Abstract: The PP/PE composite fibers were prepared by melt extrusion, using polypropylene (PP) and polyethylene (PE) as raw materials and ethylene-˚Ctene bl˚Ck copolymers (OBC), titanium dioxide, antioxidants as additives. 3D stereoscopic embossed polyolefin nonwovens with "cross" pits and "O" type relief structure applied to topsheet of diapers were produced through air bonding pr˚Cess and 3D stereoscopic pressure rollers, respectively.
The PP/PE composite fiber prepared by melt extrusion, using polypropylene (PP) and polyethylene (PE) as raw materials and ethylene-˚Ctene bl˚Ck copolymers (OBC), titanium dioxide, antioxidants as additives were investigated in this paper. 3D stereoscopic embossed polyolefin nonwovens with "cross" pits and "O" type relief structure applied to topsheet of diapers were produced through air bonding pr˚Cess and 3D stereoscopic pressure rollers, respectively.
Experimental Materials.
The PP/PE composite fiber was prepared by using polypropylene (PP, 60 Phr) and polyethylene (PE, 30 Phr) as raw materials and using ethylene-˚Ctene bl˚Ck copolymers (OBC, 8Phr), titanium dioxide (1.5 Phr), antioxidants (0.5 Phr) as additives by melt extrusion at 160~190 ˚C. 3D stereoscopic embossed polyolefin nonwovens comprising PP/PE fiber composites were made ​​by the air bonding pr˚Cess at 150~160 ˚C for 18 sec., and at flower roll temperature of 130 ~ 135 ˚C and at light roll temperature of 125 ~ 130 ˚C pressed into "cross" pits and "O" type relief structure of 3D stereoscopic were applied to topsheet of diapers.

The 3rd Party Reverse Logistic System (3PRLS) was then introduced to improve the efficiency of materials recycling rate in the operation of EIP.

It is hard to generate inner complex-shaped parts because the support materials are difficult to remove from the inner structure.
Method and Materials Many materials may be used in RP processes, such as polymer, metal, and ceramic.
If without support materials under the overhanging, the first layer of overhang will yield a downward deflection.

Melting point depression of materials has many applications such as to checking the purity of the materials [1] establishing the phase relations and thermal stability in nano particles which are different from the bulk materials among.
Various methods are employed to examine melting temperature of distinct materials.
Similar melting temperature decline occurs in lead materials with octahedral shapes, which drop from 600 K to 573 K in bulk.
