Description

The line that is used for aspects such as racket, stringed musical instrument and fishing gear

At present, use various synthetic lines (for example polyamide and dacron line) to use usually, to replace the natural material (the intestines muscle of for example from the cetacean animal, obtaining) that those use for a long time always as the line of aspects such as racket such as tennis and stringed musical instrument.Equally, also replace the natural material that those make setline and fishnet with various synthon.

The line that synthetic line is made compared with those natural materials has many advantages, and material source abundance, line be with low cost, be easy to make and generally high intensity can be arranged.But their resistance to abrasion, photostability aspect still need be improved, and can not make us satisfied fully simultaneously aspect permanance.

When considering the problems referred to above, for example doing under the tennis racket line situation, notice that line is disconnected easily owing to rub between main line part (being called main line) and the horizontal line part (being called horizontal line).Line is disconnected owing to following two aspect reasons:

(1). when whipping racket, at first be line to be strained along its length direction with line, and then along laterally tension.When corresponding position installed horizontal line, with certain position very fast firmly tension of the following horizontal line of rubbing contact situation mutually of every main line, the result just formed the U-shaped indenture on main line.Under serious situation, make the extent of damage of main line approach half of its diameter probably.If use racket in this state, then in the short time, under the collision of ball, will make main line disconnected.

(2). square stance, transverse movement racket often, and make the ball rotation.When brandishing bat in this way, ball causes the main line of some and horizontal line rubbing contact to move easily at every turn, and the result causes the scar development on the certain position of main line, makes the line at this position disconnected.

For fear of the problems referred to above occurring, people get used to the material that is coated with silicone oil, paraffin wax or lubricant class on the line, or before making with lubricator, resin solution or molten resin are applied on line.

During the match ball, when the racket square stance, ball makes line suffer the big friction force of moment, so that produces the very high heat of friction of temperature, and the result causes line surface local ground to dissolve.Equally, each batting, ball also can carry gathers in threshed grain on a threshing ground sand, grit on the ground and adheres to the online part that is melted, thereby the friction force of this part is strengthened, and causes the wearing and tearing aggravation.In addition, each square stance, ball be the go offline lubricant on surface of erasing also, causes the further wearing and tearing of line.

The permanance of improving line depends on that the wear resistance that how to improve the line surface is to prevent wearing and tearing.In order to reduce the wearing and tearing on line surface, the resin coated of preferably using high-melting-point, high smooth degree, does not still have a kind of resin that had both had high-melting-point and the polyamide that is widely used as wire material had been shown good adhesion on line, therefore, it is very big improving line abrasion-resistant surface difficulty.

The another kind of way that proposes as the resistance to abrasion of improving line is that a kind of metal powder is sneaked into the line top layer, but owing to can not mix metal powder equably, so will have uniform resistance to abrasion also very difficult to whole line top layer.Moreover this suggestion also exists with the wearing and tearing development, and the metallic particles of exposing surface can aggravate wear problems.

Problem discussed above is not limited only to tennis, shuttlecock and the similar line that uses of aspects such as racket, and all runs into same problem at the stringed musical instrument string of a musical instrument that bears friction with being subject to rub, be subjected to illumination to do the aspects such as fishing gear line that setline or fishing net use.So the strong expectation of people can address these problems technically.

With the improving one's methods of line, it has overcome above-mentioned problem about aspects such as racket, stringed musical instrument, fishing gears in the present invention.

Fundamental purpose of the present invention provides a kind of line that uses at aspects such as racket, stringed musical instrument and fishing gears.This line comprises a main body made from synthon and the surface that one deck high-wearing feature is arranged.

Another object of the present invention provides line a kind of above-mentioned this type, that have higher fast light, water-fast, moisture-proof, high-wearing feature, the serviceable life of extended line greatly in addition.

The line of the present invention that is used in aspects such as racket, stringed musical instrument, fishing gear comprises a main body made from synthon and at least in the layer of metal film of its surface coverage.

The main body of line of the present invention comprises an independent monofilament, or strand multiply monofilament together, perhaps Duo multifilament.

According to another embodiment of the invention, the line main body comprises the core formed with independent monofilament and twines one deck at least around core, and the many monofilament that bond together with bonding agent and core.

Multiple metal film on the line main body is only in body surfaces, or at wicking surface with twine on the surface of monofilament of heart yearn and form.

Line main body of the present invention is to make with a kind of composite fibre materials of selecting in the fiber material of polyester, polyamide, fluorocarbon, aromatic poly amide and polyolein fiber that comprises at least.

According to the present invention, metal film is at least with a kind of the making in the metals such as aluminium, chromium, copper, nickel, titanium, silver, gold, zinc, or with making after these metal mixed.

Thereby the line of making according to the present invention has following advantage:

(1) the line surface is to make with metal, has replaced the synthon of common employing or the film of synthetic resin.So just make line have high-melting-point, and obviously improved wear-resistant, the water-fast and moisture-resistance of line.

During (2) with the common line of a kind of resin molding coated of protectiveness, its thickness is about 20～30 microns, is 1/10～1/1000 of this thickness and can be as thin as with metal film.Thereby according to recent needs line of the present invention can do carefullyyer, tightr and lighter and handier.

(3) metal film makes main body fully isolated with light such as daylight, fluorescence, has prevented that ultraviolet irradiation from causing that the line main body goes bad, thereby has guaranteed sunproof improvement.

(4) hard metal film can prevention can cause the little slight crack expansion of rupturing.

(5) thickness of metal film can be extremely thin, thereby can make profile, surface structure and the feel of line the same with line main body under the film.

(6) metal film can be extremely thin, so kept enough pliabilities.By changing thickness, be easy to the hardness and the rigidity of control line.

(7) line of the present invention has replaced gutstring, and is applicable to tennis, shuttlecock and similar racket, and be widely used as the stringed musical instrument that must be wear-resisting, anti-sunlight string, setline, line or the like weaves a fish net.

Fig. 2 is an enlarged drawing along II among Fig. 1-II section that line is got;

Fig. 3 to Fig. 8 is the profile of other different embodiment of expression.

What Fig. 9 represented is a skeleton view of measuring the abrasion resistance device.

Fig. 1 and Fig. 2 represent the most typical line of those enforcement the present invention, and the line that uses at aspects such as racket, stringed musical instrument, fishing gears.With reference to this figure, nylon monofilament of line main body 1 usefulness is made.Nickel metal film 2 is covered in line main body 1, and its thin and thick reaches 1000 dusts, has made line S.

With forming metal film 2 on the vacuum evaporation method of metal or the online main body 1 of chemical plating method.To discuss these methods below.

The metal vacuum method of evaporating: dry in a vacuum line main body 1 earlier in case of necessity, put in the vacuum evaporation apparatus then.In the preliminary work of handling, the line main body is entangled on the feeding spool with up-coiler.When the evaporating area, preferably gently turn line main body so that the metal that will plate equably spraying plating on main body.For example can come the rotational line main body like this, promptly be wrapped in the line main body on the spool before, rotate reels with 5 to 10T/M, make the twisting of line main body, and then it be wrapped on the spool.When the line main body by evaporating area when wireline reel moves, the line main body is wanted untwisting and backward rotation.The evaporation process process is about 2 * 10 ^-4Carry out under the vacuum degree condition of mm Hg.Evaporate used metal and except that nickel, also have aluminium, chromium, copper, titanium, silver, gold, zinc and suchlike metal.These metals use separately or their at least two kinds of mixing are used.In these metals, aluminium, copper and suchlike metal have high-termal conductivity, thereby are advantageous with regard to its thermotolerance and charging property.For example for racket, use during the racket, this metalloid will can not accumulate heat of friction.Sprayed metal film 2, its thickness is generally 1000 dusts, but as required, also can be the 100 Izod right sides.The superiority of vacuum evaporation method is that resulting main body will can not absorb moisture content again after forming metal film 2 on the line main body 1 that is in drying regime, and moisture content can cause that line strength descends.Particularly when making main body with polyamide material, this is a big advantage especially.

Chemical plating method

This method be used for limiting viscosity be 0.8 and have 90 the end carboxyls the made line main bodys 1 of monofilament polyester.Make this monofilament degreasing, reinforcement, activation earlier, and then it is electroplated with for example nickel, chromium, copper, cobalt or suchlike metal.Can provide the metal film 2 thicker than vacuum evaporation method with this disposal route, for example thickness is (10000 dust) about 1 micron.Also can form several microns thickness.

When will be to the metal film that obtains with vacuum vapor deposition method or electroless plating method painted, the available resin solution coated metal film that contains coloring agent.And, available light lubrication prescription or resistance to abrasion and the surface flatness of lubricant coated metal film to improve line.
