摘要:
A non-woven fabric composite containing coir fibers and a method for producing such composites. The non-woven fabric composite is comprised of coir fibers, which are large diameter, lignin-rich fibers, with a high viscous flow temperature and a high degradation temperature combined with fibers made of a thermoplastic polymer with a lower viscous flow temperature such as polypropylene (“PP”), polyethylene (“PE”), polylactic acid (“PLA”), and polyester (“PET”) or mixtures thereof. A hot-pressed non-woven fabric composite material prepared from the non-woven fabric composite.

摘要:
A lawn-aerating machine has a chassis which may be moved about the lawn on wheels. A transmission case moves vertically relative to the chassis and from the case depend drills shaped to dig holes in the lawn. A prime mover drives each of the drills. Means is provided to lower the drills relative to the chassis under control of the operator.
摘要:
A non-woven fabric composite containing natural fibers and a method for producing such composites. The non-woven fabric composite is comprised of large diameter, lignin-rich natural fibers with a high viscous flow temperature and a high degradation temperature combined with fibers made of a thermoplastic polymer with a lower viscous flow temperature such as polypropylene, polyethylene or a biodegradable thermoplastic polymer fiber such as polylactic acid, or mixture thereof. A hot-pressed non-woven fabric composite material prepared from the non-woven fabric composite.
