| Abstract: | To realize the on-line production of melt blown-dry laid composite automobile sound-absorbing material,the 300 g/m2 nonwoven is developed and the processes of melt blown fiber,dry-laid web and lamination of melt blown dry-laid web are investigated.The result indicates that the perfect composite sound-absorbing material can be obtained with following conditions: polypropylene chip with melt index 150 g/min,controlled die temperature,regulated hot air pressure and collection distance for melt blowing,the dry-laid web using 3.3 dtex three dimensional crimp PET hollow staple fiber and flame retardant PET staple fiber for dry-laid web,the jet angle of melt blown fiber with the web is 75~83°. |
| Keywords: | melt blowing fiber web melt flow index on-line lamination sound-absorbing material |
