NONWOVEN FABRIC HAVING IMPROVED AIR PERMEABILITY AND MANUFACTURING METHOD THEREOF |
| 摘要 |
A nonwoven fabric having improved air permeability and manufacturing method thereof are presented. The nonwoven fabric has improved air permeability and is formed with long fiber nonwoven fabric of single or multi layer, wherein the long fiber nonwoven fabric is produced by spinning polytrimethylene terephthalate having viscosity of 0.8 to 1.2 and polyethylene terephthalate having viscosity of 0.6 to 0.8 to sheath/core shape with using each spinneret pack which can spin filaments having different denier from each other and arranged in parallel with each other, and then heat pressing with free-embossing or embossing pattern to bind the filaments.;The nonwoven fabric has excellent air permeability, softness and resistance, which are required for nonwoven fabric sheets used for various purposes as well as their economical production. |

1. The nonwoven fabric having improved air permeability which is formed with long fiber nonwoven fabric of single or multi layer, wherein the long fiber nonwoven fabric is produced by spinning polytrimethylene terephthalate having viscosity of 0.8 to 1.2 and polyethylene terephthalate having viscosity of 0.6 to 0.8 to sheath/core shape with using each spinneret pack which can spin filaments having different denier each other and is arranged in parallel with each other, and then heat pressing with free-embossing or embossing pattern to bind the filaments. |
