The invention provides a method for weaving a fabric having a suspension effect. The method includes weaving preparation, guide bar allocation, and machine weaving. A separating type Jacquard comb alternatively puts yarns on a front needle bar and a back needle bar of a warp knitting machine to form loops so as to form patterns of the fabric; pattern change can be achieved without beaming, downward yarn winding, upward yarn winding, yarn entering, and chain block arrangement, and will not be limited by the number of cams and chain blocks of the warp knitting machine; the production cost is low, and the pattern types is various; the separating type Jacquard comb puts the yarns on the front needle bar of the double needle bar warp knitting machine to form loops so as to form a hollow structure on a spacing layer of the fabric, and then a good visual effect that the patters suspend in a surface layer and a bottom layer can be achieved, and the fabric has good stereoscopic impression. In addition, net hole tissues are woven on the surface layer and the bottom layer of the fabric, and then the surface layer and the bottom layer have a good perspective effect, and the suspension effect of the patterns can be enhanced.

A transmission screen through which an observer can see the side of the screen opposite to the observer side, and which has a sufficient viewing angle is provided. The transmission screen is a transmission screen 1 having a light diffusing layer 2 comprising a transparent binder and light diffusing elements contained in the binder, and the transmission screen is constituted so that the light diffusing elements should have a relative refractive index n of 0.75 or smaller or 1.25 or larger relative to refractive index of the transparent binder, both surfaces of the transmission screen 1 should be substantially smooth, and the transmission screen should have a total haze (JIS K7136:2000) of 10 to 85%.

The invention discloses a water permeable ground leveling machine. The water permeable ground leveling machine comprises a tractor chassis, a casing is arranged on the tractor chassis, a conveying device is arranged in the casing, and a material collecting box and a hanging device are separately installed at the rear end and the front end of the casing. The hanging device is connected to a leveling working head, the leveling working head includes a material receiving box body, auger sets are arranged on the material receiving box body, and a vibrating screen is arranged below the auger set. Ahydraulic discharging baffle is arranged at the bottom of the material receiving box body, telescopic cylinders are separately arranged at the two ends of the material receiving box body, sensor receiving mounting frames are connected to the upper portions of the telescopic cylinders, bending plates bent forward are installed on the outer walls of the telescopic cylinders, and adjustable scrappingplates are installed at the other ends of the bending plates. A leveling frame is arranged between the bending plates and the sensor receiving mounting frames, a first flattening roller is arranged at the bottom of the rear end of the leveling frame, a thorn roller with a plurality of metal thorns is arranged at the bottom of the front end of the leveling frame, and a second flattening roller isarranged on the middle portion of the leveling frame. By adopting the structure, the water permeable ground leveling machine realizes the effects that the structure is simple, the degree of mechanization is high, the efficiency is high, the water permeable effect is good, the construction accuracy and construction quality can be improved, and the labor intensity is reduced.

The invention discloses a permeable ground levelling machine which comprises a traction vehicle chassis. A housing is arranged on the traction vehicle chassis, and a conveying device is arranged in the housing. A material collecting box and a suspension device are mounted at the rear end and the front end of the housing correspondingly. The suspension device is connected with a levelling work headwhich comprises a material collecting box body. The material collecting box body is provided with auger sets, and a vibrating screen is arranged below the auger sets. A hydraulic discharging baffle is arranged at the bottom of the material collecting box body, and telescopic oil cylinders are arranged at the two ends of the material collecting box body. Sensor receiving mounting racks are connected to the upper portions of the telescopic oil cylinders, bent plates bent forwards are mounted on the outer walls of the telescopic oil cylinders, and adjustable scraper blades are mounted at the other ends of the telescopic oil cylinders. A levelling rack is arranged between the bent plates and the sensor receiving mounting racks. A first flattening roller is arranged at the bottom of the rear end of the levelling rack, a thorn roller with a plurality of metal thorns is arranged at the bottom of the front end of the levelling rack, and a second flattening roller is arranged in the middle ofthe levelling rack. The above structure is adopted, and the permeable ground levelling machine has the advantages of being simple in structure, high in mechanization degree, high in efficiency, good in perspective effect, and capable of improving the construction precision, the construction quality and lowering the labor intensity.
