Abstract
A fishing line includes a core portion composed of multiple Polyethylene wires and a coating is mounted to the core portion and combines the Polyethylene wires together. The coating is a mixture of Polyethylene having low fusing point, silicon resin and powder of hexamethylenebis-3-(3,5-ditertiarybutyl-4-hydroxyphenyl) propionamide. The Polyethylene is melted and the mixture is extruded to combine the Polyethylene wires. The coating is then cooled to solidify.
Description




FIELD OF THE INVENTION




The present invention relates to a fishing line and a method for making the fishing line which is composed of multiple Polyethylene wires and coated by a mixture of Polyethylene, silicon resin and hexamethylenebis-3-(3,5-ditertiarybutyl-4-hydroxyphenyl) propionamide.




BACKGROUND OF THE INVENTION




A conventional fishing line is required to have several features such as durable for friction, flexibility and light in weight. It is difficult to find a fishing line having all the important characters mentioned above.




The present invention intends to provide a fishing line that reaches the above goals and a method for making the fishing line.




SUMMARY OF THE INVENTION




In accordance with one aspect of the present invention, there is provided a fishing line which comprises a core portion which is composed of multiple Polyethylene wires and a coating on an outside of the core portion. The coating is a mixture of Polyethylene having low fusing point, silicon resin and powder of hexamethylenebis-3-(3,5-ditertiarybutyl-4-hydroxyphenyl) propionamide.




The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.











BRIEF DESCRIPTION OF THE DRAWINGS





FIG. 1

is a perspective view to show the fishing line of the present invention;





FIG. 2

shows the how the fishing line is made; and





FIG. 3

shows the manufacturing processes of the method for making the fishing line.











DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT




Referring to

FIGS. 1 and 2

, the fishing line “A” of the present invention comprises a core portion which is composed of multiple Polyethylene wires and a coating


100


wraps around the core, portion. The coating


100


is a mixture


11


of Polyethylene having low fusing point, silicon resin and powder of hexamethylenebis-3-(3,5-ditertiarybutyl-4-hydroxyphenyl) propionamide. The fusion point of the Polyethylene is 130 to 150 degrees Celsius and the mixture


11


includes 95% to 99% of Polyethylene with low fusion point, 1% to 5% of silicone resin and 0.1% to 0.3% of an agent comprising hexamethylenebis-3-(3,5-ditertiarybutyl-4-hydroxyphenyl) propionamide. The Polyethylene with low fusing point is melted and pressurized to combine the Polyethylene fishing lines by an extruder


20


. The coating


100


is then cooled into clod water and solidified so as to have a better durable feature and water-proof feature.





FIGS. 2 and 3

shows the steps of the method for making the fishing line “A” and includes the following steps:




step (1): releasing multiple Polyethylene wires


12


from mandrels


51


,


52


and the Polyethylene wires


12


being arranged into a core portion


10


, the core portion


10


being coated with a coating


100


which is composed of a mixture


11


having low fusion point, the mixture being melted and extruded by an extruder


20


at the pressure of the extruder is 20 to 30 kg/cm


3


to combine the Polyethylene wires


12


;




step (2): the core portion


10


together with the coating


100


passing a cooling device


54


to solidify the coating


100


, the cooling device


54


including water having temperature between 5 to 10 degrees Celsius; and




step (3): receiving the cooled fishing line of step (2) to a mandrel (


55


).




The Polyethylene wires


12


can be collected by way of weaving or twisting to form the core portion


10


. The coating


100


is durable, flexible and has higher friction efficiency.
