Design method of micro texture having flat wall surface drag reduction function

The invention discloses a design method of a micro texture having a flat wall surface drag reduction function, and belongs to the field of surface texture design. According to the gas flow rate, an area, namely a buffer layer between a viscous bottom layer and a logarithmic law layer, where the wall shear stress is generated is determined by combining a boundary layer theory. Dimensionless treatment is performed on the size, and the thickness of the buffer layer is calculated so as to determine the height range of the micro texture. According to a Reynolds formula, the critical point of the fluid flowing from the laminar flow to the turbulent flow is calculated, and the arrangement area range of the micro texture is obtained. According to the two data, resistance reduction micro texture design is carried out, CREO software modeling is utilized, simulation is carried out through flow field simulation software FLUENT, the micro texture resistance reduction situation is analyzed, characteristic parameters of the micro texture are optimized, and the design of the flat-wall resistance reduction micro texture with the resistance reduction effect is achieved. The boundary layer theory isadopted, micro texture parameter design is conducted through layering and positioning of the turbulence area, the size design range of the drag reduction micro texture can be effectively narrowed, thesimulation amount is reduced, and the resource cost is saved.

The invention discloses a wood flour-filled modified polypropylene material with low odor and an imitation flocking effect, and a preparation method thereof. The wood flour-filled modified polypropylene material is prepared from the following components in percentage by weight: 40 to 99 parts of polypropylene resin, 0 to 40 parts of ore body powder, 0 to 20 parts of flexibilizer, 0.5 to 10 parts of wood flour, 0.1 to 1 part of antioxidant, and 0.1 to 0.5 part of light stabilizer. Compared with the prior art, the wood flour-filled modified polypropylene material provided by the invention has the following positive effects that (1) the wood flour is adopted to replace chemical staple so as to be added into the light-colored modified polypropylene material, a texture design is combined to have the imitation flocking effect, and a wood flour grid or a hollow structure can adsorb odor, so that not only is the material odor reduced, but also a light wooden fragrance can be produced. The material can replace an interior trim part product coated with textile fabrics, so that not only is the production cost of auto parts manufacturers saved, but also the high requirements of consumers on smell and vision effects of automotive interior trims are greatly met. (2) Less wood flour is added, so that the wood flour is not easy to precipitate out and has no influence on a physical performanceof the material.

Low-odor and flocking-effect-imitating plant straw powder filled modified polypropylene material and preparation method thereof

The invention discloses a low-odor and flocking-effect-imitating plant straw powder filled modified polypropylene material and a preparation method thereof. The low-odor and flocking-effect-imitatingplant straw powder filled modified polypropylene material is prepared from the following components in percentage by weight: 40 to 99 parts of polypropylene resin, 0 to 40 parts of ore body powder, 0to 20 parts of a toughening agent, 0.5 to 10 parts of plant straw powder, 0.1 to 1 part of an antioxidant and 0.1 to 0.5 part of a light stabilizer. The low-odor and flocking-effect-imitating plant straw powder filled modified polypropylene material disclosed by the invention has the following positive effects that 1, chemical staple fibers are replaced with the plant straw powder; the plant strawpowder is added into the light-color modified polypropylene material, and a texture design is combined, so that the material has a flocking-effect-imitating effect; a hollow structure of the straw powder has an adsorption effect on odor so that the odor of the material is reduced and a slight wheat aroma also can be generated. The material disclosed by the invention can be used for replacing a textile fabric covered interior part product; the production cost of automobile part manufacturers is saved and high requirements of consumers on smell sense and vision of automobile interior parts aregreatly met; 2, the amount of the added plant straw powder is relatively small and the plant straw powder does not easily separate out, so that the plant straw powder has no influence on physical performance of the material.

The invention relates to a production method for improving anti-crease effect of pure-cotton popline dyed fabric. Sample cloth is the pure-cotton popline dyed fabric, and the texture specifications of the pure-cotton popline dyed fabric include that the fabric texture is formed by 1/1 plain lines, 2/1 slope lines, 2/2 slope lines, 3/1 slope lines, 1/1 plain back plus 2/1 slope lines or 1/1 plain back plus 3/1 slope line texture, yarn count is 40-90 British count sub-thread yarns or 80-180 British count double-thread yarns, warp density is 120-230 thread/inch, weft density is 70-130 thread/inch, weaving difficulty coefficient is 28-37, and the ratio of the warp density to the weft density is 1.5 to 1.9. The production method is characterized by including steps of modifying pattern texture design, spinning raw cotton, dyeing, weaving, burning, mercerizing, tentering, preshrinking and obtaining a finished product. The finished fabric is ecological and environment-friendly after being processed without adding any resin and catalyst by the production method. Since the warp density and the weft density are lowered, cost is reduced, the finished fabric is light and thin, moisture absorbing permeability is improved by more than 30%, and wearing performance is good.

The invention discloses a method for producing true-color jacquard fabrics through a double-design method. The method for producing the true-color jacquard fabrics through the double-design method applies the double-design method to complete color pattern design and loom weaving of fabrics and comprises the following steps of 1) selecting and setting a bitmap file as a bitmap file A with a heightof M, a width of N, a warp density (Pj) of P, a weft density (Pw) of Q, a warp number of N*P and a weft number of M*Q; 2) performing first design; 3) performing second design. The method for producingthe true-color jacquard fabrics through the double-design method breaks through the design steps of traditional pattern weaving, skillfully combines artistic retouching and technological design, corresponds well to computer color modes, embodies fabric color, facilitates texture design, achieves secondary transformation of design, separates design from patterns and totally breaks traditional design concepts. Besides, the method for producing the true-color jacquard fabrics through the double-design method is simple and intuitive in design, greatly reduces the workload of design processes, improves the production efficiency, reduces the production costs and enables design ideas to turn into real woven products rapidly, thereby being an important innovative achievement.
