How to detect chemical fibers?

Release time:


The full name of chemical fiber is chemical fiber, which refers to fibers made from natural or artificially synthesized polymer materials. According to the different sources of raw materials, it can be divided into artificial fibers with natural polymer materials as raw materials and Synthetic fiber with synthetic polymer materials as raw materials.

The preparation of chemical fibers usually involves spinning natural or synthetic polymer or inorganic materials into a melt or solution, which is filtered, metered, and extruded into a liquid stream by a spinneret (plate), and then solidified into fibers. Nowadays, fibers, known as raw fibers, have poor mechanical properties and require a series of post-processing processes that meet the requirements of textile processing and usage. Post treatment mainly focuses on the stretching and heat setting of fibers to improve their mechanical properties and dimensional stability. Stretching is the process of orienting large molecules or structural units in primary fibers along the fiber axis. Heat setting mainly involves relaxing the internal stress in the fibers.

The post-processing of wet spun fibers also includes processes such as washing, oiling, and drying. When spinning, it can be wound into a tube according to the above steps; When spinning short fibers, additional processes such as curling, cutting, and packaging are required. The main business scope includes food, agricultural products, environmental soil, environmental protection and industry standard training, retail services, etc., providing you with convenient testing services. If you have any needs, you can contact us.

The testing items include

Component analysis: identification of chemical fiber components, chemical composition of chemical fibers, quantitative chemical analysis, qualitative chemical analysis, etc.
