Problems solved by technology

[0004] The disadvantages of existing PVC coated yarns are: 1. The products of plastic spinning PVC polyester coated yarns are uniform along the length direction, and the main evaluation indicators are the same thickness, linear density, and roundness, which cannot be varied.
2. The fabrics made of existing covered silk obtain various fabric styles through the combination of fabric structure and single-color silk or two-color silk, and there is no appearance style obtained due to changes in the thickness of the wire diameter and the color change of the two-color silk

Abstract

The invention belongs to the technical field of textile plastic fabric, and particularly relates to a controllable diameter-variable and color-ratio-variable coated wire which comprises a core wire and a colored hot melt resin layer coating the outer edge of the core wire. The colored resin layer is monochromatic or dichromatic, and the colored resin layer changes extrusion output of resin along with time parameters to enable the coated wire to have a diameter-variable form and a color-ratio-variable form along the length direction. The invention further discloses a production method of the coated wire. The production method includes that a resin layer extruded out by a screw extruder coats the outer edge of the core wire, rotating speed of a screw of the screw extruder is controlled by aservo motor so as to the extrusion output of the resin layer, the servo motor can be directly connected with the screw or can be in bridging connection with the same through a speed reducer, and the servo motor is controlled by a PLC (programmable logic controller). The diameter-variable coated wire forms bright and colorful changing hue and nonuniform changing wire diameter so as to create a series of new plastic fabric forms.

Description

technical field [0001] The invention belongs to the technical field of plastic textiles for industrial textiles, and in particular relates to a coated yarn with controllable diameter variation and color ratio variation and a production method thereof. Background technique [0002] The production technology of PVC coated wire is similar to the production technology of wire and cable. It is already a common material. Generally, a screw is used to extrude PVC resin coated filament to produce plastic coated wire (thread), which typically uses high-strength polyester industrial yarn as the core. Silk, the outer edge is coated with PVC colored resin. [0003] For example, the Chinese invention patent CN106380719A discloses a preparation method of antibacterial PVC polyester coated yarn, the method includes the preparation of color masterbatch: taking the raw materials of the following components; putting each component raw material into a high-speed mixer for high-speed mixing; st...
