The invention provides a chestnut mechanical refrigerator humidity-adjusting storage and preservation method. The method comprises the steps of: pre-cooling harvested chestnuts in a refrigerator by reducing the temperature in steps, wherein relative humidity in the refrigerator during pre-cooling is over 90 percent; when the chestnuts are pre-cooled in the refrigerator by reducing the temperature in steps to the refrigerator temperature, starting to sub-pack jute bags of lining preservative films, and then adjusting the temperature in the refrigerator to 3 DEG C to minus 1 DEG C for pre-cooling; after pre-cooling, keeping the temperature in the refrigerator at minus 3 DEG C to minus 1 DEG C and the humidity of over 90 percent, storing for 30 to 40 days under the conditions, and adjusting the relative humidity of the refrigerator to 75 to 85 percent, and keeping the humidity in the whole storage period. By the chestnut storage and preservation method, the storage time of the chestnuts can be greatly prolonged, and problems of water loss, mildew and worms in long-time storage of the chestnuts can be solved.

The invention relates to a manufacturing method of a seat cushion made of jute fiber. The method comprises the following steps: firstly, the soaking is performed to jute in compound enzyme water solution prepared by pectase and laccase, and the weight ratio of the compound enzyme water solution and the jute is 12 : 1 to 40 : 1; the pH value of the compound enzyme water solution is firstly adjusted into 4.0 to 6.5, and the compound enzyme water solution is warmed up to 35 to 65 DEG C, and the temperature is kept for 20 to 120 minutes; and then pH value of the compound enzyme water solution is adjusted to more than 8.0 and less than and equal to 9.5, and the compound enzyme water solution is kept for 20 to 120 minutes at 14 to 70 DEG C; then the enzyme inactivation process is performed to the jute processed through the compound enzyme; secondly, jute fiber after being degumed is mixed with chemical fiber, and carding, mesh placement and needling are performed to the chemical fiber; thirdly, the mixed fiber after being needled is thermally pressed and molded; fourthly, a sleeve body is coated. The seat cushion manufacuted by the invention is soft and comfortable, has no urtication feeling when being used by people, and has good antibiosis and anti-acarine performance.

The invention relates to a method for producing handicraft processing paper using recycled fiber, which is an optimization of the traditional kraft paper preparation method, using waste newspapers as raw materials to prepare recycled fiber pulp, and the amount of recycled fiber used reaches 50%, reducing the amount of virgin fiber. It can save wood and be friendly to the environment. Adding a special reinforcing agent, in addition to significantly improving the physical strength of the handicraft processing paper, can also make the handicraft processing paper not easy to grow insects and mildew; adding dyes makes the color of the handicraft processing paper can be adjusted according to user preferences; The handicraft processing paper has high appearance quality, good strength and strong tensile force, and can be directly used for handicraft processing.

The invention relates to a method for producing mattress by using tossa, which comprises following steps that 1, the tossa undergoes via complex enzyme degelatinizing process, while the complex enzyme degelatinizing process uses the complex enzyme water solution prepared from pectic enzyme and laccase to degelatinize tossa, which first adjusts the pH value of the complex enzyme water solution not lower than 4.0 but lower than 5.0, and increases temperature to 35-65DEG C and holds the temperature for 20-120min, then adjusts the pH value of the solution to 7.5-9.5, and holds the pH value under 40-70DEG C for 20-120min, and then inactivates the treated tossa, 2, the degelatinized tossa is mixed with chemical fiber, and the mixed fiber undergoes the processes of carding, mesh placement and needling, 3, the needled mixed fiber is thermally pressed and shaped. The inventive mattress is flexible and convenient, without bad feeling, while the mattress has better antibiosis and mite-proof functions.

The invention discloses an embroidering method of a Zhuang-nationality applique, belonging to the technical field of embroideries. The embroidering method comprises the following steps of A, shearing patch patterns according to a designed pattern, then, pasting all the patterns onto a fabric shell, and respectively shearing all fabric shell patches; B, respectively wrapping and pasting silk fabrics with corresponding colors outside all fabric shell patches prepared in the step A; C, embroidering corresponding detail grains on the patches prepared in the step B; and D, respectively pasting the patches embroidered in the step C on a base fabric according to the pattern, and embroidering the outer edges of all the patches and the base fabric together by using corresponding embroidery threads to obtain the Zhuang-nationality applique. By using the embroidering method, the problems of poor third dimension and reality sense as well as expression and rendering insufficiency in an embroidery can be solved.
