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.
