The invention relates to a reflux type static dust removing device. The reflux type static dust removing device is characterized in that an omega-shaped polar plate is disposed on the upper portion of a belt conveyor, a plurality of through holes are formed in the top of the omega-shaped polar plate in an equal-distance manner, insulating tubes are disposed in the through holes, one ends of the insulating tubes are located on the inner side of the omega-shaped polar plate, the other ends of the insulating tubes are located on the outer side of the omega-shaped polar plate, a suspension rod penetrates each insulating tube to be connected with a barb connecting tube, the other end of the suspension rod is fixed on the upper portion of the insulating tube, barb corona wires are disposed on the barb connecting tube in an equal-distance manner, a vibrating motor is disposed on the omega-shaped polar plate, a reflex fan is disposed on one side of the top of the omega-shaped polar plate, an emptying fan is disposed on the other end of the top of the omega-shaped polar plate, a static generator is respectively electrically connected with the suspension rods and the omega-shaped polar plate, and the static generator is grounded. The reflux type static dust removing device has the advantages that the metal sealing cover on the belt conveyor is directly used as the dust collecting polar plate, a dust storage device is omitted, and the device is simple in structure, small in floor space, convenient to mount and maintain and suitable for places in land shortage and limited space.

The invention discloses a regenerated anti-static polyester fiber, which is prepared by melt spinning through a screw extruder after mixing and drying the following raw materials in parts by weight: 30-50 parts of a waste textile fabrication material, 20-30 parts of regenerated polyester bottle flakes, 10-20 parts of polyester master batches, 3-5 parts of a dispersing agent, 3-6 parts of a softener and 5-15 parts of an antistatic agent. Through reasonable utilization of waste resources and proportion design of the antistatic agent, the regenerated anti-static polyester fiber has excellent combination property and anti-static property; the electrostatic problem of puzzling the polyester fiber all the time is effectively solved; meanwhile, effective and reasonable utilization of resources is achieved; the environmental pollution is reduced; and the market prospect is wide.

The invention relates to a preparation method of a polyvinyl chloride (PVC) accessory ingredient, in particular to a high-efficiency environmental-friendly PVC lubricating agent and a preparation method thereof, and belongs to the technical field of plastic products. The high-efficiency environmental-friendly PVC lubricating agent is mainly prepared by mixing the following components in parts by weight: a component A: 5 to 50 parts of fatty acid, 5 to 95 parts of metallic soap, 5 to 95 parts of carboxylic ester, 5 to 95 parts of fatty acid amide, 5 to 95 parts of fatty alcohol, 5 to 95 parts of hydrocarbon wax, 1 to 15 parts of epoxidized soybean oil, 1 to 15 parts of phosphite ester, 3 to 10 parts of polytetrafluoroethylene wax, and 2 to 5 parts of coupling agent; and a component B (whichis calculated on the basis that the total weight of the component A is 100 parts): 0.3 to 0.5 part of peroxide crosslinking agent, and 6 to 15 parts of maleic anhydride. The high-efficiency environmental-friendly PVC lubricating agent has the advantages of capability on improving the compatibility of the lubricating agent and PVC, and good lubrication effect; and meanwhile, the preparation methodof the high-efficiency environmental-friendly PVC lubricating agent is simple in process and applicable to production processing of PVC products in different stable systems.

The invention discloses a cotton spinning and weaving processing technology with an anti-folding function. The technology comprises the following steps of scattering cotton materials in a cotton opening machine to loosen the compacted cotton material into smaller cotton pieces or cotton bundles; making a polyester raw material or a polyester chip raw material extracted from petroleum into a polyester staple fiber; making a nylon raw material into a nylon staple fiber; pouring the cotton raw material after impurity removing, the polyester staple fiber and the nylon staple fiber into a drawing frame to carry out mixing processing so as to form a spun yarn; putting yarn sheets drawn from warps and weft yarns on a weaving machine to carry out weaving; weaving a conductive fiber into a fabric formed through weaving the warps and the weft yarns at equal intervals; and carrying out desizing, scouring and bleaching on a woven fabric through an enzyme, an acid and an oxidizing agent, and carrying out dip dyeing and coloring on a textile in a dye vat. By using the cotton spinning and weaving processing technology with the anti-folding function, problems that a cotton woven fabric is easy tofold, and is easy to shrink after washing so that usage is affected and static electricity is easy to generate can be effectively solved.
