Brushed Microfiber 4 in pillowcases manufacturers take you to understand the preparation method of conventional microfiber
Brushed Microfiber 4 in pillowcases manufacturers tell you that conventional microfibers are mainly divided into two types: filament and short filament. Different fiber types have different spinning forms.
Brushed Microfiber 4 in pillowcases manufacturers tell you that conventional microfibers are mainly divided into two types: filament and short filament. Different fiber types have different spinning forms. The manufacturer of Brushed Microfiber 4 in pillowcases tells you that the spinning forms of conventional microfiber filaments mainly include direct spinning method and composite spinning method. Spinning method, blend spinning method, etc.
1. Direct spinning method This method is a spinning technology that uses a traditional melt spinning process to prepare microfibers with a single raw material (polyester, nylon, polypropylene, etc.). The Brushed Microfiber 4 in pillowcases manufacturer tells you that the process is simple and easy to operate. It is convenient, but it is prone to breakage in the process of preparing fibers, and the spinneret holes are easily blocked.
2. Composite spinning method This method uses composite spinning technology to prepare composite fibers, and then uses physical or chemical treatment to separate the composite fibers in multiple phases, thereby obtaining ultra-fine fibers. The success of composite spinning technology marks ultra-fine fibers. The real beginning of fine fiber development.
3. The manufacturer of Brushed Microfiber 4 in pillowcases tells you that the conventional alkali reduction method is mainly aimed at polyester fibers, and uses dilute alkali solution to treat polyester fibers to achieve the purpose of thinning fibers.
4. Jet spinning method This method mainly uses polypropylene as the spinning object, and sprays low-viscosity polymer melt into short fibers through jet air.
5. Blended spinning method This method is to melt and blend two or more polymer materials for spinning. The manufacturer of Brushed Microfiber 4 in pillowcases tells you that due to the differences in physical characteristics such as different component contents and viscosity , the separation of components can be achieved by using a solvent, and discontinuous ultrafine short fibers can be obtained.
