Method of making sound insulation with high loft |
摘要 |
Sound insulation core material is made by melt-blowing a polypropylene resin having a hydroxystearamide wax additive to produce a fibrous mass having improved loft. The core material is encased between outer layers of spun-bond polyethylene fibers by longitudinal seams and transverse seams to form a product suitable for use in dishwashers.
