The composite contains the CNF having a sulfate ester group and the CNC having a sulfate ester group.

The present invention relates to a fiber for fabric authenticity identification and a fabric authenticity identification system using the same, the fiber for fabric authenticity identification comprising an infrared light-emitting body, the fiber being included in a yarn or a fabric, the fiber having a function of fabric authenticity identification by mixing a special pigment with the fiber, and the fabric authenticity identification system using the same. Therefore, the effect of authenticity identification or counterfeiting prevention can be achieved. For example, for a specific functional product, analysis after fabric preparation becomes complex and infeasible, but rapid and accurate identification can be achieved through the fiber for fabric authenticity identification of the present invention.

The utility model discloses a precise needle head double-air-passing filter which comprises an upper shell, a lower shell and a protective cap, the upper shell is arranged on the lower shell, and the protective cap is detachably arranged on the upper shell; the upper shell is provided with a bolt part, a first flow channel, a first exhaust hole and a first half cavity; the lower shell is provided with a nipple, a second flow channel, a second exhaust hole and a second half cavity; the novel needle head double-air-passing filter has the advantages that the use is convenient, the manufacturing cost is low, the exhaust time before injection is shortened, the bidirectional air passing function is achieved, the contradiction between medical care and patients is reduced, the service satisfaction degree of the medical care personnel is improved, the time for the medical care personnel to inject and rescue the patients is saved, and whether air exists after injection or not is not worried. In addition, a direct fixing method is adopted to change a traditional hot welding film fixing method, so that the physical and chemical characteristics of the film are kept, and the production cost is saved while the gas passing function is better realized.

The invention discloses a tea substitute for reducing uric acid and assisting in the treatment of gout, comprising by weight: 55-90 parts of black tea, 12-18 parts of Codonopsis pilosula, 12-18 parts of Smilax glabra, 12-18 parts of water flos floridis, 12-18 parts of Hibiscus mutabilis leaves, 8-12 parts of corn silk, 8-12 parts of dandelion, 8-12 parts of Momordica grosvenori, 5-10 parts of hawthorn, 5-10 parts of yam, 3-8 parts of wolfberry, 3-8 parts of Eucommia ulmoides, and 2-5 parts of Sargassum polysaccharide. The Chinese medicinal ingredients are reasonably matched according to the monarch, minister, assistant and envoy theory, Sargassum polysaccharide has certain viscosity, stability and antioxidant properties, helps to maintain the physical properties and texture stability of the product, and the black tea base is compounded with a variety of Chinese herbal medicines and Sargassum polysaccharide for taking, has good uric acid reduction and inhibitory effects, and can be used for assisting the prevention and treatment of gout.

The utility model relates to the field of buildings, and discloses a structure for preventing large-area pile loading from generating lateral stress on a building foundation, which comprises a pile foundation consisting of a foundation pile and a bearing platform, a loading surface is arranged on the bearing platform, an isolating layer is arranged between the loading surface and the foundation pile, and the isolating layer comprises an isolating cavity. The isolation cavity is internally provided with filler, and lateral stress borne by the building foundation can be reduced through deformation of the filler. Through the arrangement of the isolating layer, the problem of solving stress measurement through the traditional thinking of resisting is converted into the problem of reducing the stress measurement of large-area pile loading on the pile foundation through the thinking of unloading, so that the pile diameter and the pile number are effectively reduced, the engineering amount is reduced, and the economical efficiency is improved.

The invention relates to the technical field of plastic processing, and discloses an environment-friendly production process of a low-melting-point plastic product, which specifically comprises the following steps: 1, mixing treatment: mixing plastic raw material particles with an environment-friendly additive in a specific proportion to reduce the melting point of the plastic raw material particles and maintain the physical properties of the plastic raw material particles to obtain a mixed raw material; 2, melting treatment: feeding the mixed raw materials into melting equipment for melting treatment to obtain the raw materials after melting treatment; 3, plasticizing and extruding: plasticizing and extruding the molten raw materials through special processing equipment to form a required plastic product; 4, temperature and pressure control: in the extrusion process, controlling the temperature and the pressure to ensure that the melting point of the plastic product meets the preset low melting point requirement; by means of the process, the problems of energy consumption and environmental pollution in the production process of the plastic product with the low melting point can be remarkably solved, waste generated in the production process is reduced, and the material utilization rate is increased.
