摘要： An enclosure surrounds a jet device for fluid treating a threadline passing through the enclosure. The jet device has a curved surface positioned with respect to the threadline, the stream-forming orifice of the jet and a wall of the enclosure to divert the treating fluid traveling along the threadline away from the threadline and redirect it across the threadline near the threadline passage openings in the enclosure.

摘要： A method of preparing PAN-based carbon fibers relates to the technical field of materials. The method includes: S1. acrylonitrile, a second monomer and an unsaturated UV-sensitive cross-linking agent are mixed, an initiator is then added and a reaction is performed to obtain a meltable PAN-based copolymer; S2. the meltable PAN-based copolymer and a flow modifier are mixed to obtain a mixture, the mixture is extruded and pelletized, and then melt spinning is performed to obtain nascent fibers, the nascent fibers are stretched and annealed to obtain a PAN-based carbon fiber precursor; S3. ultraviolet irradiation is performed on the PAN-based carbon fiber precursor; S4. the PAN-based carbon fiber precursor after ultraviolet irradiation is pre-oxidized and carbonized to obtain PAN-based carbon fibers.

摘要： The present invention relates to a highly contracted artificial fibroin fiber including a modified fibroin, in which a contraction percentage defined by the following equation exceeds 7%.
Contraction percentage={1−(length of contracted artificial fibroin fiber/length of artificial fibroin fiber before being brought into contact with water after spinning)}×100(%)-

摘要： A method for producing an electrocompacted and aligned strand is disclosed. The method includes the steps of: providing a channel having an anode on one side and a cathode on the other side separated by a non-conductive material to form an electrode; dispensing a solution comprising one or more electrocompactable and alignable molecules, nanoparticles or microparticles with ampholytic nature into the channel to complete a circuit between the anode and the cathode; applying a DC current in the range of 1-200 volts to the electrode through the solution in the channel to form an electrocompacted and aligned strand; and transferring the aligned strand out of the electrode. The one or more electrocompactable and alignable molecules, nanoparticles or microparticles with ampholytic nature can comprise collagen molecules that have different charges at different pH values. Materials including electrochemically aligned and compacted compounds are also disclosed.
