Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a holding member for a sliding member, and more specifically, a flocked portion having a fiber containing a mixed resin composed of high-density polyethylene and an amorphous thermoplastic resin as a main component. A retainer for a moving member. The retainer for the sliding member is applied to, for example, a window glass of an automobile.

[0002]

2. Description of the Related Art Techniques such as rubbing the surface of a sliding member having flocked fibers by sliding it against a relatively sliding member and rubbing the member have been used in various fields. It's being used. In the field of OA equipment, for example, a cleaning brush that performs cleaning by slidingly contacting a photosensitive drum of a copying machine, a transfer or conveyance belt, a roller, or the like can be given as an example of a retainer for these sliding members. Further, when used as a material for suppressing the window glass of an automobile, the function of preventing the intrusion of water and dust from the outside and the vibration of the glass during traveling, opening and closing, etc. Required for ingredients. The pressing member for the sliding member is required not to damage the sliding contact surface and to have a high degree of durability no matter what purpose it is used in.

Here, weather strips, belt moldings, waist moldings, etc. (hereinafter referred to as "moulds") are used to prevent intrusion of water and dust from the outside. The molding is used as a member having a sealing function at an opening (also referred to as a lip) of a door body having a window glass, and is configured by, for example, a rubber member having a flocked portion.

On the other hand, a means for preventing the vibration of the window glass is called a window glass stabilizer, which means that the pressing member of the sliding member having the hairs implanted locally presses the window glass surface into the door body, This is a method of sliding contact. Since it is sufficient to locally press the surface of the window glass to prevent vibration, a member in which bristles are planted on a block-shaped substrate having a small area is used as a holding member for the sliding member.

The above-mentioned molding and window glass stabilizer are shown in the drawing as shown in FIG. FIG. 1 is a side sectional view schematically showing a front door body of an automobile.
Here, (1) shows a window glass that slides up and down, and the glass is basically a reinforcing panel (3), (5).
The structure is supported by the door outer panel (4) and the door inner panel (2). The molding (M) is fixed to the tip portions of the panels (corresponding to the opening portions of the door body). Since the molding (M) has poor slidability only with the sealing rubbers (6) and (7), it is provided with slidability by having a flocked portion on the sliding contact surface with the window glass (1). However, not only the sealing property but also the sliding property is imparted.

[0006] (S) is a window glass stabilizer, which is a flock made of pile weave or the like on a U-shaped (cross-section) substrate (9) having a predetermined contact area made of rubber or the like. The window (10) is in contact with the surface of the window glass with a predetermined pressure to prevent the glass from vibrating.

By the way, as fibers for forming these flocked portions, polyamide fibers, polyester fibers, acrylic fibers, polypropylene fibers, fluorine fibers and the like are generally studied. Among them, polyamide fibers and fluorine fibers are preferred. It is used a lot.

[0008] For example, polyamide fibers and polyester fibers are often used as molding fibers. Although these have suitable wear resistance, there is an unsolved problem that an unpleasant noise is generated when the window glass is opened and closed, particularly an unpleasant noise is generated when the glass is opened and closed in the process of drying water droplets adhering to the glass. there were.

Further, for example, as a fiber for a window glass stabilizer, a fluorinated fiber is often used, and these fibers are excellent in slipperiness and the generation of unpleasant noise is reduced, but the flocked portion is durable. In many cases, the (abrasion resistance) was unsatisfactory, and for this reason, there were many inadequate scratches on the glass surface caused by dust, dust, vibration, rattling, etc.

[0010]

That is, the object of the present invention is to improve the durability of the flocked portion as well as the durability, and further to make a noise (uncomfortable noise) due to the sliding contact with the sliding member such as glass. The object is to provide a retainer for a sliding member that does not generate

BEST MODE FOR CARRYING OUT THE INVENTION "A relatively sliding member" means
In relation to the retainer of the sliding member, one in which at least one of them is movable, such as a window glass of an automobile, a photosensitive drum of a copying machine, a transfer drum (belt), various rollers, and various metals. Rolling, synthetic resin film formation, metal plates flowing in papermaking, synthetic films, paper, skis for artificial ski resorts, and the like.

On the other hand, the retainer for the sliding member according to the present invention is
It may be fixed or movable, and examples thereof include a window glass stabilizer for automobiles, a molding, and a cleaning member for copying materials.

The pressing member for the sliding member may be any member that has a flocked portion and that operates in contact with the sliding member. As long as it moves in this way, there are particular restrictions on the overall shape and usage. Not a thing.

Further, the restrainer having the flocked portion in sliding contact with the relatively sliding member (hereinafter referred to as sliding member) is, for example, a predetermined base cloth, a rubber elastic body, a thermoplastic elastomer, a foam, It is a member in which fibers are planted on a base material such as felt, cotton woven cloth, or hard plastic. here,
"Flocking" is basically a state of having a predetermined length and being fixed to the base body in the vertical direction, but what is flocked in an oblique direction to some extent may be mixed. The material and shape of the base cloth and the base body are determined by what is used as the retainer for the sliding member and what purpose the retainer for the sliding member is used for. It will be decided as appropriate.

The present invention has the greatest feature of the flocked fibers forming the flocked portion, which is especially 20 to 95% by weight, preferably 30 to 80% by weight of high density polyethylene and 80 to 5% by weight. Preferably, using a resin mixture containing, as a main component, a resin in which 70 to 20% by weight of an amorphous thermoplastic resin is mixed, this is made into fibers by melt spinning or the like, and is appropriately made into a flocked portion by a flocking means. Done by.

The high density polyethylene generally has a density in the range of about 0.945 to 0.975 produced by the medium to low pressure method, preferably 0.95 to 0.97.
In the range. The reason for using the polyethylene in this range (0.945 to 0.975) is to impart appropriate rigidity and slipperiness to the fiber of the present invention, and at the same time, formability (spinning) as the fiber is good. In addition, the purpose is to allow appropriate stretching for strengthening. As a high-density polyethylene having a density within the above range (0.945 to 0.975), "Hi-Zex, Type 210"
0JP "(Mitsui Petrochemical Industry Co., Ltd.) is exemplified.

On the other hand, the amorphous thermoplastic resin to be mixed with the high-density polyethylene has poor crystallinity as is generally said, and does not substantially take a crystal structure, and is not mixed with the polyethylene portion at the time of fiber molding. A material that is unlikely to cause peeling is preferable. Therefore, it is not limited as long as it is a resin having such properties, for example, polycarbonate, polystyrene, polymethyl methacrylate, polyvinyl acetate, polyvinyl chloride, polyether sulfone, polysulfone,
Examples thereof include polyarylate, polyamideimide, and polyetherimide, and may be a copolymer of acrylonitrile and styrene. Among these, polycarbonate is
It is preferable because it improves the heat resistance and moldability of the high-density polyethylene resin.

These amorphous thermoplastic resins are basically used alone or as a mixture of two kinds, but three or more kinds may be mixed.

Further, other crystalline resins, for example, aromatic polyesters such as polyethylene terephthalate and polybutylene terephthalate are contained in a small amount (for example, high density polyethylene and non-crystalline polyethylene) so long as the properties of the restrainer according to the present invention are not deteriorated. 10% by weight or less based on 100% by weight of the total thermoplastic resin). This may further improve chemical resistance and abrasion resistance. Further, it is possible to add a small amount of additives.

The mixing ratio of the high-density polyethylene and the amorphous thermoplastic resin is as described above, but the amount of the polyethylene is less than 20% by weight, that is, the amount of the amorphous thermoplastic resin is 80% by weight. When it exceeds the above range, the slipperiness is particularly deteriorated, and sliding noise tends to be generated in the rain. On the contrary, when the polyethylene exceeds 95% by weight, that is, the amount of the resin is 5% by weight.
If it is less than the above, the flocked fibers are easily detached due to the sliding resistance.

It should be noted that, when forming into a fibrous form, the high density polyethylene and the amorphous thermoplastic resin are mixed resins, but this mixing merely mechanically sufficiently mixes the pellets or powders of the two starting materials. Alternatively, the two resins may be mixed and melt-kneaded using a twin-screw kneading extruder.

Fiberizing of the mixed resin is generally carried out by melt spinning using a spinneret having a predetermined shape, but fibers which become slits in the film, that is, slit yarns may be used. Fiber cross-sectional shape, size (diameter)
Also, there is no particular limitation, and it is appropriately determined depending on the purpose and application. The melt spinning may be a monofilament or a multifilament, but it is preferable that the melt spinning is performed. This is to further improve the durability of the sliding member.

In many cases, the cross-sectional shape of the fiber is circular and the size is 20 to 100 μm (about 2 to 60 denier).
Fibers are used.

The above-obtained fibers are used for the flocked part in the retainer of the sliding member. The means for forming the hair-implanted portion is not particularly limited, but when roughly classified, the following two methods can be exemplified. That is, the first is a method by pile weaving or pile knitting using long fibers, and the second is a method by flocking using short fibers.

Here, the concrete method by pile weaving or pile knitting is, for example, polyester, Tetron,
A multifilament or monofilament fiber such as polyamide or polypropylene is used as a base fabric, and the filament of the present invention and the filament of the present invention are used as a pile portion for pile weaving or knitting, and the pile surface is used as a flocked portion.
Preferably, the pile surface is cut into a cut pile.

In this pile weaving / knitting method, it is not necessary to provide an adhesive layer as in the flock processing described later, and it is also possible to plant hair longer than the flock processing. It is a convenient way to make a retainer for a moving member.

Regarding the method of pile weaving / knitting,
Among the fibers of the present invention, the mixed composition ratio of the high density polyethylene and the amorphous thermoplastic resin as the main components is particularly 5
With respect to 0 to 95% by weight, the latter can be exemplified as a preferable range in which 50 to 5% by weight of fibers are used. High density polyethylene may be used in a high proportion for flocking by physical means without using an adhesive as in flocking, and it is not particularly necessary to consider the adhesiveness of fibers as in flocking. Is.

The pile may be formed by weaving or knitting, but the pile weave is preferable in that cut piles have uniform flock length and flock density. In either case of pile weaving or knitting, the pile may be single on one side or double on both sides.

Further, the flocking will be specifically described. In this method, short fibers are cut into short lengths in advance to obtain short fibers, and the fibers are planted on the surface of the substrate coated with the adhesive. Here, the flocking means is either spraying the fiber upright on the adhesive layer surface or electrostatic flocking by static electricity, and the flocking is completed by firmly bonding one end of the fiber. Here, in flocking, the substrate is knitted / woven fabric, rubber elastic body, various plastics, metal, glass, wood, leather,
A molded body made of paper or the like can be exemplified.

Regarding this flocking method, among the fibers of the present invention, when the total of the two is 100% by weight,
Especially 30 to 50% by weight of high density polyethylene and 70 to 5
It is possible to exemplify a preferable range in which 0% by weight of a fiber containing an amorphous thermoplastic resin as a main component is used. This is because the adhesiveness with the adhesive layer on the substrate is good.

The length of the flocked hair is determined depending on the purpose and application, but is generally about 0.2 to 8 mm. About this length, from the point of flocking property (meaning the upright state), about 0.3 to 3 mm is suitable for flocking, and conversely, in the case of pile weaving or pile knitting, 2 to 8 mm longer flocking is performed. Is possible.

Further, regarding the hair transplantation density, there is some difference in effect depending on the density. That is, if the flocking density is too coarse, there is a tendency to decrease particularly in terms of durability, while if too dense, the slipperiness tends to decrease. Suitable density ranges are 300-200,00
It is about 0 / mm ² . Considering that thick and rigid fibers reduce the flocking density, and thin and soft fibers increase the flocking density, an appropriate flocking density should be selected from such a range.

The holding member for the sliding member having the flocked portion thus obtained is determined in its overall structure and shape depending on the purpose and application. For example, when used as a window glass stabilizer for automobiles, since the purpose is to prevent vibration of the glass, such a sliding member is preferably such that the pile length of the base cloth is about 5 to 7 mm after cutting. After pile-weaving, the fabric is cut to a predetermined length to form a flocked portion, and this base cloth portion and an appropriate substrate such as plastic metal are bonded and fixed through a rubber sheet, a non-woven fabric, a sponge, etc., if necessary (see FIG. 2). The above can be exemplified, and this is preferably fixed in contact with the window glass in the door body.

When used as an automobile molding, the main purpose is to prevent water, dust, etc. from the outside from entering the door through the window glass. Therefore, a rubber sheet or the like is preferably used. An example is one in which an elongated member obtained by flocking the above-mentioned short fibers by electrostatic flocking is provided on a base body together with a base body such as a rubber for sealing at a door lip (opening of window glass).

The effect of the present invention will be described speculatively. When the surface of the fiber according to the present invention is observed with an electron microscope, it is observed that the high-density polyethylene and the amorphous thermoplastic resin are linearly oriented in the machine direction (spinning direction). Regarding this streak, it is not a straight line, but there are some parts that are bent or cut in some places, or have a fibril shape (sometimes it is almost straight without such a part being seen). Since they are arranged at random and appear to have a streak shape as a whole, the expression "streak shape" is used in the present invention for the sake of easy understanding. However, since such a surface state changes depending on the spinning temperature and the like, not all of them have such streaks.

Fibers used as a restrainer for conventional sliding members, such as fluorine-based fibers, have excellent slidability and are preferable when used as window glass stabilizers, but one more insufficient adhesiveness as molding fibers. In addition, there was also a phenomenon that the fiber was easily detached from the adherend substrate depending on the number of sliding times. In addition, although the polyamide fiber (nylon fiber) that has been used in the past has excellent adhesiveness and durability, it has another insufficient slipperiness as a molding fiber and produces unpleasant sliding noise. It was an easy situation.

By selecting the above-mentioned two kinds of resins according to the present invention, the high density polyethylene portion oriented in a streak shape on the fiber surface imparts slipperiness, and the amorphous thermoplastic resin oriented in a streak shape on the fiber surface, for example. Is thought to give adhesiveness,
Although it is presumed that it is possible to impart properties that conventional fibers do not have, it is presumed that this principle does not change even if the fibers are not oriented in a streak pattern. Furthermore, it is presumed that the wear resistance of the high-density polyethylene supplements the wear resistance of the amorphous thermoplastic resin, and conversely, the amorphous thermoplastic resin exhibits the property of complementing the bending resistance of the high-density polyethylene.
