The afforestation techniques in this experiment were included using no-woven-cloth container seedling with balance-root-system,rational arrangement of tree-shrub-rattan,scale-shaped pit soil preparation,level step soil preparation,terraced field,shrub and grass cove.

The modern forest seedling culture idea,the development trends of nursery container and the core of balanced root system light media seedling cultivation techniques are introduced.

Study on Behavior of Some Kinds of Special PP Compound for Non-woven Fabric;

Discussion on production process of ES fiber for non-woven fabrics;

Grafting modification of polypropylene non-woven fabric;

The performance of synthetic domestic wastewater treatment was evaluated in the nonwovens-member bioreactor with different pore diameter(3 μm and 5 μm) nonwovens as filtration material in the same reaction condition.

In 1993, the production output of nonwovens is expected to be about50 kt in Guangdong, amounting to a half of the total output in China.

In this paper,the technology of making PU/Nonwovens laminated sheet using PP as base material for the car and mincar interior ceiling decoration was introduced.
