Embodiment Construction

[0012] The present invention is described below through a specific implementation example.

[0013] Purchase carbon black particles with an average particle size of 65±10nm and mix them with PET slices produced by Jiangsu Shenghong Chemical Fiber Co., Ltd. After mixing, carbon black accounts for 20% by mass, and put this part of mixed raw materials into the core component screw. In the silo; another PET chip with the same batch number and the same amount as the core component is selected from Jiangsu Shenghong Chemical Fiber and put into the silo where the skin component screw is located, and then dried, dedusted, melted and extruded, and then entered by frequency conversion metering In the skin-core composite component, the production process is carried out according to the general production process of polyester chip spun staple fiber, and finally the cotton-type conductive polyester staple fiber with a specification of 5dtex×38mm is obtained as required.

Abstract

The invention provides a conductive terylene short fiber production technique, which is characterized in that the skin component is PET, the core component is PET with 10-25% carbon soot nanometer particles; in the production process, the two skin and core components respectively adopt different screws which carry out fusion and extrusion and then are injected into the composite with skin and core structure in an accurate frequency conversion timing manner, and then carry out working procedures such as spinning, winding, severing, packing and so on as the routing of chip spinning; at last, the conductive terylene short fiber of the invention is obtained. Adding 0.6% conductive fiber in antistatic blended yarn can permanently remove the static electrification. The laundry resistance is higher than 200 times.

Description

technical field [0001] The invention relates to a production technology of conductive polyester staple fiber, which belongs to the technical field of chemical fiber production. Background technique [0002] Ordinary polyester staple fiber, because of its fineness and good uniformity, has been the main raw material for blending with natural fibers in various textile mills since its advent and industrial production. Its use can reduce production costs and improve the disadvantages of pure cotton, pure linen, pure wool yarns and fabrics such as poor crispness, poor self-decontamination, and easy pilling. Have good performance. [0003] But because polyester fiber has many deficiencies in performance or function, a very important point is that it is prone to static electricity, so its use as a special fabric becomes impossible. For staff working in such as computer rooms, dangerous goods warehouses, and high-precision laboratories, their clothing, especially work clothes, cann...
