Aqueous polyurethane superfine fiber synthetic leather and preparation method thereof

The invention relates to aqueous polyurethane superfine fiber synthetic leather and a preparation method thereof. The preparation method comprises the following steps of: firstly, adding the following components according to parts by weight, i.e. 2-5 parts of foaming agents, 50-200 parts of water, 2-3 parts of foam stabilizers and 0-3 parts of waterborne colorants, into 100 parts of aqueous anionic polyurethane dipping sizing agents, and stirring the components and the sizing agents uniformly at high speed by using a blender so as to prepare a sizing agent; secondly, dipping non-woven fabricsin the sizing agent, scrapping the surface of the fabrics and keeping partial cells; thirdly, solidifying aqueous polyurethane on the dipped non-woven fabrics through aqueous coagulating liquid so asto form cells; fourthly, carrying out water scrubbing after aqueous polyurethane resin is completely solidified, and drying the aqueous polyurethane resin by an infrared drying oven so as to obtain base cloth; fifthly, treating the dried base cloth through an alkali reducing process; sixthly, treating the base cloth treated through the alkali reducing process through an postprocessing process; and seventhly, preparing the obtained base cloth into the synthetic leather. The aqueous polyurethane superfine fiber synthetic leather is prepared by the method.

Drive control system for a fiber-based plasma display

A full color fiber plasma display device includes two glass plates sandwiched around a top fiber array and a bottom fiber array. The top and bottom fiber arrays are substantially orthogonal and define a structure of the display, with the top fiber array disposed on a side facing towards a viewer. The top fiber array includes identical top fibers, each top fiber including two sustain electrodes located near a surface of the top fiber on a side facing away from the viewer. A thin dielectric layer separates the sustain electrodes from the plasma channel formed by a bottom fiber array. The bottom fiber array includes three alternating bottom fibers, each bottom fiber including a pair of barrier ribs that define the plasma channel, an address electrode located near a surface of the plasma channel, and a phosphor layer coating on the surface of the plasma channel, wherein a luminescent color of the phosphor coating in each of the three alternating bottom fibers represents a subpixel color of the plasma display. Each subpixel is formed by a crossing of one top fiber and one corresponding bottom fiber. The plasma display is hermetically sealed with a glass frit. The sustain and address electrodes are brought out through the glass frit for direct connection to a drive control system.
