Beschreibung
Zusammenfassung:	A core-sheath type resin composition for a conjugate spinning fiber is provided to maintain the superior spinning performance and to have the superior strength. Core ingredients consist of polyethylene terephthalate. Sheath ingredients consist of high density polyethylene resin of 95 weight % and modified polyethylene resin of 5 weight %. The modified polyethylene resin is manufactured by adding the anhydrous compound to the polyethylene resin and extruded by an extruder with a diameter of 40 mm at 190-220 degrees in centigrade, so that a compound with a pellet shape is obtained. The weight ratio of the sheath layer and core layer is 60:40 and the thickness of the fiber is 3 denier.
