Techniques that provide cost effective optical fiber communication links for HDCP transmission systems and the like are provided. A single fiber for bidirectional communication is enabled, without wavelength selective unit to achieve the HDCP transmission. One embodiment of the present invention has a forward channel using a light source (e.g., VCSEL at about 850 nm) in the GHz modulation level (e.g., 1 GHz or greater), and a corresponding photodetector. The backward channel has a light source (e.g., LED at 630 nm) in the MHz modulation level (e.g., 10 MHz or less), and a corresponding photodetector. One application is for realizing a home entertainment system (e.g., DVD player and high definition television) that employs an HDCP-enabled communication link to transmit copy restricted digital content.

The invention discloses a textile fiber carding machine which comprises a feeding mechanism, a pre-carding mechanism, a main carding mechanism and a web forming mechanism, wherein the feeding mechanism comprises a feeding curtain; a rack conveyor belt is arranged in the feeding curtain; the feeding curtain is connected with a feeding roller I and a feeding roller II through the rack conveyor belt; the pre-carding mechanism comprises an opening roller, an opening cylinder, a working roller I, a working roller II, a wool stripping roller I, a wool stripping roller II and a wool stripping roller III; the feeding roller I and the feeding roller II are mutually connected with the opening roller in a matched manner; and the opening roller is mutually connected with the opening cylinder in a matched manner. The textile fiber carding machine is reasonable in process, the fibers are sufficiently carded, the single fiber rate is high, and uniformity of fiber webs is good; and the working roller and the stripping roller for roller type carding are used for carding and mixing fibers, so that the yield is high.

The invention discloses a touch cool feel type polyester fiber fabric. The fabric comprises touch cool feel polyester fiber, wherein the polyester fiber is core and sheath composite fiber, the core component of the fiber is polyester, the sheath component of the fiber is a polyester composition containing PVP (poly vinyl pyrrolidone), the area ratio of the core component and the sheath component of the cross section of single fiber is 90/10 to 60/40, the thickness of the sheath component is 0.5-10mu. m, the weight of the PVP accounts for 3-12wt% of the polyester fiber, and the content of core and sheath type composite polyester fiber is more than 30wt% of the total amount of the touch cool feel type polyester fiber fabric. The touch cool feel type polyester fiber fabric has the advantages that the touch cool feel is good and durable, and the touch cool feel type polyester fiber fabric can be applied to clothes, such as underwear and sports clothes.

A molding fiber-reinforced resin material for a fiber-reinforced resin material which comprises reinforcing fiber bundles A and a matrix resin, and a production method therefor are disclosed. The reinforcing fiber bundles A comprise chopped fiber bundles each including 100 or more single fibers. The fiber-reinforced resin material is characterized in that the product of the average porosity within the fiber bundles Pfav (-) and the average fiber-bundle thickness tfav (mm) is 0-0.01 mm and the composite has a porosity Pc (-) of 0.02-0.4. It is possible to provide a fiber-reinforced resin material as a molding material excellent in terms of production efficiency and reduction in LCA, the resin material being capable of giving molded objects with high mechanical properties and having excellent flowability during molding.
