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.

Introduction In many applications of ferromagnetic materials both the magnetic properties and also the mechanical properties of these materials are important.
The majority of magnetic materials, such as ferromagnetic metals, and alloys of metals and ceramic materials, show small susceptibility to deformation, and are also frequently brittle [1] .

Geopolymer materials as an innovation in green concrete technology were introduced as a good solution to reduce cement use at construction industry.
In order to find another raw material for manufacturing geopolymer concrete, many researches start to develop alternatives eco green raw materials besides fly ash such as volcanic ash.[6] One things that needs to be consider in order to find alternative substitute raw material for geopolymer concrete is the similarity chemical content [7].
In addition, the result of this study was expected to give good recommendation about optimum VA content in geopolymer concrete fly ash based and to give an alternative green raw material for geopolymer concrete beside fly ash Materials Fly ash type F obtained from Paiton Power Plant while volcanic ash gathered from Kelud Mountain Kediri was used as based materials.

Introduction In recent years, the use of titanium (Ti) and Ti alloys as implant materials has been increased in comparison with many other metals.
To improve the healing properties, coating cp-Ti materials with HA is a common technique.
Moreover, it has been reported that the materials prepared by sol-gel deposition are more bioactive than those prepared by other methods [14].
