Rotor spinning melange yarn forming method and device and product

The invention discloses a rotor spinning melange yarn forming method and device and product. On a rotor spinning machine, two or more fiber strips enter a feeding mechanism through a striping gate and a horn mouth, the feeding mechanism contains at least two independently controlled feeding rollers and can control the independent feeding of at least two fiber strips, different fiber strips are of different colors, or of different color combinations, or of different fiber components, the feeding speed of each fiber strip is controllable, the feeding can be conducted at different time sections, and the feeding speeds of all the fiber strips are independently changeable or simultaneously changeable; through the implement of continuous constant-speed feeding or segmentation variable speed feeding of different fiber strips, continuous constant feeding or segmentation variable feeding of the fiber strips is controlled; the fed fiber strips break away from a combing roller, are transferred to a delivery pipe, and then enter a spinning cup depending on the centrifugal force of the combing roller and the action of added air flow after the opening and carding actions of the combing roller; single fibers of different components are mixed, condensed and twisted in the spinning cup to form rotor spinning melange yarn blended by monochrome or polychromatic fiber, or with segmentation color effect, uniform linear density or changing linear density.

Process for spraying plastic parts of mobile phone and mobile phone shell made by adopting process

The invention discloses a process for spraying plastic parts of a mobile phone. The process comprises the following steps of (1) assembly of an oil injection clamp; (2) cleaning; (3) electrostatic dust collection; (4) spraying of primer; and (5) oil injection on finishing paint. The invention also discloses a mobile phone shell made by adopting the process. The process is easy to operate, the primer of a corresponding color is selected according to the required color effect, the spraying frequency is lowered, the consumption of the pigments is reduced, and the production efficiency is improved, the production cost is lowered; and due to the adoption of the steps of cleaning and electrostatic dust collection, the adhesive force of the primer and the finishing paint is improved, the spraying effect is effectively improved, and the product quality is guaranteed. The mobile phone shell has a reasonable structure; due to the combination of the primer and the finishing paint, the primer is used for showing the required color effect, the finishing paint is used for improving the crash resistance and the wear resistance of the mobile phone shell, and the service life is prolonged. The spraying process is simple, low in cost and convenient to produce, and large-area popularization and application are facilitated.

Warp knitting machine for producing single layer structure three-dimensional jacquard weave vamp, and production method thereof

The invention discloses a warp knitting machine for producing single layer structure three-dimensional jacquard weave vamp, and a production method thereof. The production method includes: designing a vamp sample according the design demands of all the parameters; performing designing through CAD software, converting the design data into a machine file which can be read by the warp knitting machine, and inputting the machine file into the warp knitting machine; arranging jacquard combs in the center of the machine, and arranging ground combs at two sides of the jacquard combs; allowing guide bars to knit after threading, wherein each jacquard combs knit three stitches to form a loop stitch, the ground combs knit one stitch to form a weft-insertion or a warp chain stitch; allowing the jacquard combs to perform co-directional or reverse yarn laying, and correspondingly allowing the ground combs to take part in knitting; performing finishing to obtain single layer structure three-dimensional jacquard weave vamps. The obtained single layer structure three-dimensional jacquard weave vamps are clear in l jacquard weave effect, and is high in stereoscopic impression of patterns; the single layer jacquard weave vamps adopt polyamide polyester as a raw material to achieve a dual-color effect, and can be composited with three-layer structure or single-layer structure plain net fabric to achieve a richer color effect in later; and the single layer structure three-dimensional jacquard weave vamps are excellent in stiffness and wear-resisting property, can achieve a good reliability after composited with the other fabrics.

Method and device for compensative adjustment of pixel data and liquid crystal display panel

An embodiment of the invention discloses a method for compensative adjustment of pixel data. The method includes a step 1 of receiving pixel original gray scale data of a to-be-displayed image; a step2 of querying a first compensation table for each pixel original gray scale data so as acquire a first gray scale value and a second gray scale value corresponding to each sub pixel original gray scale data; a step 3 of querying a second compensation table so as to acquire a first adjustment value and a second adjustment value corresponding to each sub pixel original gray scale data in the pixels; a step 4 of performing adjustment on the first gray scale value of each sub pixels in the pixels with the first adjustment value so as to acquire a first gray scale value of said sub pixel subjectedto adjustment; performing adjustment on the second gray scale value with the second adjustment value so as to acquire a second gray scale value of said sub pixel subjected to adjustment; a step 5 ofdisplaying the first gray scale value and the second gray scale value subjected to adjustment of each sub pixel of each pixel. The invention also discloses a corresponding device and a liquid crystaldisplay panel. By applying the invention, the screen view angle can be enlarged, pixel granular sensation can be reduced and side view color effect can be improved.
