Preferably, foregoing common monofilament I, common monofilament II are formed using high tensile steel wire drawing, wherein deformation monofilament is The helical corrugation shape processing of spring-like is carried out on the basis of common monofilament II, has larger because deformation monofilament is internal in itself Gap so that sizing material can be penetrated into preferably in all-steel cord, while causes all-steel cord to have more toughness.
Preferably, foregoing high tensile steel wire is the brass plating steel wire that carbon content is 0.80-0.92%, ensures the steel of production Silk cord rigidity is higher, and all-steel cord has higher modulus of elasticity.
Preferably, foregoing cored wire twists with the fingers mode using S and compiles sth. made by twisting.
Preferably, foregoing outer layer upper thread twists with the fingers mode using Z and compiles sth. made by twisting.
Preferably, the lay pitch of foregoing cored wire is 10mm, and the lay pitch of outer layer upper thread is 18mm.
Preferably, foregoing common the monofilament a diameter of 0.20mm of I, Aforesaid deformation monofilament and common monofilament II are a diameter of 0.38mm。
It is of the present utility model to be beneficial in that:The utility model is added in outer layer surface cable architecture by common monofilament basis On the deformation monofilament that is process can effectively improve sizing material filling gap in outer layer upper thread, improve covering for sizing material in all-steel cord Glue rate, it is avoided that in impaired moisture or air that other pernicious gases can invade cored wire, improve Life of Tyre.
