Definitions
- This invention relates to a face fastener having a high silencing property.
- Japanese Unexamined Patent Publication (Kokai) Nos. 4-224856 and 2-66365 disclose a low noise gear resin prepared by blending polyethylene wax and silicone oil to a polyacetal resin.
- the polyacetal resin has high mechanical strength, it has low toughness, a high specific gravity and a high cost of production.
- Another problem is that when the polyacetal resin is used in an engaged face fastener, it is easily broken from its stem portion.
- a low molecular weight compound such as polyethylene wax or silicone oil is added, a silencing effect can be temporarily obtained, it is true, but the effect does not last for a long time because the compound falls off from the surface.
- Japanese Unexamined Patent Publication (Kokai) No. 5-192939 discloses an engaged face fastener comprising nylon, polypropylene, polyacetal, or the like. Although such an engaged face fastener has various advantages such as easiness of production and a high engagement strength, it is not free from the drawback in that when it is used for the application where vibration is applied to the face fastener, such as fixing members of interior decoration materials of automobiles, it generates offensive noise.
- Nylon for example, has high hygroscopicity and when it absorbs moisture, its mechanical strength drops and causes so-called "shake", so that offensive noise is likely to occur.
- Polypropylene has low heat resistance and low wear resistance and its mechanical strength is likely to drop during use. Accordingly, noise and creak are likely to occur.
- the present invention provides a fastener which has high mechanical strength and high durability, and can be produced easily. Moreover, the fastener of the invention does not generate noise when engaged with a second component and vibration is applied thereto.
- the fastener of the invention comprises a base portion, a stem portion implanted and interconnected to the base portion in a spaced-apart relationship by a predetermined distance from the base portion, and a head portion interconnected to the distal end of the base portion.
- the fastener When the fastener is engaged, the sliding resistance of the fastener is reduced with respect to a relative moving operation of the engaged face fastener.
- the sliding resistance is reduced by using, as at least a part of the stem portion or the head portion, a polyphase polymer material comprising a first polymer resin and a second polymer resin containing at least a fluorocarbon resin or an ultra-high molecular weight polyethylene resin.
- a polyphase polymer material comprising a first polymer resin and a second polymer resin containing at least a fluorocarbon resin or an ultra-high molecular weight polyethylene resin.
- the term "polyphase” that the two polymers form a sea- island like phase-separated structure, and more preferably, the first polymer forms a continuous phase (sea) and the second polymer forms a discontinuous phase (islands).
- the islands preferably have a size of from 0.01 to 100 ⁇ m.
- the islands can remarkably improve the silencing properties without lowering good mechanical properties and chemical properties of the first polymer.
- an excess amount of discontinuous phase for example, an addition of an excess amount of fluorine-containing polymer provides a larger size of discontinuous phases which act like continuous phase, and lowers mechanical properties of the first polymer, and it is not preferable to use an excess amount of discontinuous polymer.
- the present invention provides a fastener having a high silencing property comprising a base portion, a stem portion implanted and interconnected to the base portion in a spaced-apart relationship by a predetermined distance from the base portion, and a head portion interconnected to the distal end of the base portion, wherein the flexural elastic modulus of the fastener is increased so as to reduce a relative moving distance with respect to a relative moving operation of the engaged face fastener.
- a preferred means for improving the flexural elastic modulus is to cause at least a part of the stem portion or the head portion to contain an amorphous polyamide resin as the first polymer resin.
- the present invention also provides an engaged face fastener and a method of producing a fastener.
- the fastener of the invention is typically engaged to another fastener in a face-to-face manner.
- the fastener may be engaged to a wide variety of components such as a hook-type material, a nonwoven fabric, a predrilled metal or plastic plate, etc.
- Fasteners comprising a base portion, a stem portion implanted and interconnected to the base portion in a spaced-apart relationship by a predetermined distance from the base portion, and a head portion interconnected to the distal end of the base portion, and a production method thereof, are disclosed in U.S. Patent Specification Nos. 5,242,646, 4,290,832, 5,077,870 and 4,894,060 for example, and the shape and structure of the fastener and the production method thereof according to the present invention may be the same as those disclosed in these U.S. Patent Specifications and other known references.
- the characterizing feature of the present invention primarily resides in the material composition of the fastener.
- first polymer resin represents the resin which constitutes the fastener and imparts a mechanical strength to the fastener.
- the silencing property can be improved by blending either a fluorocarbon resin or a ultra-high molecular weight polyethylene resin to this first polymer resin.
- the silencing property can be improved by the appropriate selection of the first polymer resin itself.
- the first polymer resin used in the first embodiment of the present invention examples include a polyamide resin, a polypropylene resin, an ionomer resin, a urethane resin and an acrylic resin. Particularly preferred among them are thermoplastic resins such as the polyamide resin and the polypropylene resin because they provide a high mechanical strength, high durability and easy moldability.
- polyamide resin represents those polymers which are synthesized by the chemical reaction between organic acids and amide compounds, and generally denotes crystalline nylons such as 4,6-nylon, 6,6-nylon, 6-nylon, 6,10- nylon, 6,12-nylon, 11-nylon, 12-nylon, aromatic polyamides, etc.
- offensive noise can be suppressed by dispersing and/or blending a phase comprising a second polymer resin with the first polymer resin.
- the second polymer resin comprises either a fluorocarbon polymer or an ultra-high molecular weight (UHMW) polyethylene.
- UHMW ultra-high molecular weight
- Fluorocarbon resins useful as the second polymer resin include a synthetic polymer containing a fluorine atom or atoms in the molecules thereof.
- the fluorocarbon resin include polytetrafluoroethylene (PTFE), fluorinated ethylene-propylene resin (FEP), fluorinated ethylene- perfluoroalkylvinylether copolymer resin (PFA), polychlorotrifluoroethylene (PCTFE), ethylene-tetrafluoroethylene copolymer resin (ETFE), polyvinylidene fluoride resin (PVDF), polyvinyl fluoride resin (PVF), and so forth.
- PTFE polytetrafluoroethylene
- FEP fluorinated ethylene-propylene resin
- PFA fluorinated ethylene- perfluoroalkylvinylether copolymer resin
- PCTFE polychlorotrifluoroethylene
- EFE ethylene-tetrafluoroethylene copolymer resin
- a resin comprising the first polymr r resin and the fluorocarbon resin is commercially available.
- PT F (fluorocarbon resin)-containing polyamide resin is sold by Unitika (K.K.), and this product can be used as the material for the fastener of the present invention.
- the ultra-high molecular weight polyethylene useful as the second polymer resin is a polyethylene having a mean molecular weight of at least 1,000,000, and is commercially available from Mitsui Petrochemical Co., Ltd.
- the second polymer resin preferably has low fluidity.
- the two resins are preferably kneaded and molded in advance into pellet using a biaxial extruder before they are used for injection molding.
- a sufficient permanent silencing effect can be obtained by adding 0.1 to 100 parts by weight of the second polymer resin per 100 parts by weight of the first polymer resin. While more or less of the second polymer resin can be used, it has been found that if the amount of the second polymer resin is less than 0.1 part by weight, the continuous effect of improvement is low, and if it exceeds 100 parts by weight, on the other hand, the strength of the fastener remarkably drops, although the permanent silencing effect can be obtained.
- the fastener is bonded in many cases to a to-be-bonded article such as a coated plate, through an adhesive tape.
- the bonding strength between the back surface of the base portion of the fastener and the adhesive tape is very important, and the bonding strength with the adhesive tape drops when the amount of addition of the second polymer resin exceeds 100 parts by weight.
- the amount of the addition of the second polymer resin is preferably from 50 to 40 parts by weight, and more preferably, from 10 to 25 parts by weight per 100 parts by weight of the first polymer resin.
- offensive noise can be suppressed by increasing the flexural modulus of the fastener. This reduces the distance the fastener can move when it is vibrated. It has been found that an amorphous polyamide resin may be used as the first polymer resin to increase the flexural modulus.
- amorphous polyamide resin means those polyamide resins which are obtained by the chemical reaction between diamine compounds such as hexamethylenediamine and bis(4-amino-cyclohexyl)-methane derivatives and unsaturated carboxylic acids such as isophthalic acid and terephthalic acid, and a polyamide resin Cx2500 of a Unitika K.K. and #330 of DuPont correspond to this resin.
- the amorphous polyamide resin is preferred as the first polymer resin of the fastener of the present invention in order to improve the silencing property.
- a thermoplastic elastomer may be blended with this amorphous polyamide resin. This provides an elastomer phase having high stress absorptive power which is discontinuously dispersed in the amorphous polyamide phase. As a result, brittleness of the amorphous polyamide resin can be improved remarkably, durability of the fastener can be improved and eventually, the silencing effect can be maintained for a long period. From these aspects, the thermoplastic elastomer is preferably blended.
- thermoplastic elastomer useful in the invention has relatively lower fluidity than the amorphous polyamide resin. Therefore, to blend the thermoplastic elastomer to the amorphous polyamide resin, the two materials are preferably kneaded and molded in advance into a pellet form using a biaxial extruder, etc., when they are used in an injection molding machine.
- thermoplastic elastomer having a melt index of 0.1 to 50 at 230°C (in accordance with ASTMD-123B, 2,160 g-load) is preferably used. If the melt index is less than 0.1, a fastener having a very fine structure cannot be produced easily because the resin has low fluidity inside the injection mold. If the melt index exceeds 50, the mean molecular weight becomes relatively so low that high toughness of the amorphous polyamide is impeded. Further, the flexural elastic modulus of the thermoplastic elastomer is suitably from 100 to 20,000 kgfi'cm 2 .
- the flexural elastic modulus is less than 100 kgfi'cm 2 , the mean molecular weight is relatively so low that the heat-resistance of the polyphase thermoplastic composition drops. If the flexural elastic modulus is greater than 20,000 kgf /cm 2 , on the other hand, the elastic effect of the elastomer phase becomes low.
- thermoplastic elastomer described above may be modified by an acid anhydride or a functional group such as an epoxy group, a chlorine group, a carboxyl group, etc., or has an ester structure, an ether structure or a urethane bond or an amino bond.
- the elastomer phase can absorb the external stress which is applied at the time of sliding, by reinforcing the interface between the polyamide phase and the elastomer phase.
- Olefin type elastomers such as;
- Polyester type elastomers such as; 1. vinyl chloride
- Styrene type elastomers such as;
- SEBS styrene/ethylene/butylene/styrene block copolymer
- SEBS carboxyl-modified copolymer
- Fluoro-type elastomers such as; 1. vinylidene fluoride type elastomers
- modified thermoplastic elastomers include maleic anhydride-modified ethylene/propylene elastomer T-7712SP manufactured by Nippon Gosei Gomu K.K., ethylene/glycidyl methacrylate copolymer "Bond Fast 20B” manufactured by Sumitomo Kagaku K.K. and carboxyl-modified SEBS copolymer "Toughtec Ml 943" manufactured by Asahi Kasei K.K.
- the thermoplastic elastomer can be added in an amount within the range of 1 to 150 parts by weight per 100 parts by weight of the first polymer resin.
- the amount of the elastomer exceeds 150 parts by weight, the elastomer phase dispersed in the continuous phase of the amorphous polyamide resin becomes continuous, so that the creak sound at the time of sliding cannot be prevented. If the amount is less than 1 part by weight, the effect of improvement is low. Further, a preferred range of the amount of addition of the thermoplastic elastomer is from 10 to 70 parts by weight.
- a mixture of a crystalline polyamide resin and the amorphous polyamide resin can be used so as to improve toughness and compatibility of the amorphous polyamide to the thermoplastic elastomer and to reduce the cost, and in the aspect of good balance of flexibility.
- the mixing ratio of the crystalline polyamide resin and the amorphous polyamide resin is preferably such that the crystalline polyamide resin accounts for 1 to 150 parts by weight on the basis of 100 parts by weight of the amorphous polyamide resin.
- the crystalline polyamide resin has higher compatibility than the amorphous polyamide resin, and is free from the drop of mechanical properties.
- the amount of the crystalline polyamide exceeds 150 parts by weight, the flexural elastic modulus will be remarkably reduced due to the increase of water absorbing power as one of the properties of the crystalline polyamide resin added to the amorphous polyamide resin. This makes it difficult to maintain a high flexural elastic modulus which is essentially necessary for preventing the creak sound at the time of sliding.
- the amount of the crystalline polyamide resin is preferably 5 to 100 parts by weight per 100 parts by weight of the amorphous polyamide resin and most preferably, from 10 to 90 parts by weight.
- the crystalline polyamide resin to be used in the present invention are 4,6-nylon, 6,6-nylon, 6-nylon, 6, 11 -nylon, 6,12-nylon, and copolymer nylon (e.g. 6/66 copolymer nylon, 6/12 copolymer nylon).
- a more definite example is a 12-nylon under the trade name "30140" of Ube Industries.
- coloring agents are especially useful in detecting the presence of the core of the system remaining after a destructive disengagement of the fastener.
- coloring agents useful in the invention include inorganic pigments, organic pigments, and particularly red coloring agents such as red oxide, cadmium red, etc.; yellow coloring agents such as barium yellow, strontium yellow, etc.; blue coloring agents such as ultramarine blue, cobalt blue, phthalocyanine blue, etc.; green coloring agents such as chromium oxide, cobalt green, phthalocyanine green, etc.; and black coloring agent such as carbon black, graphite, etc.
- a preferred fastener is black. This facilitates visual detection of the core for the stem after destructive disengagement because the remainder is white, particularly when the remainder comprises a polyphase of crystalline polyamide and amorphous polyamide resins. .
- the fastener was made black by the use of carbon black
- the following advantages were observed: a. A small amount of black carbon provides a remarkable black- coloring effect.
- the carbon black increases elastic modulus of a fastener, improves the silencing property, and makes control of mechanical strength easy. In addition, even in the case where silicon resin or ultra high molecular weight polyethylene resin is added to reduce a sliding resistance, a predetermined elastic modulus of the fastener is maintained and there is no fear of decreasing handwearing properties and mechanical strength.
- c. When the present article is molded, a certain amount of waste resin material is provided. To reduce a cost, such waste is mixed by stirring with fresh resin material to reuse. In this case the carbon black smoothes the mixing.
- carbon black thermal black, acetylene black, channel black, furnace black, etc.
- carbon black thermal black, acetylene black, channel black, furnace black, etc.
- Asahi Thermal manufactured by Asahi Carbon; Carbon Black #2400B, #1000, MA8, #40, etc., manufactured by Mitsubishi Chemical, and the like can be used.
- the shape of the carbon black may be globule or fiber, though chain shape comprising a plurality of particles linked each other is also preferable because it provides electric conductivity increasing effect.
- Primary average particle size of these carbon blacks are preferably 10 to 150 run. Where the size is smaller than 10 nm, mixing and dispersion is not difficult, while the particle size is larger than 150 nm, coloring power is remarkably decreased. Accordingly, coloring power of carbon black suitable for the present invention is at least 50%, and more preferably at least 100%. It is because black- coloring is possible by a smaller amount of carbon black.
- the primary average particle size is measured by electromicrocopy, and coloring power is measured according to JIS K6221.
- coloring agent of the present invention graphite-coated carbon black is most preferable. A small amount of addition provides coloring effect, and an adequate level of lubrication effect. Examples of these coloring agents are products of tradenames #4010, #4040, manufactured by Mitsubishi Chemical: a product of tradename spheron 6, stering R, manufactured by CABOT; and the like.
- an amount of a coloring agent added in the present invention is 0.1 to 100 parts by weight relative to 100 parts by weight of high molecular weight resin material.
- An addition of less than 0.1 parts by weight provides a poor black- coloring effect, while an amount of more than 100 parts by weight makes dispersion and mixing difficult, necessitates the use of high temperature of a molding operation and a mold, and surface lubrication is lost.
- a range of more preferable amount of a coloring agent is 0.5 to
- ingredients may also be used in the present invention. They include paraffin wax and higher fatty acids such as palmitic acid, stearic acid, oleic acid, etc. Additionally, a small amount of calcium stearate, fatty acid esters, mineral oil, silicone oil, or the like, may also be added to the resin composition used to make the fastener. These additive components provide an auxiliary silencing effect. The amount of these additives used is 0.01 to 5 parts by weight and more preferably, 0.1 to 3 parts by weight, per 100 parts by weight of the resin. If the amount is outside the range of O.Ol to 5 parts by weight, the auxiliary improvement effect is low, or tape bondability will drop.
- the above-mentioned resin composition is also preferably used for modifying fastener, for example those having so-called clips, hooks or bosses under the base portion to facilitate attachment of the fastener to a substrate.
- the above-mentioned resin compositions are preferable for, not only fastener, but also clip, hook or boss not having fastener, because sliding resistance reduced.
- the fastener can be produced by the following method.
- the method includes the following steps: a. the step of so arranging two sheets for the base portion as to face each other with a predetermined gap, and feeding them in the same direction; b. the step of alternately implanting mono-filaments by a striker to the sheets heated and molten; c. the step of cutting the monofilaments at an intermediate portion of the predete ⁇ nined gap of the sheets; and d. the step of heating and melting a part of the monofilaments and shaping the head portion.
- the advantage of this method is that a wound article of a fastener is available, and the product can be economically produced with high production efficiency.
- the method comprises the following steps. a. the step of rotating in an axial direction a mold having therein a cavity having a hole for inserting a molten resin, the hole corresponding to the stem portion of the engaged face fastener; b. the step of sucking air in an inside direction of the mold; c. the step of carrying out injection molding of the molten resin to the surface of the mold; and d. the step of peeling a molded resin from the mold and heating it to mold the head portion.
- the method comprises the following steps: a. the step of extruding a molten resin by a resin extruder and molding a rail-like article comprising the base portion, and the stem portion and the head portion spaced apart by a predetermined gap in only a direction extending straight to the extruding direction; b. the step of forming cut-in portions in the rail-like article in a direction at about 90°with respect to the extruding direction with predetermined gaps between them; and c. the step of heating and stretching the base portion, and separating the stem portions of the fasteners adjacent to one another, in the extruding direction.
- This method has the advantage that a fastener having a higher strength can be economically produced.
- Two fasteners were bonded to separate stainless steel sheets through a primer C-100 and an acrylic foam tape #4215 manufactured by Sumitomo 3M Co., Ltd., respectively, and were then engaged with each other in a cross direction.
- the other was vibrated at an amplitude of 0.5 mm or 1.0 mm and a frequency of 12 Hz using a vibrator (a micro-shaker MEE-035 manufactured by Akashi K.K.) equipped with a displacement meter (a laser displacement meter LD-2500 manufactured by Keyence Co., Ltd.) so as to measure the occurrence of noise.
- the evaluation OK represents the case where no offensive noise occurred, and NG does the case where it occurred.
- the water absorption test was carried out in accordance with ASTM D570, by immersing each testpiece in water at 23°C for 24 hours.
