Abstract

The invention discloses a spiral plastic steel wire and a production method thereof. The spiral plastic steel wire comprises a fiber forming polymer, wherein the fiber forming polymer is polyethylene glycol terephthalate; the melt index of the polyethylene glycol terephthalate is 15-50g / 10min; the cross section of the spiral plastic steel wire is of a trilobal shape; and the spiral plastic steel wire is of a spiral structure. The production method of the spiral plastic steel wire comprises the following steps: drying the polyethylene glycol terephthalate by a drying tower until the moisture content is below 50ppm, and melting in a screw extruder; extruding the melt through a spinneret orifice, and performing liquid cooling, hot stretch, heat setting and winding to obtain a semi-finished product; and performing spiral twisting treatment on the semi-finished product to obtain the spiral plastic steel wire. The spiral plastic steel wire is prepared by adopting the polyethylene glycol terephthalate as a raw material; and by changing the appearance surface design of the plastic steel wire, the friction is greatly reduced, and the threading wiring construction is more convenient.

Description

technical field [0001] The present disclosure generally relates to the field of monofilaments, and in particular to a spiral plastic steel wire and a manufacturing method thereof. Background technique [0002] Plastic steel wire, also known as curtain wire, uses polyester as a raw material, and is widely used as a screen wire in modern agricultural greenhouses to gradually replace steel wire. Plastic steel wire is widely used in modern agricultural greenhouse projects and online breeding in aquaculture. Its products mainly have two colors, black and transparent. The black plastic steel wire is mainly used for the curtain system outside the greenhouse and the outdoor awning, and it is used as a supporting film wire. [0003] The plastic steel wire can be used as the support wire of the grape trellis. It can completely keep its mechanical properties and geometric dimensions unchanged at the ambient temperature of -40-70°C. Because of its smooth surface, it will not damage gr...
