| titleOfInvention | Low release melamine formaldehyde nonwoven and nonwoven materials |
| abstract | The present invention relates to melamine-formaldehyde based nonwoven or nonwoven materials, and to a process for their preparation. A melamine formaldehyde resin is used which has a low formaldehyde content, preferably an M: F ratio of 1: 2 and the methylol group is almost completely etherified with methanol. And spun into a mass flow melt at 0.3 to 3.0 g / min per nozzle at a temperature of 80 to 200 占 폚. The gas stream is flowed at a temperature of 130 to 330 캜 in the mass flow melt. The formed fibers and / or flakes are stacked to form a nonwoven material, treated with gaseous HCl, and heat treated to allow air to flow over or through the nonwoven material, thereby increasing heat transfer. Stepwise raising the temperature to 340 < 0 >C; The temperature is raised to a maximum of 20 DEG C / min in the range of 80 DEG C to 160 DEG C and then to a maximum of 100 DEG C / min. The material is then maintained for 5 to 90 minutes at a pre-reached temperature of 340 DEG C or less while partially replacing the convection air with fresh air. It is then rapidly cooled to 30 to 60 ° C. Nonwoven or nonwoven materials are suitable as heat dissipating material or soundproofing material. |
