The invention discloses a natural fiber composite health-care cushion which comprises a middle layer. A surface layer is arranged on the upper surface or the lower surface of the middle layer. A block layer is arranged between the middle layer and the surface layer. The surface layer is a non-woven layer comprising 5 percent to 50 percent of low melting point fibers. The middle layer is a non-woven layer which comprises the following components: bastose and 5 percent to 50 percent of low melting point fibers. The block layer is a non-woven layer comprising 5 percent to 100 percent of low melting point fibers. In the natural fiber composite health-care cushion, the content of the bastose is within the range of 5 percent to 65 percent. The invention also discloses a preparation method of the natural fiber composite health-care cushion, which comprises the following steps of: respectively preparing the middle layer, the upper or lower surface layer and the block layer; then sequentially paving the layers; and preparing the natural fiber composite health-care cushion by processes of processing by an oven, cold milling, cooling, cutting, inspecting and packaging. Due to the adoption ofthe natural fiber composite health-care cushion and the preparation method thereof, which are disclosed by the invention, the problem that the existing mattress is easy to affect with damp, mildew, breed worms and deteriorate, is easy to layer, has poor air permeability and is discomfortable to use due to protruded hard fibers in the middle of the mattress is solved.

The present invention provides a telescopic conveyor (1) having at least two conveyor belts (10). Said belts are arranged one above the other and can be moved relative to one another in the longitudinal direction. Each conveyor belt (10) here has a frame (11), a circulatory belt (12) and a first deflecting roller (13) at a first end (A), and a second deflecting roller (14) at a second end (B), ofthe conveyor belt (10), wherein the second end (B) is a transfer end of the conveyor belt (10), and wherein a bridging device (2', 2) is provided between in each case two adjacent conveyor belts (10)located one above the other, and said device bridges, at least to some extent, the difference in height (H) between the two conveyor belts (10) arranged one above the other, it being necessary for said difference in height to be overcome at the transfer end. The bridging device (2) comprises a ramp (3, 3') with a slope (S) and also a first deflecting roller (4), which is arranged at the higher endof the ramp (3, 3'), as well as a first holding-down device (5), which is arranged beneath the first deflecting roller (4), and also a second holding-down device (7) at the foot of the ramp (3, 3').The circulatory belt (12) of the respectively lower conveyor belt (10) is guided, from a conveying plane (E1) beneath the second holding-down device (7), over the ramp (3, 3') with the slope (S) and,from there, is deflected over the first deflecting roller (4) and guided back to the conveying plane (E1) beneath the first holding-down device (5). The slope (S) of the ramp (3, 3') continues in stepless fashion tangentially along the circulatory belt (12) of the conveyor belt (10) located above, said circulatory belt being guided over its second end-side deflecting roller (14).

The invention discloses an environment-friendly single-layer board for home decoration and a manufacture method of the environment-friendly single-layer board. The environment-friendly single-layer board is composed of 50-80 wt% of fibrilia, 20-50 wt% of low melting point fiber and 0-30 wt% of Alpinia speciosa fiber. The manufacture method of the environment-friendly single-layer board comprises weighing, pre-opening, mixing, fine-opening, automatic cotton feeding, pre-forming of nets, air laying, upper needling, lower needling, heat bonding in a drying oven, cold rolling, cooling, cutting, inspection, packaging and other procedures. The environment-friendly single-layer board is directly formed by the low melting point fiber and the fibrilia in a composite mode, no other ingredient is added, and therefore the fact that the environment-friendly single-layer board does not contain other harmful chemical substances is guaranteed, and the environment-friendly single-layer board is harmless to a human body and environmental friendly. The fibrilia has good moisture absorption and air permeability properties and is antimicrobial and resistant to mites, thereby being especially suitable for being used as an environment-friendly home decoration material. The environment-friendly single-layer board is light in weight, the gram weight can reach 100-500 grams per square meter, the thickness is in the range of 0.2-5 millimeters, the hardness is high, and therefore the environment-friendly single-layer board can be used for directly replacing wallpaper, oil paint, coatings and other decorating materials and can be directly used on walls, roofs and other places which need decorating.
