfur and low sulfur two proteins, the former is the main component of the matrix, the molecular chain was amorphous curly; the latter has a helical structure of the molecular chain, composed of basic fibroblasts in cortical cells (protofibril) . The basic fibrils then form microfibrils and the microfibrils further make up the fibrils. A variety of fibrils are buried in the tomb, fibrils and Kam between the disulfide bond can be connected. Some research data indicate: 0 cortical fibrils, a diameter of about 0.25m, a diameter of microfibrils 7.5nm (75A), the basic fibril diameter of about 2nm
Chemical fiber felt is a general term for fibers made from polyester, polypropylene, acrylic, imported fiber as raw material, and chemical fiber made from natural or synthetic polymer material through chemical or physical processing. Due to the different sources of macromolecular compounds used, it can be divided into synthetic fibers made from natural macromolecule materials and synthetic macromolecule materials. Referred to as chemical fiber.
Thus, in order to ensure that the chemical fiber felt in use can be maintained in good condition on a regular basis need to let it rest for a while to ensure that it can restore flexibility. According to the above characteristics, if carefully compared in use you can choose to high-quality chemical fiber felt.
