Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail. Should be understood that, embodiment described herein, only for instruction and explanation of the present invention, is not limited to the present invention.
The present invention provides a kind of friction cloth, and provides its enforcement mode. As shown in Figure 1, in the present embodiment, described friction cloth comprises cloth body 10 and the bristle 11 being arranged on described cloth body 10, and the material of described bristle 11 is at least two kinds; That is, dividing according to material, the kind of described bristle 11 is at least two kinds. In the present embodiment, described at least two kinds of bristles 11 intersection is arranged.
It is understandable that, the characteristics such as the diameter of the bristle 11 of unlike material, hardness, stretching dynamics are different, when at least two kinds of bristles 11 intersect setting, the rubbing characteristics of the friction cloth that different bristle 11 mixes composition can be different from above-mentioned at least two kinds of bristles the friction cloth being made up of any one independent bristle such that it is able to obtains the friction cloth with new rubbing characteristics; And, by the ratio controlled between different types of bristle, and then regulate the rubbing characteristics of friction cloth, enable the intersect friction cloth of composition of at least two kinds of bristles 11 have the advantage of different bristle 11 concurrently, thus in friction orientation technique, obtain good orientation effect.
Specifically, as shown in Figure 1, the material of described bristle 11 can comprise cotton and nylon; That is, described bristle 11 comprises cotton bristle 110 and nylon brush hair 111. In actual orientation technique, owing to the hardness of cotton bristle 110 is less, the action intensity between itself and PI film is less, and the Zara class foreign matter of generation is also less, but correspondingly, the homogeneity of the orientation groove that it is formed is poor, it is easy to cause Mura bad; And the density of nylon brush hair 111 is relatively big, having good friction effect between itself and PI film, the homogeneity of the orientation groove formed is better, but correspondingly, it also can produce more Zara class foreign matter. And in the present embodiment, by cotton bristle 110 together with nylon brush hair 111 combined crosswise, by the ratio of control cotton bristle 110 and nylon brush hair 111, the homogeneity of orientation groove formed can be made on the one hand better, the Zara class foreign matter also making to produce on the other hand is also less, thus avoids the problem because of the alignment films of preparation to cause occurring that display is bad.
Specifically, as shown in Figure 2, described cloth body 10 is for by the reticulated structure woven to the warp 100 arranged with the parallel 101 arranged along second direction along first party; Described bristle 11 is wrapped on described warp 100.
And the canoe between described bristle 11 and cloth body 10 can as shown in Figure 3, namely every root bristle 11 is wrapped on a warp 100, V-shaped structure; Can also as shown in Figure 4, namely every root bristle 11 is wrapped on adjacent three piece warp 100, and in these three warps 100, is positioned at the both sides that a middle warp 100 and all the other two warps 100 lay respectively at described bristle 11, in W type structure.
Specifically, in the present embodiment, the density content of described cotton bristle 110 and nylon brush hair 111 at 1:1��1:3, so that in friction orientation technique, both PI film being had enough action intensities, can ensure that again the Zara class foreign matter produced is less.
Friction cloth in the above-mentioned enforcement mode of the present invention, its cloth body 10 arranges the bristle 11 of at least two kinds of materials, and bristle 11 intersection of unlike material is arranged, the rubbing characteristics of described friction cloth is enable to be different from the friction cloth being made up of the bristle of independent a kind of material; Further, by controlling the ratio of the bristle 11 of unlike material, it is possible to regulate the rubbing characteristics of friction cloth, thus in friction orientation technique, it is possible to select the friction cloth with individual features, prepare satisfactory alignment films, ensure display effect.
The present invention also provides a kind of friction orientation equipment, and it comprises friction roller and friction cloth, and described friction cloth is wrapped on described friction roller, and, the friction cloth that the above-mentioned enforcement mode of described friction cloth the present invention provides.
Friction orientation equipment in embodiment of the present invention, it adopts the friction cloth that the above-mentioned enforcement mode of the present invention provides, it is possible to regulate the rubbing characteristics of friction cloth, thus selects the friction cloth with individual features, prepares satisfactory alignment films, ensures display effect.
It should be appreciated that the illustrative embodiments that above enforcement mode is only used to the principle of the present invention is described and adopts, but the present invention is not limited thereto. , it is possible to make various modification and improvement, for those skilled in the art, without departing from the spirit and substance in the present invention these modification and improvement are also considered as protection scope of the present invention.
