The invention relates to a ramie high-temperature gas explosion degumming process. The process applies degumming process, and the degumming process applies alkali solution. The degumming process is characterized in that degumming process includes unpacking and unbinding process, feeding process, first high-temperature gas explosion process, first extruding process, second high-temperature gas explosion process, second extruding process, third high-temperature gas explosion process, and third extruding process, wherein a high-temperature high-pressure flushing method is applied; ramie is flushed under the alkali solution in the first high-temperature gas explosion process, the second high-temperature gas explosion process and the third high-temperature gas explosion process; the alkali solution temperature is kept at 80-90 DEG C or 95-100 DEG C; the alkali solution pressure is kept at 0.8-1.0 MPa or 1.0-1.2 MPa; the heat preservation and pressure maintaining times of the alkali solution are 3-5 minutes or 5-10 minutes. The process cancels the binding, packing, softening, and loosening processes, shortens the technical flow, promotes quality of the degummed ramie, improves production efficiency, decreases cost and reduces environmental pollution.

The invention discloses a western-style clothes front shirt and liner molding die and a manufacturing method thereof. The western-style clothes front shirt and liner molding die comprises a first template, a clamping plate and a second template; the first template, the clamping plate and the second template are successively superposed and form turnover movable connection at one end, and needle walking grooves are formed in the first template, the clamping plate and the second template; the portions between the clamping plate and the first and second templates are respectively used for clampinga liner and a front shirt; a first protrusion, a second protrusion, a third protrusion and a fourth protrusion are arranged on the clamping plate along the needle walking grooves; the first protrusion is used for increasing remaining amount of a lapel corner of the liner; the second protrusion is used for increasing folding amount of a fold line of a lapel; the third protrusion is used for increasing loose amount of a lapel seam allowance end; the fourth protrusion is used for making a lower hem of the front shirt be concave after molding of the lower hem of the front shirt. Smoothness of theprepared western-style clothes front shirt and liner is better, the close-fitting characteristic of the lower hem of the front shirt and lapel is better, the lapel at the lapel corner position and the lapel fold line position is more close-fitting and cannot easily upwarp, the operation is simple, the production efficiency is higher, and the consistence of product quality is better.

The invention relates to the technical field of fiber preparation and production, in particular to a drying treatment machine for the preparation of regenerated protein cellulose fibers, including a drying box, a limit block, a pulling device, a driving motor, a barrier device and an air intake device. The drying box It has a rectangular structure, and the inner wall of the drying box is symmetrically installed with a limit block up and down near the left end, and a pulling device is arranged on the right side of the limit block. The invention can solve the problem that the existing machinery usually directly dries the fiber by hot air when drying the regenerated protein cellulose fiber, but the hot air cannot directly dry the inner fiber, thereby reducing the fiber drying rate and the like. The pulling device used in the drying treatment machine for the preparation of regenerated protein cellulose fibers provided by the present invention can pull the fibers up and down, thereby increasing the gap between the fibers, allowing the inside and outside of the fibers to be dried quickly at the same time, improving the The rate at which fibers are dried.

The invention provides a system device for directly and effectively spray-drying high-solid-content sludge, which comprises a hopper, wherein the hopper is connected with a feed pump and used for feed agitation, the feed pump is connected with one end of a nozzle in a spray drying tower through a pipeline, and the other end of the nozzle is connected with an air compressor; an air inlet at the lower part of the spray drying tower is connected with a hot blast furnace through the pipeline, the top of the spray drying tower is connected with a dust remover through the pipeline, the dust removeris connected with a smoke gas wet recovery tower through the pipeline provided with an exhaust fan, and the recovery tower is communicated with a pool arranged at the bottom of the recovery tower anda nozzle at the top through the pipeline provided with a water pump. The invention also provides a method adopting the system device for directly and effectively spray-drying the high-solid-content sludge. The invention has the effects that the energy consumption is low by using the method, and the atomized sludge has small grains, uniform diameter, good drying effect, high loosening degree and high porosity and is markedly superior to other drying forms. The produced drying sludge is adaptable to the paths of combustion heating, cement manufacture, greening, landfill and the like.
