| titleOfInvention | A kind of medical fiber hot-melt coating resin and preparation method thereof |
| abstract | The invention provides a medical fiber hot-melt coating resin and a preparation method thereof. The coating resin achieves a stable low-melting hot-melt zone for slices by introducing a combination of sebacic acid, isophthalic acid, PBT and 2,2-dimethyl-1,3-propanediol during synthesis, which is used for The production of low-temperature hot-melt fibers has laid the foundation; at the same time, the use of this product for modification has higher firmness in the co-extrusion process with PET materials in sheath-core spinning; by introducing PA6 copolymerization in the pre-condensation process, subsequent compounding has been realized. The thermal bonding of spinning and PA achieves the barrier effect of using PA and reduces the use requirements; through a suitable vacuum crystallization and viscosity-increasing process, the water content of the slice can be effectively controlled, and at the same time, it can ensure high vacuum and temperature stability. , the intrinsic viscosity is greater than 0.95dl/g, which fully meets the requirements of composite spinning and can effectively improve the yield of downstream sheath-core spinning. The raw materials used in the hot-melt coating resin are cheap and easy to obtain, the preparation process is relatively simple, and it has great industrial application value. |
