The difference between lyocell and copper ammonia, both of which are regenerated cellulose fibers. But the production process is different. The molecular structure of these two fabrics is similar to that of cotton. How do you distinguish these two similar fabrics? Let's analyze the details of Xiaobian in detail.
First of all, in terms of material, lyocell fiber is a regenerated cellulose fiber prepared by using a regenerated softwood fiber as a raw material to prepare a cellulose pulp and then dissolving it in an organic solvent. The solvent used in the production process can be nearly 100% recycled, and it is not easy to pollute the environment. It is a typical green fiber. The copper ammonia yarn dissolves the cellulose raw material, and a series of dissolution processes such as filtration and defoaming can be used to prepare the copper ammonia fiber. Named after treatment with ammonia and copper hydroxide in the manufacturing process, it is a regenerated cellulose fiber named after a solvent.
Secondly, in terms of characteristics, lyocell fiber is soft, breathable, smooth and cool, durable and durable. Its product has good performance and is widely used in high-grade woven or knitted fabrics. Copper-ammonia fiber has the characteristics of refreshing, anti-static, breathing, and drapability, which can avoid discomfort such as stuffiness and is very suitable for use as a high-grade lining material.
The combustion method, microscopic observation method, dissolution method, infrared spectroscopy, etc. specified in FZ/T 01057 cannot completely distinguish the two. According to reports in the literature, the two methods can be comprehensively analyzed and identified by various methods such as dyeing test, copper ion concentration, fibrillation performance, near-infrared spectroscopy and X-ray diffraction analysis. At present, GTT has found that lyocell and cuprammonium fibers can be effectively identified by polarized light microscopy and chemical dissolution of some reagents.
